Conventionally, various methods have been used to reduce the emission of harmful fine dust discharged from the exhaust port of industrial facilities, but the concentration of fine dust in the atmosphere is increasing significantly as the days go by. In general, fine dust is defined as consisting of lumps of sulfate or nitrate formed by reacting air pollutants in the air, carbons and soot generated in the process of burning fossil fuels such as coal and petroleum, and minerals generated from soil dust on the surface. have. Among them, the most important factor in the generation of fine dust is the emission of carbon and soot generated in the process of burning fossil fuels such as coal and petroleum generated from industrial facilities. In general, as a method to remove or purify fine dust from the exhaust gas discharged from the exhaust of industrial facilities, a filtering facility such as a filter device or a dust collection facility using static electricity is used, but the removal efficiency of fine dust is greatly improved. There is not.
