Background

At present, the sterilization and disinfection of air are generally carried out by adopting an ultraviolet irradiation method, and the method is widely applied to places such as hospitals, schools, public places, families and the like. Ultraviolet ray principle of killing organisms (bacteria, virus): ultraviolet rays with proper wavelength can destroy the molecular structure of DNA (deoxyribonucleic acid) or RNA (ribonucleic acid) in microbial organism cells to cause death of growing cells and/or regenerative cells, thereby achieving the effects of sterilization and disinfection. Because the bacteria and the viruses can be sterilized only when the ultraviolet ray absorption dose reaches a certain degree, the problem of missed sterilization is often caused by insufficient ultraviolet ray absorption dose of the bacteria and the viruses in the process of sterilizing and disinfecting the flowing air by using the ultraviolet ray.

Detailed Description

The utility model discloses an utilize embodiment one of the device that disappears of above-mentioned method, as shown in figure 1, including disappearing and killing storehouse 1, disappear and kill storehouse 1 and have air inlet and gas outlet, its air inlet department is provided with intake pipe 4, and gas outlet department is provided with outlet duct 5. The air outlet of the sterilizing bin is provided with a partition 2 which is provided with a plurality of air holes, the aperture of each air hole is micron-sized or nano-sized, so that viruses and bacteria in corresponding air can be blocked, and the air can pass through the air holes. The pore size is selected from micron-scale or nanometer-scale and specific size, and is selected according to the size of virus or bacteria to be killed. Because bacteria and viruses have a range of sizes, the size of viruses is generally smaller than that of bacteria. The scientific community finds that in nature, the minimum size of the virus is about 40nm, for example, the size of the new coronavirus is about 120nm, and if the new coronavirus in the air is to be killed, the pore diameter of the pore for separating is only required to be less than 120 nm. And the size of gas molecules such as oxygen molecules and nitrogen molecules is below 1 nm. An ultraviolet lamp 3 is arranged in the sterilizing chamber.

The sterilizing cabin in the embodiment is a single-stage sterilizing cabin. The ultraviolet lamp in the sterilizing cabin is arranged right opposite to the air hole of the partition, so that the partition 2 can be directly irradiated by ultraviolet rays. The inner wall of the sterilizing bin is also provided with a metal reflecting layer for reflecting ultraviolet rays and increasing the irradiation frequency and intensity of the ultraviolet rays. The metal reflective layer may specifically be a specular aluminum layer. The air inlet pipe 4 is provided with a primary filtering device 6 for filtering dust and moisture in the air, and the primary filtering device belongs to the prior art, and the specific structure of the primary filtering device is not described in detail in the embodiment.
