High-temperature environment-friendly combustion method and device for harmless treatment of garbage

Abstract

The invention discloses a high-temperature environment-friendly burning method and device for harmless refuse treatment. Refuse is fed into a burning zone of a burning kiln from feed inlets in the front face, heat after burning is absorbed to a heat storage kiln for heat storage, the heat storage kiln is enabled to reach high temperature internally to remove harmful gas by means of burning, and ash after burning is discharged from an ash discharge layer in the bottom layer of the burning kiln. The device comprises the burning kiln and the heat storage kiln connected with the burning kiln, the burning kiln comprises a burning kiln body, a plurality of burning layers and the ash discharge layer are arranged in the burning kiln body, the burning layers are connected into the heat storage kiln via a passage, the front face of the burning kiln body is provided with the feed inlets, and the lateral surface of the burning kiln body is provided with ash discharge ports. The heat storage kiln comprises a heat storage kiln body, a plurality of separating walls are arranged in the heat storage kiln body longitudinally, a straight-through hole and heat-storage through holes are formed in each separating wall, and a heat outlet is formed in the heat storage kiln body. The refuse is burnt in the burning layers to enable burning to be thorough, burning efficiency is high, discharged hot gas is subjected to high-temperature treatment in the heat storage kiln, and treatment cost is lowered.

Description

technical field [0001] The invention relates to a garbage burning method and device, in particular to a high-temperature environment-friendly burning method and device for harmless treatment of garbage. Background technique [0002] With the improvement of people's living standards, the amount of garbage produced is also increasing, and burning is a conventional way to deal with garbage. Commonly used garbage incineration furnaces are similar in structure to traditional fuel incinerators, but the garbage contains a large amount of inorganic substances that cannot be burned, and also contains a large amount of combustible substances with a low combustion rate, which will produce a large amount of slag after combustion , resulting in the low heat generation rate of the traditional combustion furnace, and it is difficult to clean the slag; and after combustion, a large amount of odor, dust and other harmful substances will be generated, which will affect the environment, so it ...

AI Technical Summary

Problems solved by technology

Commonly used waste incineration furnaces are similar in structure to conventional furnaces using conventional fuels, but the waste contains a large amount of inorganic substances that cannot be burned, and also contains a large amount of combustible materials with a low combustion rate, which will produce a large amount of slag after combustion , resulting in the low heat generation rate of the traditional combustion furnace, and it is difficult to clean the slag; and after combustion, a large amount of odor, dust and other harmful substances will be generated, which will affect the environment, so it needs to be desulfurized and other treatments, and the cost is high
