[0002] According to Chinese Patent No. CN222142152U, this utility model provides a fluid-stabilizing floating valve tray, relating to the field of tray technology. It includes a tray body with a valve hole on its surface, a connecting block on the surface of the valve hole, a valve cover on the surface of the connecting block, a flow divider groove inside the valve cover, an exhaust groove inside the connecting block, a valve leg at the bottom of the connecting block, a vent hole on the surface of the valve leg, a guide block on the surface of the valve leg, and a guide groove on the surface of the valve hole. The use of a valve cover, flow divider groove, exhaust groove, and vent hole, with the valve cover shaped like an umbrella, allows airflow to enter the valve cover and concentrate towards the top of the valve cover, then be divided by the flow divider groove to prevent concentrated exhaust. The airflow is dispersed and discharged through the exhaust groove, forming a vortex within the exhaust groove, causing the airflow to spray out like mist, making the airflow more dispersed and uniform, thus stabilizing the fluid. Furthermore, the vent hole on the surface of the valve leg allows airflow to also be discharged.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] 1. Existing tray systems have certain shortcomings in liquid distribution. Some trays have poorly designed liquid distributors, resulting in uneven liquid distribution on the trays, insufficient gas-liquid contact, and thus reduced mass transfer efficiency. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a tray device with uniform liquid distribution.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tray device with uniform liquid distribution function, comprising a tray body, a through hole on the surface of the tray body, a downcomer at the bottom of the tray body, a liquid distributor base at the top of the tray body, a positioning plate at the top of the liquid distributor base, and a liquid distributor main pipe at the top of the liquid distributor base.

[0007] Preferably, the top of the tray body is provided with a V-shaped guide block, and the V-shaped guide block is welded to the top of the tray body, and the V-shaped guide block is arranged in a circumferential pattern.

[0008] Preferably, the top of the tray body is provided with an overflow weir, and the overflow weir and the tray body are connected by a snap-fit ​​mechanism.

[0009] Preferably, the overflow weir has an overflow outlet on one side, and the overflow outlets are distributed in a matrix, with each overflow outlet having the same diameter.

[0011] Preferably, liquid distributor branch pipes are provided on both sides of the liquid distributor main pipe, and the liquid distributor branch pipes on both sides are welded to the liquid distributor main pipe.

[0012] Preferably, the top of the positioning plate is provided with a positioning bolt, and the positioning bolt is threadedly connected to the top of the positioning plate.

[0013] Beneficial effects

[0014] In this invention, a V-shaped flow guide block is provided at the top of the tray body. The height of the flow guide block gradually decreases from the center to the edge of the tray body, conforming to the flow trend of liquid on the tray and facilitating better liquid diffusion. The V-shaped structural design acts like a flow guide "arrow," more precisely guiding the flow direction of the liquid. Compared to flow guide blocks of ordinary shapes, the V-shape can concentrate the liquid in a specific direction, causing the liquid to flow along a predetermined path on the tray, avoiding disorderly liquid spread, thereby significantly improving the uniformity of liquid distribution on the tray, promoting more complete gas-liquid contact, and effectively improving mass transfer efficiency. The gradual decrease in the height of the flow guide block from the center to the edge of the tray body perfectly matches the natural flow trend of liquid diffusion from the center to the edge on the tray. Under the action of gravity, the liquid flows more smoothly along this height difference, reducing local liquid accumulation caused by flow resistance, and making the liquid diffusion more uniform throughout the entire tray.

[0015] In this invention, a liquid outlet is provided at the bottom of the liquid distributor base, allowing for uniform distribution of liquid across the base. This ensures that the liquid flows out relatively evenly from the inlet branch pipe, achieving a more uniform dispersion upon leaving the liquid distributor. This prevents excessive concentration or sparse distribution of liquid in certain local areas, ensuring that the liquid enters the tray in a relatively balanced state from the initial stage, thereby improving the overall mass transfer efficiency. The evenly flowing liquid forms a more uniform liquid layer on the tray, ensuring sufficient contact with the rising gas. The increased and more uniform gas-liquid contact area makes the mass transfer process more efficient, contributing to improved product quality and production efficiency.

[0016] In this invention, multiple overflow ports are evenly distributed on one side of the overflow weir. This allows for the timely discharge of excess liquid, ensuring a stable liquid volume on the tray and preventing excessive liquid from affecting the uniformity of liquid distribution. The even distribution of multiple overflow ports on one side provides multiple uniform and orderly discharge channels for the liquid. This helps avoid localized disturbances caused by concentrated liquid discharge from a single point, resulting in a smoother liquid discharge process and reducing interference with the overall gas-liquid flow order on the tray. Because the overflow ports are evenly distributed, the liquid flow rate distributed to each overflow port is relatively balanced, reducing the risk of malfunction due to excessive flow at a single overflow port.

[0023] 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.

[0024] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0026] Reference Figure 1-4A tray device with uniform liquid distribution function includes a tray body 1, with through holes 2 on the surface of the tray body 1, and V-shaped guide blocks 3 on the top of the tray body 1, which are welded to the top of the tray body 1. The V-shaped guide blocks 3 are arranged in a circumferential pattern. An overflow weir 4 is provided on the top of the tray body 1, and the overflow weir 4 is snap-fitted to the tray body 1. An overflow port 12 is provided on one side of the overflow weir 4, and the overflow ports 12 are arranged in a matrix, with each overflow port 12 having the same diameter. A liquid distributor base 6 has liquid outlet holes 11 at the bottom, and the liquid outlet holes 11 are arranged in a matrix. The arrangement includes liquid distributor branch pipes 8 on both sides of the liquid distributor main pipe 9, which are welded to the liquid distributor main pipe 9. The top of the positioning plate 7 is provided with a positioning bolt 10, which is threaded to the top of the positioning plate 7. The bottom of the tray body 1 is provided with a downcomer 5, and the top of the tray body 1 is provided with a liquid distributor base 6. The top of the liquid distributor base 6 is provided with a positioning plate 7, and the top of the liquid distributor base 6 is provided with the liquid distributor main pipe 9. The positioning plates 7 are set on both sides of the liquid distributor main pipe 9 and are parallel to the liquid distributor main pipe 9.

