NOVELTY - Garbage sorting and pyrolysis treatment, involves sorting, crushing and secondarily sorting garbage to sort recyclable constituents in garbage into 3 sorts, where the first sort is pyrolyzed raw material 1 such as paper and plastic, crushing the three sorts of mixtures, mixing the crushed second and third sort of mixture and then fermenting aerobically, using the penetrating fluid in direct back-ejection and evaporation in high temperature area, secondarily sieving obtained product to obtain pyrolyzed raw material 2, mixing the pyrolyzed raw materials, and then drying.    USE - The comprehensive utilization method is useful for garbage sorting and pyrolysis treatment for generating electricity (claimed).    ADVANTAGE - The method is environmental-friendly, and has high recycling rate and less energy consumption.    DETAILED DESCRIPTION - Comprehensive utilization method for garbage sorting and pyrolysis treatment, where the technical method is facilitated in urban household garbage sorting and pyrolysis treatment system which comprises garbage primary sorting crusher, roller airflow sorting device, ferment pond, sieving device, slice device, drying device, nitrogen protecting microwave heating garbage sorted substance pyrolyzing and carbon activating integrated furnace, combustion gas turbine and afterheat boiler. The method involves (1) sorting and crushing the urban household garbage by the mixed garbage primary sorting crusher in the garbage treating system and extracting the hard substances such as battery, metal and organic matters, and sorting the recyclable constituents in garbage into three sorts by the secondary sorting of the roller airflow sorting device, where the first sort is the light combustible paper such as paper and plastic in which the water content is less than 25% and the light combustible paper is used as the pyrolyzed raw material 1, the second sort is the mixture of mud and kitchen wastes having high water content, and the third sort is the mixture of rag, fresh branches and stems having high water content, (2) slicing the third sort of mixture by the slice device in the garbage treating system, and mixing the sliced third sort of mixture with the second mixture comprised of mud and kitchen wastes, (3) aerobically fermenting the second and third sorts of mixtures in the ferment pond of the garbage treating system and dehydrating, aerobically fermenting for 15-20 days to remove 70-75% of water content in the second and third sorts of mixtures, where the comprehensive water content in the discharged material is less than 22%, and using the penetrating fluid produced in the step in the direct back-ejection and evaporation in the high temperature area, (4) secondarily sieving the fermented and dehydrated product by the sieving device of the garbage treating system, sieving out the plant, residual fibers of kitchen wastes, rags and high thermal value organic material of synthesized organic sort, which have high thermal value, high fixed carbon fiber content and fully removed carbohydrate, using the sieved product to extract the raw material of fiber activated carbon, and then using as the pyrolyzed raw material 2, where the rest sieved materials are the mixture of fermented product of the degradable constituents of animals and kitchen wastes and the organic constituent such as mud, and using the sieved materials with constituents and harmless index that reach the standard of agricultural compost as the raw material refined compost, (5) preparing the pyrolyzed raw material 1 and pyrolyzed raw material 2 according to standard measurement of the average typical constituent content of garbage to obtain the pyrolyzed raw material, (6) drying the pyrolyzed raw material by high-efficient steam heat exchanging type stirring drying device of the garbage treating system, reducing the water content of the pyrolyzed raw material to be within 5%, recycling the steam produced by the heat source used by the drying device by the afterheat of electricity generation of the combustion gas turbine in the garbage treating system, refluxing the hot water produced after the steam is condensed to the afterheat boiler of the electricity generating system and using as the replenishing water, (7) pyrolyzing the garbage sorted substance of the pyrolyzed raw material and recycling the pyrolyzed solid product as product in the garbage sorted substance pyrolyzing furnace of the garbage treating system to obtain carbon dioxide, saturated steam, artificial coal gas and activated carbon coarse product, and (8) utilizing the comprehensive heat in the pyrolyzed vapor, using the obtained combustible artificial coal gas to carry out the gas combustion electricity generation by the conventional low thermal value gas combustion gas turbine, recycling the afterheat of the high temperature tail gas produced by the combustion gas turbine by the afterheat boiler, and using the steam produced by the afterheat boiler as the heat source of the drying process of pyrolyzed raw material, where some of the water used by the afterheat boiler is from the reflux hot water of the dryer and the other portion is replenished by the running water.
