Description

この発明は、電解生成物混合装置、バラスト水処理装置、船舶、吸引混合装置および電解生成物混合方法に関する。   The present invention relates to an electrolytic product mixing device, a ballast water treatment device, a ship, a suction mixing device, and an electrolytic product mixing method.

希釈する原水を駆動流体として電解槽から電解生成物を吸引するとともに電解生成物と希釈する原水とを混合して電解水を生成する電解水製造装置(例えば、特許文献1,2参照)がある。
また、以前より、船舶に搭載されたバラスト水に含まれる生物が遠隔地で排出されたときにその地域の生態系を破壊することが危惧されていた。このため、船舶に搭載されるバラスト水を処理する技術が求められており、現在まで、フィルタと紫外線による殺菌を組み合わせたもの、熱やキャビテーションなど物理的破砕によるもの、塩素系の薬液を注入して殺菌するもの等が発案されているが、電気分解によって塩素を発生させて殺菌するもの、も提案されている。
There is an electrolyzed water production apparatus (for example, refer to Patent Documents 1 and 2) that generates electrolyzed water by sucking an electrolyzed product from an electrolytic cell using raw water to be diluted as a driving fluid and mixing the electrolyzed product and the raw water to be diluted. .
In addition, there has been a concern over the destruction of local ecosystems when organisms contained in ballast water onboard ships are discharged from remote locations. For this reason, technology for treating ballast water mounted on ships is required, and to date, a combination of filters and sterilization with ultraviolet rays, physical crushing such as heat and cavitation, and chlorinated chemicals have been injected. Some have been proposed to sterilize, and others have been proposed that generate chlorine by electrolysis to sterilize.

しかし、上記の電解水製造装置では、電解槽が生成した電解生成物の混合対象である希釈する原水の流量を変更することが容易ではなく、例えば、既存設備の希釈する原水の流量を変更する場合には大幅な設備改修が必要となってしまう。このような課題は、電解槽が生成した電解生成物を原水に混合する混合処理装置において生じ得る共通の課題である。ここで、混合処理装置は、電解水製造装置の他に、例えば、電解槽が生成した電解生成物を混合対象の水に混合して水を殺菌または消臭する処理装置がある。この処理装置は、例えば、上水、下水、排水、バラスト水を殺菌または消臭する処理装置である。   However, in the electrolyzed water production apparatus described above, it is not easy to change the flow rate of the raw water to be diluted which is the mixing target of the electrolysis product generated by the electrolyzer. For example, the flow rate of the raw water to be diluted in the existing equipment is changed. In some cases, significant equipment upgrades are required. Such a problem is a common problem that may occur in a mixing treatment apparatus that mixes an electrolytic product generated by an electrolytic cell with raw water. Here, in addition to the electrolyzed water production apparatus, for example, there is a treatment apparatus that sterilizes or deodorizes water by mixing an electrolysis product generated by an electrolytic cell with water to be mixed. This processing apparatus is, for example, a processing apparatus that sterilizes or deodorizes clean water, sewage, drainage, and ballast water.

本発明は、上記課題に鑑みてなされたものであり、電解槽が生成した電解生成物の混合対象である原水の流量を容易に変更することが可能となる電解生成物混合装置、バラスト水処理装置、船舶、吸引混合装置および電解生成物混合方法を提供する。   The present invention has been made in view of the above problems, and an electrolytic product mixing apparatus and a ballast water treatment capable of easily changing the flow rate of raw water that is an object to be mixed with the electrolytic product generated by the electrolytic cell.

An electrolytic product mixing device comprising: a suction mixing device, wherein the suction mixing device includes a straight tube portion having a proximal tube portion and a distal tube portion, and the proximal tube portion of the straight tube portion. A cross tube portion that intersects with the tip tube portion, a cheese tube through which raw water flows from the cross tube portion toward the tip tube portion, and detachably provided on the base tube portion, Forming a gap for flowing raw water between the straight pipe section and an introduction nozzle formed with an inner hole for introducing the electrolytic product into the straight pipe section, the gap between the straight pipe section Plural types of introduction nozzles capable of changing at least one of length and cross-sectional area It includes and provides a possible connecting the inlet nozzle, having a detachable connecting portion for connecting one of these introduction nozzle into the proximal tube portion.

この構成によれば、チーズ管の基端管部に対し着脱自在な複数種類の導入ノズルを、択一的に基端管部に取り付けることで、導入ノズルと直管部との間の間隙の長さおよび断面積のうちの少なくともいずれか一方を変更することができる。よって、チーズ管を交差管部から先端管部に向けて流れて導入ノズルの内孔から電解生成物を吸引して混合させる原水が、導入ノズルと直管部との間の間隙を通って流れる際の流量を変更することができる。したがって、原水の流量を容易に変更することが可能となる。   According to this configuration, a plurality of types of introduction nozzles that are detachable with respect to the base end pipe portion of the cheese pipe are selectively attached to the base end pipe portion, so that the gap between the introduction nozzle and the straight pipe portion is reduced. At least one of the length and the cross-sectional area can be changed. Therefore, the raw water that causes the cheese tube to flow from the cross tube portion toward the tip tube portion and sucks and mixes the electrolytic product from the inner hole of the introduction nozzle flows through the gap between the introduction nozzle and the straight tube portion. The flow rate at the time can be changed. Therefore, the flow rate of raw water can be easily changed.

前記導入ノズルの内孔の先端部が、先端に向けて拡径するテーパ形状に形成されていても良い。このように構成すれば、電解生成物を効率良く吸引することができる。   The front end portion of the inner hole of the introduction nozzle may be formed in a tapered shape whose diameter increases toward the front end. If comprised in this way, an electrolysis product can be attracted | sucked efficiently.

前記導入ノズルに、前記内孔に繋がる電解生成物の導入口が複数形成されていても良い。このように構成すれば、電解槽の接続数を増減させて電解生成物の供給量を増減させることができる。   A plurality of electrolytic product introduction ports connected to the inner hole may be formed in the introduction nozzle. If comprised in this way, the supply amount of an electrolysis product can be increased / decreased by increasing / decreasing the number of connections of an electrolytic cell.

If comprised in this way, when attaching an introduction nozzle to a cheese pipe, if the contact part is made to contact | abut to a base end pipe part, the insertion length of the introduction nozzle in a straight pipe part can be prescribed | regulated. Therefore, the introduction nozzle can be easily positioned with respect to the cheese tube.

原水に電解生成物を混合して電解水を生成しても良い。この場合、原水に電解生成物を混合して電解水を生成する電解水製造装置を構成することになる。   Electrolyzed product may be mixed with raw water to produce electrolyzed water. In this case, the electrolyzed water manufacturing apparatus which mixes an electrolysis product with raw | natural water and produces | generates electrolyzed water will be comprised.

In this case, the sterilization processing apparatus which sterilizes or deodorizes raw | natural water by mixing an electrolytic product with raw | natural water will be comprised.

原水が上水、下水、または排水であっても良い。一般に、これら上水、下水や排水を処理する場合においては、フィルターだけでは病原菌やウイルス、さらに悪臭などを除去することは困難である。しかしながら、電解生成物を混合することにより、この問題を解決することができる。
また、原水が船舶用のバラスト水であっても良い。この場合、バラスト水に電解生成物を混合してバラスト水を殺菌するバラスト水処理装置を構成することになる。
本発明に係る船舶用のバラスト水処理装置は、前記バラスト水としての海水を貯留するバラスト水タンクと、前記バラスト水タンクに海水を圧送するポンプと、前記ポンプにより圧送される海水の全部または一部を前記吸引混合装置の交差管部に導入し前記原水とする上記の電解生成物混合装置と、を備える。このようなバラスト水処理装置は船舶に備えると好ましい。
バラスト水の処理能力は船舶の積載能力に合わせて、毎時数百トンから数万トンのものまで幅広いラインアップが要求されるので、導入ノズルの胴部の径を変更するだけで、流量の変更が容易にできる。
The raw water may be clean water, sewage, or drainage. In general, when treating the water, sewage or waste water, it is difficult to remove pathogenic bacteria, viruses, and offensive odors only with a filter. However, this problem can be solved by mixing electrolytic products.
The raw water may be ballast water for ships. In this case, the ballast water treatment apparatus which mixes an electrolysis product with ballast water and sterilizes ballast water is constituted.
The ballast water treatment apparatus for a ship according to the present invention includes a ballast water tank that stores seawater as the ballast water, a pump that pumps seawater into the ballast water tank, and all or one of the seawater pumped by the pump. And the electrolytic product mixing device described above, which is introduced into the cross pipe portion of the suction mixing device and used as the raw water. Such a ballast water treatment device is preferably provided in a ship.
Since the ballast water treatment capacity requires a wide lineup from several hundred tons to tens of thousands of tons per hour according to the ship's loading capacity, the flow rate can be changed simply by changing the diameter of the body of the introduction nozzle. Can be easily done.

本発明に係る吸引混合装置は、電解質溶液を電気分解して電解生成物を生成する電解槽と、前記電解槽が生成した電解生成物を、導入された原水の流れで吸引し原水に混合する吸引混合装置と、を備える電解生成物混合装置の前記吸引混合装置であって、基端管部および先端管部を有する直管部と、前記直管部の前記基端管部と前記先端管部との間に交差する交差管部とを有し、前記交差管部から前記先端管部に向けて原水が流れるチーズ管と、前記基端管部に着脱自在に設けられ、前記直管部との間に原水を流動させる間隙を形成し、電解生成物を前記直管部に導入する内孔が形成された導入ノズルと、を備え、前記直管部との間の間隙の長さおよび断面積のうちの少なくともいずれか一方を変更可能な複数種類の前記導入ノズルを備えており、これら導入ノズルを連結可能であって、これら導入ノズルのうちの一つを前記基端管部に連結する着脱連結部を有する。   The suction mixing device according to the present invention sucks the electrolytic solution generated by electrolyzing the electrolytic solution and generates an electrolytic product, and the electrolytic product generated by the electrolytic bath with the flow of the introduced raw water, and mixes the raw water with the electrolytic product. A suction mixing device of an electrolytic product mixing device comprising a suction mixing device, a straight tube portion having a proximal end tube portion and a distal end tube portion, and the proximal end tube portion and the distal end tube of the straight tube portion A cross-pipe part that intersects with the part, a cheese pipe through which raw water flows from the cross-pipe part toward the tip pipe part, and a base pipe part that is detachably provided, and the straight pipe part An introduction nozzle formed with an inner hole for introducing an electrolysis product into the straight pipe part, and a gap length between the straight pipe part and Provided with a plurality of introduction nozzles capable of changing at least one of the cross-sectional areas Ri, a possible connecting the inlet nozzle, having a detachable connecting portion for connecting one of these introduction nozzle into the proximal tube portion.

