AIR CLEANING DEVICE IN VIBRATION-BOILING LAYER OF LIQUID Russian patent published in 2017 - IPC B01D47/06 B01D47/02 

FIELD: machine engineering.

SUBSTANCE: device comprises a housing, a branch pipe for introducing a dust-laden gas, a branch pipe for discharging the purified gas, and a branch pipe for discharging the cleaned gas, a liquid reservoir, a flushing nozzle, a sludge discharge pipe. The inlet branch pipe for dust-laden gas is made cylindrical. A vibrator is placed in the upper layers of liquid and secured to the housing by means of elastic membrane. A spraying device in the form of a core with injectors is secured on inner surface of the housing. Each injector has a hollow body with a nozzle and a central core. The housing is provided with a channel for liquid supply and contains coaxial bushing rigidly attached thereto with the nozzle fixed in its lower part, and made as a cylindrical two-stage bushing, which upper cylindrical stage is connected by means of a threaded joint with a central core coaxial thereto and having a central hole and installed with annular gap relative to inner surface of cylindrical bushing. The annular gap is connected to at least three radial channels made in the two-stage bushing and connecting thereof with annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical stage. The annular cavity is connected to body channel for liquid supply. The sprayer is rigidly fixed to the central core in its lower part, and made in the form of a truncated cone coaxial to the central hole of the core and attached by its upper base to the base of the central core cylinder. A splitter is attached to the lower base of the truncated cone by means of at least three spokes, and made in the form of end round plate which edges are bent towards the annular gap. There are helical grooves provided on the outer side surface of the truncated cone. A throttle hole is made in splitter axisymmetrically to the central hole of the central core. An outer diffuser is coaxially secured to the bushing rigidly coupled with the housing, and attached in its lower part. An inner perforated diffuser is coaxially secured to lower base of the sprayer truncated cone so that outlet sections of outer and inner diffusers lie in same plane.

EFFECT: increased efficiency and reliability of dust collection.
