Description

流體殺菌裝置Fluid sterilization device

本發明的實施方式是有關於一種流體殺菌裝置。The embodiment of the present invention relates to a fluid sterilization device.

已知如下的流體殺菌裝置，其通過將光源的發光元件所發出的紫外線，例如朝向水、氣體等流體所流動的流路照射，來對流體進行殺菌。此種流體殺菌裝置中，存在安裝有發出紫外線的發光二極體（Light Emitting Diode，LED）來作為光源的基板的裝置。 [現有技術文獻]There is known a fluid sterilization device that sterilizes fluid by irradiating ultraviolet rays emitted from a light-emitting element of a light source, for example, toward a flow path through which fluid such as water and gas flows. In such a fluid sterilization device, there is a device in which a light emitting diode (Light Emitting Diode, LED) that emits ultraviolet rays is mounted as a substrate of a light source. [Prior Art Literature]

[專利文獻] [專利文獻1] 日本專利特開2017-051290號公報 [專利文獻2] 日本專利特開2018-069166號公報[Patent Literature] [Patent Document 1] Japanese Patent Application Publication No. 2017-051290 [Patent Document 2] Japanese Patent Application Publication No. 2018-069166

[發明所要解決的問題] 但，當對在流路中流動的流體照射LED所發出的紫外線，對流體進行殺菌的情況下，為了獲得更高的殺菌效果，理想為提高LED的輸出，提高紫外線對流體的照射效率。但是，僅通過提高對LED的供給電力，或增加LED的安裝數量，具有由發熱引起的溫度限制的LED通過隨著發光的發熱而發光效率下降，因此難以提高紫外線的照射效率。[The problem to be solved by the invention] However, when the fluid flowing in the flow path is irradiated with ultraviolet rays emitted by the LED to sterilize the fluid, in order to obtain a higher sterilization effect, it is desirable to increase the output of the LED and increase the efficiency of ultraviolet radiation to the fluid. However, only by increasing the power supply to the LEDs or increasing the number of LEDs installed, LEDs with temperature restrictions due to heat generation decrease their luminous efficiency along with the heat generated by the light, and it is therefore difficult to increase the efficiency of ultraviolet radiation.

另外，光源隨著點燈時間的經過而發光效率下降，因此流體殺菌裝置中，必須將光源等組件定期更換。然而，現有的流體殺菌裝置中，更換組件時需要繁瑣的作業。In addition, the luminous efficiency of the light source decreases as the lighting time elapses. Therefore, in the fluid sterilization device, it is necessary to periodically replace the light source and other components. However, in the conventional fluid sterilization device, cumbersome work is required when replacing components.

本發明所要解決的問題為提供一種流體殺菌裝置，其不僅能夠抑制光源的溫度上升，而且能夠容易更換組件。 [解決問題的技術手段]The problem to be solved by the present invention is to provide a fluid sterilization device that not only can suppress the temperature rise of the light source, but also can easily replace the components. [Technical means to solve the problem]

In addition, in the description of each embodiment, the same reference numerals are given to the same components, and the following description is omitted.

（第一實施方式） 圖1是表示第一實施方式的流體殺菌裝置的應用例的示意圖。圖2是表示第一實施方式的流體殺菌裝置的剖面圖。(First Embodiment) Fig. 1 is a schematic diagram showing an application example of the fluid sterilization device of the first embodiment. Fig. 2 is a cross-sectional view showing the fluid sterilization device of the first embodiment.

The orthogonal coordinate system is also shown in other drawings used in the following description.

（流體殺菌裝置的構成） 如圖1所示，第一實施方式的流體殺菌裝置1不僅與供給流體的供給箱2連結，而且與將經紫外線照射的流體回收的回收箱7連結。如圖1及圖2所示，流體殺菌裝置1的上游側經由上游側流路構件4而與供給箱2連結。在上游側流路構件4，設置有從供給箱2向流體殺菌裝置1輸送流體的泵3。另外，流體殺菌裝置1的下游側經由下游側流路構件5而與回收箱7連結。在下游側流路構件5，設置有流量調整機構6，所述流量調整機構6調整從流體殺菌裝置1向回收箱7輸送的流體的流量。(Constitution of fluid sterilization device) As shown in FIG. 1, the fluid sterilization device 1 of the first embodiment is connected not only to the supply tank 2 for supplying fluid but also to the recovery tank 7 for recovering the fluid irradiated with ultraviolet rays. As shown in FIGS. 1 and 2, the upstream side of the fluid sterilization device 1 is connected to the supply tank 2 via the upstream flow path member 4. The upstream flow path member 4 is provided with a pump 3 that transfers fluid from the supply tank 2 to the fluid sterilization device 1. In addition, the downstream side of the fluid sterilization device 1 is connected to the recovery tank 7 via the downstream flow path member 5. The downstream flow path member 5 is provided with a flow rate adjustment mechanism 6 that adjusts the flow rate of the fluid sent from the fluid sterilization device 1 to the recovery tank 7.

