Description

Technical Field

[0001] The present invention relates to the technical field of separation equipment, and specifically to a separation and purification equipment and a purification method for hydrogen production by hydrolysis. Background Art

[0002] Hydrogen is an environmentally friendly energy source and is widely used in industrial production and other fields. Among them, when hydrogen is produced by hydrolysis, the produced hydrogen contains a certain amount of moisture. Therefore, a separation and purification equipment is needed to purify the hydrogen, so as to improve the purity of hydrogen to meet the market demand; Chinese Patent CN116020250B discloses a hydrogen purification device in the process of hydrogen production by hydrolysis. This equipment utilizes the physical property of the boiling point of hydrogen. The raw liquid is pumped into the low-temperature condensation box by a liquid pumping pump. Under the action of the refrigeration plate, hydrogen begins to boil and gasify. During the process of boiling and gasifying of hydrogen, it irregularly floats upward in the liquid, driving the irregular swing of the refrigeration plate, which can improve the full disturbance of the raw liquid, and improve the internal hydrogen purification and gasification process. However, the moisture contained in the raw liquid in the low-temperature environment of the low-temperature condensation box will freeze into ice cubes and mix in the raw liquid. As the liquid pumping pump continuously injects the raw liquid into the low-temperature condensation box, the ice cubes in the low-temperature condensation box will accumulate more and more. This will not only occupy the space in the low-temperature condensation box, reduce the volume of the raw liquid, thereby reducing the purification efficiency of hydrogen, but also obstruct the swing of the refrigeration plate, affecting the normal operation of the device.

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-8 , a separation and purification device and a purification method for hydrogen production by hydrolysis, comprising a tank body 1, on which a feed inlet 11 and an exhaust port 82 are sequentially installed. It is characterized in that: a transmission assembly 2, a purification mechanism 3 and a collection assembly 5 are arranged on the tank body 1. The transmission assembly 2 includes a transmission shaft 21 installed in the tank body 1, and the transmission shaft 21 can rotate in the tank body 1. The purification mechanism 3 includes a separation chamber 4, a collection assembly 5, a storage chamber 6 and a purification chamber 7. The separation chamber 4, the storage chamber 6 and the purification chamber 7 are sequentially installed in the tank body 1 from the upper end of the tank body 1. The transmission shaft 21 sequentially penetrates through the purification chamber 7, the storage chamber 6 and the separation chamber 4. The two ends of the transmission shaft 21 are respectively located in the separation chamber 4 and at the bottom of the purification chamber 7. A filter disk 41 is provided in the separation chamber 4, and the filter disk 41 can filter out the ice cubes mixed in the raw material liquid. The filter disk 41 is connected to the upper end of the transmission shaft 21, and the transmission shaft 21 can drive the filter disk 41 to rotate. The collection assembly 5 includes a blocking block 51, a transmission belt 53 and a pushing plate 54. The blocking block 51 is arranged on the filter disk 41 for gathering the ice cubes on the filter disk 41. A transmission belt 53 is installed on the blocking block 51, and the transmission belt 53 cooperates with the transmission shaft 21. A plurality of pushing plates 54 are connected to the transmission belt 53. When the transmission shaft 21 rotates, it can drive the transmission belt 53 to rotate, so that the pushing plates 54 move around the blocking block 51 on the filter disk 41. A plurality of refrigeration plates 72 are provided in the purification chamber 7, and the refrigeration plates 72 are connected to the transmission shaft 21. The transmission shaft 21 can drive the refrigeration plates 72 to rotate in the purification chamber 7.

