[0037] Example

[0038] The designed and implemented deep ultraviolet wavelength LED lamp adopts UVC LED. The light-emitting angle of the UVC LED lamp bead is 60°, the wavelength is 275nm, and the irradiation area is equal to 400cm2. It uses a 10*10 array, the lamp bead spacing is 22~23mm, and the work is 50~60mm Distance, the system efficiency is: 70%, according to each lamp bead working at 70% of the maximum current, the output power is 7mw, the illuminance per unit area of ​​the irradiation surface of the target object with a linear distance of 50mm is: 1.225mw / cm 2 .

[0039] see figure 1 and figure 2 , UVCLED light source is lamp beads 2 with a light exit angle of 60 degrees, arranged at the cross line 1 of the aluminum substrate, the lamp beads work together to ensure that the uniformity of the light source in the 50mm irradiation area reaches 100%, and the energy density when working at full load is measured. 2.4mW / cm 2 , the calculation formula of the average opti...

Abstract

The invention discloses an in-vitro new coronavirus optical disinfecting and sterilizing method capable of realizing man-machine coexistence. The method comprises the following steps: firstly, carrying out light source type selection, design and processing according to the disinfection effect of ultraviolet light on new coronavirus aerosol; then carrying out photocatalyst type selection and designprocessing according to the characteristic that a photocatalyst net film can generate a strong oxidation reaction with viruses under the irradiation of ultraviolet light with specific wave band and energy; and finally, designing an optical disinfecting and sterilizing composite module according to the use scene of a new coronavirus disinfecting and sterilizing device, and arranging a mechanical structure for avoiding ultraviolet light leakage at the top of an air duct to ensure that people can simultaneously exist during space sterilization and disinfection. The device can be used as a core disinfecting and sterilizing module of a current air purifier and a mainstream air conditioner, and has the advantages of being controllable in cost, environmentally friendly, high in new coronavirus disinfection efficiency and capable of achieving man-machine coexistence.

Description

technical field [0001] The invention belongs to the technical field of disinfection and sterilization, and in particular relates to an in vitro optical disinfecting method for novel coronavirus that can coexist with humans and machines. Background technique [0002] The novel coronavirus belongs to the order Nesting Viridae, the family Coronaviridae, and belongs to the single-stranded RNA virus. The new coronavirus has an envelope, and the particles are round or oval, often pleomorphic, with a diameter of 60-140nm. Its genetic characteristics are significantly different from those of SARS-CoV and MERS-CoV. The current study has more than 85% homology with bat SARS-like coronavirus. So far, there is no specific drug specifically for the prevention and treatment of coronavirus, and only non-specific therapeutic interventions can prevent severe complications and reduce severe morbidity and mortality. Much of the understanding of the physical and chemical properties of corona...
