Method for keeping activity of electrolytic ozone generator

Abstract

The invention discloses a method for keeping the activity of an electrolytic ozone generator, which is characterized in that: a machine control system consisting of all control solenoid valves in the device is connected with a direct-current power supply (1); an ozone generator in the device is connected with a direct-current power supply (2); when the electrolytic ozone generating device operates, the direct-current power supply (1) provides control current for the machine control system, and the direct-current power supply (2) provides the operating current of a full-loaded membrane electrode for the ozone generator; and when the electrolytic ozone generating device stops operating or does not operate, the direct-current power supply (1) stops outputting the current, and the direct-current power supply (2) continues to provide continuous current, which is less than the operating current of the membrane electrode, of the membrane electrode for the ozone generator. In the method, the machine control system and the membrane electrode of the electrolytic ozone generator are subjected to power supply respectively by different power supply outputs, so that a membrane electrode system of the electrolytic ozone generator is always in the high-activity state, and the electrolytic ozone generator can exert high performance when used at any time, and high-yield ozone gas can be generated upon the startup of the electrolytic ozone generator.

Description

Technical field: [0001] The invention relates to a method for maintaining the activity of an electrolytic ozone generator, which belongs to the technical field of electrolytic ozone generators. Background technique: [0002] At present, the current supply of the membrane electrode of the electrolytic ozone generator using deionized water as raw material basically adopts the control method of providing current at full load during operation and completely disconnecting when the operation is stopped. [0003] Above-mentioned control method has following shortcoming: [0004] 1. Since the process of using the product is the continuous power-on and power-off process of the electrolytic ozone generator, the core component of the electrolytic ozone generator technology is the perfluorosulfonic acid resin proton exchange membrane. The proton exchange membrane relies on organic substances to form proton channels. The ozone generator is used to transport protons during operation. Th...

Problems solved by technology

The proton channel will be closed in the power-off state, and when the power is turned on next time, a large number of protons will enter the proton exchange membrane, but the proton channel has not been fully opened, which will cause the proton flow performance of the proton exchange membrane to be blocked and generate heat. The membrane electrode system of the electrolytic ozone generator, especially the proton exchange membrane, has a serious impact, which eventually reduces the service life of the entire membrane electrode, and even leads to the rapid death of the electrolytic ozone generator

[0005] 2. The activity of the membrane electrode of the electrolytic ozone generator will decrease as the shutdown or storage time increases. Therefore, the activity in the shutdown state continues to decrease, which will cause the membrane electrode to take a certain amount of time to reactivate when it is turned on again. In this certain period of time, the performance of the electrolytic ozone generator will be reduced.

At the same time, if the membrane electrode cannot be fully activated for a long time, the performance of the electrolytic ozone generator will be reduced, and the amount of ozone produced will be reduced.

[0006] 3. When the electrolytic ozone generator stops running, the membrane electrode current is completely disconnected, which will cause the proton channel of the proton exchange membrane to enter the closed state directly from the open state during operation, which will cause some protons to remain in the proton exchange membrane without passing through the proton channel. The anode side of the membrane, resulting in a sudden drop in the pH value of the anode side, causing damage to the proton exchange membrane and directly affecting the service life of the proton exchange membrane

[0007] To sum up, the membrane electrode current supply method of the existing electrolytic ozone generator cannot avoid the problems of frequent switching affecting the performance of the generator and the problem of downtime or long storage time.
