Abstract

The invention relates to chemical industry equipment for carrying out mass exchange processes in distillation columns, absorbers and other equipment and allows increasing the efficiency of the device by expanding the range of stable operation. Mass transfer) on the plate contains inclined perforated} 1st grooves 4, along which part of the liquid phase moves to drain 3, mine the expanding part of the plate. The presence of perforation in the bottoms of the grooves 4 leads to a partial failure of the liquid phase. A variable perforation density, varying the height of the side walls 6 and the length of the grooves 4, redistributes the liquid phase streams over the plate. 2 Il. S ate 2CO 4 00 figure 1

Description

The invention relates to the instrumentation of mass transfer processes in a gas (vapor) - liquid system and may find application in the conduct of distillation processes, absorption of distillation, and some others.

The purpose of the invention is to intensify the process of mass transfer by expanding the range of stable operation of the plate.

Figure 1 shows a single contact plate, a longitudinal section; figure 2 is the same, the view in the plan.

 one

The plate includes a base 1, consisting of inclined plates, receiving 2 and drain 3 pockets, grooves 4 with perforated bottoms 5. The height of the side walls 6 grooves decreases from the receiving pocket 2 to the drain 3. The bottom of the grooves has a perforation density increasing in the direction of to the drain pocket 3. The length of the gutters is increased from the center to the periphery.

The plate works in a perfect way.

The liquid phase from the receiving pocket 2 enters the base 1 of the tray and interacts with the upward flow of gas (steam). At the same time, a part of the fluid at the entrance to the site enters the inclined chutes 4 and moves towards the drain, the expanding part of the tray. The presence of perforation in the bottoms of the grooves leads to a partial failure of the liquid phase, which provides an additional contact zone. The variable perforation density and the height of the side walls 6 of the grooves 4 substantially activate the fluid inflow in the area directly adjacent to the drain, which prevents

intensive liquid entrainment and allows to expand the range of loads for gas (steam) in the column. The contacted fluid is discharged into the drain pocket 3, and the flow is

the phase rushes to the overlying

plate for further interaction with the liquid phase.
