IMPULSE-2 MOVABLE NOZZLE SCRUBBER Russian patent published in 2008 - IPC B01D47/14 B05B17/06 

FIELD: engines and pumps.

SUBSTANCE: proposed taper nozzle scrubber incorporates a housing with a dusty and a purified gas branch pipe, a nozzle spraying system, a lower bearing and constricting plate and upper constricting plate with an adapter arranged there between, a mist eliminator representing an adapter layer fitted between the aforesaid plates and a mud separator. Note here that the bearing plates are elastic and the aforesaid adapter arranged above the lower bearing plate is made in elastic materials and represents hollow polyethylene balls or a helical line cut on a spherical surface of the said balls. Note also that the vibrator is arranged on the said lower bearing plate. The aforesaid spraying system represents an acoustic nozzle incorporating a casing housing a cavity resonator to generate acoustic oscillations and air-and-liquid feed nozzles. The casing is made up of an upper cylindrical and lower parts jointed together by, at least, two rods, the upper part accommodating a union with cylindrical and taper aligned orifices to feed a spraying agent, for example, air. Note that the said union inside accommodates the said nozzle furnished with the central liquid feed orifice and aligned with the union, the said nozzle being rigidly locked by the locking plates interacting with the said liquid feed central orifice inner surface. The rod is arranged inside the aforesaid sleeve and aligned with it, the rod end being furnished with the aforesaid cavity resonator pressed therein and representing a taper-surface cup and the rod tail being furnished with locating plates to interact with the sleeve inner surface. The aforesaid lower flange accommodates, at least, one nozzle arranged at the angle to the cavity resonator axis varying 20°÷40°. Note here that the nozzle axis continuation lies on the circumference located at the resonator taper surface center.

EFFECT: higher efficiency and reliability provided for by increasing spraying efficiency.
