The working principle of the ozone generator is:
The use of high-pressure ionization (or chemical, photochemical reaction), so that part of the oxygen in the air decomposition and polymerization of ozone, isotopic transformation process of oxygen; can also be obtained using electrolysis of water. The instability of ozone makes it difficult to realize the bottle storage, generally only the use of ozone generators on-site production, with the production and use.
Gap discharge ozone generator is ozone in the gap between the inner and outer electrodes to produce ozone, ozone can be centrally collected and output the use of its higher concentration, such as for water treatment.
Open generator electrodes are exposed in the air, the ozone produced by the direct diffusion into the air, because of the lower concentration of ozone is usually only used for small space air sterilization or surface disinfection of certain small items.
The gap discharge generator can be used instead of the open generator. However, the cost of gap discharge ozone generators is much higher than that of open type.
Expanded Information:
Ozone generator according to the way ozone is generated, there are three main types: high-voltage discharge type, ultraviolet irradiation type, electrolytic type.
1, high-voltage discharge generator
This type of ozone generator is the use of a certain frequency of high-voltage current to create a high-voltage corona electric field, so that the electric field or electric field around the oxygen molecules electrochemical reaction, so as to create ozone.
This type of ozone generator has the advantages of mature technology, stable work, long service life, ozone production (single machine up to 1Kg/h), so it is the most widely used ozone generator in the related industries at home and abroad
2, ultraviolet ozone generator
This type of ozone generator is the use of a specific wavelength (185mm) ultraviolet irradiation of oxygen molecules, so that the oxygen molecules decompose and produce ozone. Oxygen molecules decompose and produce ozone. Due to the large size of the ultraviolet lamp, ozone production is low, the use of short life, so the use of this generator is narrower, commonly used in the disinfection of the dishwasher on the use.
3, electrolytic generator
The characteristics of this type of ozone generator is the use of a new type of PEM membrane with a low-pressure DC conduction solid membrane electrode positive and negative electrolysis of deionized water, water in the special anode solution interface in the form of proton exchange is separated into hydrogen and oxygen molecules, hydrogen from the cathodic solution interface is discharged directly, oxygen molecules in the anode interface due to high-density current produced by the electron Oxygen molecules are energized at the anode interface by the excitation of electrons generated by the high-density current and polymerize into ozone molecules.