この構成によれば、チーズ管の基端管部に対し着脱自在な複数種類の導入ノズルを、択一的に基端管部に取り付けることで、導入ノズルと直管部との間の間隙の長さおよび断面積のうちの少なくともいずれか一方を変更することができる。よって、チーズ管を交差管部から先端管部に向けて流れて導入ノズルの内孔から電解生成物を吸引して混合させる原水が、導入ノズルと直管部との間の間隙を通って流れる際の流量を変更することができる。したがって、原水の流量を容易に変更することが可能となる。
本発明の原理は、オリフィス流量計(差圧式流量計)と同じであり、管の途中で流れが絞られると、流体の圧力が下がる。この変化は流体密度と流速に関係するので、上流側と下流側の圧力差を測れば流量が判明する。この流量は体積流量であり、小流量から大流量まで測ることができる。市販されている一般の流量計は出荷前に流体を流し、流量対出力の関係を調べる校正作業を必要とするが、差圧式流量計については、特定の絞り構造と管口径範囲に従って製作・設置すれば実流校正が不要である。流量計等校正を必要とする計測機器に対しては、流量が大きくなると初期費用、さらにはメンテナンス等多大なコストがかかる。しかし、本発明では導入ノズルの胴部の径における寸法検査の精度で流量が保証されるので、コストの面で非常に有利である。
According to this configuration, a plurality of types of introduction nozzles that are detachable with respect to the base end pipe portion of the cheese pipe are selectively attached to the base end pipe portion, so that the gap between the introduction nozzle and the straight pipe portion is reduced. At least one of the length and the cross-sectional area can be changed. Therefore, the raw water that causes the cheese tube to flow from the cross tube portion toward the tip tube portion and sucks and mixes the electrolytic product from the inner hole of the introduction nozzle flows through the gap between the introduction nozzle and the straight tube portion. The flow rate at the time can be changed. Therefore, the flow rate of raw water can be easily changed.
The principle of the present invention is the same as that of an orifice flow meter (differential pressure flow meter), and when the flow is throttled in the middle of the pipe, the pressure of the fluid decreases. Since this change is related to fluid density and flow velocity, the flow rate can be determined by measuring the pressure difference between the upstream side and the downstream side. This flow rate is a volume flow rate and can be measured from a small flow rate to a large flow rate. Commercially available general flowmeters require fluid calibration before shipment to check the relationship between flow rate and output, but differential pressure flowmeters are manufactured and installed according to a specific throttle structure and pipe diameter range. If this is the case, actual flow calibration is unnecessary. For measuring instruments that require calibration, such as a flow meter, when the flow rate increases, initial costs and maintenance costs are high. However, in the present invention, the flow rate is guaranteed with the accuracy of the dimensional inspection at the diameter of the body portion of the introduction nozzle, which is very advantageous in terms of cost.

本発明に係る電解生成物混合方法は、電解質溶液を電気分解して電解生成物を生成する電解槽と、前記電解槽が生成した電解生成物を、導入された原水の流れで吸引し原水に混合する吸引混合装置と、を備え、前記吸引混合装置が、基端管部および先端管部を有する直管部と、前記直管部の前記基端管部と前記先端管部との間に交差する交差管部とを有し、前記交差管部から前記先端管部に向けて原水が流れるチーズ管と、前記基端管部に着脱自在に設けられ、前記直管部との間に原水を流動させる間隙を形成し、電解生成物を前記直管部に導入する内孔が形成された導入ノズルと、を備える電解生成物混合装置を用いた電解生成物混合方法であって、複数種類の前記導入ノズルを準備し、これら導入ノズルを前記基端管部に択一的に取り付けることで、前記基端管部に取り付けられた前記導入ノズルと前記直管部との間の間隙の長さおよび断面積のうちの少なくともいずれか一方を変更する。   The electrolytic product mixing method according to the present invention includes an electrolytic cell that electrolyzes an electrolytic solution to produce an electrolytic product, and an electrolytic product generated by the electrolytic cell is sucked into the raw water by the flow of the introduced raw water. A suction mixing device for mixing, wherein the suction mixing device includes a straight tube portion having a proximal tube portion and a distal tube portion, and between the proximal tube portion and the distal tube portion of the straight tube portion. A cheese tube that flows through the intersecting tube portion toward the distal end tube portion, and is detachably provided on the proximal tube portion, and between the straight tube portion and the raw water An electrolysis product mixing method using an electrolysis product mixing apparatus comprising: an introduction nozzle formed with an inner hole for forming a gap for fluidizing and introducing an electrolysis product into the straight pipe portion; The introduction nozzles are prepared, and these introduction nozzles are selectively attached to the proximal end pipe portion. In Rukoto, changes at least one of the length and cross-sectional area of the gap between said introduction nozzle attached to the proximal tube portion straight pipe section.

この構成によれば、チーズ管の基端管部に対し着脱自在な複数種類の導入ノズルを、択一的に基端管部に取り付けることで、導入ノズルと直管部との間の間隙の長さおよび断面積のうちの少なくともいずれか一方を変更する。よって、チーズ管を交差管部から先端管部に向けて流れて導入ノズルの内孔から電解生成物を吸引して混合させる原水が、導入ノズルと直管部との間の間隙を通って流れる際の流量を変更することができる。したがって、原水の流量を容易に変更することが可能となる。   According to this configuration, a plurality of types of introduction nozzles that are detachable with respect to the base end pipe portion of the cheese pipe are selectively attached to the base end pipe portion, so that the gap between the introduction nozzle and the straight pipe portion is reduced. At least one of the length and the cross-sectional area is changed. Therefore, the raw water that causes the cheese tube to flow from the cross tube portion toward the tip tube portion and sucks and mixes the electrolytic product from the inner hole of the introduction nozzle flows through the gap between the introduction nozzle and the straight tube portion.

以下、本発明に係る一実施形態の電解生成物混合装置について、図面を参照して説明する。   Hereinafter, an electrolytic product mixing apparatus according to an embodiment of the present invention will be described with reference to the drawings.

図1に示すように、実施形態の電解生成物混合装置11は、電解質溶液を貯留する電解質溶液タンク12と、電解質溶液タンク12から電解質溶液を吸引し吐出する電解質溶液ポンプ13と、電解質溶液ポンプ13から吐出された電解質溶液が導入される電解槽14と、電解槽14に電力を供給する電解電源15とを有する電気分解モジュール16を備えている。電解槽14は、電解電源15から供給された電力で電解質溶液を電気分解する。また、電解生成物混合装置11は、原水が加圧されて導入されるとともに、導入された原水の流れで、電解槽14が生成した電解生成物を吸引し原水に混合して導出する吸引混合装置21を備えている。   As shown in FIG. 1, the electrolytic product mixing device 11 of the embodiment includes an electrolyte solution tank 12 that stores an electrolyte solution, an electrolyte solution pump 13 that sucks and discharges the electrolyte solution from the electrolyte solution tank 12, and an electrolyte solution pump. An electrolysis module 16 having an electrolytic cell 14 into which the electrolyte solution discharged from 13 is introduced and an electrolytic power source 15 for supplying electric power to the electrolytic cell 14 is provided. The electrolytic cell 14 electrolyzes the electrolyte solution with electric power supplied from the electrolytic power supply 15. In addition, the electrolytic product mixing device 11 is sucked and mixed in which raw water is introduced under pressure and the electrolytic product generated by the electrolytic cell 14 is sucked and mixed with the raw water by the flow of the introduced raw water. A device 21 is provided.

電解槽14は、導入された電解質溶液を電気分解して電解生成物を生成する。ここで、例えば、電解質溶液は、塩化ナトリウム水溶液、塩酸水溶液等の塩素イオンを含有するものであり、電解槽14は、電解酸化の作用により電解生成物として塩素ガスを生成する。吸引混合装置21には、原水が導入されることになり、電解生成物である塩素ガスを、導入された原水の流れで吸引し原水に混合する。電解槽14には、公知のものを適宜用いることができる。以下、このように電解槽14が電解生成物として塩素ガスを生成する場合を例にとり説明する。   The electrolytic cell 14 electrolyzes the introduced electrolyte solution to generate an electrolytic product. Here, for example, the electrolyte solution contains chlorine ions such as an aqueous sodium chloride solution and an aqueous hydrochloric acid solution, and the electrolytic cell 14 generates chlorine gas as an electrolytic product by the action of electrolytic oxidation. Raw water is introduced into the suction mixing device 21, and chlorine gas, which is an electrolysis product, is sucked by the flow of the introduced raw water and mixed with the raw water. A well-known thing can be used for the electrolytic vessel 14 suitably. Hereinafter, the case where the electrolytic cell 14 generates chlorine gas as an electrolytic product will be described as an example.

図2に示すように、吸引混合装置21は、直線状に延びる円筒状の直管部22と、直線状に延びて直管部22の軸方向の中間位置の周壁に交差する円筒状の交差管部23とを有するT字状のチーズ管24(Tee、Tees)と、このチーズ管24に着脱自在に設けられる導入ノズル25と、チーズ管24に対し導入ノズル25を取り付けたり取り外したりするためのユニオンナット26とを有している。   As shown in FIG. 2, the suction mixing device 21 includes a cylindrical straight pipe portion 22 that extends linearly, and a cylindrical cross that extends linearly and intersects the peripheral wall at an intermediate position in the axial direction of the straight pipe portion 22. T-shaped cheese tube 24 (Tee, Tees) having a tube part 23, an introduction nozzle 25 that is detachably provided on the cheese tube 24, and for attaching or removing the introduction nozzle 25 to or from the cheese tube 24 The union nut 26 is provided.

交差管部23は、直管部22の中心軸線に垂直となっており、直管部22の周壁から径方向外方に突出する。交差管部23は、一定径の内孔31を有している。交差管部23は、直管部22とは反対側の導入口32が原水の供給元に連通させられている。つまり、チーズ管24には、交差管部23に導入口32から原水が導入されることになり、この原水の流れの方向における交差管部23の下流側に直管部22が配置されている。   The cross pipe part 23 is perpendicular to the central axis of the straight pipe part 22 and protrudes radially outward from the peripheral wall of the straight pipe part 22. The cross pipe portion 23 has an inner hole 31 having a constant diameter. As for the cross pipe part 23, the inlet 32 on the opposite side to the straight pipe part 22 is connected with the supply source of raw | natural water. That is, in the cheese pipe 24, raw water is introduced into the cross pipe part 23 from the introduction port 32, and the straight pipe part 22 is arranged on the downstream side of the cross pipe part 23 in the flow direction of the raw water. .

