Description

この発明は、マイクロ波給電式による無電極紫外線ランプを用いて、例えば微生物や有機物が懸濁あるいは溶存した状態にある水処理を行う場合に好適な紫外線照射装置に関する。   The present invention relates to an ultraviolet irradiation apparatus suitable for, for example, performing water treatment in which microorganisms or organic substances are suspended or dissolved using an electrodeless ultraviolet lamp of a microwave power feeding type.

従来から紫外線と光触媒の併用により、水質を改善させるための紫外線照射装置用光源としては、長寿命化を図ることから無電極紫外線ランプが用いられている。この紫外線照射装置は、無電極紫外線ランプと光触媒が流体改善区域外に設置されたマグネトロンから、流体改善区域内に配置された無電極紫外線ランプに対してマイクロ波を放射して紫外線を発光させ、その紫外線によってさらに光触媒による化学反応を促進させることで、流体の改善が行われている。（例えば、特許文献１）
特表２００５−５２４５２４公報 Conventionally, an electrodeless ultraviolet lamp has been used as a light source for an ultraviolet irradiation device for improving water quality by using a combination of ultraviolet rays and a photocatalyst in order to extend the life. This ultraviolet irradiation device emits ultraviolet rays by emitting microwaves from a magnetron in which an electrodeless ultraviolet lamp and a photocatalyst are installed outside the fluid improvement area to an electrodeless ultraviolet lamp arranged in the fluid improvement area, The fluid is improved by further promoting the chemical reaction by the photocatalyst by the ultraviolet rays. (For example, Patent Document 1)
JP 2005-524524 A

上記した特許文献１の技術は、紫外線を放射する無電極ランプが流体改善区域内に設置されていることから、無電極ランプを交換する場合には、流体や光触媒の中から無電極ランプ自体を取り出す必要がある。この場合、流体改善区域内の無電極ランプと流体改善区域外のマグネトロンの間に水が存在するため、マイクロ波が水に吸収されることから、効率よく無電極ランプに対してマイクロ波が放射されない、という問題があった。   In the technique of Patent Document 1 described above, since an electrodeless lamp that emits ultraviolet rays is installed in the fluid improvement zone, when replacing the electrodeless lamp, the electrodeless lamp itself is removed from the fluid or the photocatalyst. It is necessary to take it out. In this case, since water is present between the electrodeless lamp in the fluid improvement area and the magnetron outside the fluid improvement area, the microwave is absorbed by the water, so that the microwave is efficiently emitted to the electrodeless lamp. There was a problem that it was not.

この発明の目的は、無電極ランプの交換性の向上を図るとともに、効率よく無電極ランプにマイクロ波を放射させて流体改善の向上を図ることのできる紫外線照射装置を提供することにある。   An object of the present invention is to provide an ultraviolet irradiation device capable of improving the exchangeability of an electrodeless lamp and improving the fluid improvement by efficiently radiating microwaves to the electrodeless lamp.

上記した課題を解決するために、この発明の紫外線照射装置は、前記マイクロ波を発生させるためのマグネトロンと、紫外線を透過させる誘電体からなるとともに、前記マイクロ波による放電で紫外線を発光する物質が封入される管状の無電極ランプと、前記マイクロ波を前記無電極ランプに伝達する導波管と、少なくとも前記マグネトロン、無電極ランプ、導波管を内部に配置したランプハウスと、被処理水が収容され前記無電極ランプから発光する紫外線を光学的に通過させる照射窓が形成された収容部と、前記被処理水内の前記紫外線が照射される位置に配置した光触媒機能を備えた浄化処理部材と、を具備したことを特徴とする。   In order to solve the above-described problems, an ultraviolet irradiation device of the present invention includes a magnetron for generating a microwave and a dielectric that transmits ultraviolet light, and a substance that emits ultraviolet light by discharge by the microwave. An enclosed tubular electrodeless lamp, a waveguide for transmitting the microwave to the electrodeless lamp, a lamp house having at least the magnetron, electrodeless lamp, and waveguide disposed therein, and water to be treated A purification treatment member provided with a housing part in which an irradiation window for optically passing ultraviolet light that is received and emitted from the electrodeless lamp is formed, and a photocatalytic function disposed at a position where the ultraviolet light is irradiated in the water to be treated It was characterized by comprising.

