Description

Technical Field

[0001] This utility model relates to the field of methanol-to-hydrogen technology, specifically to a gas-liquid separation device in a methanol-to-hydrogen equipment. Background Technology

[0002] Against the backdrop of the global push for carbon neutrality, methanol-to-hydrogen technology is of great significance. In the current process of hydrogen production using methanol, some methanol evaporates and moves out during the reaction, and then moves into the reaction vessel along with the gas produced after the reaction. During this process, it is not possible to separate the gas mixture into liquid and gas in a timely and rapid manner, which leads to a large amount of the reaction liquid being removed and wasted, thus affecting the amount of hydrogen produced.

[0003] A search revealed that patent CN220531005U discloses a gas-liquid separation device in a methanol-to-hydrogen equipment. This device utilizes the structural functions of a corrugated water-collecting plate and a refrigeration unit to circulate cooling liquid within a cooling pipe. Simultaneously, cooling gas is generated outside the cooling pipe. Combined with the rotation of a fan blade, the cooling gas accumulated on the outer wall of the cooling pipe is transported to the surface of the corrugated water-collecting plate, significantly reducing its surface temperature. This cools the gas-liquid mixture in contact with the plate, causing the vaporized liquid inside to liquefy and collect again, facilitating gas-liquid separation and preventing waste of methanol liquid during hydrogen production. Although the corrugated water-collecting plate has a good water-collecting effect, its effectiveness still needs improvement, thus limiting the gas-liquid separation efficiency. Therefore, this paper proposes a gas-liquid separation device in a methanol-to-hydrogen equipment with even better water-collecting performance, further enhancing gas-liquid separation efficiency.

[0014] Compared with the prior art, this utility model provides a gas-liquid separation device in a methanol-to-hydrogen equipment, which has the following beneficial effects:

[0015] The gas-liquid separation device in this methanol-to-hydrogen equipment facilitates gas entry from the bottom via an inlet pipe, an induced draft chamber, a cold water tank, and a conical water-collecting hood with multiple continuous V-shaped water-collecting rings. Gas passes through the cold water tank for initial water removal, and then through the conical water-collecting hood with multiple continuous V-shaped water-collecting rings, the upward-flowing air is concentrated and converged. During this convergence process, the water is further removed as completely as possible through the multiple V-shaped water-collecting rings, resulting in better water removal than using inclined corrugated water-collecting plates, thus further improving gas-liquid separation efficiency. An induction mechanism guides the gas entering the induced draft chamber upwards, and the separated gas enters a gas guide tank and is then transported to the next operating stage via a delivery pipe. A drainage mechanism facilitates the discharge of the drained water. This gas-liquid separation device in the methanol-to-hydrogen equipment exhibits superior water collection, further enhancing gas-liquid separation efficiency. Attached Figure Description

[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example:

[0026] Please see Figure 1-7 A gas-liquid separation device in a methanol-to-hydrogen equipment includes a gas-liquid separation tank 1. The interior of the gas-liquid separation tank 1 is arranged from bottom to top as follows: an induction chamber, a cold water tank 2, a conical water-collecting hood 3 with multiple continuous V-shaped water-collecting rings 4, and a heat exchange chamber. The top of the conical water-collecting hood 3 is sealed and fixedly connected through the top of the gas-liquid separation tank 1 and connected to a gas guide tank 5 with a delivery pipe. The bottom of the gas-liquid separation tank 1 is fixedly connected to an air inlet pipe 6 that communicates with the induction chamber. Multiple heat exchange pipes 7 are vertically fixedly connected through the cold water tank 2. The device also includes a drainage mechanism. An induction mechanism for inducing air upwards is provided in the induction chamber.

[0027] Specifically, the heat exchange chamber is fixedly connected to the cold water tank 2 via a connecting water pipe 16. The cold water tank 2, the connecting water pipe 16, and the heat exchange chamber are filled with heat exchange cold water. The system also includes a refrigeration mechanism connected to the heat exchange chamber and the cold water tank 2. The refrigeration mechanism includes a water pump 17 and a cooler 18 fixedly installed on the top of the gas-liquid separator 1. The input end of the water pump 17 is fixedly connected to the cold water tank 2 via a pumping pipe 19. The output end of the water pump 17 is connected to the input end of the cooler 18. The output end of the cooler 18 is fixedly connected to the top of the gas-liquid separator 1 and to the heat exchange chamber. When the water pump 17 and the cooler 18 are turned on, the heat exchange cold water in the cold water tank 2 is drawn out through the water pumping pipe 19 and sent into the cooler 18 for further cooling. Then, after passing through the heat exchange chamber, it is sent back to the cold water tank 2 through the connecting water pipe 16. It continues to exchange heat with the gas passing through the heat exchange pipes 7 through multiple heat exchange pipes 7, forming preliminary water drainage. The drained water falls into the bottom of the induced draft chamber. Due to the setting of the refrigeration mechanism, the heat exchange cold water in the heat exchange chamber exchanges heat with the conical water collection shroud 3, so that the conical water collection shroud 3 maintains a certain water drainage efficiency.

[0028] Specifically, the drainage mechanism includes a main drainage pipe 10 that is fixedly connected to a first drainage branch pipe 9 and a second drainage branch pipe 12. A drain valve 13 is installed at the bottom of the main drainage pipe 10. The first drainage branch pipe 9 is connected to the top of the cold water tank 2 on the gas-liquid separator 1, and the second drainage branch pipe 12 is connected to the bottom of the induction chamber on the gas-liquid separator 1. A connecting air pipe 11 is also fixedly connected to the main drainage pipe 10, located above the first drainage branch pipe 9 and fixedly connected to the gas-liquid separator 1. The first drainage branch pipe 9 facilitates the drainage of the induced water into the main drainage pipe 10. The connecting air pipe 11 maintains the internal air pressure balance. The second drainage branch pipe 12 facilitates the drainage of the water that has drained through the heat exchange tube 7 into the induction chamber. Then, the drain valve 13 is opened to facilitate the drainage of the drained water.

[0029] Specifically, each of the cold water tank 2 has a drain trough 8 located directly below the multiple V-shaped water collecting rings 4. Each of the multiple drain troughs 8 and the drain branch pipe 9 is connected by a connecting groove on the cold water tank 2. The multiple heat exchange pipes 7 and the multiple drain troughs 8 are arranged in a cross pattern. The multiple drain troughs 8 facilitate the collection of water drained from the V-shaped water collecting rings 4 and allow it to flow to the drain branch pipe 9 through the connecting groove. This allows the water drained from the multiple V-shaped water collecting rings 4 to be concentrated and transported to the drain branch pipe 9.

[0030] Specifically, the bottom of the gas-liquid separator 1 has a certain slope towards the drain branch pipe 2 12, which facilitates the transport of the drained water to the drain branch pipe 2 12.

[0031] Specifically, the air-inducing mechanism includes a blower blade 14 disposed in the air-inducing chamber and rotatably connected to the bottom of the gas-liquid separator 1. A drive motor 15 for driving the blower blade 14 to rotate is also fixedly installed at the bottom of the gas-liquid separator 1. Starting the drive motor 15 facilitates the rotation of the blower blade 14, thereby inducing the air entering the air-inducing chamber to rise.
