Description

Technical Field

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

[0002] Hydrogen is an environmentally friendly energy source that is widely used in industrial production and other fields. When hydrogen is produced by hydrolysis, the produced hydrogen contains a certain amount of water. Therefore, separation and purification equipment is needed to purify the hydrogen to improve its purity to meet market demand.

[0003] Chinese patent CN116020250B discloses a hydrogen purification device for the hydrolysis hydrogen production process. The device utilizes the physical property of the boiling point of hydrogen to pump the raw liquid into a low-temperature condensation box through a liquid pump. Under the action of the refrigeration plate, the hydrogen begins to boil and vaporize. The boiling and vaporization process of the hydrogen irregularly floats up in the liquid, driving the irregular swing of the refrigeration plate, which can increase the sufficient disturbance of the raw liquid and improve the internal hydrogen purification and vaporization process. However, the water 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 pump continues to inject the raw liquid into the low-temperature condensation box, the ice cubes in the low-temperature condensation box will gather more and more, which will not only occupy the space in the low-temperature condensation box and reduce the volume of the raw liquid, thereby reducing the hydrogen purification efficiency, but also hinder the swing of the refrigeration plate, affecting the normal operation of the device.

The blocking block 51 is arranged on the filter disc 41 to gather the ice cubes on the filter disc 41. The blocking block 51 is installed with a transmission belt 53. The transmission belt 53 cooperates with the transmission shaft 21. A plurality of pusher 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 pusher plate 54 moves around the blocking block 51 on the filter disc 41. A plurality of refrigeration plates 72 are provided in the purification chamber 7. 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.

[0030] Among them, when in use, the equipment is first started, and then the raw gas produced by hydrolysis to produce hydrogen is compressed into raw liquid through the compressor, and enters the tank body 1 of the equipment 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 enters the storage chamber 6 through the filter disc 41. 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 toward the blocking block 51 in the separation chamber 4. During the rotation of the filter disc 41, the filter disc 41 will bring the ice cubes retained on it to 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. , thereby cleaning the filter disc 41 without affecting subsequent use, and the rotating transmission shaft 21 will also drive the transmission belt 53 to rotate on the blocking block 51, so that the push plate 54 is driven by the transmission belt 53 to move around the blocking block 51, and the ice cubes gathered on the side of the blocking block 51 are pushed out of the separation chamber 4, and 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 is converted 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 rotating refrigeration plate 72 in the purification chamber 7 will disturb the raw liquid in the purification chamber 7, thereby improving the efficiency of converting liquid hydrogen into gaseous hydrogen.

[0031] The difference from the above embodiment is that the transmission assembly 2 also includes a drive motor 23, which is fixedly installed at the bottom of the tank body 1. The output shaft of the drive motor 23 is coaxially fixedly connected to the lower end of the transmission shaft 21, and a transmission gear 22 is coaxially fixedly installed on the upper end of the transmission shaft 21. The transmission gear 22 is located on the upper side of the blocking block 51, and the transmission shaft 21 drives the transmission gear 22 to rotate synchronously.

[0032] 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.

[0033] 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 is connected to the inside of the separation chamber 4, the lower end of the feed port 11 is suspended above the filter disc 41, and the lower end of the feed port 11 is located on the side of the drive shaft 21, the filter disc 41 is rotatably installed on the lower side of the separation chamber 4, and a number of filter holes are evenly arranged on the filter disc 41. The filter holes on the filter disc 41 can filter out ice cubes in the raw liquid. The filter disc 41 is coaxially fixedly connected to the upper end of the drive shaft 21, and a slot 42 is provided on the side of the separation chamber 4, and the slot 42 is located on the other side of the drive shaft 21.

[0034] The difference from the above embodiment is that one end of the blocking block 51 is rotatably connected to the transmission shaft 21, and the other end of the blocking block 51 extends out from the slot 42. The lower side of the blocking block 51 abuts against the upper side of the filter disc 41, and the blocking block 51 is horizontally blocked on the side of the filter disc 41 away from the feed port 11. The upper side of the other end of the blocking block 51 is fixedly connected to the connecting shaft 511, and a driven gear 52 is rotatably installed on the connecting shaft 511. The transmission belt 53 is a toothed belt, which is connected to the transmission gear 22 and the driven gear 52 through teeth. A number of push plates 54 are evenly fixedly connected to the outside of the transmission belt 53, and the push plates 54 are inclined on the transmission belt 53. The push plates 54 are tightly attached to the outside of the blocking block 51 toward one end of the blocking block 51, and the lower side of the push plates 54 is attached to the filter disc 41.

[0035] Among them, 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 push plate 54 to move around the side of the blocking block 51. During the movement of the push plate 54, the push plate 54 will push the ice cubes gathered on the side of the blocking block 51 to move toward the notch 42. Among them, the inclined push plate 54 can prevent the ice cubes from easily separating from the push plate 54 during the movement toward the notch 42. After the push plate 54 sends the ice cubes out of the notch 42, the ice cubes separate from the push plate 54 and fall downward, and the push plate 54 will start to push new ice cubes out of the separation chamber 4 again under the drive of the transmission belt 53.