この発明によれば、ランプハウス自体の着脱とランプ交換性が容易となることから、メンテナンが容易となり、ランニングコストの削減につなげることが可能となる。   According to the present invention, the lamp house itself can be easily attached and detached and the lamp can be exchanged. Therefore, maintenance is facilitated, and the running cost can be reduced.

以下、この発明を実施するための最良の形態について、図面を参照しながら詳細に説明する。   Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

図１〜図３は、この発明の紫外線照射装置に関する第１の実施形態について説明するための、図１はシステム構成について説明するための斜視図、図２は図１の断面図、図３はこの発明で用いる無電極ランプについて説明するための構成図である。   1 to 3 are diagrams for explaining a first embodiment of the ultraviolet irradiation apparatus of the present invention, FIG. 1 is a perspective view for explaining a system configuration, FIG. 2 is a sectional view of FIG. 1, and FIG. It is a block diagram for demonstrating the electrodeless lamp used by this invention.

図１、図２において、１１は、例えばステンレス製の四方形状のランプハウスであり、このランプハウス１１内の上方部には、マグネトロン１２を配置する。ランプハウス１１は、マグネトロン１２から発生されるマイクロ波を遮断する構造となっている。マグネトロン１２と対向するランプハウス１１の下方部には、電極を備えないいわゆる無電極ランプ１３を配置してある。   1 and 2, reference numeral 11 denotes a stainless steel square lamp house, for example, and a magnetron 12 is disposed in the upper part of the lamp house 11. The lamp house 11 has a structure that blocks microwaves generated from the magnetron 12. A so-called electrodeless lamp 13 having no electrode is disposed below the lamp house 11 facing the magnetron 12.

無電極ランプ１３は、図３に示す構成を備えている。すなわち、１３１は紫外光を透過させる石英ガラス製の長さが２００ｍｍ程度の円筒形状のバルブである。バルブ１３１は、長手方向の中央部１３２をその両端部１３３，１３４よりも細くなるようにテ―パをつけたもので、両端部１３３，１３４の外径は例えば１７ｍｍ程度、中央部１３２の外径は１２ｍｍ程度である。バルブ１３１の発光空間１３５内には、不活性ガスと水銀、それにタリウムとヨウ素を封入する。バルブ１３１の両端にはバルブ１３１を支持する支持部１３６，１３７を、バルブ１３１と一体的に形成する。   The electrodeless lamp 13 has the configuration shown in FIG. That is, 131 is a cylindrical bulb made of quartz glass that transmits ultraviolet light and has a length of about 200 mm. The valve 131 is formed by attaching a taper to the central portion 132 in the longitudinal direction so as to be thinner than both end portions 133 and 134. The outer diameter of both end portions 133 and 134 is about 17 mm, for example. The diameter is about 12 mm. An inert gas and mercury, and thallium and iodine are sealed in the light emitting space 135 of the bulb 131. Support portions 136 and 137 for supporting the valve 131 are formed integrally with the valve 131 at both ends of the valve 131.

