Novel air filter

Abstract

The invention discloses a novel air filter. The peripheral air inlet manner of an air filter body is adopted for air inlet, when air passes through a filter net layer, the filter net layer will intercept impurities like large-particle dust, when the air passes through a ventilation pipeline mounted in the filter body, an LED deep ultraviolet lamp mounted in the axis of the ventilation pipeline sends out ultraviolet to the periphery of the ventilation pipeline, and has the oxidizing reaction with photocatalysts on the periphery of the inner wall of the ventilation pipeline, various bacteria, germs and volatile gas with the molecular diameter as the nanoscale can be decomposed, and the novel air filter can be used for destroying regeneration capacity of harmful microbes and removing harmful gas of dioxin, formaldehyde, benzene and the like and has the beneficial effects of being short in sterilization time, free of mercury and side effect, wide in use range, capable of being mounted on an air conditioner air outlet of a mansion, an air inlet of civil air defense engineering, a purification processor of automobile tail gas and various air purifier devices.

Description

technical field [0001] The invention relates to the field of LED deep ultraviolet light irradiation and photocatalyst oxidation reaction, and more specifically relates to a novel air filter. Background technique [0002] Both air and water are the source of life, which nourishes all things and feeds life. Contemporary China, which is in a period of social transformation, is facing numerous environmental pollution problems, among which air pollution is particularly prominent. The deterioration of the air has forced people to face this serious problem, and it is expected that the natural environment will be difficult to improve for a long time. [0003] Everyone knows that in polluted air, there are more than four types of harmful microorganisms that need to be eliminated. The first type is various solid suspended solids and particles with a diameter of less than 100um; the second type is various bacteria, microorganisms, viruses, and bacteria The diameter of some viruses is...

AI Technical Summary

Problems solved by technology

The PM2.5 we often say does not specifically refer to a certain type of air pollutant, but all particles with a particle diameter below 2.5um. In addition, bacteria and viruses will be adsorbed on such particles. PM2.5 does not include volatile However, the volatile gas and smoke are not less harmful to the human body than PM2.5. At present, it is easy to intercept the diameter particles such as dust and ash, and only need to use a simple ordinary filter , however, for substances above PM2.5, especially volatile gases such as formaldehyde, benzene, and dioxin, there is currently no good means to effectively remove them

[0004] Traditional air purifiers generally use multi-layer filter settings to intercept to achieve disinfection and purification of the air, but with this treatment process, the effect is not great, only PM2.5 can be intercepted, for the other three types above of harmful microorganisms are completely impossible to eliminate

[0005] In addition, the UV light produced by the high-pressure mercury lamp ultraviolet sterilization equipment looks very bright, high in heat, large in size, large in power consumption, and wide in spectrum. The ultraviolet spectrum that is really effective in sterilization and disinfection only accounts for a part of its energy. A considerable part of the heat is generated in the visible light segment. Although the total output power of traditional UV mercury lamps or UV mercury lamps is large, the output of deep ultraviolet light per unit area is very weak, only a few hundredths of deep ultraviolet light emitting diodes with a wavelength of 260nm to 280nm.

Because mercury gas is produced during high-pressure mercury work, which is not friendly to the environment, it will cause secondary pollution, and the effect will not reach the effect of disinfection and sterilization
