Description

Technical Field

[0001] This utility model relates to the field of drying towers, and more particularly to a hydrogen drying tower for producing hydrogen by electrolysis of water. Background Technology

[0002] Electrolysis of water to produce hydrogen is a technology that decomposes water into hydrogen and oxygen by electrolysis. Its advantage is that it can produce hydrogen with high purity, generally above 99.9%. However, the hydrogen produced is often mixed with water, so a drying tower is needed to dry the hydrogen.

[0003] During drying, a drying plate is typically installed inside a drying tower to remove moisture from the hydrogen by guiding it through the drying plate. However, as the hydrogen moves inside the drying tower, it comes into contact with the inner wall, causing some of the moisture to condense. This condensation then mixes with the dried hydrogen, leading to water contamination within the dried hydrogen. This results in additional consumption of the drying plate and a reduced lifespan. Therefore, a hydrogen drying tower for water electrolysis to produce hydrogen is proposed to address these issues. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a hydrogen drying tower for hydrogen production by water electrolysis, which aims to improve the problem in the prior art that "when the dried hydrogen moves inside the tower, it carries away the condensate attached to the inner wall of the tower, which leads to additional consumption of the drying plate".

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydrogen drying tower for producing hydrogen by electrolysis of water, comprising a tank, an exhaust port provided on the upper surface of the tank, an air inlet pipe provided on the outer wall of the tank, a drain pipe provided on the lower surface of the tank, a drying plate installed on the inner wall of the tank, a cleaning assembly provided on the inner wall of the tank, and a diversion assembly provided on the upper surface of the air inlet pipe;

[0011] As a further description of the above technical solution:

[0012] A connecting rod is fixedly connected to the lower surface of the transmission rod, and a receiving sleeve is fixedly connected to the upper surface of the diverter. The connecting rod passes through and is rotatably connected to the inner wall of the receiving sleeve.

[0013] As a further description of the above technical solution:

[0014] The connecting rod and the impeller are connected by a gear set, which is located on the inner wall of the receiving sleeve.

[0015] As a further description of the above technical solution:

[0031] 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.

[0032] Reference Figures 1-3This utility model provides an embodiment of a hydrogen drying tower for producing hydrogen through water electrolysis, comprising a tank 1 for containing hydrogen, an exhaust port 3 for discharging dried hydrogen on the upper surface of the tank 1, an inlet pipe 2 for allowing hydrogen to enter the tank 1 on the outer wall of the tank 1, a drain pipe 4 for discharging condensate on the lower surface of the tank 1, a drying plate 8 for drying hydrogen installed on the inner wall of the tank 1, the drying plate 8 absorbing moisture from the hydrogen as it passes through the drying plate 8, a cleaning component 5 for cleaning the inner wall of the tank 1, and a diversion component 7 for guiding the dispersed flow of hydrogen on the upper surface of the inlet pipe 2.

[0033] Reference Figures 1-3 The cleaning component 5 includes a drive motor 51 for providing power. The drive motor 51 is mounted on the upper surface of the tank 1. The drive motor 51 is a low-speed motor with a low output shaft speed. A rotating shaft 52 for outputting power is fixedly connected to the lower surface of the output shaft of the drive motor 51. A transmission rod 53 for transmitting power is fixedly connected to the bottom end of the rotating shaft 52. Baffles 55 for blocking condensate splashing are fixedly connected to both the front and rear ends of the transmission rod 53. A scraper 54 for guiding the flow of condensate is fixedly connected to the upper surface of the baffle 55. When the transmission rod 53 rotates, it will drive the baffle 55 to rotate, which will drive the scraper 54 to rotate. The rotation of the scraper 54 can guide the condensate to flow downward. The scraper 54 is inclined and fits against the inner wall of the tank 1.

