铝电解净化除尘器探讨

Discussion on aluminum electrolytic purifying

中国已经是全球最大的铝生产国和消费国,铝电解生产是高污染,高耗能,高排放的行业。除尘器是铝电解烟气净化工艺的关键设备,合理地选择除尘器的形式,不仅对于控制污染、保护环境有重要作用,而且对于提高设备处理含尘气体的能力,降低投资,也具有重要的经济意义。除尘器的工作温度,处理风量,入口含尘浓度,压力损失,操作压力等是除尘器选型的主要技术参数。综合优化各因素,除尘器的选型是在各项参数的技术指标范围内,达到投资低,除尘效率高,运行稳定,维护方便,使用寿命长,操作管理容易的组合。

China is already the world＇s largest aluminium producer and consumer of aluminum electrolysis production is highly polluting, energy intensive and highly polluting industries. Dust collector is the key to aluminium electrolysis fume purification equipment, reasonably select filter form, not only have important role to control pollution, protect the environment, and to improve the ability of dust gas handling equipment, reduce the investment, also have important economic significance. Precipitator working temperature, air volume, entrance dust concentration, pressure loss, operating pressure and so on are the main technical parameters of the precipitator. Integrated optimization of various factors, filter selection is within the scope of the technical indexes of various parameters, achieve low investment, high dust removal efficiency, stable operation, easy maintenance, long service life, the combination of operation management easy.
