an ultraviolet generator

Abstract

The invention discloses an ultraviolet generator, which belongs to the field of optoelectronic technology, and comprises a body and a fixed bracket arranged on the upper end of the body, wherein the body is a closed cavity made of quartz glass tube, with a through hole in the middle, and the cavity is filled with There are one or more mixtures of argon, krypton, xenon, neon, and Kr85. The two ends of the body are symmetrically equipped with magnetic rings. The top of the magnetic ring is equipped with an induction coil. It is connected with the high-frequency generator; the main body is provided with an amalgam containing chamber which communicates with the sealed cavity of the main body. When the above-mentioned ultraviolet generator is working, the gas and mercury vapor in the ionization chamber are induced by the magnetic ring, and the mercury vapor releases ultraviolet rays, which solves the problem of short service life due to the loss of the emitting material; and because there is no sputtering of the emitting material, the cavity is solved. In order to solve the problem of internal pollution, the maintenance rate of the spectral energy emitted by ultraviolet rays has been greatly improved.

Description

technical field [0001] The invention relates to an ultraviolet generator and belongs to the field of photoelectric technology. Background technique [0002] Ultraviolet is the general term for radiation with wavelengths from 10nm to 400nm in the electromagnetic spectrum. According to wavelength, it can be divided into: near ultraviolet (UVA), far ultraviolet (UVB) and ultra-short ultraviolet (UVC). Ultraviolet rays can ionize oxygen in the air to generate oxygen free radicals and ozone, both of which have strong oxidizing effects and can be used for fast curing of glue in the chemical industry and printing industry. Far ultraviolet (UVB) with a wavelength of 253.7nm can break the replication ability of DNA to produce proteins. After the DNA and RNA of bacteria and viruses are damaged, their protein production ability and reproductive ability have been lost. Because bacteria and viruses generally have a short life cycle, they cannot reproduce bacteria, and the virus will die...

Problems solved by technology

[0003] At present, the commonly used ultraviolet generating device adopts electrode emission, which has problems such as large material loss, easy sputtering of consumables in the cavity, and large pollution; in addition, the working life of the current ultraviolet generator is not long, because the ultraviolet lamp is in the working process. In the process, the material itself will be exposed to ultraviolet radiation, and the material will age quickly and the product will be damaged; moreover, as the material of the ultraviolet generating device ages, its transmittance will also decrease, which will affect its performance, resulting in that the amount of ultraviolet rays in the later period cannot be achieved. fulfil requirements
