Due to the small space of the carriage and the concentrated activity of the personnel, the spread of the virus can also be increased by orders of magnitude as the running time of the train is increased, thereby bringing great challenges to the prevention and control of diseases. Therefore, it is necessary to provide a disinfecting apparatus having high virus treatment efficiency in a crowded place such as a subway, a bus, and a high-speed railway carriage to reduce the propagation speed of viruses.
At present, biological and virus research institutions of various countries all over the world agree with the conclusion that ultraviolet rays in special wave bands can radiate the air containing new coronavirus, so that the human coronavirus can be effectively inactivated. The selected indoor air disinfector for the coronavirus needs three elements and necessary conditions for inactivating the coronavirus; 1. ultraviolet light source of special wavelength band. 2.

In addition, because the euv light source can have an injurious effect on human skin and eyes in a relatively closed space, the uv light source must be shielded and isolated from leakage.
Meanwhile, the photocatalyst is used for catalyzing the titanium dioxide coating to generate hydroxide particles by utilizing ultraviolet light radiation (light wave is 253.7nm) on the coating with the titanium dioxide material to play a role in sterilization and disinfection so as to effectively eliminate and decompose dust, various harmful gases and various pathogenic bacteria in indoor air.
