VAPOUR-LIQUID CONTACT DISK AND METHOD OF ITS APPLICATION Russian patent published in 2008 - IPC B01D3/20 B01D3/22 

FIELD: heating.

SUBSTANCE: invention concerns mass- and heat-exchange columns. Particularly it concerns vapour-liquid contact disks used for mass- and heat-exchange columns. Mass-exchange column (1) includes framework (2). In open internal space (3) of it are installed vapour-liquid contact disks of two types interleaved vertical and separated from each other: centrifugal disks (4) and centripetal disks (5). Every of disks (4, 5) has an active platform (6), supplied by assemblage of vapour-throughput channel, which make possible vapour passing upwards, through active platforms (6) for interaction with fluid flows, passing on its upper surface. Active platform (6) of every centripetal disk (4) supplied at least by one central overflow pipe (12), mounted downwards of hole made in platform (6), intended for fluid removal from upper surface of active platform (6) and outfitted by bottom discharge opening which is located upward superior surface of underlying disk's (4) platform (6). Inside the central overflow pipe (12) can be located effuses from central overflow pipe (12) swirling flow structure. Active platform (6) of every centripetal disk (5) also supplied at least by one annular in the plan peripheral overflow pipe (10) which is made downwards of periphery active platform (6) and intended for fluid removal from upper surface of active platform (6) and outfitted by lower discharge aperture which is located upward superior surface of active platform (6) of underlying centripetal disks (5). Mass-exchange column (1) can additionally contents reference rings (24) for every couple of disks (4, 5) or one or even more deflecting elements (26) or either.

EFFECT: invention supplies more effective contact steam upflow and fluid downstream.
