Problems solved by technology

[0004] (1) The heat required for gasification is not enough;
[0005] (2) The furnace design needs to be further compacted;
[0006] (3) The volume ratio of combustible gas is unstable;
[0007] (4) The contact area between hot air and garbage is too small;
[0008] (5) The traditional grate has few hot air inlets, the volume ratio of combustible synthesis gas is small, and it cannot be sustained and stable
[0010] To sum up, there is a need for a garbage gasification furnace with a telescopic grate structure that can continuously feed materials, have a large contact area between hot air and garbage, and provide enough heat to realize continuous gasification and incineration of garbage. Garbage gasification combustion furnace with grate structure has not been reported yet

Abstract

The invention relates to a garbage gasification combustion furnace of a telescopic fire grate structure and a gasification combustion treatment technology. The garbage gasification combustion furnacecomprises a feed bin, a gasification furnace, the telescopic fire grate structure, a burning furnace, a high temperature resistant fan and a secondary combustion chamber; the upper end of the gasification furnace is provided with a flue gas outlet, the flue gas outlet communicates with the secondary combustion chamber through a pipeline, and the lower end of the gasification furnace is provided with the telescopic fire grate structure; the telescopic fire grate structure conveys garbage in the form of sinusoidal wave motion; the upper end of the burning furnace is provided with a flue gas outlet, the flue gas outlet communicates with the high temperature resistant fan and a drying section of the telescopic fire grate structure through pipelines, and the flue gas outlet of the secondary combustion chamber communicates with the high temperature resistant fan and a gasification section of the telescopic fire grate structure through pipelines. The garbage gasification combustion furnace and the gasification combustion treatment technology have the advantages that continuous feeding can be achieved, the contact area between hot air and the garbage is large, the sufficient heat is provided, and continuous gasification incineration treatment of the garbage is achieved.

Description

technical field [0001] The invention relates to the technical field of combustion furnaces, in particular to a waste gasification combustion furnace with a retractable grate structure and a gasification combustion treatment process. Background technique [0002] The existing waste treatment technologies mainly include incineration, sanitary landfill, composting and so on. In addition, among the conventional technologies for waste disposal, incineration has the characteristics of obvious reduction effect, complete harmlessness, small land occupation, utilization of waste heat, and less secondary pollution, which meets the strategic requirements of my country's sustainable development. As a new type of incineration technology, waste pyrolysis gasification incineration technology has the following advantages compared with direct waste incineration: the gasification process is in a reducing atmosphere, and pollutants such as dioxins and nitrogen oxides are suppressed generation...
