ANNULAR ABSORBER Russian patent published in 2018 - IPC B01D53/02 

FIELD: gas industry.

SUBSTANCE: invention relates to equipment for adsorption in a gas (steam) - adsorbent. This is achieved by fact, that in the annular absorber containing a cylindrical housing with a cover and a bottom, made with elliptical shape, wherein loading and inspection hatches are mounted in the cover, wherein the loading hatch is connected to the compensation hopper, located in the cover, and the nozzle for supply of the initial mixture, drying and cooling air is located in the housing lower part, in which the supports are fixed for the base to the outer and inner perforated cylinders, vapors and condensate evacuation during desorption and for water supply union is located in the bottom, in which the purified gas and the exhaust air discharge and for the water vapor supply union is attached, wherein it is fixed through the collector, having two channels, wherein in one of which a damper for the desorption process is located, with a bubbler, along the perforated cylinders entire height the bubbler is made of toroidal form, and the union for the safety valve is installed in the upper part of the housing, and the adsorption and desorption process proceeds at the following optimum ratios of the device constituent elements: the bubbler toroidal surface perforation coefficient lies in the optimum range of values: K=0.5…0.9; ratio of the housing cylindrical part height H to its diameter D is in the optimum ratio of the values: H/D=2.0…2.5; ratio of the housing cylindrical part height H to its wall thickness S is in the optimum ratio of the values: H/S=580…875, wherein the adsorbent is made in the form of balls, as well as solid or hollow cylinders, grains of an arbitrary surface, produced during its manufacturing process, as well as in the form of short sections of thin-walled tubes or rings identical in height and diameter sizes: 8, 12, 25 mm, adsorbent is made in the form of at least three coaxially arranged hemispherical surfaces, connected to each other with a gap via axially symmetric arranged spacer elements in the form of rings by means of a fastener, and on the spacer elements between the hemispherical surfaces corrugated elements are fixed, having form of the surface generatrix, equidistant to hemispherical surfaces, or the spacer elements in the adsorbent are in the form of cylindrical helical springs.

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.
