GAS-LIQUID CONTACT EQUIPMENT

摘要

PURPOSE:To improve the gas-liquid contact efficiency by constituting the title equipment of the plates provided with the reverse directional trays having a plurality of aperture parts in which the aperture faces on the trays passing the raised gas are opened toward the upstream direction of liquid for the flow direction of the liquid on the trays. CONSTITUTION:Slurry introduced on a reverse directional tray 1 is allowed to flow to the direction shown in an arrow A and overflowed over an outlet weir 2 and passed through a downcomer 3 and introduced on the lower-step reverse directional tray 1. On the other hand, steam is blown out toward the direction B reverse to the flow direction of slurry according to the aperture direction of the aperture face and solid substance precipitated on the tray is lifted therewith and distribution width of stagnant time of resin is made narrow and thereby the gas-liquid contact efficiency is improved.
