Description

Technical Field

[0001] This utility model relates to the technical field of hydrogen production equipment by water electrolysis, specifically a dryer for hydrogen production by internal circulation hot regenerated water electrolysis. Background Technology

[0002] Hydrogen production by water electrolysis refers to the electrolysis of pure water-based electrolyte in an electrolytic cell to produce hydrogen and oxygen. When the hydrogen is discharged from the electrolytic cell, it may carry a certain amount of electrolyte. Therefore, it needs to be condensed and washed to remove the electrolyte and then dried to remove any water that may have been mixed in during the washing process.

[0003] The internal circulation thermal regeneration water electrolysis hydrogen production dryer uses the activated alumina and molecular sieve inside the drying tower as adsorbents to remove moisture from hydrogen. After working for a period of time, the adsorbent becomes saturated with water and loses its working capacity. At this time, the moisture can be evaporated and discharged through thermal regeneration, so that the adsorbent can work again to continue adsorbing hydrogen.

[0004] Existing internal circulation thermal regeneration water electrolysis hydrogen production dryers typically use electric heating or other methods to perform thermal regeneration of the adsorbent. Since the adsorption tower is usually made of metal, a large amount of heat is lost during the thermal regeneration process, which affects the regeneration efficiency. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a dryer specifically for hydrogen production via internal circulation thermal regeneration water electrolysis, so as to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a dryer for hydrogen production via internal circulation hot regenerated water electrolysis, comprising a base and a drying tower. The drying tower is externally fitted with a support plate and a heat insulation layer, and a second protective plate is externally fitted with the heat insulation layer. The second protective plate is externally fitted with a sound insulation layer, and a first protective plate is externally fitted with the sound insulation layer. A hoop plate is connected to one side of the support plate and the first protective plate, and a bolt passes through one side of the hoop plate.

[0007] By adopting the above technical solution, during the thermal regeneration process, the use of a heat insulation layer and a sound insulation layer made of slag wool material also provides a certain degree of heat insulation, thereby reducing the heat dissipated from the drying tower to the outside, improving heat utilization, and allowing more heat to be used for the regeneration of the adsorbent to improve regeneration efficiency and indirectly reduce energy consumption. Furthermore, the presence of the sound insulation layer reduces the outward propagation of abnormal noises caused by thermal expansion and contraction inside the drying tower during regeneration, as well as the outward propagation of abnormal noises caused by friction and pressure changes of hydrogen gas passing through the adsorbent during adsorption. The first and second protective plates support and connect the sound insulation and heat insulation layers, improving... High structural stability; when the first protective plate, sound insulation layer, second protective plate, and heat insulation layer are damaged, the workers can loosen the bolts, then pull the hoop plate up or down to stop the restriction on the first and second protective plates, and finally bend and disassemble the first protective plate, sound insulation layer, second protective plate, and heat insulation layer; during installation, the workers first bend the first protective plate, sound insulation layer, second protective plate, and heat insulation layer and put them on the outside of the drying tower, then push the hoop plate up or down to put it on the outside of the support plate and the first protective plate, and finally tighten the bolts to complete the structural fastening and prevent the structure from loosening.

[0008] Furthermore, the heat insulation layer is made of ceramic fiber material.

[0009] By adopting the above technical solution and setting up the heat insulation layer, the heat emitted by the drying tower to the outside can be reduced, thereby improving the heat utilization rate and allowing more heat to be used for the regeneration of the adsorbent to improve the regeneration efficiency and indirectly reduce energy consumption.

[0010] Furthermore, the sound insulation layer is made of slag wool material.

[0011] By adopting the above technical solution, the sound insulation layer is made of slag wool material, which also has a certain heat insulation effect, thereby reducing the heat dissipated from the drying tower to the outside, thus improving the heat utilization rate. In addition, the presence of the sound insulation layer can reduce the abnormal noise generated by thermal expansion and contraction inside the drying tower during regeneration, as well as the abnormal noise generated by hydrogen gas passing through the adsorbent, friction, pressure changes, etc. during adsorption.

[0012] Furthermore, the cross-sections of the top side of the support plate, the first protective plate, and the second protective plate are all T-shaped, and the cross-section of the hoop plate is C-shaped.

[0013] By adopting the above technical solution, the workers push the hoop plate up or down and put it on the outside of the support plate and the first protective plate. Finally, the workers tighten the bolts to complete the fastening of the structure and prevent the structure from loosening.

[0014] Furthermore, the hoop plate is detachably connected to the support plate and the first protective plate by sliding, and the bolts are threadedly connected to the support plate.

