The invention relates to the means of cleaning gases from dust and chemical impurities in a layer of mechanical foam formed by dispersing a liquid with a stream of gas being processed, and can be used in various industrial areas where it is possible to use wet-type apparatuses

The purpose of the invention is to reduce the hydra i i .i secKoro resistance

The sloping side of the blade is evenly attached to the inner surface of the exhaust pipe around the circumference of its section. In this case, the blade plane provides an angle of 35-45. with a tangent to the circumference of the sec- enr1 of the exhaust pipe at the point of its intersection with the blade plane.

Such multidirectional movement causes intense dispersion of droplets and films and the formation of a suspended foam layer with a highly developed contact surface, in which gas treatment is required. The treated gas enters the separator 6, where it is expelled from the remaining moisture in it and is removed through the nozzle 7 from the device.
