Guide to Industrial Scrubbers & their Role in Industrial Applications

Air pollution control is one of the main concerns of business owners across industries where toxic gases, particulates, and chemicals are produced as a byproduct of manufacturing. There are several ways of achieving pollution control. The utilization of industrial scrubber systems is one of the most popular methods of pollution control. These systems are developed to remove particulates, toxic gases, and other chemicals from exhaust gas streams. What are the different types of scrubbers used in industrial processes?

Important Types of Scrubbers in Industrial Processes

Industrial scrubbers remove the toxic substances and fumes from gas streams by washing these substances or neutralizing them. Based on their purpose and construction, these scrubbers are differentiated into two types:

Industrial Wet Scrubber System

  • Wet Industrial Scrubbers: This is one of the most basic types of scrubbers used in industrial processes. In these scrubbers, contaminated or toxic gas is made to pass through a composite container that has water in it. The water absorbs the contaminants during the process. Other liquids are also used to remove pollutants, and their chemical composition, and charges differ based on the application.
  • Reverse Industrial Scrubber

  • Dry Industrial Scrubbers: These industrial scrubbers do not require water to absorb gases, rather they feature a reaction center with a dry reaction material. All contaminants in the polluted gas stream are absorbed by the dry reaction material or sorbent, as it is popularly known as. The system also features a material component, which perfectly removes any dry sorbent found in pollutant. For instance, dry scrubbers are also used to remove acids found in toxic gas streams.

What are Different Types of Industrial Scrubbers & their Pivotal Roles in Pollution Control

As discussed before, wet industrial scrubbers are one of the important types of scrubbers used in industrial processes. The following are a few popular types of industrial wet scrubbers used in different industrial applications.

  • Venturi or Particulate Scrubbers: The scrubber system derives its name from a Venturi-shaped chamber or Venturi scrubber. The scrubber uses water, typically recirculated water, as a scrubbing fluid. The gas stream is made to pass through the chamber, where the water atomizes and captures the pollutants.
  • Cyclone Spray Chambers: This scrubber system combines water spray and moving air or cyclone to capture pollutants. Available in different liquid particle sizes, you can choose small particle sizes because cyclonic motions help reduce the particle size.
  • Spray Towers: In this type of scrubber, the exhaust streams are made to pass through the spray tower. There are nozzles in the chamber to spray the gas. Like cyclone spray chambers, these spray towers are also available in different liquid particle sizes. You can easily choose the size that meets your requirement.
  • Orifice: This equipment is much similar to the Venturi scrubber; the only difference is the gas enters into a narrow section, where it passes through a pool of water or scrubbing liquid used. This scrubber requires less amount of water for recirculation and does not require much water or energy, too.
  • Impingement: This is one of the important variants of orifice, where the cleaning liquid is placed in the perforated tray.

In addition to the above discussed, there are several more types of scrubbers used in industrial applications. These scrubbers are mainly designed for atmosphere and local cleansing as well as fume abatement. Owing to their important roles, it becomes imperative to source them from a reliable manufacturer or supplier.
