Description

Technical Field

[0001] This utility model relates to the technical field of trough-type gas-liquid distributors, and in particular to a novel trough-type gas-liquid distributor. Background Technology

[0002] The trough-type gas-liquid distributor is a high-efficiency internal reflux liquid distribution device, consisting of a rectangular riser pipe, angle steel or channel steel liquid guide pipes, dovetail or channel steel liquid guide caps, a packing plate, a support ring, and a support beam. This distributor initially distributes the liquid into multiple streams through openings in the trough bottom, and then achieves uniform liquid distribution through channels and guide pipes in the trough bottom or wall, ensuring good wettability of the packing layer surface. Its structural design combines excellent distribution accuracy, operational flexibility, and anti-clogging capability, making it particularly suitable for separation processes with high gas-liquid loads and containing solid particles or high-viscosity materials. It is widely used in chemical, petrochemical, and other industries.

[0003] Currently, most tray-type gas-liquid distributors use a fixed orifice design for their liquid guide tubes, which has significant limitations: when processing liquids with different flow rates, viscosities, or solid contents, the orifice diameter cannot be flexibly adjusted, leading to uneven distribution or easy clogging. Especially under fluctuating operating conditions, the fixed orifice diameter makes it difficult to balance distribution accuracy and anti-clogging performance, affecting separation efficiency and increasing maintenance costs. Existing technologies lack convenient orifice diameter adjustment structures, limiting the adaptability of distributors under complex operating conditions. Therefore, a novel tray-type gas-liquid distributor is proposed. Utility Model Content

[0004] This utility model is a novel trough-type gas-liquid distributor proposed to overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a novel trough-type gas-liquid distributor, comprising a trough, wherein a plurality of matching air risers are fixedly connected to the top of the trough, and a plurality of through holes are provided on both sides of the outer surface of the plurality of air risers.

[0006] Both sides of the outer surface of the plurality of air risers are sealed and abutted by opening adjustment plates, and the opening adjustment plates are matched with two adjacent through holes. The plurality of opening adjustment plates are all installed with limit components between the outer wall of the adjacent air risers.

[0007] A crossbar is fixedly connected to the top of multiple opening adjustment plates on one side of the multiple air risers, and a movable frame is fixedly connected to the top of the multiple crossbars.

[0008] Both ends of the movable frame are equipped with two connecting rods, and a synchronous drive assembly is installed between the two connecting rods.

[0009] Furthermore, each of the aforementioned opening adjustment plates includes a valve plate, and the valve plate is sealed and slidably attached to one side of the outer wall of the riser pipe. Two adjustment holes are symmetrically opened on one side of the outer surface of the valve plate, extending to the other side. The adjustment holes match the through holes, and the diameters of the adjustment holes and the through holes are consistent. This symmetrical design can ensure a linear response to changes in flow rate during the adjustment process.

[0010] Furthermore, each of the aforementioned limiting components includes a slider, and the slider is fixedly connected to the valve plate. A guide rail is slidably connected to one side of the outer surface of the slider, and the guide rail is fixedly connected to the air riser. The guide rail and the slider cooperate to limit the movement, thereby ensuring the stability of the valve plate movement.

[0011] Furthermore, the movable frame includes multiple long rods, which are fixedly connected to the crossbars. The tops of the multiple long rods are all fixedly connected to a top rod. This rigid connection structure ensures the synchronization and stability of the transmission, and even in large-scale devices, it can ensure that all adjustment units move in unison, avoiding local adjustment lag.

[0012] Furthermore, both of the aforementioned two-bar linkages include a short connecting rod, which is rotatably connected to the top rod. The other end of the short connecting rod is rotatably connected to a long connecting rod, which facilitates the adjustment of the position of the movable frame.

[0013] Furthermore, the synchronous drive assembly includes a servo motor, and the drive end of the servo motor is fixedly connected to a main shaft. Both long connecting rods are fixedly sleeved on the outer surface of the main shaft, which can synchronously drive the two two-bar linkage assemblies to operate.

[0014] Furthermore, each of the multiple riser pipes is fixedly connected to a riser cap to ensure gas-liquid contact and improve mass transfer efficiency.

