Photomagnetic oxidation disinfection device and method

Abstract

The invention discloses a photomagnetic oxidation disinfection device and method. The device comprises an air inlet and an air outlet, and further comprises a magnetic oxygen cavity and a photomagnetic catalysis cavity, wherein the magnetic oxygen cavity is communicated with the photomagnetic catalysis cavity, and the air inlet and the air outlet are formed in the magnetic oxygen cavity and the photomagnetic catalysis cavity respectively; the magnetic oxygen cavity enhances the concentration of negative ions through a magnetic field, and air entering from the air inlet is disinfected once in combination with ozone; and the optomagnetic catalysis cavity promotes hole electron separation through the magnetic field, so that the photocatalytic efficiency is improved, and air entering from the magnetic oxygen cavity is subjected to photocatalytic secondary disinfection and killing. The invention aims to perform secondary sterilization on external polluted air by introducing the magnetic field to achieve synergistic effects of the magnetic field and negative ions and the magnetic field and photocatalysis so as to realize up-to-standard emission of the air; and the device is small and exquisite, can comprehensively and efficiently sterilize various bacteria in the air in a dynamic sterilization process, and achieves the purpose of man-machine coexistence.

Description

technical field [0001] The invention relates to the technical field of disinfection and disinfection, in particular to a photomagnetic oxidation disinfection device and method. Background technique [0002] At present, there are static disinfecting and dynamic killing for disinfection and disinfecting. Static disinfecting uses methods such as spraying disinfectant or releasing ozone. This method is only suitable for disinfecting when the place is empty and no one is there; Disinfection equipment kills places where people are active, and at the same time, it must ensure that the disinfection process is harmless to the human body. The dynamic disinfecting process belongs to the coexistence of man and machine. At present, the commonly used technical means include fiber filter material filtration, electrostatic, ultraviolet light, ultraviolet photocatalysis and other methods. These single technical means have a slow rate of disinfecting germs, which restricts the need for rapid d...
