It includes a tray with downcomers snapped onto its upper surface. A tube body is fixedly connected to the inner surface of the downcomer. The upper surface of the tube body overlaps with the lower surfaces of two arc-shaped rods, which overlap each other. A covering cloth is fixedly connected to the surface of each of the two arc-shaped rods, and the lower surfaces of the two covering cloths overlap with the upper surfaces of the downcomers. This multi-downcomer tray with uniform gas-liquid phase distribution, by incorporating a rotating shaft, gears, connecting rods, arc-shaped rods, and covering cloths, allows the two covering cloths to be unfolded to cover an arc-shaped area. Simultaneously, the two arc-shaped rods connect to switch between circular and arc-shaped areas. Furthermore, retracting the covering cloths achieves the switching between arc-shaped and circular areas. This allows the device to meet the needs of field use, improves its versatility, and further enhances its practical value.
[0003] In the above-mentioned and existing technologies, the height of the overflow weir is fixed when the tower tray is installed. However, the required height of the overflow weir varies greatly when the tower tray is used in different fields, and it is impossible to change the height of the overflow weir according to different fields. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies that cannot adjust the height of the overflow weir according to different fields, and to propose a high-efficiency gas distribution tray.

[0006] Preferably, the multiple through holes on the surface of the tray body are all located in the middle of the tray body, and the liquid receiving plate is located on the edge of the tray body, and the liquid receiving plate is integrally formed with the tray body.
[0007] Preferably, the overflow weir is fixed to the surface of the tray body by three fixing bolts, and the movable plate is installed on the top surface of the overflow weir.
[0008] Preferably, the two chutes are provided on the surface of the overflow weir away from the main body of the tray, and the two chutes are evenly provided at both ends of the overflow weir.

[0010] Preferably, the insertion holes on the surface of the slide groove correspond one-to-one with the insertion holes on the surface of the slider, and the screws all pass through the insertion holes on the surfaces of the slide groove and the slider.
[0011] Preferably, the four guide grooves are equally spaced on the top surface of the overflow weir, and the positions of the guide rods correspond one-to-one with the positions of the guide grooves. The four guide rods are integrally formed with the movable plate, and all four guide rods are installed in the four guide grooves.
[0012] Beneficial effects
[0013] In this invention, a guide rod of a movable plate is installed in the guide groove of the overflow weir, and both sliders of the movable plate are installed in the slide groove of the overflow weir. A screw passes through the insertion hole of the movable plate and the overflow weir to fix the movable plate at a fixed height. When it is necessary to change the height of the overflow weir, the screw can be removed, and the movable plate can be moved up or down using the handle. When the movable plate is moved to the overflow weir height of the desired area, the screw can be inserted into the slide groove and the insertion hole of the slider again and fixed with a fastener to fix the movable plate at the desired height. The height of the overflow weir is increased by using the movable plate, which solves the disadvantage of not being able to change the height of the overflow weir according to different areas.

