Problems solved by technology
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; The combustion efficiency in the furnace body is improved, so that the combustion temperature in the garbage furnace is not high, and the garbage is not completely burned

The invention discloses a waste burning system with gas and solid effective circulation, wherein an auxiliary furnace body is provided for a main furnace body, the pretreated waste in the middle part of the main furnace body is sent into the auxiliary furnace body, and meanwhile, the waste in the auxiliary furnace body is dried, reduced and isolated from a burning process, so that the burning efficiency and burning temperature in the auxiliary furnace body are greatly improved; in a reaction process, the circulation gas, which is insufficiently burnt, in the main furnace body is introduced into a high-temperature burning cavity of the auxiliary furnace body, and meanwhile, high-temperature tail gas in the auxiliary furnace body is introduced into an auxiliary heating pipe in the main furnace body for performing auxiliary heating on the waste, so that on one hand, the insufficiently burnt gas generated in the main furnace body is introduced into the auxiliary furnace body to realize the effect of effectively assisting the burning in the auxiliary furnace body, and on the other hand, the finally generated high-temperature tail gas in the auxiliary furnace body is used for performing auxiliary heating on the waste above a burning layer in the main furnace body, and accelerating the drying and reducing process before the waste is burnt, thereby further improving the burning efficiency of the main furnace body.
Description
technical field [0001] The invention relates to the technical field of garbage treatment, in particular to a garbage combustion system with high-efficiency circulation of gas and solid. Background technique [0002] In recent years, the amount of urban domestic waste has grown rapidly, and the amount of waste accumulated 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; The combustion efficiency in the furnace body is low, so that the combustion ...
