Description

Technical Field

[0001] This utility model relates to the technical field of helium purification and drying apparatus, and in particular to a helium purification and drying apparatus. Background Technology

[0002] Natural helium is usually mixed with other gases, such as nitrogen, oxygen, hydrogen, carbon dioxide, and water vapor. The presence of these impurities not only reduces the purity of helium but may also adversely affect its applications. A search revealed a helium purification and drying device (publication number: CN220633674U). This device uses an induced draft fan to guide hot air from the drying tank into a jacket through a hot air duct. Water vapor evaporated from the adsorbent also enters the jacket with the hot air, effectively removing water vapor from the drying tank. By using hot air within the jacket to supplement the heating of the adsorbent, waste heat is effectively utilized, slowing down the rate of heat loss from the adsorbent and maintaining its high temperature to improve drying efficiency. This also reduces the energy consumption of the electric heating device. However, there are drawbacks: although the adsorption method and the use of the adsorbent can achieve purification, the adsorption method is usually used to filter impurities in helium, which are mainly trace amounts of low-boiling-point impurities such as moisture and oil. If the helium contains a large number of high-boiling-point impurities, such as nitrogen and oxygen, they cannot be effectively removed. Furthermore, if some impurities are not removed first by condensation, the impurity content of the gas entering the adsorption stage will not decrease. This increases the amount of adsorbent used and the frequency of replacement, reduces the adsorbent's lifespan, and thus increases costs. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a helium purification and drying device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. Using an operating table, a first base, a first chamber, plates, a cryogenic control box, and cryogenic rods, helium first enters the first chamber before being purified with adsorbent. The cryogenic control box is turned on to activate the cryogenic rods, causing the first chamber to reach a low temperature. When the temperature of high-boiling-point impurities in the helium reaches this temperature, the impurities become liquid. Then, through multiple plates in the first chamber, the liquid flows from top to bottom to the bottom of the first chamber and is discharged through a drain. By using a cryogenic mode to remove some impurities through condensation, the impurity content of the gas entering the adsorption stage is reduced. This reduces the amount of adsorbent used and the frequency of replacement, increases the lifespan of the adsorbent, and thus reduces production costs.

Then, the cover, the cylinder connected to the cover, and the mesh plate box can be directly removed using the handle. This allows for easy replacement of the adsorbent in the mesh plate box, thereby improving work efficiency. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figures 1 to 5A helium purification and drying device includes an operating table 1, on which multiple sets of first bases 2 are mounted. A first chamber 3 is fixedly connected to some of the first bases 2, and the first chamber 3 is used to perform the first purification. Multiple sets of plates 4 are mounted on the first chamber 3, symmetrically arranged from top to bottom, with only a small gap between each plate 4 and the first chamber 3. This slows down the flow of helium, allowing it to remain for a longer time and improving the purification effect. The plates 4 are all designed to be inclined. A low-temperature control box 5 is mounted on the first chamber 3, and two sets of low-temperature rods 6 are mounted on the low-temperature control box 5. The low-temperature rods 6 lower the temperature in the first chamber 3 and condense and filter out impurities in the helium. The two sets of low-temperature rods 6 penetrate the first chamber 3 and the multiple sets of plates 4. A housing 3 is connected to one end of a first pipe 8 and a second pipe 20. Both the first pipe 8 and the second pipe 20 are equipped with induced draft fans 25. Before using the adsorbent to purify helium, helium first enters the first housing 3. By turning on the low-temperature control box 5, the low-temperature rod 6 is activated, causing the first housing 3 to generate a low temperature. When the temperature of the high-boiling-point impurities contained in the helium reaches the temperature, the impurities will turn into liquid. Then, through the multiple sets of plates 4 set in the first housing 3, the liquid can flow from top to bottom to the bottom of the first housing 3. Afterward, it can be discharged through the drain port 7. By using the low-temperature mode to remove some impurities by condensation, the content of gas impurities entering the adsorption stage will be reduced, which can reduce the amount of adsorbent used and the replacement frequency, improve the service life of the adsorbent, and reduce production costs.

[0023] In this embodiment, the other ends of the first tube 8 and the second tube 20 are connected to a second housing 9. The second housing 9 is used to complete the second purification of helium. A cover 10 is attached to the second housing 9 to seal it. The second housing 9 has two sets of grooves 11 and two sets of bolts 12 are threaded to it. The two sets of bolts 12 are threaded to two sets of blocks 13, which are slidably connected to the corresponding grooves 11. The bolts 12 and the corresponding blocks 13 can restrict the position of the cover 10 on the second housing 9. A heater 14 is installed on the cover 10. The model of the heater 14 is selected according to the actual working requirements. A cylinder 15 is installed on the cover 10, and a heating rod 16 is installed on the heater 14. The heating rod 16 penetrates the cover 10 and is clearance-fitted with the cylinder 15. A mesh box 17 is threaded to the cylinder 15. The mesh box 17 has openings... Multiple sets of holes are present. The mesh box 17 is filled with an adsorbent that can adsorb impurities such as moisture and oil in the gas. The mesh box 17 is attached to the second box 9. The heating rod 16 passes through the mesh box 17. The second base 18 is fixedly connected to the bottom of the second box 9 and is connected to the operating table 1. One end of the fourth tube 22 is connected to the second box 9, and the other end of the fourth tube 22 is connected to the third box 26. The third box 26 is used to store the purified helium. The third box 26 is connected to multiple sets of first bases 2. The fourth tube 22 is connected to another set of induced draft fans 25. The first box 3 is equipped with a drain outlet 7. The cover 10 is equipped with two sets of handles 19. The first box 3 is connected to the third tube 21. The third box 26 is connected to the fifth tube 23. The cover 10 is equipped with a rubber gasket 24. The cover 10 and the rubber gasket 24 can more effectively seal the second box 9.

[0024] The working principle of this embodiment is as follows: First, open the valve on the third tube 21 to allow helium to enter the first chamber 3. Then, open the cryogenic control box 5 on the first chamber 3 to lower the temperature of the cryogenic rod 6. When a certain temperature is reached, impurities in the helium will liquefy. The liquefied impurities will fall through the plate 4 in the first chamber 3 to the bottom of the first chamber 3 and can be discharged through the drain 7 below. Then, close the valve on the third tube 21 and open the valve on the first tube 8. The induced draft fan 25 then draws helium into the second chamber 9. The helium will pass through the adsorbent in the mesh box 17 for a second filtration, where the adsorbent will filter out moisture, oil, and other impurities from the gas. Then, close the valve on the first tube 8 and open the valve on the fourth tube 22 and the induced draft fan 25 on the fourth tube 22 to draw the filtered helium into the second chamber 9. Inside the third chamber 26, after closing the valve on the fourth pipe 22, the heater 14 on the cover 10 is opened. The heater 14 heats the heating rod 16, which evaporates the moisture and other impurities in the adsorbent in the mesh box 17. The valve on the second pipe 20 is then opened, and the blower 25 on the second pipe 20 is turned on to draw the steam impurities in the second chamber 9 into the first chamber 3. The steam will become liquid due to the low-temperature rod 6 in the first chamber 3, and will eventually be discharged through the drain 7. When the adsorbent needs to be replaced, the block 13 can be brought into the trough 11 on the second chamber 9 by turning the bolt button 12. Then, the cover 10, the cylinder 15 connected to the cover 10, and the mesh box 17 can be directly removed through the handle 19, which makes it easy to replace the adsorbent in the mesh box 17, thereby improving work efficiency.
