Refuse incineration system efficient in energy utilization

Abstract

The invention discloses a refuse incineration system efficient in energy utilization. An auxiliary fine incinerator is arranged for a main incinerator, during a reaction, the drying and reduction process of the refuse is isolated from the combustion process of the refuse in the auxiliary fine incinerator, and therefore the combustion efficiency in the auxiliary fine incinerator is greatly improved. On one hand, circulating gas enters a high-temperature combustion cavity and is fully combusted, so that the environmental pollution caused by tail gas is reduced; on the other hand, the circulating gas has the combustion supporting function on the high-temperature combustion cavity, so that the combustion effect of the high-temperature combustion cavity is further improved; in addition, high-temperature tail gas in the high-temperature combustion cavity enters an auxiliary heating pipe in the main incinerator and conducts auxiliary heating on the refuse, so that the combustion speed of the refuse in the main incinerator is improved; and the drying and reduction process is accelerated before the refuse is combusted, and therefore the combustion efficiency of the main incinerator is further improved.

Description

technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a garbage incineration system with high energy utilization. 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 on 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; At the same time, the gas produced b...

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 on 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; At the same time, the gas produced by combustion is often not fully burned, causing exhaust pollution
