摘要:
A gas-liquid contact tray with fixed valves for mass transfer, in which the fixed valve comprising an upstream portion, a midportion and a downstream portion is made by punch from the tray deck so as to form as a deflector, and the upstream portion and the downstream portion are integrated with the tray deck, characterized in that said midportion has a central plane portion and downward inclined margins, and the tray deck is further provided with perforations which are arranged between the fixed valves adjacent in the liquid flow direction. The gas-liquid contact tray with fixed valves for mass transfer according to the present invention has a low liquid entrainment, low liquid weeping, a high mass transfer capacity and good turn-down characteristics.
