Description

Technical Field

[0001] This utility model relates to the field of hydrogen scrubbing tower technology, and in particular to a gas-liquid distributor inside the tower. Background Technology

[0002] A hydrogen scrubbing tower is a device used to process wet hydrogen. Its main function is to remove impurities and moisture from the wet hydrogen by cooling, washing, and purifying it. Wet hydrogen typically originates from the electrolysis of water to produce hydrogen and contains a large amount of water vapor and impurities (such as alkaline mist). The hydrogen scrubbing tower washes the hydrogen by spraying cooling water, lowering its temperature and removing impurities, thus achieving a higher purity for subsequent use or transportation.

[0003] In existing technologies, the gas-liquid distributor in a hydrogen scrubbing tower is a key component, and its performance directly affects the cooling and scrubbing effect of hydrogen. However, the gas nozzles and atomizing nozzles of existing fixed distributors are in fixed positions, making it difficult to achieve sufficient gas-liquid turbulent contact, resulting in low mixing efficiency of hydrogen and cooling water and unsatisfactory scrubbing effect. Therefore, we propose an in-tower gas-liquid distributor to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a gas-liquid distributor for use in towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A gas-liquid distributor for use in a tower includes a scrubbing tower. An inner cylinder is fixedly connected inside the scrubbing tower, and a protective frame is fixedly connected to the top of the scrubbing tower. Through holes are provided on the outer walls of both the scrubbing tower and the inner cylinder. A rotating tube is rotatably connected to the inner wall of each through hole. A rotary joint is fixedly connected to the top of the rotating tube. A motor is fixedly connected inside the protective frame. Gears are fixedly fitted onto both the motor's output shaft and the outer wall of the rotating tube, and the two gears are meshed together. A rectangular tube is fixedly fitted onto the outer wall of the rotating tube. Multiple gas nozzles are uniformly fixedly connected to the bottom of the rectangular tube. An air inlet assembly is provided on the outer wall of the rectangular tube, and a liquid outlet assembly is provided at the bottom of the rotating tube.

[0007] Preferably, the air intake assembly includes a hollow ring, the outer wall of the rectangular tube is fixedly connected to the inner wall of the ring, a docking ring is rotatably fitted on the outer wall of the ring, the outer wall of the docking ring is fixedly connected to the inner wall of the inner cylinder, and through holes are opened on the outer walls of both the washing tower and the inner cylinder. An air intake pipe is fixedly connected to the inner wall of the through hole, and one end of the air intake pipe is fixedly connected to the outer wall of the docking ring. Hydrogen gas is allowed to enter the interior of the inner cylinder by setting the air intake assembly.

[0008] Preferably, the liquid outlet assembly includes a liquid outlet pipe, the bottom of the rotating pipe is fixedly connected to the outer wall of the liquid outlet pipe, and multiple atomizing nozzles are uniformly fixedly connected to the top of the liquid outlet pipe. A mesh frame is fixedly connected inside the inner cylinder, and packing is placed inside the mesh frame. By setting the liquid outlet assembly, cooling water enters the interior of the inner cylinder.

[0009] Preferably, a cooling pipe is fixedly connected to the top of the rotary joint, one end of which penetrates the outer wall of the protective frame and is fixedly connected to a water pump, so that external cooling water is pumped into the cooling pipe by the water pump.

[0010] Preferably, a bearing seat is fixedly fitted on the outer wall of the rotating tube, and the outer ring of the bearing seat is fixedly connected to the top of the washing tower. The rotating tube is stabilized by setting the bearing seat.

[0011] Preferably, the outer wall of the washing tower is fixedly connected to a drain pipe and an air outlet pipe, and electronic valves are fixedly installed on the outer walls of both the drain pipe and the air outlet pipe, and the opening and closing of the drain pipe and the air outlet pipe are controlled by setting electronic valves.