流體殺菌裝置1例如在飲用水供給裝置中，用於對供給箱2內的水進行殺菌處理。本實施方式中，作為流體，例如應用於自來水等液體，但也可應用於氣體。The fluid sterilization device 1 is used, for example, in a drinking water supply device to sterilize water in the supply tank 2. In this embodiment, as the fluid, for example, it is applied to a liquid such as tap water, but it can also be applied to a gas.

如圖2所示，流體殺菌裝置1包括處理部20、收納構件23、光源部40、蓋構件50、連接構件10、及流路構件30。As shown in FIG. 2, the fluid sterilization device 1 includes a processing unit 20, a storage member 23, a light source unit 40, a cover member 50, a connection member 10, and a flow path member 30.

處理部20包括：管狀構件21，在內部具有使流體流通的流路24；以及反射板22，配置於管狀構件21的外表面21a。處理部20對在流路24中流動的流體進行處理。The treatment section 20 includes a tubular member 21 having a flow path 24 for allowing fluid to circulate therein, and a reflecting plate 22 disposed on the outer surface 21 a of the tubular member 21. The processing unit 20 processes the fluid flowing in the flow path 24.

管狀構件21例如為石英管（quartz tube），使紫外線透過。管狀構件21為兩端開口的筒狀的構件。反射板22是將從光源部40向流路24內照射的紫外線反射至流路24內的反射面的一例，例如使用高亮度鋁板。管狀構件21的一端支撐、固定於連接構件10，另一端支撐、固定於流路構件30。The tubular member 21 is, for example, a quartz tube, and transmits ultraviolet rays. The tubular member 21 is a cylindrical member with open ends. The reflection plate 22 is an example of reflecting ultraviolet rays irradiated from the light source unit 40 into the flow path 24 to a reflection surface in the flow path 24, and for example, a high-brightness aluminum plate is used. One end of the tubular member 21 is supported and fixed to the connecting member 10, and the other end is supported and fixed to the flow path member 30.

此外，反射板22並不限定於高亮度鋁板，只要是以高效率來反射紫外線的構件，則可以是任意構件。另外，也可代替反射板22，而在管狀構件21的外表面21a形成反射膜。反射膜是使用例如二氧化矽膜。此外，反射膜並不限定於二氧化矽膜，也可以是鋁蒸鍍膜。另外，管狀構件21並不限定於石英管，也可以是聚四氟乙烯（polytetrafluoroethylene，PTFE）等氟樹脂。另外，反射板22也可形成於管狀構件21的內表面，來代替形成於管狀構件21的外表面21a。進而，處理部20可包含反射板22與反射膜這兩者，也可不包含反射板22或反射膜。In addition, the reflection plate 22 is not limited to a high-brightness aluminum plate, and any member may be used as long as it is a member that reflects ultraviolet rays with high efficiency. In addition, instead of the reflecting plate 22, a reflecting film may be formed on the outer surface 21a of the tubular member 21. For the reflective film, for example, a silicon dioxide film is used. In addition, the reflective film is not limited to a silicon dioxide film, and may be an aluminum vapor-deposited film. In addition, the tubular member 21 is not limited to a quartz tube, and may be a fluororesin such as polytetrafluoroethylene (PTFE). In addition, the reflecting plate 22 may be formed on the inner surface of the tubular member 21 instead of being formed on the outer surface 21a of the tubular member 21. Furthermore, the processing unit 20 may include both the reflection plate 22 and the reflection film, or may not include the reflection plate 22 or the reflection film.

收納構件23收納處理部20。收納構件23例如是利用不鏽鋼（SUS）等金屬材料，形成為將處理部20收納於內部的圓筒狀，還發揮將處理部20的外周覆蓋來加以保護的蓋構件的功能。在收納構件23的兩端部形成有凸緣（flange），且一端緊固於連接構件10，另一端緊固於流路構件30。The storage member 23 stores the processing unit 20. The accommodating member 23 is formed of a metal material such as stainless steel (SUS) into a cylindrical shape that accommodates the processing portion 20 inside, and also functions as a cover member that covers and protects the outer periphery of the processing portion 20. Flanges are formed at both ends of the storage member 23, and one end is fastened to the connection member 10, and the other end is fastened to the flow path member 30.

光源部40對處理部20的流路24照射紫外線。另外，光源部40包括光源42、基板43、及支撐構件41。The light source unit 40 irradiates the flow path 24 of the processing unit 20 with ultraviolet rays. In addition, the light source unit 40 includes a light source 42, a substrate 43, and a supporting member 41.

光源42是發出紫外線的發光元件，安裝於基板43上。光源42例如為LED。光源42是由未圖示的電源來供給電力而發光。光源42是與處理部20相向而配置，對處理部20照射紫外線。另外，作為光源42，考慮到壽命及輸出，優選為在波長280[nm]附近具有峰值波長的光源，只要是例如260[nm]～280[nm]的起到殺菌作用的波長範圍即可，並不限定於紫外線的波長。即，光源42並不限定於LED，也可以是雷射二極體（laser diode，LD）等發出既定的波長範圍的紫外線的其他半導體元件。The light source 42 is a light emitting element that emits ultraviolet rays, and is mounted on the substrate 43. The light source 42 is, for example, an LED. The light source 42 emits light by being supplied with electric power from a power source not shown. The light source 42 is arranged to face the processing unit 20 and irradiates the processing unit 20 with ultraviolet rays. In addition, the light source 42 is preferably a light source having a peak wavelength near the wavelength of 280 [nm] in consideration of lifetime and output, as long as it has a sterilization wavelength range of, for example, 260 [nm] to 280 [nm]. It is not limited to the wavelength of ultraviolet rays. That is, the light source 42 is not limited to an LED, and may be another semiconductor element such as a laser diode (LD) that emits ultraviolet rays in a predetermined wavelength range.

