Abstract
PURPOSE:To improve tray efficiency and to increase treatment capacity by dis posing mesh-like structural members in the froth layers of the gas-liquid mixed phases on each tray in order to fine the foam in the froth layers while maintaining the superficial velocity in a gas-liquid contact column relatively high. CONSTITUTION:A gas-liquid contact column body 1 is divided to a plurality of contact reaction chambers by means of gas-liquid contact trays 2, and these are connected vertically by means of downcomers 3. Vapor ascends by passing through the opening parts 4 of the trays 2, and enters the liquid phase retained between inlet and outlet weirs 5, 6, where it undergoes gas-liquid contact. On the other hand, liquid passes through the clearance at the bottom of the downcomer 3, overflows from the weir 5, flows onto the tray 2, and overflows from the weir 6 while contacting the steam. In this case, the gas-liquid contact state is in the form of froth of gas-liquid mixed phases, and forms a froth layer A between the weirs 5, 6. The small foams (b) produced in the opening parts 4 grow to large foams B as they ascend, and the leyer A arrives at the top surface. However, there are the mesh-like structural members 7 approximately parallel with the trays 2 in the layer A and therefore the foams B are again divided into small foams (c), whereby the gas-liquid contact areas are increased.
