METHOD FOR SEPARATING ANTIMONY MERCURY FROM FLUE GAS GENERATED BY ANTIMONY MERCURY ORE SMELTING

摘要

Disclosed is a method for separating antimony mercury from flue gas generated by antimony mercury ore smelting which belongs to the field of metallurgy. The method adopts a high temperature resistant bag dust collector or a dust collection device combined by a cyclone dust collector with a high temperature resistant bag dust collector to perform dust collection treatment of flue gas generated by antimony mercury ore smelting at high temperature. Solid antimony oxide powder in the flue gas is captured by the bag dust collector or the dust collection device combined by a cyclone dust collector with a bag dust collector and thus is separated preferentially. Mercury steam exists in gas state in the flue gas treated by the cyclone dust collection or bag dust collection. Therefore, the purpose of separation of solid antimony oxide powder form gaseous mercury steam is reached. The method can reach an antimony mercury separation rate of up to more than 90% and has the advantages of simplicity, practicality, and less environmental pollution.
