Reduce the amount of smoke and improve the technical level of production operations. Improper handling techniques are the main cause of the increase in smoke volume. The problem with most manufacturers is that the electric furnace structural parameters do not match. Industrial silicon smelting is carried out continuously under the submerged arc state of the electric furnace. The operation should be closed and the ratio of the resistance of the charge to the current and voltage should be adjusted. The choice of flue gas purification equipment. Smelting one ton of industrial silicon produces about 2000-2600M3 of flue gas. After burning through the furnace mouth, a large amount of cold air is mixed. The silicon micropowder stays in the air for a long time, is not easy to settle, the specific resistance is large, the silicon powder is oily, and the viscosity increases with temperature.
Purification principle. Fully burned using a spark trap. Collect unburned carbon particles with sparks eliminates the possibility of spark burning the filter bag. Some coarse particles are separated in the cyclone to reduce the amount of dust. The temperature is lowered by the heat exchanger to reduce the viscosity of the silicon dust, and then sent to the bag filter by the fan, the silicon dust is filtered in the bag, and the filtered pure gas is emptied.
