DUST CHAMBER WITH CENTRIFUGAL NOZZLE Russian patent published in 2008 - IPC B01D47/06 F23D11/04 

FIELD: technological processes.

SUBSTANCE: invention is related to technology of wet dust collection and may be used in different industries for cleaning of dust-laden gases. Dust chamber contains casing, which is installed at elastic elements, inlet of dust-laden gas flow, fan, suction nozzle of which is connected with casing by means of elastic coupling, outlet nozzle of cleaned gas, water sprayers, which alternate with packet of partitions, mist extractor and device for sludge removal. Packet of partitions is made in the form of at least two partitions, one of which serves as baffle element with through opening and is installed in the packet of the latter. The other partition is made as perforated with perforation ratio of 0.5, at that gap between partitions in packet of partitions amounts to 0.01...0.1 from their height. Mist extractor consists of at least three rows of plates installed in the casing, which have wedge-shaped streamlined form in their section that is perpendicular to the length. Water sprayers are made in the form of centrifugal nozzles, every of which consists of casing with inlet opening, cover, sealing gasket between casing and cover, spring, which is installed between cover and swirler. Swirler is made in the form of cylindrical sleeve turned upside down and installed in respect to casing with annular gap. In swirler there are at least two rows of throttling openings, and in every row there are at least two evenly placed along annular wall of swirler tangential throttling openings. In bottom part of casing orifice insert is installed, which is made in the form of conical orifice with calibrated conical opening that is coaxial to cylindrical surface of swirler and has taper that is reverse to taper of inset conical orifice.

EFFECT: increase of efficiency and reliability of dust collecting process.
