Abstract
The utility model relates to a cold cathode high strength quartz ultraviolet sterilizing lamp. Primarily, a quartz glass-tube whose pipe diameter ranges from 15 mm to 18 mm gets sealing connection to the cylindrical or helical cold cathode. And the utility model is formed by evacuating of high vacuum. The lifetime of this cold cathode high strength quartz ultraviolet lamp can reach more than 15 000 hours, and luminous intensity can reach 220 microwatt / square centimetre to 260 microwatt / square centimetre. This ultraviolet lamp primarily sterilizes nature drink-water or air in large size space.
Description
Technical field
The utility model relates to electronic vacuum and health medical domain.
Background technology
Quartz burner commonly used is made by common quartz glass or high boron glass, and its structure is a hot cathode filament formula fluorescent tube.Though this fluorescent tube also can send the ultraviolet spectrogram of 254 nanometers, UV intensity is low, and useful life is not long, is difficult to adapt to the air of large space or disinfecting big flow running water.
Summary of the invention
The purpose of this utility model just provides the quartz burner of a kind of simple in structure, long-life, high emission ability, can overcome traditional hot negative electrode quartz burner effectively, and efficient is low, and the life-span is short, safeguards the weakness of changing trouble.
In order to achieve the above object, the technical solution of the utility model is the structure that has changed general quartz burner, has adopted multinomial new technology.The one, the hot cathode filament has been made into the cold cathode that unipods is exported, make tubular or helix heater.In the lamp works process, negative electrode is in same current potential, and that is to say in the starting and the course of work does not have heater current all the time, can prolong the cathode life 2-3 time doubly like this.It is exactly that cathode emissive area has increased that cold cathode also has a big advantage, and electron emissivity is improved greatly.The secondth, the diameter of quartz ampoule from original 20 millimeters to 26 millimeters, is reduced to 15 millimeters to 18 millimeters.According to the electronic vacuum theory analysis, under the identical situation of input power, diameter is more little, and just the inner surface of tube is long-pending more little, and the power level that unit are is excited is big more, and ultraviolet emission intensity is also big more.The 3rd is on the cold cathode surface, with the method for electrophoresis, coated the efficent electronic powder.In order to improve the electron emissivity of filament.Promptly increase the cathode electronics work function of fluorescent tube.The 4th is the new technology that adopts high vacuum exhaustion and baking oven to degas.Traditional method for exhausting is to heat with duration and degree of heating to reach the method that fluorescent tube degass, and uses the baking oven degasification instead, and it is rapider more thorough that fluorescent tube is degassed.Thereby vacuum degree greatly improves.Through the national inspection centers test, the ultraviolet emission intensity of cold cathode quartz burner can reach 200 to 240 microwatt/square centimeters, and the UV intensity of general hot cathode quartz burner has only 120 to 160 microwatt/square centimeters.
Description of drawings
Accompanying drawing is circuit theory diagrams of the present utility model.
1 ozone free quartz glass tube, 2 cold cathodes, 3 cold cathode unipods lead-out wires, 4 high-frequency electronic ballasts among the figure.
Embodiment
Cold cathode high-intensity ultraviolet fluorescent tube, under the effect of high-frequency electronic ballast, conducting fast, activating a large amount of wavelength that come out is the ultraviolet ray of 254 nanometers, sees through quartz glass tube to the water and air sterilizing.
Quartz burner is through clean, and behind the good cold cathode of sealing-in, places the high vacuum system exhaust.And progressively heat with baking oven.In exhaust process, look the vacuum degree situation, repeatedly aging to the cold cathode energising, till reaching cold cathode brightness sudden strain of a muscle in vain.In fluorescent tube, add a small amount of high-purity mercury and high-purity argon gas, in order to reach the purpose of conducting fluorescent tube and protection negative electrode.The fluorescent tube that makes, under the effect in high-frequency electronic ballast, connect fluorescent tube by ozone free quartz glass tube 1, the fluorescent tube UltraDialUp is conducted, cold cathode 2 emitting electrons activate mercury vapour and produce intensive ultraviolet, ultraviolet ray see through quartz glass tube 1 and outwards the width of cloth penetrate 254 nanometer ultraviolet rays, water or air are implemented sterilizing.
