DESUBLIMATOR Russian patent published in 2006 - IPC B01D7/02 

FIELD: chemical industry; petrochemical industry; other industries; devices for extraction of the crystalline matters from a gaseous phase.

SUBSTANCE: the invention is pertaining to the devices for extraction of the crystalline matters from a gaseous phase and may be used in chemical, petrochemical and other industries. The desublimator includes at least one motionless cylindrical body with the stationary knives and their cooling jacket, an internal rotating drum with the knives passing at rotation through the intervals of the stationary knives, the collector of the crystals. The motionless cylindrical body is established vertically on the hatch, the internal rotating drum is made in the form of a set of the hollow conical lenses, the internal and external diameters of which are tightly connected among themselves. On the outside diameters of the disks there are the mounted knives having the delta shape. On the external motionless cylindrical body there are knives having a rhomb shape, the front part of which is located in the cavities between the conical disks of the lenses. The lower butt of the vertical motionless cylindrical body of the desublimator is established on the hatch of the horizontal collector of the crystals, inside which there is a screw-type stirrer with the screw vane. In the upper part of the collector of the crystals there is a union of the gases outlet, and in the lower part of the collector - a union for the crystals withdrawal. The invention allows to increase the heat-exchange surface of the desublimator at a moderate volume and to raise its production capacity.

EFFECT: the invention allows to increase the heat-exchange surface of the desublimator at a moderate volume and to raise its production capacity.
