Description
本発明は、燃料電池システム等に利用される水処理装置に関するものである。 The present invention relates to a water treatment device used for a fuel cell system or the like.
従来、水処理装置は、貯水槽に貯えられた水をポンプ等の水汲み上げ手段により汲み上げた後、イオン交換樹脂等で構成されるイオン交換装置を介してイオン成分を取り除き浄化処理するものである（例えば、特許文献１参照）。特許文献１を参酌し、このような水処理装置の一般的な構成を説明する。 Conventionally, a water treatment apparatus is for purifying water stored in a water tank by removing ion components through an ion exchange apparatus composed of an ion exchange resin or the like after pumping up water by a water pumping means such as a pump. (For example, refer to Patent Document 1). With reference to Patent Document 1, a general configuration of such a water treatment apparatus will be described.
図６は、特許文献１に記載された従来の燃料電池システムに搭載された水処理装置の概略を示した構成図である。 FIG. 6 is a configuration diagram showing an outline of a water treatment device mounted on a conventional fuel cell system described in Patent Document 1.
図６において、貯水槽６５から送水ポンプ６６により汲み上げられた水は、イオン交換装置６９を介して浄化された後、冷却水タンク６１０に貯水される。ここで、イオン交換装置６９の前段には、貯水槽６５から送水ポンプ６６を介してイオン交換装置６９に至る水処理経路において、菌類の増殖を抑止する目的で、抗菌フィルター６７と紫外線装置６８が配置される。イオン交換装置６９で浄化された水は、一旦冷却水タンク６１０に貯水され、冷却水タンク６１０から、循環ポンプ６１０により水が汲み出され、燃料電池６１を循環し、燃料電池６１を一定温度に保っている。また、冷却水タンク６１０からは、送水ポンプ６１２により水が汲み出され、燃料ガス生成装置６３において、都市ガスを改質し水素を発生させるための水として使用される。 In FIG. 6, the water pumped up from the water storage tank 65 by the water pump 66 is purified through the ion exchange device 69 and then stored in the cooling water tank 610. Here, an antibacterial filter 67 and an ultraviolet ray device 68 are provided in the preceding stage of the ion exchange device 69 for the purpose of inhibiting the growth of fungi in the water treatment path from the water storage tank 65 to the ion exchange device 69 via the water pump 66. Be placed. The water purified by the ion exchange device 69 is temporarily stored in the cooling water tank 610, pumped out from the cooling water tank 610 by the circulation pump 610, circulated through the fuel cell 61, and the fuel cell 61 is kept at a constant temperature. I keep it. Further, water is pumped out from the cooling water tank 610 by a water pump 612 and used as water for reforming the city gas and generating hydrogen in the fuel gas generator 63.
ここで、燃料電池６１は、燃料ガス生成装置６３からの水素と、空気供給装置６２からの空気の供給を受けて発電し、燃料電池６１から排出される排空気が熱交換器６４に送られ、その中に含まれる水蒸気から水が分離され、分離された水が貯水槽６５に回収される。 Here, the fuel cell 61 receives the supply of hydrogen from the fuel gas generation device 63 and the air from the air supply device 62 to generate power, and exhaust air discharged from the fuel cell 61 is sent to the heat exchanger 64. The water is separated from the water vapor contained therein, and the separated water is collected in the water storage tank 65.
しかしながら、前記従来の構成では、貯水槽６５から送水ポンプ６６を介してイオン交換装置６９に至る水処理経路において、菌類の増殖を抑える手段として万全でなく、当該水処理経路において、菌類の増殖による閉塞が発生し、長期に亘り安定な流量を確保できないという課題があった。 However, in the conventional configuration, in the water treatment path from the water storage tank 65 to the ion exchange device 69 via the water pump 66, it is not a perfect means for suppressing the growth of fungi. There was a problem that blockage occurred and a stable flow rate could not be secured over a long period of time.
すなわち、図６の構成では、抗菌フィルター６７を設置した場所や紫外線装置６８により紫外線が照射される場所においては、菌類の増殖を抑止できるが、抗菌フィルター６７や紫外線装置６８で殺菌処理されずに生き残った菌類は、抗菌フィルター６７や紫外線装置６８と離れた場所において増殖し、結局のところ、水処理経路において、菌類の増殖による閉塞を引き起こすという課題があった。また、抗菌フィルター６７には、一般的には粒子状の抗菌剤が使用されるため、抗菌フィルター６７から抗菌剤が遊離し、抗菌剤自体が、水処理経路を閉塞するという課題があった。 That is, in the configuration of FIG. 6, the growth of fungi can be suppressed at the place where the antibacterial filter 67 is installed or where the ultraviolet ray is irradiated by the ultraviolet ray device 68, but without being sterilized by the antibacterial filter 67 or the ultraviolet ray device 68. The surviving fungi grew at a place away from the antibacterial filter 67 and the ultraviolet device 68, and eventually, there was a problem of causing clogging due to the growth of fungi in the water treatment route. Further, since a particulate antibacterial agent is generally used for the antibacterial filter 67, the antibacterial agent is released from the antibacterial filter 67, and the antibacterial agent itself has a problem of blocking the water treatment path.