[0015] The beneficial effects of this utility model are:

[0016] In use, this novel tray-type gas-liquid distributor achieves stepless adjustment of the orifice diameter by incorporating a sliding orifice adjustment plate on the outer surface of the riser pipe. This innovative structure solves the technical problems of uneven liquid distribution and easy clogging inherent in traditional fixed-aperture distributors under fluctuating operating conditions. Multiple orifice adjustment plates are linked together via crossbars and a movable frame, and with the assistance of a two-bar linkage and synchronous drive assembly, ensures that all adjustment plates move synchronously and precisely, thereby guaranteeing consistency in the adjustment of each orifice. This design significantly improves the distributor's operational flexibility, enabling it to adapt to complex operating conditions such as varying flow rates, viscosities, and solid-containing media.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, a novel trough-type gas-liquid distributor is disclosed, including a trough 1. Multiple matching air risers 5 are fixedly connected to the top of the trough 1, and multiple through holes 15 are opened on both sides of the outer surface of the multiple air risers 5.

[0027] Multiple air risers 5 have sealing adjustment plates on both sides of their outer surfaces, and the adjustment plates match two adjacent through holes 15. Limiting components are installed between the multiple adjustment plates and the outer walls of adjacent air risers 5. Each adjustment plate includes a valve plate 9, which is slidably fitted onto one side of the outer wall of the air riser 5. Two symmetrical adjustment holes 7 extending to the other side are opened on one side of the outer surface of the valve plate 9, and these holes match the through holes 15 with the same diameter. Each limiting component includes a slider 10, which is fixedly connected to the valve plate 9. A guide rail 8 is slidably connected to one side of the outer surface of the slider 10, and the guide rail 8 is fixedly connected to the air riser 5. A matching sealing rubber is fixedly connected to one side of the outer surface of the valve plate 9. The rubber material is fluororubber, which has advantages such as high temperature resistance, chemical corrosion resistance, and strong physical and mechanical properties, making it suitable for this application and ensuring the sealing performance of the connection between the valve plate 9 and the outer wall of the air riser 5.

[0028] Multiple air risers 5 have multiple opening adjustment plates on one side that are fixedly connected to a crossbar 6. The top of the multiple crossbars 6 is fixedly connected to a movable frame. Both ends of the movable frame are equipped with two connecting rods. A synchronous drive assembly is installed between the two connecting rods. The movable frame includes multiple long rods 14, which are fixedly connected to the crossbars 6. The top of the multiple long rods 14 is fixedly connected to a top rod 13. Both two connecting rod assemblies include short connecting rods 12, which are rotatably connected to the top rod 13. The other end of the short connecting rod 12 is rotatably connected to a long connecting rod 11. The synchronous drive assembly includes a servo motor 2, and the drive end of the servo motor 2 is fixedly connected to a main shaft 3. Both long connecting rods 11 are fixedly sleeved on the outer surface of the main shaft 3. The short connecting rod 12 is rotatably connected to the top rod 13 and the long connecting rod 11 through a pin.

[0029] Each of the multiple air riser pipes 5 is fixedly connected to an air riser cap 4, which is fixed to the air riser pipe 5 by bolts, making it easy to disassemble and assemble.

[0030] Working principle: First, the entire assembly is installed on the packed tower. The slotted tray 1 is fixed inside the packed tower. The main shaft 3 penetrates the packed tower and is rotatably connected to it in a sealed manner. The servo motor 2 is installed on the outer wall of the packed tower via a mounting bracket. Figure 5 As shown;

[0031] During operation, the liquid first enters the tank 1 and is initially distributed through the through-holes 15 on the outer surface of the riser pipe 5. When it is necessary to adjust the liquid distribution, the servo motor 2 drives the long connecting rods 11 on both sides to rotate synchronously through the spindle 3, which in turn drives the short connecting rods 12 to move. The short connecting rods 12 drive the movable frame to move as a whole through the top rod 13. The movable frame is linked to all the opening adjustment plates through the long rod 14 and the cross rod 6. The valve plate 9 in the opening adjustment plate slides smoothly along the outer wall of the riser pipe 5 under the guidance of the slider 10 and the guide rail 8. The adjustment hole 7 on the valve plate 9 and the through-hole 15 on the riser pipe 5 are relatively displaced, and the effective flow area of ​​the through-hole 15 is continuously adjusted by changing the overlapping area of ​​the two. When the adjustment hole 7 and the through-hole 15 are completely overlapped, the flow area is the largest; when they are partially overlapped, the flow area is reduced accordingly; when they are completely offset, the through-hole 15 is closed.
