The air pollution control system captures contaminated exhaust gas from the source through ductwork connected to a centrifugal blower. The blower draws the gas into the scrubbing tower where it passes through multiple stages of gas-liquid contact. Water and chemical reagents are sprayed counter-currently to absorb and neutralize pollutants. The system uses gas detection sensors to monitor outlet emissions in real-time, with the PLC controller automatically adjusting scrubbing liquid flow, blower speed, and chemical dosing to maintain compliance. A mist eliminator removes entrained droplets before the clean gas exits through the stack. The spent liquid is collected in a sump, treated, and recirculated to minimize water consumption and waste generation.
