With the continuous advent of a variety of high-efficiency wet dust collectors, high-efficiency wet dust collectors use screen tube water bath filtration, and the dust removal effect of the device is good. The existing atmospheric pollution sources in the metallurgical industry have been well controlled and treated. The purified gas in the dust removal device is finally discharged into the atmosphere through the dehydration discharge device. However, the environmental protection effect of the smoke exhaust in front of the furnace during the production of ferrosilicon alloy is poor. The smoke exhaust valve in front of the furnace selected in the early stage is not a high-temperature resistant valve. Affected by the high-temperature flue gas when the ferrosilicon alloy is taken out of the furnace, the valve is severely deformed, affecting the dust collection effect, and a small amount of smoke and dust overflows. Seriously affects the environmental protection dust removal effect. At the same time, there is smoke and dust pollution in the production area, and employees do not have a better working environment during production activities. Utility Model Content
