It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] The following is combined with Figure 1-6 This invention describes a specific embodiment of an energy-saving power generation device, comprising:

[0038] Bracket 1,

[0039] The generator set 2 includes a hydrogen-oxygen fuel cell generator 21, which is mounted on the bracket 1. The principle of hydrogen-oxygen fuel cell power generation is to use hydrogen as fuel, oxygen as oxidant, and metal platinum as electrode material. In an acidic electrolyte solution, hydrogen loses electrons in the negative electrode chamber and decomposes into hydrogen ions. The hydrogen ions enter the positive electrode chamber through the proton exchange membrane. Electrons flow from the negative electrode to the positive electrode, realizing the conversion of chemical energy into electrical energy. The oxygen in the positive electrode chamber gains electrons and combines with hydrogen ions to form water molecules.

[0040] Hydrogen generator unit 3 is used to produce hydrogen gas to provide hydrogen fuel for generator set 2. Generator set 2 and hydrogen generator unit 3 are independently operating units. Hydrogen generator unit 3 produces and stores hydrogen gas to provide fuel for generator set 2 during operation. Hydrogen generator unit 3 is mounted on bracket 1 and located at the bottom of generator set 2. Hydrogen generator unit 3 includes a power supply panel 31 with a water inlet port 311. The water inlet port 311 is connected to an electrolyzer 33 via a pipeline. A hydrogen-water separator 34 is located on one side of the electrolyzer 33 for separating hydrogen gas from water vapor. The hydrogen-water separator 34 is connected to the electrolyzer 33. The hydrogen output end of 3 is connected, and the water inlet port 311 is used to connect to an external water source and to supply water to the electrolyzer 33. In the preparation of hydrogen, the electrolyzer 33 adopts the proton exchange membrane electrolysis (PEM) technology, using a polymer membrane with proton conductivity as the electrolyte. The diaphragm of the alkali-free electrolyzer 33 is mainly composed of a proton exchange membrane. Water is decomposed into oxygen, neutrons and protons at the anode. Oxygen is discharged from the anode, electrons flow to the cathode through the external circuit, and protons flow to the cathode through the proton exchange membrane. On the cathode side, two protons and electrons recombine to produce hydrogen. The produced hydrogen is then deoxygenated, heat exchanged and dried to finally achieve hydrogen storage and supply it to the generator set 2 as fuel for power generation.

[0041] The hydrogen storage module 4 is installed on one side of the hydrogen production unit 3 and is connected to the hydrogen output end of the hydrogen-water separator 34 through a pipeline for storing hydrogen. The hydrogen storage module 4 is connected to the hydrogen production pipeline to realize the storage of the prepared hydrogen. The hydrogen storage module 4 is not limited to hydrogen storage tanks or other hydrogen storage structures, as long as it can store the prepared hydrogen. No special limitations are made here.

[0042] The energy storage module 5 is installed between the hydrogen production unit 3 and the hydrogen storage module 4, and it is used to store the electrical energy generated in the generator set 2. The energy storage module 5 is a charging battery that stores the electrical energy generated by the reaction of the generator set 2.

[0043] Please refer to Figures 2-6 As shown, a water inlet port 311 is formed on the power supply panel 31, and the hydrogen production unit 3 further includes:

[0044] The first water pump 313 is fixedly installed on the bracket 1, and its input end is connected to the water inlet port 311. The first water pump 313 is used to extract and transport the cooling water returning from the water inlet port 311 or the energy storage device, so that the fluid is extracted and transported to the circulating water heat exchanger 32 for heat exchange. The working temperature of the PEM water electrolysis hydrogen production system should be about 60±5℃. By exchanging heat with the input fluid water, the temperature of the input fluid can be controlled according to the working temperature required of the electrolyzer 33, so as to ensure that the electrolyzer 33 operates at the optimal working temperature.

[0045] The circulating water heat exchanger 32 has its input end connected to the output end of the first water pump 313 via a pipeline, and its output end connected to the electrolytic cell 33.

[0046] Water tank 35 is fixedly installed on the bracket 1 and is connected to the fluid output end of the hydrogen-water separator 34 through a pipeline;

[0047] The second water pump 314 has its output end connected to the water tank 35 and its input end connected to the circulating water heat exchanger 32. The second water pump 314 is used to extract and transport cooling water from the water tank 35 to ensure the heat exchange required by the circulating water heat exchanger 32.

[0048] Please refer to Figures 3-6 As shown, the power supply panel 31 is provided with a nitrogen inlet 316, which is connected to the hydrogen-water separator 34. The nitrogen inlet 316 is used to introduce nitrogen into the hydrogen-water separator 34. In order to ensure the safe operation of the electrolytic cell 33, nitrogen is introduced into the electrolytic cell 33 during filling, draining, shutdown, or low-load operation. A nitrogen distribution head is provided near the head of the electrolytic cell 33. The pressure of the distribution head must be maintained within a set threshold. When filling with nitrogen, a temporary pipeline is connected to carry out the nitrogen filling operation to ensure the safety of the electrolytic cell 33.

