Laboratory Ozone Generator
What is laboratory ozone generator?
Laboratory ozone generator is an equipment device to produce ozone. Ozone has sterilization, oxidation, decolorization, deodorization and other effects, so the ozone generator is widely used in pharmaceutical, medical equipment, water treatment, chemical, and other industries. Ozone is in temporary storage and cannot be stored. If ozone is needed, it must be produced on-site. Therefore, ozone generators are required for all applications where ozone is needed.
The laboratory ozone generator is used as a system that ozone unit includes the ozone generator body, air preparation equipment, ozone dosing equipment, ozone mixing equipment, ozone reaction equipment, and ozone exhaust gas decomposition equipment. In some cases, activated carbon filters are added as ozone adsorption and removal equipment.
Working principle of laboratory ozone generator
Ozone is unstable and has strong oxidizing power. Ozone is recognized worldwide as a broad-spectrum, highly effective disinfectant. It is produced by using air or oxygen as raw material with high frequency and high voltage discharge. Ozone is a strong oxidizer that can rapidly kill bacteria in the air at a certain concentration. There is no toxic residue, and no secondary pollution, so it is known as the cleanest oxidizer and disinfectant.
Features of laboratory ozone generator
A. Sterilization
Laboratory ozone generator is a broad-spectrum, highly efficient, fast, bactericide instrument. The use of an ozone generator can rapidly kill bacteria that constitute pathogenic viruses and microorganisms in humans and animals. Ozone is a very strong oxidizing substance. It has an oxidizing effect and can destroy the biological structure of bacteria, viruses, and other microorganisms in a short period. Compared to other biocides, ozone is fast and harmless to humans.
B. Detoxification
Through oxidation reaction, ozone can effectively remove toxic gases, ozone generators such as C0, SO2, mustard gas, etc. Ozone is soluble in water. Water containing ozone effectively removes oxides from water and facilitates the decomposition of toxic substances such as heavy metal ions, organic toxins, cyanide, sulfide and dichlorvos, oxymetholone, malic acid, etc.
Advantages of laboratory ozone generator
A. Non-polluting
After ozone sterilization, it will quickly decompose itself into oxygen. No residue, no secondary pollution, it is an environmentally friendly germicidal disinfectant.
B. Easy to operate
Laboratory ozone generators can solve the problem of laboratory sterilization and disinfection. It can also be used for testing, oxidation, etc.
C. Economic
There is a misconception that using an ozone generator is costly. However, the energy consumption of using an ozone generator is relatively small and it helps to control production costs.
Types of laboratory ozone generator
There are three main types of laboratory ozone generators currently available according to the way ozone is produced. They are high-pressure discharge ozone generator, ultraviolet irradiation ozone generator, and electrolysis ozone generator.
A. High-pressure discharge ozone generator
The high voltage discharge ozone generator uses a certain frequency of high voltage current to create a high voltage corona electric field, which causes an electrochemical reaction of oxygen molecules in or around the electric field to create ozone.
