Description

Technical Field

[0001] The utility model relates to the technical field of water electrolysis hydrogen production equipment, in particular to a water replenishing device without temperature difference fluctuation. Background Art

[0002] Water electrolysis is a process that uses electric current to decompose water into oxygen and hydrogen. It is an important industrial method for preparing hydrogen as a way to store and apply energy. In water electrolysis hydrogen production equipment, it is very important to ensure that water resources are sufficient and stable.

[0003] At present, the water replenishment system of the conventional electrolytic water hydrogen production equipment directly replenishes the deionized water at room temperature (about 20°C), while the operating temperature of the system is generally between (80 and 90°C). Deionized water is generally replenished to the electrolyte heat exchanger. After replenishing the deionized water, the electrolyte temperature in the device will drop by (6 to 10°C). When the electrolyte with reduced temperature is input into the electrolytic cell, the local temperature in the electrolytic cell will drop. Due to the uneven temperature inside the electrolytic cell, part of the current will increase and part of the current will decrease, resulting in a shortened electrode life in the part with increased current, accelerating the electrode aging speed, and thus reducing the overall life of the electrolytic cell. In the traditional method, it may be impossible to preheat the replenished deionized water in advance, resulting in the inability to raise the temperature of the replenished deionized water to the same temperature as the electrolyte at the inlet of the electrolytic cell in advance. In this way, replenishing the deionized water may cause the temperature of the electrolyte to change, which will also affect the abnormal change of the temperature inside the electrolytic cell, so that the electrolytic cell can never work and cannot reach the standard design operation state.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model can solve the problem that the life of the electrode part that causes the current increase will be shortened, the electrode aging speed is accelerated, and the overall life of the electrolytic cell is reduced by setting the input pipe, the tube array, the lower baffle plate and the fixed tube plate. The deionized water is transported to the interior of the deionized water heat exchanger through the input pipe. After entering the interior of the deionized water heat exchanger, the flow path and flow rate distribution of the deionized water are changed through the lower baffle plate and the upper baffle plate, and the normal temperature water transported from the water supply pipe to the interior of the tube array is heated, thereby increasing the surface area of ​​heat transfer and improving the heat exchange efficiency. The temperature of the deionized water after contact is changed. The temperature will slowly decrease, and part of it will be transported to the electrolyte tank through the drain pipe for recycling, so that the temperature of the deionized water inside the electrolyte tank is at the operating temperature, and part of it will flow into the mixing chamber through the delivery pipe and mix with the heated warm water to improve the temperature uniformity of the make-up water.

The life of the electrode will be shortened and the service life of the equipment will be effectively improved.

[0014] 2. The mixing chamber, water pipe and electrolyte heat exchanger can solve the problem that the temperature of the electrolyte may change after adding deionized water, which will affect the abnormal temperature change inside the electrolytic cell, making the electrolytic cell unable to reach the standard design operation state. After the electrolyte cell delivers deionized water to the deionized water heat exchanger through the input pipe, a part of the deionized water will be delivered to the mixing chamber through the delivery pipe, and then delivered to the mixing chamber together with the warm water added in the heated tubes to mix, so as to achieve the advance heating of the added warm water. After heating, the temperature of the mixed deionized water will drop again, and the mixed deionized water will be transferred to the electrolyte heat exchanger through the water pipe for heating, so that the mixed deionized water reaches the operating temperature of the equipment, and the deionized water is transported to the electrolytic cell through the pipeline for operation after heating. The used water will be transported to the electrolyte tank through the pipeline again for storage, thereby effectively heating and mixing the supplementary warm water in advance to improve the deionized water without causing the temperature change of the electrolyte, so that the electrolytic cell always works in the standard design operating state.

[0015] 3. During the operation of the equipment, various dirt may accumulate inside the heat exchanger, such as scale, sediment, biofilm, etc. These dirt will reduce the heat transfer efficiency of the heat exchanger, increase the heat conduction resistance, and increase the energy consumption of the system. The triple pipe is connected to the external water pipe and water tank, etc., and the water is transferred to the rotating pipe through the transfer pipe and the spray pipe. After being transferred to the rotating pipe, it will be sprayed from the nozzle through the pipe fittings at the bottom of the internal threaded pipe. When the water is sprayed, the internal threaded pipe is connected to the external threaded pipe. The pipe fittings of the external threaded pipe will drive the pipe fittings to rotate inside the external threaded pipe through the grooves opened inside the nozzle to improve the comprehensive cleaning of the deionized water heat exchanger. The dirt after cleaning will be collected through the bottom box at the bottom of the deionized water heat exchanger.

