Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen purification devices, and in particular to a hydrogen purification and enhancement device. Background Technology

[0002] Hydrogen-cooled generator units in power plants can effectively reduce heat loss in generator windings and thus improve power generation efficiency through hydrogen cooling. Losses caused by winding impedance are called ventilation losses, and even generators slightly contaminated by oil, gas, water, and air will experience increased ventilation losses. Data shows that a 1% decrease in hydrogen purity leads to a 12% increase in losses; therefore, increasing hydrogen purity means reducing production costs. However, decreased hydrogen purity and increased moisture content can also pose risks to the safe operation of generators.

[0003] For example, Chinese utility model patent application number 202022029365.0 discloses a hydrogen purification and upgrading device, including a main body, a purification membrane module, an oil-water separator, and a filter. A controller is installed on the inner front left end of the main body, and an instrument panel is installed on the inner front right end. From left to right, the upper end of the main body has an exhaust port, an inlet, and a discharge box, with a solenoid valve installed at the lower end of the discharge box. Compared with existing ordinary hydrogen purification devices, this hydrogen purification and upgrading device significantly improves the overall performance while increasing the structure. The improved device has an internal iron powder and oxygen reaction structure, which helps to initially improve the purity of hydrogen. The purification membrane module uses membrane separation technology to separate impurities such as oxygen, nitrogen, and carbon dioxide from the hydrogen. The drying tower dries the hydrogen and reduces its humidity, thereby improving hydrogen purity and reducing oxygen humidity, ensuring that the hydrogen purity and humidity are within the standard specified range.

[0004] The aforementioned patent uses desiccants to dry the moisture in the gas, but its sustainability is poor. The desiccant will become saturated and ineffective after a period of use, requiring frequent replacement by staff, which not only increases production costs but also the workload of staff.

[0005] Therefore, it is necessary to provide a hydrogen purification and upgrading device to solve the above-mentioned technical problems. Utility Model Content

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a hydrogen purification and upgrading device, comprising a mounting frame and a purification membrane module, a flame arrester, an activated carbon canister, a compressor, and an electrical box installed inside the mounting frame. The inlet of the compressor is connected to the activated carbon canister via pipe one, and the outlet of the compressor is connected to the purification membrane module via pipe two. The top of the purification membrane module is connected to the flame arrester via pipe three, and the top of the flame arrester is fixedly connected to a discharge pipe. One side of the purification membrane module is fixedly connected to pipe four. A filter box is fixedly installed on the top of the frame. Pipeline 5 and air inlet pipe are fixedly connected to the left and right sides of the filter box, respectively. The end of pipeline 5 away from the filter box is connected to the activated carbon canister. A support plate is fixedly connected to the left side of the inner wall of the filter box. A baffle is fixedly connected to the top of the support plate. A partition is fixedly connected between the right side of the baffle and the top of the support plate. Water-absorbing sponges are provided on the top of the support plate and on the front and rear sides of the partition. A water-squeezing mechanism is also provided inside the filter box for sequentially squeezing water from the two water-absorbing sponges.

[0008] As a further description of the above technical solution: a desiccant is provided on the top of the support plate and on the left side of the baffle.

[0009] As a further description of the above technical solution: a filter plate is movably inserted inside the filter box and to the right of the absorbent sponge.

[0010] As a further description of the above technical solution: the top of the filter box is hinged to a cover, and a latch is provided between the cover and the filter box.

[0011] As a further description of the above technical solution: a drain hopper is fixedly connected to the bottom of the filter box and at the position corresponding to the support plate, and a water collection tank is threadedly connected to the bottom end of the drain hopper.

[0012] As a further description of the above technical solution: the baffle is provided with a number of inclined ventilation holes, and the top of the support plate and the right side of the baffle are provided with a number of drainage holes.

[0013] As a further description of the above technical solution: the dewatering mechanism includes a drive motor and a transmission gear. The transmission gear is rotatably mounted on a partition plate. Two transmission racks mesh with the outer surface of the transmission gear. Support bars are fixedly connected to the bottom of each of the two transmission racks. The support bars are slidably mounted on the partition plate, and a perforated dewatering plate is fixedly connected to one end of the support bars. The drive motor is fixedly mounted at the bottom of the filter box. A drive disk is fixedly connected to the output end of the drive motor. A connecting rod is hinged to the top of the drive disk near the edge. The end of the connecting rod away from the drive disk is hinged to one of the support bars.