直管部22は、交差管部23の直管部22への開口部である内側開口部33を除き、内周面41が軸方向位置によらず一定径の円筒面となっている。つまり、直管部22は、一定径の内孔42を有している。   In the straight pipe portion 22, the inner peripheral surface 41 is a cylindrical surface having a constant diameter regardless of the axial position, except for an inner opening 33 which is an opening to the straight pipe portion 22 of the cross pipe portion 23. That is, the straight pipe portion 22 has an inner hole 42 having a constant diameter.

直管部22は、交差管部23よりも軸方向一側の部分が、導入ノズル25が接続されて閉塞される基端管部43となっており、交差管部23よりも軸方向の基端管部43とは反対側の部分が先端管部44となっている。先端管部44は、軸方向の交差管部23とは反対の先端口部45が、塩素ガス混合後の原水の供給先に接続される。つまり、原水の流れの方向における交差管部23の下流側に、先端管部44が配置されている。言い換えれば、チーズ管24においては、交差管部23が先端管部44よりも原水の流れ方向の上流側にあり、先端管部44が交差管部23よりも原水の流れ方向の下流側にある。よって、チーズ管24には、交差管部23から先端管部44に向けて原水が流れることになり、原水は塩素ガスが混合された後(後述)、先端管部44の先端口部45から供給先に向けて排出される。   In the straight pipe portion 22, a portion on one side in the axial direction with respect to the cross pipe portion 23 is a base end pipe portion 43 that is closed by being connected to the introduction nozzle 25. A portion opposite to the end tube portion 43 is a tip tube portion 44. The distal end pipe portion 44 has a distal end opening portion 45 opposite to the axially intersecting tube portion 23 connected to a supply destination of raw water after chlorine gas mixing. That is, the distal end pipe part 44 is arranged on the downstream side of the cross pipe part 23 in the direction of the raw water flow. In other words, in the cheese tube 24, the cross tube portion 23 is on the upstream side in the flow direction of the raw water with respect to the tip tube portion 44, and the tip tube portion 44 is on the downstream side in the flow direction of the raw water with respect to the cross tube portion 23. . Therefore, raw water flows into the cheese tube 24 from the cross tube portion 23 toward the distal end tube portion 44. After the chlorine water is mixed with the chlorine water (described later), the raw water flows from the distal end portion 45 of the distal end tube portion 44. It is discharged toward the supplier.

基端管部43には、端部に径方向外方に突出する円環状のフランジ部48が形成されている。ユニオンナット26は、円筒状をなしており、軸方向一端に径方向内側に突出する円環状の内フランジ部51が形成され、軸方向他側の内周側にメネジ52が形成されている。ユニオンナット26は、内フランジ部51が基端管部43のユニオンフランジとしてのフランジ部48と交差管部23との間で移動可能となるように、チーズ管24に保持されており、内フランジ部51が基端管部43のフランジ部48に当接することで、それ以上、交差管部23から離れる方向への移動が規制される。このように内フランジ部51がフランジ部48に当接すると、ユニオンナット26のメネジ52が基端管部43よりも軸方向外側に配置される。   The proximal end pipe part 43 is formed with an annular flange part 48 protruding outward in the radial direction at the end part. The union nut 26 has a cylindrical shape, and an annular inner flange portion 51 protruding radially inward is formed at one end in the axial direction, and a female screw 52 is formed on the inner peripheral side on the other side in the axial direction. The union nut 26 is held by the cheese tube 24 so that the inner flange portion 51 can move between the flange portion 48 as the union flange of the proximal end tube portion 43 and the cross tube portion 23. When the part 51 abuts on the flange part 48 of the proximal end pipe part 43, the movement in the direction away from the cross pipe part 23 is further restricted. When the inner flange portion 51 abuts on the flange portion 48 in this way, the female thread 52 of the union nut 26 is disposed on the outer side in the axial direction than the proximal end tube portion 43.

導入ノズル25は、チーズ管24の直管部22に基端管部43から挿入されて、この基端管部43に装着されている。導入ノズル25は、基端管部43に対し繰り返しの装着および繰り返しの取り外しが自在、つまり着脱自在となっている。導入ノズル25は、ユニオンナット26のメネジ52に螺合するオネジ61が軸方向一側の外周部に形成された基端のユニオンボルト62と、ユニオンボルト62の内側に嵌合されて固定される基端の円筒状のベース63と、ベース63からチーズ管24の直管部22内に向けて延出するノズル本体64と、ベース63の直管部22とは反対側に一端側が取り付けられる接続管体65とを有している。接続管体65は、他端側が図1に示す電解槽14に連通される。   The introduction nozzle 25 is inserted into the straight tube portion 22 of the cheese tube 24 from the proximal tube portion 43 and attached to the proximal tube portion 43. The introduction nozzle 25 is freely attachable and detachable repeatedly, that is, detachable from the proximal end pipe portion 43. The introduction nozzle 25 is fitted and fixed to a base end union bolt 62 formed on the outer peripheral portion on one side in the axial direction, and a base end union bolt 62 screwed into the internal thread 52 of the union nut 26. A cylindrical base 63 at the base end, a nozzle body 64 extending from the base 63 into the straight pipe portion 22 of the cheese tube 24, and a connection where one end side is attached to the opposite side of the straight pipe portion 22 of the base 63 And a tubular body 65. The other end side of the connecting pipe body 65 communicates with the electrolytic cell 14 shown in FIG.

図2に示すように、ユニオンボルト62は、円筒状をなしており、内側に、軸方向のオネジ61とは反対側の端部から中間部にかけて形成された嵌合孔71と、軸方向のオネジ61側の端部に形成された内孔72とを有している。内孔72は嵌合孔71よりも小径となっており、よって、ユニオンボルト62には軸方向のオネジ61側の端部に、径方向内方に突出する円環状の内フランジ部73が形成されている。ベース63は、ユニオンボルト62の嵌合孔71に嵌合固定されて内フランジ部73に当接しており、この状態でユニオンボルト62との隙間が密閉される。ユニオンボルト62には、軸方向のオネジ61側の端面76に、端面76から軸方向に凹む円環状の凹部77が形成されている。この凹部77にはOリング78が配置されている。   As shown in FIG. 2, the union bolt 62 has a cylindrical shape, and includes a fitting hole 71 formed on an inner side from an end portion on the opposite side to the axial male screw 61 to an intermediate portion, and an axial direction. And an inner hole 72 formed at the end on the male screw 61 side. The inner hole 72 has a smaller diameter than the fitting hole 71. Therefore, the union bolt 62 is formed with an annular inner flange portion 73 projecting radially inward at the end on the axial male screw 61 side. Has been. The base 63 is fitted and fixed in the fitting hole 71 of the union bolt 62 and is in contact with the inner flange portion 73. In this state, the gap with the union bolt 62 is sealed. The union bolt 62 is formed with an annular recess 77 that is recessed in the axial direction from the end surface 76 on the end surface 76 on the male screw 61 side in the axial direction. An O-ring 78 is disposed in the recess 77.

導入ノズル25は、ユニオンボルト62の凹部77にOリング78が配置された状態で、ノズル本体64がチーズ管24の直管部22の内孔42に基端管部43から挿入された後、ユニオンボルト62の凹部77側の端面76をチーズ管24の基端管部43のフランジ部48側の端面81に当接させる。この状態で、ユニオンボルト62のオネジ61に、ユニオンナット26のメネジ52を螺合させてユニオンナット26を締め付けることで、ユニオンナット26の内フランジ部51が基端管部43のフランジ部48をユニオンボルト62に押し付ける。その際に、ユニオンボルト62の凹部77のOリング78が、基端管部43の端面81に当接して弾性変形する。これにより、Oリング78がユニオンボルト62と基端管部43との隙間をシールする。このようにして、導入ノズル25がチーズ管24の基端管部43に取り付けられる。この状態から、ユニオンナット26のメネジ52のユニオンナット26のオネジ61への螺合が緩められて解除されると、導入ノズル25は、チーズ管24の基端管部43への連結が解除され、基端管部43から取り外される。   After the nozzle body 64 is inserted into the inner hole 42 of the straight tube portion 22 of the cheese tube 24 from the proximal tube portion 43 with the O-ring 78 disposed in the recess 77 of the union bolt 62, The end surface 76 on the concave portion 77 side of the union bolt 62 is brought into contact with the end surface 81 on the flange portion 48 side of the proximal tube portion 43 of the cheese tube 24. In this state, by screwing the female screw 52 of the union nut 26 to the male screw 61 of the union bolt 62 and tightening the union nut 26, the inner flange portion 51 of the union nut 26 moves the flange portion 48 of the proximal end pipe portion 43. Press against the union bolt 62. At that time, the O-ring 78 of the recess 77 of the union bolt 62 comes into contact with the end surface 81 of the proximal end tube portion 43 and elastically deforms. Thereby, the O-ring 78 seals the gap between the union bolt 62 and the proximal end pipe portion 43. In this way, the introduction nozzle 25 is attached to the proximal end tube portion 43 of the cheese tube 24. From this state, when the threaded engagement of the female thread 52 of the union nut 26 with the male thread 61 of the union nut 26 is loosened and released, the introduction nozzle 25 is released from the connection to the proximal end pipe portion 43 of the cheese pipe 24. The base end pipe part 43 is removed.

導入ノズル25は、その基端部となるユニオンボルト62およびベース63が、直管部22の内孔に挿入されずに直管部22の外に配されてチーズ管24にユニオンナット26によって取り付けられる取付部85となっている。また、基端管部43のフランジ部48と、ユニオンナット26と、ユニオンボルト62とが、導入ノズル25の取付部85を基端管部43に着脱自在に連結する着脱連結部86となっている。つまり、着脱連結部86はユニオンジョイント(自在ユニオン)である。ユニオンボルト62の内フランジ部73の内周面88は、チーズ管24の直管部22の内周面41と同径となっており、導入ノズル25がチーズ管24に取り付けられた状態で、直管部22の内周面41と中心軸線を一致させて連続する。   The introduction nozzle 25 has a union bolt 62 and a base 63 serving as a base end thereof arranged outside the straight pipe portion 22 without being inserted into the inner hole of the straight pipe portion 22 and attached to the cheese pipe 24 by a union nut 26. It becomes the attaching part 85 to be made. Further, the flange portion 48 of the proximal end tube portion 43, the union nut 26, and the union bolt 62 serve as an attachment / detachment connection portion 86 that removably connects the attachment portion 85 of the introduction nozzle 25 to the proximal end tube portion 43. Yes. That is, the detachable connecting portion 86 is a union joint (a universal union). The inner peripheral surface 88 of the inner flange portion 73 of the union bolt 62 has the same diameter as the inner peripheral surface 41 of the straight tube portion 22 of the cheese tube 24, and the introduction nozzle 25 is attached to the cheese tube 24. The inner peripheral surface 41 of the straight pipe part 22 and the central axis line are made to coincide with each other.

