Description

Technical Field

[0001] This utility model relates to the technical field of gas-liquid distributors, specifically a slotted structure for a gas-liquid distributor. Background Technology

[0002] Tower equipment is one of the most important pieces of equipment in chemical, petrochemical, and oil refining production. Based on their internal structure, towers are broadly classified into plate towers and packed towers. In packed towers, while the high performance of the packing itself is crucial, the matching internals, especially the liquid and gas distributors, are equally vital. The more efficient the packing, the more demanding the gas-liquid distribution device becomes.

[0003] Existing gas-liquid distributors mainly consist of a frustum with drainage holes, a gas riser, and a V-shaped baffle plate. However, in actual use, the V-shaped baffle plate tends to accumulate a large amount of liquid at its bottom, which can prevent the liquid at the top of the column from flowing smoothly downwards. This results in the product at the top of the column always carrying liquid, reducing the separation efficiency of the packed column. At the same time, the water flowing down from the top of the column in existing gas-liquid distributors continuously drips onto the baffle plate, and the overflowing liquid falls from both ends of the baffle plate. It is necessary to shut off the water flow from the top of the column to control the liquid content in the gas-liquid distributor, which cannot achieve automatic quantitative control and is inconvenient to use. Therefore, those skilled in the art have proposed a tray-type structure for gas-liquid distributors to solve the problems mentioned in the background. Utility Model Content

[0004] The purpose of this invention is to provide a slotted structure for a gas-liquid distributor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A tray-type structure for a gas-liquid distributor includes a base plate with a plurality of gas-lifting slots evenly spaced on the base plate. The length of each gas-lifting slot is related to its position on the base plate, with the end of each slot near the edge of the base plate. An elastic support assembly is provided at the top of the inner cavity of each gas-lifting slot, and a drain assembly is installed at the top of each gas-lifting slot. The top of the elastic support assembly is connected to the bottom of a baffle plate. A plurality of vertical guide tubes are evenly distributed at the bottom of the baffle plate, with the top of each vertical guide tube connected to the top of the baffle plate and the bottom of each vertical guide tube interlocking with the drain assembly. The upper part of the elastic support assembly interlocks with the middle part of the drain assembly. When the liquid volume on the baffle plate reaches a certain level, the drain assembly can drain the liquid in the vertical guide tubes to the base plate.

[0007] As a further embodiment of this utility model: the elastic support assembly includes a vertical rod and an annular support plate. The outer wall of the annular support plate is connected to the top inner wall of the air riser via a connecting rod. The bottom of the vertical rod is interlocked with the middle of the annular support plate. The top of the vertical rod is connected to the bottom of the baffle plate. A fixing plate is connected to the middle of the vertical rod. An elastic element is sleeved on the lower part of the vertical rod. The bottom of the elastic element is connected to the top of the annular support plate. The top of the elastic element is connected to the bottom of the fixing plate. The upper part of the vertical rod is interlocked with the drainage assembly.

[0008] As a further improvement of this utility model: two elastic support components are symmetrically connected to the bottom end of the baffle plate, and the two elastic support components are respectively set at both ends of the inner cavity of the air riser.

[0009] As a further embodiment of this utility model: the drainage assembly includes a plate and a drainage pipe. A first vertical hole is provided in the middle of the plate. The upper part of the vertical rod is inserted and fitted into the first vertical hole. A second vertical hole is provided on the side of the plate. The top end of the drainage pipe is connected to the side of the second vertical hole. The bottom end of the drainage pipe faces the bottom plate.

[0010] As a further improvement of this utility model: a mounting bracket is installed on the lower outer wall of the plate, and the bottom end of the mounting bracket is detachably installed on the top of the air riser.

[0011] As a further embodiment of this utility model: the lower part of the vertical guide tube is inserted and fitted into the second vertical hole, the outer wall of the vertical guide tube is slidably fitted with the inner wall of the second vertical hole, the bottom end of the vertical guide tube is closed, and the bottom side wall of the vertical guide tube is provided with a side drain hole that cooperates with the drain pipe.

