Description
Technical Field
[0001] The invention relates to the technical field of electrolysis, in particular to a device for mutual injection of electrolyte liquids for hydrogen production by electrolysis. Background Art
[0002] Renewable energy electrolysis of water to produce hydrogen is one of the most promising low-carbon, high-purity hydrogen production technology directions. However, the freshwater resources on which we depend for survival are extremely precious. Global freshwater resources are extremely limited, accounting for only about 3.5% of the total water volume, while seawater resources are abundant. How to use abundant seawater to achieve energy recycling becomes particularly important. In addition, hydrogen energy is a new generation of clean energy. Electrolysis of water to produce hydrogen is a green and efficient method. However, almost all systems currently use freshwater resources as electrolytes, which undoubtedly exacerbates the shortage of freshwater resources. If hydrogen is produced by direct electrolysis of seawater, it can produce high-purity freshwater as a fuel, which can achieve the dual purposes of seawater purification and hydrogen production at the same time. The development of a hydrogen economy is the only way for my country to transform to a renewable zero-carbon energy structure, and it is also the only way to achieve the goal of "carbon peak and carbon neutrality". However, in addition to high energy consumption, direct seawater electrolysis to produce hydrogen also faces additional huge challenges brought by the complex chemical environment of seawater, such as catalyst contamination and deactivation, anode chlorine oxidation side reactions and corrosion. To address the above difficulties, based on the principle of phase change migration of water molecules, instead of directly electrolyzing seawater, the water in the seawater is extracted into a concentrated electrolyte, and then hydrogen is obtained by electrolyzing the diluted electrolyte. This method of obtaining water is simple, efficient, and low-cost, and is suitable for large-scale application and construction, especially for coastal industrial areas, port terminal hydrogen refueling stations, offshore wind power hydrogen production and other occasions.
[0003] However, there is currently a lack of a machine that can quickly and accurately replace the electrolytes. If the electrolyte diluted by the water-drawing device is directly used for electrolytic hydrogen production, the pressure in the electrolytic cell will change rapidly, causing a large degree of interference with the electrolysis process, which is not conducive to the continuous operation of the electrolytic cell. Summary of the invention
[0004] In order to solve the problem in the above background technology that electrolyte replacement cannot be completed quickly and accurately, the purpose of the present invention is to provide a device for injecting electrolyte liquids into hydrogen production by electrolysis.

[0006] It also includes a first storage bin and a second storage bin. The first transfer bin is connected to the first storage bin and the second storage bin through a group of third delivery pipes. The corresponding third delivery pipes are equipped with a driving pump. A diverter column is rotatably installed in the first transfer bin, and a plurality of connecting holes are opened on the diverter column.
[0007] Preferably, two first delivery pipes are installed on the upper side of the concentrated electrolyte storage bin and the dilute electrolyte storage bin, each of which is installed with a first solenoid valve, and a fixed bracket is installed on the lower side of the concentrated electrolyte storage bin and the dilute electrolyte storage bin.

An exhaust pipe is installed on the mounting plate, and a second solenoid valve is installed on the exhaust pipe.
[0009] Preferably, an interface is also installed on the upper side of the installation disk, and the interface is electrically connected to the concentration sensor.
[0010] Preferably, a first electromagnetic shut-off valve and a first one-way valve are cooperatively installed on the second delivery pipe.
[0011] Preferably, it further comprises a second transfer bin, wherein the second transfer bin is connected to the concentrated electrolyte storage bin and the diluted electrolyte storage bin via two fourth delivery pipes;
[0012] The fourth delivery pipes are arranged in groups of two, a second electromagnetic shut-off valve and a second one-way valve are installed on one of the fourth delivery pipes, and a peristaltic pump is installed on the other fourth delivery pipe.
[0013] Preferably, a transfer chamber is rotatably installed in the second transfer warehouse, a partition plate is provided in the transfer chamber, the interior of the transfer chamber is divided into a first transfer chamber and a second transfer chamber by the partition plate, and a second drive motor is installed on the second transfer warehouse, and the second drive motor drives the transfer chamber to rotate.
[0014] Preferably, a quantitative air pump is installed on the lower side of the second transfer bin, and a cannula is installed inside the second transfer bin, and the cannula is coaxially arranged with the second transfer bin.
