Problems solved by technology

[0002] At present, the conventional technology for sterilizing air, especially the air in the air duct, is to use a single technical means such as high-efficiency filtration, ozone, ultraviolet light irradiation, spraying chemical reagents such as formaldehyde, photocatalyst, negative ions, plasma, etc. The combination of these technologies is used to sterilize and disinfect the air, but some of these technical means are more complicated in structure, some of them are not ideal, and some of them will produce side effects.

Embodiment Construction

[0022] like figure 1 Shown, the non-filter type air sterilization method of the present invention is made up of following steps:

[0023] A. Add negative ions to the air to be sterilized and mix evenly, wherein the concentration of negative ions in the air after mixing is not less than 50 / cm 3 Air, the water content in the mixed air is not less than 2.0 g / Kg dry air at a standard atmospheric pressure;

[0024] B. Treated by ultraviolet light irradiation and / or catalyst.

[0025] Because negative ions in the air are mainly negative oxygen ions O 2 - form, when there is enough moisture in the air, the negative oxygen ion O 2 - It will combine with water to form hydrated negative ions [O 2 - (H 2 O) n ]. The hydrated negative ions in the air will quickly react to generate hydroxyl OH under the excitation of ultraviolet light irradiation. Because hydroxyl is a very oxidizing oxidant, it can quickly kill bacteria and viruses in the air; if the hydrated negative ions are u...

Abstract

A non-filtering air sterilization method includes: A. adding negative ions into the air for sterilization and mixing uniformly, the negative ion concentration in the mixed air is not less than 50 units / cm3, and the water content of the mixed air is not less than 2.0g water per kg dry air under one standard atmosphere; B. treating with ultraviolet radiation and / or catalyst. A non-filtering air sterilization device, includes: a wind channel with inlet and outlet, along which air is forcibly directed in one direction, a mixing zone for negative ions and vapor, and ultraviolet radiation and / or catalyst treatment zone set in the wind channel along the air flow direction. The sterilization method and device use negative ions and water to produce hydrated negative ions, which, under the effect of ultraviolet radiation and / or catalyst, produce hydroxide radical having oxidizing properties, said hydroxide radical killing bacteria and virus in the air quickly and effectively.

Description

technical field [0001] The invention belongs to the technical field of air sterilization, and in particular relates to a non-filtering air sterilization method and a non-filtering air sterilization device. Background technique [0002] At present, the conventional technology for sterilizing the air, especially the air in the air duct, is to use a single technical means such as high-efficiency filtration, ozone, ultraviolet light irradiation, spraying chemical reagents such as formaldehyde, photocatalyst, negative ions, plasma, etc. The air is sterilized and sterilized by the combination of these techniques, but some of these technical means are implemented with complex structures, some effects are not ideal enough, and some have side effects. Contents of the invention [0003] The purpose of the present invention is to provide a non-filtering air sterilization method which is simple and effective and has obvious sterilization and disinfection effects. [0004] Another obj...
