Embodiment Construction
[0015] The present invention will be further described below in conjunction with accompanying drawing, and the structure and principle of the present invention are very clear to those skilled in the art. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0016] The present invention adopts 172nm excimer lamp, and concrete reaction equation is as follows:
[0017] 1.O 2 →O 3 →O 2+ ;
[0018] 2.C x h y o z →C m h n o k (x>m,y>n,z>k);
[0019] In summary: C m h n o k +O 2+ / O 3 →CO 2 +H 2 O+CO.
[0020] It can be seen from the above that the change of ozone concentration has a significant impact on the effect of the excimer lamp.
[0021] The principle is as follows: After ultraviolet rays irradiate the solid surface, the organic molecules of the pollutants on the surface are cut off by the strong light energy, oxidized, and then decomposed into volatile sub...

Abstract
The invention relates to the technical field of sterilization and deodorization, in particular to a light intensity and ozone concentration control device for excimer lamps. The device comprises an excimer lamp box, and a plurality of excimer lamps are arranged in the excimer lamp box. The device is characterized in that one end of the excimer lamp box is connected with a nitrogen filling port, the other end of the excimer lamp box is connected with a nitrogen outlet, a base material is arranged in the excimer lamp box and arranged on the outer side of a closed cavity, and the device further comprises a PLC control device which is connected with a nitrogen conveying device through a signal line. The device has the advantages that the excimer lamps and oxygen in the air are subjected to photochemical reaction to generate ozone, and the concentration of the ozone can be controlled by introducing nitrogen, so that the ozone concentration is kept at the optimal concentration.
Description
technical field [0001] The invention relates to the technical field of sterilization and deodorization, in particular to a light intensity and ozone concentration control device for an excimer lamp. Background technique [0002] Ozone (O3), which has a strong oxidizing power, can be used for sterilization and deodorization. Moreover, as a method for generating ozone, there are known a discharge method and a photochemical reaction method. Ozone is generated by silent discharge such as creeping discharge, and the photochemical reaction method is to generate ozone by irradiating ultraviolet rays to ozone source gas. [0003] There is a patent for invention: processing method, patent number: 2018800125427, which is to obtain ozone-containing gas by irradiating ozone source gas with light that does not contain the wavelength region that decomposes ozone, and that is light with a wavelength of 200 nm or less for ozone generation. Gas: The object to be processed is processed by e...
