CENTRIFUGAL GAS SCRUBBER Russian patent published in 2018 - IPC B01D47/06 B05B1/34 

FIELD: dust collection equipment.

SUBSTANCE: invention relates to a wet dust collection device and can be used in chemical, textile, food, light and other industries for the cleaning of dusty gases. Increasing the efficiency and reliability of the dust collection process is achieved in a centrifugal gas scrubber containing a body, a nozzle for the injection of dusty gas, a branch pipe for the outlet of purified gas, spraying device with injectors and a slurry tank, where the spraying device is made in the form of at least three water collectors, each of which has at least three nozzles for spraying of the body walls, each of which is made in the form of a hollow cylindrical chamber closed on one side, having a tangential longitudinal groove for discharging liquid, the direction of the twist of the atomized liquid in each water manifold opposite the twist in the previous one, each of the nozzles on the water manifolds comprises a body, and a co-axially arranged swirling insert with them, an expanding channel is provided in the connection for supplying liquid to a cylindrical hole which is axially symmetric to the body and smoothly passes into a coaxial with it shaped aperture made in the form of a diffuser, and in the cylindrical bore of the housing, axially symmetric to it, a cylindrical vortex insert is installed having external peripheral helical threaded channels. On the axis of the vortex insertion, there is a central axial hole with a screw thread on the inner surface, opposite to the channel cutting direction, a perforated disk is installed in the upper part of the union, and a screw thread is made on the surface of the hollow screw conical swirler.

EFFECT: increased dust collection process efficiency and reliability.
