Abstract: Ozone generator is an electronic device that artificially converts oxygen into ozone. It is widely used in food, beverage, fruit and vegetable processing, medicine, pharmaceuticals, breeding, pollution control and other fields. The working principle of the ozone generator is to ionize oxygen through high-voltage discharge and then polymerize it into ozone molecules. When installing an ozone generator, you need to pay attention. Because too high an ozone concentration will cause certain hazards, the installer needs to be trained and the user should be skilled in operation. In addition, the ozone generator also needs to be placed in a dry and spacious place. Pay attention to safe use. Let me introduce you to the relevant knowledge of ozone generator. Working principle of ozone generator
Ozone generator is a process that uses the principle of high-voltage discharge to convert oxygen into ozone. That is, high-voltage alternating current is applied to a high-voltage electrode with an insulator in the middle and a certain gap to allow the dry and purified air or oxygen to pass through. When the high-voltage alternating current reaches 10-15KV, a blue glow discharge is generated. The free high-energy ions in the corona dissociate O2 molecules and polymerize into O3 molecules through collision.
It can also be obtained by electrolyzing water. The instability of ozone makes it difficult to store in bottles. Generally, it can only be produced on-site using an ozone generator and used as produced. There are three main types of ozone generators based on the way ozone is produced: high-voltage discharge type, ultraviolet irradiation type, and electrolysis type.
Applications and ozone dosage of ozone generators in various water treatment industries:
1. Application in food processing industry: such as production water, production workshops, packaging rooms, changing rooms, Sterile room, production equipment, tools, etc.
2. Application in beverage processing industry: such as pure water, mineral water, production water for various beverages, production workshops, packaging rooms, changing rooms, sterile rooms, production equipment, tools, etc.
3. Application in the fruit and vegetable processing industry: fruit and vegetable storage, preservation, processing, production water, production workshops, packaging rooms, changing rooms, sterile rooms, production equipment, tools, etc.
4. Application in cold storage: preservation and extended storage of fruits and vegetables, grains, eggs, meat, aquatic products, etc.
5. Application in pharmaceutical industry: such as production water, central air conditioning system, workshop, changing room, sterile room, etc.
6. Application in the pharmaceutical industry: such as pharmaceutical factories, hospital wards, beds, linens, operating rooms, medical equipment, sterile rooms, etc.
7. Application in breeding industry: such as chicken, fish, vegetable greenhouses, etc. for sterilization, disinfection, deodorization, air purification, etc.
8. Used in public places: such as hotels, restaurants, schools, Internet buses, waiting halls, etc. to purify the air and prevent cross-infection.
9. Application in drinking water: such as deep well water, municipal water supply, secondary pressurized water supply, and rural drinking water.
10. Used in reclaimed water, sewage, waste water and waste gas.
11. Used in water purification and air purification in swimming pools and swimming pools.
Note: Calculation of ozone demand: g/h of ozone required for water treatment = 1.06 coefficient × ozone dosage g/m3 × water volume m3/h.
Ozone generator installation precautions
1. Ozone generator installers must undergo professional technical training before installation and maintenance.
2. During installation, install the equipment in a dry and spacious place to facilitate heat dissipation and maintenance.
3. Ensure that the electricity, gas, and water inlet and outlet pipelines are connected correctly.
4. The capacity of the lines used meets the requirements to ensure that fire hazards are eliminated.
5. High pressure is dangerous, do not flush the equipment with water.
6. Cannot be placed near a substation.
7. Qualified special grounding wires, safe and reliable grounding, are prohibited from being installed in dangerous areas where ammonia gas is prone to leak or there is a risk of explosion, and are kept away from high-voltage lines.
8. The ground should not be wet.
9. There should be a certain amount of space (≥300mm) around the equipment.
10. If ozone leakage occurs, it is necessary to turn off the ozone generator as soon as possible, turn on the ventilation equipment for ventilation, and then exit the space where the ozone generator is used immediately, and wait until the residual ozone in the space drops to a safe range. Enter