The other end of the array tube 6 is connected to the inside of the fixed tube sheet 4, and the internal supplementary warm water is heated by the deionized water outside through the array tube 6 and then discharged into the mixing chamber 15 to mix with the deionized water to increase the temperature of the supplementary warm water. The right side of the deionized water heat exchanger 1 is fixedly connected with a partition 9, and the left side wall of the partition 9 is fixedly connected to the middle of the right side wall of the fixed tube sheet 4. The partition 9 is set to separate the right side of the fixed tube sheet 4 into two areas. The right side of the interior of the water heat exchanger 1 is connected to a water supply pipe 10, the bottom wall of the interior of the deionized water heat exchanger 1 is fixedly connected to a lower baffle 11, and the top wall of the interior of the deionized water heat exchanger 1 is fixedly connected to an upper baffle 12. The interiors of the three lower baffles 11 and the two upper baffles 12 are connected to the outer side of the tube array 6 through the lower baffles 11 and the upper baffles 12. The turbulence of the water flow can be increased by increasing the contact area with the heat exchange medium, increasing the heat exchange efficiency, and supporting the outer side of the tube array 6. The right side of the interior of the deionized water heat exchanger 1 is connected to a drain pipe 14, and a portion of the deionized water is transferred to the electrolyte tank 31 through the drain pipe 14 for storage. A mixing chamber 15 is provided on the right side inside the deionized water heat exchanger 1 and on the bottom of the partition 9. A water pipe 16 is connected through the mixing chamber 15 and the right end of the deionized water heat exchanger 1. The mixing chamber 15 is separated by the partition 9, which helps to maintain a stable water flow to mix the deionized water and the supplementary warm water. After mixing, the mixed water is transferred to the next device through the water pipe 16. A baffle 17 is fixedly connected to the internal top wall of the deionized water heat exchanger 1, and the left and right sides of the bottom wall of the deionized water heat exchanger 1 are fixedly connected to the base 7. The top of the deionized water heat exchanger 1 is connected to an exhaust pipe 13, and the nitrogen and carbon dioxide inside the deionized water heat exchanger 1 are discharged through the exhaust pipe 13.

[0032] like Figure 1 - Fig.11 As shown, the deionized water heat exchanger 1 has spray pipes 18 fixedly connected to both upper and lower sides thereof. By fixing the two spray pipes 18 to the upper and lower sides of the deionized water heat exchanger 1, water is transferred to the spray head. The front and rear sides of the two spray pipes 18 are connected to the rotating pipes 19. The water inside the spray pipes 18 is transferred through the 19. The other ends of the two sets of rotating pipes 19 are connected to the internal threaded pipes 20, which are connected to the rotating pipes through the internal threaded pipes, which may be used to further guide the water and ensure its flow. The top rotating tube 19 is connected to the inside of the baffle 17, and the insides of the two groups of internal threaded tubes 20 are both threadedly connected to the external threaded tubes 21, and the insides of the two groups of external threaded tubes 21 are both provided with pipe fittings 22.

The bottoms of the two groups of pipe fittings 22 are fixedly connected to the insides of the two groups of nozzles 24. The insides of the two groups of nozzles 24 are both provided with grooves 25. When water is transferred to the nozzles 24, it will pass through the grooves 25. 5 to push the nozzle 24 and the pipe 22 to rotate inside the external threaded pipe 21, thereby effectively improving the cleaning area inside the deionized water heat exchanger 1. The left ends of the two spray pipes 18 are connected to the transfer pipe 26, and the insides of the two transfer pipes 26 are connected to the triple pipe 27. The triple pipe 27 is connected to the external water to transfer the water to the spray pipe 18 through the transfer pipe 26 on the other side of the triple pipe 27.

The dirt and impurities generated when the inside of the deionized water heat exchanger 1 is cleaned are collected by the bottom box 29, and the dirt and water are guided to the right by the guide plate 30, and the dirt and water are discharged through the sewage pipe 23 on the right.

[0033] like Figure 3As shown, it is a schematic diagram of the operation of the water replenishment system of the existing electrolytic water hydrogen production equipment. By adding warm water and deionized water to the electrolytic cell 32 for heating, the heated deionized water is transferred through the electrolyte heat exchanger 33 to improve the quality and purity of the product and ensure the normal operation of the electrolytic cell. By transferring deionized water to the electrolyte heat exchanger 33, the concentration of the electrolyte can be changed, the conductivity or pH can be reduced, so as to achieve more favorable electrolysis conditions. The water replenishment system directly replenishes deionized water at room temperature of about 20°C, and the operating temperature of the system is generally between 80 and 90°C. Deionized water is generally added to the electrolyte heat exchanger. After adding deionized water, the electrolyte temperature in the device will drop by 6 to 10°C. When the electrolyte with reduced temperature is input into the electrolytic cell, the local temperature in the electrolytic cell will be reduced. Due to the uneven temperature inside the electrolytic cell, part of the current will increase and part of the current will decrease, resulting in a shortened electrode life in the part with increased current, which accelerates the electrode aging rate and reduces the overall life of the electrolytic cell.

