Cleans gas by washing it with liquid: acid gases, aerosols and dust are captured and neutralised in a three-level spray system.
A mixture of acid gas, aerosol and dust enters the lower section of the tower through the inlet duct and rises upwards. Liquid carrying the washed-out pollutants collects in the tower sump.
Each level has a spray header with nozzles. The rising gas passes through three liquid curtains in turn: at each one, part of the pollutants is absorbed into the liquid.
At each level, 18 nozzles spray the liquid in a cone. The finer the droplets, the larger the contact surface with the gas — and the more effective the cleaning.
At the top, a mist eliminator catches liquid droplets carried by the gas — otherwise they would reach the fan, the stack and the atmosphere. The cleaned gas leaves through the outlet pipe.
A motor-driven fan draws the gas out of the scrubber and discharges it through the exhaust stack to the atmosphere.
The pump delivers liquid from the tank up the riser to all three levels. Liquid collected in the tower sump returns to the tank through the drain — the water circulates continuously.
A dosing pump adds reagent to the tank, while a pH sensor continuously monitors the liquid. Acid gases are neutralised in the alkaline liquid.
Send us the gas composition, flow rate and temperature — an engineer will select the material, number of levels and reagent.