基板43是以金屬材料作為母材來形成。在基板43上，雖未圖示，但經由絕緣層而形成有所需的導電圖案（佈線圖案），且在導電圖案上設置有光源42。此外，基板43的母材並不限定於金屬材料，例如也可以使用氧化鋁等陶瓷。基板43是固定於支撐構件41而受到支撐。The substrate 43 is formed using a metal material as a base material. On the substrate 43, although not shown, a desired conductive pattern (wiring pattern) is formed via an insulating layer, and a light source 42 is provided on the conductive pattern. In addition, the base material of the substrate 43 is not limited to a metal material, and for example, ceramics such as alumina may be used. The substrate 43 is fixed to and supported by the supporting member 41.

支撐構件41通過將安裝有光源42的基板43固定於既定的位置，來支撐光源42。此處，光源42由於隨著點燈時間的經過而發光效率下降，故而必須定期更換。因此，流體殺菌裝置1為了容易更換光源部40，而將支撐光源42的支撐構件41構成為能夠容易拆裝。這方面的詳情如後述。The supporting member 41 supports the light source 42 by fixing the substrate 43 on which the light source 42 is mounted in a predetermined position. Here, since the light-emitting efficiency of the light source 42 decreases with the passage of the lighting time, it must be replaced periodically. Therefore, in the fluid sterilization device 1, in order to easily replace the light source unit 40, the support member 41 supporting the light source 42 is configured to be easily detachable. The details of this will be described later.

蓋構件50例如是由石英玻璃（quartz glass）所形成的紫外線透過構件，配置於光源部40的前表面即Z軸負方向側。蓋構件50固定於流路構件30，在與光源部40的支撐構件41之間所包圍的空間的內部被氣密地封閉，保護光源42不受流體影響。蓋構件50使光源42所發出的紫外線透過，對在處理部20的流路24內流動的流體照射紫外線。The cover member 50 is, for example, an ultraviolet light transmitting member formed of quartz glass, and is arranged on the front surface of the light source unit 40, that is, on the negative Z-axis side. The cover member 50 is fixed to the flow path member 30, and the inside of the space enclosed with the support member 41 of the light source part 40 is hermetically sealed, and the light source 42 is protected from the fluid. The cover member 50 transmits the ultraviolet rays emitted from the light source 42 and irradiates the fluid flowing in the flow path 24 of the processing unit 20 with ultraviolet rays.

在蓋構件50的前表面，形成作為連接流路的流路39，所述流路39在與後述第一凸緣301之間將流路24與後述流路33連接。此外，蓋構件50只要是對深紫外區域的光具有透過性，且劣化少，則並無特別限定，例如可以是具有紫外線透過性的氟樹脂。另外，蓋構件50可在流路24側的表面形成預防流體中包含的微量成分的附著的防汙膜，也可為了提高來自光源42的光的透過率而在光源部40側的表面設置抗反射膜。On the front surface of the cover member 50, a flow path 39 is formed as a connecting flow path, and the flow path 39 connects the flow path 24 and the flow path 33 described later between the flow path 39 and the first flange 301 described later. In addition, the cover member 50 is not particularly limited as long as it is transparent to light in the deep ultraviolet region and has little degradation. For example, it may be a fluororesin having ultraviolet light permeability. In addition, the cover member 50 may form an antifouling film on the surface on the side of the flow path 24 to prevent the adhesion of trace components contained in the fluid, and may also provide an antifouling film on the surface on the side of the light source unit 40 in order to increase the transmittance of light from the light source 42 Reflective film.

連接構件10形成為圓筒狀，將上游側流路構件4與處理部20的流路24連結。連接構件10是經由例如未圖示的O型環來支撐管狀構件21的一端部。在連接構件10的外周部，固定著收納構件23的一端部。此外，在上游側流路構件4與處理部20的流路24之間，也可設置整流板11，所述整流板11使從上游側流路構件4流入的流體的流動整齊。The connecting member 10 is formed in a cylindrical shape, and connects the upstream flow path member 4 and the flow path 24 of the treatment section 20. The connecting member 10 supports one end of the tubular member 21 via, for example, an O-ring (not shown). To the outer periphery of the connecting member 10, one end of the storage member 23 is fixed. In addition, between the upstream flow path member 4 and the flow path 24 of the processing unit 20, a flow straightening plate 11 may be provided to make the flow of the fluid flowing in from the upstream flow path member 4 uniform.

