袋式收尘器在卡尔多炉烟气净化上的应用

目前,就我国烟气排放标准而言,电除尘仍是治理燃煤有色金属冶炼锅炉烟尘的首选方法。但是,由于电除尘器的收尘效率受粉尘性质的影响较大,而我国的燃煤成分又千变万化,粉尘性质各不相同,因此,许多冶炼厂难以实现在燃煤有色金属冶炼锅炉上长期、高效、稳定地使用电除尘器[3]。随着国家对粉尘排放指标的提高,布袋除尘器适应性强、除尘效率高、运行可靠等优点逐渐显现出来。布袋除尘器是能够有效控制烟尘污染的主要设备之一,它具有很高的除尘效率。经过布袋除尘器过滤后的烟气含尘质量浓度一般都低于50mg/m3,同时还能有效地除去烟气中的微细粉尘。在我国,布袋除尘器已在冶金、建材、化工、筑路等行业中广泛应用。

The Application of Bag Filter on Fume&Gas Cleaning of Kaldo Furnace

According to the current emission standard in China,electric precipitation is still the preferred method for non-ferrous metal smelting industry.However,as the dust performance has a big influence on the efficiency of electric precipitation and the composition of fire coal is variable,many metallurgical refineries can not have long term stable electric precipitation efficiency and performance.As the national emission standard becomes increasingly requiring,the strong adaptability,high efficiency,stable operation and other advantages of bag filter are gradually discovered.Bag filter is one of the main equipments in fume pollution control,which is of high efficiency.The dust concentration after bag filtration is usually less than 50mg/m3 normally,and the small particle can also be removed at the same time.In our country,the bag filter is used widely in metallurgy,building materials,chemical industry and road building
