What is ozone?
It is a strong oxidizing gas, which has the function of sterilization, bleaching, eliminating odor, decomposing formaldehyde and heavy metals and other harmful substances, and is widely used in the field of disinfection.
What is an ozone generator?
Is used to produce ozone gas (O3) device, is a good production, living tools, can effectively improve the safety and quality of food, drugs, cosmetics and other health products, improve human health level, ozone generator can be used in the food workshop disinfection.
Ozone is easy to decompose and can not be stored, and it needs to be prepared and used on site (in special cases, it can be stored for a short time), so all places that can use ozone need to use ozone generators. Ozone generators are widely used in drinking water, sewage, industrial oxidation, food processing and preservation, space sterilization and other fields. The ozone gas produced by the ozone generator can be used directly, or it can be mixed with the liquid through the mixing device to participate in the reaction. From the ozone generator action principle, main role, advantages, operating procedures to further understand the ozone generator.
First, the principle of ozone generator
The principle is: the use of high pressure ionization (or chemical, photochemical reaction), so that part of the oxygen in the air decomposition polymerization into ozone, is the isotropic transformation process of oxygen; It can also be obtained by electrolysis of water. The instability of ozone makes it difficult to achieve bottled storage, and generally can only be produced on site by using ozone generators. The classification of ozone generators is divided according to the way of ozone generation, there are three main types of ozone generators: one is high-voltage discharge type, the second is ultraviolet irradiation type, and the third is electrolytic type. According to the different installation methods, ozone generators can be divided into mobile ozone generators, wall-mounted ozone generators, portable ozone generators, horizontal ozone generators, vertical ozone generators and so on.
Second, the main role of ozone generator
1. Sterilization.
Studies have shown that ozone is a broad spectrum, efficient, rapid fungicide, ozone generator it can quickly kill a variety of human and animal disease pathogens, viruses and microorganisms. Ozone is a very strong oxidizing substance, the use of its oxidation, can destroy the biological structure of bacteria, viruses and other microorganisms in a short period of time, the ozone generator makes it lose the ability to survive. There are many compounds that use oxidation to kill microorganisms to achieve sterilization, such as common chlorine, bleaching powder, potassium permanganate and so on. However, these fungicides are not only slower than ozone sterilization, but also general fungicides are harmful to the human body.
2. Detoxification.
Ozone can effectively remove toxic gases through oxidation reactions, ozone generators such as C0, S02, mustard gas and so on. Ozone dissolved in water can be oxidized and decomposed to effectively remove toxic substances in water such as heavy metal ions, organic poisons, cyanide, sulfide, and pesticides such as dichlorvos, dimethoate, and mala sulfuric acid.
3, protection and preservation.
Due to the strong killing effect of ozone on bacteria and microorganisms, the ozone generator can use ozone water to treat meat and other foods to achieve the effect of anti-corrosion, elimination of odor and preservation. While ozone is produced, a large number of negative ions can also be produced, and some negative ions in the air can effectively inhibit the respiration of fruits and vegetables and delay their metabolic process. At the same time, ozone can kill the pathogenic bacteria that cause fruit and vegetable decay, decompose the metabolic waste produced in the storage process of fruits and vegetables with ripening effect, such as ethylene, alcohol, aldehyde, aromatic and other substances. In this way, under the action of ozone and negative ions, the metabolism of fruits and vegetables and the breeding and spreading of microbial pathogens are inhibited, so as to delay the subsequent ripening and aging, prevent its decay and deterioration, and achieve the effect of preservation. Studies have shown that ozone can prolong the storage period of food, beverages and fruits and vegetables by 3-10 times.
4. Deodorization and odor removal.
The main components that cause odor and corruption in nature are ammonia, hydrogen sulfide, methylmertan, dimethyl sulfide, dimethyl disulfide, etc., and ozone can react with them to oxidize and decompose into non-toxic, odorless substances, so as to achieve the effect of deodorization.
Iii. Advantages
In the field of industrial product production, the disinfection properties of ozone are used more by humans. Ozone sterilization has the advantages of fast, high efficiency, energy saving, environmental protection, no secondary pollution, etc., which is reflected in the following aspects:
1. Fast sterilization
Ozone mainly uses its strong oxidation for sterilization, the sterilization process is completed in an instant, and the sterilization speed is many times faster than chlorine and other disinfectants.
2. Sterilization broad spectrum
Ozone is a broad spectrum fungicide, not only can kill harmful bacteria, spores, viruses, fungi and protozoa and other microorganisms, but also can kill the destruction of botulinum toxin and rickettsia and so on.
3. Efficient sterilization
Ultraviolet disinfection has some problems such as short sterilization distance, weak sterilization ability, dead Angle, and low sterilization efficiency. Ozone is a kind of gas, produced by the ozone generator, can quickly diffuse to the food workshop, office areas and other places that need sterilization, and can avoid the problem of sterilization space dead Angle.
4. Environmental hygiene
After ozone sterilization, it will quickly decompose into oxygen, no residue, no secondary pollution, is an environmentally friendly disinfectant.
5.. Easy to operate
Ozone sterilization equipment can be installed in indoor or central air conditioning system, air purification system, large sterilization equipment, according to the concentration and time of ozone required for sterilization, automatically set the sterilization time of ozone sterilization equipment, easy to operate. The use of epoxy acetic acid, acetic acid, formaldehyde sterilization, the required time is longer.
6. Affordable
Many people believe that in the production process of food, drugs, cosmetics and other products, the use of ozone generators to sterilize, to consume a higher cost. Actually, this view is wrong. The use of ozone generators is simple, can be used by plugging, does not require complex operation, does not require professional personnel to use, which can save wages in terms of personnel. At the same time, the energy consumption of ozone generators is relatively small. From these aspects, the use of ozone sterilization is an economical sterilization method, which is conducive to controlling production costs.
Although the mobile ozone generator has many advantages in application, if it is not used correctly, it will not only fail to achieve the proper sterilization effect, but also cause malignant accidents such as combustion and explosion.
Four, ozone generator operating procedures
In order to improve the safety and effectiveness of the use of ozone generators, the following procedures should be carried out:
1. Ozone generators generally use high frequency, high voltage power supply, in the presence of conductors or explosive media in the environment, do not use ozone generators. When using ozone generators, safe operating procedures must be followed.
2. If the environmental health of the workplace is poor, it will affect the use of the ozone generator. For example, when used in a gas environment with high humidity or impurities and oil content, the ozone generator and device are easy to be contaminated with dirt or stain, which affects the amount of ozone generation and reduces the sterilization effect of ozone.
Mobile ozone generators should be cleaned in time after one year of use. When designing the ozone generator, the mechanical equipment factory should consider the convenience of replacing the device and facilitate the maintenance of the equipment.
