二汽铸造二厂是一个生产汽车底盘毛坯的大型铸造厂,全厂配有70多台除尘设备。建厂初期,由于设计标准低,大多使用自制的湿式除尘器,排出的粉尘浓度远远达不到国家规定的排放标准。从1983年初起,该厂大搞技术改造,积极选用目前国内技术上较先进的微震反吹风扁布袋除尘 Two Steam Casting Plant is a production of automotive chassis rough large foundry, the whole plant with more than 70 Taiwan dust removal equipment. In the early stage of construction, due to the low design standards, most of them use self-made wet dust collectors, and the dust concentration discharged is far below the national emission standards. Starting from early 1983, the plant vigorously technological transformation, and actively use the current domestic technology more advanced microseismic blowback flat bag dust