本発明は、上記課題を考慮し、燃料電池システム等に利用される水処理装置において、
より効率的に菌類の増殖によって発生する水処理経路での閉塞を回避できる手段を提供し、長期に亘って安定な流量を確保し得る水処理装置を提供することを目的とする。
In consideration of the above problems, the present invention provides a water treatment device used for a fuel cell system or the like,
An object of the present invention is to provide a means for avoiding blockage in a water treatment path generated by fungal growth more efficiently, and to provide a water treatment apparatus capable of ensuring a stable flow rate over a long period of time.
従来の課題を解決するために、本発明の水処理装置は、水タンクの内部に配置され、水に含まれる菌類を積極的に捕捉する菌類捕捉手段を具備し、燃料電池発電装置で発生した凝縮水が、前記菌類捕捉手段と接触した後、水タンクに貯える構成としたものである。 In order to solve the conventional problems, the water treatment apparatus of the present invention is provided inside the water tank, and has fungus capturing means for actively capturing fungi contained in the water, and is generated in the fuel cell power generation apparatus. The condensed water is configured to be stored in a water tank after contacting the fungus capturing means.
これによって、燃料電池発電装置から排出される排空気等から回収した凝縮水に含まれる菌類が菌類捕捉手段において積極的に捕捉されることになるため、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において、菌類の増殖を抑止できることになる。その結果、水処理経路における菌類の繁殖による閉塞が回避でき、長期に亘り安定な流量を確保できることになる。 As a result, the fungi contained in the condensed water recovered from the exhaust air discharged from the fuel cell power generation device are actively captured by the fungus capturing means, so the ion exchange device from the water storage tank via the water pump In the water treatment route leading to, the growth of fungi can be suppressed. As a result, blockage due to fungal growth in the water treatment path can be avoided, and a stable flow rate can be secured over a long period of time.
また、本発明の燃料電池システムは、菌類捕捉手段が水に含まれる有機物を吸着する有機物吸着手段（以下、有機物をＴＯＣ、有機物吸着手段をＴＯＣ吸着手段という）を具備し、燃料電池発電装置で発生した凝縮水が、前記ＴＯＣ吸着手段と接触した後、水タンクに貯える構成としたものである。 In addition, the fuel cell system of the present invention includes an organic substance adsorbing means (hereinafter referred to as TOC, organic substance adsorbing means is referred to as TOC adsorbing means) in which the fungus capturing means adsorbs organic substances contained in water. The generated condensed water is configured to be stored in a water tank after contacting the TOC adsorbing means.
これによって、ＴＯＣ吸着手段が、燃料電池発電装置から排出される排空気等から回収した凝縮水の中に含まれるＴＯＣを積極的に吸着することができるため、ＴＯＣ吸着手段がＴＯＣが豊富な状態になる。そして、ＴＯＣ吸着手段に吸着された豊富なＴＯＣを栄養源にして、凝縮水中に含まれる菌類が菌類捕捉手段において積極的に捕捉されることになる。また、凝縮水の中に含まれるＴＯＣは、ＴＯＣ吸着手段で積極的に吸着されるため、ＴＯＣ吸着手段ないし菌類捕捉手段の後段に配置される貯水槽や、当該貯水槽から送水ポンプを介してイオン交換装置に至る経路において、ＴＯＣの濃度が低下するため、菌類にとっては貧栄養状態となり、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において、菌類の増殖を抑止できることになる。その結果、水処理経路における菌類の繁殖による閉塞が回避でき、長期に亘り安定な流量を確保できることになる。 As a result, the TOC adsorbing means can actively adsorb TOC contained in the condensed water recovered from the exhaust air discharged from the fuel cell power generator, so that the TOC adsorbing means is rich in TOC. become. Then, the fungi contained in the condensed water are positively captured by the fungus capturing means using the abundant TOC adsorbed by the TOC adsorbing means as a nutrient source. Moreover, since the TOC contained in the condensed water is actively adsorbed by the TOC adsorbing means, a water storage tank disposed downstream of the TOC adsorbing means or the fungus capturing means, or a water pump from the water storage tank via the water pump Since the TOC concentration decreases in the path leading to the ion exchange apparatus, the fungus becomes poorly eutrophic, and the growth of the fungus can be suppressed in the water treatment path from the water tank to the ion exchange apparatus via the water pump. . As a result, blockage due to fungal growth in the water treatment path can be avoided, and a stable flow rate can be secured over a long period of time.
