[0002] Nitrogen fertilizer is an indispensable raw material for agricultural crops, but the increasing price of nitrogen fertilizer has created a burden on the production of high-quality crops. Photocatalytic nitrogen fixation technology has reformed the production method of nitrogen fertilizer and reduced the cost of nitrogen fertilizer. At the same time, the emergence of corresponding devices has enabled this technology to be promoted and applied.

[0003] The existing traditional industrial nitrogen chemical production methods usually rely on the Haber-Bosch process, which is a process for synthesizing ammonia through the catalytic reaction of hydrogen and nitrogen under high temperature and pressure. However, this process requires a lot of energy consumption and high pressure conditions, produces a large amount of carbon dioxide (CO2) emissions, and has a serious impact on the environment.

[0004] The existing new nitrogen fixation devices use light drivers, which makes them expensive, and the input costs are not proportional to the benefits. They cannot be promoted to farmland, and they cannot react on cloudy days and at night, which makes it difficult to fix the catalyst during the reaction, short product life, and insufficient mixing reaction between the catalyst and reactants. In addition, the existing devices also have problems such as insufficient use of sunlight, lack of environmental protection, inability to replace catalysts, inability to detect product concentration, and inconvenient product movement to ensure that they meet the standards.

The plate 8 has an S-shaped transparent glass test tube with a volume of 18L embedded in the reaction-occurring part. The test tube is used to provide a place for storing water, air and catalysts. The photocatalytic nitrogen fixation reaction is carried out under light conditions. The S-shaped transparent glass test tube is connected to the water bucket 19, the product collection bucket 20 and the nano bubble generator through the first rubber connecting tube 5, the second rubber connecting tube 7 and the third rubber connecting tube 6 respectively. The nano bubble generator converts air into nano-scale bubbles and melts them into water, thereby increasing the solubility of nitrogen in water. A water pump is set in the water bucket 19 to pump the water bucket 19. The water in the reaction chamber is pumped into the S-shaped transparent glass tube through the first rubber transmission tube by pressure to react; the two ends of the reaction chamber on the left side are also provided with semi-circular arc-shaped condensers 10, and the reaction chamber is also fixed with a plurality of LED purple light lamps 1 along the S-shaped curve of the S-shaped transparent glass tube and on the condenser 10, which are used to manually turn on the reaction chamber to provide light supplement or illumination on cloudy days or at night, and pulleys 18 are also provided around the bottom of the fixing seat 17, and a left cabinet door 16 and a right cabinet door 15 are opened at the water bucket 19 and the product collection bucket 20, and a rubber connecting tube is provided in the middle. There is an electric valve 4, which is connected to a single-chip microcomputer. Each rubber connecting pipe is connected to an S-shaped transparent glass test tube after the electric valve 4. The tilt angle of the panel 11 is calculated according to the optimal tilt angle calculation formula, and the tilt angle of the panel 11 is controlled by changing the height of the front clamping position 12 and the rear clamping position 13. The optimal tilt angle in winter is obtained by multiplying the latitude by 0.9 and adding 29°. The optimal tilt angle in summer is obtained by multiplying the latitude by 0.9 and then subtracting 23.5°. The optimal tilt angle in spring and autumn is obtained by subtracting 2 from the latitude.5°, the wavelength of the LED ultraviolet lamp 1 is 360nm~420nm, the S-shaped bottom of the S-shaped transparent glass test tube is connected to the first rubber connecting tube 5, the second rubber connecting tube 7 and the third rubber connecting tube 6 through interfaces respectively, and fixed by buckles, the interface at the bottom opening of the S-shaped transparent glass test tube connected to the product collection barrel 20 is provided with a three-layer PTFE organic filter membrane 9, which can filter the built-in catalyst to prevent the outflow of the catalyst, and is tightly fixed by a reinforced clamp, and the tops of both sides of the S-shaped transparent glass test tube are respectively provided with pH meter fixing Plug 2, PH meter fixed plug 2 is equipped with a PH detector, one end of the PH detector is close to the lower side of the test tube, in close contact with the product, and one end is exposed to the air and connected to the single-chip microcomputer. When the reaction reaches the expected time of the timer, the PH detector is started to detect the concentration of the product. If the product concentration reaches the standard concentration, the single-chip microcomputer controls the electric valve 4 to open and release the product. An exhaust pipe 3 is also set at the top of the middle of the S-shaped transparent glass test tube, and the pipe mouth is 3cm long. The exhaust pipe 3 discharges the excess bubbles introduced by the nano bubble generator during the reaction from the reaction device to ensure the normal pressure environment of the reaction. .

[0034] In this embodiment, the second rubber connecting tube 7 transports the product to the product collection barrel 20 after the reaction is completed, and different functions are controlled and used by the electric valve 4 controlled by the single chip microcomputer at different times and under different needs.

[0035] In this embodiment, the reinforced clamp is an O-ring structure.

[0036] In this embodiment, the solar panel is connected to a battery to facilitate the use of the device on cloudy days. The solar panel is also connected to a control board with a relay, which is connected to the LED purple light 1 for controlling its on and off.

[0037] In this embodiment, the catalyst is first arranged in an S-shaped transparent glass test tube.

[0038] When the utility model is in use, if nitrogen fertilizer needs to be produced on a sunny day, the device can be directly used for production. If it is cloudy or at night, the LED purple light 1 needs to be manually turned on for supplementary lighting or illumination. At the same time, the sunlight or the light emitted by the LED purple light 1 can be converged by the condenser 10 and more concentrated on the reaction device. After determining the lighting conditions, under the control of the single-chip microcomputer, the electric valve 4 turns on the water pump and the nano bubble generator at the same time. After the action of the generator, the air becomes nano-level bubbles, and the bubbles and water are simultaneously passed through the transmission tube to the reaction test tube, which increases the solubility of nitrogen in water and allows the reaction to be more complete. At the same time, the bubbles provided by the nano bubble generator allow the air to form an impulse between the water and the catalyst, which plays a stirring role, so that the water dissolved with nitrogen and the catalyst are fully mixed and react. After the time specified by the timing device, the electric valve 4 is controlled by the single-chip microcomputer to turn off the water pump and the nano bubble generator, stop water and ventilation, The reactants are allowed to react in the reaction generating device for a period of time. When the reaction time set by the timing device is reached, the electric valve 4 is controlled by the single chip microcomputer to open the pH detector to detect the product concentration. If the expected concentration is not reached, the above steps are repeated again to react until the expected product concentration is reached and the reaction is stopped. The electric valve 4 is controlled by the single chip microcomputer to open and release the product. When the product passes through the bottom of the test tube, under the action of the PTFE (polytetrafluoroethylene) PTFE organic filter membrane 9, only the product will flow out, and the catalyst will be isolated by the filter membrane inside the transparent test tube to continue the next reaction. The product is drained to the product collection barrel 20 through the rubber transmission tube for storage.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution, which should be included in the scope of the claims of the utility model.
