Abstract

The utility model discloses a gas raising liquid collecting disc of tower equipment, which comprises a liquid collecting plate, a gas raising cylinder, a supporting rib and a top cover, wherein the circumferential edge of the top cover is fixed with a liquid baffling cylinder, and the liquid baffling cylinder surrounds the gas raising cylinder. The gas raising liquid collecting disc of the tower equipment is provided with the liquid baffling cylinder at the edge of the top cover, the liquid baffling plate can effectively prevent the liquid from leaking in the gas raising cylinder from the gap between the top cover and the gas raising cylinder, so that mass transferring efficiency of tower equipment influenced by leakage can be avoided, and the gas raising liquid collecting disc creates beneficial conditions for the efficient, stable and long periodical operation of the corresponding process devices.

Description

A kind of tower rise the gas catch tray

Technical field

The utility model relate to a kind of tower rise gas catch tray, especially absorption tower and desorber rise the gas catch tray.

Background technology

Remove, take off in wet method in the absorption tower, desorber of process apparatus such as charcoal, gas upwards flows from tower bottom, liquid flows downward from top of tower, by gas, liquid counter current contacting, solute is passed to liquid phase from gas phase in absorption process, solute then is delivered to gas phase from liquid phase in desorption process, realizes mass transport process.In the prior art, absorption tower, desorber rise the gas catch tray as shown in Figure 1, by liquid collecting plate, rise inflator, brace rod and overhead guard and form, gas is upwards mobile through rising inflator, liquid flows downward on the liquid collecting plate from top of tower.In the tower running, since through the upper surface of overhead guard to rising the gas catch tray and rising the mobile partially liq in gap between the gas catch tray, under the effect of interfacial tension, produce capillary flow, promptly the lower surface ecto-entad from the edge of overhead guard along overhead guard flows behind the certain distance again toward falling, and the liquid that falls is from top to bottom carried out disturbance rising the gas that gap between inflator and the overhead guard flows from inside to outside, reasons such as impact, partially liq is from overhead guard and rise gap between the inflator and bleed and rise inflator, promptly rise the leakage in running of gas catch tray, this can reduce the mass-transfer efficiency of tower, to stablizing of respective process device, long-term operation has a negative impact.

Summary of the invention

What technical problem to be solved in the utility model provided a kind of tower that can prevent leakage rises the gas catch tray.

For this reason, the tower that the utility model provides rise the gas catch tray, comprise liquid collecting plate, rise inflator, brace rod and overhead guard that the overhead guard edge is fixed with the retaining fluid cylinder, the retaining fluid cylinder surrounds and rises inflator.

Because the gas catch tray that rises of the tower that the utility model provides is provided with the retaining fluid cylinder at the overhead guard edge, liquid barrier can prevent effectively that liquid is from overhead guard and rise gap between the inflator and bleed and rise inflator, thereby can avoid influencing the mass-transfer efficiency of tower, for efficient, the stable and long-term operation of respective process device creates favorable conditions because of leakage.

Description of drawings

Fig. 1 is the structure cross-sectional schematic that rises the gas catch tray of tower of the prior art.

The structure cross-sectional schematic that rises the gas catch tray of the tower that Fig. 2 provides for the utility model.

The specific embodiment

As shown in Figure 2, the tower that the utility model provides rise the gas catch tray, comprise liquid collecting plate 1, rise inflator 2, brace rod 3 and overhead guard 4, overhead guard 4 edges are fixed with retaining fluid cylinder 5, retaining fluid cylinder 5 surrounds and rises inflator 2, and the lower surface of retaining fluid cylinder 5 and the distance between the liquid collecting plate 1 are less than the height that rises inflator.The shape of cross section that rises inflator 2 in the present embodiment is circle or triangle or polygon, and the shape of cross section of retaining fluid cylinder 5 is identical with the shape of cross section that rises inflator 2.
