Scrubbers (gas cleaning devices) are a device whose principle of operation is based on flushing gas (steam) with a liquid. The gas fraction is washed with water or other technological solution, during mixing and interaction of which the process of cleaning gases from impurities and suspensions takes place. This mixing principle is called the "wet cleaning" method, which allows you to clean the gas fraction from particles of any size. Wet cleaning devices use different types of surfaces when mixing liquid with a gas fraction (irregular nozzle). The use of this method involves the removal of all impurities from the gas fraction, due to condensation of heavier vapor particles on them. The disadvantage of this cleaning method is the formation of a large amount of sludge, the advantage is the relatively low cost of "wet" cleaning devices.
