Method for photocatalysis of water by adopting nanometer porous titanium oxide film

Abstract

The invention discloses a method for photocatalysis of water by adopting a nanometer porous titanium oxide film. According to the method, clear water flows through a valve, a front filter, a flowmeter and an O-type split-flow ring to lead into a glass pipe cavity and then lead out of the O-type split-flow ring, and then the clear water flows through a rear filter and a mineral substance injector; and the inner wall of a glass pipe is provided with bamboo-shaped stabs which are criss-cross, a nanometer porous titanium oxide film is coated on the surfaces of the bamboo-shaped stabs, and an ultraviolet ray lamp tube is arranged in the middle of the stabs. The method for photocatalysis of water by adopting the nanometer porous titanium oxide film is utilized to prepare clean and oxygen-rich neutral activated water which has the advantages of strong seepage force, dissolving power and metabolism capability; and the method relates to self-cleaning of the glass pipe, and the glass pipe is semipermanent, the filter can be disassembled and washed, the filter can repeatedly be used, the mineral substance injector can supply and economy is excellent good.

Description

technical field [0001] The patent of the present invention uses the photocatalytic oxidation of nanoporous titanium oxide film to provide crops with a method of watering and fertilizing (adding 1‰N, P, K) neutral activated water, especially the method involves the inner wall of the glass tube The criss-cross bamboo shoot-like thrusting technique. Background technique [0002] At present, there are many products selling activated water in the domestic and foreign markets: drinking cups, kitchen water appliances, and water for aquaculture, crops, drinking water, beauty water, etc. Most of them adopt the world's most advanced "photocatalysis①②" technology. Nano-titanium oxide is one of the N-type photo-semiconductor materials with photocatalytic function. Under the irradiation of light, the excited titanium oxide surface generates electrons and holes, and then the holes will oxidize the water attached to the titanium oxide surface, and the The water turns into hydroxyl radical...

Problems solved by technology

[0004] "π water" device ③, the device is in the form of a cylinder, and the garden-shaped working core is composed of 8 overlapping layers, of which 6 layers of "π water" microporous ceramics and 2 layers of coalescing particles, no light source, the above existing The technical problem is: either functional refinement, or periodic core replacement, since their methods are in the realm of physical-mechanical methods

Although the "π water" technology involves a nano-catalysis method, the photocatalytic oxidation of the device is weak, and other functional cores are added to make up for it. It is easy to pollute and easy to block. It cannot be disassembled and washed, resulting in failure, or the core body will be disassembled after the total water output reaches 60 tons. replacement, resulting in high operating costs

The device adopts a microporous ceramic core with refined functions, which is only suitable for the high-quality water quality in Japan, especially not suitable for the water quality in my country, and it is difficult to promote
