Description

Technical Field

[0001] This utility model relates to the field of water electrolysis hydrogen production equipment, specifically a water replenishment device for AEM water electrolysis hydrogen production equipment. Background Technology

[0002] To achieve carbon emission reduction targets, vigorously developing hydrogen energy has become a global consensus. The application of hydrogen energy in energy storage, power generation, transportation, metallurgy, and chemical industries is gradually expanding. To realize the large-scale application of hydrogen energy, the development of water electrolysis hydrogen production systems and equipment is a crucial link. Currently, there are four main methods of water electrolysis hydrogen production: alkaline water electrolysis (AWE), proton exchange membrane water electrolysis (PEM), high-temperature solid oxide water electrolysis (SOE), and solid polymer anion exchange membrane water electrolysis (AEM). Among them, AEM water electrolysis hydrogen production has the characteristics of low cost, high efficiency, and strong controllability.

[0003] For example, patent CN118345402B discloses an integrated AEM water electrolysis hydrogen production device, relating to the field of water electrolysis hydrogen production technology. It includes a hydrogen production component, which comprises a base plate with two collection components on its top. In use, oxygen and hydrogen enter corresponding collection bottles through two collection pipes and two inlet pipes, respectively. During hydrogen collection, a temperature sensor detects the temperature, allowing operators to monitor the temperature on the control system display. The hydrogen then enters a cooler, where a cooling medium removes heat, thus cooling the hydrogen. Next, the hydrogen passes through a heat pipe; insulation material absorbs residual heat, which is then transferred to the outside via the heat pipe, further reducing the hydrogen temperature and preventing overheating during collection, which could affect storage and processing.

[0004] The aforementioned patent uses a water storage tank to supply water to the electrolyzer; however, the disadvantage of the aforementioned patent is that the water storage capacity of the integrated equipment's water storage tank is limited, while the hydrogen production equipment will rapidly consume a large amount of water, so the equipment needs to be replenished with water frequently.

[0005] Therefore, it is necessary to improve such a structure to overcome the above-mentioned defects. Utility Model Content

[0006] The purpose of this invention is to provide a water replenishment device for an AEM water electrolysis hydrogen production equipment to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A water replenishment device for an AEM water electrolysis hydrogen production equipment includes a water replenishment tank and a tank support for mounting the water replenishment tank. The tank support includes a bottom frame and a top frame, with the bottom frame and top frame fixedly connected at their four corners by first columns. The water replenishment tank is located on the left side of the first column, and a water supply pump is located on the right side of the first column. The water replenishment tank is fixedly installed on the top of the bottom frame, and similarly, the water supply pump is fixedly installed on the bottom of the bottom frame. Casters are also fixedly installed on the bottom of the tank support. A water supply hose is connected to the top of the water replenishment tank. The side of the water replenishment tank is connected to the inlet of the water supply pump via the first water replenishment hose, and a second water replenishment hose is connected to the outlet of the water supply pump.

[0009] Furthermore, casters are fixedly installed on the bottom of the bottom frame.

[0010] Furthermore, a drain outlet is provided on the bottom side of the water tank.

[0011] Furthermore, the water replenishment tank is also equipped with a primary filter, which includes a primary filter cylinder. The upper and lower ends of the primary filter cylinder are respectively connected to a first water inlet and a first water outlet; the top of the first water inlet is connected to a water supply hose.

[0012] Furthermore, the primary filter cylinder has a first filter chamber at one end near the first water inlet and a second filter chamber at one end near the first drain outlet. The first and second filter chambers are separated by a partition, and a through hole is provided at the center of the partition.

[0013] Furthermore, a PP filter element is installed in the first filter chamber, and an activated carbon filter element is installed in the second filter chamber.

[0014] Furthermore, the water supply tank is also equipped with a reverse osmosis filter, which includes a sleeve and a reverse osmosis filter element. The sleeve is fitted around the outside of the reverse osmosis filter element and is fixedly installed on the inner wall of the water supply tank by a flange. The reverse osmosis filter element includes a central tube with a reverse osmosis membrane wound around it. The central tube is fixedly installed inside the sleeve, and the end of the central tube passes through the water supply tank and is connected to the first water supply hose. Several seepage holes are opened on the side wall of the central tube.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Reasonable structural design

[0017] The layout is compact and rational: the partition columns place the water supply tank and water pump on the left and right sides respectively, making the layout of the device more compact, making full use of space, and facilitating installation and maintenance. At the same time, this layout also facilitates the connection and coordinated operation between various components, improving the overall operating efficiency of the system.

[0018] 2. Easy to move: The water tank support is equipped with casters at the bottom, especially at the four corners of the bottom frame, which facilitates the movement of the water supply device. In practical applications, the water supply device can be easily moved to a suitable location to supply water based on the location of the water electrolysis hydrogen production equipment, eliminating the need for large handling equipment, reducing labor intensity, and improving work efficiency.

[0019] 3. Improve water quality protection

[0020] The reverse osmosis filter operates under the negative pressure provided by the water supply pump, further improving the filtration effect. Water in the makeup water tank passes through the reverse osmosis membrane into the seepage holes, then into the central pipe, and finally flows into the first makeup water hose. This design effectively removes dissolved solids, heavy metal ions, and microorganisms from the water, providing a high-quality water source for the water electrolysis hydrogen production equipment and ensuring the stability and efficiency of the electrolysis process.

[0021] 4. Comprehensive functionality

[0022] Easy to refill: The top of the water tank is equipped with a water inlet hose for easy connection to the municipal water supply. When the water level in the tank drops, simply connect the hose to the municipal water source for quick refill, ensuring that the tank always has a sufficient water level.

