Description
[technical field]
The present invention relates to ultraviolet lamp more particularly to a kind of microwave electrodeless ultraviolet light devices.
[background technique]
Ultraviolet lamp product has had many year history for sterilization, because the 254nm wavelength that ultraviolet lamp issues
The energy of ultraviolet photon breaks the DNA structure of various viruses, bacterium and other pathogens in ring water body or air, mainly makes
The fracture of various structural bonds or generation photochemical polymerization reaction in DNA, such as make thymine dimer in DNA, to make each
Kind virus, bacterium and other pathogens lose duplication fertility, achieve the effect that sterilizing.Common ultraviolet lamp is all to have pole
Ultraviolet lamp is exactly the ultraviolet lamp similar with common fluorescent tube, with electrode discharge excitation amalgam or liquid mercury, generates multiwave purple
Outer light.Electrode generally uses wire or piece to be made, because of metal electrode material and quartz glass lamp vessel material thermal expansion coefficient
Difference can gradually generate gap in use, cause filling gas in fluorescent tube to leak, then fluorescent tube fails.This fluorescent tube
Service life generally all will not be too long, it is most 10000 hours or so, actually active there was only 5000-6000 hours using the time, so
Higher operating costs.
Therefore have many research institutions and company, scientific research institutions in the ultraviolet lamp for studying electrodeless mode, including with conventional nothing
Electrodeless ultraviolet lamp, LED ultraviolet lamp and the microwave excited electrodeless ultraviolet lamp of the similar coiling mode of pole headlamp, compare and
Speech, the high-power electrodeless lamp of disinfection and sterilization, the cost for only having microwave excitation mode to do at present is minimum, is also easy to be made to be arranged
Standby to use, such as application No. is 201120189124.0 utility model patent (ultra-high power electrodeless ultraviolet lamp), micro-wave nonpolars
The service life of lamp is extremely long, and more than 50000 hours, luminous efficiency was high by 20% or more compared with there is pole lamp, and fluorescent tube is low in cost, and replacement is simple
It is convenient, it is a kind of disinfection and sterilization light source for having extremely strong competitiveness.
Although microwave electrodeless lamp commonly has extreme ultraviolet lamp there are many advantages relatively, still there are some problems.
Firstly, microwave electrodeless lamp is to generate microwave excitation Non-polarized lamp by magnetron to shine, present cost control it is relatively good micro-
Wave magnetic control tube power is typically all 1000 watts or so, and power is relatively strong；Secondly, microwave current energy is all single output, no
Several equal portions can be uniformly divided into while being acted on；Third, the quartz burner of disinfection and sterilization are all low pressure mercury lamps, and power cannot be too
Greatly, temperature cannot be too high, because spectral shift phenomenon can occur after temperature is high, influences disinfecting/sterilizing efficiency；4th, microwave without
Outside will fill quartz glass sleeve when extreme ultraviolet lamp is used for water process, and the cost of casing constrains the outer diameter of Non-polarized lamp.
Because of these reasons, present microwave electrodeless lamp is all that a power supply drives a microwave source, microwave waveguide
All be a port into, another port goes out, resonant cavity be all using long straight drum structure, typically 1200mm or more length,
Built-in 4 electrodeless lamp tubes of resonant cavity, fluorescent tube length 1200mm, average about 200 watts every of 4 tubes, when microwave is from waveguide transmission
When coming in, the fluorescent tube close to waveguide portion can be first bright, bright after the fluorescent tube of resonant cavity bottom, lights until whole lamps
When, the brightness of lamp tube ends is different, and the temperature of entire fluorescent tube is also higher, or even can be more than 100 DEG C, and final result is exactly
Efficiency of energy utilization is relatively low, and specific investment cost is at high cost.
