Description

Waste organic waste treatment apparatus and method thereof {TREATMENT APPARATUS FOR ORGANIC WASTE AND METHOD THEREOF}

The present invention relates to an apparatus and a method for decomposing waste organic matter such as manure and food waste using microorganisms, and in particular, the treatment apparatus according to the present invention is a waste gas of the deodorized waste organic matter after heating by a heater Used to heat exchange to maintain the required temperature, it can solve the problems caused by the moisture generated during the decomposition of waste organic materials and contribute to the miniaturization, simplification and power saving of the processing equipment.

In general, waste organic matter such as food waste discharged from homes or restaurants, or manure such as livestock manure has been collected and buried, or processed and recycled into livestock feed or compost.

However, when landfilling waste organic matter, environmental pollution is caused by odors and sewage generated from organic matter, and many types of intangible costs are incurred in the treatment.

In addition, fermentation of waste organic matters is not yet cost-effective, so the research and practical use is slow. In particular, when used as a feed, there are problems with hygiene, which is being questioned in relation to various livestock infectious diseases.

Another problem associated with the recycling of waste organic matter is that it must be collected and disposed of quickly from waste generating sites such as restaurants. Such a task requires rural farming facilities and various restaurants to be distributed throughout the country, so that an appropriate collection of national or local government units is required for proper collection. In reality, however, these large-scale waste collections are costly to countries, municipalities, restaurants and farms.

In addition, when the fermentation of fermented foods is reported to have a detrimental adverse effect on fertilizers or crops, especially when fermented foods are composted, the salinity of the food wastes itself reaches almost 3%, especially in relation to the fertilization of food wastes. Falling. These food salts also have the problem that they can act as toxins in livestock for the feeding of waste organic matter.

Many attempts have been made to treat waste organic waste directly at the place where it is generated, in order to avoid the environmental problems associated with the disposal of waste organic matter and the cost of recycling through large collections.

In particular, fermentation treatment using microorganisms is widely used, and livestock manure is processed through reaction tanks consisting of sedimentation tanks, anaerobic tanks, and aerobic tanks.

Unlike the livestock manure treatment system, it should be able to be installed in a narrow place with regard to food waste disposal, and it should be energy efficient and can be disposed of in a short time.

There have been many patent and utility model applications relating to such waste organic matter, in particular food waste disposal means, which can be classified as related to microorganisms and to devices. Related to the dual device, Korean Patent Publication No. 2001-0113440 (December 28, 2001), Food Waste Disposal Device and Patent Publication No. 2001-0040456 (May 15, 2001), Food Waste Processing Device have.

They are all equipped with a reaction tank equipped with a stirrer, a drive unit for driving the stirrer, a blower for intake and exhaust, a deodorizer for removing odors in the exhaust gas, a heater for the deodorizer and the reactor, and piping for connecting each component. It consists of the general components of.

The most problem in the food waste treatment apparatus having such a general component is the deterioration of microbial treatment efficiency due to the odor and moisture generated during food fermentation. In order to solve this problem, an object of the present invention is to provide a deodorizing means using a catalyst or a microorganism and a means for effectively removing moisture, which is the same in the above-mentioned patents.

In particular, the Patent Publication No. 2001-0113440 to remove the moisture is disclosed a dehumidifying apparatus for condensing moisture to liquefy. And Patent Publication No. 2001-0040456 discloses a dehumidifying means using a dehumidifying agent such as silica gel.

However, all of the waste organic matter treatment apparatus using conventional microorganisms, including such a disclosed patent, was complicated in construction and large in size, making it inconvenient to install. In addition, there was a problem that the energy efficiency is low. The complexity of the configuration and the problem of energy efficiency inevitably put a heavy burden on the maintenance and management of the processing device for the user, and the complexity of the configuration has been a cause of trouble.