流路構件30是將第一凸緣301與第二凸緣302，經由未圖示的緊固構件來緊固為一體而構成。第一凸緣301配置於處理部20側，第二凸緣302配置在與處理部20相反的一側。The flow path member 30 is configured by integrally fastening the first flange 301 and the second flange 302 via a fastening member not shown. The first flange 301 is arranged on the side of the treatment part 20, and the second flange 302 is arranged on the side opposite to the treatment part 20.

在流路構件30，形成流體流路，所述流體流路使處理部20的流路24與外部的下游側流路構件5連通。此處，使用圖2～圖5，對流路構件30所具有的流體流路的一例進行說明。In the flow path member 30, a fluid flow path is formed which connects the flow path 24 of the processing unit 20 with the downstream side flow path member 5 outside. Here, an example of the fluid flow path included in the flow path member 30 will be described using FIGS. 2 to 5.

圖3是圖2的A-A剖面圖。圖4是圖2的B-B剖面圖。圖5是圖2的C-C剖面圖。Fig. 3 is a sectional view taken along the line A-A in Fig. 2. Fig. 4 is a B-B sectional view of Fig. 2. Fig. 5 is a cross-sectional view taken along line C-C in Fig. 2.

如圖2、圖3所示，第二凸緣302從Z軸方向看為圓形狀，在其中央部分具有在Z軸方向貫通的貫通口35。貫通口35中，在前表面側、即Z軸負方向側，保持、固定有蓋構件50。即，貫通口35是將蓋構件50加以保持的保持部的一例。另外，在位於蓋構件50的背面側、即Z軸正方向側的貫通口35，以能拆裝的方式裝配有光源部40。As shown in FIGS. 2 and 3, the second flange 302 has a circular shape when viewed from the Z-axis direction, and has a through hole 35 penetrating in the Z-axis direction at the center portion. In the through opening 35, the cover member 50 is held and fixed on the front surface side, that is, on the Z-axis negative direction side. That is, the through opening 35 is an example of a holding portion that holds the cover member 50. In addition, the light source unit 40 is detachably attached to the through opening 35 located on the back side of the cover member 50, that is, on the positive direction side of the Z axis.

另外，如圖3、圖5所示，在第二凸緣302形成有：流路33，環狀地包圍貫通口35的周圍且在Z軸方向延伸；以及流路34，從裝配光源部40的貫通口35的側方起在徑向（此處為Y軸方向）延伸。在流路34，連接有下游側流路構件5，流路33經由流路34而與流體殺菌裝置1的外部連通。In addition, as shown in FIGS. 3 and 5, the second flange 302 is formed with a flow path 33 that surrounds the through hole 35 in a ring shape and extends in the Z-axis direction; and a flow path 34 that extends from the light source unit 40 The side of the through opening 35 extends in the radial direction (here, the Y-axis direction). The downstream flow path member 5 is connected to the flow path 34, and the flow path 33 communicates with the outside of the fluid sterilization device 1 via the flow path 34.

另一方面，如圖2、圖4所示，第一凸緣301從Z軸方向看為圓形狀，且在其中央部分包括：流路31，在Z軸方向貫通，使流路39與處理部20的流路24連通；以及多個流路32，從流路31朝向第一凸緣301的外周側而以放射狀延伸。On the other hand, as shown in FIGS. 2 and 4, the first flange 301 has a circular shape when viewed from the Z-axis direction, and includes a flow path 31 in the center portion thereof, which penetrates in the Z-axis direction, so that the flow path 39 and the treatment The flow path 24 of the portion 20 is in communication; and a plurality of flow paths 32 extend radially from the flow path 31 toward the outer peripheral side of the first flange 301.

流路構件30通過將第一凸緣301及第二凸緣302緊固，而將圖4所示的各流路32的以放射狀延伸的前端部分、與位置對應的圖3所示的流路33分別連通。由此，從上游側流路構件4供給至實施方式的流體殺菌裝置1的內部的流體是經由整流板11→流路24→流路31→流路39→流路32→流路33→流路34，而流出至下游側流路構件5的流路。流入至流路構件30的流體當通過流路33時，奪取裝配於貫通口35的光源部40所發出的熱，並且向下游側流路構件5流出。The flow path member 30 fastens the first flange 301 and the second flange 302, so that the radially extending tip portion of each flow path 32 shown in FIG. 4, and the flow shown in FIG. 3 corresponding to the position The paths 33 are connected respectively. Thus, the fluid supplied from the upstream flow path member 4 to the inside of the fluid sterilization device 1 of the embodiment passes through the flow straightening plate 11 → flow path 24 → flow path 31 → flow path 39 → flow path 32 → flow path 33 → flow Path 34, and flow out to the flow path of the downstream flow path member 5. When the fluid that has flowed into the flow path member 30 passes through the flow path 33, the heat emitted by the light source unit 40 attached to the through port 35 is taken away, and flows out to the downstream flow path member 5.

