Embodiment Construction

[0014] Such as figure 1 As shown, the upper head (2) and the tower section (9), the tower section (9) and the lower head (10) are connected through the flange (4), and the sealing ring (3) is arranged at the joint; on the upper head ( 2) There is an upper material port (1) on the top, and a lower material port (11) is provided on the lower head (10); the tray (6) is placed in the groove at the upper end of the tower section (9); the tray (6) The periphery is fixed with gasket (5) and plays a sealing role. The liquid material enters from the upper material port (1), and flows down step by step to form a liquid curtain to the lower tray (6), and the gas enters through the inlet pipe (7), and rises step by step around the plate from bottom to top to intersect with the liquid curtain. flow contact reaction. The tower section is provided with a jacket (8) for heat exchange.

[0015] Tray (6) is directly made of materials such as metal, acid-resistant pottery, and also can be mad...

Abstract

The present invention relates to gas liquid conduction equipment-board tower. The board tower consists of several tower burls where lays tower board. The liquid is flowing along the board weir and distributing dentation board by board like a curtain. When the gas and liquid meet and react, it will become adverse current. The tower tray is arc and there are sawtooth upside weir and underside distributing dentation. The tower burl and tower board are made from metal, acid-resistant pottery that are corrode-resistant or package steel corrode-resistant. The present invention can prevent from separating out and jam of the gas and liquid. The equipment can provide conduction value and conduction area. It operates flexibly and resistance value is little.

Description

Technical field: [0001] The invention relates to a gas-liquid phase mass transfer equipment-a plate tower, which can be used for gas-liquid phase reactions or other contact situations of gas-liquid phases, and belongs to gas-liquid mass transfer equipment. Background technique: [0002] Regarding the design of gas-liquid mass transfer equipment, generally proceed from the process law, usually good gas-liquid contact provides the largest mass transfer coefficient and mass transfer area and has the largest possible countercurrent to form the maximum concentration gradient to provide the actual maximum driving force. Conventional tower equipment takes into account the engineering factors of gas-liquid mass transfer equipment, and pursues the largest possible specific surface area by modifying the tray structure in the tower body or installing packing to promote gas-liquid mass transfer. For solution-type mass transfer equipment between liquid and gas, often due to insufficient...
