[0003] The above-mentioned solutions and existing technical solutions have poor improvement in liquid uniformity, and the above-mentioned solutions have high structural complexity. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tray structure that enhances the uniformity of liquid distribution.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a tray structure with enhanced liquid distribution uniformity, comprising a tray body, wherein a tray grid is uniformly arranged on the surface of the tray body, and an air inlet straight pipe and an annular air pipe are provided at the bottom of the tray body, and a vertical air guide pipe is provided between the air inlet straight pipe, the annular air pipe and the tray grid, and an air inlet port is provided at the end of the air inlet straight pipe.

[0006] Preferably, the tray grid consists of multiple parallel pipes with closed ends, and the tray grid and the tray body are welded and fixed together, with open ports on both sides of the pipes of the tray grid.

[0007] Preferably, the open port is a horn-shaped port extending from the inside out, and the open port and the inner cavity of the tower plate grid are interconnected.

[0008] Preferably, the tower plate grid is interconnected with the vertical air guide pipe, the straight air inlet pipe, and the annular air pipe, and the straight air inlet pipe and the annular air pipe are connected to an external air source through the air inlet port.

[0009] Preferably, the end of the air intake port is a flange, and the surface of the air intake port is sealed with an O-ring.

[0010] Preferably, the inner surface of the horn of the open port is spirally provided with a groove with a rectangular cross-section, and the open ports are arranged at equal intervals on the surface of the tower plate grid.

[0011] Preferably, a vertical air duct is provided at the intersection of the horizontal projections of the straight intake pipe and the annular air pipe to connect the two.

[0012] Beneficial effects

[0013] In this invention, multiple parallel, closed-end pipe-type tray grids are evenly arranged on the surface of the tray body, and the open ports of the grids are designed with a horn shape and spiral grooves to effectively disperse the gas evenly onto the liquid surface. This ensures that the liquid is fully dispersed after impacting the tray grids, avoiding the accumulation or channeling of liquid on the tray, thereby achieving uniform liquid distribution within the tower. This uniform liquid distribution not only improves the contact efficiency of each operating unit within the tower but also reduces equipment blockage and operational instability caused by uneven liquid distribution.

[0014] In this invention, through the rational arrangement of the straight inlet pipe, the annular gas pipe, and the vertical gas guide pipe, the gas can be efficiently injected outward through the open port of the tower tray grid, forming a strong gas turbulence. The secondary turbulence effect causes the liquid inside the tower to be subjected to multiple impacts, resulting in finer liquid atomization and mixing, thereby significantly improving the efficiency of gas-liquid mixing. It accelerates the material transfer rate, improves the efficiency of the reaction or separation process, and helps to improve the production capacity and process stability of the entire chemical tower.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0024] Reference Figure 1-4 A tray structure for enhanced liquid distribution uniformity includes a tray body 2. A tray grid 3 is uniformly distributed on the surface of the tray body 2. The tray grid 3 consists of multiple parallel, closed-end pipes, which are welded and fixed to the tray body 2. Open ports 7 are provided on both sides of the pipes of the tray grid 3. Each open port 7 is a flared port extending from the inside out, and the open ports 7 are interconnected with the inner cavity of the tray grid 3. A rectangular groove is spirally formed on the inner surface of the flared port 7, and the open ports 7 are evenly spaced on the surface of the tray grid 3. The bottom of the tray body 2 is provided with an air inlet straight pipe 4 and an annular air pipe 6. A vertical air guide pipe 5 is provided between the air inlet straight pipe 4, the annular air pipe 6 and the tray grid 3. The tray grid 3 is interconnected with the air inlet straight pipe 4 and the annular air pipe 6 through the vertical air guide pipe 5. The air inlet straight pipe 4 and the annular air pipe 6 are connected to an external air source through the air inlet port 1. A vertical air guide pipe 5 is provided at the intersection of the horizontal projections of the air inlet straight pipe 4 and the annular air pipe 6 to connect the two. The end of the air inlet straight pipe 4 is provided with an air inlet port 1. The end of the air inlet port 1 is a flange, and the surface of the air inlet port 1 is sealed with an O-ring.

[0025] During use, the entire tray is placed inside the chemical tower. Then, the entire device is connected to the gas source via the flange at inlet port 1. The gas source can be an industrial gas station or a gas cylinder, and corresponding valves are installed between them. When the chemical tower is undergoing reaction, the introduced gas must ensure that it does not react with the raw materials or byproducts inside the tower. Inert gases are preferred. The gas enters through the straight inlet pipe 4 into the annular gas pipe 6, the vertical gas guide pipe 5, and the tray grid 3. After the chemical liquid enters, it impacts and disperses on the tray grid 3. Simultaneously, the external gas... Gas is ejected outward through the open port 7 on the surface of the tray grid 3. Through the horn-shaped open port 7, the gas diffuses outward and further impacts the liquid inside the tower, causing secondary turbulence. Afterward, part of the liquid inside the tower is impacted onto the surface of the tray grid 3, while the other part is further dispersed by the gas impact, forming gas turbulence. This accelerates the mixing efficiency of the liquid inside the tower, and the mixing amount per unit time is much greater than that of mixing with a single tray grid 3. In the current test, the improvement in mixing amount exceeds 30%. Specific Implementation Example 2:

[0027] Based on the technical solution of Specific Embodiment 1, in a further technology, the annular gas pipe 6 has 6-20 sets of vertical gas guide pipes 5 in a uniform array, which can further promote the mixing of liquids in the tower, but will increase costs to a certain extent. At the same time, the gas inlet port 1 can eliminate the flange interface and adopt a quick-connect pipe interface to ensure gas sealing.

[0028] In summary:

[0029] 1. By uniformly setting multiple parallel, closed-end pipe-type tray grids 3 on the surface of the tray body 2, and using a horn-shaped design and spiral grooves at the open ports 7 of the grids, the gas is effectively and uniformly dispersed to the liquid surface. This ensures that the liquid is fully dispersed after impacting the tray grids 3, avoiding the accumulation or channeling of liquid on the tray, thereby achieving uniform liquid distribution in the tower. The uniform liquid distribution not only improves the contact efficiency of each operating unit in the tower, but also reduces equipment blockage and operational instability caused by uneven liquid distribution.

[0030] 2. Through the rational arrangement of the straight inlet pipe 4, the annular gas pipe 6, and the vertical gas guide pipe 5, the gas can be efficiently injected outward through the open port 7 of the tower tray grid 3, forming a strong gas turbulence. The secondary turbulence causes the liquid inside the tower to be subjected to multiple impacts, resulting in finer liquid atomization and mixing, thereby significantly improving the efficiency of gas-liquid mixing. This accelerates the transfer rate of matter, improves the efficiency of the reaction or separation process, and helps to improve the production capacity and process stability of the entire chemical tower.