即，在流路24中，通過照射光源42所發出的紫外線而經殺菌的流體是通過管狀構件21的流路24，流向光源42的發光面側，經由貫通第一凸緣301的流路31而流入至沿著光源42的發光面的流路39，經蓋構件50折返而在流路構件30內通過流路32、流路33，從而向光源部40的側方流出。由此，包括光源42的光源部40不使用其他冷卻單元，而是使用在位於裝配於貫通口35的光源部40的側方的流路33中通過的流體，來間接但有效率地冷卻。另外，通過不使用其他冷卻單元，而使用通過流路33的流體來進行光源42的冷卻，例如能夠在不使用散熱片（radiating fin）等其他冷卻構件的情況下，抑制流體殺菌裝置1的溫度上升。That is, in the flow path 24, the fluid sterilized by irradiating ultraviolet rays from the light source 42 passes through the flow path 24 of the tubular member 21, flows to the light emitting surface side of the light source 42, and passes through the flow path 31 penetrating the first flange 301. On the other hand, the flow path 39 flowing along the light emitting surface of the light source 42 is turned back by the cover member 50, passes through the flow path 32 and the flow path 33 in the flow path member 30, and flows out to the side of the light source unit 40. Therefore, the light source unit 40 including the light source 42 does not use another cooling unit, but uses the fluid passing through the flow path 33 located on the side of the light source unit 40 mounted on the through opening 35 to cool indirectly but efficiently. In addition, by not using other cooling units, but using the fluid passing through the flow path 33 to cool the light source 42, for example, it is possible to suppress the temperature of the fluid sterilization device 1 without using other cooling members such as radiating fins. rise.

此外，流路構件30能夠包含例如SUS。另外，也可代替SUS，而由導熱率良好的銅或鋁來構成流路構件30。此外，所述實施方式中，流路構件30包括第一凸緣301及第二凸緣302，可包括三個以上的構件，另外，也可包括一個構件。In addition, the flow path member 30 can contain, for example, SUS. In addition, instead of SUS, the flow path member 30 may be composed of copper or aluminum having good thermal conductivity. In addition, in the embodiment, the flow path member 30 includes a first flange 301 and a second flange 302, which may include more than three members, and may also include one member.

另外，裝配於貫通口35且支撐光源42的支撐構件41優選為由例如銅或SUS等具有既定以上的導熱率的導熱構件來設置。光源42發出的熱經由支撐構件41而傳遞至在流路構件30內流動的流體，能夠利用流體，將光源42更有效率地冷卻。In addition, the support member 41 that is attached to the through opening 35 and supports the light source 42 is preferably provided with a thermally conductive member having a thermal conductivity higher than a predetermined value, such as copper or SUS. The heat emitted by the light source 42 is transferred to the fluid flowing in the flow path member 30 via the support member 41, and the fluid can be used to cool the light source 42 more efficiently.

此外，安裝於基板43上的光源42的個數並不限定於圖3所示的個數或大小，也可視需要來變更。另外，流路32的個數並不限定於圖4所示的個數，也可視需要來變更。進而，流路33的形狀並不限定於圖3所示的環狀，例如也可與圖4所示的流路32對應，沿著同心圓狀而隔開間隔來設置多個。In addition, the number of light sources 42 mounted on the substrate 43 is not limited to the number or size shown in FIG. 3, and can be changed as needed. In addition, the number of channels 32 is not limited to the number shown in FIG. 4, and can be changed as needed. Furthermore, the shape of the flow path 33 is not limited to the ring shape shown in FIG. 3, and for example, it may correspond to the flow path 32 shown in FIG. 4, and may be provided in plurality at intervals along a concentric circle.

（光源部的拆裝） 其次，對裝配於流路構件30的光源部40的拆裝進行說明。圖6是表示第一實施方式的裝配部的示意圖。圖7是表示第一實施方式的光源部的裝配方式的剖面示意圖。此外，圖6、圖7及後述的圖8～圖10中，將形成於流路構件30的各流路的圖示省略。(Disassembly and assembly of the light source unit) Next, the attachment and detachment of the light source unit 40 attached to the flow path member 30 will be described. Fig. 6 is a schematic diagram showing the mounting part of the first embodiment. Fig. 7 is a schematic cross-sectional view showing an assembly method of the light source unit of the first embodiment. In addition, in FIGS. 6 and 7 and FIGS. 8 to 10 described later, the illustration of each flow path formed in the flow path member 30 is omitted.

如圖6所示，裝配部36是在流路構件30的貫通口35（例如參照圖2）形成的母螺紋。另外，在構成光源部40的支撐構件41的外周面，形成與裝配部36螺合的公螺紋45。即，光源部40與流路構件30是通過裝配部36、與公螺紋45螺合而緊固固定。As shown in FIG. 6, the mounting portion 36 is a female screw formed in the through opening 35 (for example, refer to FIG. 2) of the flow path member 30. In addition, on the outer peripheral surface of the supporting member 41 constituting the light source unit 40, a male screw 45 is formed to be screwed with the mounting portion 36. That is, the light source unit 40 and the flow path member 30 are fastened and fixed by screwing with the male screw 45 through the mounting portion 36.

圖7所示的例子中，支撐構件41的內部為了輕量化而成為中空，但考慮到散熱性，支撐構件41也可形成為實心。In the example shown in FIG. 7, the inside of the support member 41 is hollow for weight reduction, but in consideration of heat dissipation, the support member 41 may be formed to be solid.

