Abstract
The present invention provides electrolyzing type ozonizer anode structure. It includes electrolyte membrane, silicone rubber seal ring, multihole anode plate, and free lay mode formed granules of catalyst layer between said electrolyte membrane and multihole plate. Said anode structure has higher electrolytic efficiency, easily working and packaging.
Description
Technical field
The present invention relates to a kind of novel be the anode construction of the electrolysis ozone generator of raw material with the pure water.
Technical background
The anode that with the pure water is the electrolysis ozone generator of raw material has multiple structure, is 200410000314.8 the inventor to the application number that Patent Office of the People's Republic of China proposes, and denomination of invention has been put down in writing a kind of anode construction of electrolysis type ozone generator for the application for a patent for invention of " being used for anode construction of electrolysis type ozone generator and preparation method thereof ".This anode construction has proposed 2 improvement at known technology:
1, substitutes ventilative, permeable microwell plate with airtight, fluid-tight metal sheet and compress granules of catalyst; With the passage of the gap between the anode framework of itself and airtight, waterproof plate as raw water and electrolysate anodic gas.
2, the mode with " free lay " places granules of catalyst between solid electrolyte film and the positive plate, and by the fastening effect of bolt positive plate is pressed on the granules of catalyst of " free lay ", forms catalyst layer closely.
Through the inventor's further exploration discovery, the raising of above-mentioned ozonizer electrolytic efficiency is owing to the free lay of granules of catalyst brings.(for example: with tetrafluoroethylene granules of catalyst is sticked into be the catalyzer diaphragm) has bigger catalytic surface long-pending because the granules of catalyst that the granules of catalyst of " free lay " is placed than other method, thereby the efficient height of this ozonizer.Though with closely knit, airtight, fluid-tight metal sheet replaces microwell plate, can reduce the cost of ozonizer, this do not have obvious relation with electrolytic efficiency.The anode construction of the ozonizer described in above-mentioned No. 200410000314.8 applications for a patent for invention utilizes gap between anode framework and waterproof, air-locked positive plate as the passage of raw water and electrolysate anodic gas, thereby, the coordinating size precision of antianode framework and positive plate has very high requirement, has big difficulty on manufacturing process and assembly technology.
The content of invention
The object of the present invention is to provide " free lay " advantage that granules of catalyst brought of a kind of can the maintenance, be convenient to the electrolysis ozone generator novel anode structure of processing and assembling again.
For achieving the above object, technical scheme of the present invention is: a kind of anode construction of electrolysis ozone generator, it comprises: solid polymer dielectric film, porous metal plate, be clipped between described dielectric film and the microwell plate the layer of catalyst particles that forms through free lay and from all bandings around the described anode framework that forms catalyst layer through free lay.
Wherein, described porous metal plate is the micropore metal titanium plate that micropore surface has the conduction anticorrosion layer.
Wherein, the aperture in the hole of described microwell plate is 20 μ-300 μ.
Wherein, the anode framework of described anode framework preferred elastomeric.
Wherein, described anode framework is preferably silicone rubber O-ring.
Above-mentioned porous metal plate preferable alloy titanium plate.
The material of used same type component is identical in the used solid electrolyte film among the present invention, the material of granules of catalyst and No. 200410000314.8 applications for a patent for invention.
Anode construction of the present invention is assembling like this:
On side of solid polymer dielectric film, (opposite side is the electrolysis ozone generator cathode construction) puts the anode framework, pellet type catalyst (as the plumbic oxide particle) freely is laid on the intravital solid polymer dielectric film of anode frame, expanded metal (for example micropore titanium plate, the expanded metal surface has the conduction anticorrosion layer) on anode framework loam cake then.Method with machine riveting fastens as one whole electrolysis ozone generator anode construction, is about to solid electrolyte film, anode framework, expanded metal, and anode construction, and other auxiliary member is tightened to one.
Granules of catalyst in the anode construction of the present invention is owing to be " free lay ", thereby it is more abundant that granules of catalyst and solid polymer dielectric film have been had, more contact surface, so in electrolytic process, catalytic efficiency is higher on its contact surface.This performance and application for a patent for invention 20041000031.8 are suitable.But anode construction of the present invention has adopted microwell plate and anode framework to press the assembly method that cooperates again granules of catalyst has been compressed.This structure reduces greatly to the assembling requirement on machining accuracy of porous metal plate, and the result makes assembly technology convenient greatly.
Further specify the present invention below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is the diagrammatic cross-section of anode construction of the present invention.
Embodiment
Participate in Fig. 1, a kind of anode construction of having showed electrolysis ozone generator of the present invention among the figure, periphery at the relative another side of perfluor sulfanilamide (SN) cationic exchange membrane 1 (Nafionll7 of Du Pont) and electrolysis ozone generator cathode construction 5 is placed silicone rubber O-ring 2, free lay particulate state plumbic oxide 4 in silicone rubber O-ring 2, its particle diameter is 0.02-0.5mm, thereby form a plumbic oxide catalyst layer, its bed thickness is at 0.5-5mm.Smooth afterwards plumbic oxide catalyst layer; put on the plumbic oxide granular layer after smooth its surface can with the POROUS TITANIUM PLATE 3 of described silicone rubber O-ring 2 comprehensive engagements (POROUS TITANIUM PLATE surface treated have the anti-corrosion protective layer of conduction); the aperture of POROUS TITANIUM PLATE 3 is 20-300 μ, thereafter with anode framework and other auxiliary member 6 together with the cathode construction 5 fastening electrolysis ozone generator integral body that become.
This anode construction is when operation, and the micropore of raw water in micropore titanium plate 3 and the gap arrival dielectric film of catalyst particles intergranular in this electrolytic reaction take place, and the anodic gas of generation is extruded in the gap of catalyst particles intergranular and the micropore from the micropore titanium.
The working life of this anode construction was longer than 6000 hours, owing to replaced closely knit plate to make the dimension precision requirement of this plate be fallen generation with microwell plate, the packaging technology of whole anode construction is simplified.