The above patents with dehumidifiers, especially for microorganisms requiring constant humidity, further complicate the structure of the device and require a lot of cost and effort to manage such additional devices. In particular, the device of the above-mentioned Patent Publication No. 2001-0040456 using a dehumidifying agent is an additional maintenance cost burden because the dehumidifying agent must be replaced periodically.

The present invention has been made to solve the problems posed by the waste organic matter disposal apparatus, including the food waste as described above, the apparatus and method according to the present invention

First, to provide a structure and a heat exchange means of the reaction tank for heat exchange between the heated exhaust gas and the reaction tank for deodorization,

Second, to provide a structure and method of the reaction tank for heat exchange between the exhaust gas and the outside air to further increase the heat exchange efficiency,

Third, in addition to heat exchange with the exhaust gas to improve the thermal efficiency,

Fourthly, through the heat exchange and heating, the miniaturization and power saving of the waste disposal apparatus is achieved, and the overall temperature of the reactor is kept constant to prevent condensation of water vapor in the reactor, thereby reducing the activity of microorganisms due to moisture and It aims at preventing the reduction of the reactor treatment capacity by this.

In order to achieve the above object, the waste organic matter treatment apparatus according to the present invention is a stirrer is installed inside, the reaction tank having a multi-structure for heat exchange; A driving device for rotating the stirrer; Deodorizer for removing the odor generated when the organic matter is decomposed in the reaction tank; A heater for heating exhaust gas flowing from the reactor into the deodorizer; A blower that sucks the exhaust gas into the deodorizer in the reactor and discharges it to the outside, and introduces outside air into the reactor; A reaction tank, a deodorizer, a heater and a blower are connected to each other for exhaust gas and outside air, and the exhaust gas from the deodorizer is discharged after the reaction tank is heated; And a controller for controlling the driving device, the heater, and the blower.

Hereinafter, an apparatus and a method for treating waste materials according to the present invention will be described in more detail with reference to the accompanying drawings.

As shown in Figure 1a and Figure 1b, the treatment apparatus according to the present invention is largely the reaction tank 10, the driving device 30, deodorization apparatus (D, deodorization apparatus), heater (H), blower (B, blower) , Pipes P1 and P2 and the controller C.

First, the reaction vessel 10 is installed in a housing 10a surrounding all the components of the processing apparatus, as can be seen in FIG. 1A, and an inlet 10b having a opening / closing door 10c is provided at the center of the housing. Formed.

As can be seen in FIG. 2, the reaction tank 10 includes a reaction chamber 11 and a heat exchange chamber 13, and the heat exchange chamber 13 again includes an outside air inlet chamber 15 outside the reaction chamber 11. And the exhaust gas discharge chamber 17 outside the inflow chamber 15.

The reaction vessel 10 of the multi-structure is intended to be discharged after heating the reaction tank 10, rather than being immediately discharged through the deodorizing device (D) after being heated by the heater (H).

Basically, such a heat exchange structure can be achieved with a dual structure of only the reaction chamber 11 and the heat exchange chamber 13 for exhaust gas (which corresponds to the exhaust gas discharge chamber 17 in FIG. 2) as shown in FIG. 1A. have.

However, in the case of using a metal catalyst such as a platinum catalyst, the exhaust gas is heated to about 300 ° C. with a heater (H) for a smooth catalytic action, and the heated exhaust gas is lowered to around 270 ° C. after deodorization. In FIG. 2, if the exhaust gas having a temperature of 270 ° C. is directly contacted with the outside of the reaction chamber 11, there is a risk of harming microorganisms grown at about 40 ° C. to 70 ° C. In FIG.

Of course, the problem is that the optimum exhaust gas temperature is different depending on the catalyst used in the deodorizer (D), the risk will be less when the heat exchanged after the exhaust gas heated to about 150 ℃ to 200 ℃ deodorized.

In addition, the problem caused by the high temperature exhaust gas may be solved by thickening the reaction chamber 11, or may be solved by interposing an insulator or inserting a jacket between the reaction chamber 11 and the exhaust gas discharge chamber 17.