図１、図２において、マグネトロン１２と無電極ランプ１３との間には、マグネトロン１２で発生したマイクロ波を送出させるアンテナ１４から、無電極ランプ１３に伝達させる導波管１５を配置する。また、マグネトロン１２と無電極ランプ１３との間には、無電極ランプ１３から照射される波長２００〜４００ｎｍの紫外線をランプハウス１１の下方側に反射させ、反射させた紫外線を拡散もしくは集光させるための反射鏡１６が配置されている。反射鏡１６はマイクロ波を通過させる例えば耐熱性の樹脂等で形成される。   In FIG. 1 and FIG. 2, between the magnetron 12 and the electrodeless lamp 13, a waveguide 15 for transmitting the microwave generated by the magnetron 12 to the electrodeless lamp 13 is disposed. Further, between the magnetron 12 and the electrodeless lamp 13, the ultraviolet rays having a wavelength of 200 to 400 nm irradiated from the electrodeless lamp 13 are reflected to the lower side of the lamp house 11, and the reflected ultraviolet rays are diffused or condensed. A reflecting mirror 16 is provided. The reflecting mirror 16 is formed of, for example, a heat resistant resin that allows microwaves to pass therethrough.

１７は、被処理水が収容されるランプハウス１１の空間とは別の空間とした箱状の収容部である。また、収容部１７は上面１７１がランプハウス１１の底部１１１とを兼用するもので、底部１１１に無電極ランプ１３で発光した紫外線を照射させるための照射窓１１２を形成することで、無電極ランプ１３と収容部１７は光学的に連通された状態の構造となる。   Reference numeral 17 denotes a box-shaped storage unit that is a space different from the space of the lamp house 11 in which the water to be treated is stored. The housing portion 17 has an upper surface 171 that also serves as the bottom portion 111 of the lamp house 11. By forming an irradiation window 112 for irradiating ultraviolet light emitted from the electrodeless lamp 13 on the bottom portion 111, an electrodeless lamp is formed. 13 and the accommodating part 17 become a structure of the state connected optically.

収容部１７の上面１７１（底部１１１）に形成された照射窓１１２の全面には、スクリーン１８が配置される。スクリーン１８は、例えば、金属線をメッシュ状に編み込んだり、金属板にパンチング加工したりすることにより形成される。   The screen 18 is disposed on the entire surface of the irradiation window 112 formed on the upper surface 171 (bottom portion 111) of the accommodating portion 17. The screen 18 is formed, for example, by braiding metal wires into a mesh shape or punching a metal plate.

さらに、照射窓１１２と対向する収容部１７内には、複数枚の浄化処理部材１９を無電極ランプ１３のランプ軸に対して、傾斜された状態で配置する。浄化処理部材１９は、例えば金属製の網や金属板に多孔を形成した基材の表面に、光触媒物質を担持させたものである。   Further, a plurality of purification treatment members 19 are arranged in an inclined state with respect to the lamp axis of the electrodeless lamp 13 in the housing portion 17 facing the irradiation window 112. The purification treatment member 19 is obtained by, for example, supporting a photocatalytic substance on the surface of a base material in which holes are formed in a metal net or a metal plate.

光触媒物質としては、紫外線の照射を受けることにより活性化されて被処理水に含まれる有機物を分解または変質させ得るものが用いられ、例えば二酸化チタン、特にアナタ―ゼ型の二酸化チタンが好適である。二酸化チタンは、紫外線が照射されることにより励起され、水を分解してＯＨラジカルを生成させる機能を有するものであり、生成されたＯＨラジカルにより、水中に含まれる有機物を分解または変質させる。光触媒物資を基材の表面に担持させる手段としては、例えば焼結処理により実現可能である。また、基材となる金属材料としては、光触媒物質を構成する金属元素と同種の元素よりなる金属材料が好ましく、例えば光触媒物質として酸化チタンを用いる場合には、チタンを用いることが好ましい。   As the photocatalytic substance, a substance that can be activated by being irradiated with ultraviolet rays and decompose or alter organic substances contained in the water to be treated is used. For example, titanium dioxide, particularly anatase type titanium dioxide is preferable. . Titanium dioxide is excited by irradiation with ultraviolet rays and has a function of decomposing water to generate OH radicals, and decomposes or alters organic substances contained in water by the generated OH radicals. The means for supporting the photocatalyst material on the surface of the substrate can be realized by, for example, a sintering process. Further, as the metal material to be the base material, a metal material made of the same element as the metal element constituting the photocatalytic substance is preferable. For example, when titanium oxide is used as the photocatalytic substance, it is preferable to use titanium.

