[0029] Example

[0030] like Figure 1-6 As shown, a solar power generation system proposed by the utility model includes a solar cell panel 2 for absorbing sunlight and converting it into electrical energy, and also includes: a reaction mechanism arranged on the solar cell panel 2 for converting the electricity generated by the solar cell panel 2 into ammonia water; and a fertilizer mechanism installed on the reaction mechanism so that the ammonia water is made into fertilizer or directly used for fertilizer.

[0031] Further, the reaction mechanism includes a second filter 12, an air compressor 13, an ammonia electrolytic cell 14, a cathode 15 and an anode 16. The air compressor 13 is a device for compressing air into high-pressure gas. They are widely used in industrial production, manufacturing, construction and other fields. Air compressors usually pressurize the air through devices such as pistons, screws or centrifugal compressors, converting low-pressure air into high-pressure gas. The solar panel 2 is provided with an energy conversion module 3 for converting electrical energy into voltage and current. The energy conversion module 3 is a key component for converting solar energy into electrical energy. It consists of a series of solar cell units, each of which consists of two different types of semiconductor materials, usually silicon. When sunlight shines on the solar panel, photons excite electrons in the semiconductor material, causing it to transition from one energy level to another, thereby generating current. These currents are collected and transmitted to the output end of the solar panel for power supply or storage. The energy conversion module 3 is connected to a power transmission cable 1, and the energy conversion module 3 is used to introduce electrical energy into the ammonia electrolytic cell 14 through the power transmission cable 1. The second filter 12 is used to draw the passing air into the air compressor 13. The air in the air compressor 13 is used to pass into the bottom of the ammonia electrolytic cell 14 and then compress the air to produce nitrogen. The ammonia electrolytic cell 14 is provided with a top opening 17 for air discharge. The compressed air passed into the ammonia electrolytic cell 14 reacts with the nitrogen after contacting with the cathode 15 and the anode 16, and causes the cathode 15 to generate ammonia.

[0032] The ammonia electrolysis cell 14 generates ammonia through the reaction of nitrogen in the air and hydrogen ions generated by electrolysis, and the ammonia dissolves in water to form an ammonia-water mixture. The most common raw materials can be used to produce fertilizers.

[0033] The cathode 15 of the electrolysis is made of a multi-layer woven mesh made of inert metal titanium, and the surface of the woven mesh is plated with a molybdenum disulfide catalyst film, which is activated. The gas generated by the electrolysis cathode is ammonia. Since the solubility volume ratio of ammonia in water is 1:700, the ammonia concentration of a saturated ammonia solution under normal pressure is 33%. The ammonia generated by the electrolysis method is basically dissolved in water, and no ammonia bubbles are generated. Ammonia water is obtained by electrolysis ammonia water production technology. The electrolysis chemical equation of the cathode 15 is as follows: N2+6H2O→2NH3+6OH - .

[0034] The electrolytic anode 16 is made of a multi-layer titanium braided mesh with no catalyst on the surface. The electrolytic anode 16 directly gathers with the bubbling air to the top opening 17 of the ammonia electrolytic cell 14, and is discharged from the ammonia electrolytic cell 14 along with the electrolyte circulation system. The electrolytic equation of the electrolytic anode 16 is as follows: 2H2O→O2+4H + .

[0035] Among them, the fertilizer mechanism includes a water inlet pipe 4, a water storage tank 5, a drain pipe 8, a first filter 9 and a circulation pump 10. The circulation pump 10 is a device for circulating the fluid in the system. It is generally widely used in many fields such as heating systems, air conditioning systems, water supply systems, industrial production processes, etc. The circulation pump generates power through a driving device (usually an electric motor) so that the fluid circulates along a pipe or pipeline, thereby realizing the transportation and circulation of the fluid. The second filter 12 and the first filter 9 are filters. The filter is a device for filtering impurities in liquid or gas. It is usually composed of a filter medium and a shell. The filter medium can be a filter screen, a filter cloth, a filter element, etc., and the shell can be metal, plastic, glass, etc. When the liquid or gas passes through the filter medium, the impurities are captured by the filter medium, and the pure liquid or gas passes through the filter medium. A filter screen 51 for blocking foreign objects from the outside is provided on the top of the water tank 5. A baffle mechanism is provided on the top of the water tank 5 for preventing foreign objects from falling into the water tank 5 when cleaning the foreign objects on the filter screen 51. Circulating water 6 is provided inside the water tank 5. The circulating water 6 is used to pass through a drain pipe 8, a first filter 9, a circulating pump 10 and an ammonia electrolytic cell 14 in sequence. The cathode 15 in the ammonia electrolytic cell 14 is electrolyzed to generate ammonia, which is then used to pass through the water inlet pipe 4 on the limit block 7. The ammonia electrolytic cell 14 is used to discharge the circulating water 6 through the drain pipe 8 so that the oxygen generated by the anode 16 is discharged into the atmosphere. The ammonia generated in the ammonia electrolytic cell 14 dissolves with the circulating water 6 to generate fertilizer.

