FLAKE-AND-VALVE PLATE WITH FASTENING Russian patent published in 2020 - IPC B01D3/22 

FIELD: technological processes.

SUBSTANCE: invention relates to devices for steam (gas) and liquid contact in rectification or absorption processes and can be used in chemical, oil refining and other industries implementing these processes of separation of mixtures. Invention provides for elimination of bolt fixtures, spare parts, reduced time of installation, increased flow section for steam (gas) due to fixed valves in area of web attachment. Flake-and-valve plate with fixture includes a base with holes and flat valves installed in them, between which there are cuts in the form of flakes for steam (gas). Valves of trapezoid shape, tapering from receiving pocket towards drain wall, are arranged in staggered order. On the level of narrow parts of the valves, flakes are located, the open part of which is directed towards the liquid movement. Steam jets coming out of flakes and valves are directed perpendicular to edges of flakes, to sides of valves and movement of liquid flow. In production, tray is broken into webs, one web is made with connecting bend and stiffener, on which stationary valves are extruded, the flow section of which can be rectangular, trapezoidal or in the form of a circular segment, between which rectangular connecting slots are located, and on the other tabs are made, which are inserted into connection slots and cuts for fixed valves.

EFFECT: proposed design eliminates bolt fixtures, spare parts, reduces installation time, increases flow section for steam (gas) due to fixed valves in attachment area of webs.
