ABSORBER Russian patent published in 2018 - IPC B01D47/06 

FIELD: chemistry.

SUBSTANCE: invention relates to technique for purifying gases from poisonous components. Absorber comprises housing with nozzles for dusty and clean gas, irrigation device, support grids between which nozzle if arranged, and device for sludge removal, nozzle is formed in form of a cylindrical ring to the side surface of which two hemispherical surfaces are oppositely attached to each other in such a way that the diametral planes of the hemispheres coincide respectively with the upper and lower bases of the cylindrical ring, nozzle element is perforated both on the side surface and on the hemispherical surfaces, and between vertices of the hemispherical surfaces of the nozzle element is a perforated surface of the n-th order, for example, spherical, elliptical, hyperbolic, or in form of hemispherical surfaces, inside of which concentrically and with a gap are located at least two hemispherical surfaces, or nozzle is made of a hollow spherical shape, on the outer surface of which there are additional elements in form of spherical, conical surfaces, or any surface of the bodies of rotation, for example, a paraboloid, ellipsoid, and inner spherical surface of nozzle is connected to outer one by means of at least three channels, or nozzle is made in form of a cylindrical ring, on the side, inner and outer surfaces of which a screw thread is made in opposite directions, or nozzle is made in form of a ball on the surface of which non-blind holes of hemispherical shape are made.

EFFECT: technical result is an increase in the efficiency and reliability of the dust collection process.
