The ultraviolet disinfection device is a disinfection equipment that uses UV-C ultraviolet light (wavelength 253.7nm) to destroy the DNA structure of microorganisms to achieve sterilization. It is widely used for sterilization of water bodies, air, and object surfaces.
一、 Main types
1. Closed system
Suitable for small and medium-sized water treatment, using stainless steel or aluminum alloy reactors with polished inner walls to enhance ultraviolet reflection.
Divided into parallel and vertical lamp tube layouts, the latter improves sterilization efficiency through turbulent flow.
2. Open system
Immersion type: The ultraviolet lamp is placed in water and has a high utilization rate of radiation energy, making it suitable for sewage treatment.
Water surface type: UV lamps are installed above the water surface, with low efficiency and limited application.
3. Open channel type
Used for municipal or industrial wastewater treatment, supporting components such as gates and rectifier grilles, and supporting buried or semi buried installation.
二、 Application Fields
Water treatment: including municipal water supply, industrial circulating water, swimming pools, and seawater desalination.
Medical environment: Hospital water and equipment disinfection.
Household scenario: Disinfection of items such as toothbrushes and cutting boards (note the limitations of UV penetration).
