Abstract

The invention discloses a multi-downcomer tower tray and a plate tower provided with the multi-downcomer tower tray. The tower tray comprises a tray body, at least one jump prevention plate, and at least two downcome assemblies, wherein the jump prevention plates are arranged on the tray body to divide the tray body into at least two areas; the downcome assemblies correspond to the areas respectively; each downcome assembly comprises at least one tower plate, at least one downcomer and at least one liquid receiving tray which are parallel to one another; and the downcomers and the liquid receiving trays are located on the two transverse sides of the tower plate. According to the tower tray, in each downcome assembly corresponding to each area, flow directions of liquid are the same, and flow distances are basically the same, so that liquid-gas ratios on the corresponding tower plates are basically the same, distribution of gas-liquid phases is more uniform, and the processing capacity and the plate efficiency of the multi-downcomer tower tray are improved.

Description

technical field [0001] The invention relates to the technical field of chemical production equipment, in particular to a multi-downcomer tray and a plate tower with the same. Background technique [0002] The general tray tower uses the tray as the basic component of the gas-liquid contact. On the tray, the gas-liquid two-phase flows in a cross-flow manner. The downcomer then enters the liquid receiving tray of the next tray. According to the flow direction of the liquid on the tray, the tray tower can be divided into two types. The flow direction of the liquid on the tray of the first type of tray is basically parallel, and the flow distance is basically the same, which is called overflow tray; The flow of the liquid on the tray of the second type of tray is a diffuse flow or a contraction flow or a combination of the two, collectively referred to as a multi-downcomer tray, such as the ADV-MP tray of AMT Company (US Patent 6,746,003 and Chinese Patent 200380110811.7), She...