[0023] Stable water supply: The water supply tank is connected to the inlet of the water supply pump via a first water supply hose, and the outlet of the water supply pump is connected to the water tank of the water electrolysis hydrogen production equipment via a second water supply hose. The water supply pump can provide stable pressure and flow rate, ensuring a continuous and stable supply of water to the water tank of the water electrolysis hydrogen production equipment, meeting the water demand of the electrolysis process.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of the utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0032] Please see Figure 1-3 A water replenishment device includes a water replenishment tank 1 and a water tank bracket 2 for mounting the water replenishment tank 1.

[0033] The water tank support 2 includes a bottom frame 201 and a top frame 202, and the bottom frame 201 and the top frame 202 are also fixedly connected at the four corners by a first column 203.

[0034] A water supply tank 1 is provided on the left side of the first column 203, and a water supply pump 3 is provided on the right side of the dividing column 204; the water supply tank 1 is fixedly installed on the top of the bottom frame 201, and similarly, the water supply pump 3 is fixedly installed on the bottom of the bottom frame 201.

[0035] In this design, casters 204 are also fixedly installed at the bottom of the water tank bracket 2 for easy movement;

[0036] Specifically, casters 204 are fixedly installed at the four corners of the bottom of the bottom frame 201;

[0037] In this scheme, a water supply hose 4 is connected to the top of the water supply tank 1. Since this scheme is used for AEM electrolysis of water to produce hydrogen, the AEM electrolysis of water to produce hydrogen process has lower requirements for water quality than the PEM process. Ordinary tap water or water containing a small amount of ions can be used for electrolysis.

[0038] Meanwhile, in this solution, the side of the water supply tank 1 is also connected to the inlet of the water supply pump 3 through the first water supply hose 301, and the outlet of the water supply pump 3 is also connected to the second water supply hose 302. The second water supply hose 302 is used to connect to the water tank of the water electrolysis hydrogen production equipment for water supply.

[0039] Meanwhile, in this solution, a drain outlet 101 is also provided on the bottom side of the water replenishment tank 1. A valve is provided on the drain outlet 101, and the drain outlet 101 is used to discharge the impurities accumulated in the water replenishment tank 1.

[0040] Meanwhile, in some embodiments of this solution, when the quality of municipal water is poor, such as... Figure 4-5 As shown, the water supply tank 1 is also equipped with a primary filter 5. The primary filter 5 includes a primary filter cylinder 501. The upper and lower ends of the primary filter cylinder 501 are respectively connected to a first water inlet 502 and a first water outlet 503. The top of the first water inlet 502 is connected to the water supply hose 4.

[0041] The primary filter cylinder 501 has a first filter chamber 510 at one end near the first water inlet 502 and a second filter chamber 520 at one end near the first drain outlet 503. The first filter chamber 510 and the second filter chamber 520 are separated by a partition 530, and a through hole is provided at the center of the partition 530.

[0042] A PP filter element 504 is installed in the first filter chamber 510. When the water passes through the PP filter element 504, the PP filter element 504 performs preliminary filtration of impurities.

[0043] The second filter chamber 520 is equipped with an activated carbon filter element 505. Water filtered by the PP filter element 504 in the first filter chamber 510 enters the second filter chamber 520 through the through holes on the partition 530, and is then filtered again by the activated carbon filter element 505 before finally flowing into the water supply tank 1.

[0044] In this utility model, the water supply hose 4 is connected to the municipal water supply. The water enters the primary filter 5 for pre-filtration. The water enters the first filter chamber 510 inside the primary filter 5. When the water passes through the PP filter element 504, the PP filter element 504 performs preliminary filtration of impurities in the water. Then, the water enters the second filter chamber 520 through the water inlet 28 and is filtered again through the activated carbon filter element 505.

[0045] like Figure 6-7As shown, the water supply tank 1 is also equipped with a reverse osmosis filter 6. The reverse osmosis filter 6 includes a sleeve 601 and a reverse osmosis filter element 602. The sleeve 601 is sleeved on the outside of the reverse osmosis filter element 602. The sleeve 601 is fixedly installed on the inner wall of the water supply tank 1 by a flange. The reverse osmosis filter element 602 includes a central tube 603. A reverse osmosis membrane 605 is wound on the central tube 603. The central tube 603 is fixedly installed inside the sleeve 601, and the end of the central tube 603 passes through the water supply tank 1 and communicates with the first water supply hose 301. Several seepage holes are opened on the side wall of the central tube 603.

[0046] Water in the water supply tank enters the seepage hole through the reverse osmosis membrane 605, then enters the central pipe 603, and finally flows into the first water supply hose 301. At the same time, the negative pressure provided by the water supply pump 3 improves the reverse osmosis filtration effect.

[0047] When in use, the water supply device can be moved to the water electrolysis hydrogen production point by means of caster 204, and then connected to the water tank of the water electrolysis hydrogen production equipment by means of the second water supply hose 302 for water supply;

[0048] When the water tank 1 needs to be replenished, the water hose 4 is connected to the municipal water supply. The water enters the primary filter 5 for pre-filtration. The water enters the first filter chamber 510 inside the primary filter 5. When it passes through the PP filter element 504, the PP filter element 504 performs preliminary filtration of impurities in the water. Then it enters the second filter chamber 520 through the water inlet 28 and is filtered again through the activated carbon filter element 505.

[0049] Meanwhile, when supplying water to the water tank of the water electrolysis hydrogen production equipment, the effluent can be further filtered through the reverse osmosis filter 6.
