And a gas phase channel is additionally arranged in the liquid redistributor, so that the circulation amount of a gas phase is greatly increased, and the gas resistance is reduced.

Description

Technical Field

[0001] The utility model relates to chemical equipment, in particular to a packing tower. Background Art

[0002] A packed tower is a mass transfer device that uses the packing inside the tower as the contact component between the gas and liquid phases. A liquid redistributor is installed between the upper and lower packing layers to achieve liquid redistribution. However, traditional liquid redistributors allow the liquid and gas phases to pass through the same channel, which reduces the flow rate of the gas phase and increases the resistance of the gas in the tower. Utility Model Content

[0003] The utility model provides a packing tower, in which a gas phase channel is newly added in a liquid redistributor, thereby greatly increasing the flow rate of the gas phase and reducing the gas resistance.

[0004] The technical solution of this utility model:

[0005] A packed tower comprises a tower body, an upper packing layer, a lower packing layer, and a liquid redistributor, wherein the upper packing layer is installed in the tower body at the upper part, the lower packing layer is installed in the tower body at the lower part, and the liquid redistributor is installed in the tower body and is located between the upper and lower packing layers; the liquid redistributor is composed of a liquid collecting tray and a plurality of liquid separating cups; the liquid collecting tray is cylindrical with a sealed bottom, the upper end of the liquid collecting tray is seamlessly connected to the inner wall of the tower body, a gap I is left between the side wall and the inner wall of the tower body, and a gap II is left between the lower end and the inner wall of the tower body; the side wall of the liquid collecting tray is opened with holes, and the holes, gaps I and II form a gas phase channel; the liquid separating cups are distributed and installed at the bottom of the liquid collecting tray and are located below the holes on the side wall of the liquid collecting tray. BRIEF DESCRIPTION OF THE DRAWINGS

[0006] Figure 1 It is a schematic diagram of the local structure of the packed tower.

[0007] Figure 2 It is a schematic diagram of the gas-liquid flow in the local structure of the packed tower.

[0008] In the figure, there are a tower body 1, a lower annular boss 1-1, an upper filler 2, an upper filler support plate 3, a liquid collecting tray 4, an upper annular boss 4-1, a hole 4-2, a liquid separating cup 5, and a gas phase channel 6. DETAILED DESCRIPTION

[0009] like Figure 1-2 A packed tower is shown, comprising a tower body 1, an upper packing layer 2, a lower packing layer, and a liquid redistributor. The upper packing layer 2 is installed in the tower body 1 at the upper position (supported on an upper packing support plate 3), the lower packing layer is installed in the tower body at the lower position, and the liquid redistributor is installed in the tower body 1 between the upper packing layer 2 and the lower packing layer.

[0010] The liquid redistributor consists of a liquid collecting tray 4 and a number of liquid separating cups 5; the liquid collecting tray 4 is cylindrical with a sealed bottom, the upper end of the liquid collecting tray 4 is seamlessly connected to the inner wall of the tower body 1 (the outer periphery of the upper end of the liquid collecting tray 4 has an upper annular boss 4-1, the inner wall of the tower body 1 has a lower annular boss 1-1, and the upper annular boss 4-1 is supported on the lower annular boss 1-1), and a gap II is left between the lower end and the inner wall of the tower body 1. The side wall of the liquid collecting tray 4 has a hole 4-2, and the hole 4-2 and the gap I and gap II form a gas phase channel 6. The liquid separating cups 5 are distributed and installed at the bottom of the liquid collecting tray 4 and below the hole 4-2 on the side wall of the liquid collecting tray 4.

[0011] The above embodiments are intended only to illustrate the technical concepts and features of the utility model. Their purpose is to enable those familiar with the art to understand the content of the utility model and implement it accordingly. They are not intended to limit the scope of protection of the utility model. Any equivalent changes or modifications made based on the spirit of the utility model are intended to be covered by the scope of protection of the utility model.
