The invention discloses a waste gas treatment device for desalting pretreatment of household garbage incineration fly ash. The waste gas treatment device comprises a waste gas primary filtering mechanism, a gas conveying pipeline and a purification treatment box, the lower end of one side of the waste gas primary filtering mechanism is fixedly connected with a waste gas inlet pipe, the upper end of the other side of the waste gas primary filtering mechanism is connected with the purification treatment box through the gas conveying pipeline, an electromagnetic valve is fixedly mounted at the lower end of the gas conveying pipeline, and a dust removal mechanism and a water washing desalting mechanism are arranged on the inner side of the purification treatment box. The dust removal mechanism, the water washing desalting mechanism and an exhaust mechanism are arranged in the purification treatment box, salt-containing waste gas separation and water-gas separation can be completed in sequence, and particulate matters, a large amount of soluble inorganic salt such as sodium salt, potassium salt and chlorine salt and harmful substances such as high-content heavy metal contained in waste gas can be fully treated.
Description
technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a waste gas treatment device for desalination pretreatment of domestic waste incineration fly ash. Background technique [0002] Domestic waste incineration fly ash is mainly collected in flue gas pipes, flue gas purification devices, cyclone separators and bag filters. Fly ash contains a large amount of soluble inorganic salts such as sodium salt, potassium salt and chloride salt, high content of Hg, Pb, Cd, Cu, Cr, Zn, Ni and other heavy metals, and high concentrations of highly toxic organic carcinogens such as dioxins. The fly ash of domestic waste incineration is defined as hazardous waste, and the fly ash must be stabilized and harmlessly treated. For example, the prior art patent No. 201110122176.0 discloses a municipal waste incineration fly ash treatment equipment, which includes a dust treatment chamber and a gas treatment chamber. The two ch...
