Wet air scrubbers: types and operating principles

A wet scrubber is an air treatment filter for purification from mechanical pollutants. Two main types of air pollution control equipment are used to solve the problems of air treatment from dust and gas emissions of industrial enterprise – dry or wet scrubbers for capturing and removing solid particulate pollutants. 

Dry scrubber systems of inertial, gravitational, electrostatic, and acoustic (ultrasonic) types are widely applied in industry, however, in several real production conditions, they significantly lose inefficiency to wet air scrubbers. Indicators of air treatment presented by scrubber systems that retain and dispose of solid particulates by liquids often reach 99.9%. 

The benefits of wet air scrubbers include the ability to remove complex dust and gas emissions, operation with hot suspensions, explosive, and fire-hazardous solid substances in the vast majority of industries. The operating principle of all existing wet scrubbers is based on the capture of solid particulate pollutants contained in the dusty air by drops, followed by the removal of the collected sludge. 

The efficiency of scrubber systems depends on the method of contact of the solids and liquids, the size, density, wettability, and other parameters of the particles. The simplest wet air scrubbers are structurally similar to dry scrubber systems, differing from them only by supplying irrigation fluid and removing sludge. 

Most effective wet scrubbers have a more advanced design that defines specific classes of devices. The advantages of wet air scrubbers include the following features:

  • Efficiency up to 99% for dust particulates with sizes from 0.5 microns;
  • Ability to work in explosive and fire-hazardous environments, as well as in hot dust streams with temperatures up to + 900 degrees Celsius;
  • Universality;
  • Low pneumohydrodrives, ease of implementation;
  • Low capital and operating costs, high price availability of wet air scrubbers even for medium-sized and small companies, fast payback of air treatment systems.

If you search for the best air treatment device to improve air quality, you can buy a high-tech completely new type of wet scrubber – a Multi-Vortex wet air scrubber produced by Redwood Technology.

Redwood technology 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.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at info@rdwd.tech
