Description
Technical field
The present invention relates to the mixing powder that coal-fired power generator set field, more particularly, to a kind of coal and mud coupling combustion generate electricity
System.
Background technology
Municipal sludge is the discarded object producing in sewage disposal process.According to house and town and country construction portion statistics, year in 2015
End, National urban sewage treatment plant daily handling ability 14028 ten thousand stere, year sewage disposal total amount 428.8 billion cubic meter.Mud
Yield has relation with the height of sewage treatment process and standard, accounts for processing the 0.3%-0.5% of the water yield (with moisture content 97%
Meter), then the mud of sewage disposal process generation in 2015 reaches hundred million tons of 1.29-2.14.Plurality of heavy metal, pathogen is contained in mud
With difficult degradation toxic organic compound, also can emitting offensive odor.If effectively do not process to mud and dispose in addition, can severe contamination ring
Border, impact people's is healthy.Therefore, the process of mud and recycling, it has also become the major fields of environmental protection it
One.
The pretreatment of mud has the technology such as conditioning, concentration, dehydration, stabilisation and mummification, and the final disposal of mud mainly has
Landfill, Land_use change, construction material such as utilize, carry out a biological disposal upon and burn at mode, the emerging technology such as pyrolysis, gasification and pyrohydrolysis

Mud art has the advantages that treating capacity is big, processing speed is fast, innoxious thorough, and application at home is increasing.
At present, because sludge drying-burning engineering that most of thermal power plant puts into operation broadly falls into improvement project, original boiler leads to
Often a kind of pulverized coal preparation system of pattern is only joined it is impossible to directly accept the mud of high-moisture percentage according to the characteristic of design coal, thus mend
Fill arrangement sludge drying workshop and carry out sludge drying, mummification workshop and steam generator system are relatively independent, and distant, dewatered sludge turns
Transport to the coal yard of power plant or special warehouse of sludge, then pulverized coal preparation system is sent into using Belt Conveying mode, or directly pass through spiral shell
Rotation conveying, Geldart-D particle enter in stove and burn.Mud after mummification has airborne dust in stacking and course of conveying and foul smell distributes,
And the sealing property of belt conveyor system is poor, so easily causing foul smell to spread in plant area and near zone, lead to building ring
Border is severe, has a strong impact on the enthusiasm of power plant's burning sludge.
Therefore, Development of Novel pulverized coal preparation system, adapts to common coal and the requirement of mud multifuel combustion on generating plant pulverized coal boiler, is
Carry out the important foundation of sludge incineration disposal by thermal power plant, have positive effect for promoting environmental protection.
