Embodiment 1

[0028] Such as figure 2 As shown, suction-type gas-liquid distributors 3 are arranged on the gas-liquid distribution tray tray 2 , and each gas-liquid distributor 3 is surrounded by a diamond-shaped liquid phase cofferdam 4 . The height of the liquid phase cofferdam is 1.0 times the height from the bottom edge of the bubble cap to the gas-liquid distribution plate 2 . When the tray 2 of the gas-liquid distribution tray is horizontally deflected, a small area of ​​relatively independent liquid surface will be maintained between the liquid phase cofferdams 4 to ensure that the gas-liquid distributor 3 in the liquid phase cofferdams 4 can continue to function.

Embodiment 2

[0030] Such as image 3 As shown, suction type gas-liquid distributors 3 are arranged on the gas-liquid distribution tray 2 , and a plurality of gas-liquid distributors 3 are surrounded by a liquid phase cofferdam 4 . The liquid phase cofferdam in the middle is hexagonal, and the other liquid phase cofferdams are fan-shaped. The height of the liquid phase cofferdam is 1.2 times the height from the bottom edge of the bubble cap to the gas-liquid distribution plate 2 . When the gas-liquid distribution plate tray 2 is horizontally deflected, a small area of ​​relatively independent liquid surface will be maintained between the liquid phase cofferdams 4 to ensure that the multiple gas-liquid distributors 3 in the liquid phase cofferdams 4 have the corresponding Adapt to the liquid level, better play a role.

Embodiment 3

[0032] Such as Figure 4 As shown, suction type gas-liquid distributors 3 are arranged on the gas-liquid distribution tray 2 , and a plurality of gas-liquid distributors 3 are surrounded by a liquid phase cofferdam 4 . The liquid phase cofferdam in the middle is circular, and the circular liquid phase cofferdam is surrounded by fan-shaped liquid phase cofferdams. The height of the liquid phase cofferdam is 1.5 times the height from the bottom edge of the bubble cap to the gas-liquid distribution plate 2 . When the gas-liquid distribution plate tray 2 is horizontally deflected, a small area of ​​relatively independent liquid surface will be maintained between the liquid phase cofferdams 4 to ensure that the multiple gas-liquid distributors 3 in the liquid phase cofferdams 4 have the corresponding Adapt to the liquid level, better play a role.

Abstract

The invention provides a gas-liquid distribution plate capable of reducing horizontal susceptibility. The gas-liquid distribution plate comprises a tray; a proper amount of gas-liquid distributors are arranged on the tray; liquid phase cofferdams are arranged on the tray and divide the tray into a plurality of zones with an area smaller than that of the tray. In use of the gas-liquid distribution plate provided by the invention, a liquid phase preliminary distributor is preferably arranged on the upper part of the gas-liquid distribution plate, and when the gas-liquid distribution plate has horizontal shift, the liquid phase cofferdams can form a plurality of liquid surfaces with a small area to allow the gas-liquid distributors in every cofferdam to continue playing a role, thereby improving a gas-liquid mixing effect.

Description

technical field [0001] The invention relates to a gas-liquid distribution plate with reduced level sensitivity, which belongs to the field of petrochemical industry, and is especially suitable for uniform distribution of gas-liquid two-phase flow in a fixed-bed hydrogenation reactor. Background technique [0002] With the continuous improvement of the technical level of petrochemical machinery, the tower equipment in the oil refining industry is gradually becoming larger and more complex. At present, the diameter of the fixed-bed hydrogenation reactor can exceed 5000mm, but the ensuing reaction engineering problems such as large radial temperature difference and hot spots in the catalyst bed are gradually emerging. [0003] The ideal state of mass transfer in a fixed-bed hydrogenation reactor is that the raw material oil is evenly distributed on the surface of the catalyst particles, and the hydrogen gas passes through the gaps in the catalyst bed. Therefore, hydrogen needs...
