目前我国冶金、机械等行业广泛采用五吨左右的电炉炼钢。在冶炼过程中,随着冶炼钢种类不同,使用的废钢及造渣原料也有差别,吹氧量的大小也有各异,所以电炉发生的烟气,从它的物化性能看也各不相同,即使是同一座电炉在其不同的冶炼期,所产生的烟气量大小、物化性能、排出烟气的位置也互有差异。 由于电炉在冶炼过程中产生大量的烟气,不仅污染了环境,而且直接影响操作工人的劳动条件。近几年来,各地有关企业对电炉除尘大都开始采取措施,但由于受炉顶
At present, China’s metallurgy, machinery and other industries widely used five tons of EAF steelmaking. In the smelting process, with the different types of smelting steel, the use of scrap and slagging raw materials are also different, the size of the amount of oxygen are also different, so the furnace flue gas, from its physical and chemical properties are different, even if Is the same electric furnace in its different smelting period, the amount of flue gas generated by the physical and chemical properties, the location of flue gas emissions are also different from each other. As the furnace in the smelting process produces a lot of flue gas, not only pollute the environment, but also directly affect the working conditions of workers. In recent years, the relevant enterprises around the electric furnace dust mostly started to take measures, but due to the roof
