HEAT-MAS-EXCHANGE APPARATUS Russian patent published in 2006 - IPC B01D3/20 B01D3/32 

FIELD: chemical industry; gas and oil industries; other industries; production of the heat-mass-exchange devices.

SUBSTANCE: the invention is pertaining to the apparatuses used for heat-mass-exchange processes in the systems of gas or vapor-liquid, in particular, to the rectifying, absorption columns, the heterophase reactors of the column type and may be used in various industries. The heat-mass-exchange apparatus contains the body with the connecting pipes of inlet and outlet phases and the disposed in altitude contact plates, each of which is made in the form of the base with the holes, the overflow connecting pipes and the valves, and the collector with the connecting pipes for feeding and withdrawal of the heat transfer medium. The overflow connecting pipe is arranged at the wall of the body and consists of two parts, in the upper part of which on the grating there is the nozzle, and in the lower part there is the heat exchanger made in the form of the jacket with the connecting pipes connected to the connecting pipes of the collector. Above the overflow connecting pipe there is the non-centrally mounted valve with the positive floatability. The technical result of the invention is the increased stability of the heat-mass exchange process in the gas-(vapor)-liquid streams in the broad range of variations of the consumption of the gas (vapor) and the liquid on each plate that improves the quality separations, and simplifies the design.

EFFECT: the invention ensures the increased stability of the heat-mass exchange process in the gas-(vapor)-liquid streams on each plate, improves the quality separations, and simplification the design of the heat-mass-exchange apparatus.