In addition, between the reaction chamber 11 and the exhaust gas discharge chamber 17 may be solved by having a bath room filled with air or water. All such modifications should be construed as falling within the scope of the present invention.

In addition, in order to efficiently exchange heat between the exhaust gas and the reaction tank, the outer surfaces of the reaction chamber 11 and the inlet chamber 15 may have protrusions for wrinkles or endotherms to increase the contact area.

Unlike the reactor 10 having the dual structure of [reaction chamber 11-heat exchange chamber 13] of FIG. 1A, the apparatus shown in FIG. 2 allows the heat exchange between the exhaust gas and the reaction chamber to be carried out at too high a temperature. In order to prevent the risk of the exhaust gas coming into direct contact with the reaction chamber, and to prevent cold air (especially winter air) from directly affecting the reaction chamber 11, the structure of the reaction tank 10 is changed to [reaction chamber 11-outdoor air]. Inlet chamber 15-exhaust gas discharge chamber 17]. In this case as well, in the initial stage of inflow of the outside air, a separate means described below is proposed so that the original temperature of the outside air does not directly reach the reactor.

The reactor 10 is provided with a stirrer 20 for mixing the sawdust fixed with microorganisms such as food waste and the waste organic matter. As shown in FIG. 2, the stirrer 20 is composed of a central axis 21 and a stirring pin 23 that is regularly or irregularly vertically attached about the axis 21, and also has a stirring pin 23. ) Is provided with a stirring blade 25 for increasing the efficiency of the stirring. The stirring wing may be in various forms such as a polyhedron or a vortex, such as a plate or a cube.

It is preferable that the longitudinal cross-sectional shape of the reaction tank 10 is U-shaped so that the waste organic matter is smoothly mixed by the stirrer 20.

In addition, as shown in Figure 4, the stirring blade 27 of the stirring pin 23 is coupled to the stirring pin, the cross section is a rhombus shape and the coupling portion 28 is formed with a coupling hole 28a, this coupling portion It would be more suitable for the agitation of the waste organic matter consisting of a flat plate 29 in the form of a bent plate attached to two sides of (28). In particular, the edge of the flat plate 29 is in the direction of rotation of the stirrer, it is preferable to reduce the friction while stirring the waste organic matter well. In addition, the coupling portion 28 is omitted, it is also possible that the plate 29 is directly welded to the stirring pin (23).

The stirring pin 23 is a simple rod-shaped as well as the cross-section of the polygon (not shown) is suitable for coupling and fixing with the stirring shaft 21 and the stirring blades 25, 27. In this case, the coupling hole 28a of the wing 27 shown in FIG. 4 should also have a corresponding polygonal shape. These wings 27 may be formed in one piece or a combination of several assemblies, it is not limited to the shape and manner of assembly.

As shown in FIGS. 1A and 1B, the stirrer 20 is rotated by the driving device 30. The drive device includes a motor 31, a drive sprocket 33 connected to the rotation shaft of the motor, a driven sprocket 35 coupled to the stirring shaft 21 of the stirrer 20, and two sprockets 33 and 35. ) Is composed of a chain 37 connecting. However, any device capable of transmitting the rotational force of the motor 31 to the stirrer 20 is possible, so the present invention is not limited by the particular drive shown.

Next, as shown in Figure 1b and 2, the deodorizing device (D) of the present invention is the waste organic matter is released by the microorganism in the reaction chamber (10) reaction chamber 11 by the suction force of the blower (B). As the exhaust gas flows in, the odor is removed.

Common odor removal includes concealment that prevents odor from other odors such as fragrance, adsorption method such as silica gel, charcoal or activated carbon, absorption method that absorbs and removes with cleaning solution (washing method ), and condensation of odorous substances using cooler. Physical methods such as the condensation method (cooling method ), chemical cleaning methods such as neutralizing reactions and oxidation reactions using chemicals, and chemical treatment methods such as ozone oxidation and liquid phase catalysts to deodorize the odor components. the biological methods by impregnating a chemical method, the microorganism itself or the enzyme embellish the microorganisms is created that has a function to decompose the components of the odor, such as carbon dioxide and combustion method for decomposing oxidation of water on a support, such as inorganic solids removed by using a deodorant have.

