Description

Ultraviolet liquid processing device {ULTRAVIOLET RAY LIQUID PROCESSING DEVICE}

The ultraviolet liquid processing apparatus or system which performs liquid processing, such as sterilization and disinfection of bacteria in a to-be-processed liquid by ultraviolet irradiation, is a semiconductor industrial pure water production line, a pharmaceutical industrial sterile water production line, a food industrial water sterilization line, a fishery It is applied in various fields such as aquaculture water sterilization line, drainage and sewage treatment line. The ultraviolet lamp used for the treatment is infiltrated in the liquid to be treated in a state in which it is liquid-tightly housed in a transparent hard lamp protection tube made of quartz glass. In this case, a channel installation type for installing an ultraviolet lamp in a channel through which the liquid to be treated flows, and a waste channel for installing an ultraviolet lamp in a sealed channel such as a pipe through which the liquid to be treated flows or a sealed tube. There is an installation type (in a sealed pipe). The ultraviolet lamp is turned on by generating a predetermined high frequency signal from a commercial AC source through a lighting ballast and supplying the high frequency signal to the ultraviolet lamp.

In the conventional ultraviolet liquid processing apparatus, the lamp lighting ballast is separated from the ultraviolet lamp and disposed in a power box, and a high frequency signal output from each ballast provided for each ultraviolet lamp is supplied to each ultraviolet lamp through separate wiring. It is supposed to be. In this case, in the type of installing the ultraviolet lamp in the sealed tube, maintenance is performed at both ends of the sealed tube through the liquid to be treated to be tightly shut off from the space in the sealed tube and through the space in the lamp protective tube. A cover is provided, and wiring from the ballast in this maintenance cover is electrically connected to the ultraviolet lamp in the lamp protection tube through the socket. In addition, the lamp is replaced by attaching and detaching the socket at the location of the maintenance cover to allow the ultraviolet lamp to pass through the lamp protection tube.

Since the ballast for lamp lighting generates a large amount of heat when the lamp is energized, it is necessary to take measures for heat dissipation. Therefore, each fan is equipped with a heat dissipation fan or a heat sink, and the cooling fan is installed in the power box which accommodated these ballasts. Therefore, since the size of each ballast is large and the cooling fan is also large, the problem that the size of the entire power supply box is enlarged cannot be avoided. In addition, since the problem of contamination by dust is caused by blowing the inside of the power supply box by a fan, regular maintenance is necessary, and in view of the life of the fan, regular maintenance is also necessary. Moreover, since the wiring exposed to the outside from a power supply box to a lamp is a high frequency output wiring from a ballast, it also raises a problem of high frequency noise.

(Initiation of invention)

SUMMARY OF THE INVENTION The present invention has been made in view of the foregoing, and an object thereof is to provide an ultraviolet liquid processing apparatus and method capable of solving at least one of the various problems described above.

The ultraviolet liquid processing apparatus which concerns on this invention is equipped with the pipe line through a to-be-processed liquid, the transparent lamp protection tube arrange | positioned in the said pipe | line and contacting the said to-be-processed liquid, and the ultraviolet lamp accommodated in the said lamp protection tube, The said ultraviolet lamp An ultraviolet liquid processing apparatus for treating the liquid to be treated by ultraviolet rays irradiated from the light source, wherein the stabilizer for the ultraviolet lamp is disposed close to an outer surface of the pipeline so as to be capable of dissipating heat from the pipeline. According to this configuration, since the ballast of the ultraviolet lamp is disposed close to the outer surface of the pipeline through the liquid to be treated, the ballast does not directly contact the liquid to be processed in the pipeline, but indirectly contacts the liquid to be treated through the pipeline. As a result, the heat dissipation of the ballast can be promoted due to the cooling effect. Therefore, the heat dissipation means of the ballast can be made unnecessary, or the scale thereof can be reduced, and the size of the ballast can be miniaturized. In addition, by eliminating the heat dissipation means of the ballast or reducing its scale, the necessity of the prior art that the ballast must be stored in the power box for heat dissipation can be avoided, and the pipe is separated from the power box. By arranging the ballast on the side, the size of the power supply box can be made much smaller than the conventional one. Therefore, it is possible to provide an easy-to-use ultraviolet liquid processing apparatus which does not occupy an installation area of a power box and is easy to apply to a narrow installation place. In addition, in order to compensate for the cooling effect of the ballast, a cooling fan may be further provided at a suitable location outside the pipeline as necessary, but in this case, a small fan may be used.

