所谓干吸收就是在现行的行之有效的袋式过滤系统中去除废铝熔炼烟气中对环境污染的粉尘和各种无机物,以使排入大气的气体达到环保法规与条例规定的所有污染物排放标准要求。废铝在熔化过程中排放的污染物可分为三类:颗粒物:金属或矿产品的细微颗粒物、碎末、粉尘等;无机物:各种酸性物质、二口恶英;有机物:没有燃烧的碳氢化合物和一氧化碳。前两种污染物可在布袋收尘系统中清除干净,现在几乎所有的大型废铝再生企业都有这类环保设施,但发展中国家的中小型再生铝厂有这类环保系统的却很少。颗粒物可通过物理法去除,而无机物的去除则可向
The so-called dry absorption is in the effective bag filter system to remove waste aluminum smelting flue gas dust on the environment and a variety of inorganic substances in order to make the gas into the atmosphere to meet all the environmental regulations and regulations of pollution Emission standard requirements. Pollutants discharged from the aluminum scrap during melting can be classified into three categories: Particulate matter: Fine particles, ground dust, dust, etc., of metals or minerals; Inorganic matter: Various acidic substances, dioxin; Organics: Hydrocarbons and carbon monoxide. The first two types of pollutants can be removed in the bag-dusting system, and almost all large-scale waste-aluminum recycling companies now have such facilities, but there are few such small and medium-sized renewable aluminum plants in developing countries . Particulate matter can be physically removed and inorganic matter removed
