Why does ozone sterilization have to have the concentration of ozone?


Ozone is greatly utilized as a environmentally friendly disinfectant, ① drinking h2o, industrial wastewater, domestic sewage, swimming pool h2o remedy and healthcare facility sewage treatment ② air sterilization and disinfection of raw elements, processing gear and venues in medicine in the food industry and pharmaceutical market. Cleaning and disinfection ③ preservation and transportation of fruits, vegetables and food ④ ozone remedy and ailment prevention in medicine ⑤ bleaching of pulp and textiles in chemical industry ⑥ water procedure in aquaculture ⑦ domestic area air purification Disinfection, degradation of residual pesticides on the floor of vegetables, melons and fruits ⑧ Air sterilization, deodorization, and odor removal in livestock and poultry breeding crops.

At current, there are three principal techniques to crank out ozone on the current market, and the industrial ozone generator is commonly based mostly on the basic principle of corona discharge, simply because the volume of ozone necessary is rather substantial.

1. The basic principle of corona discharge

2. Theory of UV mild

3. The basic principle of electrolysis of h2o

The basic principle of manufacturing ozone by corona discharge is expressed by the components, E=U/D (E = F / q, E = KQ / r2), P=I2R, E is the electric powered area energy created by static energy, when E is greater than the air is ionized At the critical worth of the field strength, air ionization commences, that is to say, the air gets to be a conductor, and there are cost-free electrons in it. The electrons are freed from the bondage of the nucleus, the oxygen molecules are decomposed into oxygen atoms, and the oxygen atoms are swiftly produced with oxygen. ozone.

How does the area toughness E of the electrical discipline appear from? In the stainless steel ozone tube, there are a lot of compact electrodes related alongside one another in parallel and then connected to the electric power supply. The transformer continually boosts the 220V or 380V of the mains ability source to 3000V-6000V. The ability higher than will develop into bigger and larger sized, and the power is Q (E = KQ / r2).

There will be a quartz tube isolation exterior the electrode as insulation protection. We all know that the air is non-conductive below standard conditions. Constantly boosting the voltage, the electric power Q on the electrode will improve, and at the similar time, these electrical energy Q will enhance the electric field energy about the electrode. When the electric field toughness fashioned by these electrical power Q dispersed on the area of the electrode starts to be greater than the electrical field toughness of the ionized air, The air is ionized and can carry out electrical energy. There will be totally free electrons in the air.

These electrons appear from oxygen and nitrogen molecules, so oxygen and nitrogen develop into oxygen and nitrogen atoms, and these oxygen atoms circulation as a result of the within of the ozone tube. The air or oxygen reacts chemically to generate ozone, and at the same time there will be a tiny sum of nitrogen. Some will inquire, isn’t there other gases in the air? Those people are inert gases, a problem does not respond, why can a corona discharge generate a whole lot of ozone at a time? We can style and design the stainless metal ozone tube according to the fuel flow, these kinds of as how several liters for each moment. To raise the hourly ozone production, the ozone tube can increase the number of electrodes. There are usually two kinds of gases that we deliver ozone, namely air and oxygen. The concentration of ozone made by air is 18-35 grams per cubic meter, and the ozone manufactured by oxygen is 80-120 grams for every cubic meter. In the electrode discharge procedure, in accordance to the P=I2R electric electrical power, we know that it will produce a great deal of warmth, so we need to have drinking water cooling to take absent this warmth, if we really don’t get it, one particular will influence the existence of the device, and the other is Will reduce the output of ozone, since the temperature raises ozone will accelerate the decomposition.

How generally does the corona discharge generate the ability of the ozone device? 

A, 50-60Hz

B, 400-1000Hz

C, >1000Hz

The higher the frequency, the scaled-down the quantity requirement of the ozone generator (the lesser the power offer), the decreased the energy use, and the much larger the ozone output, but the specialized specifications are high. www.ceenvironment.com

What is the partnership amongst the ozone generation for each device time of the ozone generator?

1. The structure and processing precision of the ozone generator

2. Cooling solutions and circumstances

3. Driving voltage and driving frequency

4. Dielectric content (quartz glass)

5. Oxygen information and cleanliness and dryness in uncooked gas

6. Efficiency of generator energy procedure (superior performance, considerably less warmth conversion)

Why does ozone sterilization call for ozone concentration?

The detection conventional of ozone sterilization is the CT worth, C is the ozone concentration, T is the retention time just after the ozone concentration reaches the standard, this kind of as drinking h2o ozone sterilization, CT=1.6 C=.4ppm, T=.4 minutes, the essence of ozone sterilization in h2o, In reality, it is the potent oxidizing ability of the oxygen atoms produced by the decomposition of ozone in the water and the complete total of ozone in the h2o alone.
