Embodiment 1

[0032] like Figure 1 ~ Figure 2 As shown, this embodiment provides a photocatalytic disinfecting device for viruses on the surface of articles, including an atomization chamber 1, a disinfecting chamber 2 with an ultraviolet lamp, and a conveying mechanism for transporting articles to be sterilized. Chamber 1 and disinfecting chamber 2, the atomization chamber 1 is provided with an atomization mechanism for spraying a photocatalytic atomizer on the surface of articles to be sterilized.

[0033]Take the packaging box 9 as an example of the article to be sterilized. When in use, the packaging box 9 is placed on the conveying mechanism, and driven by the conveying mechanism, it first enters the atomizing chamber 1, and the atomizing mechanism in the atomizing chamber 1 puts the light The catalyst is atomized and sprayed on the surface of the packing case 9 to form a layer of photocatalyst film on the surface of the packing case 9, and then the packing case 9 with the photocatalyst...

Embodiment 2

[0050] This embodiment also provides a method for photocatalytic disinfecting of viruses on the surface of articles, comprising the following steps:

[0051] 1) Use the conveying roller 3 to send the article to be sterilized through the fog shield 5 and then into the atomization chamber 1, and spray the atomized photocatalyst on the surface of the article to be sterilized by the atomization spray gun in the atomization chamber 1, and at the same time, the The atomizing spray gun below the conveying roller 3 sprays the photocatalytic atomizer on the bottom surface of the article to be sterilized through the gap between adjacent conveying rollers 3, forming a photocatalyst film on the surface of the sterilized article, and the article to be sterilized leaves the atomization chamber 1 and enters the transition chamber;

[0052] 2) The article to be sterilized leaves the transition chamber and enters the disinfecting chamber 2. In the disinfecting chamber 2, the ultraviolet rays pa...

Abstract

The invention discloses a photocatalytic disinfection and killing device and a disinfection and killing method for viruses on the surface of an article, and relates to the technical field of sterilization and disinfection equipment. The device comprises an atomization cavity, a disinfection and killing cavity internally provided with an ultraviolet lamp, and a conveying mechanism used for conveying the article to be disinfected; the conveying mechanism sequentially penetrates through the atomization cavity and the disinfection and killing cavity; and an atomizing mechanism for spraying a photocatalytic atomizing agent to the surface of the article to be disinfected is arranged in the atomization cavity. The atomization cavity is formed, the atomization mechanism for spraying a photocatalyst to the surface of a packaging box is arranged in the atomization cavity, a photocatalyst film can be formed on the surface of the packaging box, and the surface of the packaging box can be effectively disinfected in combination with irradiation of the ultraviolet lamp; and the long-acting virus inhibition and inactivation effect is maintained in the subsequent transportation link, so that viruses are well prevented from being spread through the packaging box or other food packages, the safety of food transportation is ensured, and an effective guarantee is provided for the health of the masses.

Description

technical field [0001] The invention relates to the technical field of sterilization and disinfection equipment, in particular to a photocatalytic disinfecting device and a disinfecting method for viruses on the surface of articles. Background technique [0002] The outer packaging surface of virus-contaminated food has been transported through the cold chain, which has become a hidden route for virus transmission. It is easy to cause infection of people in contact with it. Infection cases occur from time to time. How to effectively control the virus contamination of cold chain food to ensure food safety and Protecting people's lives is an urgent task for scientific and technological workers. Resolutely prevent the spread of viruses through cold chain logistics channels, timely control and eliminate virus safety hazards in cold chain logistics, and there is a great demand for the development of efficient and safe virus elimination technology on the outer packaging surface of...
