Description

Technical Field

[0001] This utility model relates to the field of droplet trap technology, and in particular to a hydrogen droplet trap. Background Technology

[0002] Currently available hydrogen droplet traps mainly fill a container with a gas-liquid mesh to capture free water in hydrogen. While their structure is simple, the droplet trapping effect is generally poor. In addition to water, the hydrogen produced by electrolyzing alkaline water also contains alkaline vapor. Therefore, the original structure is often blocked by alkali crystals in the gas-liquid mesh, resulting in a decrease in the droplet trapping effect. In severe cases, it can even completely block the hydrogen flow channel, endangering the safety of the hydrogen production system. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to propose a hydrogen droplet trap to solve the problem that the existing structure is often blocked by crystalline alkali in the gas-liquid mesh, resulting in a decrease in droplet trapping effect.

[0004] To achieve the above objectives, this utility model provides a hydrogen droplet trap, including a tank and a shaking capture mechanism. The shaking capture mechanism includes a cylinder disposed within the tank, an upper support plate disposed at the top of the cylinder, a lower support plate disposed at the bottom of the cylinder, a positioning rod passing through the upper and lower support plates, the upper and lower support plates being slidably connected to the positioning rod, a gas-liquid mesh filling the cylinder, a fixing member fixedly disposed at the top of the positioning rod, the fixing member being fixedly connected to the top of the tank, a spring sleeved on the positioning rod between the fixing member and the upper support plate, and a limiting member for limiting the lower support plate at the lower end of the positioning rod. When a large flow of hydrogen passes through the vibration capture mechanism, it pushes the cylinder upward to compress the spring. After the gas flows through, the spring pushes the cylinder downward, causing the lower support plate to collide with the limiting member. This process repeats, causing the gas-liquid mesh inside the cylinder to vibrate.

[0005] Optionally, the limiting member is a first nut threadedly connected to the lower end of the positioning rod, and a positioning pin located below the first nut and passing through the positioning rod.

[0006] Optionally, the fixing member includes a first ring member, the first ring member having a fixing ring inside for passing through the positioning rod, and a plurality of first connecting rods being distributed in a ring between the first ring member and the fixing ring, with a through hole formed between two adjacent first connecting rods.

[0007] Between the first annular component and the fixed annular component, several first connecting rods are evenly distributed in a ring shape, and a through hole is formed between two adjacent first connecting rods to reduce the weight of the fixed component and facilitate gas flow.

[0008] Optionally, the upper end of the positioning rod has a diameter abrupt change surface, the fixing member is fitted at the diameter abrupt change surface, and is fixed by a threaded connection to a second nut at the upper end of the positioning rod.

[0009] Optionally, both the upper support plate and the lower support plate include a second ring component. The second ring component has a sliding ring inside for passing through the positioning rod. A plurality of second connecting rods are distributed in a ring between the second ring component and the sliding ring, and a through hole is formed between two adjacent second connecting rods.

[0010] Optionally, the spring is a stainless steel spring.

[0011] Optionally, flanges are provided at both ends of the tank, and the fastener is welded to the upper flange. The flange is a nylon flange. The fastener is fixedly connected to the upper flange by welding, ensuring the connection strength and sealing between the fastener and the tank, making the entire hydrogen drip trap structure stable and reliable. Nylon flanges have advantages such as light weight, corrosion resistance, and good insulation, which can meet the usage requirements of hydrogen drip traps in specific working environments, while reducing the overall weight of the equipment and facilitating installation and maintenance.

[0012] The hydrogen produced by the electrolytic alkaline water hydrogen production system is not continuously released because it needs to maintain the system's own pressure. Instead, the produced hydrogen is delivered in streams. Therefore, when hydrogen carrying alkaline water vapor is delivered, the airflow exerts an upward thrust on the cylinder, pushing it upward and compressing the spring. After passing through the gas-liquid wire mesh, a large amount of free water vapor is captured by the mesh. After the airflow passes through, the compressed spring generates a downward elastic force, pushing the cylinder downward, causing the lower support plate to collide with the limiting component. This process repeats, causing the gas-liquid wire mesh inside the cylinder to vibrate continuously, which can dislodge the free water vapor from the mesh. Under the action of gravity, the free water vapor flows back into the hydrogen production system. This solves the problem of existing structures often being blocked by crystallized alkali in the gas-liquid wire mesh, thereby increasing the droplet-catching effect of the droplet trap.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] like Figure 1 and Figure 2 As shown, a hydrogen droplet trap includes a tank 1 and a shaking capture mechanism. The shaking capture mechanism includes a cylinder 2 disposed inside the tank 1, an upper support plate 3 disposed at the top of the cylinder 2, a lower support plate 4 disposed at the bottom of the cylinder 2, a positioning rod 5 passing through the upper support plate 3 and the lower support plate 4, the upper support plate 3 and the lower support plate 4 being slidably connected to the positioning rod 5, a gas-liquid mesh 6 filled inside the cylinder 2, a fixing member 7 fixedly disposed at the top of the positioning rod 5, the fixing member 7 being fixedly connected to the top of the tank 1, a spring 8 sleeved on the positioning rod 5 between the fixing member 7 and the upper support plate 3, and a limiting member for limiting the lower support plate 4 at the lower end of the positioning rod 5. When a large flow of hydrogen passes through the vibration capture mechanism, it pushes the cylinder 2 upward to compress the spring 8. After the gas flows through, the spring 8 pushes the cylinder 2 downward, causing the lower support plate 4 to collide with the limiting member. This process repeats, causing the gas-liquid mesh 6 inside the cylinder 2 to vibrate.

