Description

Technical Field

[0001] This utility model relates to the field of dryer technology, and in particular to an internal drying type hydrogen dryer. Background Technology

[0002] Alkaline water electrolysis hydrogen production equipment generates hydrogen and oxygen. The gas contains a lot of moisture. The semiconductor industry or chemical industry generally requires hydrogen with a purity of 99.999% and a dew point of -60℃. Therefore, a matching hydrogen purification device is required. The hydrogen purification device is equipped with a dryer, which has an inner and outer cylinder structure. The jacket is filled with molecular sieves to adsorb the moisture in the hydrogen and make its dew point reach -60℃.

[0003] Traditional dryers typically have a hydrogen inlet in the inner cylinder and a hydrogen outlet in the outer cylinder. However, with the increasing scale of projects, this structure has become somewhat inadequate. Having only one inlet and outlet leads to the formation of inherent channels within the sandwiched molecular sieves after prolonged operation. This results in uneven utilization of the molecular sieves, shorter lifespans in some areas, and limited moisture adsorption in others, leading to unacceptable dew point readings. Utility Model Content

[0004] The purpose of this utility model is to provide an internal drying hydrogen dryer in order to solve the above-mentioned problems.

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

The uniform exhaust assembly includes a rotating rod, a fan wheel, a baffle, a bevel gear, a bevel gear, a rotating rod, a belt, a rotating drum, and a diverter pipe. The rotating rod is rotatably connected to the inner wall of the inner cylinder, and the rotating rod extends from the inner cylinder... The inner cylinder extends outward from the interior. One end of the rotating rod is fixedly connected to a wind turbine inside the inner cylinder. A baffle is provided on the top of the wind turbine and is fixedly connected to the inner wall of the inner cylinder. One end of the rotating rod is fixedly connected to a bevel gear. A bevel gear is meshed with the outer wall of the bevel gear. The inner wall of the bevel gear is fixedly connected to the rotating rod. The outer wall of the rotating rod is connected to a belt through a pulley. The bottom of the inner cylinder is rotatably connected to a rotating drum. The belt is connected to the rotating drum through a pulley. A diversion pipe is provided on the outer wall of the rotating drum.

[0007] Preferably, the number of the diversion pipes is set to four, and the four diversion pipes are arranged in a ring at equal intervals around the rotating drum.

[0008] Preferably, a slider is fixedly connected to the top of the rotating cylinder, and a groove adapted to the slider is opened at the bottom of the inner cylinder, and the cross-section of the slider is T-shaped.

[0009] Preferably, a sealing box is fixedly connected to the inner wall of the outer cylinder, and both the first bevel gear and the second bevel gear are located inside the sealing box.

[0010] Preferably, a heater is installed on the inner wall of the inner cylinder.

[0011] Preferably, a support frame is fixedly connected to the outer wall of the outer cylinder, and a caster wheel is installed at the bottom of the support frame.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] In this application, after hydrogen gas is discharged into the inner cylinder, it impacts the wind turbine, causing it to rotate. The wind turbine then drives the first rotating rod, which in turn rotates the first bevel gear. The first bevel gear meshes with the second bevel gear, causing the second rotating rod to rotate. The second rotating rod then drives the rotating drum to rotate via a belt. As the drum rotates, centrifugal force forces the hydrogen gas out through the diversion pipe. In this way, the hydrogen gas is discharged evenly from the inner cylinder in a circular pattern and enters the molecular sieve, thereby enabling the molecular sieve to be used uniformly and improving its overall utilization rate.

The wind turbine 9 drives the wind turbine wheel 9 to rotate. The top of the wind turbine wheel 9 is equipped with a baffle 10, which is half the cross-section of the inner cylinder 2, so that the wind turbine wheel 9 can rotate stably. The baffle 10 is fixedly connected to the inner wall of the inner cylinder 2. One end of the rotating rod 8 located inside the outer cylinder 1 is fixedly connected to a bevel gear 11 for meshing with a bevel gear 12. The outer wall of the bevel gear 11 meshes with a bevel gear 12 for driving the rotating rod 13 to rotate. The inner wall of the bevel gear 12 is fixedly connected to a rotating rod 13 for driving the belt 14 to rotate. The outer wall of the rotating rod 13 is connected to the belt 14 through a pulley. The belt 14 will drive the rotating drum 15 to rotate. The bottom of the inner cylinder 2 is rotatably connected to the rotating drum 15 for driving the diversion pipe 16 to rotate. The belt 14 is connected to the rotating drum 15 through a pulley. The outer wall of the rotating drum 15 is connected to a diversion pipe 16 for uniformly discharging hydrogen.

[0024] like Figure 2 As shown, four diversion pipes 16 are arranged in a ring around the rotating cylinder 15 at equal intervals. These four diversion pipes allow for more even hydrogen discharge. A slider 17 is fixedly connected to the top of the rotating cylinder 15, and a groove adapted to the slider 17 is provided at the bottom of the inner cylinder 2. The slider 17 has a T-shaped cross-section. Figure 4 As shown, a sealing box 18 is fixedly connected to the inner wall of the outer cylinder 1. The sealing box 18 can prevent moisture inside the dryer from contaminating the bevel gear 11 and bevel gear 212, causing them to rust. Both bevel gear 11 and bevel gear 212 are located inside the sealing box 18. A heater 19 for improving drying efficiency is installed on the inner wall of the inner cylinder 2. A support frame 20 is fixedly connected to the outer wall of the outer cylinder 1. A caster wheel 21 for moving the dryer is installed at the bottom of the support frame 20.

[0025] Working Principle: In this embodiment, the internal drying type hydrogen dryer is used by the operator first discharging hydrogen into the inner cylinder 2 through the inlet pipe 4. After passing through the baffle 10, the hydrogen impacts the fan wheel 9, which drives the rotating rod 8 to rotate. The rotating rod 8 then drives the bevel gear 11 to rotate, which meshes with the bevel gear 12. The bevel gear 12 then drives the rotating rod 13 to rotate, which in turn drives the rotating drum 15 to rotate via the belt 14. During the rotation, the rotating drum 15 uses centrifugal force to evenly discharge hydrogen through the four diversion pipes 16. In this way, the hydrogen is evenly discharged into the interlayer between the outer cylinder 1 and the inner cylinder 2 and comes into contact with the molecular sieve 7, thereby enabling the molecular sieve 7 to be used evenly and improving its overall utilization rate.

[0026] In summary, after hydrogen gas is discharged into the inner cylinder 2, it impacts the wind turbine 9, causing it to rotate. The wind turbine 9 then drives the rotating rod 8, causing the bevel gear 11 to rotate. The bevel gear 11 meshes with the bevel gear 12, causing the rotating rod 13 to rotate. The rotating rod 13 then drives the rotating drum 15 to rotate via the belt 14. When the rotating drum 15 rotates, it uses centrifugal force to discharge hydrogen gas through the diversion pipe 16. In this way, the hydrogen gas is discharged evenly from the inner cylinder 2 in a circular pattern and enters the molecular sieve 7, thereby enabling the molecular sieve 7 to be used uniformly and improving its overall utilization rate.