[0036] The difference from the above embodiment is that the upper end of the storage chamber 6 is open and fixedly connected to the lower end of the separation chamber 4. A guide tube 61 is fixedly installed at the bottom of the storage chamber 6 near the feed port 11. The guide tube 61 is close to the inner wall of the storage chamber 6. The lower end of the guide tube 61 passes through the bottom of the purification chamber 7, and there is a gap between the lower end of the guide tube 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. Several refrigeration plates 72 are evenly and orderly fixedly connected to the outside 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 guide tube 61.

[0037] When purifying hydrogen, the raw liquid that has completed filtration and separation will fall into the storage chamber 6 and flow into the purification chamber 7 through the guide pipe 61. The rotating transmission shaft 21 drives the refrigeration plate 72 thereon through the fixed sleeve 71 to stir in the raw liquid, so that the temperature in the purification chamber 7 can transform the liquid hydrogen into gaseous hydrogen and accelerate the gasification rate of the liquid hydrogen.

[0038] The difference from the above embodiment is that a gas collecting box 8 is fixedly installed on the upper side of the purification chamber 7, and the bottom of the gas collecting box 8 is connected to the top of the purification chamber 7 through a filter membrane 81. The filter membrane 81 can allow gaseous hydrogen to pass through, and one side of the gas collecting box 8 is connected to an exhaust port 82.

[0039] Among them, when 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 to be further purified, then enters the gas collecting chamber and is discharged from the tank body 1 through the exhaust port 82 connected to the gas collecting chamber.

[0040] The difference from the above embodiment is that the collection assembly 5 further includes a collection box 55 , which is fixedly mounted on the top of the gas collecting box 8 , a drain outlet 551 is fixedly connected to the bottom side of the collection box 55 , and a drain valve 552 is fixedly mounted on the drain outlet 551 .

[0041] Among them, after the equipment is started, the ice cubes discharged from the slot 42 will fall into the collection box 55 and be collected by the collection box 55. After the work is completed and the equipment is shut down, the worker 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 again for next use.

[0042] The difference from the above embodiment is that a collecting channel 12 is opened on the tank body 1, the upper end of the collecting channel 12 is connected to the slot 42, and the lower side of the blocking block 51 extending from the slot 42 is fixedly connected to the upper end of the collecting channel 12, and the lower end of the collecting channel 12 is connected to the collecting box 55.

[0043] When ice cubes fall from the slot 42 , they are guided by the collecting channel 12 into the collecting box 55 and collected. The fixed blocking block 51 does not rotate with the transmission shaft 21 , so that the filter disc 41 can be scraped and cleaned.

[0044] The difference from the above embodiment is that a refrigerator 9 is installed in the tank body 1 and is located outside the separation chamber 4 . The refrigerator 9 can reduce the temperature in the separation chamber 4 through the refrigerant.

[0045] After the equipment is started, the refrigerator 9 lowers the temperature in the separation chamber 4 through the refrigerant, so that the raw material liquid can continue to remain in a liquid state in the separation chamber 4.

[0046] The present invention also provides a purification method for producing hydrogen by hydrolysis, which uses a separation and purification device.

[0047] Working principle: When in use, first start the device, drive the motor 23 to drive the transmission shaft 21 to rotate, and the rotating transmission shaft 21 drives the transmission gear 22 to rotate, and then the raw gas produced by hydrolysis hydrogen production is compressed into raw liquid through the compressor, and enters the tank body 1 of the device from the feed port 11. The refrigerator 9 reduces the temperature in the separation chamber 4 through the refrigerant, so that the raw liquid can continue to remain in a liquid state in the separation chamber 4. 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 will be filtered out by the filter disc 41, leaving The ice cubes on the filter disc 41 are blocked by the blocking block 51, 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 without affecting subsequent use.

[0048] The ice cubes are then separated from the push plate 54 and fall downwards, and the push plate 54 starts to push new ice cubes out of the separation chamber 4 again under the drive of the transmission belt 53. After the raw material liquid has been filtered and separated, it falls into the storage chamber 6 and flows into the purification chamber 7 through the guide pipe 61. The rotating transmission shaft 21 drives the refrigeration plate 72 thereon through the fixed sleeve 71 in the raw material The liquid is stirred, and the refrigeration plate 72 can control the temperature in the purification chamber 7, so that the liquid hydrogen in the purification chamber 7 is converted into gaseous hydrogen at this temperature, and the refrigeration plate 72 is driven by the transmission shaft 21 to stir the raw liquid in the purification chamber 7, which can accelerate the gasification rate of the liquid hydrogen. After the raw liquid in the purification chamber 7 is gasified into hydrogen, the hydrogen in the purification chamber 7 floats up and passes through the filter membrane 81 for further purification, and then enters the gas collecting chamber, and is discharged from the exhaust port 82 connected to the gas collecting chamber. At the same time, the ice cubes discharged from the groove 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 work is completed and the equipment is shut down, the worker 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 next use.
