In today's society, with the continuous improvement of people's lives, people pay more and more attention to environmental protection. Now many industries develop or equip their own environmental purification systems according to their own industry characteristics, as the core component of ventilation and dust removal - dust removal In the case of different industries, different dust collectors are selected. Due to the characteristics of dense resources, intensive energy consumption and large scale of production, iron and steel enterprises have long been exposed to eavy emissions and serious pollution. Especially the electric steelmaking steel pollution is the most serious.
According to the conditions of steelmaking, when designing the dust collector to select the dust collector, we need to consider the temperature, gas properties, dust characteristics, so the bag filter can be well used in electric furnace steel dust removal. The reason is that electrostatic dust removal The device will have excessive resistance due to excessive furnace temperature, which will seriously affect the purification efficiency. The wet dust collector cannot be applied to the heavy steelmaking, because the steel dust in the electric furnace contains sulfides and nitrides. It is easy to produce sulfuric acid and nitric acid, which will cause corrosion of the wet dust collector.
The bag filter is currently the most suitable dust removal equipment for electric steelmaking. The bag filter has high dust removal efficiency, and the dust removal efficiency reaches 99%. It can capture fine dust particles with a particle size larger than 0.3 microns, which can meet strict requirements. Environmental protection requirements. The bag filter has simple structure, stable operation, less initial investment and convenient maintenance. It is a dust collector equipment for the electric steelmaking industry.