ユニオンボルト62の軸方向のオネジ61側の端部は、基端管部43の軸方向のフランジ部48側の端面81に、その端面76で当接する当接部91となっている。導入ノズル25は、そのオネジ61がユニオンナット26のメネジ52に螺合されて締め付けられると、当接部91が基端管部43の軸方向の端部に当接する。この状態で、導入ノズル25の基端部にあるユニオンボルト62の当接部91が、基端管部43に当接して直管部22内への導入ノズル25の挿入長さを規定する。言い換えれば、当接部91からノズル本体64の突出長さは既定であり、当接部91が、基端管部43に当接するとこの既定の長さのノズル本体64の先端面94が直管部22に対して軸方向に位置決めされる。導入ノズル25の挿入長さは、ノズル本体64が交差管部23の内側開口部33を直管部22の軸方向に横断し、先端管部44の先端口部45と交差管部23の内側開口部33との間に先端面94が位置する長さとなっている。   The end portion of the union bolt 62 on the male screw 61 side in the axial direction is an abutting portion 91 that abuts on the end surface 81 of the proximal tube portion 43 on the flange portion 48 side in the axial direction. When the male screw 61 of the introduction nozzle 25 is screwed into the female screw 52 of the union nut 26 and tightened, the contact portion 91 contacts the end portion of the proximal tube portion 43 in the axial direction. In this state, the abutment portion 91 of the union bolt 62 at the proximal end portion of the introduction nozzle 25 abuts on the proximal end tube portion 43 to define the insertion length of the introduction nozzle 25 into the straight tube portion 22. In other words, the protruding length of the nozzle body 64 from the abutting portion 91 is a predetermined length, and when the abutting portion 91 abuts on the proximal end tube portion 43, the distal end surface 94 of the nozzle body 64 of this predetermined length is directly straight. The tube portion 22 is positioned in the axial direction. The insertion length of the introduction nozzle 25 is such that the nozzle body 64 crosses the inner opening 33 of the cross pipe portion 23 in the axial direction of the straight pipe portion 22, and the front end portion 45 of the tip pipe portion 44 and the inner side of the cross pipe portion 23. The length is such that the front end surface 94 is located between the opening 33 and the opening 33.

導入ノズル25は、中心軸線上に内孔95を有しており、ノズル本体64はこの内孔95が軸方向に貫通する円筒状に形成されている。ノズル本体64は、その外周面96が軸方向位置によらず一定径の円筒面となっている。ノズル本体64は、取付部85がチーズ管24の基端管部43にユニオンナット26によって取り付けられた状態では、直管部22の内側に直管部22と中心軸を一致させて配置されることになる。よって、チーズ管24の直管部22は、導入ノズル25のノズル本体64を覆うように外側に配置される外筒管であり、ノズル本体64は、直管部22の内側に配置される内筒管である。   The introduction nozzle 25 has an inner hole 95 on the central axis, and the nozzle body 64 is formed in a cylindrical shape through which the inner hole 95 penetrates in the axial direction. The outer peripheral surface 96 of the nozzle body 64 is a cylindrical surface having a constant diameter regardless of the axial position. The nozzle main body 64 is arranged with the straight pipe portion 22 and the central axis aligned with each other inside the straight pipe portion 22 in a state where the attachment portion 85 is attached to the proximal end pipe portion 43 of the cheese pipe 24 by the union nut 26. It will be. Therefore, the straight tube portion 22 of the cheese tube 24 is an outer tube disposed outside so as to cover the nozzle body 64 of the introduction nozzle 25, and the nozzle body 64 is disposed inside the straight tube portion 22. It is a tube.

取付部85が基端管部43に取り付けられた状態で、直管部22の内周面41およびユニオンボルト62の内フランジ部73の内周面88と、ノズル本体64の外周面96との間には間隙101が形成される。言い換えれば、導入ノズル25は、チーズ管24の直管部22に装着された状態で直管部22およびユニオンボルト62の内フランジ部73との間に間隙101を形成する。この間隙101は、円筒状をなしており、ベース63で一端が閉塞され、他端の開口部102がノズル本体64の先端位置で、直管部22内のノズル本体64よりも先端口部45側に開口している。この間隙101は、ノズル本体64のベース63からの突出長さと同じ長さであり、交差管部23の内側開口部33を直管部22の軸方向に横断する長さとなっている。交差管部23に導入された原水は、この間隙101を流動して間隙101の開口部102から先端管部44内のノズル本体64がない範囲に至り、先端口部45から供給先に向けて流れる。   With the attachment portion 85 attached to the proximal end tube portion 43, the inner peripheral surface 41 of the straight tube portion 22, the inner peripheral surface 88 of the inner flange portion 73 of the union bolt 62, and the outer peripheral surface 96 of the nozzle body 64. A gap 101 is formed between them. In other words, the introduction nozzle 25 forms a gap 101 between the straight pipe portion 22 and the inner flange portion 73 of the union bolt 62 in a state where the introduction nozzle 25 is attached to the straight pipe portion 22 of the cheese pipe 24. The gap 101 has a cylindrical shape, one end is closed by the base 63, and the opening 102 at the other end is located at the distal end position of the nozzle main body 64, and the distal end opening 45 is more than the nozzle main body 64 in the straight pipe portion 22. Open to the side. The gap 101 has the same length as the protruding length of the nozzle body 64 from the base 63, and is a length that crosses the inner opening 33 of the intersecting pipe portion 23 in the axial direction of the straight pipe portion 22. The raw water introduced into the cross pipe portion 23 flows through the gap 101 to reach a range where there is no nozzle body 64 in the tip pipe portion 44 from the opening 102 of the gap 101, and from the tip mouth portion 45 toward the supply destination. Flowing.

導入ノズル25の内孔95は、接続管体65の内部に連通しており、よって、図1に示す電解槽14で生成された塩素ガスを流動させる。図3に示すように、導入ノズル25の内孔95は、先端部に、先端面94に向けて拡径するテーパ形状をなすテーパ孔部105を有しており、テーパ孔部105よりも基端側に、軸方向位置によらずに一定径の円筒孔部106を有している。テーパ孔部105の円筒孔部106とは反対側の端部が内孔95の開口部107となっている。   The inner hole 95 of the introduction nozzle 25 communicates with the inside of the connecting pipe body 65, and thus flows the chlorine gas generated in the electrolytic cell 14 shown in FIG. As shown in FIG. 3, the inner hole 95 of the introduction nozzle 25 has a tapered hole portion 105 having a tapered shape whose diameter increases toward the distal end surface 94 at the distal end portion. A cylindrical hole 106 having a constant diameter is provided on the end side regardless of the axial position. An end of the tapered hole 105 opposite to the cylindrical hole 106 is an opening 107 of the inner hole 95.

図2に示す吸引混合装置21は、チーズ管24の交差管部23に加圧された原水が導入されて、ノズル本体64と直管部22との間の間隙101を通過して直管部22の先端管部44に至り、供給先に向けて流れる。その際の原水の流れが、エジェクタの原理で導入ノズル25の内孔95の開口部107付近に負圧を発生させ、電解槽14から電解生成物である塩素ガスを内孔95を介して吸引する。これにより、塩素ガスが、内孔95から直管部22の内孔42内の開口部107近傍の混合部111で原水に導入されて混合される。このように塩素ガスが混合された原水が供給先に向けて流れる。つまり、吸引混合装置21は、液体である原水を駆動流体として気体である塩素ガスを吸引するエジェクタとなっている。   In the suction mixing device 21 shown in FIG. 2, pressurized raw water is introduced into the cross tube portion 23 of the cheese tube 24 and passes through the gap 101 between the nozzle body 64 and the straight tube portion 22. 22 reaches the distal end pipe portion 44 and flows toward the supply destination. The flow of raw water at that time generates a negative pressure in the vicinity of the opening 107 of the inner hole 95 of the introduction nozzle 25 by the principle of the ejector, and sucks chlorine gas as an electrolytic product from the electrolytic cell 14 through the inner hole 95. To do. Thus, chlorine gas is introduced from the inner hole 95 into the raw water and mixed in the mixing part 111 in the vicinity of the opening 107 in the inner hole 42 of the straight pipe part 22. In this way, raw water mixed with chlorine gas flows toward the supply destination. That is, the suction mixing device 21 is an ejector that sucks gaseous chlorine gas using raw water that is liquid as a driving fluid.

ここで、吸引混合装置21の原水および塩素ガスの流れに関係する部分の寸法の具体例を説明する。例えば、直管部22の内孔42の内径がφ30mmに、ノズル本体64の外径がφ29mmに、図3に示す導入ノズル25の内孔95の円筒孔部106の内径がφ4mmに、テーパ孔部105のノズル本体64の先端面94からの深さが25mmに、テーパ孔部105の角度(テーパ孔部105を中心軸線を含む平面で断面としたときに出現する2線のなす角度)が40度となっている。この場合、図2に示す直管部22とノズル本体64との間隙101は、中心軸線から径方向片側に延びる半径線上で0.5mmの寸法となる。   Here, the specific example of the dimension of the part relevant to the flow of the raw | natural water and chlorine gas of the suction mixing apparatus 21 is demonstrated. For example, the inner diameter of the inner hole 42 of the straight pipe portion 22 is φ30 mm, the outer diameter of the nozzle body 64 is φ29 mm, the inner diameter of the cylindrical hole portion 106 of the inner hole 95 of the introduction nozzle 25 shown in FIG. The depth of the portion 105 from the tip surface 94 of the nozzle body 64 is 25 mm, and the angle of the tapered hole portion 105 (the angle formed by two lines that appear when the tapered hole portion 105 is taken as a cross section in a plane including the central axis). It is 40 degrees. In this case, the gap 101 between the straight pipe portion 22 and the nozzle body 64 shown in FIG. 2 has a dimension of 0.5 mm on a radial line extending from the central axis to one side in the radial direction.