[0015] By adopting the above technical solution, when the first protective plate, sound insulation layer, second protective plate and heat insulation layer are damaged, the staff can loosen the bolts, and then the staff can pull out the hoop plate upward or downward to end the restriction on the first and second protective plates.

[0016] Furthermore, the insulation layer is detachably connected to the drying tower.

[0017] By adopting the above technical solution, when the first protective plate, sound insulation layer, second protective plate and heat insulation layer are damaged, the staff can loosen the bolts and pull out the clamp plate. Finally, the staff can bend and disassemble the first protective plate, sound insulation layer, second protective plate and heat insulation layer.

[0018] Furthermore, two drying towers are provided, and the two drying towers are respectively installed on the top two sides of the base. A controller, a lower pipeline and an upper pipeline are respectively provided between the two drying towers.

[0019] By adopting the above technical solution, hydrogen passes through one of the drying towers via the lower and upper pipelines. The adsorbent inside the drying tower absorbs the moisture mixed in with the hydrogen, thereby drying the output hydrogen. When the adsorbent in one drying tower is saturated, the hydrogen passes through another drying tower via the lower and upper pipelines for further drying. Meanwhile, the adsorbent in one drying tower is heated by electric heating or by circulating hot air for thermal regeneration.

[0020] Furthermore, the support plate and bolts are provided in two sets, and the hoop plate, the first protective plate, the sound insulation layer, the second protective plate and the heat insulation layer are provided in twos. The two sets of support plates, the two sets of bolts, the two hoop plates, the two first protective plates, the two sound insulation layers, the two second protective plates and the two heat insulation layers are all mirrored.

[0021] By adopting the above technical solution, and by setting two sets of support plates and bolts, as well as two hoop plates, a first protective plate, a sound insulation layer, a second protective plate, and a heat insulation layer, the corresponding two drying towers can be kept insulated.

[0022] Furthermore, a first temperature sensor is installed on one side of the top of each of the two drying towers, and a second temperature sensor is installed on the lower side of one side of each of the two drying towers, and both the first and second temperature sensors are electrically connected to the controller.

[0023] By adopting the above technical solution, during the thermal regeneration process, the temperature inside the drying tower is monitored by the first and second temperature sensors, so as to send an electrical signal to the controller to control the temperature of electric heating or air heating, and avoid the thermal regeneration temperature from being too high.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A dedicated dryer for hydrogen production via internal circulation hot regeneration water electrolysis, such as... Figures 1-4As shown, the system includes a base 1 and a drying tower 2. A support plate 8 and a heat insulation layer 14 are fitted around the outside of the drying tower 2. The heat insulation layer 14 is made of ceramic fiber material. A second protective plate 13 is fitted around the heat insulation layer 14, and a sound insulation layer 12 is fitted around the second protective plate 13. The sound insulation layer 12 is made of slag wool material. A first protective plate 11 is fitted around the sound insulation layer 12. During the thermal regeneration process, the heat insulation layer 14 and the slag wool material used in the sound insulation layer 12 provide a certain degree of heat insulation, thereby reducing the heat dissipated from the drying tower 2 to the outside, improving heat utilization, and allowing more heat to act on the adsorbent. The regeneration process improves regeneration efficiency and indirectly reduces energy consumption. The presence of the sound insulation layer 12 reduces the outward propagation of abnormal noises caused by thermal expansion and contraction inside the drying tower 2 during regeneration, as well as the outward propagation of abnormal noises caused by friction and pressure changes as hydrogen passes through the adsorbent during adsorption. The first protective plate 11 and the second protective plate 13 support and connect the sound insulation layer 12 and the heat insulation layer 14, improving structural stability. The heat insulation layer 14 is detachably connected to the drying tower 2. A hoop 9 is connected to one side of the support plate 8 and the first protective plate 11. The cross-section of the top side of the support plate 8, the first protective plate 11, and the second protective plate 13 is T-shaped, while the cross-section of the hoop 9 is C-shaped. The hoop plate 9 is detachably connected to the support plate 8 and the first protective plate 11 by sliding. A bolt 10 passes through one side of the hoop plate 9 and is threadedly connected to the support plate 8. When the first protective plate 11, sound insulation layer 12, second protective plate 13, and heat insulation layer 14 are damaged, the worker can loosen the bolt 10. Then, the worker can pull the hoop plate 9 up or down to stop limiting the first protective plate 11 and the second protective plate 13. Finally, the worker can bend and disassemble the first protective plate 11, sound insulation layer 12, second protective plate 13, and heat insulation layer 14. During installation, the worker first removes the first protective plate 11, sound insulation layer 12, and second protective plate 13. The insulation layer 14 is bent and fitted onto the outside of the drying tower 2. Then, the workers push the hoop 9 up or down and fit it onto the outside of the support plate 8 and the first protective plate 11. Finally, the workers tighten the bolts 10 to complete the structural fastening and prevent the structure from loosening. There are two sets of support plates 8 and bolts 10, and two sets of hoop 9, first protective plate 11, sound insulation layer 12, second protective plate 13 and insulation layer 14. The two sets of support plates 8, two sets of bolts 10, two hoop 9, two first protective plates 11, two sound insulation layers 12, two second protective plates 13 and two insulation layers 14 are mirrored and can correspond to the heat insulation work of the two drying towers 2.

