Operation principle of the present invention: carbonizer waste heat exports to after heat exchanger heat exchange through high-temperature gas conduit, and Cryogenic air heats by heat energy, then it is inner to introduce desiccation machine through hot blast unit, heat material, after material is heated, moisture diffusion is in hot blast; Hot blast is derived to enter in dehumidifier by return air unit and is carried out dehumidifying, dewatering, and the air after dehydration enters in heat exchanger through exhaust gas processing device and heats, and after heating, then it is inner to introduce desiccation machine by hot blast unit.And so forth, constantly take away the moisture in material, thus make material be reduced to setting moisture content from high-moisture.
The present invention be by the carbonizer course of work produce high-temperature tail gas and carry out heat exchange and change heating, after heating, heated material and air in fixing space, after moisture enters air, through dehumidifier, water is converted into liquid state by gaseous state, thus reaches the object of material mummification.
Present invention utilizes the waste heat that carbonizer produces, reach the target of energy-saving and emission-reduction; Mummification temperature controls, within 70 DEG C, effectively to maintain organic physicochemical property, and avoids the generation of foul gas; Air recycling after dehumidifying, reduces energy consumption further; The aqueous water produced is distilled water, non-secondary pollution.
The present invention's advantage is compared with prior art: compared with the charing of the present invention and traditional organic solid castoff and anhydration system, have great cost advantage; Mummification temperature within 70 DEG C, does not change the physicochemical property of material, and the value of material is retained; Air reciprocation cycle after dehumidifying utilizes, and energy-saving effect is more obvious, and discharges without gas, avoids the generation of secondary pollution.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, a kind of organic solid castoff high temperature carbonization and anhydration system with residual heat using device, comprise carbonizer 1, desiccation machine 2, heat exchanger 3, hot blast unit 9, return air unit 7, dehumidifier 5 and exhaust gas processing device 4, described carbonizer 1 connects desiccation machine 2 by screw input feeder 12, is provided with distributing device 6 and spiral discharging device 11 in desiccation machine 2; Described hot blast unit 9 is arranged on bottom desiccation machine 2, return air unit 7 is arranged on desiccation machine 2 top, described carbonizer 1 connects heat exchanger 3 and hot blast unit 9 successively by high-temperature gas conduit 2, and described return air unit 7 connects dehumidifier 5, exhaust gas processing device 4 and heat exchanger 3 successively by return air duct 13.
Operation principle of the present invention: carbonizer 1 waste heat exports to after heat exchanger 3 heat exchange through high-temperature gas conduit 2, and Cryogenic air heats by heat energy, then it is inner to introduce desiccation machine 8 through hot blast unit 9, heat material, after material is heated, moisture diffusion is in hot blast; Hot blast is derived to enter in dehumidifier 5 by return air unit 7 and is carried out dehumidifying, dewatering, and the air after dehydration enters in heat exchanger 3 through exhaust gas processing device 4 and heats, and after heating, then introduces desiccation machine inside by hot blast unit 9.And so forth, constantly take away the moisture in material, thus make material be reduced to setting moisture content from high-moisture.
The invention belongs to the category of using waste heat from tail gas regeneration, power plant, cement plant using waste heat from tail gas regeneration know well by the public.But high temperature carbonization system waste heat being carried out organic solid castoff drying technique, to be applied to organic solid castoff process field be then new trial, and be considered to a kind of up-and-coming organic solid waste mummification mode, also the popularization for organic solid castoff high temperature carbonization treatment technology is provided support.