電解生成物混合装置11は、ノズル本体64が異なる導入ノズル25を複数種類、具体的には図4に示すように4種類備えている。以下の説明において、これらを区別する必要がある場合、導入ノズル25(A)、導入ノズル25(B)、導入ノズル25(C)、導入ノズル25(D)、として区別する。そして、それぞれに関連する部位についても同様に符号に(A),(B),(C),(D)を付して区別する。   The electrolytic product mixing apparatus 11 includes a plurality of types of introduction nozzles 25 having different nozzle bodies 64, specifically, four types as shown in FIG. In the following description, when these need to be distinguished, they are distinguished as an introduction nozzle 25 (A), an introduction nozzle 25 (B), an introduction nozzle 25 (C), and an introduction nozzle 25 (D). The parts related to each are similarly distinguished by adding (A), (B), (C), (D) to the reference numerals.

電解生成物混合装置11は、図4(a)に示すノズル本体64(A)を有する導入ノズル25(A)と、この導入ノズル25(A)のノズル本体64(A)に対し長さが同じで太さが太い図4(b)に示すノズル本体64(B)を有する導入ノズル25(B)と、ノズル本体64(A)に対し長さが長く太さが同じ図4(c)に示すノズル本体64(C)を有する導入ノズル25(C)と、ノズル本体64(A)に対し長さが長く太さが太い図4(d)に示すノズル本体64(D)を有する導入ノズル25(D)とを備えている。ノズル本体64(D)は、ノズル本体64(C)と長さが同じであり、ノズル本体64(B)と太さが同じとなっている。つまり、ノズル本体64(A)〜64(D)の中で、ノズル本体64(A)は短くて細く、ノズル本体64(B)は短くて太く、ノズル本体64(C)は長くて細く、ノズル本体64(D)は長くて太い。   The electrolytic product mixing apparatus 11 has an introduction nozzle 25 (A) having a nozzle body 64 (A) shown in FIG. 4A and a length relative to the nozzle body 64 (A) of the introduction nozzle 25 (A). The introduction nozzle 25 (B) having the nozzle body 64 (B) shown in FIG. 4B having the same thickness and the same thickness, and FIG. 4C having a longer length than the nozzle body 64 (A) and the same thickness. An introduction nozzle 25 (C) having a nozzle body 64 (C) shown in FIG. 4 and an introduction nozzle having a nozzle body 64 (D) shown in FIG. And a nozzle 25 (D). The nozzle body 64 (D) has the same length as the nozzle body 64 (C) and the same thickness as the nozzle body 64 (B). That is, among the nozzle bodies 64 (A) to 64 (D), the nozzle body 64 (A) is short and thin, the nozzle body 64 (B) is short and thick, and the nozzle body 64 (C) is long and thin. The nozzle body 64 (D) is long and thick.

ここで、これらの導入ノズル25(A)〜25(D)は、取付部85およびユニオンナット26が共通の形状となっており、よって、いずれもユニオンナット26で同一の基端管部43に対し着脱自在となっている。言い換えれば、導入ノズル25(A)〜25(D)は、いずれも同一のチーズ管24の基端管部43に対し着脱自在となっており、択一的に選択されて同一のチーズ管24の基端管部43に取り付けられる。さらに言い換えれば、一つのみの導入ノズル25の取付部85を基端管部43に着脱自在に連結する着脱連結部86は、これら導入ノズル25(A)〜25(D)に対して共通の形状であって、これら導入ノズル25(A)〜25(D)のすべてを基端管部43に連結可能となっている。つまり、導入ノズル25(A)〜25(D)は、同一のチーズ管24の基端管部43に対し交換しての取り付けが可能となっている。   Here, in these introduction nozzles 25 (A) to 25 (D), the mounting portion 85 and the union nut 26 have a common shape. Therefore, both of the introduction nozzles 25 (A) to 25 (D) are connected to the same proximal end tube portion 43 by the union nut 26. On the other hand, it is detachable. In other words, the introduction nozzles 25 (A) to 25 (D) are all detachable from the proximal end tube portion 43 of the same cheese tube 24, and are alternatively selected to be the same cheese tube 24. It is attached to the proximal end pipe part 43 of the. In other words, the attachment / detachment connecting portion 86 for detachably connecting the attachment portion 85 of only one introduction nozzle 25 to the proximal end tube portion 43 is common to these introduction nozzles 25 (A) to 25 (D). All of the introduction nozzles 25 (A) to 25 (D) can be connected to the proximal end pipe portion 43. That is, the introduction nozzles 25 (A) to 25 (D) can be attached by being exchanged with respect to the proximal end pipe portion 43 of the same cheese pipe 24.

これらの導入ノズル25(A)〜25(D)が択一的にチーズ管24の基端管部43に取り付けられると、他の導入ノズル25が取り付けられる場合と比べて、直管部22との間の間隙101の長さおよび断面積のうちの少なくともいずれか一方が変更される。つまり、図5(a)に示すように、これらの導入ノズル25(A)〜25(D)の中から導入ノズル25(A)が選択されて基端管部43に取り付けられた場合の間隙101(A)の長さおよび断面積を基準とすると、ノズル本体64(A)に対し長さが同じで太さが太い図5(b)に示すノズル本体64(B)を有する導入ノズル25(B)が選択されて基端管部43に取り付けられると、間隙101(B)は、間隙101(A)に対し長さは同じで断面積が小さくなる。また、ノズル本体64(A)に対し長さが長く太さが同じ図5(c)に示すノズル本体64(C)を有する導入ノズル25(C)が選択されて基端管部43に取り付けられると、間隙101(C)は、間隙101(A)に対し断面積が同じで長さが長くなる。また、ノズル本体64(A)に対し長さが長く太さが太い図5(d)に示すノズル本体64(D)を有する導入ノズル25(D)が選択されて基端管部43に取り付けられると、間隙101(D)は、間隙101(A)に対し断面積が小さく長さが長くなる。   When these introduction nozzles 25 (A) to 25 (D) are alternatively attached to the proximal end pipe portion 43 of the cheese pipe 24, the straight pipe portion 22 is compared with the case where the other introduction nozzles 25 are attached. At least one of the length of the gap 101 and the cross-sectional area is changed. That is, as shown in FIG. 5A, the gap when the introduction nozzle 25 (A) is selected from these introduction nozzles 25 (A) to 25 (D) and attached to the proximal end pipe portion 43. With reference to the length and cross-sectional area of 101 (A), the introduction nozzle 25 having the nozzle body 64 (B) shown in FIG. When (B) is selected and attached to the proximal end pipe portion 43, the gap 101 (B) has the same length as the gap 101 (A) and the sectional area becomes smaller. Further, the introduction nozzle 25 (C) having the nozzle body 64 (C) shown in FIG. 5C having the same length and the same thickness as the nozzle body 64 (A) is selected and attached to the proximal end pipe portion 43. As a result, the gap 101 (C) has the same cross-sectional area as the gap 101 (A) and a longer length. In addition, the introduction nozzle 25 (D) having the nozzle body 64 (D) shown in FIG. 5D that is long and thick with respect to the nozzle body 64 (A) is selected and attached to the proximal end pipe portion 43. As a result, the gap 101 (D) has a smaller cross-sectional area and a longer length than the gap 101 (A).

言い換えれば、電解生成物混合装置11は、その吸引混合装置21が、直管部22との間の間隙101の長さおよび断面積のうちの少なくともいずれか一方を変更可能な複数種類の導入ノズル25(A)〜25(D)を備えており、これら導入ノズル25(A)〜25(D)が基端管部43に択一的に取り付けられる。さらに言い換えれば、この電解生成物混合装置11を用いて塩素ガスを原水に混合する電解生成物混合方法は、複数種類の導入ノズル25(A)〜25(D)を準備し、これら導入ノズル25(A)〜25(D)を基端管部43に択一的に取り付けることで、基端管部43に取り付けられた導入ノズル25と直管部22との間の間隙101の長さおよび断面積のうちの少なくともいずれか一方を変更する。   In other words, the electrolytic product mixing device 11 includes a plurality of types of introduction nozzles whose suction mixing device 21 can change at least one of the length and the cross-sectional area of the gap 101 with the straight pipe portion 22. 25 (A) to 25 (D), and these introduction nozzles 25 (A) to 25 (D) are alternatively attached to the proximal end pipe portion 43. In other words, the electrolytic product mixing method of mixing chlorine gas with raw water using the electrolytic product mixing device 11 prepares a plurality of types of introduction nozzles 25 (A) to 25 (D), and these introduction nozzles 25. By selectively attaching (A) to 25 (D) to the proximal end pipe part 43, the length of the gap 101 between the introduction nozzle 25 attached to the proximal end pipe part 43 and the straight pipe part 22, and At least one of the cross-sectional areas is changed.

以上に述べた実施形態によれば、チーズ管24の基端管部43に対し着脱自在な複数種類の導入ノズル25を、択一的に基端管部43に取り付けることで、導入ノズル25と直管部22との間の間隙101の長さおよび断面積のうちの少なくともいずれか一方を変更することができる。よって、チーズ管24を交差管部23から先端管部44に向けて流れて導入ノズル25の内孔95から塩素ガスを吸引して混合させる原水が、導入ノズル25と直管部22との間の間隙101を通って流れる際の流量を変更することができる。したがって、原水の流量を容易に変更することができる。   According to the embodiment described above, a plurality of types of introduction nozzles 25 that are detachable from the proximal end pipe part 43 of the cheese tube 24 are alternatively attached to the proximal end pipe part 43, At least one of the length of the gap 101 between the straight pipe portion 22 and the cross-sectional area can be changed. Therefore, the raw water that flows through the cheese tube 24 from the cross tube portion 23 toward the tip tube portion 44 and sucks and mixes chlorine gas from the inner hole 95 of the introduction nozzle 25 is between the introduction nozzle 25 and the straight tube portion 22. The flow rate when flowing through the gap 101 can be changed. Therefore, the flow rate of raw water can be easily changed.

