One of the biggest challenges environmental engineers face is devising new techniques to prevent additional air pollution. The industry is a large contributor to air pollution. Scrubbers are used at coal-burning power plants, asphalt/concrete plants, and a variety of other facilities that emit sulfur dioxides, hydrogen sulfide, and gases with high water solubility. The work of a typical scrubber is based on a process in which drawn through a mist of water made by spray nozzles, then through separators, where water droplets with dust and particles are removed. The main principle of wet air scrubber operation is that the upcoming dust has to be wetted to add weight/mass to each particle so that it can be removed in what is fundamentally a cyclonic separator, baffled chamber or similar device. The liquids are atomized via a fixed venturi or spray nozzles which attracts the particles. A mist type separator is used to separate them from the air stream. Aerosol and gaseous pollutants in an air stream are removed by absorption or chemical reactions with the water solution. Sometimes the mist is injected with limestone powder to help extract the dirt particles. Wet air scrubbers are often used for corrosive, acidic, or basic gas streams. A collected waste (slurry) is discharged at the bottom of the scrubbers in a liquid form and disposed of separately. The resulting pollutant-laden wastewater is processed into sludge, which is used to make bricks. Wet air scrubbers can be used in a wide range of applications including high temperature.
Wet scrubber is an air treatment system which uses water to separate the collected dust or fume from the air stream. There are many types of dust control equipment, but we here at Optromix can help you choose the right system for your specific situation. The selection of the type of scrubber is based on a number of important factors. With our experience, we can audit your site and existing plant to help you work out the best equipment to meet your requirements.
Wet scrubbers are an effective air pollution control devices. To effectively work, many variables are considered when designing. Most commonly, a wet scrubber consists of a vessel, ductwork, fan, mist eliminator, pumps, and the liquid treatment.
Being a new type of wet air scrubber, multi-vortex wet air scrubber provides improved air treatment quality and can be used for both particles matter and gas collection. The treatment quality of multi-vortex wet air scrubber is generally 99.95-99.99% for both types of pollutants. Besides high efficiency, multi-vortex wet air scrubber possesses a number of advantages over conventional wet scrubbers – multi-vortex wet air scrubber is compact, omnivorous, eco-friendly, economical, and low-maintenance.