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 1-5 A high-efficiency gas distribution tray includes a tray body 1. The surface of the tray body 1 has multiple through holes 2, and each through hole 2 is equipped with a float valve 3. A liquid receiving plate 4 is located on the top surface of the tray body 1. An overflow weir 5 is located on one side of the tray body 1. A movable plate 6 is located on the top of the overflow weir 5. Two grooves 9 are located on the surface of the overflow weir 5. Two sliders 10 are located on the surface of the movable plate 6. A handle 11 is located between the two sliders 10. A screw 12 is located on one side of the overflow weir 5. Multiple insertion holes 13 are located on the surfaces of the two grooves 9 and the two sliders 10. Four guide grooves 8 are located on the top surface of the overflow weir 5. Four guide rods 7 are located on the bottom surface of the movable plate 6. The multiple through holes 2 on the surface of the tray body 1 are all located in the middle of the tray body 1. The liquid receiving plate 4 is located at the edge of the tray body 1 and is integrally formed with the tray body 1. The overflow weir 5 is connected by three fixed... The fixed bolts are fixed to the surface of the tray body 1, and the movable plate 6 is installed on the top surface of the overflow weir 5. Two sliding grooves 9 are set on the surface of the overflow weir 5 away from the tray body 1, and the two sliding grooves 9 are evenly set at both ends of the overflow weir 5. The positions of the two sliders 10 correspond one-to-one with the positions of the two sliding grooves 9, and the sliders 10 are all installed in the sliding grooves 9. The handrail 11 is parallel to the two sliders 10, and the two sliders 10 and the handrail 11 are integrally formed with the overflow weir 5. The insertion holes 13 set on the surface of the sliding grooves 9 correspond one-to-one with the insertion holes 13 set on the surface of the sliders 10. The screws 12 all pass through the insertion holes 13 on the surfaces of the sliding grooves 9 and the sliders 10. Four guide grooves 8 are set at equal intervals on the top surface of the overflow weir 5, and the positions of the guide rods 7 correspond one-to-one with the positions of the guide grooves 8. The four guide rods 7 are integrally formed with the movable plate 6, and the four guide rods 7 are all installed in the four guide grooves 8.
[0025] The tray body 1 is fixed inside a multi-stage tower reactor, distillation column, extraction column, etc., by eleven fixing bolts. Multiple through holes 2 are provided in the middle of the tray body 1, and a float valve 3 is installed in each through hole 2. The float valve 3 is installed in the through hole 2 of the tray body 1 via its own valve foot. When there is no rising vapor phase, the float valve 3 is closed on the tray body 1. When vapor phase rises, the float valve 3 is impacted by the vapor flow and opens upwards. The opening degree increases with the amount of vapor phase. The rising vapor phase passes through the through hole 2 and is controlled by the action of the float valve 3. The liquid phase is dispersed horizontally downwards, bubbling out through the liquid layer to ensure full contact between the vapor and liquid phases. The overflow weir 5 is fixed to the left end of the tray body 1 by three fixing bolts, with the bolts positioned at the bottom of the overflow weir 5. The receiving plate 4 is located at the right end of the top surface of the tray body 1. When the liquid phase falls through the overflow weir 5 at the top of the tray body 1, it lands on the receiving plate 4 and is evenly distributed onto the tray body 1. The overflow weir 5 prevents a certain amount of liquid phase from remaining on the tray body 1, allowing it to interact with the liquid in the overflow weir. The gas phase dispersed by the float valve 3 on the main body of the tray 1 undergoes thorough gas-liquid mixing. The guide rod 7 of the moving plate 6 is installed in the guide groove 8 of the overflow weir 5, and the two sliders 10 of the moving plate 6 are both installed in the slide grooves 9 of the overflow weir 5. The moving plate 6 is fixed at a fixed height by the screw 12 passing through the insertion hole 13 of the moving plate 6 and the overflow weir 5. When it is necessary to change the height of the overflow weir 5 to increase the amount of liquid phase remaining on the main body of the tray 1, the fixing part of the screw 12 can be unscrewed, and the screw 12 can be removed from the two slide grooves 9 and the two sliders 10. When the screw 12 is pulled out of the insertion hole 13, the movable plate 6 can move up and down. The movable plate 6 can be lifted up by the handle 11. When the movable plate 6 is moved to the required height of the overflow weir 5 in the required area, the screw 12 can be inserted into the insertion hole 13 of the slide groove 9 and the slider 10 again, and the screw 12 can be fixed with the fastener, so that the movable plate 6 is fixed at the required height. This increases the overall height of the overflow weir 5 by the movable plate 6, so that the liquid phase remaining on the tray body 1 can be increased to adapt to different areas. Specific Implementation Example 2:
[0027] Reference Figure 1-5 A high-efficiency gas distribution tray, further based on the basic structure in Specific Embodiment 1, according to Appendix Figure 1 It can be clearly seen that the top surface of the float valve 3 installed in the through hole 2 on the surface of the tray body 1 has four cuts and guide holes. The top of the traditional float valve 3 is a mass transfer blind zone, which makes the gas-liquid contact above the top of the float valve 3 insufficient. In contrast, the traditional float valve 3 can eliminate the bubbling blind zone at the top of the valve by adding guide holes, refine the bubbles blown out by the gas around the circular valve, and at the same time increase the push on the liquid above the tray, reducing the liquid gradient on the tray. By setting the elongated liquid flow guide hole at the front valve leg, the residence time of the liquid in the stagnation zone is reduced, thereby improving the mass transfer efficiency and processing capacity of the tray.
[0028] In summary:
[0029] 1. The guide rod 7 of the movable plate 6 is installed in the guide groove 8 of the overflow weir 5, and the two sliders 10 of the movable plate 6 are installed in the slide groove 9 of the overflow weir 5. The movable plate 6 is fixed at a fixed height by passing through the insertion hole 13 of the movable plate 6 and the overflow weir 5 with the screw 12. When it is necessary to change the height of the overflow weir 5, the screw 12 can be taken out, and the movable plate 6 can be moved up or down by the handle 11. When the movable plate 6 moves to the overflow weir 5 height of the required area, the screw 12 can be passed through the slide groove 9 and the insertion hole 13 of the slider 10 again and fixed with the fastener, so that the movable plate 6 is fixed at the required height. The height of the overflow weir 5 is increased by the movable plate 6, which solves the disadvantage of not being able to change the height of the overflow weir 5 according to different areas.
