我厂氧化铝和水泥回转窑生产过程中,排出大量含有色金属和碱的烟尘,为了回收这些有用物质和减少其对大气的污染,采用了机械收尘装置和电收尘器。电收尘器的供电过去是采用Aφ—18型机械整流器,此种整流设备的电力消耗大,收尘效率低。为了 During the production of alumina and cement rotary kilns in our factory, a large amount of smoke and dust containing non-ferrous metals and alkali was discharged. In order to recover these useful substances and reduce their pollution to the atmosphere, a mechanical dust collector and an electric precipitator were adopted. Electric dust collector power supply used in the past Aφ-18 type mechanical rectifier, such rectifier equipment, power consumption, low efficiency of dust collection. in order to
