<p>PURPOSE:To uniformize a liq. flow by forming plural passages with two partition plates and two side plates, and providing plural rectangular trays in each passage while alternately shifting the liq. shoots of the adjacent upper and lower trays from each other. CONSTITUTION:The passage 5 is formed by the partition plates 2 and 2 and the side plates 3 and 3. A liq. is supplied from the upper part of the passage 5, flows down through the liq. shoot 7, overflows an inlet weir 11 through a pan 12, is brought into contact with a gas ascending from the underside on a gas-liq. contact plate 10, and overflows a weir 13 on the shoot side into the shoot 7. As a result, the gas-liq. contact is repeated at the gas-liq. contact plate 10 of the tray 6, and the liq. flows down to the lower tray. The joints between the tray 6 and the partition plate 2 and between the tray and a side bar 4 are hermetically sealed, hence bypasses for gas and liq. are not formed.</p> |