ここで、図４を参照し、図１の右側面がら見た状態の側面図に図１を駆動させる機能を追加状態について説明する。   Here, with reference to FIG. 4, the function of driving FIG. 1 to the side view of the state seen from the right side of FIG.

図４において、反射鏡１６の前面に位置するランプハウス１１の側面には、無電極ランプ１３から発光する紫外線を受光する受光素子４１と、受光素子４１が受光した光の量を検出する光量検出器４２と、予め光の量が設定され、光量検出器４２により検出された光の量が、設定された光の量に等しくなるように電源４４を制御する電源制御部４３を備える。受光素子４１は、紫外線照射の妨げにならないように、反射鏡１６とスクリーン１８を結ぶ直線上を避けて設けられている。   In FIG. 4, on the side surface of the lamp house 11 positioned in front of the reflecting mirror 16, a light receiving element 41 that receives ultraviolet light emitted from the electrodeless lamp 13 and a light amount detection that detects the amount of light received by the light receiving element 41. And a power controller 43 for controlling the power source 44 so that the amount of light is set in advance and the amount of light detected by the light amount detector 42 is equal to the set amount of light. The light receiving element 41 is provided avoiding a straight line connecting the reflecting mirror 16 and the screen 18 so as not to hinder ultraviolet irradiation.

このようにして、収容部１７に収容された被処理水は、無電極ランプ１３で発光する紫外線を被処理水中に配置された浄光触媒物質が担持の浄化処理部材１９に照射することにより、被処理水に含まれる有機物を分解または変質させ、被処理水の改善を図ることができる。   In this way, the water to be treated accommodated in the accommodating portion 17 is irradiated with ultraviolet light emitted from the electrodeless lamp 13 to the purification treatment member 19 supported by the light purification catalyst substance arranged in the water to be treated. The organic matter contained in the treated water can be decomposed or altered to improve the treated water.

この実施形態では、無電極ランプ１３はマグネトロン１２と同じランプハウス１１内に配置され、被処理水を収容する収容部１７とは別空間に分けてある。このため、ランプハウス１１自体の取り外しと無電極ランプ１３の交換が容易となり、メンテナンス性の向上に繋がり、ランニングコストの削減に寄与する。   In this embodiment, the electrodeless lamp 13 is disposed in the same lamp house 11 as the magnetron 12, and is divided into a separate space from the accommodating portion 17 that accommodates the water to be treated. For this reason, removal of the lamp house 11 itself and replacement of the electrodeless lamp 13 are facilitated, leading to improvement in maintainability and contributing to reduction in running cost.

図５は、この発明の紫外線照射装置に関する第２の実施形態について説明するための構成図である。上記した実施形態と同一構成部分には同一の符号を付してここでは異なる部分について説明する。   FIG. 5 is a block diagram for explaining a second embodiment relating to the ultraviolet irradiation apparatus of the present invention. The same components as those in the above-described embodiment are denoted by the same reference numerals, and different portions will be described here.

この実施形態は、浄化処理部材１９２を無電極ランプ１３のランプ軸に対して平行に配置したものである。この場合は、スクリーン１８を介して照射される紫外線が、傾斜した場合に比べて広い面積となる。このため浄化処理部材１９２の処理能力の向上に寄与する。   In this embodiment, the purification treatment member 192 is arranged in parallel to the lamp axis of the electrodeless lamp 13. In this case, the ultraviolet rays irradiated through the screen 18 have a larger area than when tilted. For this reason, it contributes to the improvement of the processing capability of the purification processing member 192.

