How to use the ozone generator safely
1. The ozone generator installation personnel must undergo technical training before starting maintenance;
2. When using ozone machine for sterilization, it is strictly forbidden for workers to work and work in a high concentration ozone environment;
3. Remember to handle the power supply disconnection and ozone depletion during maintenance or repair of the equipment, which can ensure the safe maintenance of personnel;
4. If there is any abnormality, please immediately power off or notify professional personnel for maintenance.
5. Qualified special grounding wire, safe and reliable grounding, it is forbidden to install in the danger zone where ammonia gas is easy to leak or there is danger of explosion. 6. The application method of the process ozone generator should be known and can be operated skillfully. Disinfection equipment.
7. If an ozone leak occurs, it is necessary to turn off the ozone generator and turn on the ventilation equipment for ventilation. Immediately exit the space where the ozone generator is used, and the residual ozone in the space will fall into the safe range and then enter.
The use of ozone generators should pay attention to the problem <br> <br> ozone generator when used in water treatment engineering and so on, there are many factors that may affect the efficiency and reliability of the generator, it is necessary in the design of the ozone generator applications Note the following questions:
(1) The generator material gas must not contain hydrocarbons, corrosive gases and any other substances that can react in the oxygen/ozone/corona environment, thereby causing damage or damage to the safety of the equipment.
It is well known that the three elements of an explosion are fuel, oxidizers and fires, and two of the corona environments in the ozone generator are oxidants and fires. It is therefore necessary to prevent the inclusion of hydrocarbon fuel materials in the feed gas; if hydrocarbons are likely to be present, a hydrocarbon analyzer must be installed to shut off the power supply when the hydrocarbon concentration approaches 25% of the lower explosion limit (LEl).
Fluorocarbons, such as Teflon or coolant, can decompose in corona to form fluorine, which can attack glass dielectric materials and accelerate dielectric damage. The circulating cooling fluid surrounding the outside of the corona may leak through the seal and enter the corona space, resulting in a lacquer, coating on the surface of the dielectric. When this happens, the dielectric must be cleaned periodically as this coating reduces the efficiency of ozone production.
In addition, the feed gas should also filter out particles of about 5 μm to prevent small desiccant powder or other particles from entering the generator corona zone. So as not to affect the corona efficiency.
(2) The supply pressure cannot be changed uncontrollably. Since the air pressure affects the corona power induction and the voltage applied across the dielectric, a wide range of pressure changes can make the generator operation unreliable. Exceeding the corona power range can cause the fuse or automatic breaker to open. Exceeding the applied voltage peak can also cause premature failure of the dielectric.
(3) The ozone generator system must be designed to prevent large amounts of water from entering the generator.
The float valve on the water-sealed gas supply compressor or the condensate valve on the air dryer is blocked and jammed, causing the generator to corrode indoors. A large amount of water in the corona chamber can cause corona concentration, high current density, and local dielectric heating, causing premature failure of the dielectric. Even if the detection device cuts off the corona power before the water enters the corona chamber, impurities contained in the water will deposit on the surface of the component, and these impurities must be removed before continuing to operate. Operational faults or operational errors can force the treatment of effluent from the ozone contact pool to the generator, at least causing corona component contamination or dielectric damage. In addition, system design and operating procedures must prevent flammable corrosive gases and water vapor returning from the ozone contact pool from entering the generator.
(4) The water quality of the cooling water should be good to prevent scaling, so as not to affect the heat dissipation effect of the generator.
The second pair of water-cooled generators said that in order to reduce the scale of the heat transfer surface, the quality of the cooling water is very important. Fouling reduces heat transfer efficiency, which reduces ozone production and increases maintenance costs. Technically, tap water is the preferred coolant, but the use of tap water is economically unattractive for the water consumption required for large industrial generators, except perhaps when the system is used in a water treatment plant. Contrary to the quality of tap water, the treated sewage is generally not used as cooling water because it is prone to fouling. If high-quality water or other fluids are used in the sealed ten cooling circuits, the final heat exchanger is specifically designed to have less fouling; it is easy to clean, and the effluent can also be used as the final stage of heat dissipation. In order to achieve a good balance between water and equipment maintenance costs, most of the system design uses high-quality drinking water from cooling tower water or heat exchanger (no suspended solids, chloride <5mg/L).
(5) For air-cooled generators, the cooling air must be free of moisture, impurities, corrosive, aerosol, oily or conductive materials and visible dust. Under normal circumstances, unless it is in an extremely dusty industrial atmosphere, most of the air does not need to be filtered.
