The main ways of ozone production are: corona discharge method, electrolysis method, ultraviolet method, nuclear radiation method, plasma method and so on. Ozone generation technologies that have been put into use by food, hospitals, and pharmaceutical companies mainly include corona discharge and electrolysis.
Industrially, ozone is produced by corona discharge from dry air or oxygen by using an alternating voltage of 5 to 25 kV. In addition, ozone can be produced by electrolyzing dilute sulfuric acid at a low temperature or by heating liquid oxygen.
Electrolytic produce ozone
Ozone produced by electrolysis has the advantages of high concentration, pure composition and high solubility in water, and has extensive development value in medical, food processing and aquaculture and home use. However, compared with the corona discharge method, the electrolysis method produces a small amount of ozone and consumes a large amount of energy;
High voltage Corona e discharge method
The principle of corona discharge to produce ozone is to place a dielectric body (usually using hard glass or ceramic as a dielectric) between two parallel high-voltage electrodes, and maintain a certain discharge gap, When high-voltage current passing through the two poles, a uniform blue-violet corona discharge is formed between discharge gap. When air or oxygen passes through the discharge gap, oxygen molecules are excited by electrons and obtain energy, finally elastically collide with each other to polymerize into ozone molecules.