One embodiment of the present invention is characterized in that a plurality of the ultraviolet lamps are provided, and at least one ballast for at least one lamp corresponding to the at least one ultraviolet lamp is disposed on an outer surface of the conduit. In this case, the single ballast is not in direct contact with the liquid to be processed in the conduit, but is indirectly in contact with the liquid to be treated in the pipe, so that a corresponding cooling effect can be obtained without a special heat dissipation fan or heat sink.

According to another embodiment of the present invention, a plurality of the ultraviolet lamps are provided, and at least one ballast for multilight corresponding to at least two ultraviolet lamps is arranged on an outer surface of the pipe. In this case, the multi-stable ballast is not in direct contact with the liquid to be processed in the conduit, but is indirectly in contact with the liquid to be treated in the pipe, so that a corresponding cooling effect can be obtained without a special heat dissipation fan or heat sink.

Still another embodiment of the present invention is characterized in that the ballast is arranged by sandwiching a heat-sensitive conductive adhesive with respect to an outer surface of the conduit. In this case, since the bottom of the ballast can be attached to the outer surface of the pipeline in close contact with a heat-sensitive adhesive, heat of the ballast can be radiated to the outer surface of the pipe through the heat-sensitive adhesive. Thereby, a cooling effect can fully be acquired by indirectly contacting the to-be-processed liquid in a closed pipe.

In still another embodiment of the present invention, the ballast is disposed by sandwiching a soft shock absorbing material having a double heat conductivity between the outer surface of the conduit. In this case, since the flat bottom of the ballast can be brought into close contact with the curved surface of the outer circumference of the pipe through a soft thermal shock absorbing material, the heat of the ballast can be radiated to the outer surface of the pipe through the heat absorbing buffer. Thereby, a cooling effect can fully be acquired by indirectly bonding to the to-be-processed liquid in a piping.

According to still another embodiment of the present invention, the ballast is disposed by sandwiching a heat dissipation medium between the outer surface of the conduit and the ballast. As an example, a heat dissipation medium container (for example, a coolant tank) is formed on an outer surface of the conduit, and a cooling medium (for example, coolant) is stored in the heat dissipation medium container, and the ballast is contacted with the heat dissipation medium container. Place it.

According to another aspect of the present invention, there is provided an ultraviolet liquid processing apparatus including a conduit through a liquid to be treated, a transparent lamp protective tube disposed in the conduit and in contact with the liquid to be treated, an ultraviolet lamp housed in the lamp protective tube, and a heat dissipation medium. And a heat dissipation unit including a stabilizer for the ultraviolet lamp disposed in contact with the heat dissipation unit, the heat dissipation being performed through the heat dissipation medium, and the heat dissipation unit close to an outer surface of the conduit so as to be able to dissipate the heat dissipation unit. It is characterized by the arrangement. Also in this case, the same effect as described above is achieved. That is, since the heat radiating part is arrange | positioned near the outer surface of the pipe | tube which passes through a to-be-processed liquid, the heat of the heat radiating medium which took the heat radiation of a stabilizer can be cooled efficiently by the heat of cooling of a to-be-processed liquid. Therefore, more efficient heat dissipation can be performed than heat dissipation means such as a conventional heat dissipation fan which dissipates in air.

In addition, the method according to the present invention includes a conduit through the liquid to be treated, a transmissive lamp protective tube disposed in the conduit and in contact with the liquid to be treated, and an ultraviolet lamp housed in the lamp protective tube and irradiated from the ultraviolet lamp. An ultraviolet liquid processing apparatus for treating the liquid to be treated by ultraviolet rays, the method of arranging a ballast for the ultraviolet lamp, the method comprising arranging the ballast in close proximity to an outer surface of the conduit such that heat can be radiated to the conduit. It is characterized by.

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described in detail with reference to an accompanying drawing.

