    Abstract: A solution for irradiating a flowing fluid through a channel with ultraviolet radiation is provided. Ultraviolet radiation sources can be located within the channel in order to direct ultraviolet radiation towards the flowing fluid and/or the interior of the channel. A valve can be located adjacent to the channel to control the flow rate of the fluid. A control system can control and adjust the ultraviolet radiation based on the flow rate of the fluid and a user input component can receive a user input for the control system to adjust the ultraviolet radiation. The ultraviolet radiation sources, the control system, the user input component, and any other components that require electricity can receive power from a rechargeable power supply. An electrical generator located within the channel can convert energy from the fluid flowing through the channel into electricity for charging the rechargeable power supply.

    Abstract: [Problems]
    To implement UVC energy irradiation at a unified amount to a target for sterilization and decomposition of all in a fluid that is flowing, by greatly increasing a depth of a fluid that receives radiation from a UVC light source significantly to increase a rate at which UVC energy per unit irradiates the target of sterilization and decomposition in the fluid, in continuous sterilization of fluids by UVC irradiation in a container optically shielded from the outside.
    Means for Solving the Problem
    In order to allow the entire fluid flowing into the container to flow out of the container with the same in-container movement time, the container is equipped with one or a plurality of bulkheads composed of highly UVC permeable material at an angle to receive a maximum radiation from the UVC light source; an opening at one end through which the fluid passes is disposed to be positioned at an end of an opposite side mutual next to the other thereby allowing the fluid flowing into the container to flow in layers along the bulkheads; bending one after the other from the openings in the bulkheads to further flow layers forms a series of overlapping flow layers over the entire area of the container, irradiating the UVC through these layers.

    Abstract: This disclosure is related to an ultraviolet fluid sterilizing box structure. A box (10) includes a chamber (100), a water inlet (101) and a water outlet (102). The water inlet (101) and the water outlet (102) are located on different sides of the box (10). The partition (20) is disposed in the chamber (100) and includes an outer cylinder (21) and an inner cylinder (22). The outer cylinder (21) includes an outer cavity (210) and an inflow inlet (211). The inner cylinder (22) includes an inner cavity (220) and an opening (221). The ultraviolet module (30) is disposed on one side of the box (10) and includes a light-transmitting plate (31) and an ultraviolet lamp set (32). The light-transmitting plate (31) seals the outer cylinder (21). The ultraviolet rays irradiate the inner cavity (220) and the outer cavity (210).

    Abstract: A device for disinfecting a fluid includes a first casing and a second casing. Each casing includes at least one source of UV radiation. A fluid passage is provided between the first casing and the second casing. The UV radiation emitted from the at least one source of UV radiation of the first casing is emitted in a first direction toward the fluid passage. The UV radiation emitted from the at least one source of UV radiation of the second casing is emitted in a second direction toward the fluid passage. The first direction is different than the second direction.

    Abstract: A collimation type disinfection and water purification device includes a reactor cavity. The reactor cavity is in a linear shape extending in a front side direction and a rear side direction. A water inlet and a water outlet are respectively formed in side walls of a front side and a rear side of the reactor cavity. Ultraviolet (UV) modules are arranged at end parts of the reactor cavity. The UV module includes a radiation component and a Total Internal Reflection (TIR) lens. The radiated UV light can enter the reactor cavity in a collimation manner by using a design that the radiation component is matched with the TIR lens, which improves the disinfection efficiency.