此外，例如也可在光源部40與流路構件30之間，以夾持橡膠襯墊（rubber packing）等密封構件的狀態來裝配光源部40。由此，能夠抑制流體洩漏至光源部40。In addition, for example, the light source unit 40 may be assembled between the light source unit 40 and the flow path member 30 in a state where a sealing member such as rubber packing is sandwiched. As a result, leakage of fluid to the light source unit 40 can be suppressed.

（第二實施方式） 其次，使用圖8，對第二實施方式的流體殺菌裝置1A進行說明。圖8是表示第二實施方式的裝配部的剖面示意圖。(Second Embodiment) Next, using FIG. 8, the fluid sterilization device 1A of the second embodiment will be described. Fig. 8 is a schematic cross-sectional view showing the mounting portion of the second embodiment.

第二實施方式的流體殺菌裝置1A與第一實施方式的流體殺菌裝置1相比較，光源部40及流路構件30的固定方式不同。具體而言，第二實施方式的流體殺菌裝置1A中，裝配部36a是沿著流路構件30a的貫通口35的周壁而延伸且向內側突出的鉤部。The fluid sterilization device 1A of the second embodiment is different from the fluid sterilization device 1 of the first embodiment in the way of fixing the light source unit 40 and the flow path member 30. Specifically, in the fluid sterilization device 1A of the second embodiment, the mounting portion 36a is a hook portion that extends along the peripheral wall of the through opening 35 of the flow path member 30a and protrudes inward.

另一方面，在與支撐構件41連接的裝配構件41a的外周面，設置有用以與裝配部36a卡止的鎖孔部45a。即，第二實施方式的流體殺菌裝置1A中，通過設置於光源部40a的鎖孔部45a與裝配部36a卡合，而將光源部40a固定於裝配部36a。On the other hand, the outer peripheral surface of the mounting member 41a connected to the supporting member 41 is provided with a lock hole portion 45a for locking with the mounting portion 36a. That is, in the fluid sterilization device 1A of the second embodiment, the light source portion 40a is fixed to the attachment portion 36a by the keyhole portion 45a provided in the light source portion 40a being engaged with the attachment portion 36a.

由此，依據第二實施方式的流體殺菌裝置1A，能夠在不另外使用固定件的情況下，將光源部40a與流路構件30a固定（參照圖8的右圖）。即，能夠使光源部40a及流路構件30a容易拆裝，因此能容易更換組件。Thus, according to the fluid sterilization device 1A of the second embodiment, the light source unit 40a and the flow path member 30a can be fixed without using a fixing tool separately (refer to the right figure of FIG. 8). That is, the light source unit 40a and the flow path member 30a can be easily detached and detached, so that the components can be easily replaced.

（第三實施方式） 其次，使用圖9，對第三實施方式的流體殺菌裝置1B進行說明。圖9是表示第三實施方式的裝配部的剖面示意圖。如圖9所示，第三實施方式的流體殺菌裝置1B中，鉤部45b沿著光源部40b的側壁而延伸，且向外壁側突出。(Third Embodiment) Next, using FIG. 9, the fluid sterilization device 1B of the third embodiment will be described. Fig. 9 is a schematic cross-sectional view showing a fitting part of the third embodiment. As shown in FIG. 9, in the fluid sterilization device 1B of the third embodiment, the hook portion 45b extends along the side wall of the light source portion 40b and protrudes toward the outer wall side.

而且，在流路構件30b的內壁形成與鉤部45b的卡合的裝配部36b。第三實施方式的流體殺菌裝置1B中，通過鉤部45b與設置於流路構件30b的裝配部36b卡合，而使光源部40b固定於流路構件30b。Furthermore, a fitting portion 36b that engages with the hook portion 45b is formed on the inner wall of the flow path member 30b. In the fluid sterilization device 1B of the third embodiment, the hook portion 45b is engaged with the mounting portion 36b provided on the flow path member 30b, so that the light source portion 40b is fixed to the flow path member 30b.

即便是所述情況，也能夠容易拆裝光源部40b及流路構件30b，因此容易更換組件。此外，所述第二實施方式中，也可將鎖孔部45a及裝配部36a的形狀相互調換。同樣，第三實施方式中，也可將鉤部45b及裝配部36b的形狀相互調換。即便是所述情況，也可不使用固定件，而將光源部40a、光源部40b及裝配部36a、裝配部36b固定。Even in this case, the light source unit 40b and the flow path member 30b can be easily attached and detached, and therefore the components can be easily replaced. In addition, in the second embodiment, the shapes of the keyhole portion 45a and the mounting portion 36a may be interchanged. Similarly, in the third embodiment, the shapes of the hook portion 45b and the fitting portion 36b may be interchanged. Even in the above case, the light source part 40a, the light source part 40b, the mounting part 36a, and the mounting part 36b may be fixed without using a fixing tool.