[0015] Preferably, a slot is provided on the lower side of the transfer chamber, the insert tube is inserted into the slot and connected thereto in a sliding fit, the partition plate is inlaid with a sliding tube, and a booster rod is slidably fitted in the sliding tube.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. The present invention designs a dual monitoring mechanism, in which a concentration sensor is embedded inside the first storage bin to monitor the electrolyte concentration of the flowing concentrated electrolyte in real time. This innovative method is parallel to the sensor directly installed in the concentrated electrolyte storage bin, which focuses on monitoring the electrolyte concentration of the relatively static concentrated electrolyte in the storage bin. Through these two complementary monitoring methods, the present invention not only realizes the full-scale grasp of the state of the concentrated electrolyte, but also effectively prevents the potential safety hazards caused by the drastic fluctuations in pressure and concentration, thereby significantly improving the stability and safety of the system.
[0019] 2. By using a quantitative air pump to quantitatively draw or release air into the cannula, the volume of the booster rod in the first transfer chamber can be changed, thereby changing the capacity of the single liquid injection, thereby affecting the volume ratio of the single liquid injection between the first transfer chamber and the second transfer chamber. When too much water in the concentrated electrolyte is electrolyzed, the quantitative air pump can be used to quantitatively release air into the cannula to move the booster rod toward the first transfer chamber, thereby reducing the volume of the first transfer chamber, thereby reducing the amount of concentrated electrolyte in the first transfer chamber that is exchanged by the quantitative single liquid injection of the dilute electrolyte in the second transfer chamber, thereby increasing the dilution effect of the concentrated electrolyte, effectively adapting to the errors that occur during the electrolysis of the electrolyte to produce hydrogen, so that the concentration of the electrolyte used for electrolysis is maintained within a certain range, thereby increasing the stability during electrolysis.

DETAILED DESCRIPTION
[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0033] Example 1
[0034] like Figure 1-Figure 7 As shown, the present embodiment provides a device for mutual injection of electrolyte liquids for hydrogen production by electrolysis, comprising a first transfer tank 101, a concentrated electrolyte storage tank 201 and a dilute electrolyte storage tank 202. The first transfer tank 101 is connected to the concentrated electrolyte storage tank 201 and the dilute electrolyte storage tank 202 via two second delivery pipes 301, and a first drive motor 102 is mounted on the first transfer tank 101.
[0035] It also includes a first storage bin 401 and a second storage bin 402. The first transfer bin 101 is connected to the first storage bin 401 and the second storage bin 402 through a set of third delivery pipes 407. A driving pump 408 is installed on the corresponding third delivery pipe 407. A transfer column 103 is rotatably installed in the first transfer bin 101. A plurality of connecting holes 104 are opened on the transfer column 103.
[0036] The present invention can control the rotation of the diverter column 103 through the first driving motor 102, so that the corresponding connecting hole 104 is connected to the corresponding second delivery pipe 301. In this embodiment, when in use, the present invention can be controlled in three states through the above method. In the first state, the liquid in the concentrated electrolyte storage bin 201 is transported to the first storage bin 401 through the corresponding second delivery pipe 301, and then flows into the other corresponding second delivery pipe 301 through the first storage bin 401 and flows into the dilute electrolyte storage bin 202 (refer to Figure 5 , on the left is the concentrated electrolyte storage bin 201, the concentrated electrolyte flows through the upper side pipeline of the concentrated electrolyte storage bin 201 and through the upper first storage bin 401 into the dilute electrolyte storage bin 202 in the shape of the letter "X", and the flow direction of the liquid is as follows: 1-5-8-7-6-3) according to the point reference in the figure, the liquid in the dilute electrolyte storage bin 202 is transported to the second storage bin 402 through the corresponding second delivery pipe 301, and then flows into another corresponding second delivery pipe 301 through the second storage bin 402 and flows into the concentrated electrolyte storage bin 201 (refer to Figure 5, the dilute electrolyte flows into the concentrated electrolyte storage bin 201 in the shape of a letter "X" through the upper side pipeline of the concentrated electrolyte storage bin 201 and through the first storage bin 401 below, and the flow direction of the liquid is as