DEVICE AND METHOD FOR WET CLEANING OF GASES Russian patent published in 2009 - IPC B01D45/14 

FIELD: technological processes.

SUBSTANCE: device and method for wet cleaning of gases are intended for gas cleaning from hazardous admixtures and may be used in various industries. Device comprises cylindrical body with disk rotor, on hollow shaft of which, parallel to each other, permeable porous disks are fixed. Fan is installed coaxially to shaft at the outlet in volute-type jacket with drop catcher. There are inlet and outlet nozzles provided in the body for gas, as well as inlet and drain holes for liquid. Hollow shaft and permeable disks are installed in pressurised shell. Annular bores with holes are arranged in walls of hollow shaft and pressurised shell, in areas of contact with permeable disks. End surfaces of disks are partially closed with screening plates, which are installed at inlet surface of disk along with the flow near periphery, and also at the outlet from disk, closer to its central part. Method includes supply of contaminated gas and liquid sorbent flow, their interaction, separation and separate discharge of cleaned gas and liquid wastes of cleaning. At the same time flow of contaminated gas is supplied to permeable porous disks of rotor, and sorbent - to hollow shaft and through holes in annular bore of shaft into disk body.

EFFECT: improved effectiveness and efficiency of gas cleaning from hazardous admixtures, with reduction of plant dimensions.
