KOCHETOV ANNULAR ADSORBER Russian patent published in 2016 - IPC B01D53/00 

FIELD: chemistry.

SUBSTANCE: invention relates to equipment for adsorption in a gas (steam) - adsorbent. This is achieved by the fact that in circular adsorber comprises cylindrical housing with elliptical cover and bottom, the cover has loading and inspection hatches, wherein the loading hatch is connected to hopper made in the cover, and a nozzle for feeding the initial mixture, drying and cooling air is located in lower part of the housing, in which there are supports for base under external and internal perforated cylinders; note here that used adsorbent is discharged via discharge port installed in the lower part of the housing, which is fixed in, at least, three mounts, and the union for discharge of vapours and condensate and water feed is located in the bottom, in which a union for discharge of cleaned gas and waste air and steam supply, besides, it is fixed through the collector, having two channels; note here that in one of which is located for desorption, with bubbler, bubbler has toroidal shape along the whole height of perforated cylinders, union for safety valve is installed in the upper part of the housing, and the adsorption and desorption processes feature the following optimum ratios of components of apparatus: perforation factor of bubbler toroidal surface is within optimal range of values: K = 0.5…0.9; ratio of height H of cylindrical part of housing to its diameter D is within optimal range of values: H/D = 2.0…2.5; the ratio of height H of the cylindrical part of housing to the wall thickness S is within optimal range of values: H/S = 580…875, the adsorbent is made in the form of balls, as well as solid or hollow cylinders, grains of arbitrary surface obtained during its manufacture, as well as in the form of short pieces of thin-wall tubes or rings of equal size along height and diameter: 8, 12, 25 mm.

EFFECT: technical result consists in increase of degree of gas flow purification from target component due to increased area of contact of adsorbent with target component.