The dual combustion method is simple and inexpensive , but is effective in eliminating odor. Combustion methods include direct combustion method and catalytic oxidation method. The direct combustion method is a method of oxidizing and burning odorous substances above the ignition temperature (600-800 ° C) with a flame. The catalytic oxidation method is a method of treating an odorous substance in an oxygen-containing gas to an odorless state by performing combustion or pyrolysis reaction at a relatively low temperature (150-400 ° C.) by the action of a catalyst.

Is the catalyst oxidation is by again to the liquid phase catalyst of the Fe system odor component materials are oxidized and decomposed at room temperature the catalyst itself is reduced by the O ₂ in the air activation energy wall and a liquid oxidation process is returned to the original state, by use of a catalyst There is a solid catalytic oxidation process that lowers the temperature so that complete decomposition can occur at much lower temperatures than in normal combustion.

In the present invention, there is a problem that the liquid oxidation method cannot be used under high temperature conditions of 40 ° C. or higher in consideration of heat exchange, and thus a deodorizing device (D) is constructed by using a solid catalyst oxidation method.

In general, in the solid catalyst oxidation method, a platinum catalyst having excellent activity and heat resistance and good endothelial toxicity is supported on a carrier (gamma alumina, etc.).

At this time, halogen element, lead, zinc, mercury, sulfur, dust, moisture, etc. causes problems of catalyst poison that degrades the performance of the catalyst. ) Is preferably provided. Furthermore, it is more preferable that such a filter (F) is arranged in front of the blower (B) so that foreign matter does not adversely affect the blower. However, the spirit of the present invention should not be limited by the arrangement position of the filter F.

The filter F used a metal filter for semi-permanent use, but may be a ceramic or resin type and a chemical filter.

Catalysts used in the deodorizer (D) include Co ₃ O ₄ , PdO, Cr ₂ O ₃ , Mn ₂ O _3, CuO, SeO ₂ , FeO ₃ , Fe ₂ O ₃ , V ₂ O ₅ including platinum (Pt) , NiO, Ag, MoO ₃ , TiO ₂ -based metals may be used, and in particular, these metal catalysts may be manufactured and used in the form of honey combs.

As shown in Figure 1b and 2, the heater (H) is provided for the appropriate temperature of the deodorizing device (D) of the metal catalyst series. For example, in the case of a deodorization device (D) using a platinum catalyst, an exhaust gas temperature of about 300 ° C. is required for proper deodorization.

This heater H is also used to preheat the outside air as previously described so that the original temperature of the outside air does not directly affect the reactor 10 so that the temperature in the reactor for the microorganisms by the outside air is not lowered. can do. This may not only increase energy efficiency but also contribute to maintaining the humidity required for microorganisms (see FIG. 3).

In general, microorganisms require aerobic or anaerobic conditions and appropriate temperatures suitable for growing environments, and in order to efficiently reduce (decrease or extinguish) waste organic matter, it is necessary to control the flow rate required to maintain a constant pressure and evaporate in the reactor. . It also requires adequate humidity.

The humidity, that is, the moisture content, affects the decomposition rate and odor generation of food waste, and it is necessary to maintain the optimum moisture content in order to efficiently treat food waste.

Usually the most desirable water content is 20-40 (w / w%), and it is necessary to moisturize or remove the bacteria to maintain this water content.

However, the waste organic matter, especially food waste in our country contains a lot of water, so the point of the waste organic waste treatment apparatus generally has to meet the removal of water.

