The necessity of measuring ozone concentration: Ozone is a strong oxidant, with strong bactericidal disinfection, bleaching, deodorization and other characteristics, so it is widely used in water disinfection, food processing sterilization and purification, food storage and preservation, medical and health care and household disinfection and purification of products. In the production and application of ozone generator, a certain ozone concentration is an important parameter to ensure the effect of disinfection and oxidation, save energy and prevent pollution.
Second, the ozone production of the generator is its main and most basic technical index, and the production is calculated by measuring the ozone concentration. Strictly speaking, there is no reliable means of determining the ozone concentration, it is impossible to produce qualified products, the current market ozone generator production misrepresentation of counterfeiting is mainly manifested in the absence of ozone concentration indicators or untrue. So, we would like to take an experiment for ozone concentration changes in our model: QLO-10G, 10G oxygen source ozone generator with different oxygen flow rates.
Our oxygen source ozone generator inner built with 5L/min oxygen production tower. So we will adjust the flow meter from 1LPM to 5LPM at this experiment, then to see the result how it is. ( Noted: Before turn on the ozone generator machine, please ensure the ozone concentration knob must be minimum or less 30%, so as to protect from 100% start-up power to cause power board burn.)
The experimental conditions: Room temperature, oxygen production 3L/min, ozone production 10G/H, ozone concentration fixed.
Below is our experiment test result, adjusted the flow meter from 1L to 5L.
- Adjusted the oxygen concentration to 1L/min, the real-time ozone concentration output around at 102mg/L.
- Adjusted to 2L/min, ozone concentration at 79~80mg/L.
3. Adjusted at 3L/min, ozone concentration at 66mg/L.
4. Adjusted to 4L/min, (at this time oxygen concentration lower than 90%), real-time ozone concentration around 53mg/L.
5. Adjust to 5L/min, ozone concentration at 46Lmg/L.
Above experiment show the conclusion we have drawn is that, under stable oxygen concentration, the smaller the gas volume, the higher the ozone concentration. Because if the flow rate is too high, it will be too short time to convert more oxygen, so the proportion of air in the airflow is a little more, resulting in a low oxygen concentration. On the contrary, if the flow rate is relatively small, the ozone generator can fully convert the gas inside, the total amount of oxygen formed does not increase, but the proportion of oxygen increased, the natural oxygen concentration also increased.
