Description

Technical Field

[0001] This utility model relates to the field of gas analysis instrument technology, specifically to a water removal device for a hydrogen oxygen analyzer. Background Technology

[0002] During the analysis of oxygen in hydrogen, trace amounts of moisture in the hydrogen can interfere with the sensor response of the analytical instrument, leading to a decrease in analytical accuracy and even affecting the service life of the equipment. Therefore, deep dehydration of hydrogen is a key step to ensure analytical accuracy.

[0003] Existing hydrogen oxygen analyzers mostly use a single drying component for water adsorption. When the drying component becomes saturated, it needs to be shut down for replacement or regeneration, resulting in excessively long interruptions in the analysis process and seriously affecting work efficiency. At the same time, if the accumulated liquid generated during the water removal process is not treated in time, it can easily cause the risk of hydrogen leakage. Existing devices mostly rely on manual monitoring of drainage, which has a low degree of automation and makes it difficult to achieve accurate and safe management of accumulated liquid.

[0004] Therefore, we propose a water removal device for a hydrogen oxygen analyzer to solve the problems mentioned above. Utility Model Content

[0005] 1. The technical problem to be solved by the utility model:

[0006] The purpose of this invention is to provide a water removal device for a hydrogen oxygen analyzer, so as to solve the problems currently found in the market as described in the background art.

[0007] 2. Technical Solution:

[0008] To achieve the above objectives, this utility model provides the following technical solution: a water removal device for a hydrogen oxygen analyzer, comprising a housing, an air inlet pipe connected to the upper side of the housing, an air outlet pipe connected to the upper right side of the housing, a placement opening on the upper left side of the housing, a drain pipe connected to the lower end of the housing, and a solenoid valve installed in the middle of the drain pipe.

[0009] Inside the housing, a control rod is mounted via a bearing, and a frame is fitted around the outer side of the middle part of the control rod. Two sieve cylinders are detachably installed inside the frame. An adjusting component is installed at the upper end of the housing, and a pressing component is installed at the output end of the adjusting component. The pressing component drives the two sieve cylinders inside the frame to correspond to the air outlet and the placement port, respectively.

[0010] Furthermore, a water level sensor is installed inside the housing. The water level sensor is connected to a solenoid valve via a microcontroller. The microcontroller receives the water level sensor signal and controls the solenoid valve to open and close. Additionally, a moisture sieve for adsorbing trace amounts of moisture in hydrogen is installed inside the sieve cylinder.

[0011] The above technical solution enables the microcontroller to trigger the solenoid valve to open when the water level reaches the set threshold, allowing the accumulated water to be discharged through the drain pipe. Once the water level drops to a safe value, the solenoid valve automatically closes to prevent hydrogen leakage and achieve automated water management.

[0012] Furthermore, drive bars are evenly distributed on the outer side of the middle part of the control rod, and a limit plate is provided at the lower part of the drive bar. The limit plate is fixedly sleeved on the outer side of the lower end of the control rod, and the frame is slidably disposed on the outer side of the drive bar. At the same time, the limit plate is used to limit the lowest position of the frame.

[0013] The above technical solution enables the frame to rotate by the drive bar after the control lever is rotated, and the frame can slide up and down on the outside of the control lever.

[0014] Furthermore, the adjusting member includes a guide rod fixed inside the housing, and the adjusting member also includes a threaded rod mounted inside the housing via a bearing.

[0015] The above technical solution enables the top pressure component to move up and down when the drive threaded rod rotates.

[0016] Furthermore, the top pressing component includes a support plate located below the frame. Sleeves are fixed at both the front and rear ends of the support plate, and a through hole is opened on the right side of the support plate. A sealing plate is fixed on the left side of the support plate, and a sealing ring one is fixed on the outer side of the through hole and the upper end of the sealing plate. A sealing ring two is fixed on the upper end of the two sleeves.

[0017] The above technical solution enables the top pressure component to move up and down synchronously when it is subjected to force, while gas can enter the screen cylinder inside the frame through the through hole for water removal.

