KOCHETOV'S VERTICAL ADSORBER Russian patent published in 2015 - IPC B01D53/02 

FIELD: machine building.

SUBSTANCE: vertical adsorber containing the cylindrical housing with conic cover and the bottom; the cover has the loading hatch, the union for initial mix supply with the distributive grid, the union for discharge of desorption vapours and the union for the safety valve. The stiffening ring is provided in the place of joint of the cover and the housing, and in the middle part of the housing on the bearing ring the beams with supports are installed which support the grid-iron on which the gravel layer is laid. The adsorbent layer is located between the gravel layer and the grid on which the loads for prevention of adsorbent ablation during desorption are located, and unloading of the spent adsorbent is performed through the unloading hatch installed in the housing, and in the bottom the bubbler and the inspection hatch with the union for condensate discharge and water supply is mounted. The bubbler has toroidal shape and is fixed on conic surface of the bottom by means of spacers, and the coefficient of perforation of toroidal surface of the bubbler is within the optimum interval of the values K = 0.5…0.9, and the union for discharge of treated gas is located on conic surface of the bottom. The adsorption and desorption process proceeds at the following optimum ratios of the elements forming the device: the ratio of the height N of cylindrical part of the housing to its diameter D is within the optimum ratio of the values H/D = 0.73…1.1; the ratio of the height N of cylindrical part of the housing to the thickness S of its wall is within the optimum ratio of the values H/S = 220…275; the ratio of the adsorbent layer height H₁ to the height N of cylindrical part of the housing is within the optimum ratio of the values H1/H = 0.22…0.55; the ratio of the adsorbent layer height H1 to the height H₂ of gravel layer is within the optimum ratio of the values H₁/H₂ = 5.0…12.0. Adsorbent is implemented in the form of, at least, three coaxially arranged hemispherical surfaces mutually joined with a gap by means of the fastener through axisymmetrically arranged spacer elements in the form of rings, and between hemispherical surfaces the corrugated elements with the shape of generatrix surface, equidistant to hemispherical surfaces, are fixed on the spacer elements, or spacer elements in adsorbent are implemented in the form of cylindrical screw springs.

EFFECT: increase of level of purification of gas flow from target components and dust due to increase of the area of contact of adsorbent with a target component.
