Problems solved by technology

Although waste incineration and power plants have been established in some cities, due to the small amount of treatment, the treatment process is accompanied by harmful gas (dioxin), sewage (garbage leachate), waste residue (high content of heavy metals) and other discharge problems. The incineration method is still controversial

Embodiment Construction

[0029] Further description will be given below in conjunction with the accompanying drawings and embodiments.

[0030] A power generation system for co-processing domestic waste with cement kilns in this embodiment includes a waste receiving and storage system, an incineration system, a leachate treatment system, an odor treatment system, a waste heat boiler system, a turbine power generation system, and a flue gas purification system. The invention combines cement production, garbage disposal and garbage power generation to form a brand-new garbage disposal technology, which not only has the advantages of the traditional garbage incineration method, but also solves the problem of dioxin and garbage. The problem of ash handling.

[0031] The receiving and storage system includes an unloading hall 1, a garbage storage pit 3 and a feeding device 6; a garbage truck 5 and a grab 4 are arranged above the garbage storage pit 3, and the grab 4 sends the garbage to the feeding device ...

Abstract

The invention discloses a cement kiln cooperative processing domestic garbage power generation system and method. The power generation system comprises a garbage receiving and storage system, an incineration system, a filtered liquid treatment system, an odor treatment system, an afterheat boiler system, a steamer power generation system and a flue gas purification system. The cement kiln cooperative processing domestic garbage power generation system combines three process technologies, namely, cement production, garbage treatment and garbage power generation, and adopts a brand new garbage treatment technology which carries out harmless treatment on waste gases and ash residues generated by garbage incineration and the garbage filtered liquid and effectively utilizes the waste gases, ashresidues and the garbage filtered liquid. The technology solves the difficult problem of treating dioxin and garbage ash residues very well in addition to the advantages of a traditional garbage incineration method.

Description

technical field [0001] The invention relates to a power generation system and method for co-processing domestic waste in a cement kiln, and belongs to the field of urban domestic waste treatment. Background technique [0002] With the improvement of people's living standards, the discharge of domestic waste is also increasing. At present, the stockpile of municipal solid waste in my country has reached 6 billion tons, occupying 500 million square meters of arable land, producing 200 million tons of municipal solid waste every year, and it will grow rapidly at a rate of 9%. These huge quantities of domestic waste have posed an increasingly serious threat to the ecological environment of cities and their surrounding areas. The traditional waste disposal methods include landfill, composting and incineration. my country's urban waste treatment started relatively late, and currently it is mainly based on sanitary landfill. Although waste incineration and power plants have been ...