また、本発明の燃料電池システムは、ＴＯＣ吸着手段が、活性炭を具備する構成としたものである。 In the fuel cell system of the present invention, the TOC adsorption means includes activated carbon.
これによって、ＴＯＣ吸着手段としての活性炭が、より効果的にＴＯＣを吸着できるため、菌類捕捉手段での菌類の捕捉をより促進でき、また、水処理経路におけるＴＯＣの濃度をより低減できるので、水処理経路における菌類の繁殖をより効率的に抑えることができる。これは、活性炭の表面は多くの極性官能基が存在し、ＴＯＣとの親和力が高く、より高いＴＯＣ吸着効果を発揮できるためである。 As a result, activated carbon as the TOC adsorbing means can adsorb TOC more effectively, so that the capture of fungi in the fungus capturing means can be further promoted, and the concentration of TOC in the water treatment path can be further reduced. Propagation of fungi in the treatment path can be more efficiently suppressed. This is because the surface of the activated carbon has many polar functional groups, has a high affinity with TOC, and can exhibit a higher TOC adsorption effect.
また、本発明の燃料電池システムは、菌類捕捉手段が開口部を具備し、燃料電池発電装置で発生した凝縮水が、菌類捕捉手段またはＴＯＣ吸着手段と接触した後、菌類捕捉手段の開口部を介して、水タンクの貯水部に貯水される構成としたものである。 Further, in the fuel cell system of the present invention, the fungus trapping means has an opening, and the condensed water generated in the fuel cell power generator comes into contact with the fungus trapping means or the TOC adsorbing means, and then the fungus trapping means has an opening. The water is stored in the water storage part of the water tank.
これによって、貯水槽に流れ込む凝縮水が、常に菌類捕捉手段やＴＯＣ吸着手段と接触するため、その中に含まれる菌類が菌類捕捉手段で捕捉されることになり、また、その中に含まれるＴＯＣがＴＯＣ吸着手段に吸着されることから、ＴＯＣ吸着手段のＴＯＣ濃度を経時的に向上させることができ、その結果、ＴＯＣ吸着手段を富栄養状態を促進することができる。また、ＴＯＣ濃度が低減された凝縮水が開口部を通じて貯水槽に貯水されることになるため、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において、菌類にとって貧栄上状態を促進することができるため、水処理経路における菌類の繁
殖を効率的に抑えることができる。
As a result, the condensed water flowing into the water storage tank always comes into contact with the fungus capturing means and the TOC adsorbing means, so that the fungi contained therein are captured by the fungus capturing means, and the TOC contained therein Is adsorbed by the TOC adsorbing means, the TOC concentration of the TOC adsorbing means can be improved with time, and as a result, the TOC adsorbing means can be promoted to a rich state. In addition, since the condensed water having a reduced TOC concentration is stored in the water storage tank through the opening, in the water treatment path from the water storage tank to the ion exchange device through the water pump, it is in a poor state for fungi. Since it can accelerate | stimulate, the propagation of the fungi in a water treatment path | route can be suppressed efficiently.
また、本発明の燃料電池システムは、菌類捕捉手段の開口部が、その口径が菌類の大きさより小さい細穴を有して構成されるものである。 In the fuel cell system of the present invention, the opening of the fungus capturing means has a narrow hole whose diameter is smaller than the size of the fungus.
これによって、菌類が、菌類捕捉手段の開口部に設けた細穴を通過することができないため、貯水槽に菌類が進入するのを遮断でき、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路における菌類の繁殖をより効率的に抑えることができる。 As a result, the fungi cannot pass through the narrow hole provided in the opening of the fungus capturing means, so that the fungi can be blocked from entering the water storage tank and reach the ion exchange device from the water storage tank via the water pump. Propagation of fungi in the water treatment route can be suppressed more efficiently.
また、本発明の燃料電池システムは、菌類捕捉手段が、ＴＯＣ吸着手段を加熱する加熱手段を具備して構成されるものである。 In the fuel cell system of the present invention, the fungus capturing means includes a heating means for heating the TOC adsorption means.
これによって、ＴＯＣ吸着手段で捕捉された菌類を熱殺菌できるため、菌類捕捉手段において菌類が無制限に増殖するのを抑止できる。 Thereby, since the fungi captured by the TOC adsorbing means can be thermally sterilized, it is possible to prevent the fungi from growing unlimitedly in the fungus capturing means.
また、本発明の燃料電池システムは、菌類捕捉手段が、水タンクから脱着可能なように配置されるものである。 In the fuel cell system of the present invention, the fungus trapping means is arranged so as to be detachable from the water tank.
