ADSORPTION METHOD BY KOCHETOV Russian patent published in 2014 - IPC B01D53/02 

FIELD: machine building.

SUBSTANCE: adsorption method implies that a gas flow for cleaning is supplied to the lower part of an apparatus through a distribution grid, then it is passed through the external and internal perforated cylinders between which adsorbent is placed, the cleaned gas flow is withdrawn from the adsorber via a connecting pipe, and the waste adsorbent is removed via a discharge gate, the desorption is carried out by supplying the water vapour to a bubbler via the connecting pipe, the bubbler is fitted by perforated toroidal surface for smoother desorption process along the whole height of the perforated cylinders, the adsorbent is made as a cylindrical ring with two hemispherical surfaces being attached to its side surface opposite to each other so that diametral planes of the hemispheres coincide with the upper and lower bases of the cylindrical ring respectively, and the apices of the hemispherical surfaces are set on the ring axis and are turned to each other, and perforation is provided on the side surface and on the hemispherical surfaces.

EFFECT: improved cleaning of a gas flow from blending agent due to increased contact area between the adsorbent and the blending agent.
