| titleOfInvention | A kind of cleaning treatment method of high arsenic fluorine-containing chlorine material |
| abstract | A cleaning treatment method for high-arsenic fluorine-containing chlorine materials, comprising: (1) reducing and smelting high-arsenic fluorine-containing chlorine-containing materials, reducing agents and fluxes after batching, to obtain sulfur matte, lead alloy, smelting flue gas and slag; (2) Mix the high-temperature smelting flue gas with air and then oxidize, and the obtained mixed flue gas is cooled and then electrostatically collected to obtain primary solid dust and primary arsenic-containing flue gas; Filter to obtain secondary solid smoke and secondary arsenic-containing flue gas; (4) quench the secondary arsenic-containing flue gas to collect arsenic to obtain arsenic trioxide solid and fluorine-chlorine flue gas (5) fluorine-chlorine flue gas is sprayed by sulfidation, Arsenic sulfide slag and waste liquid are obtained; the waste liquid is evaporated and crystallized to obtain a mixed solid containing sodium chloride and sodium fluoride. The invention realizes the clean emission of flue gas in the smelting process of high-arsenic, fluorine- and chlorine-containing materials without secondary pollution, and has the advantages of high efficiency, environmental protection, safety and the like. |
