There are four main factors affecting the concentration of ozone produced by ozone generator

influence Ozone generator There are four main factors to produce ozone concentration: the structure and processing accuracy of ozone generator, cooling mode and conditions, driving voltage and driving frequency, oxygen content in raw gas, cleanliness and dryness. The following is a detailed introduction:
1. Structure and machining accuracy of ozone generator;
The ozone generator is mainly composed of four parts: ozone tube, high frequency power supply, fan and control system. Ozone tube is the core part of ozone generator. The electrode gap has a great influence on the concentration of ozone tube. The smaller the gap is, the greater the ozone concentration is. The ozone tube is designed and manufactured by using advanced tubular electrode with surface clearance. Under the strong ionization effect of high-voltage electric field, the high-speed electron impacts oxygen and decomposes it into oxygen atom. The high-speed electron has enough kinetic energy to form ozone through the collision reaction of oxygen atom, oxygen molecule and high-speed electron. The external power supply uses AC power supply, which is converted into DC power supply by step-down rectification for high-frequency power supply. The high-frequency power supply generates high-frequency voltage on the ozone tube to make the ozone tube work and convert oxygen into ozone gas. The working state of the fan and high frequency power supply is controlled by the control system, which mainly controls the working time of the ozone tube and plays the role of regulating the ozone output. The power supply of the fan is to supply the air source required for the operation of the ozone tube, accelerate the discharge of ozone gas generated by the ozone tube to the outside of the machine, and timely distribute the heat generated by the motor operation, so as to ensure that the working temperature of the motor is within the normal range.
2. Cooling mode and conditions;
Ozone is an unstable gas with strong oxidation. The output concentration of ozone is affected by many factors, among which the cavity temperature is one of the most important factors; when the ozone is about 30 ℃, it will reduce by half in one minute. The attenuation reaches 80% at 40 ~ 50 ℃. Over 60 ℃, ozone will decompose immediately.
3. Driving voltage and driving frequency;
In the control system, the two main executive components, fan and high frequency power supply, adopt modular design, with less wiring points and good insulation. One, the ozone output is stable and can be adjusted according to the actual demand.
4. The content of oxygen in the raw gas and its cleanliness and dryness;
The production of ozone is greatly affected by the oxygen content of the ozone generator. The influence of oxygen content in the gas on the ozone production was investigated. The concentration of ozone gas was measured according to the standard 1 of "measurement of ozone concentration, production and power consumption of ozone generator", and the ozone production was calculated according to the inlet flow rate. As shown in the table, the higher the oxygen content in the gas, the greater the ozone production. However, the oxygen content of and oxygen rich gas have little effect on the ozone production. Under the same operating conditions, the ozone production is basically the same.
In addition, the gas flow rate is an important parameter of the ozone generator, which has a great impact on the concentration and production of ozone. With the increase of gas flow rate, the ozone concentration decreases and the production increases, but when the flow rate increases to a certain value, the ozone concentration and production change little. Increasing the gas flow can increase the production of ozone, reduce the concentration of ozone, inhibit the decomposition of ozone, and reduce power consumption. Therefore, the gas flow can be determined according to the actual needs.