（第四實施方式） 其次，使用圖10，對第四實施方式的流體殺菌裝置1C進行說明。圖10是表示第四實施方式的裝配部的示意圖。如圖10所示，第四實施方式的流體殺菌裝置1C中，固定部45c是從光源部40c向流路構件30c突出的***部，且在***部的前端具有沿著徑向而突出的爪部46。(Fourth Embodiment) Next, using FIG. 10, the fluid sterilization apparatus 1C of 4th Embodiment is demonstrated. Fig. 10 is a schematic diagram showing a fitting part of the fourth embodiment. As shown in FIG. 10, in the fluid sterilization device 1C of the fourth embodiment, the fixing portion 45c is an insertion portion protruding from the light source portion 40c toward the flow path member 30c, and has a claw protruding in the radial direction at the tip of the insertion portion部46.

另一方面，流路構件30c在端面具有裝配部36c，所述裝配部36c是作為供固定部45c***的***孔。例如，所述裝配部36c具有卡合部17，所述卡合部17在以***有固定部45c的狀態而向既定的方向旋轉的情況下，與爪部46卡合。On the other hand, the flow path member 30c has a fitting portion 36c at the end surface as an insertion hole into which the fixing portion 45c is inserted. For example, the attachment portion 36c has an engaging portion 17 that engages with the claw portion 46 when rotating in a predetermined direction with the fixed portion 45c inserted.

圖10所示的例子中，若在已將固定部45c***裝配部36c的狀態下，使固定部45c順時針旋轉，則爪部46與卡合部17卡合。由此，能夠將光源部40c固定於流路構件30c。In the example shown in FIG. 10, if the fixing portion 45c is rotated clockwise in a state where the fixing portion 45c is inserted into the mounting portion 36c, the claw portion 46 engages with the engaging portion 17. Thereby, the light source part 40c can be fixed to the flow path member 30c.

如上所述，第四實施方式的流體殺菌裝置1C中，也能在不使用固定件的情況下，將光源部40c與流路構件30c固定，因此能夠容易更換組件。As described above, in the fluid sterilization device 1C of the fourth embodiment, the light source unit 40c and the flow path member 30c can be fixed without using a fixing tool, so that the components can be easily replaced.

此外，圖6～圖10所示的裝配部為一例，並不受其限定。即，若裝配部是使光源部與流路構件卡合而固定的結構，則也可以是其他的固定方式。通過裝配部是使光源部與流路構件卡合而固定的結構，則除了光源部以能拆裝的方式固定於流路構件以外，不僅能夠將光源部容易地裝配於流路構件，而且當在與流路構件的延伸方向垂直的剖面上看時，能夠使設置於光源部的光源42裝配於流路構件的大致中央，因此容易適當進行光源42的定位，能夠抑制由於光源部的更換而引起的殺菌性能下降。In addition, the mounting part shown in FIGS. 6-10 is an example, and is not limited to this. That is, if the mounting part is a structure in which the light source part and the flow path member are engaged and fixed, another fixing method may be used. The assembly part is a structure in which the light source part and the flow path member are engaged and fixed. In addition to the light source part being detachably fixed to the flow path member, not only the light source part can be easily assembled to the flow path member, but also When viewed in a cross section perpendicular to the direction in which the flow path member extends, the light source 42 provided in the light source section can be fitted to the approximate center of the flow path member. Therefore, it is easy to appropriately position the light source 42 and prevent the replacement of the light source section. The bactericidal performance is reduced.

（第五實施方式） 其次，使用圖11～圖14，對第五實施方式的流體殺菌裝置1D進行說明。圖11是表示第五實施方式的流體殺菌裝置的剖面圖。圖12是圖11的D-D剖面圖。圖13是圖11的E-E剖面圖。圖14是圖11的F-F剖面圖。(Fifth Embodiment) Next, the fluid sterilization device 1D of the fifth embodiment will be described using FIGS. 11 to 14. Fig. 11 is a cross-sectional view showing a fluid sterilization device of a fifth embodiment. Fig. 12 is a cross-sectional view taken along the line D-D in Fig. 11. Fig. 13 is an E-E cross-sectional view of Fig. 11. Fig. 14 is a cross-sectional view taken along the line F-F in Fig. 11.

第一實施方式的流體殺菌裝置1中，光源部40是構成為在沿著構成處理部20的管狀構件21的長度方向的Z軸方向上能夠拆裝，與此相對，第五實施方式的流體殺菌裝置1D中，不同之處在於，光源部40在與管狀構件21的長度方向交叉的徑向、此處為X軸方向上能夠拆裝。In the fluid sterilization device 1 of the first embodiment, the light source unit 40 is configured to be detachable in the Z-axis direction along the longitudinal direction of the tubular member 21 constituting the treatment unit 20. In contrast, the fluid of the fifth embodiment In the sterilization device 1D, the difference is that the light source unit 40 is detachable in the X-axis direction in the radial direction intersecting the longitudinal direction of the tubular member 21.

具體而言，如圖12、圖13所示，構成流路構件30的第二凸緣302具有貫通孔38，所述貫通孔38在X軸方向貫通，能進行光源部40的拆裝。另外，第二凸緣302中，在Y軸方向上夾持光源部40而相向延伸的流路33a是以避開貫通孔38的方式形成。Specifically, as shown in FIGS. 12 and 13, the second flange 302 constituting the flow path member 30 has a through hole 38 penetrating in the X-axis direction, and the light source unit 40 can be detached and detached. In addition, in the second flange 302, the flow path 33 a that extends oppositely while sandwiching the light source unit 40 in the Y-axis direction is formed so as to avoid the through hole 38.