[0014] This utility model has the following beneficial effects:

[0015] 1. Compared with existing technologies, this hydrogen purification and upgrading device, through the setting of water-absorbing sponge, can first remove some of the moisture in the gas, significantly reducing the water content in the gas. This extends the time for the desiccant to reach saturation during the secondary adsorption treatment of moisture in the gas, thereby reducing the frequency of desiccant replacement. This not only reduces production costs but also reduces the workload of workers.

[0016] 2. Compared with existing technologies, this hydrogen purification and upgrading device, through the setting of the water squeezing mechanism, can squeeze two water-absorbing sponges. When one water-absorbing sponge is under compression, the other water-absorbing sponge is in a natural state, which avoids the two water-absorbing sponges being squeezed and compacted at the same time, thus affecting the normal flow of gas. Furthermore, by squeezing the water-absorbing sponges through the hollow water-squeezing plate, the water adsorbed inside the water-absorbing sponge can be squeezed out, reducing the water content in the water-absorbing sponge. This ensures that the water-absorbing sponge can continuously and efficiently remove moisture from the gas, thereby improving the efficiency and effect of moisture removal from the gas.

[0026] 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.

[0027] Reference Figure 1-7 This utility model provides a hydrogen purification and enhancement device, comprising a mounting frame 1 and a purification membrane module 2, a flame arrester 3, an activated carbon canister 4, a compressor 5, and an electrical box 6 installed inside the mounting frame 1. The electrical box 6 has a control panel and an instrument panel mounted on its front. The control panel is electrically connected to the various electrical devices inside the mounting frame 1 and is used to control the start and stop of the electrical devices. The inlet of the compressor 5 is connected to the activated carbon canister 4 via pipe 7, and the outlet of the compressor 5 is connected to the purification membrane module 2 via pipe 8. The top of the purification membrane module 2 is connected to the flame arrester 3 via pipe 9, and the top of the flame arrester 3 is fixedly connected to a discharge pipe 10. One side of the purification membrane module 2 is fixedly connected to a pipe 11. A filter box 12 is fixedly installed on the top of the mounting frame 1. Pipeline 13 and air inlet pipe 14 are fixedly connected to the left and right sides of the filter box 12, respectively. The end of pipeline 13 away from the filter box 12 is connected to the activated carbon canister 4. A support plate 15 is fixedly connected to the left side of the inner wall of the filter box 12. A baffle 16 is fixedly connected to the top of the support plate 15. A partition 17 is fixedly connected between the right side of the baffle 16 and the top of the support plate 15. Water-absorbing sponges 18 are provided on the top of the support plate 15 and on the front and rear sides of the partition 17. A water-squeezing mechanism for squeezing water from the two water-absorbing sponges 18 is also provided inside the filter box 12. A desiccant 19 is provided on the top of the support plate 15 and on the left side of the baffle 16.

[0028] The purification membrane module equipment 2, flame arrester 3, activated carbon tank 4, compressor 5, electrical box 6, pipeline 1 7, pipeline 2 8, pipeline 3 9, discharge pipe 10, pipeline 4 11, filter box 12, pipeline 5 13, air inlet pipe 14, support plate 15, baffle 16, partition 17, water-absorbing sponge 18, etc. are all integrated and installed on a single mounting frame 1, which facilitates installation, use and maintenance.

[0029] By using the absorbent sponge 18, some of the moisture in the gas can be absorbed first, significantly reducing the water content in the gas. This extends the time it takes for the desiccant 19 to reach saturation during the secondary adsorption of moisture in the gas, thereby reducing the frequency of desiccant 19 replacement. This not only reduces production costs but also lightens the workload for workers.

[0030] A filter plate 20 is movably inserted inside the filter box 12 and to the right of the absorbent sponge 18. The filter plate 20 can filter and intercept particulate impurities in the gas.

[0031] A cover 21 is hinged to the top of the filter box 12. A latch 22 is provided between the cover 21 and the filter box 12. The latch 22 can lock the cover 21 to the top of the filter box 12. When it is necessary to replace or clean the desiccant 19, absorbent sponge 18 and filter plate 20 in the filter box 12, the worker first releases the latch 22 from the cover 21, and then flips the cover 21 upwards, so that the top of the filter box 12 is in the open state. At this time, the worker can replace or clean the desiccant 19, absorbent sponge 18 and filter plate 20 in the filter box 12.