[0021] Among them, when in use, first start the device, and then compress the raw gas produced by hydrolysis hydrogen production into a raw liquid through a compressor and enter the tank body 1 of the device from the feed port 11. The raw liquid in the feed port 11 will fall to the side of the filter disc 41, and the ice cubes mixed in the raw liquid are filtered out by the filter disc 41 and remain on the filter disc 41, while the raw liquid passes through the filter disc 41 and enters the storage chamber 6. At the same time, the transmission shaft 21 of the transmission assembly 2 rotates, and the upper end of the transmission shaft 21 drives the filter disc 41 to rotate in the separation chamber 4 towards the blocking block 51. During the rotation of the filter disc 41, the filter disc 41 will carry the ice cubes remaining on it towards the side of the blocking block 51, and the blocking block 51 blocks the ice cubes on the filter disc 41, so that the ice cubes no longer move with the filter disc 41 and gather on the side of the blocking block 51, thus cleaning the filter disc 41 and not affecting subsequent use. Moreover, the rotating transmission shaft 21 will also drive the transmission belt 53 to rotate on the blocking block 51, so that the pushing plate 54 moves around the blocking block 51 driven by the transmission belt 53, and pushes the ice cubes gathered on the side of the blocking block 51 out of the separation chamber 4. The raw liquid filtered by the filter disc 41 enters the purification chamber 7 through the storage chamber 6. At this time, the rotating transmission shaft 21 also drives the refrigeration plate 72 to rotate in the purification chamber 7. The refrigeration plate 72 can control the temperature in the purification chamber 7, so that the liquid hydrogen in the purification chamber 7 changes into gaseous hydrogen at this temperature. The hydrogen purified by the purification chamber 7 is discharged into the next process. At the same time, the refrigeration plate 72 rotating in the purification chamber 7 will disturb the raw liquid in the purification chamber 7, thereby improving the efficiency of the liquid hydrogen changing into gaseous hydrogen.

[0022] The difference from the above embodiment is that the transmission assembly 2 further includes a driving motor 23. The driving motor 23 is fixedly installed at the bottom inside the tank body 1. The output shaft of the driving motor 23 is coaxially and fixedly connected to the lower end of the transmission shaft 21. A transmission gear 22 is coaxially and fixedly installed at the upper end of the transmission shaft 21. The transmission gear 22 is located above the blocking block 51, and the transmission shaft 21 drives the transmission gear 22 to rotate synchronously.

[0023] Among them, after the device is started, the driving motor 23 drives the transmission shaft 21 to rotate, and the rotating transmission shaft 21 drives the transmission gear 22 to rotate.

[0024] The difference from the above embodiment is that the feed port 11 is fixedly connected to the upper end of the tank body 1. The lower end of the feed port 11 communicates with the inside of the separation chamber 4. The lower end of the feed port 11 hangs above the filter disc 41, and the lower end of the feed port 11 is located on the side of the transmission shaft 21. The filter disc 41 is rotatably installed at the lower side of the separation chamber 4. A number of filter holes are evenly arranged on the filter disc 41. The filter holes on the filter disc 41 can filter out the ice cubes in the raw liquid. The filter disc 41 is coaxially and fixedly connected to the upper end of the transmission shaft 21. A notch 42 is opened on the side of the separation chamber 4, and the notch 42 is located on the other side of the transmission shaft 21.

[0025] The difference from the above embodiment is that one end of the blocking block 51 is rotatably connected to the transmission shaft 21, the other end of the blocking block 51 extends out of the notch 42, the lower side of the blocking block 51 abuts against the upper side of the filter disk 41, the blocking block 51 horizontally blocks the side of the filter disk 41 away from the feed port 11, a connecting shaft 511 is fixedly connected to the upper side of the other end of the blocking block 51, a driven gear 52 is rotatably installed on the connecting shaft 511, the transmission belt 53 is a toothed belt and is connected to the driving gear 22 and the driven gear 52 through teeth, a plurality of pushing plates 54 are uniformly fixedly connected to the outer side of the transmission belt 53, and the pushing plates 54 are inclined on the transmission belt 53. The end of the pushing plate 54 facing the blocking block 51 is closely attached to the outer side of the blocking block 51, and the lower side of the pushing plate 54 is attached to the filter disk 41.

