KOCHETOV ANNULAR ADSORBER Russian patent published in 2017 - IPC B01D53/00 

FIELD: technological processes.

SUBSTANCE: invention relates to equipment for adsorptive processes in the gas (vapour)-adsorbent system. The annular adsorber comprises of a cylindrical body with a cover and a bottom made in an elliptical shape. The charging and inspection doors being are mounted in the cover, whereby the charging door is connected to a compensating bin, located in the cover, and the nipple for the base mixture supply, drying and cooling of air is located In the lower part of the body, in which the supports for the base are fixed for external and internal perforated cylinders. Discharging of the waste adsorbent is carried out through a discharging door, installed in the lower part of the body, which is fixed in at least three setting claws, and the nipple for vapour and condensate disposal in desorption and for water supply is located in the bottom in which the nipple for stripped gas and waste air extraction and for supplying moisture vapour is mounted. It is fixed through a header, having two channels, one of which contains a flap for the desorption process, with a bubbler. The bubbler is of toroidal form along the entire height of the perforated cylinders, and the nipple for the safety valve is installed in the upper part of the body, and the adsorption and desorption process proceeds at the following optimum ratios of the device components: the perforation coefficient of the toroidal surface of the bubbler lies in the optimum range of values: K=0.5…0.9; the ratio of the height H of the cylindrical part of the body to its diameter D is in the optimum ratio of the values: H/D=2.0…2.5; the ratio of the height H of the cylindrical body part to the thickness S of its wall 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 general surface, obtained during its production, and also in the form of short lengths of thin-wall tubes and rings of equal size of height and diameter: 8, 12, 25 mm.

EFFECT: allows increasing the degree of gas flow purification from the target component due to increasing the contact area of the adsorbent with the target component.
