DEVICE FOR DUST AND GAS CATCHING FROM SMOKE AND AGGRESSIVE GASES Russian patent published in 2009 - IPC B01D45/04 

FIELD: ecology.

SUBSTANCE: invention relates to field of control of atmospheric air pollution. Device contains cylindrical body with input and output branch pipes, bunkers for withdrawal of sedimentary particles and sludge, device for compressed air supply. Devices for compressed air supply placed in tangential manner to body are installed at angle 20°÷25° to the vertical in direction of purified gas flow movement and are made in form of hydrodynamic accelerators, which have axial branch pipe for supply of compressed air, tangential branch pipe for liquid supply, and output opening of accelerator made in form of Laval nozzle. Device is equipped with regulators of liquid and compressed air consumption, as well as with reservoir for chemical solutions.

EFFECT: increase of smoke and aggressive gas purification efficiency by complex carrying out of dust and gas catching in devices with large diametre, and consequently larger productivity, with simultaneous reduction of energy consumption, reduction of atmosphere pollution degree.
