SCRUBBER Russian patent published in 2015 - IPC B01D47/02 

FIELD: machine building.

SUBSTANCE: scrubber comprises a leakproof casing 1 with inlet 2 and outlet 3 branch pipes. The leakproof casing 1 is divided into an inlet chamber 5 and an outlet chamber 6 by a leakproof partition 4 from inside. The inlet branch pipe is mounted on the wall of the inlet chamber 5 and tangentially to it, i.e. the inlet branch pipe 2 axis is parallel to the tangent line to the cylindrical surface of the leakproof casing 1. The lower part of the outlet chamber 6 is filled with fluid. The outlet branch pipe 3 is mounted on the outlet chamber 6 wall in its upper part above the fluid level. The outlet branch pipe 3 is installed perpendicularly to the outlet chamber 6 wall, in our invention the outlet branch pipe 3 axis is located along the radius of the cylindrical surface of the leakproof casing 1. The first de Laval nozzle 7 and the second de Laval nozzle 8 are placed sequentially along the same axis inside the leakproof casing 1. Both de Laval nozzles are connected to each other in a leakproof way and so that the outlet of the first de Laval nozzle 7 is the inlet of the second de Laval nozzle 8. Both de Laval nozzles inside the leakproof casing 1 are fixed in the hole of the leakproof partition 4. The outlet of the second de Laval nozzle 8 is immersed in the fluid filling the lower part of the outlet chamber 6. The common axis of first de Laval nozzle 7 and the second de Laval nozzle 8 does not coincide with the axis of the inlet branch pipe 2.

EFFECT: improved gas flow scrubbing.