另外，如圖14所示，流路33a在光源部40的背面側與下游側流路構件5連通。利用此種流體殺菌裝置1D，也能夠使用在流路33a中通過的流體來進行光源42的冷卻，由此在不使用例如散熱片等其他冷卻構件的情況下，抑制流體殺菌裝置1的溫度上升。In addition, as shown in FIG. 14, the flow path 33 a communicates with the downstream flow path member 5 on the back side of the light source unit 40. With this kind of fluid sterilization device 1D, the fluid passing through the flow path 33a can also be used to cool the light source 42, thereby suppressing the temperature rise of the fluid sterilization device 1 without using other cooling members such as heat sinks. .

此外，第五實施方式的流體殺菌裝置1D是圖示為大致稜柱狀，但並不限定於此，也可為例如圓柱狀。In addition, the fluid sterilization device 1D of the fifth embodiment is shown as a substantially prismatic shape, but it is not limited to this, and may be, for example, a cylindrical shape.

（第六實施方式） 其次，使用圖15，對第六實施方式的流體殺菌裝置1E進行說明。圖15是表示第六實施方式的流體殺菌裝置的剖面圖。(Sixth Embodiment) Next, using FIG. 15, the fluid sterilization device 1E of the sixth embodiment will be described. Fig. 15 is a cross-sectional view showing a fluid sterilization device of a sixth embodiment.

如圖15所示，第六實施方式的流體殺菌裝置1E在支撐構件41的內部形成介質流路412，且在支撐構件41的背面414側形成與介質流路412相連的開口411、開口413。另外，在開口411、開口413，連接有與冷卻裝置60相連的未圖示配管。As shown in FIG. 15, in the fluid sterilization device 1E of the sixth embodiment, a medium flow path 412 is formed inside the support member 41, and openings 411 and 413 connected to the medium flow path 412 are formed on the back surface 414 side of the support member 41. In addition, to the opening 411 and the opening 413, piping not shown connected to the cooling device 60 is connected.

此處，冷卻裝置60例如為冷卻器（chiller）。冷卻裝置60在與介質流路412之間使加熱介質流通。加熱介質例如為與處理流體不同的自來水。具體而言，從冷卻裝置60供給至開口411的冷卻介質是隨著在介質流路412中通過而在與支撐構件41之間進行熱交換，且從開口413排出。由此，能夠進一步抑制經由支撐構件41的光源42的溫度上升。Here, the cooling device 60 is, for example, a chiller. The cooling device 60 circulates the heating medium between the cooling device 60 and the medium flow path 412. The heating medium is, for example, tap water different from the treatment fluid. Specifically, the cooling medium supplied from the cooling device 60 to the opening 411 exchanges heat with the supporting member 41 as it passes through the medium flow path 412 and is discharged from the opening 413. Thereby, the temperature rise of the light source 42 passing through the support member 41 can be further suppressed.

此外，例如也可代替介質流路412而設置貫通孔，所述貫通孔從支撐構件41的背面414朝向前表面415而貫通。在所述情況下，若使作為加熱介質的例如乾燥空氣，從支撐構件41的貫通孔流通至支撐構件41的前表面415側的空間49，則例如能夠防止或消除蓋構件50的結露，抑制殺菌性能的下降。In addition, for example, instead of the medium flow path 412, a through hole may be provided that penetrates from the back surface 414 of the support member 41 toward the front surface 415. In this case, if dry air, for example, as a heating medium, flows from the through hole of the support member 41 to the space 49 on the front surface 415 side of the support member 41, for example, it is possible to prevent or eliminate condensation of the cover member 50 and suppress Decrease in sterilization performance.

如上所述，實施方式的流體殺菌裝置1包括處理部20、光源部40、蓋構件50、及流路構件30。處理部20對流體進行處理。光源部40包括朝向處理部20照射紫外線的光源42、以及支撐光源42的支撐構件41。蓋構件50配置於光源部40的前表面側，保護光源42不受流體影響。流路構件30包括將蓋構件50加以保持的保持部、以及使處理部20與外部連通的流體流路。流體流路的至少一部分位於光源部40的側方，且光源部40與流路構件30熱性接觸。流路構件30包括能拆裝地裝配光源部40的裝配部。因此，不僅能夠抑制光源42的溫度上升，而且能夠容易更換光源部40。As described above, the fluid sterilization device 1 of the embodiment includes the processing section 20, the light source section 40, the cover member 50, and the flow path member 30. The processing part 20 processes the fluid. The light source unit 40 includes a light source 42 that irradiates ultraviolet rays toward the treatment unit 20 and a support member 41 that supports the light source 42. The cover member 50 is arranged on the front surface side of the light source unit 40 and protects the light source 42 from fluid. The flow path member 30 includes a holding portion that holds the cover member 50 and a fluid flow path that communicates the processing portion 20 with the outside.
