Description

Technical Field

[0001] This utility model relates to the field of gas-liquid distributor technology, and specifically to a gas-liquid distributor. Background Technology

[0002] Graphite packed towers are packed towers made with graphite as the base material, primarily used for gas-liquid contact mass transfer processes. They typically consist of tower sections, a liquid distributor, trays, end caps, and packing. The tower sections are hollow, impermeable graphite cylinders, while the packing is placed on support plates, arranged either randomly or in a modular fashion. A packing pressure plate is usually installed above the packing to prevent it from being blown away by the rising gas flow.

[0003] The working principle of a graphite packed tower is that liquid is sprayed from the top of the tower onto the packing material via a liquid distributor and flows down along the surface of the packing. Simultaneously, gas is introduced from the bottom of the tower, distributed by a gas distributor, and then comes into countercurrent contact with the liquid. Mass transfer occurs between the gas and liquid phases through close contact within the voids of the packing layer, achieving the exchange of substances.

[0004] In existing graphite collectors and distributors, a cylindrical tube with the same outer diameter as the circular base is mounted on a circular base. This tube contains a riser pipe and a liquid distribution pipe. The riser pipe has a slightly larger diameter, a closed top, and an air vent at the top. The liquid distribution pipe has elongated slots along its height to allow liquid to pass through. This graphite collector and distributor offers some operational flexibility and corrosion resistance. However, the separately installed riser pipe occupies a portion of the cross-sectional area, affecting the uniformity of the geometric arrangement of the distribution points and causing insufficient wetting, thus failing to guarantee a uniform distribution of the gas and liquid phases within the tower. Utility Model Content

[0005] To address the problem of uneven liquid collection and gas distribution in packed towers, resulting in insufficient wetting, this invention provides a gas-liquid distributor, fixedly installed between the upper and lower tower sections. It includes a liquid collecting cylinder, a base plate, and a cyclone tube. The base plate has multiple through holes, and the cyclone tube is fixedly installed inside the through holes. The liquid collecting cylinder is installed on the outside of the base plate.

[0006] As a preferred embodiment, the cyclone tube has multiple oblique cuts on its sidewall.

[0007] As a preferred embodiment, the diameter of the chassis is larger than the diameter of the upper tower section.

[0008] As a preferred embodiment, the height of the liquid collecting cylinder is 20 to 30 mm higher than the height of the oblique cut.

[0009] As a preferred embodiment, a sealing layer is provided between the chassis and the lower tower section.

[0010] As a preferred embodiment, the diameter of the cyclone tube is not less than 15 mm.

[0011] As a preferred embodiment, the cyclone tube is a graphite cyclone tube.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model optimizes the structure of the packed tower body by forming an independently existing liquid collector and improves the design of the distributor. The liquid collecting cylinder facilitates the centralized collection of absorbent liquid inside the tower, ensuring that all liquid inside the packed tower can be effectively collected into the liquid collector. This design reduces liquid retention inside the tower, improving absorption efficiency and the tower's processing capacity.

[0014] 2. This utility model uses a tangentially open cyclone tube as a gas-liquid distribution tube, which allows the liquid phase to flow downwards close to the inner wall of the cyclone tube, while the gas phase can rise in the middle of the cyclone tube, so that the gas and liquid phases can be fully mixed and mass transferred, which helps to generate a cyclone effect and thus improve the overall performance of the tower.

[0020] To illustrate the features of this utility model, the following description, in conjunction with the accompanying drawings and embodiments, will further explain this utility model.

[0021] Example:

[0022] Please see Figure 1 and Figure 2 This utility model provides a gas-liquid distributor, which is fixedly installed between the upper column section 1 and the lower column section 3. It includes a liquid collecting cylinder 21, a base plate 22 and a cyclone tube 23. The base plate 22 has multiple through holes, and the cyclone tube 23 is fixedly installed in the through holes. The liquid collecting cylinder 21 is installed on the outside of the base plate 22. When used as a redistributor, it collects the liquid in the upper column section 1 into the liquid collector and prevents it from flowing out.

[0023] To ensure the liquid phase adheres tightly to the inner wall of the hydrocyclone and forms a liquid film, while the gas phase rises in the middle of the hydrocyclone, allowing for thorough mixing and mass transfer between the two phases, multiple oblique cuts 24 are made on the side wall of the hydrocyclone 23. To ensure that the collected liquid can fully enter the hydrocyclone, in this embodiment, the height of the liquid collecting cylinder 21 is 30 mm higher than the height of the oblique cuts 24. To ensure sufficient space for gas phase flow, the diameter of the hydrocyclone 23 is not less than 15 mm, and in this embodiment, it is 20 mm. Furthermore, the hydrocyclone 23 is made of graphite.

[0024] In addition, this embodiment has been adapted and improved. Specifically, the diameter of the chassis 22 is 10 mm larger than the diameter of the upper column section 1, and a sealing layer is provided between the chassis 22 and the lower column section 3 to prevent any liquid that may not be collected by the liquid collector from flowing along the column wall and affecting the distribution of the liquid.

[0025] This embodiment optimizes the structure of the packed tower by forming an independent liquid collector and improves the design of the distributor. The use of a collecting cylinder facilitates the centralized collection of absorbent within the tower, ensuring that all liquid within the packed tower is effectively collected into the liquid collector. This design reduces liquid retention within the tower, improving absorption efficiency and the tower's processing capacity. The use of a tangentially open cyclone tube as the gas-liquid distribution tube allows the liquid phase to flow downwards close to the inner wall of the cyclone tube, while the gas phase can rise in the middle of the cyclone tube. This allows for thorough mixing and mass transfer between the gas and liquid phases, contributing to the swirling effect and thus improving the overall performance of the tower.
