Below, the cap be arranged on another shell end 122 and socket are described.
In on the shell end 122 being arranged at the side contrary with shell end 121, pipe installation portion 130 is also provided with cap 50 and socket 60, interior pipe 110 and UV-lamp 10 is arranged on predetermined position, and seals in liquid-tight manner.On the right side of the paper of Fig. 2, that is, the end face of contrary with part A side, does not receive external light source 70 in socket 60.Other aspects are with aforesaid to be arranged on situation about being arranged on the interior pipe installation portion 130 of shell end 121 identical, so detailed here.
In addition, as shown in Figure 7, the socket 80 without external light source open holes 68 can also be adopted.That is, by rubber or flexible resin etc., there is elastic material to be formed, and be made up of the pedestal 85 that the UV-lamp maintaining part 81 and diameter that are formed as the shape corresponding with interior pipe 110 are outward larger than this UV-lamp maintaining part 81.In addition, in the same manner as the socket 60 shown in Fig. 6, be formed with slit 89 in UV-lamp maintaining part 81, UV-lamp maintaining part 81 is in the C annular cylinder shape shape of the cross section C-shaped of giving prominence to from pedestal 85.Inner tube face 112 is opposed with the pedestal 85 of socket 80.
When such socket 60 not arranging external light source or socket 80 are disposed in another 122 side, shell end, the aforesaid part importing to the light that the external light source 70 in interior pipe 110 radiates from inner tube face 111, while internal surface reflection is carried out repeatedly in the inside of interior pipe 110, advance in the inner tube face 112 of side towards the opposite.Pedestal 85(65 is configured due to opposed with inner tube face 112), so by pedestal 85(65) reflection.By pedestal 85(65) part of light that reflects is by slit 89(69) irradiate discharge electrode 15.That is, the light radiated from external light source 70 these both sides of discharge electrode 14,15 at two ends to the separation being positioned at UV-lamp 10 irradiated.
When socket 60 of external light source are not received in setting, only prepare identical socket, thus can parts count be reduced, compared with the situation of prepared socket 80, can reduce costs.In addition, the slit 69(89 of shell end 121 and shell end 122 is laid respectively at) be preferably positioned at opposite position on straight line.During advancing while interreflection in interior pipe, a part of light transmission and advancing towards discharge tube.Therefore, by making the slit 69(89 at the two ends being positioned at UV-lamp 10) position opposed, thus can reduce in interior pipe advance during decrement, can irradiate via the electrode of slit to UV-lamp with less light of decaying.
External light source 70 is configured to: light never illustrated power supply applies high-tension to UV-lamp 10 while or before applying high-voltage, and extinguish after irradiating the light of the scheduled time.Because UV-lamp 10 is arranged in the shell 120 as space, darkroom.So the starting characteristic of the electric discharge of dark place is poor, but by from the irradiation of the light of external light source 70, starting characteristic in darkroom and discharge ionization voltage can be reduced and shorten the electric discharge time opening.In the present embodiment, due to outer electrode is configured in socket 60, so, can raise the efficiency and realize miniaturization.
When the light radiated from external light source 70 irradiates discharge electrode 14,15, initiating electron can be produced by photovoltaic effect.Especially, when carrying out rayed to the discharge electrode being coated with Cesium compound etc. and having the getter material of electron emission, the generation of initiating electron can be increased.When producing initiating electron, shorten the time opening of the electric discharge produced by the high-voltage being applied to discharge electrode 14,15.In the present embodiment, when external light source 70 is not lighted, need the lighting start time of several seconds to tens seconds, and when making external light source 70 light rear starting, can light within 0.1 second.That is, at the initial stage of the switch of closed liquid purifying processing device 100, the time of not carrying out UV treatment during the non-lighting time of UV-lamp 10 significantly reduces, and can eliminate the delay of UV treatment.
The illustration of above-mentioned embodiment only each side.The present invention does not explain to being defined property because these are recorded.Such as, the slit being arranged at socket is not limited to the grooving of rectangular shape, and can also adopt the grooving in the hole having circle, ellipse, trilateral, rectangle etc., socket can also be formed by the soft silicone material of light transmission.
In addition, in the above-described embodiment, and shell and/or interior pipe adopt dual structure and arrange the liquid purification and treatment device that multiple UV-lamp is also contained in double-sleeve structure of the present invention.And processed water is not limited to water, the liquid beyond water, the gas beyond air are processed and is also contained in the present invention.
