Embodiment 2）

[0078] See figure 2 , the rest are the same as in Embodiment 1, except that the domestic waste incineration and flue gas treatment system of the present invention also includes a waste heat boiler 81 and a hot air preparation system. The air outlet of the hot air preparation system communicates with the air inlet of the two-way air supply main pipe of the cold and hot air device.

[0079] The hot air preparation system includes a heat exchanger 82 . The waste heat boiler 81 and the heat exchanger 82 are arranged in airtight series between the flue gas settling chamber 72 and the medium-temperature semi-dry neutralization reaction tower 91 through the third high-temperature flue 11-3. The third high-temperature flue 11-3 includes the front-stage flue gas Road 11-3-1, middle section flue 11-3-2 and rear section flue 11-3-3.

[0080] The right smoke outlet of the flue gas settling chamber 72 is airtightly connected with the left smoke inlet of the waste heat boiler 81 through ...

Abstract

The invention discloses a household garbage incineration and flue gas processing system and a method for processing household garbage. The system comprises a household garbage incinerator, a draught fan, a chimney, a high-temperature flue and a low-temperature flue. The key point is that the system also comprises an ultrahigh-temperature cyclone dust collector, a flue gas settling chamber, an intermediate-temperature semidry neutralizing reaction tower, an activated carbon ejector and a bag-type dust collector. The main combustion chamber and secondary combustion chamber of the household garbage incinerator allow dioxin and other noxious substances to be decomposed completely at the high temperature; the ultrahigh-temperature cyclone dust collector and the flue gas settling chamber can remove fly ash, dust, heavy metals, and precursors, carriers and catalysts, which are likely to form dioxin, such as C and Cu; the intermediate-temperature semidry neutralizing reaction tower can remove precursors such as chloride ions, which are likely to form dioxin; and harmful substances such as dioxin are removed by utilizing the activated carbon ejector and the bag-type dust collector, so that the discharge of the dioxin harmful substances is less than 0.1 ng / m<3> finally.

Description

technical field [0001] The invention relates to a domestic garbage incineration and flue gas treatment system, in particular to a domestic garbage incineration and flue gas treatment system for controlling dioxin emission and a method for treating domestic garbage. 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 wi...