follows: 4-10-11-12-9-2) according to the point reference in the figure; the second state: the liquid in the concentrated electrolyte storage bin 201 flows through the corresponding second delivery pipe 301, and then flows back to the other second delivery pipe 301 of the concentrated electrolyte storage bin 201 through the through hole 510 on the transfer column 103, and finally flows back to the concentrated electrolyte storage bin 201 (refer to Figure 5 The concentrated electrolyte flows through the transfer column 103 and then flows back to the concentrated electrolyte storage bin 201. The flow direction of the liquid is as follows: 1-5-6-9-2). The corresponding liquid in the dilute electrolyte storage bin 202 flows through the corresponding second delivery pipe 301, and then flows back to the other second delivery pipe 301 of the dilute electrolyte storage bin 202 through the through hole 510 on the transfer column 103, and finally flows back to the concentrated electrolyte storage bin 201 (refer to Figure 5 , the dilute electrolyte flows in the transfer column 103 and then flows back to the dilute electrolyte storage bin 202. The flow direction of the liquid is as follows: 4-10-5-6-3). The third state: the passage from the dilute electrolyte storage bin 202 to the concentrated electrolyte storage bin 201 is closed, and only concentrated electrolyte can be quickly discharged into the dilute electrolyte storage bin 202. This situation is applicable when the pressure in the concentrated electrolyte storage bin 201 is dangerous (refer to Figure 5 The flow direction of the liquid is as follows: 1-5-6-3) according to the points in the figure.
[0037] In this embodiment, the first situation mentioned above is applicable to the situation where the pressure in the concentrated electrolyte storage bin 201 changes periodically. In this situation, the electrolyte concentration of the concentrated electrolyte can be monitored by the concentration sensor 410 in the first storage bin 401. This monitoring method is carried out simultaneously with the method of directly installing a sensor in the concentrated electrolyte storage bin 201 for monitoring. The sensor in the concentrated electrolyte storage bin 201 is used to monitor the electrolyte concentration of the relatively static concentrated electrolyte in the storage bin, and the concentration sensor 410 in the first storage bin 401 can be used to monitor the electrolyte concentration of the relatively flowing concentrated electrolyte in the first storage bin 401; the second situation mentioned above is applicable to the situation where the electrolyte concentration in the concentrated electrolyte is found to have changed over a large range in the first situation mentioned above, and this method can also be used to mix the concentrated electrolyte in the mixed concentrated electrolyte storage bin 201. The third situation mentioned above is used to quickly discharge the concentrated electrolyte in the concentrated electrolyte storage bin 201.
[0038] Two first delivery pipes 203 are installed on the upper side of the concentrated electrolyte storage bin 201 and the dilute electrolyte storage bin 202, and a first solenoid valve 204 is installed on each first delivery pipe 203. Fixed brackets 205 are installed on the lower side of the concentrated electrolyte storage bin 201 and the dilute electrolyte storage bin 202.
[0039] A mounting plate 403 is installed on the upper side of the first storage bin 401, and a monitoring ring 404 is installed on the mounting plate 403. The monitoring ring 404 extends into the first storage bin 401. The portion of the monitoring ring 404 located in the first storage bin 401 is mesh-shaped and has a plurality of concentration sensors 410 on its surface. An exhaust pipe 405 is installed on the mounting plate 403, and a second solenoid valve 406 is installed on the exhaust pipe 405.
[0040] An interface 409 is also installed on the upper side of the installation disk 403 , and the interface 409 is electrically connected to the concentration sensor 410 . A first electromagnetic shut-off valve 302 and a first one-way valve 303 are installed on the second delivery pipe 301 .
[0041] It should be noted that the present embodiment is applicable to the situation where the pressure in the concentrated electrolyte storage bin 201 is prone to fluctuate within a certain range. The electrolyte concentration of the concentrated electrolyte is monitored by the concentration sensor 410 in the first storage bin 401 in the present embodiment. This monitoring method is carried out simultaneously with the method of directly installing the sensor in the concentrated electrolyte storage bin 201 for monitoring. The sensor in the concentrated electrolyte storage bin 201 is used to monitor the electrolyte concentration of the relatively static concentrated electrolyte in the storage bin, and the concentration sensor 410 in the first storage bin 401 can be used to monitor the electrolyte concentration of the relatively flowing concentrated electrolyte in the first storage bin 401.
