In-pipe laser efficient disinfection and sterilization device and in-pipe laser disinfection method

Abstract

The invention discloses an in-pipe laser efficient disinfection and sterilization device and an in-pipe laser disinfection method, and the in-pipe laser efficient disinfection and sterilization device comprises a pipeline module which is internally used for bearing a water body; a transparent window is formed in the pipeline module; the laser emission module is located at the position of the transparent window, and laser beams emitted by the laser emission module enter the pipeline module through the transparent window; and the reflection module is arranged in the pipeline module, the laser beam irradiates on the reflection module, and the laser beam is continuously reflected in the pipeline module to disinfect the water body under the reflection of the reflection module. A laser beam is emitted through the laser emission module, the laser beam has the high energy characteristic, and the laser beam is continuously reflected in the pipeline module under the reflection of the reflection module to disinfect and sterilize the water body. Moreover, the adjustment of laser parameters can be realized through the laser, and the application range is wide. And the device is compact in structure and can be well applied to a single pipeline or a pipe network.

Description

technical field [0001] The invention relates to the field of laser disinfection and sterilization, in particular to an in-tube laser efficient disinfection and sterilization device and an in-tube laser disinfection method. Background technique [0002] At present, when water plants or sewage treatment plants sterilize water bodies, chemical sterilization is usually used for sterilization. Although this chemical disinfection method can remove bacteria in the water body, it will leave a large amount of free residual chlorine in the water body, resulting in peculiar smell in the water body and affecting the use. A variety of research results also show that free residual chlorine in tap water is harmful to human body, and the use of chemical disinfection has the possibility of environmental pollution. Therefore, it is necessary to find a safer device and method for sterilizing and sterilizing the inside of the water pipe network or the pipe network of the sewage treatment plant...

AI Technical Summary

Problems solved by technology

There are many kinds of light wavelengths output by mercury lamps. The energy of light in the effective sterilizing wavelength range is extremely low, and the light attenuates significantly during the propagation process, and mercury is poisonous, which poses a safety hazard; xenon lamps and ultraviolet LED lamp beads emit divergent light. The light energy is low, the propagation distance is short, and the waste of energy is serious

Since the ultraviolet light emitted by the above-mentioned ultraviolet sterilizing light source has defects such as low energy and scattering, the sterilization efficiency is low