[0034] Reference Figures 2-4 The cleaning assembly 5 also includes a guide plate 56 for guiding the condensate downwards. The guide plate 56 is fixedly connected to the lower surface of the scraper 54 near the bottom. When the scraper 54 rotates, it guides the condensate downwards until the condensate is separated from the guide plate 56. Then, the scraper 54 continues to rotate, which drives the guide plate 56 to guide the condensate downwards. The diversion assembly 7 includes a diversion pipe 72 for guiding the flow of hydrogen. The diversion pipe 72 is fixedly connected to the upper surface of the inlet pipe 2. The hydrogen discharged from the inside of the diversion pipe 72 will directly enter the inside of the diversion pipe 72. An impeller 7 for guiding the dispersion of hydrogen is rotatably connected to the inner wall of the diversion pipe 72. 6. The outer wall of the diversion pipe 72 is provided with an exhaust port 73 for discharging hydrogen gas. The lower surface of the transmission rod 53 is fixedly connected with a connecting rod 71 for transmitting power. The upper surface of the diversion pipe 72 is fixedly connected with a receiving sleeve 75 for accommodating the acceleration gear set 74. The connecting rod 71 passes through and is rotatably connected to the inner wall of the receiving sleeve 75. When the transmission rod 53 rotates, it will drive the connecting rod 71 to rotate synchronously. The connecting rod 71 and the impeller 76 are connected by transmission through the acceleration gear set 74. When the connecting rod 71 rotates, it will drive the impeller 76 to rotate through the acceleration gear set 74. The acceleration gear set 74 is located on the inner wall of the receiving sleeve 75.

[0035] Reference Figures 3-5The acceleration gear set 74 includes a drive wheel 741 for outputting power. The drive wheel 741 is fixedly connected to the bottom end of the connecting rod 71. When the connecting rod 71 rotates, it drives the drive wheel 741 to rotate. A transmission wheel 742 for transmitting power is rotatably connected to the inner wall of the receiving sleeve 75. The transmission wheel 742 meshes with the drive wheel 741. When the drive wheel 741 rotates, it drives the transmission wheel 742 to rotate. A transmission wheel 743 is fixedly connected to the lower surface of the transmission wheel 742. When the transmission wheel 742 rotates, it drives the transmission wheel 743 to rotate. The impeller 76 rotates, and a driven wheel 744 is fixedly connected to the upper surface of the impeller 76 to drive the impeller 76 to rotate. The transmission wheel 743 meshes with the driven wheel 744. When the transmission wheel 743 rotates, it will drive the driven wheel 744 to rotate. The motion is transmitted through the transmission wheel 742 and the transmission wheel 743, which can accelerate the rotation of the impeller 76. The air inlet pipe 2 is set in an L shape and the upper surface of the air inlet pipe 2 is higher than the upper surface of the guide plate 56. This setting can further reduce the probability of hydrogen contacting condensate. The lower surface of the tank body 1 is fixedly connected with a support foot 6.

[0036] Working Principle: Hydrogen gas enters the drying tower through the L-shaped inlet pipe 2. The diversion assembly 7 on the upper surface of the inlet pipe 2 begins to function. After the hydrogen gas enters the diversion pipe 72, the drive motor 51 drives the transmission rod 53 to rotate. The transmission rod 53 drives the acceleration gear set 74 to rotate through the connecting rod 71. The driving wheel 741 of the acceleration gear set 74 rotates with the connecting rod 71, driving the meshing transmission wheel 742 to rotate. The transmission wheel 742 then drives the transmission wheel 743 to rotate, and finally the transmission wheel 743 drives the driven wheel 744, causing the impeller 76 to rotate at high speed. Under the action of the impeller 76, the hydrogen gas is discharged from the exhaust port 73 on the outer wall of the diversion pipe 72 to all directions, avoiding hydrogen gas from a single location, increasing the contact area between the hydrogen gas and the drying plate 8, improving the utilization rate of the drying plate 8. The dispersed hydrogen gas passes through the drying plate 8, and the drying plate 8 absorbs the moisture in the hydrogen gas, realizing the drying treatment of the hydrogen gas. The dried hydrogen gas is discharged from the exhaust port 3 on the upper surface of the tank 1.

[0037] During the drying process, condensate formed when hydrogen comes into contact with the inner wall of tank 1 adheres to the inner wall. At this time, drive motor 51 starts, rotating shaft 52. Shaft 52 drives transmission rod 53 to rotate, causing baffles 55 and scrapers 54 at both ends of transmission rod 53 to rotate accordingly. Scrapers 54 are inclined and conform to the inner wall of tank 1, guiding the condensate downwards during rotation. A guide plate 56 near the bottom of the lower surface of scraper 54 further guides the condensate, accelerating its downward flow. Finally, the condensate is discharged through drain pipe 4 on the lower surface of tank 1, reducing the probability of contact between the dried hydrogen and condensate, minimizing the additional consumption of drying plate 8 due to contact with condensate, and improving the service life of drying plate 8.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