この場合も、無電極ランプとマグネトロンが一体のランプハウスに配置し、被処理水が収容する空間とは別の空間であるため、ランプハウス自体の取り外しとランプ交換性の向上を図ることができる。   Also in this case, since the electrodeless lamp and the magnetron are arranged in an integral lamp house and the space is different from the space in which the water to be treated is accommodated, the lamp house itself can be removed and the lamp exchangeability can be improved. .

図６は、この発明の紫外線照射装置に関する第３の実施形態について説明するための構成図である。上記した実施形態と同一構成部分には同一の符号を付してここでは異なる部分について説明する。   FIG. 6 is a block diagram for explaining a third embodiment relating to the ultraviolet irradiation apparatus of the present invention. The same components as those in the above-described embodiment are denoted by the same reference numerals, and different portions will be described here.

この実施形態は、浄化処理部材１９３を無電極ランプ１３のランプ軸に対して平行に配置することに加え、浄化処理部材１９３を波型としたものである。この場合は、スクリーン１８を介して照射される紫外線が、平面型の第２の実施形態に比べてさらに広い面積となる。このため浄化処理部材１９３の処理能力のさらに向上させることができる。   In this embodiment, in addition to disposing the purification treatment member 193 parallel to the lamp axis of the electrodeless lamp 13, the purification treatment member 193 has a wave shape. In this case, the ultraviolet rays irradiated through the screen 18 have a wider area than in the planar second embodiment. For this reason, the processing capability of the purification treatment member 193 can be further improved.

この場合も、無電極ランプとマグネトロンが一体のランプハウスに配置し、被処理水が収容する空間とは別の空間であるため、ランプハウス自体の取り外しとランプ交換性の向上を図ることができる。   Also in this case, since the electrodeless lamp and the magnetron are arranged in an integral lamp house and the space is different from the space in which the water to be treated is accommodated, the lamp house itself can be removed and the lamp exchangeability can be improved. .

図７、図８は、この発明の紫外線照射装置に関する第４の実施形態について説明するためのもので、図７は図２に相当する構成図、図８は図７の要部を拡大して示した斜視図である。上記した各実施形態と同一構成部分には同一の符号を付してここでは異なる部分について説明する。   7 and 8 are for explaining a fourth embodiment relating to the ultraviolet irradiation apparatus of the present invention. FIG. 7 is a block diagram corresponding to FIG. 2, and FIG. 8 is an enlarged view of the main part of FIG. It is the shown perspective view. The same components as those in the above-described embodiments are denoted by the same reference numerals, and different portions will be described here.

図７、図８において、収容部１７（ランプハウス１１）の一部を、マイクロ波を送出させるための導波管１５と兼用するとともに、導波管１５を収容部１７の位置に配置するようにした。すなわち、収容部１７の上面１７１に切込みを入れ、ここから収容部１７の内部側にほぼ直角に折りこんで切込み部７１，７２を形成し、取付け孔７３をとする。折込み部７１，７２の端部には、ほぼ円筒状のスクリーン１８２を取り付ける。スクリーン１８２は、折込み部７１と７２の間隔だけスクリーン１８２の長手方向に切欠部７４を形成し、この切欠部７４を折込部７１，７２の端部を接着等の接合手段を用いて取着する。これにより、スクリーン１８２の内部は、切欠部７４と取付け孔７３を介して収容部１７の外部と連通した状態となる。   7 and 8, a part of the accommodating portion 17 (lamp house 11) is also used as the waveguide 15 for sending microwaves, and the waveguide 15 is arranged at the position of the accommodating portion 17. I made it. That is, a cut is made in the upper surface 171 of the housing part 17, and the cut parts 71, 72 are formed by folding at a substantially right angle from the inside to the inside of the housing part 17. A substantially cylindrical screen 182 is attached to the ends of the folding portions 71 and 72. The screen 182 forms a notch 74 in the longitudinal direction of the screen 182 by an interval between the folds 71 and 72, and the notch 74 is attached to the ends of the folds 71 and 72 using a bonding means such as adhesion. . As a result, the inside of the screen 182 is in communication with the outside of the housing portion 17 through the notch portion 74 and the attachment hole 73.