[0018] Furthermore, the sleeve on the front side is threadedly connected to the threaded rod, while the sleeve on the rear side is slidingly connected to the guide rod.

[0019] The above technical solution enables the top pressure component to move up and down.

[0020] Furthermore, two sealing rings are installed on the upper inner wall of the housing, which fit tightly against the sealing rings when the frame moves upward.

[0021] The above technical solutions can improve the sealing effect.

[0022] 3. Beneficial effects:

[0023] Compared with the prior art, the water removal device of the hydrogen oxygen analyzer of this utility model, when the water in the right sieve cylinder is saturated, drives the frame to rotate and switch the position of the sieve cylinder through the cooperation of the adjusting component, the top pressure component and the control rod, and then moves the top pressure component upward to seal. At the same time, the old sieve cylinder can be taken out for drying and regeneration, shortening the downtime. The specific details are as follows:

[0024] Moist hydrogen enters the housing through the inlet pipe and then enters the sieve cylinder through the through hole. The moisture sieve in the sieve cylinder adsorbs the trace amounts of residual water vapor in the gas through its porous structure or chemical affinity, achieving deep drying. Finally, the dried hydrogen after being treated by the moisture sieve is discharged through the outlet pipe so that it can be subsequently entered into the analyzer. Meanwhile, the water level sensor at the bottom of the housing monitors the water level in real time. When the water level reaches the set threshold, the microcontroller triggers the solenoid valve to open, and the water is discharged through the drain pipe. After the water level drops to a safe value, the solenoid valve automatically closes to prevent hydrogen leakage and achieve automated water management.

[0025] When the moisture in the right-side screen cylinder is saturated, the adjusting component drives the top pressure component to move downward. After the top pressure component is removed, the frame moves away from the sealing ring three under the action of gravity. The frame then fits against the limiting plate, and the top pressure component continues to move downward until the frame moves away from the sealing ring one. Then, the control rod is driven to rotate, and the control rod drives the frame to rotate through the drive bar, causing the screen cylinder that was originally located on the right side after regeneration to rotate below the air outlet pipe. The screen cylinder that was originally located on the right side rotates to the placement port. Then, the threaded rod is driven to rotate, causing the top pressure component to move upward, so that the upper and lower ends of the frame fit tightly against the sealing ring three and the sealing ring one respectively. At the same time, the sleeve fits tightly against the sealing ring two, improving the sealing performance. Then, the screen cylinder that was originally located on the right side can be taken out from the placement port for drying and regeneration, shortening the downtime. Attached Figure Description

[0036] Please see Figure 1-5A dehydration device for a hydrogen oxygen analyzer includes a housing 1. An air inlet pipe 2 is connected to the upper side of the housing 1, and an air outlet pipe 3 is connected to the upper right side of the housing 1. A placement port 11 is opened on the upper left side of the housing 1. A drain pipe 4 is connected to the lower end of the housing 1, and a solenoid valve 5 is installed in the middle of the drain pipe 4. A water level sensor 51 is installed inside the housing 1. The water level sensor 51 is connected to the solenoid valve 5 through a microcontroller. The microcontroller receives the signal from the water level sensor 51 and controls the opening and closing of the solenoid valve 5. A moisture sieve for adsorbing trace amounts of moisture in hydrogen is installed inside the sieve cylinder 8.

[0037] Moist hydrogen enters the housing 1 through the inlet pipe 2 and then enters the sieve cylinder 8 through the through hole 103. The moisture sieve in the sieve cylinder 8 adsorbs the trace amounts of residual water vapor in the gas through the porous structure or chemical affinity, achieving deep drying. Finally, the dried hydrogen after being treated by the moisture sieve is discharged through the outlet pipe 3 so that it can be subsequently entered into the analyzer. The water level sensor 51 at the bottom of the housing 1 monitors the water level in real time. When the water level reaches the set threshold, the microcontroller triggers the solenoid valve 5 to open, and the water is discharged through the drain pipe 4. After the water level drops to a safe value, the solenoid valve 5 automatically closes to prevent hydrogen leakage and achieve automated management of water accumulation.

