Spray tower, as a new type of spray absorption equipment, has been widely used in the purification of waste gas. The concept of the fluidized bed is developed into the vapor liquid mass transfer equipment, so that the filling material in the spray tower is in a fluidized state, so that the mass transfer process can be enhanced. His features are: high gas speed, high processing capacity, light tower, the steam distribution is relatively uniform, is not easy to be blocked by solid and viscous materials. Especially due to the tower the turbulence intensity, so the mass and energy transfer can be enhanced. Therefore, it can greatly reduce the diameter of the column, reduce the height of the tower. The tower processing air flow is big, empty tower gas speed of 1.5 ~ 6.0m/s, spray density of 20 ~ 110m3/ (M2 - H), the pressure loss of 1 500 ~ 3 800pa, turbulent ball tower in addition to spray device with swirl plate demister, by passing air through the tower plate to produce rotary motion, using centrifugal force to the role of the mist removing, in addition to its mist efficiency can reach 98% - 99%, and the structure is simple pressure smaller. Turbulent ball tower for a variety of corrosive gases purification treatment effect is obvious, can effectively remove the hydrogen chloride gas (HCl), hydrogen fluoride (HF), ammonia (NH3), sulfuric acid mist (H2SO4), chromic acid mist (CrO3), hydrogen cyanide gas (HCN), alkali vapor (NaOH), hydrogen sulfide (H2S), formalin (HCHO) etc. water soluble gas.