If the water content is lower than 20%, the water flows from food wastes to foods smoothly, so that the processing speed seems to be faster, but the microbial activity is weakened due to the drying of foods and food wastes. Falls. In addition, when the moisture content exceeds 40%, the microorganism becomes excessive with the moisture of the food waste, and the oxygen supply to the bacteria is insufficient. As a result, the reproduction of aerobic bacteria is deteriorated, while anaerobic bacteria are activated to degrade the degradation. In addition, odorous substances such as hydrogen oxide, mercaptan (CH ₃ SH), and organic acids remain to reduce treatment efficiency.

Conventional waste disposal apparatus, including the previously disclosed patents, is provided with a separate device for the removal of moisture for the treatment device according to the domestic reality in relation to problems caused by the humidity, in particular with respect to food waste.

However, the present invention is not only equipped with a suitable heat insulator (not shown) to prevent moisture generated during the waste organic matter decomposition process of the microorganisms from the upper part of the reaction chamber, and to activate the microorganisms used at a high temperature of about 40 to 70 ℃ I'm considering using it.

In particular, this maintains the temperature and while preventing condensation of moisture configure ① reaction tank 10 as described above to a moisture in the gas state to be smoothly discharged to multiple reaction heat of the exhaust gas chamber (11, in Figure 1a double in the case of a reaction vessel) or the inlet the inlet chamber (15, and provides the heat exchange structure, ② device initially entering the reaction chamber (11 a of the outside-air operation to be passed for a triple reactor of Fig. 2)) for the outside air that is In order to prevent the outside air temperature from being immediately applied, a method of allowing the outside air to flow through the heater H is provided (in the case of FIG. 2).

1B and 3, the blower B not only sucks and discharges exhaust gas from the reaction chamber 11 of the reaction tank 10, but also allows outside air to flow into the reaction chamber 11.

It is possible to induce the circulation of the gas by providing a separate blower for the exhaust gas and a blower for the outside air. However, in the present invention, when the opening and closing door (10c) of the reaction tank 10 in order to save energy, the reaction tank is completely sealed, and the reaction with the outside as the exhaust gas is discharged from the reaction chamber 11 by one blower (B) The pressure difference with a seal | sticker arises, and the air | atmosphere is taken into the reaction chamber 11 in this way.

Such a blower (B) generally has a root type (root's blower) and a ring type (ring blower). In the present invention, a centrifugal force type and a motor direct type have a low vibration and noise, and a ring type with easy flow rate and wind pressure control may be preferable. .

The operation of the waste disposal apparatus as described above will be described with reference to the drawings.

In FIG. 3, the pipes connecting the components are divided into exhaust gas P1 and outside air P2. The exhaust gas pipe P1 includes the exhaust gas discharge chamber 17 of the reaction chamber 11, the blower B, the filter F, the heater H, the deodorizer D, and the heat exchange chamber 13 of the reactor 10. ) Is connecting.

And the outside air piping P2 connects the outside air inflow chamber 15 among the heater H and the heat exchange chamber 13. If a separate blower is provided for inlet air, the pipe (P2) should also be connected to this blower.

The waste agitator, such as sawdust and food waste, in which microorganisms are fixed, is put into the reaction chamber 11 of the processing apparatus, and then the power is turned on.

At this time, by placing a suitable grinder (not shown) in the apparatus of the present invention, it is possible to increase the treatment efficiency by being put after the solid solid, such as bone or wood is crushed, it is possible to prevent the crowd going to the stirrer due to such a solid have.

For the aerobic conditions of the microorganisms, the outside air (see the dotted arrow) is heated by the heater H while being purified by the blowing force of the blower B, in particular, the pressure difference between the reaction chamber 11 and the outside as described above. Again, the inlet 15a flows into the outside air inlet chamber 15. Subsequently, it enters the reaction chamber 11 out of the inlet chamber 15 through the outlet 15b.

As shown in FIG. 2, the outlet 15b may be in the form of a suction pipe 16 in which a suction hole 16a is formed.