[0036] Secondly, the baffle mechanism includes a pair of mounting grooves 59 opened at the top of the water storage tank 5, and drawers 52 are slidably arranged inside the mounting grooves 59, and pull handles 18 are fixedly connected to the drawers 52. A pair of limit blocks 7 are provided on the drawers 52 for limiting the sliding distance of the drawers 52 to the mounting grooves 59, and a pair of support bars 11 are provided on the top inner wall of the water storage tank 5 for supporting the drawers 52 to slide. The drawers 52 are provided with magnetic strips 19 for attracting each other at the ends close to each other. The magnetic strips 19 that attract each other usually refer to the phenomenon that two magnetic strips or magnetic objects attract each other and stick together due to magnetic force. This phenomenon is caused by the interaction between the magnetic fields generated by the magnetic objects. Magnetic objects are usually made of materials such as iron, nickel, and cobalt, and they will attract each other and stick together when they are close. The magnetic strips 19 are provided with sealing rubber pads 53 for making the connected ends of a pair of drawers 52 closely attached to each other. The sealing rubber pads 53 prevent the connected ends of the drawers 52 from being adsorbed to form gaps, causing water and impurities to pass through the gaps. A pair of water outlets 54 are provided at the end of the drawer 52 away from the suction, and an inclined surface is provided on the inner bottom of the drawer 52 for guiding the water inside the drawer 52 to the water outlet 54. The function of the inclined surface is to make the water automatically flow to the end with the water outlet 54, thereby saving time and effort when discharging the sewage in the drawer 52.

[0037] Furthermore, a pair of water outlet pipes 55 are connected to the drawers 52, and the water outlet pipes 55 are fixedly connected to the corresponding water outlets 54. A clamping block 58 is movably inserted at one end of the water outlet pipe 55 away from the drawer 52. The material of the clamping block 58 is rubber, and the function is to make one end of the water outlet pipe 55 tightly blocked by the clamping block 58 to prevent sewage from flowing out of one end of the water outlet pipe 55 at will. A blocking block 56 is fixedly connected to one end of the clamping block 58, and a gripping handle 57 is fixedly connected to the end of the blocking block 56 away from the clamping block 58.

[0038] In this embodiment, when the solar power generation system is needed, the light emitted by the sun is irradiated onto the solar panel 2. After the solar panel 2 generates electricity, it converts the electric energy into the energy conversion module 3. In the energy conversion module 3, the voltage and current of the electric energy are converted into the voltage and current of the ammonia electrolysis cell 14. The energy conversion module 3 can also store a part of the energy. The energy conversion module 3 introduces the electric energy into the ammonia electrolysis cell 14 through the transmission cable 1. The air is drawn into the air compressor 13 after passing through the second filter 12, and then passed into the bottom of the ammonia electrolysis cell 14. The compressed air bubbles the liquid water electrolyte, and the compressed air contacts both the cathode 15 and the anode 16 of the electrolysis. One purpose of bubbling is to provide nitrogen to the cathode 15 of the electrolysis, and the nitrogen is electrolyzed on the cathode 15 to generate ammonia; another purpose of bubbling is to stir the liquid water electrolyte to prevent the liquid water electrolyte from having a concentration gradient during the electrolysis process, thereby reducing the electrolysis efficiency.

[0039] When it is necessary to convert solar electricity into fertilizer production process equipment or direct agricultural application, the water storage tank 5 contains circulating water 6 at this time. The circulating water 6 enters the circulating pump 10 through the drain pipe 8 and the first filter 9 in sequence, and the circulating pump 10 pumps the circulating water 6 into the ammonia electrolytic cell 14. After the ammonia generated by the electrolysis of the cathode 15 is dissolved in the ammonia electrolytic cell 14, the water in the water inlet pipe 4 is discharged into the water storage tank 5 through the water inlet pipe 4 of the water storage tank 5. While the ammonia electrolytic cell 14 is drained, the excess bubbling air and the oxygen generated by the electrolytic anode 16 are also discharged. The excess bubbling air and the generated oxygen are separated at the top opening of the water storage tank 5 and discharged into the atmosphere. The ammonia generated in the ammonia electrolytic cell 14 is dissolved in the circulating water 6. When the ammonia concentration of the circulating water 6 in the water storage tank 5 reaches a certain standard, the circulating water 6 of the entire water storage tank 5 is emptied, and can be used for fertilizer production process equipment and direct agricultural application, or new circulating water 6 is filled into the water storage tank 5.

[0040] When it is necessary to clean the filter screen 51 on the top of the water storage tank 5 and prevent the foreign matter cleaned on the filter screen 51 from falling into the water storage tank 5, it is only necessary to Figure 2As shown, the connecting ends of a pair of drawers 52 are first attracted by the magnetic strip 19, and then the sealing rubber pad 53 is used to increase the sealing of the connecting ends of the drawers 52. At this time, the filter 51 can be cleaned, and all the foreign matter that falls off will fall on the drawer 52. Finally, water is poured on the drawer 52. Since the upper surface of the drawer 52 is inclined toward the water outlet 54, the water can carry the foreign matter on the drawer 52 to flow toward the water outlet 54. Then, the gripping handle 57 is pulled outward from the water storage tank 5 to drive the block 58 and the gripping handle 57 to disengage from one end of the water outlet pipe 55, and the container can be used to catch the sewage flowing out of the water outlet 54 and the water outlet pipe 55 to clean the drawer 52. Finally, the pair of drawers 52 are pulled outward with force, so that the water storage tank 5 and the filter 51 can work normally, which is simple and easy to operate.
