How Wet Scrubbers Work to Remove Air Pollution
Wet scrubbers are devices that are commonly used to remove air pollution from industrial and commercial processes. They work by using a liquid to capture and remove pollutants from the air.
Here’s how wet scrubbers work:
Polluted air is drawn into the scrubber and passed through a series of liquid droplets or mist, which is typically water.
The pollutants in the air come into contact with the liquid droplets and dissolve into the water.
The clean air is then released from the scrubber and the water containing the dissolved pollutants is collected in a tank.
The water is then treated to remove the pollutants before being released back into the environment or reused in the scrubbing process.
The effectiveness of a wet scrubber depends on a number of factors, including the type of pollutant being removed, the concentration of pollutants in the air, and the type of liquid used in the scrubbing process. Different types of scrubbers are designed to remove specific types of pollutants, such as sulfur dioxide, nitrogen oxides, or particulate matter.
Wet scrubbers are an effective and widely used method for removing air pollution in many industrial and commercial applications.
What Are Wet Scrubbers?
Wet scrubbers are air pollution control devices that are used to remove various types of pollutants from industrial and commercial processes. They work by spraying a liquid, typically water, into a stream of polluted gas or air. Pollutants are attracted by the liquid droplets, which then pull them out of the gas stream.
Wet scrubbers can be used to remove a wide range of pollutants, including gases, particulates, and even odors. They are commonly used in industries such as power generation, chemical manufacturing, and food processing.
There are several types of wet scrubbers, each designed to remove specific types of pollutants. Some of the most common types include:
Venturi scrubbers – use a high-velocity liquid spray to remove particles and gases from the gas stream.
Spray tower scrubbers – use a spray nozzle to disperse liquid into the gas stream to remove pollutants.
A packing material, such plastic or ceramic, is used in packed bed scrubbers to improve the surface area for contact between the liquid and gas streams.
Cyclonic scrubbers – use centrifugal force to separate the liquid droplets from the gas stream, capturing pollutants in the liquid.
