Abstract

The invention relates to an ultraviolet water purification apparatus, which comprises disinfection pipes (1) using quartz glass, and UVC LED assemblies (2), wherein the UVC LED assemblies (2) are arranged at both port walls (10) of the disinfection pipe (1), one of the outer pipe wall and the inner pipe wall of the disinfection pipe (1) is a reflecting surface (12), the other one of the outer pipewall and the inner pipe wall of the disinfection pipe (1) is a light emitting surface (11), the reflecting surface (12) comprises a roughening layer (121) formed by patterning treatment, and an aluminum reflecting layer (32) is plated on the roughening layer (122). According to the present invention, by utilizing the high transmittance of light in the high purity SiO2 glass, the optical travel ofthe UVC in the killed fluid is minimized so as to avoid the light attenuation of UVC.

Description

technical field [0001] The invention relates to an LED UVC (short-wave ultraviolet light) device for disinfecting bacteria and viruses. Background technique [0002] Deoxyribonucleic acid (DNA), ribonucleic acid (RNA) and nucleoproteins in bacteria have the strongest ultraviolet absorption peaks at 254-257nm. After the bacteria absorb ultraviolet light, it will cause the DNA chain to break, cause the cross-linking of nucleic acid and protein to break, kill the biological activity of the nucleic acid, and cause the death of the bacteria. When the radiation intensity reaches 30mW / cm2, bacteria and viruses are killed within 10s. Quick and convenient, because of the characteristics of no physical contact and no secondary pollution, the application of UVC in the field of sterilization has great advantages and is widely used. [0003] The mainstream of the UVC light source currently used is a low-pressure mercury lamp, which is limited in many applications due to its mercury c...
