CONIC NOZZLE SCRUBBER Russian patent published in 2009 - IPC B01D47/06 B05B17/06 

FIELD: mechanics, production processes.

SUBSTANCE: conic nozzle scrubber contains the case with branch pipes for dusty and cleared gas, nozzle-irrigating device, basic and constricting plates between which the nozzle is located, liquid trap representing a layer of the nozzle arranged between basic and constricting plates and slime removal device. Basic plates are made elastic, while the nozzle placed above the bottom basic plate is made from elastic materials, for example in the form of polyethylene spheres, the vibrator being arranged on the bottom basic plate. The nozzle represents hollow spheres with their spherical surface furnished with the screw flute cut thereon, or the nozzle represents a helical line formed on a spherical surface. The irrigating device represents an acoustic atomiser for spraying liquids, and comprising the case with the generator of acoustic vibrations fitted therein and representing a combination of a nozzle and a resonator and a pipe for supply of the sawing agent and liquid. The case represents a glass with the bottom. The generator of acoustic vibrations is arranged inside the case and represents a hollow core with a wedge slot and a nozzle. The liquid is supplied to the circular gap formed between the resonator external surface and the nozzle internal surface, while the liquid supply channel is located tangentially to the glass internal surface and represents a rectangular slot. Air is forced through the union fitted in the case and the resonator orifice to get at least in one wedge slot arranged at the angle to the resonator axis. Note here that angle varies from 30° to 60°. A helical guide device is arranged in the circular gap between the glass internal surface and the resonator external surface to facilitate swirling the liquid fed via the channel.

EFFECT: increase in efficiency and reliability of dust separation.
