SCRUBBER WITH MOVABLE NOZZLE Russian patent published in 2008 - IPC B01D47/06 

FIELD: ventilation; moist dust collection technology.

SUBSTANCE: scrubber with a movable nozzle consists of casing with pipe fittings for dusty and cleaned gas, spraying equipment, lower bearing distributing plate, made of elastic materials with vibrators. In between these plates there is a nozzle sheet mist extractor and slime discharge facility. The nozzle is made in the form of hollow spheres, on whose surface there screw grooves, or in the form of cylindrical rings on whose side surfaces are screw grooves. The spraying equipment is made in the form of spraying facility installed on the perimeter of a collector whose surface form is equidistance from the scrubber casing surface, centrifugal sprayer, which consist of casing with inlet apertures, lid, airtight washer between casing and lid, springs between lid and twister which is made in the form of a turned-up bottom of a cylindrical bowl and has a circular spacing relative to the casing. The twister has at least two rows of throttle apertures and in each row; there are at least, evenly spaced tangential throttle apertures along the circumference of the twister wall. On the lower part of the casing, there is a bush in the form of a conical washer, calibrated with conical apertures and lies on the same axis as the cylindrical and reverse tapered relative to the conical bush obliquity.

EFFECT: enhancing effectiveness and reliability of dust collection process by way of increasing the water dispersion rate using sprayers.