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This design utilizes a motor to drive the rotating tube, rectangular tube, and liquid outlet tube to rotate synchronously, creating a dynamic distribution between the gas nozzles and atomizing nozzles during movement. This overcomes the limitations of fixed distributors and enhances turbulent gas-liquid contact. Hydrogen is injected from top to bottom, while cooling water is atomized and sprayed from bottom to top, forming a counter-flow. Combined with the rotational motion, this further extends the contact time and improves mass transfer efficiency. Furthermore, the packing material provides secondary cooling and washing, fully utilizing gravity settling to achieve deep purification. Attached Figure Description

One end of the cooling pipe penetrates the outer wall of the protective frame 3 and is fixedly connected to a water pump. The water pump draws cooling water through the cooling pipe into the rotary joint 5 and then delivers it downwards into the rotating pipe 4.

[0023] A motor 6 is fixedly connected inside the protective frame 3. Gears 7 are fixedly fitted on both the output shaft of the motor 6 and the outer wall of the rotating tube 4. The two gears 7 are meshed together. The operation of the motor 6 drives the rotating tube 4 to rotate through the two gears 7. A rectangular tube 8 is fixedly fitted on the outer wall of the rotating tube 4. Multiple gas nozzles 9 are evenly fixedly connected to the bottom of the rectangular tube 8. The hydrogen gas to be washed is sprayed downward through the multiple gas nozzles 9. A drain pipe 16 and an outlet pipe 17 are fixedly connected to the outer wall of the washing tower 1. Electronic valves 18 are fixedly installed on the outer walls of both the drain pipe 16 and the outlet pipe 17. One end of the outlet pipe 17 can be fixedly connected to an existing gas-liquid separator. The specific model adopts the existing conventional model.

[0024] The outer wall of the rectangular tube 8 is provided with an air intake assembly, which includes a hollow ring 10. The outer wall of the rectangular tube 8 is fixedly connected to the inner wall of the ring 10. A docking ring 11 is rotatably fitted on the outer wall of the ring 10. The docking ring 11 assists the ring 10 in stable rotation without affecting the hydrogen intake. The outer wall of the docking ring 11 is fixedly connected to the inner wall of the inner cylinder 2. Both the outer walls of the washing tower 1 and the inner cylinder 2 are provided with through holes. An air intake pipe 12 is fixedly connected to the inner wall of the through hole. One end of the air intake pipe 12 is fixedly connected to the outer wall of the docking ring 11. The other end of the air intake pipe 12 is fixedly connected to an existing air pump, which draws the hydrogen to be washed.

[0025] The bottom of the rotating tube 4 is provided with a liquid outlet assembly, which includes a liquid outlet pipe 13.

The mesh frame is filled with filler 15. The mesh frame is made of stainless steel wire mesh.

[0026] Working principle: During use, the hydrogen gas to be washed is pumped into the inlet pipe 12 by the existing air pump, and then enters the interior of the docking ring 11 through the inlet pipe 12. The hydrogen gas to be washed enters the circular ring 10 and the rectangular tube 8 through the docking ring 11, and is then sprayed downwards by multiple gas nozzles 9. Meanwhile, the water pump pumps cooling water through the cooling pipe to the rotary joint 5, and then delivers it downwards to the rotating tube 4. From the rotating tube 4, it enters the liquid outlet pipe 13, and finally sprays upwards from multiple atomizing nozzles 14, forming a gas-liquid countercurrent effect. The motor 6 drives the connected gear 7 to rotate, which in turn drives another gear 7 to rotate, thereby rotating the rotating tube 4. The rotation of the rotating tube 4 causes the rectangular tube 8 and the liquid outlet pipe 13 to rotate, so as to facilitate gas-liquid mixing and facilitate the cooling and washing of the hydrogen gas. Finally, the hydrogen gas and cooling water flow downwards to the packing 15 under their own gravity. After secondary cooling and washing, the washed hydrogen gas is discharged from the outlet pipe 17.
