Description

Technical Field

[0001] This invention relates to the field of electrolyte hydrogen production equipment technology, and in particular to a rapid heat dissipation electrolyzer and hydrogen production equipment. Background Technology

[0002] Hydrogen has a high calorific value, which is three times that of gasoline, 3.9 times that of alcohol, and 4.5 times that of coke. Furthermore, the combustion product of hydrogen is water, making it one of the cleanest energy sources in the world. As a highly efficient and environmentally friendly energy source, hydrogen energy has received widespread attention worldwide. Therefore, large-scale, low-cost hydrogen production is a key focus in the development and utilization of hydrogen energy.

[0003] Electrolysis of water is currently a widely used method for hydrogen production, producing hydrogen and oxygen through the electrolysis of water. Inside the electrolyzer, the anode and cathode plates generate significant heat when energized, raising the temperature of the electrolyte. Poor overall heat dissipation within the electrolyzer significantly impacts hydrogen production efficiency. Current methods for improving heat dissipation involve increasing the overall volume of the electrolyzer, but this increases manufacturing costs, significantly raises energy consumption, and makes production and use inconvenient. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the purpose of this invention is to provide a fast heat dissipation electrolyzer and hydrogen production equipment to solve the problem of poor heat dissipation in the process of producing hydrogen by electrolyzing water in the prior art.

[0005] To achieve the above and other related objectives, the present invention provides a rapid heat dissipation electrolytic cell, comprising:

[0006] The tank has a cavity with an opening at the top. A diaphragm is provided in the middle of the tank, which divides the cavity into a cathode cavity and an anode cavity. A cathode electrode is provided in the cathode cavity, and an anode electrode is provided in the anode cavity. A cathode electrode post electrically connected to the cathode plate and an anode electrode post electrically connected to the anode plate are embedded outside the tank.

[0007] A cover plate is used to fasten to the upper end of the tank and seal the receiving cavity. The cover plate has an anode plate condensation section extending into the anode cavity and a cathode plate condensation section extending into the cathode cavity on the side facing the receiving cavity. The anode plate condensation section is arranged around the anode plate, and the cathode plate condensation section is arranged around the cathode plate.

[0008] The cover plate is provided with an anode condenser inlet pipe and an anode condenser outlet pipe on the side away from the receiving cavity, which are connected to the anode plate condenser section, as well as a cathode condenser inlet pipe and a cathode condenser outlet pipe on the side connected to the cathode plate condenser section.

[0009] Optionally, both the anode plate condensation section and the cathode plate condensation section include multiple sets of spiral condenser tubes, and the spiral condenser tubes in the same set are connected.

[0010] Optionally, the tank body is provided with an inner shell, and the space between the inner shell and the tank body is a condensation chamber. The inner shell is provided with a condensation inlet pipe and a condensation outlet pipe.

[0011] Optionally, the inner shell is provided with an outer shell, and a heat dissipation cavity is formed between the outer shell and the inner shell. The outer shell is provided with an air inlet and an air outlet connected to the heat dissipation cavity, and an air inlet pump is provided at the air inlet.

[0012] Optionally, the inner shell is made of a thermally conductive material, and the outer shell is made of a thermally insulating material.

[0013] Optionally, both the air outlet and the air inlet are provided with sealing caps, which close the air outlet and the air inlet to form a heat dissipation cavity into a heat preservation cavity.

[0014] Optionally, the sealing cover is provided with a sliding cavity frame, and the sealing cover is slidably disposed along the sliding cavity frame. An electromagnet is provided above the sliding cavity frame, and a magnetic strip is provided on one side of the sealing cover. When the electromagnet is energized, it attracts the magnetic strip, causing the sealing cover to slide upward and open the air outlet or the air inlet. When the electromagnet is de-energized, the sealing cover slides downward along the sliding cavity frame under the action of gravity to seal the air outlet or the air inlet.

[0015] Optionally, the electromagnet is connected in series with the circuit of the air pump, and the energization of the air pump and the energization / de-energization of the electromagnet are synchronized.

[0016] Optionally, the air outlet and the air inlet are both located on the end faces of both sides of the outer casing, and the condensate inlet pipe and the condensate outlet pipe are both located on the end faces of both sides of the inner casing and extend outside the outer casing.

[0017] Accordingly, the present invention also provides a hydrogen production apparatus, comprising:

[0018] As described above, this invention provides cathode and anode plate condensation sections on the cover plate for cooling the cathode and anode plates. The cathode plate condensation section dissipates heat generated by the cathode plate during electrolysis by cooling its surrounding area, and the anode plate condensation section dissipates heat generated by the anode plate during electrolysis by cooling its surrounding area. Since the condensation sections are located around the plates, they can effectively remove heat generated during use through condensate, resulting in better heat dissipation for the electrolytic cell. Furthermore, the condensation sections in this design do not interfere with the use of the electrolytic cell. Compared to existing technologies, this design, by providing condensation sections on the cover plate to create a cooling zone around the plates, effectively dissipates heat generated during use without interfering with the operation of the electrolytic cell.

