Vertical shaft multiple incinerator for refuse pyrolysis, gasification and fusion

Abstract

The invention discloses a vertical shaft multiple incinerator for pyrolysis, gasification and fusion. The vertical shaft multiple incinerator for pyrolysis, gasification and fusion comprises a vertical coaxial structure incinerator body, a main combustion chamber and a secondary combustion chamber outside the main combustion chamber are arranged in the incinerator body, the main combustion chamber and the secondary combustion chamber are of a horizontal multiple coaxial structure, an annular fusion combustion hearth is arranged between the main combustion chamber and the secondary combustion chamber, a high temperature fusion wall and a rotary fire grate are arranged in the combustion hearth, a shaft-less spiral conveying discharging device is arranged on an incinerator cover on the top of the incinerator body, a deslagging mechanism is arranged on the lower portion of the incinerator body, and a driving device of the rotary fire grate is arranged outside the incinerator body. The vertical shaft multiple incinerator for refuse pyrolysis, gasification and fusion is stable in combustion and reliable in operation; because smoke can stay for a long time at high temperature, it can be guaranteed that dioxin pollutants in the smoke can be fully decomposed and the smoke reaching the standard is discharged; because combustion assisting agents do not need to be added, operation cost is low and floor area is small.

Description

technical field [0001] The invention relates to the technical field of solid waste pyrolysis and incineration equipment, in particular to a vertical shaft duplex generator set that is used for pyrolysis, gasification, melting and incineration of toxic and harmful solid waste such as household garbage, industrial garbage, medical garbage and sludge. Garbage pyrolysis gasification melting incinerator. Background technique [0002] At present, the main methods of disposing of various types of garbage at home and abroad include incineration, composting and sanitary landfill. Compared with the three methods, the incineration method is the best way to harmless, reduce and recycle municipal solid waste. It has the obvious advantages of low one-time investment, less land occupation, moderate operating cost, and protection of water resources and land from pollution. [0003] Municipal solid waste incineration equipment can be divided into mechanical grate incinerator, fluidized bed...

AI Technical Summary

Problems solved by technology

[0004] However, the fluidized bed incinerator technology uses auxiliary fuel, and the garbage must be sorted and crushed in the first place. The power consumption is high, the operating cost is high, and the flue gas is difficult to meet the standard; the grate furnace technology is mature, and the single furnace has a large processing capacity. Application examples Many, but the investment and operation costs are high, and the flue gas is difficult to meet the standard; the rotary kiln incineration technology is mainly used for the incineration and disposal of hazardous waste, but it basically fails in China

Large equipment investment, difficult installation, auxiliary fuel needs to be added during incineration, high failure rate, high maintenance cost, and difficulty in flue gas compliance