[0012] This invention has the following advantages: The structure uses a baffle plate to block the falling liquid. When the liquid volume reaches a certain level, the baffle plate moves downward, and the elastic support component is compressed. At this time, the liquid in the vertical guide tube can be discharged to the bottom plate through the drainage component. Subsequently, the baffle plate is reset under the action of the elastic support component. The movable baffle plate achieves the diversion of the liquid, and the elastic force of the elastic support component ensures that the dripping liquid is constant and controllable, thus having greater practicality.

A plurality of air-lifting slots 2 are evenly spaced on the base plate 1. The length of each air-lifting slot 2 is related to its position on the base plate 1. The ends of the air-lifting slots 2 are close to the edge of the base plate 1. An elastic support assembly 4 is provided at the top of the inner cavity of each air-lifting slot 2. A drain assembly 5 is installed at the top of each air-lifting slot 2. The top of the elastic support assembly 4 is connected to the bottom of a baffle plate 3. A plurality of vertical guide tubes 301 are evenly distributed at the bottom of the baffle plate 3. The tops of the vertical guide tubes 301 are connected to the top of the baffle plate 3, and the bottoms of the vertical guide tubes 301 are interlocked with the drain assembly 5. The upper part of the elastic support assembly 4 is interlocked with the middle part of the drain assembly 5. When the liquid volume on the baffle plate 3 reaches a certain level, the drain assembly 5 can drain the liquid in the vertical guide tubes 301 onto the base plate 1.

[0020] Please see Figures 1 to 4The elastic support assembly 4 includes a vertical rod 401 and an annular support plate 404. The outer wall of the annular support plate 404 is connected to the top inner wall of the air riser 2 via a connecting rod 405. The bottom of the vertical rod 401 is interlocked with the middle of the annular support plate 404. The top of the vertical rod 401 is connected to the bottom of the baffle plate 3. A fixing plate 402 is connected to the middle of the vertical rod 401. An elastic element 403 is sleeved on the lower part of the vertical rod 401. The bottom of the elastic element 403 is connected to the top of the annular support plate 404. The top of the elastic element 403 is connected to the bottom of the fixing plate 402. The upper part of the vertical rod 401 is interlocked with the drain assembly 5. Two elastic support assemblies 4 are symmetrically distributed at the bottom of the baffle plate 3. The two elastic support assemblies 4 are respectively set at both ends of the inner cavity of the air riser 2 to ensure the stability of the baffle plate 3.

[0021] Example 2: See Figures 1 to 3 Based on Embodiment 1, the drainage assembly 5 includes a plate 501 and a drainage pipe 504. A first vertical hole 502 is provided in the middle of the plate 501, and the upper part of the vertical rod 401 is inserted and fitted into the first vertical hole 502. A second vertical hole 505 is provided on the side of the plate 501. The top end of the drainage pipe 504 is connected to the side of the second vertical hole 505. The bottom end of the drainage pipe 504 faces the bottom plate 1. A mounting bracket 503 is installed on the lower outer wall of the plate 501. The bottom end of the mounting bracket 503 is detachably installed on the top of the air riser 2. In this embodiment, the drainage pipe 504 is right-angled.

[0022] Please see Figures 1 to 3 The lower part of the vertical conduit 301 is inserted and fitted inside the second vertical hole 505. The outer wall of the vertical conduit 301 slides and fits against the inner wall of the second vertical hole 505. The bottom end of the vertical conduit 301 is closed. The bottom side wall of the vertical conduit 301 is provided with a side drain hole 302 that cooperates with the drain pipe 504.

[0023] Working principle: During use, the liquid is supported by the top of the baffle plate 3. Initially, the side drain hole 302 at the bottom of the vertical guide tube 301 is located above the drain pipe 504. At this time, the side drain hole 302 is blocked by the inner wall of the second vertical hole 505. As the liquid accumulation volume on the baffle plate 3 increases, the baffle plate 3 drives the vertical rod 401 to move down. The vertical rod 401 drives the fixed plate 402 to squeeze the elastic element 403. The baffle plate 3 simultaneously drives the vertical guide tube 301 to move down. When the liquid volume on the baffle plate 3 reaches a certain level, the side drain hole 302 moves to a position flush with the top end of the drain pipe 504. At this time, the liquid on the baffle plate 3 can be drained into the drain pipe 504 through the vertical guide tube 301. Ideally, it drips down through the bottom end of the drain pipe 504, thus diverting the liquid on the baffle plate 3.