[0042] Example 2
[0043] like Figure 7-Figure 11 As shown, different from Example 1, this embodiment includes a second transfer tank 501, and the second transfer tank 501 is connected to the concentrated electrolyte storage tank 201 and the dilute electrolyte storage tank 202 through two fourth delivery pipes 601. The fourth delivery pipes 601 are grouped in pairs, and a second electromagnetic shut-off valve 602 and a second one-way valve 603 are installed on one fourth delivery pipe 601, and a peristaltic pump 502 is installed on the other fourth delivery pipe 601.
[0044] A transfer chamber 507 is rotatably installed in the second transfer warehouse 501, and a partition plate 511 is provided in the transfer chamber 507. The interior of the transfer chamber 507 is divided into a first transfer chamber 508 and a second transfer chamber 509 by the partition plate 511. A second drive motor 504 is installed on the second transfer warehouse 501, and the second drive motor 504 drives the transfer chamber 507 to rotate.
[0045] A quantitative air pump 512 is installed on the lower side of the second transfer chamber 501, and a cannula 513 is installed in the second transfer chamber 501. The cannula 513 is coaxially arranged with the second transfer chamber 501. A slot 516 is provided on the lower side of the transfer chamber 507. The cannula 513 is inserted into the slot 516 and slidably connected therewith. A sliding tube 514 is embedded and installed on the partition plate 511. A booster rod 515 is slidably fitted in the sliding tube 514. The quantitative air pump 512 is used to quantitatively draw air or deflate air into the cannula 513, so that the volume of the booster rod 515 in the first transfer chamber 508 can be changed. By changing the capacity of the single liquid injection, the volume ratio of the single liquid injection between the first transfer chamber 508 and the second transfer chamber 509 is affected. When too much water in the concentrated electrolyte is electrolyzed, the quantitative air pump 512 can be used to quantitatively release air into the insert tube 513 to move the booster rod 515 toward the first transfer chamber 508, thereby reducing the volume of the first transfer chamber 508, thereby reducing the amount of concentrated electrolyte in the first transfer chamber 508 that is exchanged by the quantitative single liquid injection of the light electrolyte in the second transfer chamber 509, thereby increasing the dilution effect of the concentrated electrolyte.
[0046] Four through holes 510 are provided on the transfer chamber 507. The four through holes 510 are arranged in groups of two. The two groups of through holes 510 are respectively connected to the first transfer chamber 508 and the second transfer chamber 509. Two pressure gauges 503 are installed on the second transfer chamber 501. The two pressure gauges 503 are arranged in cooperation with the first transfer chamber 508 and the second transfer chamber 509.
[0047] It should be further explained that when hydrogen is produced by electrolysis of electrolyte, the amount of hydrogen produced by electrolysis per unit time may be uncertain. In this case, the present embodiment can complete the conversion of single liquid injections. The quantitative air pump 512 can be used to quantitatively pump air or release air into the cannula 513, which can change the volume of the booster rod 515 in the first transfer chamber 508, thereby changing the capacity of the single liquid injection, thereby affecting the volume ratio of the single liquid injection between the first transfer chamber 508 and the second transfer chamber 509. When too much water in the concentrated electrolyte is electrolyzed, the quantitative air pump 512 can be used to quantitatively release air into the cannula 513 to move the booster rod 515 toward the first transfer chamber 508, thereby reducing the volume of the first transfer chamber 508, thereby improving the efficiency of the electrolysis. This makes the amount of diluted electrolyte in the second transfer chamber 509 that is injected into and exchanged with the concentrated electrolyte in the first transfer chamber 508 less, thereby increasing the dilution effect of the concentrated electrolyte. This can effectively adapt to errors that occur during hydrogen production by electrolyte electrolysis (when the concentration of the concentrated electrolyte exceeds a predetermined value per unit time, the boost rod 515 is controlled to extend outward to reduce the volume of the first transfer chamber 508, thereby reducing the ratio between the concentrated electrolyte and the diluted electrolyte; when the concentration of the corresponding concentrated electrolyte is less than a predetermined value per unit time, the boost rod 515 is controlled to contract inward to increase the volume of the first transfer chamber 508, thereby increasing the ratio between the concentrated electrolyte and the diluted electrolyte), thereby maintaining the concentration of the electrolyte used for electrolysis within a certain range, thereby increasing stability during electrolysis.
