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

FIELD: dust collection equipment.

SUBSTANCE: present invention relates to wet dust collection and can be used in chemical, textile, food, light and other industries for purification of gases. In a centrifugal gas scrubber containing a housing, a nozzle for the injection of dusty gas, a branch pipe for the outlet of purified gas, a spraying device and a slurry tank, spraying device is made in the form of at least three water collectors, on each of which at least three vortex nozzles are fixed to irrigate the walls of the shell and its central part, each of the nozzles comprising a hollow cylindrical body with an external thread for connecting to the connection of a distribution pipeline for supplying liquid and a cap nut fixed to the bottom of the body with a liquid flow divider, wherein in the body a cylindrical opening is made coaxially to it, in the upper part of which a strainer is installed, and in the lower part there is a throttle washer with a nozzle and a divider, the liquid flow divider is attached to the end surface of the union nut and is made of a rod type in the form of a truncated tetrahedron fixed to the end face of the union nut, the edges of which are rods with fixed blades with stops in such a way that they can be rotated from the streams emanating from the throttle washer with the jet of the injector, wherein the edges of the tetrahedron base are also connected by rods with fixed blades and stops, and a diffuser is attached to the surface of the intersection of the end surface of the union nut with its outer surface, enclosing by its lateral conical surface the divider of the liquid flow, with the outlet of the diffuser located below the base of the truncated tetrahedron, and the outlet itself is connected to an additional divider in the form of a circular perforated plate perpendicular to the axis of the diffuser, with a screened dome element attached to the perforated plate with a vertex directed away from the nozzle of the nozzle, and the cavity of this element is filled with a porous material, for example a wire of the "knuckle" type, and is axisymmetric to the outlet of the diffuser, to the circular perforated plate of the additional dissector, in its central part, a central cylindrical atomizer is formed, which is made in the form of a cylindrical shell, the solid part of which is located in the mesh dome element, the cavity of which is filled with a porous material, and the perforated part of the cylindrical atomizer extends beyond the mesh dome element.

EFFECT: increased dust collection process efficiency and reliability.
