Description

Silk screen type 222nm excimer sterilizing lamp

Technical Field

The utility model belongs to the technical field of the disinfection of disinfecting and specifically relates to a silk screen type 222nm excimer lamp.

Background

Water and air are important resources for human beings, and water pollution and air pollution become more serious with the development of industry. However, the living standard of people is continuously improved, the requirements on living environment are higher and higher, and disinfection and sterilization are an important aspect. The ultraviolet germicidal lamp is a widely used disinfecting and sterilizing device, belongs to a low-pressure mercury lamp, and is excited by using lower mercury vapor pressure (less than 10-2Pa) to emit ultraviolet light, and the main two emission spectral lines are as follows: the first is 253.7nm wavelength; the other is 185nm wavelength, the two ultraviolet rays cannot be seen by naked eyes, the ultraviolet rays do not need to be converted into visible light, and the 253.7nm wavelength can play a good sterilization effect because the cells have a rule on the absorption spectral line of light waves and have the maximum absorption rate on the ultraviolet rays of 250-270 nm. The medicine proves that the absorbed ultraviolet light actually acts on cell genetic material, namely DNA, and plays a photochemical role, and the energy of ultraviolet photons is absorbed by base pairs in the DNA to cause the genetic material to be mutated, so that the bacteria die immediately or cannot reproduce offspring, thereby achieving the aim of sterilization.

The traditional ultraviolet germicidal lamp emits limited spectral lines or spectral bands, and cannot meet various requirements in the fields of photochemistry and photobiology, and the excimer can provide more than 20 spectral lines, so that the ultraviolet germicidal lamp is an effective supplement of the traditional ultraviolet germicidal lamp. For example, 253.7nm radiation from a low-pressure mercury lamp is completely ineffective in removing chlorinated ester compounds, only 222nm narrow-band radiation of an excimer can be used, and the 222nm excimer can be used for photooxidation of vinyl chloride and some saturated chlorinated hydrocarbons, and has good effects on water treatment and air purification lamps.

Therefore, the company develops the first 222nm excimer and sells the excimer on the market, the copper wire is wound outside the existing 222nm excimer, each circle of copper wire is fixed through soldering tin and then is connected with a cable, the process needs manual winding on the copper wire, the manual workload is a little large, the efficiency is low, the copper wire is easy to break, and the requirement on workers is higher; in addition, when the finished product is used, the copper wire is easy to break, and the using effect is influenced. In order to solve the problem, it is necessary to develop an excimer lamp which can increase the working efficiency in the manufacturing process, has high reliability and long service life.