具体的には、図5(a)に示すように、ノズル本体64(A)を有する導入ノズル25(A)が選択されて基端管部43に取り付けられた場合は、四本の導入ノズル25(A)〜25(D)のそれぞれが取り付けられた場合の中で、最も原水の流量が多くなる。この流量を基準とすると、ノズル本体64(A)に対し長さが同じで太さが太い図5(b)に示すノズル本体64(B)を有する導入ノズル25(B)が基端管部43に取り付けられると、間隙101(B)は、間隙101(A)に対し長さは同じものの断面積が小さくなるため、原水の流量が減ることになる。また、ノズル本体64(A)に対し長さが長く太さが同じ図5(c)に示すノズル本体64(C)を有する導入ノズル25(C)が基端管部43に取り付けられると、間隙101(C)は、間隙101(A)に対し断面積が同じものの長さが長くなるため、圧力損失により原水の流量が減ることになる。また、ノズル本体64(A)に対し長さが長く太さが太い図5(d)に示すノズル本体64(D)を有する導入ノズル25(D)が基端管部43に取り付けられると、間隙101(D)は、間隙101(A)に対し断面積が小さく長さが長くなるため、原水の流量が減ることになる。この導入ノズル25(D)が取り付けられた場合が、四本の導入ノズル25(A)〜25(D)のそれぞれが取り付けられた場合の中で、最も原水の流量が減ることになる。   Specifically, as shown in FIG. 5A, when the introduction nozzle 25 (A) having the nozzle body 64 (A) is selected and attached to the proximal end pipe portion 43, four introduction nozzles are provided. In the case where each of 25 (A) to 25 (D) is attached, the flow rate of the raw water is the largest. Based on this flow rate, the introduction nozzle 25 (B) having the nozzle body 64 (B) shown in FIG. When attached to 43, the gap 101 (B) has the same length as the gap 101 (A) but has a smaller cross-sectional area, so the flow rate of the raw water is reduced. When the introduction nozzle 25 (C) having the nozzle body 64 (C) shown in FIG. 5C having the same length and the same thickness as the nozzle body 64 (A) is attached to the proximal end pipe portion 43, Since the gap 101 (C) has the same cross-sectional area as the gap 101 (A), the length of the gap 101 (C) is increased, so that the flow rate of raw water is reduced due to pressure loss. When the introduction nozzle 25 (D) having the nozzle body 64 (D) shown in FIG. 5 (d) that is long and thick with respect to the nozzle body 64 (A) is attached to the proximal end pipe portion 43. Since the gap 101 (D) has a smaller cross-sectional area and a longer length than the gap 101 (A), the flow rate of the raw water is reduced. When the introduction nozzle 25 (D) is attached, the flow rate of the raw water is reduced most in the case where each of the four introduction nozzles 25 (A) to 25 (D) is attached.

ここで、電解槽14による塩素ガスの発生量が一定の場合、原水の流量が増えると、混合後の原水の塩素濃度は低くなり、原水の流量が増えると、混合後の原水の塩素濃度は高くなる。また、電解槽14による塩素ガスの発生量を制御することで、混合後の原水の流量を、塩素濃度を一定のまま増減させることができる。   Here, when the amount of chlorine gas generated by the electrolytic cell 14 is constant, the chlorine concentration of the raw water after mixing decreases as the flow rate of the raw water increases, and the chlorine concentration of the raw water after mixing increases as the flow rate of the raw water increases. Get higher. Further, by controlling the amount of chlorine gas generated by the electrolytic cell 14, the flow rate of the raw water after mixing can be increased or decreased with the chlorine concentration kept constant.

電解生成物混合装置の一例としての電解水製造装置のこれまでのものは、装置の能力により、設備の規模がほぼ固定されていた。したがって、一度設備が完成すると製造能力の変更には多大な費用と労力を要した。また、大型の装置や設備は、新設時には比較的導入が容易であるが、既存の設備に組み込むには困難なことが多かった。通常、電解水製造装置は、流量や電解能力、電解槽の大きさは、製造装置の形式ごとに決まっており、製造元によって、複数の製品仕様が用意されている。顧客はそれに合わせて、最適なものを選択することになる。その際、オーバスペックや、能力不足などが生じることがある。また、能力だけの問題ではなく、配管の配置や装置の大きさ、形状等が、既存の設備には入らないなど欠点もある。これまでは一能力に対して一機種であり、能力変更には、装置本体の交換、すなわち別の商品、または複数台の装置を準備する必要であった。これに対して、本実施形態の電解生成物混合装置11は、これとは異なる構造の既設の電解生成物混合装置に対して、吸引混合装置21を交換するだけで能力の変更が可能となり、低コストで能力を変更することができる。   In the conventional electrolyzed water production apparatus as an example of the electrolysis product mixing apparatus, the scale of the facility is almost fixed by the capacity of the apparatus. Therefore, once the equipment is completed, changing the production capacity requires a large amount of money and labor. Large equipment and facilities are relatively easy to introduce at the time of new construction, but are often difficult to incorporate into existing facilities. Usually, the electrolyzed water production apparatus has a flow rate, an electrolysis capacity, and an electrolyzer size that are determined for each type of production apparatus, and a plurality of product specifications are prepared by the manufacturer. The customer will choose the best one accordingly. At that time, over-specification, lack of capability, etc. may occur. Moreover, it is not only a problem of capacity, but also has a drawback that the arrangement of piping and the size and shape of the apparatus do not fit into existing facilities. Until now, there was one model for one capability, and changing the capability required replacement of the device body, that is, preparation of another product or a plurality of devices. On the other hand, the electrolytic product mixing device 11 of the present embodiment can change the capacity by simply replacing the suction mixing device 21 with respect to the existing electrolytic product mixing device having a different structure, Capability can be changed at low cost.

また、装置のコストダウンを考えた場合、部品の共通化などを考慮すると製品アイテム数は、少ないほどよい。しかし、顧客の要望にこたえるためには、多数のアイテムを用意する必要があり、コスト高になる。さらに製品としての在庫もある程度抱えていなければならない問題もあった。これに対して、本実施形態の電解生成物混合装置11は、導入ノズル25を交換するだけで能力の変更が可能となり、他の部品は共通化できるため、製品アイテム数を多くしても実質的に導入ノズル25のアイテム数を多くすることで対応でき、在庫の総量も減らすことができる。   Also, when considering the cost reduction of the apparatus, the smaller the number of product items, the better as the parts are shared. However, in order to meet the customer's request, it is necessary to prepare a large number of items, which increases the cost. In addition, there was a problem that had some inventory as a product. On the other hand, the electrolytic product mixing apparatus 11 of the present embodiment can change the capacity only by replacing the introduction nozzle 25 and can share other parts. Therefore, even if the number of product items is increased, In particular, the number of items in the introduction nozzle 25 can be increased, and the total amount of inventory can be reduced.

また、導入ノズル25が着脱自在であるため、導入ノズル25の点検保守を容易に行うことができる。   In addition, since the introduction nozzle 25 is detachable, inspection and maintenance of the introduction nozzle 25 can be easily performed.

また、導入ノズル25の内孔95の先端部が、先端に向けて拡径するテーパ形状に形成されているため、電解生成物である塩素ガスを効率良く吸引することができる。   Further, since the tip end portion of the inner hole 95 of the introduction nozzle 25 is formed in a tapered shape whose diameter increases toward the tip end, chlorine gas as an electrolytic product can be efficiently sucked.

また、導入ノズル25の基端部に、基端管部43に当接して直管部22内への導入ノズル25の挿入長さを規定する当接部91が設けられているため、導入ノズル25をチーズ管24に取り付ける際に、当接部91を基端管部43に当接させれば、直管部22内への導入ノズル25の挿入長さを規定できることになる。よって、チーズ管24に対して導入ノズル25の位置決めを容易に行うことができる。したがって、原水への塩素ガスの混合を適切かつ一定にすることができる。   In addition, since the proximal end portion of the introduction nozzle 25 is provided with an abutment portion 91 that abuts the proximal end tube portion 43 and defines the insertion length of the introduction nozzle 25 into the straight tube portion 22, the introduction nozzle When the abutment portion 91 is brought into contact with the proximal end tube portion 43 when the 25 is attached to the cheese tube 24, the insertion length of the introduction nozzle 25 into the straight tube portion 22 can be defined. Therefore, the introduction nozzle 25 can be easily positioned with respect to the cheese tube 24. Therefore, the mixing of chlorine gas into the raw water can be made appropriate and constant.

ここで、複数種類の導入ノズル25のすべてを連結可能であって、複数種類の導入ノズル25のうちの一つのみの取付部85をチーズ管24の基端管部43に着脱自在に連結する着脱連結部86としては、上記したユニオンジョイント構造の着脱連結部86以外を採用することも可能である。   Here, all of the plurality of types of introduction nozzles 25 can be connected, and only one mounting portion 85 of the plurality of types of introduction nozzles 25 is detachably connected to the proximal end tube portion 43 of the cheese tube 24. As the attachment / detachment connecting portion 86, it is possible to adopt other than the attachment / detachment connecting portion 86 having the above-described union joint structure.

例えば、図6に示すように、図2に示すユニオンナット26をなくすとともにユニオンボルト62に換えて取付部材121をベース63(図6では図示略)に固定する。この取付部材121の接続管体65とは反対側の端部には径方向外方に突出する円環状のフランジ部122が設けられている。そして、基端管部43のフランジ部48と、フランジ部122とを当接させて、これらフランジ部48,122をクリップ部材123で挟持する。このクリップ部材123は、帯状の板材を曲げ加工して形成されるもので弾性変形可能となっている。このクリップ部材123には、嵌合溝124が形成されており、嵌合溝124にフランジ部48,122を並べて同時に嵌合させることでフランジ部48,122を挟持する。この場合、フランジ部48,122とクリップ部材123とが、複数種類の導入ノズル25のすべてを連結可能であって、複数種類の導入ノズル25のうちの一つのみを基端管部43に着脱自在に連結する着脱連結部125を構成することになり、取付部材121のフランジ部122の先端部が、基端管部43に当接して直管部22内への導入ノズル25(図6では図示略)の挿入長さを規定する当接部126となる。   For example, as shown in FIG. 6, the union nut 26 shown in FIG. 2 is eliminated, and the mounting member 121 is fixed to a base 63 (not shown in FIG. 6) instead of the union bolt 62. An annular flange portion 122 projecting radially outward is provided at an end portion of the attachment member 121 opposite to the connection pipe body 65. Then, the flange portion 48 of the proximal end tube portion 43 and the flange portion 122 are brought into contact with each other, and the flange portions 48 and 122 are held between the clip members 123. The clip member 123 is formed by bending a band-shaped plate material and is elastically deformable. The clip member 123 is formed with a fitting groove 124, and the flange parts 48 and 122 are clamped by arranging the flange parts 48 and 122 in the fitting groove 124 and fitting them together at the same time. In this case, the flange portions 48 and 122 and the clip member 123 can connect all of the plurality of types of introduction nozzles 25, and only one of the plurality of types of introduction nozzles 25 is attached to and detached from the proximal end tube portion 43. The detachable connecting portion 125 that is freely connected is configured, and the distal end portion of the flange portion 122 of the mounting member 121 abuts on the proximal end tube portion 43 and is introduced into the straight tube portion 22 (in FIG. 6). The contact portion 126 defines the insertion length (not shown).