[0031] Before describing the embodiments of the present invention in detail, the application environment of the present invention will be described first. The technology of the present invention is mainly applied to the process of hydrogen production from electrolytes, especially to the process of hydrogen production from electrolyzers. The present invention solves the technical problem of poor heat dissipation affecting the hydrogen production efficiency in the process of hydrogen production from electrolytes.

[0032] Figure 1 A schematic diagram of a hydrogen production apparatus as an example of the present invention is shown below. Figure 1This invention provides a hydrogen production device, which includes a condensate tank 500 and a rapid heat dissipation electrolytic cell 100. The condensate tank 500 is used to provide condensate, and the condensate tank 500 is provided with a main water supply pipe 501 and a main water return pipe 502. The rapid heat dissipation electrolytic cell 100 is a rapid heat dissipation electrolytic cell 100 in any of the following embodiments. The cathode condensate inlet pipe, the anode condensate inlet pipe, and the condensate inlet pipe provided on the electrolytic cell 100 are all connected to the main water supply pipe 501. The cathode condensate outlet pipe, the anode condensate outlet pipe, and the condensate outlet pipe provided on the electrolytic cell 100 are all connected to the main water supply pipe 501.

[0033] The specific structure of the rapid heat dissipation electrolytic cell 100 in this invention is described in conjunction with the following reference: Figure 2 and Figure 4 The rapid heat dissipation electrolytic cell 100 includes:

[0034] The tank has a receiving cavity 120 with an opening at the top. A diaphragm 110 is provided in the middle of the tank, which divides the receiving cavity 120 into a cathode cavity 122 and an anode cavity 121. A cathode electrode is provided in the cathode cavity 122, and an anode electrode is provided in the anode cavity 121. A cathode electrode post 151 electrically connected to a cathode plate 150 and an anode electrode post 131 electrically connected to an anode plate 130 are embedded outside the tank.

[0035] A cover plate 101 is used to fasten to the upper end of the tank and seal the receiving cavity 120. The cover plate 101 has an anode plate condensation part 140 extending into the anode cavity 121 and a cathode plate condensation part 160 extending into the cathode cavity 122 on the side facing the receiving cavity 120. The anode plate condensation part 140 is arranged around the anode plate 130, and the cathode plate condensation part 160 is arranged around the cathode plate 150.

[0036] The cover plate 101 has an anode condenser inlet pipe and an anode condenser outlet pipe that communicate with the anode plate condenser 140, and a cathode condenser inlet pipe and a cathode condenser outlet pipe that communicate with the cathode plate condenser 160, on the side away from the receiving cavity 120.

[0037] In the specific implementation process, both the anode plate condensation section 140 and the cathode plate condensation section 160 are equipped with condensate pipes surrounding the plates. For example, the condensate pipes can be spirally or irregularly curved around the plates. The condensate pipes are positioned around the plates to effectively remove the heat generated during operation, thus achieving better heat dissipation for the electrolytic cell 100. Furthermore, the arrangement of the condensation sections in this design does not affect the operation of the electrolytic cell 100.

[0038] In some embodiments, both the anode plate condensation section 140 and the cathode plate condensation section 160 include multiple sets of spiral condenser tubes, and the spiral condenser tubes in the same set are connected. Specifically, for example, Figure 4 As shown, multiple sets of spiral condenser tubes are arranged around the electrode plate. The spiral condenser tubes can be arranged in pairs, and three or four sets can be arranged around the electrode plate. In each set of spiral condenser tubes, one is connected to the water inlet pipe of the condenser section, and the other is connected to the water outlet pipe of the condenser section. This allows for quick replacement of the condensate in the spiral condenser tubes. At the same time, the contact area between the spiral condenser tubes and the electrode plate is large, which can effectively improve the heat dissipation effect.

[0039] In some embodiments, the tank body is provided with an inner shell 200, and a condensation chamber 201 is formed between the inner shell 200 and the tank body. The inner shell 200 is provided with a condensate inlet pipe 202 and a condensate outlet pipe 203. Specifically, for example, Figure 4 As shown, the inner shell 200 encloses the outside of the tank body, forming a condensation cavity 201, including the tank body, between the inner shell 200 and the tank body. Cooling water is introduced into the condensation cavity 201 to dissipate heat from the entire electrolytic cell 100. In a specific implementation, the surface of the tank body can be provided with protruding structures to accommodate the recesses inside the cavity 120, thereby increasing the area between the cavity 201 and the surface of the tank body, further improving the heat dissipation effect on the electrolytic cell 100.

[0040] In some embodiments, an outer shell 300 is provided outside the inner shell 200, and a heat dissipation cavity is formed between the outer shell 300 and the inner shell 200. The outer shell 300 is provided with an air inlet 302 and an air outlet 304 connected to the heat dissipation cavity, and an air inlet pump 303 is provided at the air inlet 302. Specifically, for example, Figure 4 As shown, the outer shell 300 is wrapped around the inner shell 200, and the gap between the outer shell 300 and the inner shell 200 forms a heat dissipation cavity. Air is continuously pumped into the heat dissipation cavity by the air pump 303, so that the air can circulate in the heat dissipation cavity, which can effectively remove the heat on the inner shell 200 and further improve the heat dissipation effect of the electrolytic cell 100.

