Description
Technical Field
The invention relates to the technical field of ozone generating equipment, in particular to an electrolytic water ozone generator with a membraneless structure.
Background
Ozone has been widely used for over a century as a water treatment disinfectant in the wastewater and water reuse industry. The transition to alternative disinfectants (i.e., non-chlorine) including ozone is motivated by the United States Environmental Protection Agency (USEPA) regulations. These require potable water facilities to optimize the inactivation of protozoan pathogens and viruses to prevent the formation of disinfection by-products (DBPs) primarily associated with chlorine disinfection. Ozone is a broad-spectrum, high-efficiency green germicide. Due to its extremely strong oxidizing ability, the biological structures of microorganisms such as bacteria, viruses, etc. are destroyed in an extremely short time. In addition, ozone is easy to decompose into oxygen, is harmless to human body, and has no secondary pollution, which is an advantage that other bactericides cannot compare with.
The electrolysis method is a method for generating ozone by electrolyzing an oxygen-containing electrolyte by using a low-voltage direct-current power supply. Before the 80 s of the 20 th century, the traditional electrolytic method is carried out in electrolyte with oxygen acid and salt as environment, but the method has the defects of complex electrolyte formula, small electrolytic area, low ozone yield and high operation cost, and is greatly limited in practical application. With the rapid development of the technology for preparing ozone by an electrolytic method, an ion exchange membrane/proton exchange membrane is used as a Solid Polymer Electrolyte (SPE) to replace the traditional electrolytic method technology, and becomes a most representative electrochemical ozone synthesis technology. The technology replaces the prior liquid electrolyte with the ion exchange membrane, and can be applied to the liquid with low conductivity to generate ozone. The main reactions are as follows:
anode reaction:
3H 2 O→O 3 +6H + +6e -
in the use of electrolytic techniques for disinfection, there are two key ways to achieve an efficient process. First is the anode used. Among the many anode species, boron doped diamond coated (Boron Doped Diamond, BDD) electrodes are one of the most effective electrode materials. BDD has a wider potential window and conductivity than other electrode materials, and can generate high concentration ozone in situ in the liquid. BDD is combined with ion exchange membrane to prepare O by electrolysis in liquid 3 Many problems are encountered during actual use. Due to the problems of poor mechanical property, poor stability and the like of the ion exchange membrane, the service life of the ion exchange membrane is extremely short and frequent replacement is required, so that the maintenance cost of the BDD ozone generator is greatly increased. Related enterprises in the industry need to purchase from Europe at high price, thus greatly improving the enterprisesThe production cost and the compression profit inhibit the development of the technology in China.
Therefore, the development of the water electrolysis ozone equipment without an ion exchange membrane is of great practical significance.
Disclosure of Invention