[0036] See Figure 1In the above embodiment, two drying towers 2 are provided, which are respectively installed on the top two sides of the base 1. A controller 3, a lower pipe 4 and an upper pipe 5 are respectively provided between the two drying towers 2. Hydrogen gas passes through one of the drying towers 2 through the lower pipe 4 and the upper pipe 5. The adsorbent inside the drying tower 2 absorbs the moisture mixed in with the hydrogen gas, thereby drying the output hydrogen gas. When the adsorbent in one drying tower 2 is saturated, the hydrogen gas passes through the lower pipe 4 and the upper pipe 5 through the other drying tower 2 for drying. The adsorbent in one drying tower 2 is heated by electric heating or circulating hot air to perform thermal regeneration.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are now implemented to improve security.

[0039] See Figure 1 In the above embodiment, a first temperature sensor 6 is installed on one side of the top of each of the two drying towers 2, and a second temperature sensor 7 is installed on the lower side of one side of each of the two drying towers 2. The first temperature sensor 6 and the second temperature sensor 7 are both electrically connected to the controller 3. During the thermal regeneration process, the temperature inside the drying tower 2 is monitored by the first temperature sensor 6 and the second temperature sensor 7 so as to send an electrical signal to the controller 3 to control the temperature of electric heating or air heating and avoid the thermal regeneration temperature from being too high.

[0040] The implementation principle of this utility model is as follows: First, hydrogen gas passes through one of the drying towers 2 via the lower pipe 4 and the upper pipe 5. The adsorbent inside the drying tower 2 absorbs the moisture mixed in with the hydrogen gas, thereby drying the output hydrogen gas. When the adsorbent in one drying tower 2 is saturated, the hydrogen gas passes through the lower pipe 4 and the upper pipe 5 through another drying tower 2 for further drying. Meanwhile, the adsorbent in one drying tower 2 is heated by electric heating or by circulating hot air to perform thermal regeneration. The specific working principle is well known in the prior art, and this technical solution only provides a brief description.

[0041] During the thermal regeneration process, the heat insulation layer 14 and the sound insulation layer 12, made of slag wool, also provide a certain degree of heat insulation, thereby reducing the heat dissipated from the drying tower 2 to the outside, thus improving the heat utilization rate and allowing more heat to be used for the regeneration of the adsorbent to improve the regeneration efficiency and indirectly reduce energy consumption. Furthermore, the presence of the sound insulation layer 12 reduces the outward propagation of abnormal noises caused by thermal expansion and contraction inside the drying tower 2 during regeneration, as well as the outward propagation of abnormal noises caused by friction and pressure changes of hydrogen gas passing through the adsorbent during adsorption. The first protective plate 11 and the second protective plate 13 support and connect the sound insulation layer 12 and the heat insulation layer 14, improving structural stability. During the thermal regeneration process, the temperature inside the drying tower 2 is monitored by the first temperature sensor 6 and the second temperature sensor 7, so that an electrical signal can be sent to the controller 3 to control the temperature of the electric heating or air heating, preventing the thermal regeneration temperature from becoming too high.

[0042] When the first protective plate 11, sound insulation layer 12, second protective plate 13, and heat insulation layer 14 are damaged, the workers can loosen the bolts 10, and then pull out the clamps 9 upwards or downwards to stop the restriction on the first protective plate 11 and the second protective plate 13. Finally, the workers can bend and disassemble the first protective plate 11, sound insulation layer 12, second protective plate 13, and heat insulation layer 14. During installation, the workers first bend the first protective plate 11, sound insulation layer 12, second protective plate 13, and heat insulation layer 14 and put them on the outside of the drying tower 2. Then, the workers push the clamps 9 upwards or downwards and put them on the outside of the support plate 8 and the first protective plate 11. Finally, the workers tighten the bolts 10 to complete the structural fastening and prevent the structure from loosening.