これによって、菌類捕捉手段を定期的に取り替えることができるため、より長期に亘り安定な流量を確保できる水処理装置が実現できる。 Thereby, since the fungus-capturing means can be periodically replaced, a water treatment apparatus that can secure a stable flow rate for a longer period can be realized.
また、本発明の燃料電池システムは、水タンクが、菌類捕捉手段の最下段の高さより低い位置に、凝縮水を排水できる排水口を有して構成されるものである。 Further, the fuel cell system of the present invention is configured such that the water tank has a drain outlet that can drain condensed water at a position lower than the lowest height of the fungus capturing means.
これによって、貯水槽において余剰となった貯水を排水口を介して、貯水槽の外部に排水できるため、菌類捕捉手段が貯水槽に溜まった貯水で水没するのを回避でき、菌類捕捉手段から菌類が貯水中に流出するのを防止できる。 As a result, surplus water in the water storage tank can be drained to the outside of the water storage tank through the drain port, so that the fungus capturing means can be prevented from being submerged in the water stored in the water tank, and the fungus capturing means Can be prevented from flowing into the reservoir.
本発明の水処理装置は、水処理経路においておける菌類の繁殖を抑えることができ、したがって、長期に亘り安定な流量を確保し得る水処理装置が実現できる。 The water treatment apparatus of the present invention can suppress the growth of fungi in the water treatment path, and thus can realize a water treatment apparatus that can secure a stable flow rate over a long period of time.
第１の発明は、水を貯える水タンクと、水タンクから水をくみ出す水汲み出し手段と、その汲み出された水を浄化するイオン交換手段と、水タンクの内部に配置され水に含まれる菌類を捕捉する菌類捕捉手段と、燃料電池発電装置とを具備し、燃料電池発電装置で発生した凝縮水が、菌類捕捉手段と接触した後、水タンクに貯えられる水処理装置であり、この構成により、菌類捕捉手段が、燃料電池発電装置から排出される排空気等から回収した凝縮水に含まれる菌類を積極的に捕捉することができるため、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において、菌類の増殖を抑止できることになる。その結果、水処理経路における菌類の繁殖による閉塞が回避でき、長期に亘り安定な流量を確保できることになる。 The first invention includes a water tank for storing water, water pumping means for pumping water from the water tank, ion exchange means for purifying the pumped water, and water disposed in the water tank. A water treatment apparatus comprising a fungus capturing means for capturing fungi and a fuel cell power generation device, wherein the condensed water generated in the fuel cell power generation device is contacted with the fungus capture means and then stored in a water tank. Thus, the fungus capturing means can actively capture the fungi contained in the condensed water collected from the exhaust air discharged from the fuel cell power generator, so that the ion exchange device can be transferred from the water storage tank to the ion exchange device via the water pump. In the water treatment route to reach, fungus growth can be suppressed. As a result, blockage due to fungal growth in the water treatment path can be avoided, and a stable flow rate can be secured over a long period of time.
第２の発明は、特に、第１の発明の、菌類捕捉手段を、水に含まれるＴＯＣを吸着するＴＯＣ吸着手段を具備して構成し、燃料電池発電装置で発生した凝縮水が、ＴＯＣ吸着手段と接触した後、水タンクに貯えられる水処理装置であり、この構成により、ＴＯＣ吸着手段が、燃料電池発電装置から排出される排空気等から回収した凝縮水に含まれるＴＯＣを積極的に吸着することができるため、ＴＯＣ吸着手段において、ＴＯＣが豊富な状態になる。そして、ＴＯＣ吸着手段に吸着された豊富なＴＯＣを栄養源にして、凝縮水中に含まれる菌類が菌類捕捉手段において積極的に捕捉することができるようになる。また、凝縮水の中に含まれるＴＯＣはＴＯＣ吸着手段で積極的に吸着されるため、ＴＯＣ吸着手段ないし菌類捕捉手段の後段に配置される貯水槽や、当該貯水槽から送水ポンプを介してイオン交換装置に至る経路において、ＴＯＣの濃度が低下するため、菌類にとっては貧栄養状態となるため、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において、菌類の増殖を抑止できることになる。その結果、水処理経路における菌類の繁殖による閉塞が回避でき、長期に亘り安定な流量を確保できることになる。 In the second invention, in particular, the fungus-capturing means of the first invention comprises a TOC adsorbing means for adsorbing TOC contained in water, and the condensed water generated in the fuel cell power generator is TOC adsorbed. This is a water treatment device that is stored in a water tank after coming into contact with the means. With this configuration, the TOC adsorbing means positively collects the TOC contained in the condensed water recovered from the exhaust air discharged from the fuel cell power generation device. Since it can adsorb | suck, in a TOC adsorption | suction means, it will be in a state with abundant TOC. The fungi contained in the condensed water can be positively captured by the fungus capturing means using the abundant TOC adsorbed by the TOC adsorbing means as a nutrient source. Further, since the TOC contained in the condensed water is positively adsorbed by the TOC adsorbing means, a water tank disposed downstream of the TOC adsorbing means or the fungus capturing means, or ions from the water tank via the water pump Since the TOC concentration decreases in the path leading to the exchange device, the fungus is in an eutrophic state. Therefore, it is possible to suppress the growth of fungi in the water treatment path from the water storage tank to the ion exchange device via the water pump. Become. As a result, blockage due to fungal growth in the water treatment path can be avoided, and a stable flow rate can be secured over a long period of time.
