Air purification and purifier under ozone ultraviolet radiation

Abstract

This invention provides a kind of ozone environment ultraviolet radiation air purifying method. It includes at least one ultraviolet generating device and an ozone-generating device. The ultraviolet generating device generates ultraviolet to purify air. The ozone-generating device generates or stores ozone and discharge the ozone into the said ultraviolet radiated air. The air-purifying device using the said method includes the ultraviolet generating device and the ozone-generating device. This invention can instantly purify air and has evident sterilizing and disinfecting effect.

Description

technical field [0001] The invention relates to air purification technology, in particular to a method and device for purifying air in real time and killing harmful microorganisms such as viruses or germs in the air by using ozone and ultraviolet radiation. Background technique [0002] In the current large buildings, various construction, decoration materials and furniture will release harmful gases such as formaldehyde, benzene or ammonia, which have toxic and side effects on the human body, and office equipment such as copiers and fax machines will also produce certain harmful gases. , in order to eliminate harmful gases in the building, it is necessary to communicate with the outside world. Although all kinds of large-scale central air-conditioning equipment generally have the function of exchanging fresh air, in order to reduce the energy consumption of the air conditioner, the amount of fresh air added generally does not exceed its 30%-40% of the total air volume, so t...

Problems solved by technology

It takes 30 minutes to kill the bacteria by irradiating the stagnant gas with 254 nanometer spectral line ultraviolet light (equivalent to 3.3-3.6eV). The mechanism of action is that the covalent bonds of organic molecules that make up the bacterial cytoplasm can be broken under ultraviolet irradiation, but The free radicals produced after the covalent bond is broken have a tendency to recover, so the bactericidal effect is poor if it is completely relying on ultraviolet radiation. The same principle, harmful gases in the air can also break the covalent bond under the irradiation of ultraviolet light. However, Broken covalent bonds have a tendency to recover, so only using ultraviolet radiation to purify the air, the effect and efficiency of sterilizing and purifying the air are very low

For existing air-conditioning equipment such as large-scale central air conditioners, in order to save energy and materials, the setting of the air duct cannot be too large, and the speed of the airflow must also maintain a certain rate, which restricts the residence time of the air in the air duct , so it is difficult to achieve good purification and sterilization effects only by ultraviolet radiation
