Spray tower

A spray tower is a type of air pollution control device that removes contaminants from a gas stream by spraying it with a liquid, typically water or an alkaline solution. The liquid droplets capture and neutralize pollutants through absorption or chemical reactions.

Technical Points:
Mechanism: Gas is directed through the tower and is sprayed with liquid droplets, which absorb or neutralize pollutants like gases, aerosols, or particulate matter.
Design: Gas flows vertically while the scrubbing liquid is sprayed from the top through nozzles or spray systems.
Efficiency: Effective for removing gases and aerosols, but less efficient for fine particulate removal compared to other scrubber types.
Applications: Used in industries such as chemical manufacturing, power generation, wastewater treatment, and incineration.
