ozone generatorIt is a commonly used equipment in our daily lives and plays an important role in the fields of disinfection and sterilization. Ozone molecules can effectively prevent food decay and mold, and can eliminate odors indoors and at train stations. It can also be used to remove pesticide residues from vegetables and fruits. Many users and friends do not know how to choose when purchasing ozone equipment for the first time. Let's talk about it in detail below.
When purchasing an ozone generator, scientific methods should be adopted, taking into account the emission medium, gas source, cooling technology, power supply, and application objects comprehensively.
1. Ozone emission medium. The ozone generator cylinder is the core component of the ozone generator and is also a component that is prone to failure. Its quality directly affects the discharge voltage and efficiency of the ozone generator. Most common ozone generator emission media on the market are made of glass. Instantaneous discharge of glass materials produces high ozone concentration, but has a short service life and unstable operation. Under the same power supply, the ozone output of ceramic media is slightly lower than that of glass media, but its service life and stability are stronger than those of glass media. The disadvantage is that the output of a single discharge tube cannot exceed 20 grams per hour. Enamel medium has strict requirements for gas source, high cost and easy damage.
2. Ozone gas source. Ozone is produced from oxygen as a raw material. Oxygen raw materials refer to oxygen of different concentrations, including oxygen and air. The concentration of oxygen has a significant impact on the concentration and production of ozone. The oxygen content in the air is only 21%, so the concentration of ozone generated by the air source is relatively low, and nitrogen compounds are also produced while producing ozone. The purity of oxygen in bottled or oxygen generators exceeds 90%, and the concentration of ozone produced by the oxygen source is very high. In water treatment, priority should be given to using oxygen to generate ozone.
3. Ozone power supply. High voltage discharge is a common way of generating ozone, which requires an ozone discharge power source to provide energy. The power supply determines the working efficiency of the ozone emission medium. An increase in power frequency can reduce the size of equipment, lower discharge voltage, and improve system safety and reliability. When choosing an ozone generator, it depends on whether it is a high-frequency inverter power supply, whether it has frequency and width adjustment functions, and the peak value that can be achieved.
4. Cooling technology. During the process of generating ozone through high-voltage discharge, high temperatures are generated. When the temperature reaches above 40 ℃, it will reduce the concentration and production of ozone, so it needs to be cooled to cool the ozone generator. The conventional cooling methods are divided into air cooling and water cooling, with water cooling being more effective than air cooling. At present, the cooling methods are internal and external polar water cooling and air cooling. Good heat dissipation effect, can effectively reduce ozone concentration, output power, and equipment lifespan.
5. Control system. The ozone generator system can be controlled through the main console and can achieve linkage between the circulation pump and the booster pump. The control system needs to have various interlocking protection functions, such as short circuit protection, cooling water overheating protection, transformer overheating protection, cabinet switch protection, etc.