[0032] A drain hopper 23 is fixedly connected to the bottom of the filter box 12 at the position corresponding to the support plate 15. A water collection tank 24 is threadedly connected to the bottom end of the drain hopper 23. The water collection tank 24 is used to collect the water squeezed off the absorbent sponge 18 for subsequent unified dumping.

[0033] The baffle 16 has several inclined vent holes 32. The high end of the vent holes is located on the side close to the desiccant 19, and the bottom end of the vent holes is located on the side close to the absorbent sponge 18. The top of the support plate 15 and the right side of the baffle 16 have several drainage holes. The inclined vent holes 32 can ensure that the gas can pass through the baffle 16 normally, and can also prevent the water squeezed out by the hollow water squeezing plate 29 from flowing from the vent holes to the side of the desiccant 19 when it squeezes the absorbent sponge 18.

[0034] The dewatering mechanism includes a drive motor 25 and a transmission gear 26. The transmission gear 26 is rotatably mounted on the partition 17. Two transmission racks 27 mesh on the outer surface of the transmission gear 26. Support bars 28 are fixedly connected to the bottom of each of the two transmission racks 27. The support bars 28 are slidably mounted on the partition 17, and a hollow dewatering plate 29 is fixedly connected to one end of the support bars 28. The drive motor 25 is fixedly mounted at the bottom of the filter box 12. A drive disk 30 is fixedly connected to the output end of the drive motor 25. A connecting rod 31 is hinged at the top of the drive disk 30 near the edge. The end of the connecting rod 31 away from the drive disk 30 is hinged to one of the support bars 28.

[0035] The water-squeezing mechanism allows for the compression of two absorbent sponges 18. While one sponge 18 is being compressed, the other remains in its natural state. This prevents both sponges from being compressed and becoming compacted, which could hinder the normal flow of gas. Furthermore, the perforated water-squeezing plate 29 squeezes out the water absorbed inside the sponge 18, reducing its moisture content and ensuring that the sponge 18 can continuously and efficiently remove moisture from the gas, thus improving the efficiency and effectiveness of moisture removal.

[0036] Working principle: When using this hydrogen purification and refining device, the operator can first control the various devices inside the mounting frame 1 through the control panel. The instrument panel can be used to understand the operation of each device. The exhaust gas generated by the generator can be input into the filter box 12 through the air inlet pipe 14. Large particulate impurities in the gas are filtered through the filter plate 20. Then, the water-absorbing sponge 18 adsorbs the moisture in the gas. After the gas has undergone preliminary dehumidification and impurity removal, it flows through the desiccant 19. The desiccant 19 performs secondary dehumidification treatment on the remaining small amount of moisture in the gas. Then, the gas is transported to the activated carbon tank 4 through pipeline 5 13. The activated carbon in the activated carbon tank 4 can filter out trace amounts of oil, dust and other impurities in the gas. Subsequently, through the cooperation of pipeline 1 7, compressor 5 and pipeline 2 8, the filtered gas is transported to the purification membrane device 2. The purification membrane device 2 purifies the hydrogen in the gas. The purified hydrogen can be transported to the generator for reuse through pipeline 4 11. The remaining exhaust gas is isolated from the ignition source in the gas by the flame arrester 3 and discharged through the discharge pipe 10.

[0037] During the process of the absorbent sponge 18 adsorbing and filtering moisture in the gas, the drive motor 25 is turned on via the control panel. The output end of the drive motor 25 rotates, causing the drive disc 30 to rotate. This, in turn, drives the support bar 28, which is hinged to the support bar 28, to move back and forth. Simultaneously, the transmission rack 27, which is fixedly connected to the support bar 28, moves synchronously. At the same time, the transmission gear 26 drives another transmission rack 27 to move, so that the two transmission racks 27 always move in opposite directions. This, in turn, drives the two hollowed-out water-squeezing plates 29 to sequentially apply water to the two absorbent sponges. The sponge 18 is squeezed, and while one of the absorbent sponges 18 is under compression, the other absorbent sponge 18 remains in its natural state (i.e., uncompressed). This prevents both absorbent sponges 18 from being compressed and becoming compacted, which would affect the normal flow of gas. Furthermore, the perforated squeezing plate 29 squeezes the absorbent sponge 18, squeezing out the water absorbed inside the absorbent sponge 18 and reducing its water content. This ensures that the absorbent sponge 18 can continuously and efficiently remove moisture from the gas, improving the efficiency and effectiveness of moisture removal.
