Researchers distinguish three types of wet air scrubbers applied for the removal of particulate pollutants in the chemical industries providing proper air pollution control. The thing is that air treatment devices such as scrubber systems are considered to be essential for chemical process industries.
To be more precise, wet scrubbers are devices for air pollution control that are applied to provide health and safety resulting in the product’s recovery. All scrubbers are distinguished into two categories: wet air scrubbers and dry systems. Herewith, the wet type is regarded as the ideal option for numerous industries because wet scrubbers offer a high level of efficiency.
Wet air scrubbers catch particulate pollutants and remove them applying a special liquid or just water from a contaminated gas stream. A chemical additive is used in the water so that these pollutants react with it transforming them in a less dangerous compound. It should be noted that sodium hydroxide, or caustic (NaOH) is a widely used chemical in the solution for scrubber systems.
Additionally, some industries prefer using simple water as a solution for air treatment by wet scrubbers without the application of chemical reagents. Nowadays there are three main types of wet air scrubbers employed in the chemical process industries: jet venturi fume scrubbers, packed bed scrubber systems, and high-energy jet ventures. Herewith, each design of wet scrubbers is suitable for certain fields of application.
For instance, the jet venturi scrubber is considered to be the most basic air pollution control system. The operating principle is based on the liquid solution that passes through a nozzle and increases while the pressure decreases to atmospheric conditions. Thus, an area of low pressure appears that involves the gases into the head of the scrubber system.
Then the two-phase mixture is limited in the converging nozzle, and the two liquids are mixed in the throat of the wet air scrubber, while the solution immerses the gaseous particulate pollutants. “The clean fluid then increases to a gas through the diverging area, slowing as it achieves the outlet.”
The fact that most applications of wet scrubbers have a high level of noncondensable vapors makes the jet scrubber to discharge the stream into a separator tank. This tank has a pretty big size that allows for put the two-phase solution with sufficient residence time to enable the gaseous phase to separate from the liquid stage.
Finally, the jet venturi scrubber is perfect where a bulk removal is required due to benefits provided such as the cocurrent flow and intimate contact between the phases. The air treatment of huge volume is the reduction of most particulate pollutants exiting the wet air scrubber system.
Optromix is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.
