[0024] Refer to Figure 1-6, the present invention provides a technical solution: a high-efficiency hypochlorous acid production device, including a box shell 1. The box shell 1 is successively provided with a lower layer chamber 11, a middle layer chamber 12, and an upper layer chamber 13 from bottom to top. An upper layer chamber 14 is provided in the upper layer chamber 13, a lower layer chamber 15 is provided in the lower layer chamber 11, a cathode column 4 and an anode column 5 are respectively provided in the middle layer chamber 12. The upper and lower ends of the cathode column 4 respectively penetrate through the upper layer chamber 14 and the lower layer chamber 15, and the upper and lower ends of the anode column 5 respectively penetrate through the upper layer chamber 13 and the lower layer chamber 11. An upper through hole 16 is provided at the upper end of the box shell 1 where the anode column 5 and the cathode column 4 are located, and a lower through hole 17 is provided at the lower end of the box shell 1 where the anode column 5 is located. A cylindrical diaphragm 6 is provided outside the anode column 5. The upper and lower ends of the cylindrical diaphragm 6 are respectively connected to the lower end of the upper through hole 16 and the upper end of the lower through hole 17. Scrubbing mechanisms 8 are respectively installed on the outer sides of the anode column 5 and the cathode column 4. A circulation system 7 and a circulation system 9 for controlling the operation of the scrubbing mechanism 8 are respectively installed on the box shell 1;

[0025] In this embodiment, the cathode column 4 is arranged at the center of the box shell 1, the anode column 5 is arranged outside the cathode column 4, and the number of the anode columns 5 is more than that of the cathode columns 4 to provide a larger contact surface area for the oxidation reaction and improve the reaction efficiency. In addition, the anode material and the cathode material for electrolysis adopt a columnar structural design, so that the contact with the electrolyte is more uniform and the reaction is more stable. At the same time, it is beneficial to cooperate with the scrubbing mechanism 8 to work. Among them, during the electrolysis process, gas molecules are generated when the surfaces of the anode column 5 and the cathode column 4 come into contact with the electrolyte. The gas molecule microbubbles gradually coagulate and increase in volume to form large bubbles. Until the buoyancy of the large bubbles is greater than the molecular attraction between the large bubbles and the surfaces of the anode column 5 and the cathode column 4, the large bubbles will break away from the surfaces of the anode column 5 and the cathode column 4. Therefore, during the period when the large bubbles do not break away from the surfaces of the anode column 5 and the cathode column 4, during the process of gas molecules coagulating into microbubbles and microbubbles coagulating into large bubbles, the contact area between the surfaces of the anode column 5 and the cathode column 4 and the electrolyte will be reduced, reducing the electrolysis efficiency. Therefore, through the design of the scrubbing mechanism 8, on the one hand, it is beneficial to scrape off the gas molecules generated on the surfaces of the anode column 5 and the cathode column 4 in real time, and / or accelerate the process of gas molecules coagulating into large bubbles, and separate the generated gas molecules from the surfaces of the anode column 5 and the cathode column 4 in the first time, so as to ensure and improve the contact rate between the surfaces of the anode column 5 and the cathode column 4 and the electrolyte in real time and improve the electrolysis efficiency. On the other hand, in the anode region of the anode column 5, gas molecules Cl 2 can be separated from the surface of the anode column 5 in the first time. After separation, the gas molecule Cl 2 has an extremely small volume, which further promotes Cl 2It reacts with water in the solution to generate hypochlorous acid. In addition, the scraping mechanism 8 can also have a real-time cleaning effect on the surface of the anode column 5 and the cathode column 4, so that the anode column 5 and the cathode column 4 have a higher electrolysis rate in real time.

[0026] In this embodiment, the scraping mechanism 8 includes a glass fan 81 arranged at the upper through hole 16, and the glass fan 81 is sleeved on the outside of the cathode column 4 or the anode column 5, and the lower end of the glass fan 81 is connected to a spiral glass strip 82, and the inner spiral surface of the spiral glass strip 82 is provided with a scraping surface 83 that fits with the outer surface of the cathode column 4 or the anode column 5.

[0027] In this embodiment, the scraping surface 83 is provided with protrusions 84, that is, the scraping surface 83 is provided with dense protrusions 84, so that there is a gap between the scraping surface and the surface of the cathode column 4 or the anode column 5, thereby reducing the friction effect and contact area with the surface of the cathode column 4 or the anode column 5, and at the same time, it is further beneficial for the gas molecules to detach from the surface of the cathode column 4 or the anode column 5.

[0028] In this embodiment, the circulation system 7 includes a circulation pipe 71, the upper and lower ends of which are connected to the upper cavity 13 and the lower cavity 11 respectively. A circulation pump 72 is installed on the circulation pipe 71. The circulation pump 72 performs extraction and circulation from bottom to top. When the solution passes through the upper through hole, it drives the glass fan to rotate, and the glass fan drives the spiral glass strip to rotate. In addition, under the driving and drainage action of the circulation pump 72, the gas molecules (Cl 2 ) is conducive to downward drainage, which is beneficial to Cl 2 The rise of Cl generates a certain resistance, which compresses the gas molecules 2 The effect is further beneficial to improve Cl 2 Reaction efficiency with aqueous solution.

[0029] In this embodiment, a pH detector 75 is installed on the circulation pipe 71 at the lower end of the circulation pump 72, and a control valve 73 is installed on the upper end of the circulation pump 72. The circulation pipe 71 located between the control valve 73 and the circulation pump 72 is connected to a collecting mechanism 74 to monitor the pH value of the solution in real time. When the solution reaches the required pH value, the control valve 73 is closed and the collecting mechanism 74 is opened to quickly obtain the prepared hypochlorous acid solution.

[0030] In this embodiment, a liquid level sensor 76 is provided in the upper chamber 13. The liquid level sensor 76 monitors whether the liquid level in the upper chamber 13 rises. If so, it feeds back to increase the operating power of the first circulation pump 72. If not, it feeds back to decrease the operating power of the first circulation pump 72. That is to say, when the liquid level rises, it means that the rising rate of gas molecules in the anode region of the cylindrical diaphragm is too fast. Under the driving and drainage action of the first circulation pump 72, the resistance to preventing the gas molecules in the cylindrical diaphragm from rising is small. Therefore, by increasing the operating power of the first circulation pump 72, the rising rate and rising effect of gas molecules can be reduced. When the liquid level does not rise, the operating power of the first circulation pump 72 can be reduced to reduce the falling rate and falling effect of gas molecules, thereby balancing the relative residence time of gas molecules (Cl 2 ) in the solution, which is beneficial to the reaction of gas molecules (Cl 2 ) with the aqueous solution.

The upper end of the second circulation pipe 91 is connected to the upper chamber 14, the lower end of the second circulation pipe 91 is connected to the gas collection tank 93, a second circulation pump 92 is installed on the second circulation pipe 91, and the lower end of the second circulation pipe 91 extends into the bottom of the gas collection tank 93. The upper end of the third circulation pipe 95 extends into the top of the gas collection tank 93, the lower end of the third circulation pipe 95 is connected to the middle chamber 12, a pressure valve 94 is installed on the top of the gas collection tank 93, and a second collection mechanism 96 is connected to the bottom of the gas collection tank 93; it is beneficial to timely discharge the gas molecules in the cathode region of the cathode column 4.

[0033] In this embodiment, the upper chamber 13 is connected to a liquid supply tank 2.

[0034] In this embodiment, a heat dissipation plate 3 is installed on the lower chamber 11 to be able to control the temperature of the electrolyte.
