Abstract
The invention provides a short wavelength ultraviolet discharge lamp and an ultraviolet ray irradiator. In the ultraviolet discharge lamp comprising an insulated conductor coated with a fluororesin and radiating ultraviolet-rays having a wavelength of 220 nm or less, the generation of hydrogen fluoride and hydrofluoric acid harmful to the human body and causing reduction in quantity of radiation light is suppressed. The discharge lamp comprises a quartz glass tube (31), a pair of electrodes (32a, 32b) arranged at the opposite ends thereof, and a lead wire (60) extending along the outer wall of the quartz glass tube. The lead wire is obtained by covering an insulated conductor coated with an insulator composed of a fluororesin with a metal outer layer material. Since the fluororesin is not irradiated with ultraviolet rays while the lead wire is irradiated with ultraviolet-rays, hydrogen fluoride and hydrofluoric acid are not generated.

Background technology
The ultraviolet ray of short wavelength range is used for nuisance, organic decomposition and sterilization etc.Especially, the ultraviolet ray of the following wave-length coverage of 220nm has the energy of decomposing H-OH, thereby is applied in being used for the organic ultraviolet irradiation treatment device that decomposition water comprises.
Fig. 7 shows the example of ultraviolet irradiation treatment device in the past.Fig. 7 is the cutaway view that schematically shows the structure of ultraviolet irradiation treatment device in the past.
In Fig. 7, symbol 1 expression stainless steel cylinders (cylinder), its two ends are sealed by ring flange 7a, 7b.Processed water 5 is from the ring flange 7d side flow of the ring flange 7c side direction delivery port of water inlet, but, in cylindrical shell 1, on its axis, dispose a plurality of discoid back flow plate 6a, 6b, 6c, 6d, the 6e of perforate for the short circuit (short pass) that prevents processed water 5 with separating predetermined space.
In addition, light-transmission tube 2 and discharge lamp 4 are (many of light-transmission tube 2 and the discharge lamp 4 common configured in parallel, but only show 1 in Fig. 7) that are made of the quartz glass that has permeability from the following wave-length coverage of 220nm to long wavelength's scope equally.
See through light-transmission tube 2 and irradiation processed water 5 from the ultraviolet ray of discharge lamp 4 irradiations.
Hydrone H
2The bond energy of the H-OH of O is 499kJ/mol, and therefore, the ultraviolet ray of the following wavelength of 220nm can decomposition water molecule H
2O and generate the OH free radical.It is such that the OH free radical that is generated for example just is being shown below, and organic substance in the water is resolved into CO, CO
2, H
2O.
H
2O+hv (185nm) → H+OH free radical
C

mO
k+ OH free radical → CO, CO
2, H
2O
(n, m, k are positive integer)
Then, be described in detail with regard to the discharge lamp 4 among Fig. 7.
In body 31, enclose and mercury is arranged as luminescent metal.And the electrode 32b of a side is directed into along the outer wall of discharge lamp 4 by lead 3 that another is distolateral, is accommodated in the lamp holder 37 with the lead 3 that is connected in opposite side electrode 32a, and the terminal that is made of predetermined conductor can be situated between and is electrically connected with power supply by lamp socket 38.
And in cylindrical shell 1, feeding predetermined processed water on one side, on one side predetermined power supply is supplied on the discharge lamp 4 and when it is lighted, then radiate comprise 185nm ultraviolet ray at distinctive ultraviolet ray of interior mercury and visible light, thereby above-mentioned organic decomposition reaction takes place, so that the organic substance in the processed water becomes CO, CO
2, H
2O etc. and being removed.
But, discharge lamp 4 is along with the reduction of ultraviolet power output, need probably in the period of half a year~1, to regularly replace, but use in the discharge lamp 4 of fluororesin as the insulation cladding, have penetrating odor during replacing and the stimulation pain of skin at lead 3 in the past.This is the distinctive problem of device of utilizing the following wave-length coverage of 220nm, be utilize the ultraviolet irradiation treatment device of the wave-length coverage of 240~280nm meet less than phenomenon.
Promptly, the C-F bond energy of fluororesin is 539kJ/mol, therefore, does not also become obstacle even be subjected to the ultraviolet irradiation of the wave-length coverage of 240~280nm, but be exposed on the ultraviolet following time of the following wave-length coverage of 220nm, then the fluorine composition decomposes from the fluororesin that constitutes lead 3.Can think that this fluorine and moisture on every side react, thereby generate harmful hydrogen fluoride or hydrofluoric acid.
When generating this hydrogen fluoride or hydrofluoric acid, there are the following problems: with the quartz glass reaction of the constituent material of light-transmission tube 2 and produce gonorrhoea (turning white) on light-transmission tube 2, under the effect of this gonorrhoea, to the irradiation light quantity reduction of object being treated, thereby treatment effeciency descends.In addition, hydrogen fluoride or hydrofluoric acid are harmful, therefore also exist to make operational environment worsen such problem.
Therefore, proposed the ultraviolet irradiation treatment device of following structure: as the lead of discharge lamp, the nonisulated lead that uses not insulation to coat is not as long as be cut off the supply power of discharge lamp power supply, then can not extract discharge lamp (for example, with reference to patent documentation 1) from light-transmission tube.
But, in the ultraviolet irradiation treatment device of patent documentation 1 described structure, and though can make this device novelly, the problem that exists is: and under the situation with the device of in the past constructing that has been provided with, repacking needs expense and time.In addition, also exist the operator to be difficult to manipulate nonisulated lead as the such problem of the discharge lamp of lead.
For fear of generating hydrogen fluoride or hydrofluoric acid, also can consider for example to use the macromolecular compound such as polyimides, polyamide-imides of non-halogen system and the inorganic insulator as mica insulator (for example, with reference to patent documentation 2) as the formation lead.
But, the insulator that so non-halogen is is compared with fluororesin, and dielectric constant is higher, and therefore the problem that exists is to increase leakage current easily.
That is, the dielectric constant of fluororesin is about 2.1, and for example the dielectric constant of polyimides and polyamide-imides is more than 3.2, and mica is more than 7.0, and the dielectric constant of the insulator of most halogen system has the tendency higher than fluororesin.
Dielectric capacitance is directly proportional with dielectric constant, if thereby dielectric constant higher, then over the ground between and the capacitance between contrary current potential just increase.
Therefore, from the relation of I=V * ω C (I is that electric current, V are that voltage, C are capacitances, and ω is a constant, ω=2 π f) as can be known, the leakage current that flows to ground or contrary current potential via electric capacity increases easily.
Usually, on ultraviolet irradiation treatment device, be equipped with the electric ballast that a plurality of discharge lamps, a plurality of high frequencies that are used to drive 20~100kHz are stably lighted these discharge lamps.Electric ballast has added following various functions: straighforward operations such as lighting, turn off the light, full luminous point is bright, light modulation is lighted, when discharge lamp does not work light that the temperature anomaly when overheated in abnormal show, the power operation dish shows so that for the protective circuit of the expansion that prevents accident in advance etc.
These functions Weak current signal manipulation of number mA level, even the increase of leakage current is very small, also might cause the misoperation of electric ballast, therefore, using high dielectric constant materials such as polyimides, polyamide-imides or mica may not be the best way as the insulator of lead.