また、例えば、図7に示すように、図2に示すユニオンナット26をなくすとともにユニオンボルト62に換えて有孔円板状の取付部材131をベース63に固定する。また、基端管部43のフランジ部48の外径を取付部材131に合わせて大きくする。そして、取付部材131とフランジ部48とで有孔円板状のパッキン132を挟持した状態で、取付部材131とフランジ部48とをボルト133およびナット134を含む複数の締結具135で締結する。この場合、取付部材131とフランジ部48とパッキン132と複数の締結具135とが、複数種類の導入ノズル25のすべてを連結可能であって、複数種類の導入ノズル25のうちの一つのみを基端管部43に着脱自在に連結する着脱連結部136を構成することになる。   Further, for example, as shown in FIG. 7, the union nut 26 shown in FIG. 2 is eliminated, and a perforated disk-shaped attachment member 131 is fixed to the base 63 instead of the union bolt 62. Further, the outer diameter of the flange portion 48 of the proximal end tube portion 43 is increased in accordance with the mounting member 131. The mounting member 131 and the flange portion 48 are fastened by a plurality of fasteners 135 including bolts 133 and nuts 134 with the perforated disk-shaped packing 132 sandwiched between the mounting member 131 and the flange portion 48. In this case, the mounting member 131, the flange portion 48, the packing 132, and the plurality of fasteners 135 can connect all of the plurality of types of introduction nozzles 25, and only one of the plurality of types of introduction nozzles 25 can be connected. The detachable connecting portion 136 that is detachably connected to the proximal end tube portion 43 is configured.

また、例えば、図8に示すように、図2に示すユニオンナット26をなくすとともにユニオンボルト62に換えて取付部材141をベース63(図8では図示略)に固定する。この取付部材141は、軸方向の中間部に径方向外方に突出する円環状のフランジ部142が形成されており、先端側の外周部にオネジ143が、オネジ143よりも先端側に円環状の溝144が形成されている。また、基端管部43に軸方向に延出する円筒状の筒状部148を形成し、その内周部にメネジ149を形成する。そして、取付部材141の先端の溝144にOリング150を配置して、取付部材141のオネジ143を基端管部43のメネジ149に、フランジ部142が筒状部148に当接するまで螺合させる。この場合、オネジ143とメネジ149とが、複数種類の導入ノズル25のすべてを連結可能であって、複数種類の導入ノズル25のうちの一つのみを基端管部43に着脱自在に連結する着脱連結部151を構成することになり、フランジ部142のオネジ143側の端部が、基端管部43に当接して直管部22内への導入ノズル25の挿入長さを規定する当接部152となる。   Further, for example, as shown in FIG. 8, the union nut 26 shown in FIG. 2 is eliminated, and the mounting member 141 is fixed to the base 63 (not shown in FIG. 8) instead of the union bolt 62. The mounting member 141 is formed with an annular flange portion 142 projecting radially outward at an axially intermediate portion, a male screw 143 on the outer peripheral portion on the tip side, and an annular shape on the tip side of the male screw 143. The groove 144 is formed. Further, a cylindrical tubular portion 148 extending in the axial direction is formed in the proximal end tube portion 43, and a female screw 149 is formed on the inner peripheral portion thereof. Then, the O-ring 150 is disposed in the groove 144 at the distal end of the mounting member 141, and the male screw 143 of the mounting member 141 is screwed into the female screw 149 of the proximal end tube portion 43 until the flange portion 142 comes into contact with the cylindrical portion 148. Let In this case, the male screw 143 and the female screw 149 can connect all of the plurality of types of introduction nozzles 25, and only one of the plurality of types of introduction nozzles 25 is detachably connected to the proximal end tube portion 43. The detachable connecting portion 151 is configured, and the end portion of the flange portion 142 on the male screw 143 side is in contact with the proximal end tube portion 43 to regulate the insertion length of the introduction nozzle 25 into the straight tube portion 22. It becomes the contact part 152.

また、図9に示すように、導入ノズル25のベース63に、内孔95に繋がる塩素ガスの導入口161を複数形成することも可能である。この場合、電解槽14の接続数を増減させて塩素ガスの供給量を増減させることができる。   Further, as shown in FIG. 9, a plurality of chlorine gas inlets 161 connected to the inner hole 95 can be formed in the base 63 of the inlet nozzle 25. In this case, the supply amount of chlorine gas can be increased or decreased by increasing or decreasing the number of connections of the electrolytic cell 14.

また、図10(a)に示すように、テーパ孔部105と円筒孔部106とを有する上記した導入ノズル25の形状以外に、他の形状を採用することも可能である。例えば、図10(b)に示すように、テーパ孔部105と円筒孔部106との間にテーパ孔部105側ほど小径となる逆テーパ孔部171を設けたり、図10(c)に示すように、ノズル本体64の先端側の外周部に先端側ほど小径となるテーパ外周面172を形成して外径が先端で窄む形状とするとともに内孔95の径を全体に亘って一定としたり、図10(d)に示すように、ノズル本体64の外径つまり外周面96の径を先端まで一定とし内孔95の径を全体に亘って一定としたり、図10(e)に示すように、ノズル本体64の先端側の外周部に円環状のV字溝173を形成したりすることが可能である。   In addition to the shape of the introduction nozzle 25 having the tapered hole portion 105 and the cylindrical hole portion 106 as shown in FIG. 10A, other shapes can be employed. For example, as shown in FIG. 10B, a reverse tapered hole 171 having a smaller diameter toward the tapered hole 105 side is provided between the tapered hole 105 and the cylindrical hole 106, or as shown in FIG. As described above, a tapered outer peripheral surface 172 having a smaller diameter toward the distal end side is formed on the outer peripheral portion on the distal end side of the nozzle body 64 so that the outer diameter is narrowed at the distal end, and the diameter of the inner hole 95 is made constant throughout As shown in FIG. 10D, the outer diameter of the nozzle body 64, that is, the diameter of the outer peripheral surface 96 is made constant up to the tip, and the diameter of the inner hole 95 is made constant throughout, or as shown in FIG. Thus, an annular V-shaped groove 173 can be formed on the outer peripheral portion of the nozzle body 64 on the tip side.

ここで、内孔95の径が先端部において先端に向かってテーパ状に漸次拡径した導入ノズル25(図10(a)参照)と、内孔95の径が全体に亘って一定の導入ノズル25(図10(c)参照)とを用い、異なる長さの導入ノズル25をチーズ管24に装着した場合の吸引圧を試験した。なお、この試験において、導入ノズル25の長さおよび内孔95の先端部の形状以外の条件は一定とした。その結果を図11に示す。図11に示すように、図10(c)の内孔95の径が全体に亘って一定の導入ノズル25(図11の通常ノズル)に比べると、図10(a)の内孔95の径が先端部において先端に向かってテーパ状に漸次拡径した導入ノズル25(図11の開口ノズル)の方が吸引圧の絶対値が大きくなり、強く吸引できることがわかった。   Here, the introduction nozzle 25 (see FIG. 10A) in which the diameter of the inner hole 95 gradually increases in a tapered shape toward the tip at the tip, and the introduction nozzle in which the diameter of the inner hole 95 is constant throughout. 25 (see FIG. 10C), the suction pressure when the introduction nozzles 25 of different lengths were attached to the cheese tube 24 was tested. In this test, conditions other than the length of the introduction nozzle 25 and the shape of the tip of the inner hole 95 were constant. The result is shown in FIG. As shown in FIG. 11, the diameter of the inner hole 95 in FIG. 10A is larger than that of the introduction nozzle 25 (normal nozzle in FIG. 11) where the diameter of the inner hole 95 in FIG. It was found that the suction nozzle 25 (opening nozzle in FIG. 11) whose diameter gradually increased in a tapered shape toward the tip at the tip has a larger absolute value of suction pressure and can be sucked strongly.

図10(c)に示した外径が先端で窄む導入ノズル25の場合、間隙101が混合部111の直前で大きくなり流速が下がって負圧が小さくなるため、塩素ガスの吸引圧が下がることがある。しかし、図10(d)のように外径が一定の導入ノズル25であれば負圧が低下することを防止することができる。このため、導入ノズル25の外径が先端で窄まないことが好ましい。以上に鑑みると、図10(a),(b)の導入ノズル25がより吸引圧を上げることができる。   In the case of the introduction nozzle 25 whose outer diameter is narrowed at the tip as shown in FIG. 10C, the gap 101 becomes large immediately before the mixing section 111, the flow velocity is lowered, and the negative pressure is reduced, so that the suction pressure of chlorine gas is lowered. Sometimes. However, if the introduction nozzle 25 has a constant outer diameter as shown in FIG. 10D, the negative pressure can be prevented from decreasing. For this reason, it is preferable that the outer diameter of the introduction nozzle 25 is not constricted at the tip. In view of the above, the introduction nozzle 25 of FIGS. 10A and 10B can further increase the suction pressure.

したがって、吸引圧を変更したい場合に備えて、内孔95の先端のテーパ孔部105の角度を異ならせた導入ノズル25を複数用意しておくことが好ましい。また、塩素ガスの流量を変更させるために、内孔95の円筒孔部106の内径を異ならせた複数種類の導入ノズル25を用意しておいてもよく、さらには、内孔95のテーパ孔部105の内径および円筒孔部106の内径を両方適宜異ならせた複数種類の交換可能な導入ノズル25を用意しておいてもよい。   Therefore, it is preferable to prepare a plurality of introduction nozzles 25 with different angles of the tapered hole portion 105 at the tip of the inner hole 95 in preparation for changing the suction pressure. In order to change the flow rate of chlorine gas, a plurality of types of introduction nozzles 25 having different inner diameters of the cylindrical hole portion 106 of the inner hole 95 may be prepared. A plurality of types of replaceable introduction nozzles 25 in which the inner diameter of the portion 105 and the inner diameter of the cylindrical hole portion 106 are appropriately different may be prepared.

