Abstract
The invention discloses a cathode structure for a membrane electrode electrolysis ozone generator. The cathode structure comprises a proton exchange membrane (6), a cathode catalyst layer (7), and a cathode micropore plate (8). The cathode structure is characterized in that: the cathode structure is provided with a cathode fixing plate (1) which is provided with a screw hole (2), a drainage hole (4) and diversion grooves (3); the diversion grooves are communicated with each other through slots (5) and are communicated with the drainage hole (4) . The cathode structure overcomes the defects of great varieties of conventional parts, has a simple structure, a simple preparation process and convenient assembly, improves the product reliability and reduces the production cost.
Description
Technical field:
The present invention relates to a kind of is the cathode construction of the membrane electrode electrolysis ozone generator of raw material with the pure water, belongs to the electrolysis ozone generator technical field.
Background technology:
At present, with the pure water be raw material electrolysis ozone generator multiple structure arranged, for example: Chinese patent application 97122126.X, denomination of invention is " electrolytic ozone generator " patent of invention.
Said structure has following shortcoming:
Cathode construction has negative electrode retaining plate, anticorrosion, framework, flow deflector, sealing-ring, microwell plate, cathode catalyst layer etc., and therefore, part is of a great variety, increases to produce with assembling complicatedly, and then influence product reliability, causes the production cost raising.
Summary of the invention:
The objective of the invention is to overcome the deficiency of above-mentioned prior art and provide a kind of simple in structure, preparation technology is simple, easy to assembly, the cathode construction of the membrane electrode electrolysis ozone generator that cost is low, product reliability is strong.
The present invention can reach by following measure: a kind of cathode construction of membrane electrode electrolysis ozone generator, it comprises proton exchange membrane, cathode catalyst layer, cathode micro porous plate, it is characterized in that it is provided with the negative electrode retaining plate, the negative electrode retaining plate is provided with screw hole, water vent, the negative electrode retaining plate is provided with diversion trench, be communicated with by groove between the diversion trench, and be communicated with water vent.
In order further to realize purpose of the present invention, described diversion trench is an annular diversion trench.
In order to realize that further purpose of the present invention, described negative electrode retaining plate adopt the metal titanium material to make.
Compared with the prior art the present invention has following positively effect:
The negative electrode retaining plate of cathode construction of the present invention is provided with screw hole, is used for the integral body and the cathode electrode that is connected direct supply of fastening membrane electrode ozonizer, with conventional negative electrode retaining plate identical function is arranged.The negative electrode retaining plate is provided with diversion trench, can hold raw water, and raw water and gaseous product convection current, diffusion in groove have conduction and refrigerating function, with conventional flow deflector identical function are arranged.The negative electrode retaining plate is provided with water vent, the water and the gaseous product of negative electrode can be discharged smoothly by water vent.The negative electrode retaining plate adopts the metal titanium material to make, and prevents its corrosion, without any need for rot-resistant material and rot-resistant treatment process.Therefore the negative electrode retaining plate has the function that fastening, water conservancy diversion, cooling, aqueous vapor are discharged, combine conventional negative electrode retaining plate, anticorrosion, all functions of framework, flow deflector, compare with the ozonizer of prior art, preparation technology is simple, easy to assembly, and then reduces cost 20～30%.
