Problems solved by technology

The temperature has a great influence on the spectrum of the electrodeless lamp. The increase of temperature will weaken the short-wavelength light intensity and increase the long-wavelength light, which will reduce the inactivation effect of ultraviolet light on bacteria and viruses.

Embodiment 1

[0029] Embodiment 1. Promise ultraviolet light source air cleaning and sterilization method

[0030] The infinite ultraviolet light source air cleaning and sterilization method is mainly used for the inactivation of bacteria and viruses in the air and the removal of gaseous pollutants such as formaldehyde, benzene, TVOC, etc. removal of pollutants. The method is as follows: by controlling the microwave power controller to output high voltage, the magnetron is excited to emit microwaves with a frequency of 2450 MHz and a power of 800 watts. After the microwave enters the reactor, it combines with the oxygen in the air to be treated to generate ozone. Ozone acts on the treated air to inactivate the bacteria and germs in it. Finally, the coating on the net is cleaned through the air outlet to further reduce the germs contained in the air. It should be noted that when the air to be treated flows through the electrodeless illuminant, on the one hand, the temperature of the air f...

Embodiment 2

[0037] Embodiment 2. Promise ultraviolet light source air cleaning and sterilization equipment

[0038] The infinite ultraviolet light source air cleaning and sterilization equipment is a completely independent air cleaning and sterilization system, which can be directly placed in any place to be applied. The structure of the device is as figure 1As shown, it includes air inlet fan 1, air inlet filter 2, excitation cavity housing 3, excitation cavity 4, microwave controller 5, exciter 6, electrodeless illuminant 7, illuminant fixing bracket 8, and air outlet filter 9 , shell 10. Wherein: the air inlet fan 1 is installed at the bottom of the excitation chamber 4, and sucks the air to be treated. The air inlet filter screen 2 is located at the air outlet of the air inlet fan 1 to filter out air impurities. The excitation cavity 4 is located on the upper part of the filter screen 2 of the air inlet, and the two form a compact fit to ensure that the microwave in the excitation ...

Abstract

The invention relates to an electrodeless UV (Ultraviolet) source air cleaning and sterilizing method and device. The electrodeless UV source air cleaning and sterilizing method comprises the following steps: introducing the air to be sterilized from an air intake, filtering physical impurities in the air by virtue of a filter screen at the air intake, and then, enabling the filtered air to enter into an excitation chamber; meanwhile exciting a magnetron by a microwave controller to send out microwaves, and enabling the microwaves to enter into the excitation chamber through an exciter; and sending out UV light with the wavelength of 254-280nm by molecules in an electrodeless luminophor in the excitation chamber under the action of the microwaves, generating ozone under the combined action of the UV light and the ozone in the air, inactivating bacteria and virus in the air of the excitation chamber, and exhausting the processed air through the filter screen at the air intake. The electrodeless UV-light source air cleaning and sterilizing device comprises an air inlet fan, an air inlet filter net, the excitation chamber, the microwave controller, the exciter, the electrodeless luminophor, and the air outlet filter net. The electrodeless UV source air cleaning and sterilizing device can be used for inactivating the bacteria in the air and eliminating gaseous pollutants including formaldehyde, a TVOC (total volatile organic compound) and benzene, and has the advantages of high air purification rate, short processing time and the like.

Description

technical field [0001] The invention belongs to the technical field of air purification, sterilization and disease prevention, and in particular relates to an air cleaning and sterilization method and equipment of an infinite ultraviolet light source. Background technique [0002] Water and air are important conditions for human survival. With the rapid economic development and population increase, our living environment is gradually deteriorating, and some diseases caused by polluted air are increasing. How to effectively improve indoor air quality, eliminate germs in the air, and reduce indoor toxic and harmful residues (such as formaldehyde, benzene, TVOC and other gaseous pollutants) has become a common concern of people. [0003] Ultraviolet light, especially short-wavelength ultraviolet light, has a special effect on air sterilization. It is an effective bactericidal spectrum widely recognized by people, and there are a large number of application examples of ultravio...
