A mass transfer tray

Abstract

The invention relates to a mass transfer column tray which comprises arched column tray plates and structured packing, wherein the top of each arched column tray plate is closed, and the lower part of each arched tray plate is opened; gas-liquid channels are formed in the arched column tray plates; sealing plates are arranged at the end socket, the end tail and the middle part of each gas-liquid channel; the multiple arched column tray plates are connected with one another side by side to form an integral column tray; the structured packing is arranged between every two adjacent arched column tray plates. The mass transfer column tray has the advantages that a gas-liquid mixing phase can be well mixed in the gas-liquid channel of the arch-shaped column tray plates, so that the mass transfer effect is greatly enhanced; after the gas-liquid mixing phase flows out of the arched column tray plate, the problem of entrainment is solved by packing layers; meanwhile, the mass transfer column tray is convenient to detach, can be used for achieving self-supporting structurally and is high in intensity, and materials are saved.

Description

technical field [0001] The invention relates to a tray, in particular to an efficient mass transfer tray. Background technique [0002] Due to its good mass transfer performance, the vertical sieve tray column is widely used in industry. Its structure is that there are large holes on the tower plate, and various types of caps are arranged on the holes correspondingly. There are gas-liquid holes above the caps, and gaps are left at the parts where the caps are fastened to the tray. Its working principle is: when the liquid flows into the cap through the gap, the gas from the bottom of the tray rises from the opening to the inside of the cap, and the liquid in the cap is pulled and atomized along the inner wall of the cap, and the gas and liquid are separated. The phase undergoes mass transfer in the cap and forms a gas-liquid mixed phase. The gas-liquid mixed phase is ejected from the gas outlet on the upper part of the cap. The gas phase continues to rise, and the liquid dr...

Problems solved by technology

[0003] Although the vertical sieve plate pulls the film and atomizes the liquid phase in the cap through the gas phase, forming a good gas-liquid contact and improving the mass transfer efficiency, but its structure is not ideal. For example, the vertical sieve plate needs to be placed in the tower Holes are opened on the tray, and then caps are installed above the openings. This structure not only wastes materials, but also reduces the mechanical strength of the tray when the opening ratio is large, and the thickness of the tray plate increases. At the same time, it is very difficult to disassemble and assemble. trouble

In addition, when the gas-liquid mixture passes through the opening above the cap, it often causes serious mist entrainment
