Research And Application Of Efficient Dust Removal And Cooling Of Smelting Gas

At present, smelting gas purification mainly adopts wet cleaning and countercurrent contact method at home and abroad to achieve the effect of purification and cooling. Affected by technology, materials and so on, its equipment is large which covers a huge area and cleaning and cooling ability is limited. With smelting system capacity increasing, the burden of purification process of acid system is increasing. According to observation of Jinchuan company acid system, the increase of the smoke gas causes the clogging of packing, nozzle and perforated strainer plate inside the equipment and the serious mud at the bottom of the tower, which not only reduces dust removal and cooling effect of the equipment, but also increases the labor intensity of the staff and maintenance difficulty. This article shorten the process, improve washing effect, reduce the area, and save the investment at the same time through the reforming and optimization of the internal structure and configuration purification of the turbulent tower, washing tower and electric demister of purification process, which has very high promoting significance in high dust smelting gas sulphuric acid system.
