A cement decomposition kiln coupled with a grate and a process for co-processing domestic waste

Abstract

The invention discloses a cement decomposition kiln coupled with a grate and a process for synergistically disposing of household garbage, which is used to solve the problems of complex components, high moisture content, high sulfur and chlorine content, and high low-temperature volatile component content of the existing household garbage. The process of direct incineration of domestic waste in cement kilns has low heat utilization efficiency, prone to deflagration, clogging of chlorine-enriched crusts in the kiln, and dioxin pollution. The upper part of the cement decomposition kiln coupled with the grate of the present application is provided with a plurality of grate units evenly arranged around the inner wall of the cement decomposition kiln. The inner sleeve, the outer sleeve and the movable sleeve of the grate piece, the movable sleeve protrudes from the upper part of the cement decomposition kiln and is driven by the driving device, and the inner sleeve and the outer sleeve are fixed. The cement decomposition kiln coupled with the grate occupies a small space, has a simple mechanical structure, does not need to replenish fuel, has a large amount of waste treatment, and is completely cracked, and is not affected by the performance of the waste.

Description

technical field [0001] The invention relates to the technical field of domestic waste treatment, in particular to a cement decomposition kiln coupled with a fire grate and a process for co-processing domestic waste. Background technique [0002] my country's annual municipal solid waste production is as high as more than 200 million tons, and the rationalization of waste disposal is particularly important. There are three main ways of waste disposal, including incineration, landfill, accumulation, and incineration is the most important way of waste disposal at present. Grate furnace incineration of waste occupies 60% of the waste disposal market, but there are problems such as high investment cost, large heat loss, and high requirements for the calorific value of waste. Cement decomposition kiln co-processing of waste is also an important way of waste incineration. With the help of the kiln temperature up to 1000 ℃ inside the cement kiln, the harmful substances in the waste...

Problems solved by technology

[0005] The object of the present invention is to provide a cement decomposition kiln coupled with a grate and a process for co-processing domestic waste to solve the problems of complex components, high moisture content, high sulfur and chlorine content and low temperature in the existing domestic waste proposed in the background technology The high content of volatile components leads to low heat utilization efficiency in the process of direct incineration of domestic waste in cement kilns, prone to deflagration, chlorine-enriched crust blockage in the kiln, and dioxin pollution.
