Mingrui Optoelectronics:provides a UVLED germicidal lamp device

Mingrui Optoelectronics The invention belongs to the technical field of water treatment and provides a UV LED germicidal lamp device. The UV LED germicidal lamp device comprises an electric control box, a water purification shell is fixedly mounted on the electric control box, a transparent quartz glass tube is hermetically and fixedly mounted in the water purification shell, a water sterilization chamber is formed between the transparent quartz glass tube and the water purification shell, two ends of the water purification shell are respectively provided with a water inlet and a water outlet communicated with the water sterilization chamber, and a UVC lamp tube is also detachably mounted on the water purification shell. The UVC lamp tube is located in a transparent quartz glass tube.

According to Mingrui, the invention can achieve rapid sterilization of still or flowing water bodies. The sterilization process will not introduce impurities into the water body. The physical and chemical properties of water remain unchanged. Overtreatment will not cause the problem of water quality decline. The sterilization range is wide and rapid. It takes only ten seconds to kill pathogenic microorganisms. It can also control the growth of some higher-level aquatic organisms to a certain extent, achieving efficient spectral sterilization and killing almost all bacteria and viruses efficiently.

ams Osram:Device and method for disinfecting fluids flowing through it

Recently, ams Osram disclosed a device (10) for disinfecting fluids flowing therethrough by UV radiation (UV reactor), the device (10) comprising a container (20) having an inlet (22) for receiving the fluid and an outlet (24) for discharging the fluid from the container (20), a variable or adjustable irradiation zone (12) for irradiating the fluid with UV radiation being provided within the container (20). The irradiation zone (12) is designed as a gap extending between two oppositely disposed reactor walls (14,26) and fluid flows through the gap.

It is possible to vary the mutual distance (D) between the reactor walls (14,26), and thus the gap size (D) of the gap, by designing at least one reactor wall (14) to be movable. Ames Osram describes that the movable reactor wall (14) is the wall of a displaceable body (9) located inside or protruding into the vessel (20). By adjusting the distance between the reactor walls (14,26) in the area of the irradiation zone (12) in the form of a gap and thus adjusting the layer thickness (D) of the fluid flowing through the gap, the operating efficiency of the UV reactor (10) is optimized at different scattering and absorption properties of the fluid. Optionally, a sensor (7) is used to detect the penetration depth of radiation and adjust the gap size (D) based on the sensor signal.