[0041] In some embodiments, the inner shell 200 is made of a thermally conductive material, and the outer shell 300 is made of a thermally insulating material. In specific implementations, the inner shell 200 forms a condensation chamber 201, allowing condensate to carry away heat. During the flow of condensate, some heat is conducted onto the inner shell 200, and the thermally conductive material helps dissipate this heat. The outer shell 300 forms a heat dissipation chamber, which is air-cooled. The thermally insulating material supporting the outer shell 300 helps to insulate heat, facilitating the air to carry away the heat from the inner shell 200.

[0042] In some embodiments, both the air outlet 304 and the air inlet 302 are provided with sealing caps 401. The sealing caps 401 close the air outlet 304 and the air inlet 302, thus forming a heat dissipation cavity into an insulation cavity. Specifically, for example... Figure 2 and Figure 3 As shown, sealing covers 401 are installed at both the air inlet 302 and the air outlet 304. If a power outage occurs during the use of the electrolytic cell 100, it is necessary to maintain the internal temperature of the electrolytic cell 100 so that the various chemical reactions in the motor tank can be stopped slowly. At this time, the sealing covers 401 can be used to close the air inlet 302 and the air outlet 304, shut down the condenser and the condenser chamber 201, and perform heat preservation treatment on the electrolytic cell 100.

[0043] In some embodiments, a sliding cavity frame 400 is provided at the sealing cover 401, and the sealing cover 401 is slidably disposed along the sliding cavity frame 400. An electromagnet 402 is provided above the sliding cavity frame 400, and a magnetic strip 403 is provided on one side of the sealing cover 401. When the electromagnet 402 is energized, it attracts the magnetic strip 403, causing the sealing cover 401 to slide upward and open the air outlet 304 or the air inlet 302. When the electromagnet 402 is de-energized, the sealing cover 401 slides downward along the sliding cavity frame 400 under the action of gravity to seal the air outlet 304 or the air inlet 302. Specifically, for example, Figure 2 and Figure 3 As shown, sliding cavity frames 400 are provided on both sides of the air outlet 304 and the air inlet 302. A sliding groove is provided within the sliding cavity frame 400. The two ends of the sealing cover 401 are slidably disposed within the sliding groove. The lower end of the sliding groove is located at the lower end of the air outlet 304 or the air inlet 302, and a limiting part is provided at the lower end of the sliding groove to restrict the sliding of the sealing cover 401. During use, the sealing cover 401 can be controlled by switching the electromagnet 402 on and off. When the electrolytic cell 100 is normally energized for electrolysis, the electromagnet 402 attracts the magnetic strip 403, causing the sealing cover 401 to move upwards along the sliding groove, opening the air outlet 304 and the air inlet 302. When the electrolytic cell 100 stops working and the electromagnet 402 is de-energized, the sealing cover 401 slides downwards along the sliding groove under its own weight, sealing the air outlet 304 and the air inlet 302, thus providing heat preservation for the interior of the electrolytic cell 100.

[0044] In some embodiments, the electromagnet 402 is connected in series with the air pump 303, and the energization of the air pump 303 and the electromagnet 402 are synchronized. When the electrolytic cell 100 is not in use, the air pump 303 can stop working and needs to be de-energized. At this time, the electromagnet 402 can be de-energized simultaneously so that the sealing cover 401 can seal the air outlet 304 and the air inlet 302.

[0045] In some embodiments, the air outlet 304 and the air inlet 302 are both located on the end faces of both sides of the outer casing 300, and the condensate inlet pipe 202 and the condensate outlet pipe 203 are both located on the end faces of both sides of the inner casing 200 and extend outside the outer casing 300. Specifically, for example, Figure 2 and Figure 4 As shown, the air outlet 304 and air inlet 302 are respectively set at both ends of the outer shell 300, which improves the ventilation effect of the heat dissipation cavity, that is, the heat dissipation effect is better. The condensate inlet pipe 202 and condensate outlet pipe 203 are both located on the end faces of both sides of the inner shell 200 and extend out of the outer shell 300 to facilitate the flow of condensate.

[0046] In the specific implementation process, for example, Figure 4 As shown, to facilitate energizing the anode plate 130 and cathode plate 150, a support column is provided at the bottom of the outer casing 300. The anode column 131 and cathode column 151 are located at the bottom of the electrolytic cell 100 and pass through the inner casing 200 and the outer casing 300, respectively, and are located on the surface of the outer casing 300. An anode vent pipe 132 and a cathode vent pipe 152 are also provided on the cover plate 101 to facilitate the collection of gases electrolyzed during the use of the electrolytic cell 100.

[0047] The above embodiments are merely illustrative of the principles and effects of the present invention and are not intended to limit the invention. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in the present invention should still be covered by the claims of the present invention.