a. Types of high voltage discharge ozone generator
| Basis of classification | Type | Description |
|---|---|---|
| High voltage electrical frequencies | a. Industrial frequency (50-60Hz) b. Medium frequency (400-1000Hz) c. High frequency (>1000Hz) | The industrial frequency generator has been withdrawn from the market due to the disadvantages of its large size and high-power consumption. Medium and high-frequency generators have the advantages of small size, low power consumption, and large ozone yield, and are now the most commonly used products. |
| Gas raw material | a. Oxygen ozone generator b. Air ozone generator | Oxygen ozone generators are usually supplied with oxygen from oxygen cylinders or oxygen generators, while air ozone generators usually use clean and dry compressed air as the raw material. Since ozone is produced by oxygen, and the oxygen content in the air is only 21%, the concentration of ozone produced by air-type generators is relatively low. In contrast, the oxygen purity of bottles or oxygen generators is above 90%, so the ozone concentration of oxygen-type generators is higher. |
| Cooling type | a. Water-cooled ozone generator b. Air-cooled ozone generator | Ozone generator will generate a lot of heat when working, so it needs to be cooled, otherwise, the ozone will be generated while decomposing due to high temperature. Water-cooled generator has a good cooling effect, stable work, no ozone decay, and it can work continuously for a long time. However, due to the complex structure, the cost is a little higher in comparison. The cooling effect of an air-cooled ozone generator is not good enough, and the ozone decay is obvious. |
| Dielectric material | a. Quartz tubes b. Ceramic plates c. Ceramic tubes d. Glass tubes e. Enamel tubes | With low cost and stable performance, quartz dielectric is one of the earliest materials used in the artificial manufacture of ozone, but the mechanical strength is poor. Ceramic is similar to quartz, but ceramic is not suitable for processing, especially in large ozone machines is limited by use. Enamel is a new type of dielectric material. It has a high mechanical strength of dielectric and electrode in one. It can be precision machined with high accuracy and is widely used in large and medium-sized ozone generators, but the manufacturing cost is high. |
| Ozone generator structure | a. Dielectric barrier discharge (DBD) ozone generator b. Open type ozone generator | The structure of the dielectric barrier discharge (DBD) ozone generator is characterized by the generation of ozone in the gap between the inner and outer electrode zones. Ozone can be collected and exported for use in a centralized manner, and its concentration is high. The electrodes of an open-type ozone generator are exposed to the air, so the ozone produced is diffused directly into the air. As a result, it has a lower ozone concentration and is usually used only for air sterilization in smaller spaces or for surface disinfection of certain small items. Dielectric barrier discharge (DBD) ozone generators can be used instead of open-type ozone generators. However, the cost of a dielectric barrier discharge (DBD) ozone generator is much higher than the open type. |
B. Ultraviolet Ozone Generator
Ultraviolet ozone generators use ultraviolet light of a specific wavelength (185mm) to irradiate oxygen molecules to make them decompose and produce ozone. Due to the large size of the UV lamp, low ozone yield, and short service life, the use of this generator is narrow.
C. Electrolysis ozone generator
Electrolytic ozone generators usually produce ozone by electrolyzing pure water. This generator can produce a high concentration of ozonated water. It has the advantages of low manufacturing cost and simple use and maintenance. However, due to the disadvantages of low ozone yield, and the short life of electrodes, ozone is not easy to collect, and its scope of use is limited. At present, this generator is only used in some specific small equipment or some specific places and does not have the conditions to replace the high-pressure discharge generator.
How to use laboratory ozone generator?
Ozone machine uses
a. Place the ozone generator. Check that the ozone silicone hose is connected to the ozone output tube of the machine. Put the ozone output tube to the target position.
b. Close the doors and windows. Prohibit people from entering and leaving at will.
c. Connect the power supply, the voltmeter shows the current voltage. Turn on the gas pump switch, the gas pump indicator light is on and the gas pump starts to work.
d. Turn on the ozone switch. Depending on the current air temperature, humidity and time, the machine takes 1~30 seconds to start. The ozone indicator light on means the machine starts working.
e. Turn the timing switch to set the running time. If there is no timer, then you need to turn off the ozone generator manually.
f. After the set time is reached, the ozone generator will stop working automatically or need to be turned off manually. Please unplug the power in time.
g. Ozone will automatically decompose into oxygen after half an hour indoors. You can stay indoors for a long time only after you can’t smell the odor of ozone.
h. After use, please move the ozone generator to a dry and ventilated place to avoid water accumulation in the high-temperature environment, which will affect the ozone generator.
Precautions when using laboratory ozone generator
a. Prohibit the use of ozone generators in the presence of conductive gases or explosive media in the environment, because laboratory ozone generators generally use high-frequency high-voltage power supply.
b. When operating under a high temperature or impurity oil content gas environment, the ozone generator units are easily stained or derived from the spot scale. They should be cleaned in time.
c. The requirement of using the environment is that the air humidity is less than 95%.
d. When ozone is generated by a pure oxygen source or spectral method or hydrolysis method, the purity of ozone is high and will not cause any harm to human health. However, if ozone is generated with ordinary air, NOx will be generated along with the improper selection of dielectric materials or devices.
e. Ozone has a strong oxidizing ability. When using it, it should be kept away from rubber products, steel, and other items to avoid being corroded. In addition, ozone can stimulate the human respiratory system, which can cause serious injury.
