Abstract
The utility model provides a ceramic electrode plate for ozone generation, which is directly composed of high voltage discharge electrodes, and the electrodes are made of semiconductor ceramic. The utility model needs no ceramic metallization or glass silver-plating manufacturing technology, and the electrodes adopt semiconductor ceramic; using requirements of high-temperature resistance, no moisture absorption and anti-oxidation can be reached, and the dielectric is directly replaced by oxide film on the semiconductor ceramic electrode; the fabrication technology and the integral structure of an ozone discharge device are simplified, the production cost is reduced, and the using service life and performance of the device are further improved.
Description
Discharge device in the utility model relates to a kind of " silent discharge " ozone equipment.
" silent discharge " produces ozone is present comparatively economical and practical method, use the ozonizer of this method to be divided into open type and enclosed two big classes, wherein the enclosed ozonizer is mainly used in various water treatment systems, be divided into tubular type and board-like again by structure, its discharge mode all is a gap discharge, and open type ozonizer production ozonize gas is mainly used in the space and article are handled, and its discharge mode is cylinder discharge or creeping discharge.Gas discharge device in the above-mentioned ozonizer is formed by the dielectric substance between high-voltage discharging electrode and two electrodes, and high-voltage discharging electrode wherein is metallic substance or other material with conductivity.Because ozone has very strong oxidation capacity, so be exposed to that discharge electrode in the gas generally adopts stainless material or with the surface of metal electrode antioxidation treatment.
Dielectric substance in the ozone-generating device is generally the non-metallic material that electronic ceramics or glass etc. have high insulating property, and the metal electrode of one of them adopts ceramic metallization or glass silvering technology to make.To the tube type generator spare in the enclosed ozonizer, the inwall metal electrode complex manufacturing technology of elongated dielectric substance pipe, technology, equipment requirements are very high, and the quality of batch process is difficult to guarantee.High frequency creeping discharge ozone in the opposite opened ozonizer brings out battery lead plate, and the discharge electrode that ceramic metallization is made is because the oxidation of ozone and the humidity of Working environment, and the oxide film of formation needs frequent scouring and influences work-ing life of ozone-generating device itself.
Non-maintaining creeping discharge ozone is provided by the electroplax plate (patent No.: 96232699.2) provide a kind of creeping discharge also can prevent that the electrode metal on the electronic ceramics thin slice is oxidized, life-time service need not to keeping discharge effect scouring discharge electrode, and promptly non-maintaining ozone brings out battery lead plate.It adopts ceramic sheet to make electrode base sheet, the applying electronic ceramic metalizing process, make the discharge electrode that inhomogeneous field distributes on the positive and negative surface of substrate, and corresponding spraying or the very thin one deck of sintering is high temperature resistant, anti-oxidant, the non-metallic material of strong adhesion cover on the discharge metal electrode of front, make electrode metal and be ionized to the gas-insulated of ozonize, the oxidation corrosion of avoiding ozone counter electrode metal is to realize non-maintaining function and to prolong the work-ing life that ozone brings out battery lead plate.Because the spark temperature during geseous discharge is very high, add in the medium-term and long-term use of ozone environment, require to cover the discharge electrode metal nonmetal thin layer high temperature resistant, antioxidant property is very high, according to non-metallic material and the material sintering process that present electronic ceramics uses, the resistance to elevated temperatures that improves nonmetal thin layer must improve sintering temperature when changing material.Because the electrode metal of ceramic metallization when reaching the temperature of sintering non-metallic material thin layer severe oxidation can take place, cause the complete processing difficulty of the material performance requirement of the nonmetal thin layer that covers metal electrode to improve.
Task of the present utility model provides a kind of need not to adopt ceramic metallization or glass silvering technology, has the ceramic electrode ozone generation discharge device of non-maintaining function equally.
Task of the present utility model is to realize by following proposal: ceramic electrode ozone brings out battery lead plate directly to be made up of high-voltage discharging electrode, and electrode adopts semiconductive ceramic to be made.Semiconductor ceramic material has certain electric conductivity, can form high-voltage electric field,, have high temperature resistant, nonhygroscopic, oxidation resistant characteristics simultaneously.Material surface can form the oxide film with insulating property by nature in manufacturing processed, can serve as the dielectric substance in the ozone discharging electrode." silent discharge method " is to make gas generation corona discharge by the dielectric substance between high-voltage electric field and discharge electrode, its physical process mainly is a high-voltage electric field, the current power of discharge electrode is very little, so utilize the conductivity of semiconductive ceramic to form high-voltage electric field, make dielectric substance with the oxide film on semiconductor ceramic material surface self and just can realize the gas corona discharge, produce ozone.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is the utility model gap discharge electrode arrangement.
Fig. 2 is the utility model creeping discharge electrode arrangement.
As shown in the figure, the utility model directly is made up of two high-voltage discharging electrodes 1, and electrode adopts semiconductive ceramic to be made.Electrode 1 can be tubulose, is provided with discharging gap 2 between two electrodes or is not provided with discharging gap.Do not establish two electrodes of discharging gap, directly make another electrode therein on one of the plate electrode, this electrode is strip and block and distributes.
The utility model has the advantages that to need not ceramic metallization or glass silvering manufacturing process that electrode adopts and partly leads The body pottery can reach high temperature resistant, nonhygroscopic, anti-oxidant instructions for use, and dielectric substance is directly by semiconductive ceramic Oxide-film on the electrode replaces, and has simplified the processing technology of ozone discharge device and the structure of complete machine, reduces and gives birth to Produce cost, further improved service life and the serviceability of device.
