At present, exhaust gas treatment and oil fume purification equipment widely use 254nm+185nm dual-band UV lamps. Similar products on the market are uneven. NINGBO UV LIGHT brings together eight major technologies to launch a cost-effective, high-ozone-life 150W large U-shaped exhaust gas treatment ultraviolet lamp.

Ultraviolet light is a type of electromagnetic wave. When electrons in atoms transition from high energy level to low energy level, they will release excess energy as electromagnetic waves. The stronger the energy of electromagnetic waves, the higher the frequency and the shorter the wavelength. The discharge principle of ultraviolet lamps is the same as that of energy-saving lamps. They are all gas discharge lamps. During the gas discharge process, mercury vapor is excited, and the characteristics of mercury atoms are used to emit ultraviolet rays with wavelengths of 254nm and 185nm. proportional.

The 254nm ultraviolet light and the 185nm ultraviolet light are emitted at the same time after the mercury atoms are excited. The conventional ozone-free ultraviolet light with only 254nm wavelength is added with TI (titanium) in the quartz glass to filter out the 185nm ultraviolet light. The dual-band ozone ultraviolet lamp directly uses the so-called transparent quartz tube without TI.

Although the proportion of 254nm and 185nm ultraviolet rays will not change after the mercury atoms are excited, the proportion and attenuation of 185nm ultraviolet rays transmitted from the quartz glass tube wall are different depending on the selected quartz glass material and the treatment method for the quartz glass. very big. Because the shorter wavelength of 185nm ultraviolet rays has higher requirements for the selected quartz material.

The photolytic ultraviolet lamp commonly referred to on the market is the ozone lamp. The selected quartz glass is generally quartz glass with a hydroxyl content of less than 15PPM, an impurity content of less than 50MMP, and a purity of 99.9%. This material is used for general ultraviolet sterilization purposes. Ultraviolet lamps are possible, because the transmission of ultraviolet rays with a wavelength of 254nm is relatively less demanding, but the transmission of 185nm vacuum ultraviolet rays has higher requirements on materials. The real high-ozone ultraviolet lamps should use such quartz glass: hydroxyl content Less than 5PPM (actually close to 0), the impurity content is less than 20MMP, and the purity of quartz glass is 99.999%. The ultraviolet lamp made of this material is about 30% higher than the conventional ultraviolet lamp in the market. This is not the key, mainly because this kind of real high ozone quartz glass has only 20% attenuation of 185nm ultraviolet light in the life of 10,000 hours, while the conventional ozone ultraviolet lamp has 185nm ultraviolet output attenuation for three or four thousand hours of lighting, which is affected by the glass material. The impact is close to 50%! This is the main reason why the effect will be worse as it goes on.

Of course, quartz glass for high-purity and high-ozone ultraviolet lamps is twice as expensive as ordinary quartz glass, and it needs to be customized. Due to the confusion in the market, users are not very clear about this, which is also the main reason why most manufacturers do not use it.
