Efficient garbage incineration system

Abstract

The invention discloses an efficient garbage incineration system. An auxiliary fine incineration furnace is arranged, circulating gas in a main incineration furnace is sent into the auxiliary fine incineration furnace for assisting in combustion, and tail gas in the auxiliary fine incineration furnace returns into auxiliary heating pipes of the main incineration furnace to assist in heating. In the reaction process, fine material closed incineration is performed in the auxiliary fine incineration furnace, so that the furnace temperature of the auxiliary fine incineration furnace is greatly higher than that of the main incineration furnace; on one hand, the gas which is not fully combusted and generated by the main incineration furnace enters an auxiliary furnace body for further combustion, and the effect of assisting in combustion in the auxiliary furnace body is effectively achieved; and on the other hand, the high-temperature tail gas finally generated by the auxiliary fine incineration furnace performs auxiliary heating on garbage above a combustion layer in the main incineration furnace, before the garbage is combusted, the drying and reduction processes are accelerated, and thus combustion efficiency of the main incineration furnace is further improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a high-efficiency garbage incineration system. Background technique [0002] In recent years, with the improvement of people's living standards, the generation of municipal solid waste has increased rapidly, and the stock of waste accumulation over the years has been huge. It is usually disposed of by landfill, causing waste to erode a large amount of land. The incineration method can maximize the effective treatment of domestic waste and occupy the least land resources. However, if the incineration tail gas is discharged directly without treatment, it will cause serious air pollution. When the garbage incineration furnace is working, on the one hand, the opening at the top of the furnace body is convenient for continuous feeding into the furnace, so that the furnace temperature cannot reach the ideal high temperature; As a result, the combustion temperature in the ga...

It is usually disposed of in landfill, causing waste to erode a large amount of land

The incineration method can maximize the effective treatment of domestic waste and occupy the least land resources. However, if the incineration tail gas is discharged directly without treatment, it will cause serious air pollution.

When the garbage incineration furnace is working, on the one hand, the opening at the top of the furnace body is convenient for continuous feeding into the furnace, so that the furnace temperature cannot reach the ideal high temperature; As a result, the combustion temperature in the garbage furnace is not high, and the garbage is not completely burned
