Description

Municipal solid wastes maintain glow processing platform system and processing method certainly
Technical field
The present invention relates to field of environment engineering, is specifically related to municipal solid wastes and maintains processing platform system of glowing certainly And processing method.
Background technology
The conventional heat treatment technics of municipal solid wastes disposal at present includes burning, pyrolysis, gasification and hydro-thermal charing etc., The difference of these heat treatment technics is the difference for being passed through reacting gas composition, operation temperature and pressure, and its common drawback is Energy consumption is big and cost is high, reacting furnace design and processes complex operation, limits the processing of municipal solid wastes.According to statistics, entirely State and Cities of Jiangsu Province solid waste treating capacity only account for 24.18% and 2.7% (referring to Fig. 1) of production respectively, cause Substantial amounts of municipal solid wastes accumulation, has occupied the urban land resource of preciousness, seriously hinders Chinese Urbanization development.Cause This, municipal solid wastes processing is China's urban development and environmental improvement major issue urgently to be resolved hurrily.Develop low-consumption high-efficiency Municipal solid wastes processing new technology have important practical significance to solving the problem and social economic effect.
By taking municipal solid wastes incineration disposal method as an example, its processing step is:
1) early-stage preparations
Municipal refuse is transported to incineration plant by rubbish closeding transporting vehicle, is weighed, stored, leachate treatment etc..
2) filler
Municipal refuse is through grab bucket, feed hopper and pusher, into incinerator.
3) burn
By taking two-period form as an example, garbage incinerator fire grate is divided into backstepping section and forwards section Liang Ge combustion zones, and its main flow is: Rubbish is sent into charging conduit by grab bucket from garbage pool, and burner hearth is entered under the push of batcher, is fallen on inclined backstepping fire grate, rubbish Rubbish constantly rolls on bed surface, stirred, and completes to dry, catches fire and combustion process, then in the end of backstepping fire grate, by one section Drop, fall on horizontal forwards fire grate bed surface, burn away, until after-flame.
4) waste gas, Solid state fermentation
The qualified discharge after exhaust gas processing device purifies of flue gas caused by burning, clinker caused by burning can be used as general Waste processing, the flying dust of sack cleaner processing add cement and chelating agent curing process as hazardous waste.
Following major defect be present in this method:
1) high heat consumption
By taking two-period form type incinerator as an example, the burning of the incinerator need it is outside thermal source is provided, make incineration temperature 800~ In l050 DEG C.This incineration disposal mode needs substantial amounts of outside heat to supply, and is added significantly to cost of disposal.
2) technics comparing is complicated
To furnace temperature, the control of gas residence time, technological operation difficulty is added.Required during incineration disposal, when warm in stove When degree is more than 850 DEG C, gas residence time > 2s, oxygen concentration 7.26% (is controlled 5.6~10.7%).This is to a certain degree On increase technological operation difficulty.
3) poisonous and harmful flue gas generation
In flue gas out of stove in discharge process, if the residence time of flue gas (600~200 DEG C) process from high temperature to low temperature It is longer, bioxin may be generated.
The content of the invention
The shortcomings that existing for current municipal solid wastes thermal treatment technology, the present invention is directed to propose a kind of low consumption, height The simple municipal solid wastes of efficiency, operating procedure maintain glow processing platform system and processing method certainly.

6)Heating igniting:Under conditions of gas circuit closing, ignition control device is opened, the heating power pair set using back Municipal solid wastes are heated, after the municipal solid wastes temperature in reacting furnace reaches default firing temperature, control Software systems processed will turn off ignition controller;
7)Supply regulation and control:After ignition controller is closed, system will automatically turn on flow controller and be passed through air, observe central shaft The change of upper electric thermo-couple temperature, the electric thermo-couple temperature above ignition controller all persistently rise, and continuous when there is stable peak, Show municipal solid wastes can self―sustaining sustained combustion until solid waste after-flame, when solid waste in reacting furnace After all burnt, source of the gas is closed;
8)Flue gas monitoring and processing:Flue gas analyzer is monitored to flue gas, and the flue gas caused by disposal that glows passes through fume extractor Discharge;
9)Solid residue is analyzed and processing:The base is separated with the body of heater, collects solid residue after processing of glowing, Then its quality and volume are measured, calculates volume-diminished ratio and disposal efficiency.
