Description
Technical field
The invention belongs to the ultraviolet technique field, be specifically related to a kind of straight screw electrode quartz burner and application thereof.
Background technology
(200 ~ 280nn) radio sterilizations (destroy the outer pellicle of bacterium because quartz burner can produce efficient UV-C shortwave segment length ultraviolet simultaneously, make its dehydration death) and VUV vacuum ultraviolet (VUV) (200nm is following) effusion, combine with airborne oxygen, produce ozone, ozone can decompose materials such as harmful stupid, phenol, formaldehyde in the air.Therefore, the used ultraviolet radiation for sterilizing and disinfecting fluorescent tube kind of people's sphere of life is a lot, mainly is respectively straight tube and compact from cast, distinguishes from cathode emission mechanism and mainly contains hot cathode and cold cathode.Because hot cathode emission effciency height, can obtain higher ultra-violet radiation efficient under the prerequisite of pipe range, caliber and the identical input power of whole lamp relatively, so no matter the hot cathode quartz burner is to air, space sterilizing, still the sterilizing of water has all been occupied the deal of absolute vast scale.
In addition, also having a kind of is the cold cathode uv lamp pipe, and general the making becomes the small-sized ultraviolet sterilization device of being convenient to keeping, carrying.Because science and technology is a double-edged sword, be that continuous progress in science and technology is brought great material enjoyment and cheap to the mankind on the one hand, destroyed the ecological balance on the one hand again, causing bacteria breed and harmful inorganic substances spreads unchecked, as " besieged city " to people's living environment such as stupid, phenol, aldehyde, have to make that people produce Psychological Panic, to household and a kind of suitable (being easy to carry) UV-device of going out to wish to have as small-sized, at any time to own long-term or interim living environment sterilizing of living, improve life quality, satisfy physiology and psychological needs.
But, the making of hot cathode quartz burner has followed the design concept and the manufacture craft of hot-cathode fluorescent lamp always since coming out, negative electrode as most critical also is filament of employing and the horizontal dress of fluorescent tube caliber level (being called " flat silk " in the industry), filament energising decomposition on the exhaust car behind the coating triplex carbonate electronics powder; Decomposition temperature is controlled at 600 ~ 950 ℃, decomposes atmosphere is 10
-1~ 10
-2Torr (1 torr=133.3 handkerchiefs).
Hold because easy temperature control system but atmosphere are difficult.These are 10 years old
-1 ~-2The pressure of torr is that (system is a negative pressure to the suction pressure that is far longer than system, and the vacuum degree of bleeding is 10
-3 ~-6Handkerchief), and this pressure to form be that the pressure of the carbon dioxide gas that discharges when being decomposed by triplex carbonate electronics powder energising constitutes and (is subjected to the control electronics deal of traditional filament energising manufacture craft at present fully, the electronics deal that applies on the filament is extremely limited, the carbon dioxide that discharges during decomposition is also limited, be difficult to satisfy this 10
-1 ~-2The pressure of torr, therefore, the cathode electronics bisque structure after the decomposition is looser, not anti-positive ion bombardment when fluorescent tube starts is easy to sputter, also is easy to during work evapotranspire).So the hot cathode quartz burner rated life time standard that present prior art is made just fixes at 1000h, the real standard burning-point uses tens, hundred hour negative electrodes just to begin sputter, has a strong impact on the ultra-violet radiation efficient and the useful life of fluorescent tube.
In addition, it is thick that ultraviolet HCFL follows the design of fluorescent lamp caliber, causes the negative electrode decomposition space big, is one of reason that the negative electrode decomposition pressure is too low, decomposition atmosphere is bad.Though being design fluorescent tube caliber, more fatal defective do not consider that the two all is a low-pressure gaseous discharge lamp, in the gross differences of the mechanism such as generation condition, whereabouts and purposes of ultraviolet photon.Fluorescent lamp is to adopt common soft material glass-tube, and thermal conduction characteristic own is just bad, applies phosphor powder layer and equals to have added a heat-insulation layer afterwards, causes the fluorescent lamp temperature rise to improve.And in view of fluorescent material easily by ultraviolet photon, especially 185nm vacuum ultraviolet deterioration, the effective way that the control lamp hole temperature obtains best mercury-vapor pressure is to strengthen caliber to dispel the heat, also increase simultaneously the distance of phosphor powder layer and fluorescent tube axle center region of discharge, reduce the radiation of ultraviolet photon, delay the light decay of fluorescent tube fluorescent material.
Quartz burner is with regard to complete different fluorescent lamps, and the conductive coefficient of quartz glass tube do not say there be not the heat insulation of phosphor powder layer far above general material glass, and is general all on the low side in the lamp hole temperature that obtains best mercury-vapor pressure during the work of quartz burner.At this moment need one of factor that reduces caliber.Its two, tubule footpath helps ultraviolet photon greatly and (reduces the probability of its elastic collision and inelastic collision in fluorescent tube) and distance from path that tube wall is overflowed, improves radiation intensity and illumination.Its three, save the glass-tube material, the quartz glass tube that is used for quartz burner requires hydroxy radical content＜5ppm, the manufacturing process highly energy-consuming, costs an arm and a leg.
So hot cathode quartz burner design caliber is to be unfavorable for the control of fluorescent tube manufacture craft according to conventional fluorescent lamps, also has a strong impact on lamp works efficient and radiation intensity, illumination and life-span, has also wasted a large amount of valuable quartzy tubing.
The selection of cold cathode uv lamp pipe electrode also is consistent with CCFL, is to make of wrought iron nickel plating or oxygen-free copper to become tubular, and be a kind of typical glow discharge.Though the glass-tube design is thin, glow discharge inefficiency (1/3 ~ 1/2 efficient that is about the HCFL of same design), but cold cathode lamp tube lifetime specific heat negative electrode is long, especially is fit to make the fluorescent tube of superfine pipe diameter ultra-small volume; And not having a kind of product can make its update, prior art is still in continuous application.
These above-mentioned defectives have all hindered the manufacture craft of ultraviolet hot cathode and cold cathode fluorescent lamp fluorescent tube, also have a strong impact on lamp works efficient and radiation intensity, illumination and life-span, the obstruction small-power (as＜10W) quartz burner enters the progress of household consumption.
Enter this century, because the maturation of low-pressure gaseous discharge lamp electric ballast is with fast-developing, people drive the epoch that fluorescent tube steps into the electronics high-frequency lighting by the inductance low frequency, low pressure gaseous discharge fluorescent lamp manufacturing technology obtains fast development, as " Filament-free heated cathode fluorescent lamp " (Chinese invention patent ZL2004 1 0017780.7) and " a kind of non-filament florescent lamp in the work of brightness arc transition region " (China Patent No.: ZL2006 1 0147206.2) and " the concentrated decomposition and the active device of gaseous discharge lamp oxide coated cathode " (Chinese utility model patent number 2,004 2 0022345.9).
