HEAT-AND-MASS EXCHANGER Russian patent published in 2009 - IPC B01D3/32 B01D53/18 

FIELD: mechanics.

SUBSTANCE: proposed heat-and-mass exchanger is intended for interaction of gas and fluid and can be used for cooling and purification of the contact gas from catalyst dust and steam stripping of hydrocarbons from water condensate in production of styrene by ethyl benzene dehydrogenation. The cylindrical casing top accommodates fluid intake and gas discharge branch pipes while the cylindrical casing bottom has fluid discharge branch pipe and the gas main feed pipeline. Just above the latter, a baffle followed by one or several disks and a device for gas and fluid to interact therein. The said disk feature central bores. Note here that the lower disk bore diameter is smaller than that of the gas feed pipeline, and that the bore diameters of the upper disk are smaller than those of the lower disks. The disks in question have the diameter equal to that the baffle.

EFFECT: higher efficiency of mass-and-heat transfer due to improved gas flow distribution over exchanger diameter.
