CONICAL JET SCRUBBER WITH VORTEX SPRAYER Russian patent published in 2018 - IPC B01D47/14 B01D53/18 

FIELD: instrument engineering.

SUBSTANCE: invention relates to wet dust collecting equipment. Conical nozzle scrubber with a vortex sprinkler, containing a body with spigots for dusty and clean gas, a spray nozzle, support and restrictive plates between which the nozzle is located, a splatcher made in the form of a nozzle layer located between the supporting and restricting trays, and a device for removing slurry, the support plates being elastic, the nozzle positioned above the lower support plate is made of resilient materials, for example in the form of polyethylene balls, and a vibrator is mounted on the lower support plate, the nozzle is made in the form of hollow balls, on the spherical surface of which a screw groove is cut, or the nozzle is made in the form of a screw line formed on a spherical surface and having a section perpendicular to the helical line, a type of a circle, a polygon, a Berl saddle or an Itallox saddle, characterized in that the irrigation device consists of a cylindrical part with an external thread for connecting a distributing pipeline leading to the liquid, a conical transition part and a cylindrical part with a large diametrical cross-section and with an internal threaded surface, and coaxially with the body in its lower part a nozzle is attached, formed by the cylindrical surface with an external thread interacting with the cylindrical part of the body, the cylindrical surface of the nozzle passes into the conical surface and closes the end perpendicular to the axis of the housing by a blind partition with a jet in its center made with an axisymmetric nozzle consisting of a cylindrical and conical throttle holes, connected in series, the larger diameter of the conical opening being located on the blind partition of the nozzle, the body and nozzle forming three coaxial inner cylindrical chambers, and on the nozzle on the side opposite the liquid supply, an additional row of jets is formed which are formed by at least three pairs of mutually perpendicular vertical channels for passage of liquid and horizontal channels that intersect on the conical side surface of the nozzle and form the outlets of each nozzle, wherein the pair channels are arranged at right angles to each other in the longitudinal planes of the housing, the conical side surface of the nozzle is formed with an apex angle of 90°, and the jet, made in the center of a blind partition and consisting of a cylindrical and conical throttle holes, has helical surfaces on the internal surfaces of both the cylindrical and conical throttle openings, while on the inner surfaces of the nozzle channels of the nozzle, which intersect on its conical lateral surface and which are formed by at least three pairs of mutually perpendicular vertical and horizontal channels for passage of liquid, screw surfaces are made, the direction of the helical surfaces in these channels is made in an opposite direction, the three inner-cylindrical chambers co-axially formed by the body and the nozzle, one of which serves to supply liquid, the other is an expansion chamber, and the third is the function of a pressure chamber of increased pressure, filled with an elastic mesh element, or shavings of non-ferrous metal, or plastic shavings, to the end surface of the cylindrical body part is attached a diffuser, covering the conical surface of the nozzle with a blind partition and a jet, and in the outlet section of the diffuser attached to the end surface of the cylindrical body part, a perforated barrier is installed to which at least two spokes are fixed to one end at the point of its intersection with the axis of the atomizer, the second end of which is fixed to the inner surface of the diffuser in such a way that the spokes are perpendicular to the inner surface of the diffuser, and on the spokes in their central part are freely installed additional sprayers, made in the form of screw drums, which are fixed on the spokes with the help of stops.

EFFECT: increasing dust collection process efficiency and reliability.