[0026] Among them, when the transmission shaft 21 drives the driving gear 22 to rotate, the driving gear 22 cooperates with the driven gear 52 at the other end of the blocking block 51 to drive the transmission belt 53 to drive the pushing plate 54 to move around the side of the blocking block 51. During the movement of the pushing plate 54, the pushing plate 54 will push the ice cubes gathered on the side of the blocking block 51 towards the notch 42. Among them, the inclined pushing plate 54 can prevent the ice cubes from easily detaching from the pushing plate 54 during the movement towards the notch 42. After the pushing plate 54 sends the ice cubes out of the notch 42, the ice cubes are separated from the pushing plate 54 and fall downward, while the pushing plate 54 will, under the drive of the transmission belt 53, start to push new ice cubes out of the separation chamber 4 again.

[0027] The difference from the above embodiment is that the upper end of the storage chamber 6 is an opening and is fixedly connected to the lower end of the separation chamber 4. A diversion pipe 61 is fixedly installed at the bottom of the storage chamber 6 on the side close to the feed port 11. The diversion pipe 61 is close to the inner wall of the storage chamber 6. The lower end of the diversion pipe 61 penetrates into the bottom of the purification chamber 7 and there is a gap between the lower end of the diversion pipe 61 and the bottom of the purification chamber 7. A fixed sleeve 71 is provided in the purification chamber 7. The fixed sleeve 71 is coaxially fixedly connected to the transmission shaft 21. A plurality of refrigeration plates 72 are uniformly and orderly fixedly connected to the outer side of the fixed sleeve 71. There is a distance between the end of the refrigeration plate 72 away from the transmission shaft 21 and the diversion pipe 61.

[0028] Among them, when purifying hydrogen, the raw material liquid that has completed filtration and separation will fall into the storage chamber 6 and flow into the purification chamber 7 through the diversion pipe 61. The rotating transmission shaft 21 drives the refrigeration plates 72 thereon to stir in the raw material liquid through the fixed sleeve 71, so that the temperature in the purification chamber 7 can turn liquid hydrogen into gaseous hydrogen and accelerate the gasification speed of liquid hydrogen.

[0029] The difference from the above embodiment is that a gas collection box 8 is fixedly installed on the upper side of the purification chamber 7. The bottom of the gas collection box 8 is communicated with the top of the purification chamber 7 through a filter membrane 81. The filter membrane 81 can allow gaseous hydrogen to pass through. One side of the gas collection box 8 is communicated with an exhaust port 82.

[0030] Among them, after the raw material liquid in the purification chamber 7 is vaporized into hydrogen, the hydrogen in the purification chamber 7 floats up and passes through the filter membrane 81 for further purification, then enters the gas collection chamber, and is discharged from the tank body 1 through the exhaust port 82 communicated with the gas collection chamber.

[0031] The difference from the above embodiment is that the collection assembly 5 further includes a collection box 55. The collection box 55 is fixedly installed on the top of the gas collection box 8. A drain port 551 is fixedly connected to the bottom side of the collection box 55, and a drain valve 552 is fixedly installed on the drain port 551.

[0032] Among them, after the equipment is started, the ice cubes discharged from the notch 42 will fall into the collection box 55 and be collected by the collection box 55. After the equipment is shut down after the work is completed, the worker then opens the drain valve 552, and the ice cubes in the collection box 55 melt into water and are discharged from the drain port 551. After all the water in the collection box 55 is drained, the drain valve 552 is closed for the next use.

[0033] The difference from the above embodiment is that a collection channel 12 is opened on the tank body 1. The upper end of the collection channel 12 is communicated with the notch 42, and the lower side of the blocking block 51 extending out of the notch 42 is fixedly connected to the upper end of the collection channel 12. The lower end of the collection channel 12 is communicated with the collection box 55.

[0034] Among them, when the ice cubes fall from the notch 42, they enter the collection box 55 under the guidance of the collection channel 12 and are collected. The fixed blocking block 51 will not rotate with the transmission shaft 21, so that the filter disc 41 can be scraped and cleaned.

