Method for processing municipal solid waste by using shaft kiln cement production line

Abstract

The invention relates to a method for processing municipal solid waste by using a shaft kiln cement production line. The method comprises the following steps: (1) collecting, separating and warehousing; (2) cutting up, dehydrating and leachate treatment; (3) drying tail gas treatment; (4) burning smoke treatment; (5) slag utilization, raw material ball grinder tail gas treatment; (6) high temperature calcining and tail gas dedusting. The method uses specific conditions of the shaft kiln cement production technology for effectively using heat energy, leachate, slag and the like in the household garbage processing course; simultaneously, all matters generated in the garbage processing course (including taste) are completely dispelled in a high temperature kiln; the method has the advantages of little investment on device reformation, low garbage treatment cost, high waste solid utilization rate, complete garbage treatment and the like, thus truly achieving requirements of minimization, recycling and harmless of the garbage treatment.

Description

technical field [0001] The invention relates to a method for processing domestic waste, in particular to a method for processing urban domestic waste by using a shaft kiln cement production line. Background technique [0002] At present, domestic and foreign municipal solid waste is mainly disposed of in three ways: landfill, high-temperature composting and incineration. Among them, landfill and high-temperature composting are more difficult to select sites for municipal solid waste. It is necessary to consider factors such as topography and geological conditions, and to prevent surface water and groundwater pollution. 1. Land resources are becoming increasingly tight, and the proportion of domestic waste incineration is gradually increasing. However, at present, incineration treatment requires the introduction of incineration equipment, which requires a large investment. The traces of highly toxic substances such as dioxins produced in the incineration process need to be co...

Problems solved by technology

Among them, landfill and high-temperature composting are more difficult to select sites for municipal solid waste. It is necessary to consider factors such as topography and geological conditions, and to prevent surface water and groundwater pollution. 1. Land resources are becoming increasingly tight, and the proportion of domestic waste incineration is gradually increasing. However, at present, incineration treatment requires the introduction of incineration equipment, which requires a large investment. The traces of highly toxic substances such as dioxins produced in the incineration process need to be controlled by special measures. Incineration Most of the final products are landfilled and cannot be effectively utilized