[0049] Please refer to Figures 4-6 As shown, a deoxygenation tower 36, a hydrogen energy heat exchanger 37, and a drying tower 38 are sequentially connected along the hydrogen output pipeline of the hydrogen-water separator 34 from the hydrogen-water separator 34 to the hydrogen storage module 4. The deoxygenation tower 36, the hydrogen energy heat exchanger 37, and the drying tower 38 are all fixedly installed on the support 1, so that the hydrogen output from the hydrogen-water separator 34 passes through the deoxygenation tower 36 for deoxygenation, the hydrogen energy heat exchanger 37 for heat exchange to reduce the temperature of the output hydrogen, and the drying tower 38 to improve the dryness of the prepared hydrogen. The prepared hydrogen is finally stored in the hydrogen storage module 4 with optimal dryness and humidity to function during the operation of the generator set 2.

[0050] Please refer to Figures 3-5As shown, the power supply panel 31 is provided with a hydrogen detection port 315. The hydrogen detection port 315 is connected to the pipeline between the drying tower 38 and the hydrogen storage module 4 through a pipeline. The hydrogen detection port is used to detect the purity and related parameters of the prepared hydrogen.

[0051] Please refer to Figures 4-6 As shown, the power supply panel 31 is provided with a hydrogen exhaust port 312. The hydrogen exhaust port 312 is connected to the hydrogen output end of the hydrogen-water separator 34 and the hydrogen output end of the deoxygenation tower 36 through pipelines. When there is a fault at the front end of the equipment or the loss in the electrolysis cell 33 is large, the hydrogen output by the hydrogen-water separator 34 does not meet the preparation standard and can be directly discharged through the hydrogen exhaust port 312.

[0052] Please refer to Figures 4-6 As shown, the oxygen output end of the electrolytic cell 33 is connected to the water tank 35 through a pipeline. The oxygen produced by the electrolytic cell 33 is not usable in this device and can be directly discharged into the water tank 35 through the pipeline.

[0053] Please refer to Figure 5 As shown, the hydrogen-water separator 34 includes:

[0054] Tank 341, with a cavity formed inside it;

[0055] A gas-water separation baffle plate 342 is fixedly connected inside the tank 341. Multiple separation holes 343 are provided through the gas-water separation baffle plate 342. Gas and water are transported into the tank 341. The fluid is blocked by the gas-water separation baffle plate 342, and the gas can only pass through the separation holes 343 to be discharged, thus realizing the separation of gas and water.

[0056] A gas-water separation guide plate 344 is fixedly connected inside the tank body 341, and multiple plates are provided along the height direction of the tank body 341. The multiple gas-water separation guide plates 344 are staggered along the height direction of the tank body 341, and a gas flow channel 345 is formed between the multiple gas-water separation guide plates 344. Water vapor attached to the gas is blocked by the gas-water separation guide plates 344. By utilizing the gas flow channel 345 to increase the contact area between the gas and the gas-water separation guide plate 344, the separation of gas and water in the gas is improved.

[0057] Working principle of this utility model:

[0058] In the hydrogen production unit 3, the inlet end of the first water pump 313 is connected to the inlet port 311, drawing fluid water and transporting it to the circulating water heat exchanger 32 for heat exchange. The heat exchange temperature can be referenced to the operating temperature of the electrolyzer 33, which is preferably 60±5℃. After heat exchange, the fluid is transported into the electrolyzer 33. The electrolyzer 33 uses a polymer membrane with proton conductivity as the electrolyte. The diaphragm of the alkaline-free electrolyzer 33 is mainly composed of a proton exchange membrane. Water is decomposed into oxygen, neutrons, and protons at the anode. Oxygen is discharged from the anode, electrons flow to the cathode through the external circuit, and protons flow to the cathode through the proton exchange membrane. On the cathode side, two protons and electrons recombine to produce hydrogen gas, thus decomposing the fluid water under the action of the electrolyzer 33. Hydrogen and oxygen are produced in the electrolysis cell 33. The hydrogen is then sequentially transported to a hydrogen-water separator 34 for gas-water separation, a deoxygenation tower 36 for deoxygenation, and a hydrogen energy heat exchanger 37 for heat exchange. Finally, it is stored in the hydrogen storage module 4. The oxygen produced by the electrolysis cell 33 is directly transported to the water tank 35. The fluid produced by the hydrogen-water separator 34 is transported to the water tank 35 for storage. The rear end of the drying tower 38 is equipped with a hydrogen detection port 315 to detect the purity of the produced hydrogen. The water tank 35 can be used for heat exchange in the circulating water heat exchanger 32. The cooling water in the water tank 35 can be pumped by the second water pump 314 to the circulating water heat exchanger 32 to dissipate heat or to supply low-temperature fluid water to the electrolysis cell 33.

[0059] The hydrogen produced in the hydrogen generator unit 3 is stored in the hydrogen storage module 4. When the generator unit 2 is working, the hydrogen storage module 4 supplies hydrogen to the generator unit 2 as fuel to generate electricity, and the generated electricity is stored in the energy storage module 5.
