Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen energy, hydrogen compressors and electric motors, and specifically relates to a dual-system hydrogen compression system of electric drive and hydrogen drive. Background Art

[0002] With the growing demand for clean energy, photovoltaic power generation, as an important renewable energy source, is becoming increasingly widely used. However, the intermittent and unstable nature of photovoltaic power generation poses challenges to the stable operation of power systems. To address this issue, an effective approach is to use the electricity generated by photovoltaic power generation to produce hydrogen through water electrolysis. The resulting hydrogen is then pressurized and transported through a hydrogen compressor. Hydrogen compressors play a key role in this process. Hydrogen compressors are specialized equipment used to compress hydrogen and are widely used in all aspects of hydrogen energy production, storage, and utilization. Traditional hydrogen compressors typically use mechanical drives, which are subject to low efficiency, high noise, and high vibration. This not only affects energy efficiency but can also have adverse effects on the surrounding environment.

[0003] Currently, most photovoltaic water electrolysis hydrogen production projects use traditional electric compressors. Electric compressors use an electric motor as the driving source, compressing gas through a rotor and vortex blades. Compared to traditional mechanical drive methods, electric compressors offer the advantages of higher efficiency, lower noise, and lower vibration. Hydrogen-driven compressors use hydrogen itself as the driving source, with the expanding hydrogen pushing the piston or rotor to achieve compression, resulting in high efficiency, low noise, and low vibration.

[0004] A search found that publication number CN118004964A discloses a hydrogen compression system, which includes: a heat pump part, including a heat pump pipeline configured to circulate a refrigerant; a hydrogen compression part, configured to compress hydrogen by repeatedly being heated and cooled; a first circulation pipeline, which is connected to the heat pump pipeline while passing through the hydrogen compression part and is configured to circulate the refrigerant introduced from the heat pump pipeline; a second circulation pipeline, which is arranged to pass through the hydrogen compression part and is configured to circulate a cooling fluid; and a cooling unit, which is arranged in the second circulation pipeline and is configured to cool the cooling fluid, wherein the hydrogen compression part is heated by the refrigerant or cooled by the cooling fluid, thereby minimizing power consumption and improving energy efficiency.

[0005] Existing electric compressors present several problems during use. First, they consume large amounts of electricity, which not only increases operating costs but also puts pressure on the power grid. Second, due to insufficient power supply at night, electric compressors operate inefficiently at night, which affects hydrogen production and transmission efficiency. In addition, traditional electric compressors generate noise and vibration during operation, which pollutes the environment. Electric compressors have certain limitations in compression ratio and flow rate. The design and manufacturing process of hydrogen compressors is relatively complex and the cost is relatively high. Therefore, there is an urgent need for a new hydrogen compressor to solve the above problems. Utility Model Content

[0006] In order to overcome the problem that existing electric-driven compressors consume a lot of electricity during use, increase operating costs, and put pressure on the power grid, at the same time, electric-driven compressors also generate noise and vibration during operation, causing environmental pollution, the utility model provides a dual-system hydrogen compression system of electric drive and hydrogen drive. In the case of insufficient power, the hydrogen generated by the electrolyzer enters the hydrogen turbine to provide driving energy, which reduces the consumption of electricity, reduces operating costs, effectively reduces the noise and vibration generated by the compressor during operation, reduces pollution to the environment, and increases the service life of the equipment.

[0041] Preferably, the permanent magnet synchronous motor 11 is fixedly connected to the inner lower surface of the cabinet 6 , and the bottom of the hydrogen turbine 7 is fixedly connected to the top of the fixing plate 10 .

[0042] Preferably, the outer side wall of one end of the transmission rod 16 is rotatably connected to the inner side wall of one end of the rotating drum 14 , and the inner side walls of the two rotating wheels 9 are rotatably connected to the outer side walls of the rotating rod 8 and the outer side walls of the transmission rod 16 respectively.

[0047] Preferably, the electrolyte is an alkaline electrolyte.

[0048] The electrolytic cell 3 in the present invention produces hydrogen using an alkaline electrolytic cell. The basic principle of alkaline water electrolysis is that, under the action of direct current, water molecules undergo oxidation and reduction reactions at the two electrodes of the electrolytic cell. In the electrolytic cell, water molecules are reduced at the cathode, generating hydrogen and hydroxide ions (Hydrogen Evolution Reaction, HER). The generated hydroxide ions then pass through the physical diaphragm to the anode, where they lose electrons and evolve oxygen, generating oxygen and water. In industry, 30% by mass KOH solution or 26% by mass NaOH solution is commonly used as the electrolyte for electrolytic cells.

[0049] In this utility model, photovoltaic-generated DC electricity is directly transmitted via lines to electrolyzer 3. Photovoltaic hydrogen production is essentially solar hydrogen production. Its basic principle is to first generate electricity using solar photovoltaics, then electrolyze water to produce hydrogen and oxygen.

When the drum 14 rotates, the left block 18 and the transmission rod 16 are rotated through the left ratchet groove 21. The rotation of the transmission rod 16 will rotate with the right block 18. The hydrogen turbine 7 is not working, the rotating rod 8, the upper wheel 9, the belt 12 and the lower wheel 9 cannot rotate. In this way, the right ratchet groove 21 will squeeze the right block 18 into the inside of the storage hole 19, and the lower wheel 9 will not affect the rotation of the transmission rod 16. When the hydrogen turbine 7 is working and the permanent magnet synchronous motor 11 stops, the drum 14 will not affect the rotation of the transmission rod 16.

The wind power generation device 1 and the photovoltaic power generation device 2 generate electricity, and the electricity drives the permanent magnet synchronous motor 11. The permanent magnet synchronous motor 11 rotates the rotating drum 14 and the transmission rod 16. The transmission rod 16 rotates the crankshaft of the hydrogen compressor to make the hydrogen compressor work. At the same time, electricity will also enter the electrolyzer 3, and the electrolyzer 3 will produce hydrogen. The hydrogen compressor compresses the hydrogen produced by the electrolyzer 3. If the output power of the wind power generation device 1 and the photovoltaic power generation device 2 decreases, the control device 5 starts the hydrogen turbine 7 and shuts down the permanent magnet synchronous motor 11. The hydrogen produced by the electrolyzer 3 enters the hydrogen turbine 7 to provide driving energy. The hydrogen turbine 7 rotates the rotating rod 8 and the upper runner 9. The upper runner 9 rotates with the lower runner 9 and the transmission rod 16 through the belt 12.

[0055] The utility model reduces the consumption of electric energy, lowers the operating cost, and alleviates the pressure on the power grid; the utility model avoids the problem of low working efficiency caused by insufficient power supply, thereby improving the production and transmission efficiency of hydrogen.

[0056] The utility model effectively reduces the noise and vibration generated by the compressor during operation, reduces pollution to the environment, and increases the service life of the equipment.
