Description

technical field

[0001] The invention relates to a central downcomer cone liquid-distributing high-efficiency mass transfer tray, which belongs to the structural technology of tower internals used for mass transfer and heat transfer in chemical distillation, absorption, desorption and other operations. Background technique

[0002] Vapor-liquid mass transfer equipment is mainly divided into two categories: plate tower and packed tower. Due to the simple structure of the plate tower, low cost, easy expansion and relatively mature experience in design and operation, the large-scale equipment in the current industry is still dominated by the plate tower. The general form of the traditional tray is to set the liquid receiving tray and the downcomer at both ends of the tray as the liquid phase inlet and outlet channels; Holes) come into contact with the liquid phase for mass transfer.

[0003] The structure of the traditional tray makes: first, the downcomer occupies a large are...
