CONICAL JET SCRUBBER Russian patent published in 2018 - IPC B01D47/06 B05B1/34 

FIELD: dust collection technique.

SUBSTANCE: invention relates to wet dust collecting equipment. Conical nozzle scrubber contains the housing with nozzles for dusty and purified gas, the spray irrigation device (7), support and limiting plates, between which the nozzle and the liquid trap are located, made in the form of a nozzle layer (9), which is placed between the support (5) and restrictive (6) plates, and the device for removing sludge (4). Support plates are made to be elastic, and the nozzle (9), which is placed above the lower support plate, is made of elastic materials, for example in the form of hollow polyethylene balls, on the spherical surface of which the screw groove is cut. Vibrator is mounted on the lower support plate. Irrigation device (7) is made in the form of a nozzle containing the cylindrical chamber (11) for gas supply, the axial irrigator (13) with throttle openings (16) for supplying liquid and a swirler of gas-liquid flow. Sprinkler with throttle openings is plugged from the output end by the centrifugal element consisting of sequentially connected profiled discs (20) and (21), on the end part of which protrusions and depressions are made in the form of an Archimedes spiral. Protrusions on one disk enter with a gap in the depressions on another disk, with the formation of a channel in the form of an Archimedes spiral, which communicates with the cavity of the cylindrical chamber (11). In the end part of the cylindrical chamber (11), at the inlet of gas and liquid flows, there is the disk (14) with perforations (15) for the entrance of gas, which with its inner surface is rigidly connected to the inlet tube (12) for supplying irrigated liquid. In the cylindrical chamber, two swirlers (17) and (18) are installed in series, while the swirl (17), which is located at the gas flow inlet, is rigidly fixed to the sprinkler (13) tube (12), and the swirler (18) is rigidly fastened at the outlet to the inner surface of the cylindrical chamber (11). Between the swirlers there are two gaps for interaction with gas and liquid: the axial gap (24) for interaction with liquid, and the tangential gap (25) for interaction with gas, at the same time, each of the swirlers is made parabolic in the shape of an elliptical paraboloid, whose guide vanes are curved along a helical surface and form curvilinear confused channels (26).

EFFECT: increased efficiency and reliability of the dust collection process by increasing the liquid spraying rate of injectors.
