    摘要: Provided is a photocatalyst unit that can improve the fluid cleaning action using a photocatalyst by efficiently applying ultraviolet light to a photocatalyst, and at the same time, that can, as a photocatalyst unit including a photocatalyst filter and a light application part, be reduced in thickness and size, and that has a high degree of freedom in design of a flow path structure.
    A photocatalyst carrier 3 is an impeller 4 including a plurality of vane plate parts 41 each of which has a surface carrying a photocatalyst, and the plurality of vane plate parts 41 rotate upon receiving a pressure from a fluid passing through a fluid passage path 10. A light application part 5 is provided so as to apply light to the rotating vane plate part 41 of the impeller 4, from a predetermined position on an outer circumferential side with respect to the vane plate parts 41 of the impeller 4.

    摘要: A system and method for sterilizing recirculated airflow in closed environments, as well as certain types of material equipment includes electronically steered antenna (ESA) elements. The ESA elements operate in radio frequencies (RF). The ESA elements produce directed beams of microwave radiation to sterilize surfaces or volumes of air. The directivity gain associated with the beam forming increases RF energy density in the area where the beam is steered.

    摘要: An air sterilization apparatus, comprising: a main housing (100). A cavity (101) for air circulation is provided in the main housing (100). The cavity (101) is provided with an air inlet (102) and an air outlet (103). The air inlet (102) and the air outlet (103) each is provided with a joint. A pulse flashing unit (300) is provided in the cavity (101). The pulse flashing unit (300) comprises a charging circuit (301) connected to an external power supply. A current output by the charging circuit (301) sequentially passes through a capacitor (302) and a discharging circuit (303), and is then input into an inert gas bulb (304). Strong light emitted by the pulse flashing unit (300) kills bacteria in air. No chemical residues would be produced, and the sterilization efficiency is high.