[0027] A V-shaped flow guide block 3 is provided at the top of the tray body 1. The height of the flow guide block gradually decreases from the center of the tray body to the edge, which conforms to the flow trend of the liquid on the tray and helps the liquid diffuse better. The V-shaped structural design is like a "flow guide arrow", which can more accurately guide the flow direction of the liquid. Compared with the flow guide block of ordinary shape, the V-shape can converge the liquid in a specific direction, so that the liquid flows on the tray along a preset path, avoiding disorderly liquid spread, thereby significantly improving the uniformity of liquid distribution on the tray, promoting more complete gas-liquid contact, and effectively improving mass transfer efficiency. The height of the flow guide block gradually decreases from the center of the tray body to the edge, perfectly matching the natural flow trend of liquid diffusion from the center to the edge on the tray. Under the influence of gravity, the liquid flows more smoothly along this height difference, reducing localized liquid accumulation caused by flow resistance and making the liquid diffusion more uniform across the entire tray. A liquid outlet 11 is located at the bottom of the liquid distributor base 6, evenly distributed across the base, allowing the liquid to flow out relatively evenly from the inlet branch pipe. This ensures that the liquid is evenly dispersed upon leaving the liquid distributor, preventing excessive concentration or thinning in certain local areas and ensuring that the liquid enters the tray in a relatively balanced state from the initial stage, thereby improving overall mass transfer efficiency. The evenly flowing liquid forms a more uniform liquid layer on the tray, fully contacting the rising gas. The increased and more uniform gas-liquid contact area makes the mass transfer process more efficient, contributing to improved product quality and production efficiency. Multiple overflow ports 12 are evenly distributed on one side of the overflow weir 4, allowing for timely discharge of excess liquid and ensuring a stable liquid volume on the tray, preventing excessive liquid from affecting the uniformity of liquid distribution. The multiple overflow ports 12 evenly distributed on one side provide multiple uniform and orderly discharge channels for the liquid. This helps avoid local disturbances caused by concentrated liquid discharge from a certain point, making the liquid discharge process more stable and reducing interference with the overall gas-liquid flow order on the tray. Since the overflow ports 12 are evenly distributed, the liquid flow rate shared by each overflow port 12 is relatively balanced, reducing the risk of failure of a single overflow port 12 due to excessive flow. Specific Implementation Example 2:

[0029] Reference Figure 1-4 The V-shaped guide block 3 is connected to the tray body by a threaded connection. The threaded connection is simple to operate. During installation, simply align the V-shaped guide block 3 with the threaded hole of the tray body and screw it in. No complicated tools or professional skills are required, saving installation time. Disassembly is done by simply rotating in the reverse direction. Disassembly can be completed quickly when the equipment is inspected, maintained, or the guide block needs to be replaced.

[0030] In summary:

[0031] 1. A V-shaped flow guide block 3 is installed at the top of the main tray 1. The height of the flow guide block gradually decreases from the center to the edge of the tray, conforming to the flow trend of the liquid on the tray and facilitating better liquid diffusion. The V-shaped structure acts like an "arrow" to guide the flow, more precisely directing the liquid's flow direction. Compared to ordinary flow guide blocks, the V-shape can concentrate the liquid in a specific direction, allowing it to flow along a predetermined path on the tray, avoiding disorderly liquid spread. This significantly improves the uniformity of liquid distribution on the tray, promotes more thorough gas-liquid contact, and effectively improves mass transfer efficiency. The gradual decrease in the height of the flow guide block from the center to the edge perfectly matches the natural flow trend of liquid diffusion from the center to the edge on the tray. Under the influence of gravity, the liquid flows more smoothly along this height difference, reducing local liquid accumulation caused by flow resistance and making the liquid diffusion more uniform throughout the entire tray.

[0032] 2. A liquid outlet hole 11 is provided at the bottom of the liquid distributor base 6, allowing the liquid to be evenly distributed on the base 6. This ensures that the liquid flows out relatively evenly from the inlet branch pipe, achieving a more uniform dispersion of the liquid upon leaving the liquid distributor. This avoids excessive concentration or thinning of the liquid in certain local areas, ensuring that the liquid enters the tray in a relatively balanced state from the initial stage, thereby improving the overall mass transfer efficiency. The evenly flowing liquid forms a more uniform liquid layer on the tray, making full contact with the rising gas. The increased and more uniform gas-liquid contact area makes the mass transfer process more efficient, contributing to improved product quality and production efficiency.

[0033] 3. Multiple overflow ports 12 are evenly distributed on one side of the overflow weir 4, which can promptly discharge excess liquid, ensuring the stability of the liquid volume on the tray and avoiding the impact of excessive liquid on the uniformity of liquid distribution. The multiple overflow ports 12 evenly distributed on one side provide multiple uniform and orderly discharge channels for the liquid. This helps to avoid local disturbances caused by the concentrated discharge of liquid from one point, making the liquid discharge process more stable and reducing interference with the overall gas-liquid flow order on the tray. Because the overflow ports 12 are evenly distributed, the liquid flow rate distributed by each overflow port 12 is relatively balanced, reducing the risk of failure of a single overflow port 12 due to excessive flow.
