Abstract
Description
Technical Field
[0001] This invention belongs to the field of ozone water preparation technology by electrolysis, specifically relating to a low-pressure constant current water electrolysis ozone generator. Background Technology
[0002] Ozone has strong oxidizing properties and a broad-spectrum bactericidal and disinfecting effect. It can kill vegetative bacteria and spores, viruses, fungi, etc., and can destroy botulinum toxin. It also has a strong effect on removing mold, fishy smells, and other odors. It has increasingly wide applications in industries such as disinfection, water treatment, medicine and health, and food preservation.
[0003] The electrolytic method for ozone production was established in 1840. It primarily involves electrolyzing water using low-voltage direct current, causing an oxidation reaction at the anolyte interface to produce ozone. The ozone production device consists of an electrolyte solution and two electrodes: an anode and a cathode. Ozone is evolved at the anode, and the cathode can be of two types: a hydrogen evolution cathode and an oxygen reduction cathode.
[0004] Currently, existing ozone generators suffer from unstable ozone water quality due to various issues, including water quality, during the ozone production process. Utility Model Content
[0005] In view of this, this utility model proposes a low-pressure constant current electrolytic water ozone generator, which can solve the problem of unstable ozone concentration in existing ozone water preparation equipment.
[0006] This utility model is implemented as follows:
[0007] This utility model provides a low-pressure constant current electrolytic water ozone generator, including a base, a reactor shell fixed on the upper surface of the base, and an electrolysis component for preparing ozone water by electrolysis fixed inside the reactor shell; wherein, a low-pressure constant current control module for controlling the stable output of electrolysis current is fixedly installed inside the base.
[0008] Based on the above technical solution, the low-pressure constant current electrolytic water ozone generator of this utility model can be further improved as follows:
[0009] Furthermore, the low-voltage constant current control module includes a main control MCU, a voltage protection module, a voltage regulation module, and a voltage feedback module; the power supply is connected to the power input interface of the main control MCU through the voltage regulation module and grounded through the voltage protection module; the power switch port of the main control MCU is connected to the fixed bracket one through the voltage output line; the fixed bracket two is connected to the main control MCU through the voltage feedback module.
[0010] The beneficial effects of adopting the above-mentioned further solutions are as follows: by setting up a main control MCU, the output current state can be autonomously controlled to ensure the stability of the current flowing between the anode and cathode, thereby ensuring a constant concentration of ozone water produced per unit time; by setting up a voltage protection module, the circuit can be protected to avoid fires caused by short circuits or open circuits; by setting up a voltage feedback module, the returned current can be detected and used in conjunction with the main control MCU to control the current in the circuit.
[0011] Furthermore, the electrolysis assembly includes an anode and a cathode for electrolyzing water, with one cathode and one anode. The cathode is located above the anode, and the anode and the cathode are separated by a first fixing bracket and a second fixing bracket. The first fixing bracket passes through both the anode and the cathode, while the second fixing bracket only passes through the cathode.
[0012] Furthermore, there are two cathodes and one anode. The cathode is located between the two anodes, and the anodes and cathodes are separated by a first fixing bracket and a second fixing bracket. The first fixing bracket penetrates the anodes and the cathodes, while the second fixing bracket only penetrates the anodes and the cathode located below them.
[0013] Furthermore, the top of the reactor shell is provided with a water inlet for adding electrolyzed water into the equipment; the upper surface of the reactor shell near the base is provided with a water outlet for discharging the ozone water formed after electrolysis; both the water inlet and the water outlet are sealed with caps.
[0014] Furthermore, the cathode is made of stainless steel, and the surface of the anode has a titanium-iridium-ruthenium alloy coating.
[0015] The beneficial effect of adopting the above-mentioned further scheme is that ozone can be generated rapidly by electrolyzing the solution by setting a titanium-iridium-ruthenium alloy coating on the anode surface.
[0016] Furthermore, both the anode and the cathode surfaces are provided with trench structures.
[0017] The beneficial effects of adopting the above-mentioned further scheme are: by setting up a trench structure, the contact area between the anode, cathode and solution is increased, thereby improving the yield.
[0018] The technical advantages of this low-pressure constant-current electrolytic ozone generator are as follows: This invention improves the structure and process, increasing the effective electrolysis area within a smaller space, significantly improving the ozone generation rate. The low-pressure current control module detects the current in the circuit and maintains a constant current, ensuring a constant concentration of ozone in the electrolyzed water regardless of water quality, thus guaranteeing stable ozone water quality. By utilizing this equipment, operating costs are reduced, equipment lifespan is extended, energy consumption is low, and it has a wide range of applications, resulting in significant economic benefits.