[0035] The difference from the above embodiment is that a refrigerator 9 is installed in the tank body 1. The refrigerator 9 is located outside the separation chamber 4, and the refrigerator 9 can reduce the temperature in the separation chamber 4 through the refrigerant.

[0036] Among them, after the equipment is started, the refrigerator 9 reduces the temperature in the separation chamber 4 through the refrigerant, so that the raw material liquid can continue to remain in the liquid state when it is in the separation chamber 4.

[0037] The present invention also provides a purification method for hydrogen production by hydrolysis, which uses a separation and purification device.

[0038] Working principle: When in use, first start the device. The driving motor 23 drives the transmission shaft 21 to rotate. The rotating transmission shaft 21 drives the transmission gear 22 to rotate. Subsequently, the raw material gas produced by hydrolysis hydrogen production is compressed into a raw material liquid by a compressor and enters the tank body 1 of the device from the feed port 11. The cooler 9 reduces the temperature in the separation chamber 4 through a refrigerant, so that the raw material liquid can continue to remain in a liquid state when in the separation chamber 4. The raw material liquid in the feed port 11 will fall to the side of the filter disc 41, and the ice cubes mixed in the raw material liquid are filtered out by the filter disc 41 and remain on the filter disc 41, while the raw material liquid enters the storage chamber 6 through the filter disc 41. At the same time, as the transmission shaft 21 of the transmission assembly 2 rotates, the upper end of the transmission shaft 21 drives the filter disc 41 to rotate in the separation chamber 4 towards the blocking block 51. During the rotation of the filter disc 41, the filter disc 41 will carry the ice cubes remaining on it towards the side of the blocking block 51. The blocking block 51 blocks the ice cubes on the filter disc 41, so that the ice cubes no longer move with the filter disc 41 and gather on the side of the blocking block 51, thereby cleaning the filter disc 41 and not affecting subsequent use; Moreover, when the transmission shaft 21 drives the transmission gear 22 to rotate, the transmission gear 22 cooperates with the driven gear 52 at the other end of the blocking block 51 to drive the transmission belt 53 to drive the pushing plate 54 to move around the side of the blocking block 51. During the movement of the pushing plate 54, the pushing plate 54 will push the ice cubes gathered on the side of the blocking block 51 towards the notch 42. Among them, the inclined pushing plate 54 can prevent the ice cubes from easily separating from the pushing plate 54 during the movement towards the notch 42. After the pushing plate 54 sends the ice cubes out of the notch 42, the ice cubes separate from the pushing plate 54 and fall downward, while the pushing plate 54 will, under the drive of the transmission belt 53, start to push new ice cubes out of the separation chamber 4 again. After the raw material liquid that has completed filtration separation falls into the storage chamber 6, it flows into the purification chamber 7 through the diversion pipe 61. The rotating transmission shaft 21 drives the refrigerating plate 72 on it to stir in the raw material liquid. The refrigerating plate 72 can control the temperature in the purification chamber 7, so that the liquid hydrogen in the purification chamber 7 changes into gaseous hydrogen at this temperature. And by driving the refrigerating plate 72 to stir the raw material liquid in the purification chamber 7 through the transmission shaft 21, the gasification speed of the liquid hydrogen can be accelerated. When the raw material liquid in the purification chamber 7 gasifies into hydrogen, the hydrogen in the purification chamber 7 floats up, is further purified through the filter membrane 81, and then enters the gas collection chamber. It is discharged from the tank body 1 through the exhaust port 82 communicated with the gas collection chamber. At the same time, the ice cubes discharged from the notch 42 will enter the collection box 55 under the guidance of the collection channel 12 and be collected by the collection box 55. After the device is shut down after completing the work, the worker then opens the drain valve 552, and the ice cubes in the collection box 55 melt into water and are discharged from the drain port 551. After all the water in the collection box 55 is drained, the drain valve 552 is closed for the next use.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