As the waste organic matter is fermented / decomposed by the microorganisms, gas is generated, which is released from the reaction chamber 11 by the suction force of the blower B (see solid arrow in FIG. 3). At this time, the structure for the discharge is in the form of the discharge tube 18 is formed with the discharge hole 18a disposed opposite the suction tube 16, as shown in Figure 2 evenly suction and discharge of the exhaust gas and the moisture contained in the exhaust gas Would be suitable for

The heating of the outside air by the heater (H) may be heating by direct contact, but in this case, if the heating is higher than the growth temperature of the microorganisms to enter the reaction chamber 11 may harm the microorganisms. In particular, this point will become more serious when the heater H for the deodorizer D is also used for heating the outside air, when the heating temperature of the heater H is set to 300 ° C., for example for the platinum catalyst.

Of course, such a problem may be solved by using a blower for inlet air to speed up the inlet air. In addition, a heater set to a low temperature for the outside air can be solved separately from the heater for the deodorizer. However, all of these inevitably require larger processing equipment and additional energy consumption.

In the present invention, while solving this problem using only the heater (H) or the case (HC) surrounding both the heater and the deodorizer (D) as shown in FIG. That is, as shown in the drawing, both the heater and the deodorizing device are spaced apart from these, connecting the pipe (P2) for the outside air to the case (HC) where the space is formed, the outside air flows in accordance with the discharge of the exhaust gas case (HC) After circulating the internal space is introduced to the outside air inlet chamber (15). Such a method may be referred to as an 'indirect' heating method which is largely different from a 'direct' heating method of a heater. In this case, one heater (H) is shared for the heating of the deodorizer (D) and the outside air, even if the heater is set to a temperature (for example, 300 ℃) for the deodorizer (D), because it is indirectly heated to a low temperature (eg : 40 to 70 ° C.).

At this time, the indirect heating temperature of the outside air may be controlled by the inflow rate of the outside air. When the indirectly heated outside air is heat exchanged with the exhaust gas deodorized again as shown in FIG. 3, it may be preferable to heat the temperature to about 40 ° C.

In addition, in the structure in which the exhaust gas flows into the heat exchange chamber 13 to discharge the exhaust gas after heating only the reaction chamber 11 as shown in the reaction tank 10 of FIG. 1A, outside air flows directly into the reaction chamber 11. At this time, when the optimum growth temperature of the microorganism is 70 ℃, the inflow rate of the outside air into the case (HC) can be made slower to indirect heating temperature of the outside air to about 70 ℃.

In FIG. 3, when the exhaust gas deviates from the reaction chamber 11 by the suction force of the blower B, the exhaust gas flows into the filter F for pretreatment. As described above, the filter F may be arranged before or after the blower B.

Subsequently, the exhaust gas is heated through the heater H so that the exhaust gas is heated to an appropriate temperature (300 ° C. in the case of the platinum catalyst) for the deodorizing device D made of the metal catalyst. After being deodorized by the deodorizing apparatus, the reaction tank 10 is introduced into the exhaust gas discharge chamber 17 of the outermost part through the inlet port 17a. The exhaust gas temperature after deodorization is expected to be 260 to 280 ° C when the heating temperature is for example 300 ° C.

The introduced exhaust gas is heat-exchanged with the outside air introduced into the inlet chamber 15 and then discharged to the outside via the outlet 17b.

The above blower B, the heater H, and the stirrer 20 are controlled by the controller C (see the dashed line in FIG. 3), and the blower B is equipped with a load sensing sensor (not shown). Overload can be prevented and the overall reaction can be stopped in case of overload. In addition, the motor 31 of the driving device is equipped with a timer (twin timer, not shown), for example, it is possible to maintain a three-minute operation, a 20-minute rest. And the heater (H) is also equipped with a thermal monitoring sensor (not shown) it can prevent the danger.

The waste organic matter treatment apparatus described above may be more clearly understood through the following embodiments related to the food waste dissipator.
