Flue gas desulfurization and dust removal equipment is widely used, can be wet dust removal, wet desulfurization, but also dust removal and desulfurization integration, not only suitable for coal-fired circulating vulcanization bed boiler dust removal and desulfurization, but also can be applied to coal-fired chain boiler wet desulfurization and dust removal and flue gas purification, high efficiency of sulfur dioxide removal, exhaust gas purification. It is used in the furnace industry to remove radon fluoride and acid exhaust gas purification equipment of kiln tail gas, and desulfurization of pellet and sintering machine tail gas. The waste ammonia water purification efficiency of desulfurizer is extremely high, and the original flue gas SO2 is 11000mgm3. It can be removed below 120mg/m3 and is widely used in the field of pellet flue gas in steel mills. It is a kind of low resistance and high efficiency wet dust removal desulfurization equipment and a novel environmental protection product for desulfurization equipment.

　　Dust collector is used to remove harmful dust in the gas equipment, on this basis to increase the desulfurization effect, is the desulfurization dust collector. Desulfurization dust collector is generally wet desulfurization dust collector, wet desulfurization dust removal with water film desulfurization dust removal, impact water bath desulfurization dust removal and so on. The advantage of wet dust removal is that it is easy to maintain, and it can achieve the effect of dust removal and desulfurization (nitrogen removal) at the same time by preparing different dust removal agents. The disadvantage is that the dust removal liquid needs to be treated, which may lead to secondary pollution. After years of improvement, it has developed various types of water film desulphurization dust collector, such as Churi type, swirl plate type, swirl column type, float ball type, sieve plate type, equipment technology is becoming more mature, each has its own advantages and disadvantages, enterprises can choose different types according to their own needs.