第３の発明は、特に、第２の発明のＴＯＣ吸着手段を、活性炭を具備して構成することで、ＴＯＣ吸着手段としての活性炭が、その表面に多くの極性官能基を有し、より高いＴＯＣ吸着能力が発揮できるため、より効果的にＴＯＣを吸着でき、その結果、菌類繁殖手段での菌類の捕捉をより促進できる。また、水処理経路におけるＴＯＣ濃度をより低減できるので、水処理経路における菌類の繁殖をより効率的に抑えることができる。 In the third invention, in particular, the TOC adsorbing means of the second invention is configured by including activated carbon, so that the activated carbon as the TOC adsorbing means has many polar functional groups on its surface, and is higher. Since the TOC adsorption ability can be exhibited, TOC can be more effectively adsorbed, and as a result, the capture of fungi by the fungus breeding means can be further promoted. Moreover, since the TOC density | concentration in a water treatment path | route can be reduced more, propagation of the fungi in a water treatment path | route can be suppressed more efficiently.
第４の発明は、特に、第２または第３の発明において、菌類捕捉手段を開口部を具備して構成し、燃料電池発電装置で発生した凝縮水が、菌類捕捉手段またはＴＯＣ吸着手段と接触した後、菌類捕捉手段の開口部を介して、水タンクの貯水部に貯水される構成とすることで、貯水槽に流れ込む凝縮水が、常に菌類捕捉手段またはＴＯＣ吸着手段と接触するため、その中に含まれる菌類が菌類捕捉手段に捕捉され、また、その中に含まれるＴＯＣがＴＯＣ吸着手段に吸着されることなりＴＯＣ吸着手段におけるＴＯＣ濃度を経時的に向上させることができ、その結果、ＴＯＣ吸着手段の富栄養状態を促進することができる。また、ＴＯＣ濃度が低減された凝縮水が開口部を通じて貯水槽に貯水されることになるため、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において貧栄養状態を促進することができる。その結果、水経路における菌類の繁殖に伴う閉塞を防止できる。 In particular, according to a fourth aspect of the present invention, in the second or third aspect of the present invention, the fungus trapping means includes an opening, and the condensed water generated in the fuel cell power generator contacts the fungus trapping means or the TOC adsorbing means.

The fungi contained therein are captured by the fungus capturing means, and the TOC contained therein is adsorbed by the TOC adsorbing means, so that the TOC concentration in the TOC adsorbing means can be improved over time. The eutrophic state of the TOC adsorption means can be promoted. In addition, since condensed water with reduced TOC concentration is stored in the water storage tank through the opening, it is possible to promote an oligotrophic state in the water treatment path from the water storage tank to the ion exchange device via the water pump. it can. As a result, it is possible to prevent clogging associated with fungal growth in the water path.

まず、送水ポンプ１２により、貯水槽１１に貯えられた水が汲み上げられ、イオン交換装置１３に送られ、その水の中に含まれるイオン成分が除去され、冷却水槽１９に貯水される。冷却水槽１９からは、冷却水循環ポンプ１１０によって、冷却水が燃料電池発電装置１１１を循環し、燃料電池発電装置１１１を一定の温度に保つ。燃料電池発電装置１１１から排出される、排空気及び排燃料ガスは、それぞれ、空気側熱交換器１１２と燃料側熱交換器１１３に送られ、排空気及び排燃料ガスに含まれる水蒸気から水が回収され、凝縮水として、貯水槽１１の上部から菌類捕捉手段１６のＴＯＣ吸着手段１４としての活性炭の上に落下する。その後、ＴＯＣ吸着手段１４としての活性炭と接触した凝縮水は、菌類捕捉手段１６の支持板１５に設けた開口部１７を通って、貯水槽１１に貯水される。また、貯水槽１１において、貯水の水位が所定量になった場合、貯水槽１１の側面に設けた排水口１８から余剰の貯水が排水される。 First, the water stored in the water storage tank 11 is pumped up by the water pump 12, sent to the ion exchange device 13, ion components contained in the water are removed, and the water is stored in the cooling water tank 19. From the cooling water tank 19, the cooling water circulates through the fuel cell power generation device 111 by the cooling water circulation pump 110 to keep the fuel cell power generation device 111 at a constant temperature. Exhaust air and exhaust fuel gas discharged from the fuel cell power generator 111 are respectively sent to the air-side heat exchanger 112 and the fuel-side heat exchanger 113, and water is supplied from water vapor contained in the exhaust air and exhaust fuel gas. It is recovered and falls as condensed water onto the activated carbon as the TOC adsorbing means 14 of the fungus capturing means 16 from the upper part of the water storage tank 11. Thereafter, the condensed water that has come into contact with the activated carbon as the TOC adsorbing means 14 is stored in the water storage tank 11 through the opening 17 provided in the support plate 15 of the fungus capturing means 16. Further, in the water storage tank 11, when the water level of the stored water reaches a predetermined amount, excess water is drained from the drain port 18 provided on the side surface of the water storage tank 11.
