PACKED SCRUBBER Russian patent published in 2017 - IPC B01D47/14 B01D53/18 B05B1/26 

FIELD: machine engineering.

SUBSTANCE: packed scrubber contains a body with branch pipes for dusty and cleaned gas, support grids, a fitting and a device for sludge removal. An irrigation device is made in the nozzle form containing a hollow body with a nozzle and a central core. The body has a fluid feed channel and includes a coaxial bushing rigidly coupled therewith and provided with a nozzle secured to its lower part and configured as a two-stage cylindrical bushing. The upper cylindrical stage of the bushing is connected by means of a threaded connection to a coaxially aligned central core having a central opening and installed with an annular gap with respect to the inner surface of the cylindrical bushing, the annular gap being connected to at least three radial openings formed in the two-stage bushing connecting it to an annular cavity formed by the bushing inner surface and an outer surface of the upper cylindrical stage, in this case the annular cavity is connected to the body channel to supply liquid, a sprayer is rigidly fixed to the central core in its lower portion and formed as a truncated cone coaxial to the central opening of the core and attached with its upper base to the central core cylinder base , and 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 an end circular plate. The edges of the plate are bent towards the annular gap, and screw grooves are provided on the outer lateral surface of the truncated cone. A throttle opening is made in the divider axisymmetric to the central hole of the central core, while an external diffuser is coaxially attached to the bushing rigidly connected to the body in its lower part, and an inner perforated diffuser coaxily attached the lower base of the sprayer truncated cone.

EFFECT: higher efficiency of the dust collection process.