BRIEF DESCRIPTION OF THE DRAWINGS Fig. 1 is a cross-sectional schematic diagram showing an embodiment of the present invention in an ultraviolet liquid processing apparatus of a type for performing ultraviolet treatment through a liquid to be processed P in a sealed pipe line 1. The pipe line (hereinafter referred to as a closed tube for convenience) 1 passing through the liquid to be treated P is hermetically sealed at both ends by the seal portions 2 and 3, and the blood drawn from the liquid inlet 1a. Process liquid P is made to pass through a pipe, and it discharges from liquid outlet 1b. In the closed tube 1, the ultraviolet lamp 5 is arrange | positioned in the state liquid-tightly inserted in the translucent hard lamp protection tube 4 made from quartz glass. The end covers 6 and 7 provided at both ends of the hermetic pipe 1 are hermetically blocked from the inner space of the hermetic pipe 1 through the seal parts 2 and 3, and are also inside the lamp protection tube 4. It is a state through space. That is, both ends of the lamp protection tube 4 exit the seal portions 2 and 3 and are directed to the spaces in the end covers 6 and 7, whereby the ultraviolet lamp 5 is replaced by the lamp protection tube 4 at its replacement. It is possible to enter and exit from the end of the). The cover 6 and 7 can be opened and closed arbitrarily by the well-known structure which is not shown in figure, and of course, it opens when the ultraviolet lamp 5 enters. The ballast 8 for lighting of the ultraviolet lamp 5 is arrange | positioned in the appropriate position closely to the outer periphery of the sealing tube 1. Usually, the hermetic pipe 1 is comprised from metal with good thermal conductivity, such as stainless steel.

The function of the stabilizer 8 itself is to exchange direct current AC signals, convert the DC signals into predetermined high frequency signals for lamp lighting, and output them in the same manner as known. The ballast 8 in the example of FIG. 1 does not directly contact the liquid to be processed in the hermetic pipe 1, but is indirectly contacted with the liquid to be treated through the hermetic pipe 1 by being in close contact with the outer circumference of the hermetic pipe 1. Contact Thereby, since the sealing tube 1 is cooled by the to-be-processed liquid, corresponding cooling effect can be acquired without a special heat radiating fan or a heat sink. Known lighting ballasts need to provide a heat dissipation fan or a heat sink, but in this embodiment, there is no need to provide a heat dissipation fan or heat sink in the ballast 8, and the size of the ballast can be reduced. ) Is easy to install. In addition, in order to supplement the cooling effect, you may provide the cooling fan 9 in the suitable location of the exterior (outer surface) of the closed tube 1. In this case, since the supplementary cooling effect may be obtained, the fan 9 may be a small fan.

Although the wiring for receiving a commercial AC signal from the outside is connected to the ballast 8, since the external wiring for this is for a commercial AC signal, there is no problem such as high frequency noise. The high frequency signal for lighting generated from the ballast 8 is supplied to the corresponding ultraviolet lamp 5 in the lamp protection tube 4 through suitable wiring, socket connector and the like. In this case, since the distance between the ballast 8 and the ultraviolet lamp 5 is close, there is little problem of high frequency noise.

In FIG. 1, only one ultraviolet lamp 5 is shown, but as shown in FIG. 2 in the hermetic tube 1, a plurality of ultraviolet lamps 5 (UV lamp in the example shown in the drawing) as necessary. 3 are arranged in a state where three are inserted into the respective lamp protection tubes 4. In that case, a plurality of ballasts 8 are arranged outside the sealed tube 1 in correspondence with the respective ultraviolet lamps 5. Each ballast 8 is a single ballast, and the high-frequency signal for lighting generated from each ballast 8 corresponds to the corresponding ultraviolet lamp 5 in each lamp protection tube 4 through appropriate wiring, sockets, connectors, and the like. Supplied to. Although each ballast 8 shown in FIG. 2 does not directly contact the to-be-processed liquid P in the hermetically sealed tube 1, it adheres to the outer periphery of the hermetically sealed tube 1, and the to-be-processed liquid through this hermetically sealed tube 1 is carried out. Thermal conductivity is good and indirectly in close contact. Thereby, since the sealing tube 1 is cooled by the to-be-processed liquid, corresponding cooling effect can be acquired without a special heat radiating fan or a heat sink. Of course, in order to compensate for the cooling effect, a cooling fan (not shown) may be provided at a suitable location outside of the sealed tube 1. In that case, the fan may be a small fan, as long as it can be provided with a complementary cooling effect.