以上のように、本実施の形態においては、貯水槽の内部に配置され、水に含まれるＴＯＣを捕捉するＴＯＣ吸着手段と、前記ＴＯＣ吸着手段を備える菌類捕捉手段とを具備し、燃料電池発電装置で発生した凝縮水が、前記ＴＯＣ吸着手段と接触した後、前記貯水槽に貯える構成とすることにより、ＴＯＣ吸着手段が、燃料電池発電装置から排出される排空気等から回収した凝縮水に含まれるＴＯＣを積極的に吸着することができるため、ＴＯＣ吸着手段がＴＯＣが豊富な状態になる。そして、ＴＯＣ吸着手段に吸着された豊富なＴＯＣを栄養源にして、凝縮水中に含まれる菌類が菌類捕捉手段において積極的に捕捉されることになる。また、凝縮水の中に含まれるＴＯＣは、ＴＯＣ吸着手段で積極的に吸着されるため、ＴＯＣ吸着手段ないし菌類捕捉手段の後段に配置される貯水槽や、当該貯水槽から送水ポンプを介してイオン交換装置に至る経路において、ＴＯＣ濃度が低下するため、菌類にとっては貧栄養状態となるため、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路において、菌類の増殖を抑止できることになる。その結果、水処理経路における菌類の繁殖による閉塞が回避でき、長期に亘り安定な流量を確保できることになる。 As described above, in the present embodiment, the fuel cell power generation includes the TOC adsorption unit that is disposed inside the water tank and captures the TOC contained in the water, and the fungus capture unit including the TOC adsorption unit. After the condensed water generated in the apparatus comes into contact with the TOC adsorbing means, the TOC adsorbing means collects the condensed water collected from the exhaust air discharged from the fuel cell power generation device. Since the contained TOC can be actively adsorbed, the TOC adsorbing means becomes rich in TOC. Then, the fungi contained in the condensed water are positively captured by the fungus capturing means using the abundant TOC adsorbed by the TOC adsorbing means as a nutrient source. Moreover, since the TOC contained in the condensed water is positively adsorbed by the TOC adsorbing means, a water storage tank disposed downstream of the TOC adsorbing means or the fungus capturing means, or a water pump from the water storage tank via the water pump Since the TOC concentration decreases in the path leading to the ion exchange device, the fungus is in an eutrophic state, so that the growth of the fungus can be suppressed in the water treatment path from the water storage tank to the ion exchange device via the water pump. Become. As a result, blockage due to fungal growth in the water treatment path can be avoided, and a stable flow rate can be secured over a long period of time.
なお、本実施の形態の貯水槽１１は本発明の水タンクの例であり、本実施の形態の送水ポンプ１２は本発明の水汲み出し手段の例である。 In addition, the water storage tank 11 of this Embodiment is an example of the water tank of this invention, and the water pump 12 of this Embodiment is an example of the water pumping-out means of this invention.

(Embodiment 2)
FIG. 2 shows a configuration of a water treatment apparatus according to the second embodiment of the present invention. In FIG. 2, the same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof may be omitted.
図２に示すように、本実施の形態の水処理装置は、菌類捕捉手段２１の支持板２２の開口部を、その口径が菌類の大きさより小さい細穴２３で構成した点で、実施の形態１の水処理装置とは異なる。他の構成要素は実施の形態１と同様であるので、説明を省略する。 As shown in FIG. 2, the water treatment apparatus of the present embodiment is different from the first embodiment in that the opening of the support plate 22 of the fungus capturing means 21 is configured with a narrow hole 23 whose diameter is smaller than the size of the fungus. This is different from the one water treatment apparatus. Since other components are the same as those in the first embodiment, the description thereof is omitted.
