Abstract
The utility model relates to a quasi-molecule discharge tube, comprising an inner tube and an outer tube both fixed along the same axis while the terminals of the tubes are closed to form an aerating space. The inboard inner tube is filled with reflecting metal fine stuff wherein the stuff and the inner tube are formed together to be the inner electrode and metal wire enwinds to the outside of the outer tube provides the outer electrode. When high frequency and high-voltage alternating current are added to the two electrodes, quasi-molecule discharge tube can radiate single-waved ultraviolet. The utility model has the advantages that the tube is easy to make, low in cost and has a long durability.
Description
Technical field
The utility model relates to a kind of discharge tube that is used as the ultraviolet light source that photochemical reaction uses, and particularly a kind of outer tube and interior pipe is configured in the coaxial quasi-molecule discharge tube of going up, having double-sleeve structure.
Background field
The quasi-molecule discharge tube has the speciality of the vacuum-ultraviolet light that radiates single wavelength that can be strong, for example uses in the quasi-molecule discharge tube of xenon as discharge gas, and the vacuum ultraviolet (VUV) that radiates wavelength 172nm is only known.In addition, under the situation of the mist of krypton and chlorine, radiate the ultraviolet light of wavelength 222nm.By changing the discharge gas in the container, can radiate the light of various wavelength.Existing quasi-molecule discharge tube is complex structure often, and manufacture craft is complicated, the cost of manufacture height.
The utility model content
It is simple that the utility model aims to provide a kind of making, with low cost, the quasi-molecule discharge tube of luminescence-utraviolet efficient height and long service life.
For solving the problems of the technologies described above, the basic design of the technical scheme that the utility model adopted is: a kind of quasi-molecule discharge tube, outer tube and interior pipe are nested, form the structure of dual pipe, outer tube and interior pipe two ends are sealed mutually, form the airtight plenum space within the outer tube outside the interior pipe, and interior pipe inboard is filled with the reflecting metal fines, the metal fines connects lead-out wire, and both constitute interior electrode together; The UV resistant wire of outer tube outer felt coiling round is as external electrode.
The utility model is all right: outer tube and interior pipe are quartz glass tube, at the inboard reflecting metal fines of filling of interior pipe is the material of soft aluminium matter, insert the cooling metallic water pipe in the middle of the interior electrode, back inert gas injecting, halogen gas, halogenation inert gas or mercury halide gas are evacuated in the plenum space, the outer tube outer felt around the UV resistant wire can be nickel wire or stainless steel wire, its diameter is generally 0.3～1mm, and the spacing distance between the coiling is generally 0.5～9mm.
The utility model is owing to be filled with the reflecting metal fines in interior pipe inboard, so reflecting effect is good, and do not need special interior electrode plating film device, manufacturing process is simple, cost reduces greatly, and pipe range can not limit, and caliber can be coarse to fine, many discharge tubes can form a relative uniform surface light source side by side the time.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail: a kind of quasi-molecule discharge tube, with the outer tube 1 of quartz glass and interior pipe 2 be nested be configured in coaxial on, outer tube 1 and interior pipe 2 two ends are sealed mutually, form the airtight plenum space 7 of the hollow cylinder shape in an outer tube 1 inboard and interior pipe 2 outsides.Inert gas injecting, halogen gas, halogenation inert gas or mercury halide gas are filled with soft aluminium matter reflecting metal fines 5 after being evacuated in the plenum space 7 in interior pipe 2 inboards, and metal fines 5 connects lead-out wires and electrode 6 in lead-out wire constitutes; Can also insert cooling metallic water pipe (not shown) in the middle of the interior electrode 6, outer tube 1 outer felt is wound with the UV resistant wire 3 of coiled type as external electrode 4, UV resistant wire 3 can be nickel wire or stainless steel wire, its diameter is generally 0.3～1mm, and the spacing distance between the coiling is generally 0.5～9mm.
After two interpolars were increased the frequency High Level AC Voltage, the quasi-molecule discharge tube can send the comparatively single ultraviolet ray of wavelength between the wire that twines.