スクリーン１８２の内部には、無電極ランプ１３を配置して取り付ける。無電極ランプ１３の取付けは、無電極ランプ１３の支持部１３６，１３７を、図示しない収容部１７の取付け部に取り付けるか、取付け孔７３から無電極ランプ１３が取付けられた図示しない着脱式のランプ取付具を収納するかにより実現できる。また、スクリーン１８２の内部は防水構造とし、収容部１７内の被処理水が入り込まないようにしてある。   An electrodeless lamp 13 is disposed and attached inside the screen 182. The electrodeless lamp 13 is attached by attaching the support portions 136 and 137 of the electrodeless lamp 13 to an attachment portion of the housing portion 17 (not shown) or a detachable lamp (not shown) in which the electrodeless lamp 13 is attached from the attachment hole 73. This can be realized by storing the fixture. Further, the inside of the screen 182 has a waterproof structure so that water to be treated in the housing portion 17 does not enter.

これにより、無電極ランプ１３は、円筒形状に形成された浄化処理部材１９４内に配置する状態に配置される。浄化処理部材１９４は、径の異なるものを用意し、スクリーン１８２の周囲を取り囲む格好としている。この例では、浄化処理部材１９４を２重に配置してある。   Thereby, the electrodeless lamp 13 is arrange | positioned in the state arrange | positioned in the purification process member 194 formed in the cylindrical shape. The purification processing member 194 is prepared so as to have different diameters and surrounds the screen 182. In this example, the purification treatment members 194 are arranged in a double manner.

この場合、マイクロ波を送出する導波管１５を、収容部１７内に配置された無電極ランプ１３の発光部まで設置したことで、あたかも収容部１７内からの発光であるかのような紫外線照射が可能となり、浄化処理部材１９に対する紫外線の照射効率を向上させることができる。   In this case, the waveguide 15 for transmitting the microwaves is installed up to the light emitting part of the electrodeless lamp 13 disposed in the accommodating part 17, so that the ultraviolet rays as if the light is emitted from the accommodating part 17. Irradiation becomes possible, and the irradiation efficiency of the ultraviolet rays to the purification treatment member 19 can be improved.

また、直径の異なる複数の円筒形状の浄化処理部材１９は、無電極ランプ１３に対して取り囲む構造をしていることから、反射鏡なしに確実に効率よく無電極ランプ１３から照射される紫外線を受けることが可能となる。   Further, since the plurality of cylindrical purification treatment members 19 having different diameters have a structure surrounding the electrodeless lamp 13, the ultraviolet rays irradiated from the electrodeless lamp 13 can be reliably and efficiently emitted without a reflecting mirror. It becomes possible to receive.

この実施形態では、無電極ランプをランプハウス側から交換可能としながら、無電極ランプを囲む格好で浄化処理部材を配置できることから、浄化処理部材に確実に紫外線を照射させることができる。   In this embodiment, since the electrodeless lamp can be replaced from the lamp house side, the purification treatment member can be arranged in a manner that surrounds the electrodeless lamp, so that the purification treatment member can be reliably irradiated with ultraviolet rays.

この発明は、上記した実施形態に限定されるものではない。例えば、被処理水は収容部１７内で被処理水に含まれる有機物を分解または変質させるようにしたが、被処理水はダクトを用いて連続的に処理することも考えられる。   The present invention is not limited to the above-described embodiment. For example, the water to be treated is decomposed or denatured in the accommodating portion 17 and the organic matter contained in the water to be treated is treated, but the water to be treated may be continuously treated using a duct.

また、収容部１７の重なるランプハウス１１の部分は、収容部１７で兼用したが、それぞれ形成して結合しても構わない。   Moreover, although the part of the lamp house 11 with which the accommodating part 17 overlaps was shared by the accommodating part 17, you may form and connect, respectively.