[0019] The hydrogen produced by the electrolytic alkaline water hydrogen production system is not continuously released because it needs to maintain the system's own pressure. Instead, the produced hydrogen is delivered in streams. Therefore, when hydrogen carrying alkaline water vapor is delivered, the airflow exerts an upward thrust on the cylinder 2, pushing it upward and compressing the spring 8. After passing through the gas-liquid mesh 6, a large amount of free water vapor is captured by the mesh. After the airflow passes through, the compressed spring 8 generates a downward elastic force, pushing the cylinder 2 downward, causing the lower support plate 4 to collide with the limiting component. This process repeats, causing the gas-liquid mesh 6 inside the cylinder 2 to vibrate continuously, which can throw the free water vapor away from the mesh 6. Under the action of gravity, the free water vapor flows back into the hydrogen production system. This solves the problem that the existing structure is often blocked by crystalline alkali in the gas-liquid mesh 6, thereby increasing the droplet-catching effect of the droplet trap.

[0020] like Figure 1 As shown, in some embodiments, the limiting member is a first nut 9 threadedly connected to the lower end of the positioning rod 5, and a positioning pin passing through the positioning rod 5 below the first nut 9. The first nut 9 and the positioning pin together constitute the limiting member, which limits the lower support plate 4, and the detachable structure facilitates subsequent maintenance.

[0021] like Figure 3 As shown, in some embodiments, the fixing member 7 includes a first ring member 10, the first ring member 10 having a fixing ring 11 for passing through the positioning rod 5, and a plurality of first connecting rods 12 being distributed in a ring between the first ring member 10 and the fixing ring 11, with a through hole formed between two adjacent first connecting rods 12.

[0022] Between the first annular member 10 and the fixed annular member 11, a plurality of first connecting rods 12 are evenly distributed in a ring. A through hole is formed between two adjacent first connecting rods 12 to reduce the weight of the fixing member 7 and facilitate gas flow.

[0023] like Figure 1 As shown, in some embodiments, the upper end of the positioning rod 5 has a diameter abrupt change surface, the fixing member 7 is fitted at the diameter abrupt change surface, and is fixed by a second nut 13 threadedly connected to the upper end of the positioning rod 5.

[0024] A second nut 13 is selected and threaded onto the upper end of the positioning rod 5. The fixing part 7 is firmly fixed to the positioning rod 5 by the second nut 13, thereby ensuring a stable connection between the fixing part 7 and the positioning rod 5. The detachable structure facilitates subsequent maintenance.

[0025] like Figure 4 As shown, in some embodiments, both the upper support plate 3 and the lower support plate 4 include a second ring member 14. The second ring member 14 is provided with a sliding ring 16 for passing through the positioning rod 5. A plurality of second connecting rods 15 are distributed in a ring between the second ring member 14 and the sliding ring 16, and a through hole is formed between two adjacent second connecting rods 15.

[0026] Between the second annular member 14 and the sliding annular member 16, several second connecting rods 15 are evenly distributed in a ring. A through hole is formed between two adjacent second connecting rods 15 to reduce the weight of the support plate and facilitate gas flow.

[0027] In some embodiments, the spring 8 is a stainless steel spring 8. The stainless steel spring 8 has good corrosion resistance and mechanical properties, enabling long-term stable use in the working environment of the hydrogen drip trap, ensuring the elasticity and service life of the spring 8, thereby ensuring the normal operation of the vibration trapping mechanism.

[0028] like Figure 1 As shown, in some embodiments, flanges 17 are provided at both ends of the tank body 1, and the fastener 7 is welded to the upper flange 17. Optionally, the flange 17 is a nylon flange 17. The fastener 7 is fixedly connected to the upper flange 17 by welding to ensure the connection strength and sealing between the fastener 7 and the tank body 1, making the entire hydrogen drip trap structure stable and reliable. The nylon flange 17 has advantages such as light weight, corrosion resistance, and good insulation, which can meet the usage requirements of the hydrogen drip trap in specific working environments, while reducing the overall weight of the equipment and facilitating installation and maintenance.
