What problems should be paid attention to in the design of mobile ozone generator application system?

When the mobile ozone generator is used in water treatment projects and other occasions, many factors will affect its efficiency and reliability. Therefore, the design of mobile ozone generator application system should pay attention to the following issues.

 Mobile ozone generator

1. The original gas of generator is not allowed to contain hydrocarbon, corrosive gas or any other substance that can react in oxygen / ozone / corona environment, thus endangering or damaging the safety of equipment. As we all know, the three elements of explosion are:

Fuel, oxidant and ignition, as well as the corona environment of ozone generator, have two kinds, namely oxidant and ignition. Therefore, it is necessary to prevent the presence of hydrocarbon fuel materials in feed gases; if hydrocarbons are possible, they must be safe, and when the hydrocarbon concentration is close to 25% of the low explosion limit (LEL), the power supply is cut off with a hydrocarbon analyzer.

In the medium of PTFE, it can decompose into fluorocarbon, such as glass. Circulating coolant around the corona chamber may leak through the seal.

And into the corona space, resulting in the dielectric surface to form a layer of coating, coating. When this happens, the media must be cleaned regularly because the coating reduces the efficiency of ozone production. In addition, the feed gas should be filtered. Prevent small desiccant powder or other particles from entering the corona area of the generator except for particles about 5 m. In order to avoid affecting corona efficiency.

2. The supply pressure cannot be changed uncontrollably. Due to the influence of pressure on corona power induction and dielectric voltage, the operation of generator is not reliable due to the wide range of pressure variation. Beyond the corona power range, fuses or automatic circuit breakers may be damaged. Exceeding the applied voltage peak will lead to premature dielectric failure.

3. When designing the ozone generator system, a large amount of water must be prevented from entering the generator. The blockage of float valve of water seal compressor or condensate valve on air dryer will cause water inflow into corona chamber of generator. A large amount of water in corona chamber will lead to corona concentration, high current density and local medium heating, resulting in premature dielectric failure. Even if the detection device cuts off the corona power supply before the water enters the corona chamber, the impurities in the water will deposit on the components.

Work on the surface must be continued before these impurities are removed. Failure or error in operation may force the treated wastewater from the ozone contact cell into the generator, or at least generate it. Dielectric damage or corona. In addition, the system design and operating procedures must prevent flammable and corrosive gases and water vapor returning from the ozone contact cell from entering the generator.

4. The quality of cooling water is good to prevent scaling, so as not to affect the cooling effect of the generator. Second, for water-cooled generators, the quality of cooling water is very important to reduce the scale of heat transfer surface. Fouling will reduce heat transfer efficiency.

Reduce ozone production and increase maintenance costs. Technically, tap water is the coolant of choice, but economically, the water consumed by large industrial generators may not be attractive. Water treatment plants have a system.
