COMBINED LIQUID MANIFOLD-MIXER FOR MASS EXCHANGE COLUMN Russian patent published in 2008 - IPC B01D3/20 

FIELD: engines and pumps.

SUBSTANCE: manifold (1) is used to gather and mix liquid coming from the mass exchange column upper zone wherein fluid media flows are treated to produce rectification products. Manifold (1) incorporates two or more liquid gathering areas (10, 11, 12), and two or more headers (5, 6, 7) arranged along the liquid gathering area periphery. A set of ducts and deflecting devices are arranged at a distance within the limits of every liquid gathering area (10, 11, 12), vapor flow passages being formed in the intervals between adjacent ducts. Deflecting devices direct the liquid flowing down into the ducts and cut off the vapor flow passages, thus blocking the liquid down flow. The ducts in every liquid gathering area (10, 11, 12) are grouped so that one group of ducts can direct gathered liquid, primarily, in one header while the other group ducts the said liquid into another header. Preferably, approximately equal quantity of liquid from every gathering area is directed into two headers to ensure a uniform concentration and similar composition. One or several headers (5, 6, 7) include a drain cup (8, 9) for a directed feed of the liquid from the header towards the power area. Since liquid gets mixed up in the manifold, a separate mixer is of no avail. This is why the column vertical space, wherein a mixer is usually arranged, incorporates a nozzle or any other internal appliances increasing the column efficiency.

EFFECT: higher efficiency.