以下に、本実施の形態の水処理装置の発明のポイントである、凝縮水の流れについて説明する。 Below, the flow of the condensed water which is the point of invention of the water treatment apparatus of this Embodiment is demonstrated.
まず、送水ポンプ１２により、貯水槽１１に貯えられた水が汲み上げられ、イオン交換装置１３に送られ、その水の中に含まれるイオン成分が除去され、冷却水槽１９に貯水される。冷却水槽１９からは、冷却水循環ポンプ１１０によって、冷却水が燃料電池発電装置１１１を循環し、燃料電池発電装置１１１を一定の温度に保つ。燃料電池発電装置１１１から排出される、排空気及び排燃料ガスは、それぞれ、空気側熱交換器１１２と燃料側熱交換器１１３に送られ、排空気及び排燃料ガスに含まれる水蒸気から水が回収され、凝縮水として、貯水槽１１の上部から菌類捕捉手段２１のＴＯＣ吸着手段１４としての活性炭の上に落下する。その後、ＴＯＣ吸着手段１４としての活性炭と接触した凝縮水は、菌類捕捉手段２１の支持板２２に設けた細穴２３を通って、貯水槽１１に貯水される。また、貯水槽１１において、貯水の水位が所定量になった場合、貯水槽１１の側面に設けた排水口１８から余剰の貯水が排水される。 First, the water stored in the water storage tank 11 is pumped up by the water pump 12, sent to the ion exchange device 13, ion components contained in the water are removed, and the water is stored in the cooling water tank 19. From the cooling water tank 19, the cooling water circulates through the fuel cell power generation device 111 by the cooling water circulation pump 110 to keep the fuel cell power generation device 111 at a constant temperature. Exhaust air and exhaust fuel gas discharged from the fuel cell power generator 111 are respectively sent to the air-side heat exchanger 112 and the fuel-side heat exchanger 113, and water is supplied from water vapor contained in the exhaust air and exhaust fuel gas. It is recovered and falls as condensed water onto the activated carbon as the TOC adsorbing means 14 of the fungus capturing means 21 from the upper part of the water storage tank 11. Thereafter, the condensed water that has come into contact with the activated carbon as the TOC adsorbing means 14 is stored in the water storage tank 11 through a narrow hole 23 provided in the support plate 22 of the fungus capturing means 21. Further, in the water storage tank 11, when the water level of the stored water reaches a predetermined amount, excess water is drained from the drain port 18 provided on the side surface of the water storage tank 11.
ここで、支持板２２に設けた細穴２３が菌類をろ過する役割を果たす。つまり、細穴２３は菌類の大きさより小さいので、菌類は細穴２３を通過することはできず、したがって、菌類捕捉手段２３に留まることになる。一方、凝縮水は細穴２３を通過して、貯水槽１１に貯えられる。 Here, the fine holes 23 provided in the support plate 22 serve to filter the fungi. That is, since the fine hole 23 is smaller than the size of the fungus, the fungus cannot pass through the fine hole 23 and therefore remains in the fungus capturing means 23. On the other hand, the condensed water passes through the narrow hole 23 and is stored in the water storage tank 11.
以上のように、本実施の形態においては、菌類が、菌類捕捉手段の開口部に設けた細穴を通過することができないため、貯水槽に菌類が進入するのを遮断でき、貯水槽から送水ポンプを介してイオン交換装置に至る水処理経路における菌類の繁殖をより効果的に抑えることができる。その結果、貯水槽から送水手段を介してイオン交換装置に至る水浄化経路において、菌類による閉塞を回避できるので、安定な流量を長期にわたり確保できる水処理装置が実現可能になる。 As described above, in this embodiment, since fungi cannot pass through the narrow hole provided in the opening of the fungus capturing means, it is possible to block fungi from entering the water tank, and to supply water from the water tank. Propagation of fungi in the water treatment path leading to the ion exchange device via the pump can be more effectively suppressed. As a result, it is possible to avoid clogging by fungi in the water purification path from the water storage tank to the ion exchange device via the water supply means, so that a water treatment device that can secure a stable flow rate over a long period of time can be realized.
なお、本実施の形態の貯水槽１１は本発明の水タンクの例であり、本実施の形態の送水ポンプ１２は本発明の水汲み出し手段の例である。 In addition, the water storage tank 11 of this Embodiment is an example of the water tank of this invention, and the water pump 12 of this Embodiment is an example of the water pumping-out means of this invention.

