Flue gas purification device for incineration of household garbage

Abstract

The invention discloses a flue gas purification device for incineration of household garbage. The device comprises a reaction tower and a bag type dust collector, wherein an exhaust fan is connected between the reaction tower and the bag type dust collector; a gas inlet is formed in the lower side of the reaction tower, a gas outlet is formed in the upper side of the reaction tower, a gas flow channel with an upward flow direction is formed between the gas inlet and the gas outlet, and a sprayer with a downward opening is fixedly mounted at the top of the reaction tower; and a plurality of dust collecting regions are arranged inside the bag type dust collector, a filter screen is mounted between every two adjacent dust collecting regions, and adjacent filter screens are distributed at intervals up and down. Through the mode, the device disclosed by the invention can be used for fully purifying and then discharging the polluted flue gas produced by incineration of household garbage, thereby greatly reducing the environment pollution caused by incineration of household garbage.

Description

technical field [0001] The invention relates to domestic waste treatment equipment, in particular to a flue gas purification device for domestic waste incineration. Background technique [0002] At present, common domestic waste treatment methods mainly include landfill, thermal decomposition, etc. Among them, landfill treatment will not only occupy a large amount of land resources, but also produce waste gas, waste water, etc. to pollute the air and groundwater. Therefore, this simple treatment method It is basically no longer used. Compared with landfill, incineration is a better treatment method. After the garbage is processed by incineration, it is convenient for landfill, saves land, can also eliminate various pathogens, and convert toxic and harmful substances into non-toxic. However, there are still a lot of household wastes that are directly burned in the open air, and the smoke is directly discharged into the atmosphere, which is likely to cause environmental deteri...