Although the ballast 8 for a single lamp was shown in FIG. 2, as a use form of the ballast 8, 2 or more ultraviolet lamps 5 may be used as a ballast for multilights which light. As an example, the ballast 8 is used as a ballast for multiple lamps of the three ultraviolet lamps 5, as shown in FIG. Even in that case, the ballast 8 is arranged in close contact with the outer circumference of the sealed tube 1. In this case, the high frequency signal for lighting generated from the ballast 8 is supplied to the corresponding ultraviolet lamp 5 in each lamp protection tube 4 through suitable wiring, socket connector and the like. The stabilizer 8 shown in FIG. 3 does not directly contact the liquid to be processed in the sealed tube 1, but is indirectly in contact with the liquid to be treated through the sealed tube 1 by being in close contact with the outer circumference of the sealed tube 1. . Thereby, since the sealing tube 1 is cooled by the to-be-processed liquid, corresponding cooling effect can be acquired without a special heat radiating fan or a heat sink. Of course, also in this case, in order to supplement a cooling effect, you may install a cooling fan (not shown) in the suitable location of the exterior of the sealed pipe 1. In that case, the fan may be a small fan, as long as it can be provided with a complementary cooling effect.

FIG. 4 shows an example in which an anodic thermally conductive adhesive 10 is sandwiched between the ballast 8 and the hermetic tube 1, and the adhesive 10 has good thermal conductivity as an example, for example, silicon, or the like. The adhesive which uses as a main component is used. In this case, when the bottom surface of the stabilizer 8 is flat and the outer circumference of the closed tube 1 is a curved surface, the flat bottom surface of this stabilizer 8 is connected to the curved surface of the outer circumference of the sealed tube 1 through the adhesive agent 10. The bottom surface of the stabilizer 8 and the outer circumferential surface of the hermetic pipe 1 can be brought into close contact with the curved surface of the outer circumference of the hermetic pipe 1 through a double heat-conductive adhesive 10 by mounting. The thermal conductivity can be satisfactorily maintained by the close contact with each other. Thereby, the heat of the ballast 8 can be radiated to the outer surface of the sealed tube 1 through the adhesive 10, and the cooling effect by indirectly contacting the liquid to be processed in the sealed tube 1 is sufficient. You can get it. In addition, when the bottom surface of the stabilizer 8 is a curved surface with the same curvature radius as the curved surface of the outer circumference of the hermetic pipe 1, the bottom surface of the stabilizer 8 is uniformly applied to the bottom surface of the stabilizer 8 by uniformly applying it. Can be brought into close contact with the curved surface of the outer circumference of the hermetic pipe 1 without a gap. Therefore, the cooling effect can be sufficiently obtained by indirectly contacting the liquid to be processed in the hermetic pipe 1.

FIG. 5 shows an example in which a double heat-conducting soft cushioning material 11 is sandwiched between the stabilizer 8 and the hermetic pipe 1. As the shock absorbing material 11, for example, a predetermined thickness is shown. The sheet-like thing of the elastic deformation | transformation-modifiable positive thermal conductivity which have is used. In this case, when the bottom surface of the stabilizer 8 is flat and the outer circumference of the closed tube 1 is a curved surface, the flat bottom surface of this stabilizer 8 is connected to the curved surface of the outer circumference of the sealed tube 1 through the buffer material 11. Since adhesion can be made without a gap, thermal conductivity can be satisfactorily maintained by adhesion between the entire bottom face of the ballast 8 and the curved surface of the outer circumference of the closed tube 1. Thereby, the heat of the ballast 8 can be radiated to the outer surface of the hermetic pipe 1 through the buffer 11, and the cooling effect can be sufficiently obtained by indirectly contacting the liquid to be processed in the hermetic pipe 1. Can be. When attaching the stabilizer 8 to the curved surface of the outer circumference of the sealed tube 1 via the buffer member 11, a double heat conductive adhesive is applied to the buffer member 11 or the sealed tube 1 is provided from the outside of the stabilizer 8. You may wind the belt around the outer surface of the Alternatively, the stabilizer 8 in which the shock absorbing material 11 is sandwiched between the outer surface of the sealed tube 1 may be attached to the outer surface of the sealed tube 1 by fitting or the like. As an example, as shown in FIG. 6, a pair of pedestals which oppose each of one side of the ballast 8 and the other side opposite to this one side at a predetermined location on the outer surface of the sealed tube 1 Iii) 12a and 12b are provided, and the stabilizer 8 is disposed between the pair of pedestals 12a and 12b through the shock absorbing material 11 on the outer surface of the sealed tube 1, and the stabilizer 8 One side of the L-shaped fittings 13a and 13b is mounted on one side and the other side of each other), while the other side of the L-shaped fittings 13a and 13b is screwed onto the corresponding pedestals 12a and 12b or Fixing is performed by suitable fixing means (such as screw fixing in the illustrated example) 14a and 14b, such as patching fixing. Thus, by attaching the ballast 8 to the outer periphery of the closed tube 1 by fitting, the flat bottom surface of the ballast 8 adheres closely to the curved surface of the outer periphery of the sealed tube 1 via the buffer material 11 without a gap. You can. In addition, the cushioning material 11 is not limited to an elastic body, and may use other positive thermally conductive substance (material with heat dissipation).