[0034] like Figure 1 - Figure 4 As shown, the right end of the deionized water heat exchanger 1 is connected to an electrolytic cell 32 through a water delivery pipe 16. The mixed deionized water is heated by the electrolytic cell 32. The temperature of the mixed deionized water will drop to 50-60°C. The other end of the electrolytic cell 32 is connected to an electrolyte heat exchanger 33 through a pipeline. The heated deionized water is transferred to the electrolyte heat exchanger 33 through the pipeline for operation. The electrolyte heat exchanger 33 is connected to an electrolyte tank 31 through a pipeline. The bottom of the electrolyte tank 31 is connected to the left end of the water supply pipe 10 through an input pipe 2. The bottom of the deionized water heat exchanger 1 is connected to the electrolyte tank 31 through a drain pipe 14. After the deionized water is transferred to the electrolyte tank 31 through the electrolyte heat exchanger 33, part of the deionized water will be transferred to the deionized water heat exchanger 1 through the input pipe 2 after a period of time to heat the supplementary warm water, and then it will be divided into two parts again. One part will transfer the deionized water back to the electrolyte tank 31 through the drain pipe 14, and the other part will be mixed with the supplementary warm water through the delivery pipe 8 and transferred to the electrolytic tank 32 for further heating, thereby achieving a circulation effect, improving the cooling of the deionized water, and evenly heating and mixing the supplementary warm water, so as to reduce the shortening of the electrode life of the current increase part and effectively improve the service life of the equipment.

[0035] It should be noted that the utility model is a water replenishment device without temperature difference fluctuation. First, the deionized water stored in the electrolyte tank 31 is transferred to the deionized water heat exchanger 1 through the input pipe 2. The flow path and flow velocity distribution of the deionized water fluid will be changed through the lower baffle 11 and the upper baffle 12 inside the deionized water heat exchanger 1. The tubes 6 are supported by the array tubes 6 connected through the lower baffle 11 and the upper baffle 12. After the deionized water is transferred to the interior of the deionized water heat exchanger 1, the water replenishment pipe 10 on the right end of the deionized water heat exchanger 1 transports the supplementary warm water to the top wall of the partition 9 for storage and connects the connecting block 5 and the tubes 6 inside the fixed tube sheet 4, so that the warm water flows into the tubes 6, and the fixed tube sheet 4 intercepts it. To prevent the deionized water from flowing into the right part, the warm water inside the tube array 6 will heat the internal warm water through the deionized water on the outer surface of the tube array 6. During heating, the temperature of the warm water will slowly rise, and the deionized water will slowly reduce the temperature. The deionized water finally reaches 74-78°C. A part of the cooled deionized water will be transported to the electrolyte tank 31 through the drain pipe 14 at the bottom right of the deionized water heat exchanger 1, and the other part will flow into the mixing chamber 15 through the delivery pipe 8 at the bottom of the fixed tube plate 4. While flowing in, the heated warm water inside the tube array 6 will pass through the other end of the tube array 6 through the top of the delivery pipe 8 to transfer the warm water to the mixing chamber 15. After reaching the mixing chamber 15, the deionized water and the warm water will be mixed to improve the problem of replenishing warm water and achieve the effect of preheating in advance.

[0036] Deionized water is transported to the deionized water heat exchanger 1 through the input pipe 2, so that the exhaust gas inside the electrolyte tank 31 enters the deionized water heat exchanger 1. The exhaust gas contains waste heat. When the warm water is heated, the waste heat will heat the internal tube array 6 when it is discharged through the exhaust pipe 13, thereby increasing the speed at which the warm water is heated.

[0037] After the supplemented warm water and part of the deionized water are mixed in the mixing chamber 15 through the deionized water heat exchanger 1, the mixed warm water will be cooled down again and transferred to the electrolyte heat exchanger 33 through the water pipe 16 to heat the warm water so that the mixed deionized water reaches the operating temperature of the equipment. The heated water will be transported to the electrolytic cell 32 through the pipe on the other end of the electrolyte heat exchanger 33 for operation. The deionized water after operation will be discharged into the electrolyte cell 31 through the pipe on the other side of the electrolytic cell 32 for storage. The stored water will enter the deionized water heat exchanger 1 through the input pipe 2 again to heat and mix the supplemented warm water.

[0038] When it is necessary to clean the inside of the deionized water heat exchanger 1, the triple pipe 27 is connected to the external water pipe and water tank, etc., and the water is transferred to the rotating tube 19 through the transfer tube 26 and the spray pipe 18. After being transferred to the rotating tube 19, the water is sprayed out from the nozzle 24 through the pipe fitting 22 at the bottom of the internal threaded tube 20. When the water is sprayed, the internal threaded tube 20 is connected to the external threaded tube 21, and the pipe fitting 22 of the external threaded tube 21 drives the pipe fitting 22 to rotate inside the external threaded tube 21 through the groove 25 opened inside the nozzle 24, so as to improve the comprehensive cleaning of the inside of the deionized water heat exchanger 1. The dirt after cleaning will be collected through the bottom box 29 at the bottom of the deionized water heat exchanger 1, and the dirt will be diverted to the right middle drain pipe 23 through the guide plate 30 inside the bottom box 29 for discharge, and the valve 28 is used to switch to control the flow rate and amount of water.