[0038] A control rod 6 is mounted inside the housing 1 via bearings, and a frame 7 is fitted around the outer side of the middle portion of the control rod 6. Two sieve cylinders 8 are detachably installed inside the frame 7. An adjusting member 9 is installed at the upper end of the housing 1, and a pressing member 10 is installed at the output end of the adjusting member 9. The pressing member 10 drives the two sieve cylinders 8 inside the frame 7 to correspond to the air outlet 3 and the placement port 11, respectively. Drive bars 61 are evenly distributed on the outer side of the middle portion of the control rod 6, and a limiting plate 62 is provided at the lower part of the drive bars 61. The limiting plate 62 is fixedly fitted around the outer side of the lower end of the control rod 6, and the frame 7 is slidably fitted around the outer side of the drive bars 61. The limiting plate 62 is used to limit the lowest position of the frame 7. The adjusting member 9 includes a guide rod 91 fixed inside the housing 1. The adjusting component 9 also includes a threaded rod 92 mounted inside the housing 1 via a bearing; the pressing component 10 includes a support plate 101 located below the frame 7, with sleeves 102 fixed at both ends of the support plate 101, a through hole 103 extending through the right side of the support plate 101, and a sealing plate 104 fixed on the left side of the support plate 101. A sealing ring 105 is fixed to the outer side of the upper end of the through hole 103 and the sealing plate 104, and a sealing ring 106 is fixed to the upper end of the two sleeves 102; the sleeve 102 on the front side is threadedly connected to the threaded rod 92, and the sleeve 102 on the rear side is slidably connected to the guide rod 91; two sealing rings 12 are installed on the inner wall of the upper end of the housing 1, which fit tightly against the sealing rings 12 when the frame 7 moves upward.

[0039] When the moisture in the right-side screen cylinder 8 is saturated, the adjusting component 9 drives the top pressure component 10 to move downward. After the top pressure component 10 is no longer in effect, the frame 7 moves away from the sealing ring 3 12 under the action of gravity. The frame 7 then fits with the limiting plate 62. The top pressure component 10 continues to move downward until the frame 7 is far away from the sealing ring 105. Then, the control rod 6 is driven to rotate. The control rod 6 drives the frame 7 to rotate through the drive bar 61, causing the screen cylinder 8, which was originally located on the right side after regeneration, to rotate below the air outlet 3. The screen cylinder 8, which was originally located on the right side, rotates to the placement port 11. Then, the threaded rod 92 is driven to rotate, causing the top pressure component 10 to move upward, so that the upper and lower ends of the frame 7 fit tightly with the sealing ring 3 12 and the sealing ring 105 respectively. At the same time, the sleeve 102 fits tightly with the sealing ring 2 106, improving the sealing performance. Then, the screen cylinder 8, which was originally on the right side, can be taken out from the placement port 11 for drying and regeneration, shortening the downtime.

[0040] Working principle: When using the water removal device of this hydrogen oxygen analyzer, if... Figure 1-5 As shown, moist hydrogen gas enters the housing 1 through the inlet pipe 2 and then flows into the right-side sieve cylinder 8. The moisture sieve in the sieve cylinder 8 adsorbs the trace amounts of residual water vapor in the gas through its porous structure or chemical affinity, achieving dehydration and drying. The gas is then discharged through the outlet pipe 3. When the moisture sieve in the right-side sieve cylinder 8 is saturated, the adjusting component 9 drives the top pressure component 10 to move downward. Then, the control rod 6 drives the frame 7 to rotate, which in turn drives the top pressure component 10 to move upward, causing the upper and lower ends of the frame 7 to fit tightly with the sealing ring, improving the sealing performance. The original right-side sieve cylinder 8 can then be removed from the placement port 11 for drying and regeneration, shortening downtime. In addition, the water level sensor 51 at the bottom of the housing 1 monitors the water level in real time. When the water level reaches the set threshold, the microcontroller triggers the solenoid valve 5 to open, and the water is discharged through the drain pipe 4. After the water level drops to a safe value, the solenoid valve 5 automatically closes to prevent hydrogen leakage and achieve automated water management.
