Domestic garbage incinerator and method for treating domestic garbage

Abstract

The invention discloses a domestic garbage incinerator. The incinerator is characterized by comprising a foundation base, a furnace base, a hearth body, a furnace frame, a feeding device, a combined fire grate mechanism, a furnace bottom ash outlet hopper, a slag outlet hopper, an ash outlet mechanism, a slag breaking mechanism, a slag fall channel, air cabin plates and a cold and hot air device, wherein the furnace base comprises a front base, a back base and a left end sealing plate; each air cabin plate is arranged between the front seat and the back seat of the furnace base; a corresponding air cabin is formed between the front and back seats of the furnace base and a corresponding air cabin plate and a corresponding sealing plate; a space between each wall body of the hearth body and the combined fire grate mechanism forms a corresponding main combustion chamber and a secondary combustion chamber; hot air entering the air cabin through the cold and hot air device passes through the combined fire grate mechanism and enters the main combustion chamber so as to play a role in drying the domestic garbage and assisting combustion; the middle part of the left side wall of the hearth body is provided with a secondary air inlet; and air entering the secondary combustion chamber from the secondary air inlet can play a role in producing vortex flow and assisting combustion, so that complete decomposition of dioxin and other harmful substances at a high temperature is promoted and CO, C<+> and the like are burnt out completely at a high temperature.

Description

technical field [0001] The invention relates to a domestic waste incinerator, in particular to a domestic waste incinerator for controlling dioxin discharge and a method for processing domestic waste. Background technique [0002] At present, the harmless, reduction, and resource treatment of municipal solid waste has become the focus of attention of the country and the public. At present, the largest way to reduce the amount of domestic waste is incineration. However, due to the mixed state of domestic waste in my country and the complex components of domestic waste, if the smoke generated after incineration is not effectively controlled, it will cause serious secondary pollution. At present, the most harmful substance in flue gas is dioxin. The full name of Dioxin is: polychlorinated dibenzo-p-dioxin (PCDDs for short) and polychlorinated dibenzofuran (PCDFs for short), which are special organic substances with strong toxicity. compound. Dioxin is a representative of env...
