Background technology:
At present, with the pure water be raw material electrolysis ozone generator multiple structure arranged, for example: the patent No. that the inventor proposes to Patent Office of the People's Republic of China is that the utility model name of ZL200520113829.9 is called the utility model patent of " a kind of anode construction of electrolysis ozone generator ".Also have Chinese patent application 97122126.X, denomination of invention is the patent of invention of " electrolytic ozone generator ".
Said structure has following shortcoming:
1, ozone has extremely strong oxidation corrosion, in operational process, the tightness system of large volume directly contacts with ozone, because of the big easier oxidation corrosion that is subjected to ozone of surface-area, through after the long-play, it is aging to cause the tightness system physical property to take place, and sealing property descends, and then seal failure, make the leakage of the gas and the raw water of its generation.
2, adopt many places tightness system mode to seal, the complexity that not only increases cost or operating procedure is become, and all can't avoid fully being corroded by ozone oxidation with the ozone contact area is how tiny, and cause seal failure.
3, through after the long operation, the tightness system of silicon rubber material can't be resisted the oxidation corrosion of high-concentrated ozone, fast age hardening, follow the string, and cause seal failure.
4, after fastening, fastening force provides tightness system deformable seal and anode catalyst layer to compress needed two pressure of proton exchange membrane simultaneously, owing to make needed power of tightness system deformable seal and anode catalyst layer compress the needed power of proton exchange membrane and inequality, to cause that the opposing party's is stressed excessive or too small, sealing property or anode catalyst layer and proton exchange membrane snap-in force are affected, cause the membrane electrode electrolysis ozone generator unstable properties, and then the ozone generation amount descends.
5, after through operation, the attenuation gradually of the thickness of anode catalyst layer, and after the thickness attenuation, clam member can't continue the pressure that provides enough, also can't compensate the pressure that is lost because of after the thickness attenuation fast, directly make the anode construction of electrolysis ozone generator loose, anode catalyst layer and proton exchange membrane snap-in force deficiency descend the ozone generation amount of membrane electrode electrolysis ozone generator.
6, conventional cathode construction has negative electrode retaining plate, anticorrosion, framework, flow deflector, tightness system, anode micro porous plate, cathode catalyst layer etc., therefore, part is of a great variety, increases to produce and the assembling complexity, and then influence product reliability, cause production cost to improve.
