In general, wet scrubbers achieve a higher level of pollutant removal than dry scrubbers. Any industries that produce air pollutants might use wet air scrubbers of various designs and construction.
Wet scrubbers work by absorbing pollutants with water or a water-based solvent. In the wet scrubber, the contaminated gas enters at the bottom and passes upward through the packed bed and downward-flowing solvent sprays. The pollutants are collected in the solvent droplets, and before the gas leaves the scrubber, it passes through a mist eliminator to capture any droplets. Contaminated gas moves through the solvent. As it does, the solvent absorbs the contaminants, and the scrubber releases clean gas.
A positive, negative or neutral charge will allow the solvent to bind with different inorganic pollutants. Some of the most common wet scrubber solvents include:. As the solvent absorbs contaminants, new solvent is necessary to purge the pollutants and replace the evaporated liquid. Solvent flooding can be either continuous or periodic.
Low-energy scrubbers can remove large particles, while high-energy scrubbers can remove the tiniest particles. All wet scrubbers, whether high or low energy, have a mist eliminator component.
The mist eliminator collects and removes the contaminated droplets from the solvent. An effective mist eliminator is a fundamental component of any wet scrubber.

When determining whether to use a wet scrubber, facility managers should consider which air pollutants their processes generate and the potential dangers those contaminants pose. Wet scrubbers are effective for removing a wide range of different air pollutants. A wet scrubber can control specific airborne pollutants. Industries that produce such pollutants should consider using wet scrubbers to minimize environmental impact and human safety risks.
They can help reduce any of the following air pollutants. Many industries use wet scrubbers to control airborne fumes, vapors and gases. These inorganic pollutants can cause environmental disruption and adverse health effects if they enter the atmosphere in large quantities. The inorganic gases a wet scrubber can remove from the air include some of the most harmful air pollutants, as designated by the Environmental Protection Agency.
Some of the most common such pollutants include:. A wet scrubber can also remove volatile organic compounds from the air. VOCs are human-made chemicals produced during specific manufacturing processes, especially those used to make paint, pharmaceuticals and refrigerants.
They become trapped in specific solids or liquids and release into the air over time. Some VOC chemicals can cause severe short and long-term health effects. The manufacturing of the following materials release VOCs:. Other air pollutants include particulate matter, which encompasses a wide range of solid particles and liquid droplets.
While some are large enough to see with the naked eye, others are minuscule. PMs can be as large as 10 micrometers and as tiny as 2. For perspective, a strand of human hair is generally about 50 to 70 micrometers in diameter, which is 30 times larger than the tiniest PM particle. PMs can include any of the following, given a size of 10 micrometers or smaller:.
Since PMs are so diverse, their sources and hazard levels vary. Some PMs can cause health issues if inhaled — if small enough, they can even enter the bloodstream. In large quantities, PMs can cause haziness and reduced visibility.
Because of these negative effects, regulating PM quantity is a crucial aspect of air pollution mitigation. Wet scrubbers can help remove PMs from the air. Another technique that can be used with wet industrial scrubbers involves the exhaust gas being forced to bubble through a sizable pool of the scrubbing liquid. When this occurs, the contaminants are left behind in the scrubbing fluid. Because of how similar these designs are, the structures of most wet industrial scrubbers are the same.
A fan system will combine with basic ductwork to send the gas through the chambers and to the exhaust vents. A collection area is also included for the scrubbing liquid and any pollutants that have been caught. Because of the content of this liquid, you will be required to dispose of the waste via special methods. Dry scrubbing systems are used in the majority of modern plants and are notable for being able to get rid of pollutants and contaminants in exhaust gas without creating a wet sludge.
While dry scrubbers purify the gas with dry substances, these systems work almost exactly like wet scrubbers. Before the exhaust gas stream leaves the scrubber chamber, the weightier pollutants will fall down and be caught within a particle screen.
These scrubbers are mainly used to eliminate acidic substances like hydrochloric acid from various combustion sources. You should use these scrubbers because they are highly advantageous to the environment. Even though these scrubbers are able to get rid of most pollutants from exhaust gas, they create very little waste material when compared to wet scrubbers, which also removes the hassle of needing to dispose of wet waste material.
