在生产工业硅的 PKO-16.5KpH1电炉上安装了水冷式低位排烟罩,其安装高度与电极夹持器水平高度相等,而导线装在套管里。这种低位排烟罩的结构特点是:在电极夹持器通过罩盖的地方加做密封;罩盖上设有7个通加料管的孔。利用烟罩侧面上的4个支管排烟。排烟罩的盖是由数片水冷水套组成,但其中间部分由混凝土制成。烟罩内部工作表面涂以高铝涂料保护层,烟罩的高度为2.4m、直径(外
A water-cooled low exhaust hood is installed on the PKO-16.5KpH1 electric furnace for industrial silicon, which is mounted at a level equal to the level of the electrode holder, with the wires in the bushing. The structural features of such a low smoke exhaust hood are as follows: the electrode holder is sealed at the place where the electrode holder passes the cover; and the cover is provided with seven holes for feeding the material. Use 4 branch pipes on the side of the hood to smoke. The cover of the hood consists of several pieces of water-cooled water jacket, but the middle part is made of concrete. Fume hood working surface coated with high aluminum coating, hood height 2.4m, diameter (outside