Next, another embodiment of the present invention will be described with reference to FIGS. 7 and 8. 7 is a schematic perspective view, and FIG. 8 is a partially enlarged sectional view. The cooling liquid tank 20 is closely fixed to the predetermined location of the outer side of the sealing tube 1 by means of welding, etc. The predetermined cooling liquid C is filled in this cooling liquid tank 20 liquid-tightly. The coolant tank 20 is made of metal having good thermal conductivity such as stainless steel and the like similarly to the hermetic pipe 1. The ballast box 21 is disposed in contact with the coolant tank 20, and the ballast 8 is disposed in the ballast box 21. The ballast 8 is fixed to the wall surface of the coolant tank 20 in the ballast box 21, and is cooled by the internal coolant C through the heat-conductive wall surface of the coolant tank 20. The cooling liquid C is heated once by taking heat from the ballast 8, but since the cooling liquid C is in close contact with the wall surface of the sealed tube 1, the cooling liquid C immediately flows by the liquid to be processed P flowing in the sealed tube 1. Is cooled. The cooling medium (i.e., heat dissipation medium) to be filled in the coolant tank 20 is not limited to a liquid, and may be gel or fixed, or may be a medium having a cooling effect (i.e., heat dissipation effect). As the cooling medium C, water or another predetermined cooling liquid or a substance having good heat exchange characteristics may be used. Of course, the ballast box 21 can be opened and closed appropriately, and the internal ballast 8 can be replaced, repaired, or the like. Of course, the number of ballasts 8 arranged in contact with the coolant tank 20 in the ballast box 21 is not limited to one, but the number of ultraviolet lamps provided in the sealed tube 1 is arranged. In addition, the operation panel 22 including a switch or the like may be disposed at a suitable location near the ballast box 21 (for example, at the end cover 6 of the closed tube 1 or on the side of the ballast box 21). Etc.). In that case, of course, the operation panel 22 and the ballast box 21 are appropriately connected by the electrical wiring which is not shown in figure.

As mentioned above, although some Example of this invention in the ultraviolet-ray liquid processing apparatus of a sealed tube installation type was demonstrated, this invention is not limited to this, The invention can be applied also to the ultraviolet liquid processing apparatus of an installation type by the number.

As described above, according to the present invention, since the ballast of the ultraviolet lamp is disposed close to the outer surface of the pipeline through the liquid to be treated, the ballast is not directly in contact with the liquid to be treated in the pipeline, but through the pipeline The heat dissipation of the ballast can be promoted by the cooling effect indirectly, so that the heat dissipation means of the ballast can be unnecessary, or the scale thereof can be reduced, and the size of the ballast can be miniaturized. In addition, the heat dissipation means of the ballast can be eliminated or the scale thereof can be reduced, thereby avoiding the necessity of the prior art that the ballast must be housed in the power box for the heat dissipation countermeasure. Since the ballast can be arranged on the side, the size of the power supply box can be made much smaller than the conventional one. Therefore, it is possible to provide an easy-to-use ultraviolet liquid processing apparatus and method that do not occupy an installation area of a power box and are easy to apply to a narrow installation place.