First, the water stored in the water storage tank 11 is pumped up by the water pump 12, sent to the ion exchange device 13, ion components contained in the water are removed, and the water is stored in the cooling water tank 19. From the cooling water tank 19, the cooling water circulates through the fuel cell power generation device 111 by the cooling water circulation pump 110 to keep the fuel cell power generation device 111 at a constant temperature. Exhaust air and exhaust fuel gas discharged from the fuel cell power generator 111 are respectively sent to the air-side heat exchanger 112 and the fuel-side heat exchanger 113, and water is supplied from water vapor contained in the exhaust air and exhaust fuel gas. It is collected and falls as condensed water onto the activated carbon as the TOC adsorbing means 14 of the fungus capturing means 31 from the upper part of the water storage tank 11. Thereafter, the condensed water that has come into contact with the activated carbon as the TOC adsorption unit 14 is stored in the water storage tank 11 through the opening 17 provided in the support plate 15 of the fungus capturing unit 31. Further, the fungi captured by the activated carbon as the TOC adsorption unit 14 are sterilized by heating by the heating unit 32. Further, in the water storage tank 11, when the water level of the stored water reaches a predetermined amount, excess water is drained from the drain port 18 provided on the side surface of the water storage tank 11.
以上のように、本実施の形態においては、ＴＯＣ吸着手段で積極的に捕捉した菌類を熱殺菌できるため、菌類捕捉手段において菌類が無制限に増殖するのを抑止できる。その結果、貯水槽から送水手段を介してイオン交換装置に至る水浄化経路において、菌類による閉塞を回避できるので、安定な流量を長期にわたり確保できる水処理装置が実現可能になる。 As described above, in the present embodiment, since the fungi actively captured by the TOC adsorbing means can be thermally sterilized, it is possible to prevent the fungi from growing unlimitedly in the fungus capturing means. As a result, it is possible to avoid clogging by fungi in the water purification path from the water storage tank to the ion exchange device via the water supply means, so that a water treatment device that can secure a stable flow rate over a long period of time can be realized.

Further, the fungi captured by the activated carbon as the TOC adsorption unit 14 are sterilized by heating by the heating unit 44. Furthermore, in the water storage tank 11, when the water level of the stored water reaches a predetermined amount, excess water is drained from the drain port 18 provided on the side surface of the water storage tank 11.

まず、送水ポンプ１２により、貯水槽１１に貯えられた水が汲み上げられ、イオン交換装置１３に送られ、その水の中に含まれるイオン成分が除去され、冷却水槽１９に貯水される。冷却水槽１９からは、冷却水循環ポンプ１１０によって、冷却水が燃料電池発電装置１１１を循環し、燃料電池発電装置１１１を一定の温度に保っている。燃料電池発電装置１１１から排出される、排空気及び排燃料ガスは、それぞれ、空気側熱交換器１１２と燃料側熱交換器１１３に送られ、排空気及び排燃料ガスに含まれる水蒸気から水が回収され、凝縮水として、貯水槽１１の上部から菌類繁殖手段１６のＴＯＣ吸着手段１４としての活性炭の上に落下する。その後、ＴＯＣ吸着手段１４としての活性炭と接触した凝縮水は、菌類捕捉手段１６の支持板１５に設けた開口部１７を通って、貯水槽１１に貯水される。また、貯水槽１１において、貯水の水位が所定量になった場合、貯水槽１１の側面に設けた排水口１８から余剰の貯水が排水される。 First, the water stored in the water storage tank 11 is pumped up by the water pump 12, sent to the ion exchange device 13, ion components contained in the water are removed, and the water is stored in the cooling water tank 19. From the cooling water tank 19, the cooling water circulates through the fuel cell power generation device 111 by the cooling water circulation pump 110 to keep the fuel cell power generation device 111 at a constant temperature. Exhaust air and exhaust fuel gas discharged from the fuel cell power generator 111 are respectively sent to the air-side heat exchanger 112 and the fuel-side heat exchanger 113, and water is supplied from water vapor contained in the exhaust air and exhaust fuel gas.

Further, in the water storage tank 11, when the water level of the stored water reaches a predetermined amount, excess water is drained from the drain port 18 provided on the side surface of the water storage tank 11.
ここで、菌類捕捉手段１６は、ガイド５１を介して、貯水槽１１に取り付けられており、定期的に菌類捕捉手段１６を貯水槽１１から離脱できる構成になっている。 Here, the fungus capturing means 16 is attached to the water storage tank 11 via a guide 51, and is configured so that the fungus capturing means 16 can be periodically removed from the water storage tank 11.
以上のように、本実施の形態においては、菌類捕捉手段がガイドを介して貯水槽から離脱できる構成とすることで、菌類捕捉手段を定期的に容易にメンテナンスすることができるため、水処理経路における菌類の繁殖による閉塞が回避でき、長期に亘り安定な流量を確保できることになる。 As described above, in the present embodiment, since the fungus trapping means can be detached from the water storage tank through the guide, the fungus trapping means can be easily maintained regularly, so that the water treatment path Occlusion due to the propagation of fungi can be avoided, and a stable flow rate can be secured over a long period of time.
