Ultraviolet water sterilization device based on triboelectrification

Abstract

The invention provides an ultraviolet water sterilization device based on triboelectrification. The ultraviolet water sterilization device comprises a mechanical energy input device, a friction nano-generator, a belt transmission device, a water pump, an ultraviolet lamp, an input shaft and an output shaft, wherein an output end of the mechanical energy input device drives a rotor of the frictionnano-generator to rotate, and simultaneously drives the output shaft to rotate through the belt transmission device; the output shaft is connected with an input end of the water pump; the ultravioletlamp is spiral or over-flow type and comprises a lamp tube, a water pipe as well as a first electrode wire and a second electrode wire connected with a first output end and a second output end of thefriction nano-generator; one end of the water pipe serves as a water inlet and communicates with a water outlet of the water pump; and water to be sterilized is introduced into the water inlet of thewater pump. The ultraviolet water sterilization device provided by the invention combines the ultraviolet lamp with the friction nano-generator, enables collected mechanical motion to generate enoughhigh voltage through a triboelectrification effect, so that rare gas in the ultraviolet lamp tube is punctured and emits ultraviolet rays to realize conversion from mechanical energy to light energy,and the ultraviolet water sterilization device is simple and portable.

Description

technical field [0001] The invention belongs to the technical field of ultraviolet sterilizing devices, in particular to an ultraviolet water sterilizing device based on frictional electricity generation. Background technique [0002] Ultraviolet (UV) sterilization technology is relatively mature among many water sterilization methods, and has significant advantages. It can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in the cells of microorganisms by using ultraviolet rays of appropriate wavelengths, resulting in the death of growing cells and (or) the death of regenerative cells, so as to achieve the effect of sterilization . Ultraviolet sterilization generally has the following three advantages: first, it does not produce any disinfection by-products; second, ultraviolet sterilization is fast and effective; finally, its operation is safe and easy. Therefore, it has very important application value and significance to explore a...

Problems solved by technology

[0005] The disadvantages of this sterilizer are: the internal structure of the sterilizer is complicated, and the increase in manufacturing cost exceeds the improvement of the sterilizing effect obtained by it; the ultraviolet lamp is driven in a traditional way, and the limitation of the application range of the traditional ultraviolet lamp is not broken, etc.

[0007] The disadvantage of this sterilizer is that the overall volume and quality of the device are large, which is not conducive to carrying

In addition, like the above-mentioned eddy current ultraviolet sterilizer, the way of driving the ultraviolet lamp of this sterilizer is also consistent with the traditional way, without breaking through the limitation of the application range of the traditional ultraviolet lamp
