KOCHETOV ADSORPTION METHOD Russian patent published in 2017 - IPC B01D53/02 

FIELD: technological processes.

SUBSTANCE: invention relates to equipment for adsorptive processes in the gas (vapour)-adsorbent system. In the adsorption method, which involves feeding the gas flow to the lower part of the device through a distribution grid for stripping, then driving it through the outer and inner perforated cylinders, between which the adsorbent is placed, the stripped gas flow is discharged from the absorber through a fitting adapter, and the adsorbent is charged though a charging door in the cover. The waste adsorbent is removed through a discharging door. Desorption is done by means of feeding moisture vapour to the bubbler through a fitting adapter. The bubbler has perforated toroidal surface for more steady desorption rate along the whole height of the perforated cylinders. The adsorption and desorption process is carried out at the following optimum ratios of the device components: the coefficient of bubbler toroidal surface perforation lies in the optimum range of values: K=0.5…0.9; relation of height H of the cylindrical portion of the body to its diameter D is within the optimum ratio of values: H/D=2.0…2.5; relation of height H of the cylindrical part of the body to thickness S of its wall is within the optimum ratio of values: H/S=580…875, the adsorbent is toroidal-shaped with a circle in its section, wherein blind grooves are made with respect to the diameter axis of the cross section on both sides. The grooves are formed by the toroidal surfaces, congruent to the main toroidal surface, which has a circle in its section. And the sectional areas of the grooves have a shape elongated in the direction parallel to the torus axis, wherein a groove on one side is located between two neighbouring grooves made on the other side of the torus section.

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.
