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

[0027] Further description will be made below in conjunction with drawings and embodiments.

[0028] A cement kiln co-processing domestic waste system in this embodiment includes a feed system, a gasification incineration system, a slag discharge system, an odor treatment system, and a leachate treatment system. The feeding system includes a garbage storage pit 2 and a feeding device 5; a crane 4 and a driving grab 3 are arranged above the garbage storage pit 2; the feeding device 5 is connected with the grate furnace 6 of the gasification incineration system, and the garbage Drying, gasification, and incineration in 6, the grate furnace 6 is connected to the cement kiln calciner 13, the flue gas after the grate furnace 6 is burned is sent to the calciner 13; the burnt slag is collected by the slag discharge system and sent to the raw material batching The station participates in batching and grinding into raw material powder. The slag discharge system includes a scraper slag ...

Abstract

The invention discloses a system for synergistically treating domestic garbage through a cement kiln and a method thereof. The system comprises a feeding system, a gasification incineration system, adeslagging system, a smell treating system and a leachate treating system. According to the system, a grate furnace and a cement production process technology are combined, and waste gas produced by garbage incineration is lead into a decomposing furnace of a novel dry cement kiln system, and harmful gas such as dioxin produced by garbage can be further absorbed and treated under about 880 DEG C high temperature and alkaline conditions in the decomposing furnace, thus the garbage treatment meets the requirements of harmlessness, quantity reduction and recycling requirements. The system is simple and convenient to operate, stable to run, small in investment, and low in cements on cement lines and environment, and is an ideal domestic garbage treatment scheme.

Description

technical field [0001] The invention discloses a system and a method for co-processing household garbage by a cement kiln, belonging to the field of urban household garbage treatment. Background technique [0002] With the improvement of people's living standards, the discharge of domestic waste is also increasing. At present, my country's municipal solid waste stockpile has reached 6 billion tons, occupying 500 million square meters of arable land, producing 200 million tons of municipal solid waste every year, and will grow rapidly at a rate of 9%. These large quantities of domestic waste have constituted an increasingly serious threat to the ecological environment in and around the city. Traditional garbage disposal methods include landfill, composting, and incineration. Urban garbage disposal in my country started relatively late, and at present it is mainly sanitary landfill. Although waste incineration and power plants have been established in some cities, due to the...
