PERIODICALLY OPERATING DESUBLIMATOR FOR SEPARATION OF PRODUCTS FROM GAS MIXTURES Russian patent published in 2018 - IPC B01D7/02 B01D5/00 F28D7/10 F28F13/12 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to periodically operating desublimator for separating products from gas mixtures. Desublimator comprises a cylindrical body for extending a gas mixture in its longitudinal direction, a casing wall 10 and inner plates 7, 7', which for desublimating the product are intended to be cooled by means of a cooling means guided through the channels 12 on the housing wall 10, with at least one internal cooling conduit in the cylindrical body, which penetrates the body in the longitudinal direction along its entire length and which has several separate outwardly directed plates 8 which are distributed in a circumferential direction of the cooling pipeline at a distance from each other along the perimeter of the cooling conduit, and which are fixed to the cooling pipe with an orientation in the longitudinal direction of the housing, number of inwardly and/or outwardly directed plates 7, 7', 8 is increased from the inlet end of the body to its outlet end, and the height H1, H2 of the plates 7, 8 varies between adjacent longitudinal sections L1-L6 in order to prevent the formation of gas corridors between the free ends of the plates 7, 8.

EFFECT: desublimator can work at high excess or low pressures in combination with high or low temperatures at the same time, small design costs, with the possibility of uniform heat removal and uniform deposition of the product, which improves the efficiency of the method for obtaining products from gas mixtures.
