Vertical tower tray and gas-liquid contact mass transfer equipment with same

Abstract

The invention provides a vertical tower tray and gas-liquid contact mass transfer equipment with the vertical tower tray. The vertical tower tray comprises: a tower plate (5), wherein the tower plate (5) is provided with a plurality of open holes (51); and a plurality of mass transfer units (4) arranged on the tower plate (5) corresponding to the plurality of open holes (51), wherein at least one mass transfer unit (4) comprises a fixed cover (42) covering the corresponding open hole (51) and a movable part (43) arranged on the fixed cover (42), a gas-liquid outlet communicated with the corresponding open hole (51) is defined between the movable part (43) and the fixed cover (42), and the movable part (43) is movably arranged relative to the fixed cover (42) so as to adjust the size of the gas-liquid outlet.

Description

technical field [0001] The invention relates to petrochemical production equipment, in particular to a vertical tray and gas-liquid contact mass transfer equipment with the vertical tray. Background technique [0002] Columns are very important equipment in the process of oil refining and chemical production. The form of the tower can be divided into plate tower and packed tower. Tray towers can be divided into sieve plate towers, floating valve towers, solid valve towers, etc. according to their internal tray forms. In the gas-liquid mass transfer process of the plate tower, the liquid phase is the continuous phase, and the gas phase is the dispersed phase. The mass transfer mode of gas in liquid is bubbling, and the degree of dispersion of gas in liquid directly determines the efficiency of gas-liquid mass transfer. [0003] At present, many plate towers use vertical jet trays. The vertical spray tray is a tray with a spray cover with a certain gap between the plate an...

AI Technical Summary

Problems solved by technology

However, these vertical spray trays also have the following problems: the mass transfer effect of the vertical spray trays depends on the gas-liquid ratio, and the above-mentioned vertical spray trays are suitable for gas-liquid mass transfer processes with large quantities, such as dry gas During the amine liquid desulfurization process, water washing cooling process, etc., when the gas phase flow rate is insufficient (less than 60% of the normal load) or the gas volume fluctuates, the vertical spray tray will not be able to achieve normal operation
