Description
[technical field]
The present invention relates to uviol lamp, particularly relate to a kind of microwave electrodeless ultraviolet light device.
[background technology]
Uviol lamp product has had a lot of year history for sterilization, because the DNA structure of various viruses, antibacterial and other pathogen in the broken ring water body of the energy of the ultraviolet photon of the 254nm wavelength that uviol lamp sends or air, mainly make the various structural bonds fracture in DNA or photochemical polymerization reaction occurs, such as make thymine dimer in DNA, so that various viruses, antibacterial and other pathogen are lost replicates fertility, reach the effect of sterilizing.Conventional uviol lamp is all have extreme ultraviolet lamp, it is simply that the uviol lamp similar with common fluorescent tube, with electrode discharge excitation amalgam or liquid hydrargyrum, produces multiwave ultraviolet light.Electrode is generally adopted tinsel or sheet is made, because metal electrode material is different from quartz glass lamp vessel material thermal expansion coefficient, in use can produce gap gradually, causes filling gas leakage in fluorescent tube, and then fluorescent tube lost efficacy.The life-span of this fluorescent tube, maximum 10000 hours, the actually active use time only had 5000-6000 hour, so use cost is higher generally all without oversize.
Therefore there are many research institutions and company, the uviol lamp of electrodeless mode is being studied by scientific research institutions, electrodeless ultraviolet lamp including the coiling mode similar with conventional Non-polar illuminating lamp, LED uviol lamp, and microwave excited electrodeless ultraviolet lamp, comparatively speaking, the high-power electrodeless lamp of disinfection, the cost that only microwave excitation mode is done at present is minimum, it is also easy to be made to complete equipment use, such as the utility model patent (ultra-high power electrodeless ultraviolet lamp) that application number is 201120189124.0, the life-span of micro-wave nonpolar lamp is extremely long, more than 50000 hours, luminous efficiency relatively has pole lamp high by more than 20%, and fluorescent tube is with low cost, change simple and convenient, it it is a kind of disinfection light source having extremely strong competitiveness.
There is extreme ultraviolet lamp to have a lot of advantage although microwave electrodeless lamp is relatively common, but there are some problems.First, microwave electrodeless lamp is to generate the luminescence of microwave excitation Non-polarized lamp by magnetron, and the reasonable microwave magnetron power that present cost controls is typically all about 1000 watts, and power is relatively strong；Secondly, microwave current energy is all single output, it is impossible to is uniformly divided into several equal portions and acts on simultaneously；3rd, the quartz burner of disinfection is all low pressure mercury lamp, power can not be too big, and temperature can not be too high because temperature high after can there is spectral shift phenomenon, affect disinfecting/sterilizing efficiency；4th, to fill quartz glass sleeve outside when microwave electrodeless lamp processes for water, the cost of sleeve pipe constrains the external diameter of Non-polarized lamp.
Because these reasons, present microwave electrodeless lamp is all that a power supply drives a microwave source, microwave waveguide is all that a port enters, another port goes out, resonator cavity is all adopt long straight drum structure, it is typically all more than 1200mm length, built-in 4 electrodeless lamp tubes of resonator cavity, fluorescent tube length 1200mm, 4 tubes are about 200 watts every on average, when microwave is come in from waveguide time, fluorescent tube near waveguides sections can be first bright, after fluorescent tube bottom the resonator cavity bright, by the time time all lamp is lighted, the brightness of lamp tube ends is different, the temperature of whole fluorescent tube is also higher, even can more than 100 DEG C, final result is exactly that efficiency of energy utilization is on the low side, specific investment cost cost is high.
[summary of the invention]
