DUST CHAMBER Russian patent published in 2017 - IPC B01D47/06 B05B1/26 

FIELD: machine engineering.

SUBSTANCE: dust chamber contains a body, an inlet of a dusty gas stream, a fan, a cleaned gas outlet branch pipe, water sprayers alternating with a partition assembly, a spray trap and a sludge removal device. The partition assembly is made in the form of at least two partitions, one of which is a demister pad with a through hole, and the other is perforated. The demister pad with a through hole from the partition assembly is installed last in the assembly. The spray trap consists of at least three rows of plates in the body with a slope from the upper plane to the lower one, and, also, having a wedge streamlined shape in a section perpendicular to the length. The body is mounted on elastic elements, and the suction pipe of the fan is connected to the body by means of an elastic coupling. The water spray is made in the form of an atomizer. The atomizer contains a hollow body with a nozzle and a central core. The body is provided with a channel for supplying liquid and comprises of a coaxial rigidly connected bushing with a nozzle fixed in its lower part in the form of a cylindrical two-stage bushing, the upper cylindrical stage of which is connected by means of a threaded connection to a coaxial central core having a central hole and provided with an annular clearance to the inner surface of the cylindrical bushing. The annular clearance is connected to at least three radial channels formed in a two-stage bushing connecting it to an annular cavity formed by the inner surface of the bushing and the outer surface of the upper cylindrical stage. The annular cavity is connected to the channel of the body for supplying liquid. A spraying device in the form of a truncated cone is rigidly attached to the lower part of the central core and coaxial to the central hole of the core and attached by its upper base to the base of the central core cylinder. A splitter is attached to the lower base of the truncated cone by means of at least three spokes and is made in the form of an end circular plate the edges of which are bent toward the annular clearance. There are spiral grooves on the outer lateral surface of the truncated cone. A throttle opening is provided in the splitter axisymmetrically to the central hole of the central core. An external diffuser is coaxially attached to the lower part of the bushing, which is rigidly connected to the body. An inner perforated diffuser is coaxially attached to the lower base of the truncated cone of the spraying device in such a way that the outlet cross-sections of the external and internal diffusers lie in one plane.

EFFECT: higher efficiency and reliability of the dust recovery process.
