三、火法精炼生产光亮铜杆的环境保护火法精炼采用的COS-MELT倾动炉的炉子内一般为微负压,生产过程中产生的精炼烟尘尾气,以及加料口、扒渣口、出铜口的集尘罩收集的烟气,从后燃烧室、沉淀室到废热锅炉,然后进入烟气处理系统,整个烟气处理系统靠变频电机控制风量。烟气出口温度1130℃,燃烧室约为800℃～900℃,沉淀室为700℃～880℃,通过废热锅炉(或风冷),到收尘室温度要降到120℃。
Third, the fire refining the production of bright copper rod environmental protection Fire refining COS-MELT tilting furnace used in the furnace is usually a slight negative pressure, the production process of refined soot exhaust, and feeding port, slag mouth, out of copper The flue gas collected by the dust collecting hood at the mouth flows from the afterburning chamber to the waste heat boiler and then enters the flue gas treatment system. The flue gas treatment system controls the air volume by the variable frequency motor. Flue gas outlet temperature 1130 ℃, the combustion chamber is about 800 ℃ ~ 900 ℃, the precipitation chamber is 700 ℃ ~ 880 ℃, through the waste heat boiler (or air-cooled), to the dust chamber temperature dropped to 120 ℃.
