DEVICE FOR PURIFICATION AND UTILISATION OF WASTE GASES OF BOILER ROOMS Russian patent published in 2012 - IPC B01D47/00 F23J15/00 

FIELD: chemistry.

SUBSTANCE: hot, unpurified combustion gases from boilers are supplied through input gas duct into filled with water precipitation chamber, round the partition and through water layer are directed into output gas duct. Auxiliary reservoir with circulation pump is installed for supporting constant water level. In lower part of precipitation chamber located is tubular coil, by which return water, supplied from heat supply network. Successively with precipitation chamber in direction of gas movement into gas tract included is smoke exhauster, made in form of tube chamber, inside which shaft with blades, brought into rotation by low-speed electric drive, rotates. Rotating blades are lowered below water level and create dispersed moisture for additional purification of exhaust gases.

EFFECT: invention makes it possible to emit into atmosphere only purified and cooled smoke gases of boiler room.