上述した電解生成物混合装置11は、水に電解生成物としての塩素ガスを混合して電解水を生成することにより、電解水製造装置を構成する。例えば、図12に示すように、所定の濃度の塩酸水を電気分解して塩素ガスを発生させる電解槽14と、水を供給する給水管181とを備えた電解水製造装置182を構成する。図12に示す電解水製造装置182は、複数の電解槽14のそれぞれの導出口183に取り付けられた配管184が、導入ノズル25の複数の導入口161に接続され、原水として例えば加圧された水道水を給水する給水管181が交差管部23に接続されている。電解水製造装置182の駆動時には、吸引混合装置21の交差管部23に水が供給され、図9に示す交差管部23の内側開口部33の位置から間隙101に水が高速で浸入して流動する。一方、電解槽14内では塩酸水の電気分解が進む。間隙101を通過して直管部22の導入ノズル25よりも前方に流れた水が、導入ノズル25の内孔95を吸引し、その結果、図12に示す電解槽14の導出口183に接続された配管184を経由して、生成された塩素ガスが、図9に示す内孔95から混合部111に噴出し直管部22内の水に混合される。   The electrolyzed product mixing apparatus 11 described above constitutes an electrolyzed water production apparatus by mixing water with chlorine gas as an electrolyzed product to produce electrolyzed water. For example, as shown in FIG. 12, an electrolyzed water production apparatus 182 including an electrolyzer 14 that electrolyzes hydrochloric acid having a predetermined concentration to generate chlorine gas and a water supply pipe 181 that supplies water is configured. In the electrolyzed water production apparatus 182 shown in FIG. 12, the pipes 184 attached to the respective outlets 183 of the plurality of electrolytic cells 14 are connected to the plurality of inlets 161 of the introduction nozzle 25 and pressurized, for example, as raw water. A water supply pipe 181 for supplying tap water is connected to the cross pipe portion 23. When the electrolyzed water production apparatus 182 is driven, water is supplied to the cross pipe section 23 of the suction mixing apparatus 21 and water enters the gap 101 at a high speed from the position of the inner opening 33 of the cross pipe section 23 shown in FIG. To flow. On the other hand, electrolysis of hydrochloric acid water proceeds in the electrolytic cell 14. The water that has passed through the gap 101 and has flowed forward from the introduction nozzle 25 of the straight pipe portion 22 sucks the inner hole 95 of the introduction nozzle 25, and as a result, is connected to the outlet 183 of the electrolytic cell 14 shown in FIG. The generated chlorine gas is ejected from the inner hole 95 shown in FIG. 9 to the mixing unit 111 and mixed with the water in the straight pipe unit 22 through the pipe 184 formed.

また、上述した電解生成物混合装置11は、原水に電解生成物としての塩素ガスを混合して原水を殺菌処理または消臭処理することにより、処理装置を構成する。この場合の原水は、例えばプールの水、入浴設備の入浴水、浄水場の浄化対象水、下水、排水、船舶のバラスト水等である。   Moreover, the electrolysis product mixing apparatus 11 mentioned above comprises a processing apparatus by mixing the raw | natural water with the chlorine gas as an electrolysis product, and sterilizing or deodorizing raw | natural water. The raw water in this case is, for example, pool water, bath water of bathing facilities, purification target water of a water purification plant, sewage, drainage, ship ballast water, or the like.

船舶用のバラスト水を浄化処理するバラスト水処理装置としては、例えば、図13に示すように、海水を船舶のバラスト水タンク194に注水するバラスト水処理装置191がある。このバラスト水処理装置191は、バラスト水タンク194に海水を送水する管路195と、この管路195に設けられ海水を汲み上げるポンプ192と、ポンプ192で汲み上げられて圧送されるバラスト水となる海水を濾過するフィルタ193とを有している。そして、このバラスト水処理装置191では、フィルタ193で濾過後の海水に電解生成物としての塩素ガスを混合するために上記した電気分解モジュール16と吸引混合装置21とからなる電解生成物混合装置11が用いられる。つまり、フィルタ193で濾過後の海水の全量を吸引混合装置21の交差管部23に導入することで、海水に塩素ガスを混合して海水を殺菌処理する。塩素ガスが混合された後の海水を船舶のバラスト水タンク194に注水する。なお、この場合、フィルター193の位置、ポンプ192の位置は適宜変更することが可能であり、例えば、フィルター193をポンプ192の上流に配置しても良く、電解生成物混合装置11の下流に配置しても良い。また、ポンプ192を電解生成物混合装置11の下流に配置しても良い。このような点は、以下の図14〜図16に示す態様でも同様である。   As a ballast water treatment apparatus for purifying ballast water for ships, for example, as shown in FIG. 13, there is a ballast water treatment apparatus 191 for pouring seawater into a ballast water tank 194 of the ship. The ballast water treatment apparatus 191 includes a pipe 195 for feeding seawater to the ballast water tank 194, a pump 192 provided in the pipe 195 for pumping seawater, and seawater to be ballast water pumped and pumped by the pump 192. And a filter 193 for filtering. And in this ballast water treatment apparatus 191, in order to mix the chlorine gas as an electrolysis product with the seawater filtered by the filter 193, the electrolysis product mixing apparatus 11 which consists of the electrolysis module 16 and the suction mixing apparatus 21 mentioned above is mixed. Is used. That is, by introducing the entire amount of seawater filtered by the filter 193 into the cross pipe portion 23 of the suction mixing device 21, the seawater is sterilized by mixing chlorine gas with the seawater. Seawater after the chlorine gas is mixed is poured into a ballast water tank 194 of the ship. In this case, the position of the filter 193 and the position of the pump 192 can be appropriately changed. For example, the filter 193 may be arranged upstream of the pump 192 or arranged downstream of the electrolytic product mixing device 11. You may do it. Further, the pump 192 may be arranged downstream of the electrolytic product mixing device 11. Such a point is also the same in the embodiments shown in FIGS.

また、図14に示すように、海水を船舶のバラスト水タンク194に注水する他のバラスト水処理装置201として、上記と同様のポンプ192とフィルタ193とを管路195に有し、フィルタ193で濾過後の海水を船舶のバラスト水タンク194に注水する主ルート202から一部の海水をバイパスさせるバイパスルート203を設け、このバイパスルート203を流れる一部の海水に電解生成物混合装置11で塩素ガスを混合するものがある。このバラスト水処理装置201では、吸引混合装置21の交差管部23にバイパスルート203の海水を導入することで、この海水に塩素ガスを混合して海水を殺菌処理する。そして、このように塩素ガスを混合した海水を、主ルート202に合流させて主ルート202を流れる海水に混合させて殺菌処理し船舶のバラスト水タンク194に注水する。この場合、バイパスルート203の海水に、電解生成物混合装置11で高濃度となるように塩素ガスを混合し、このバイパスルート203の海水を主ルート202を流れる海水に混合後、海水の塩素ガスの濃度が所望の濃度となるように混合を調整する。つまり、このバラスト水処理装置201は、塩素濃度が高濃度のバラスト水を希釈する方式のものである。   Further, as shown in FIG. 14, as another ballast water treatment apparatus 201 for pouring seawater into a ballast water tank 194 of a ship, a pipe 195 and a filter 193 similar to the above are provided in a pipe 195, and the filter 193 A bypass route 203 for bypassing a part of the seawater from the main route 202 for pouring the filtered seawater into the ballast water tank 194 of the ship is provided, and the seawater flowing through the bypass route 203 is subjected to chlorine by the electrolytic product mixing device 11. Some mix gas. In this ballast water treatment device 201, seawater of the bypass route 203 is introduced into the cross pipe portion 23 of the suction mixing device 21, so that chlorine gas is mixed with the seawater to sterilize the seawater. Then, the seawater mixed with chlorine gas in this way is joined to the main route 202 and mixed with the seawater flowing through the main route 202 to be sterilized and poured into the ballast water tank 194 of the ship. In this case, the chlorine gas is mixed with the seawater of the bypass route 203 so as to have a high concentration by the electrolytic product mixing device 11, and the seawater of the bypass route 203 is mixed with the seawater flowing through the main route 202, and then the chlorine gas of the seawater. The mixing is adjusted so that the concentration of is the desired concentration. That is, this ballast water treatment apparatus 201 is of a type that dilutes ballast water having a high chlorine concentration.

また、図15に示すように、他のバラスト水処理装置211として、船舶のバラスト水タンク194からバラスト水を汲み上げるポンプ212を有し、ポンプ212で汲み上げられて圧送されるバラスト水に電解生成物混合装置11で塩素ガスを混合してバラスト水タンク194に戻すものがある。つまり、ポンプ212で圧送されるバラスト水の全量を、吸引混合装置21の交差管部23に導入することで、バラスト水に塩素ガスを混合してバラスト水を殺菌処理し、その後、バラスト水タンク194に戻す。このバラスト水処理装置211は、バラスト水タンク194のバラスト水を管路195を介して循環させて殺菌処理するものである。   Further, as shown in FIG. 15, as another ballast water treatment device 211, there is a pump 212 that pumps ballast water from a ballast water tank 194 of a ship, and electrolytic products are generated in the ballast water that is pumped and pumped by the pump 212. Some mixing devices 11 mix chlorine gas and return it to the ballast water tank 194. In other words, the entire amount of ballast water pumped by the pump 212 is introduced into the cross pipe portion 23 of the suction mixing device 21 so that the ballast water is sterilized by mixing chlorine gas with the ballast water, and then the ballast water tank. Return to 194. The ballast water treatment device 211 sterilizes the ballast water in the ballast water tank 194 by circulating it through a pipe line 195.

また、図16に示すように、他のバラスト水処理装置221として、上記と同様のポンプ212と管路195を有し、ポンプ212で汲み上げられて圧送されるバラスト水を船舶のバラスト水タンク194に戻す主ルート222から一部のバラスト水をバイパスさせるバイパスルート223を設け、このバイパスルート223を流れる一部のバラスト水に電解生成物混合装置11で塩素ガスを混合するものがある。このバラスト水処理装置221では、吸引混合装置21の交差管部23にバイパスルート223のバラスト水を導入することで、このバラスト水に塩素ガスを混合してバラスト水を殺菌処理する。そして、このように塩素ガスを混合したバラスト水を、主ルート222に合流させて主ルート222を流れるバラスト水に混合させて殺菌処理し船舶のバラスト水タンク194に戻す。この場合、バイパスルート223のバラスト水に電解生成物混合装置11で高濃度となるように塩素ガスを混合し、このバイパスルート223のバラスト水を主ルート222を流れるバラスト水に混合後、バラスト水の塩素濃度が所望の濃度となるように混合を調整する。このバラスト水処理装置221は、バラスト水タンク194のバラスト水を循環させて殺菌処理するものであり、塩素濃度が高濃度のバラスト水を希釈する方式のものである。   Further, as shown in FIG. 16, as another ballast water treatment device 221, a ballast water tank 194 of a ship has a pump 212 and a pipe 195 similar to those described above, and the ballast water pumped up by the pump 212 and pumped. There is a bypass route 223 for bypassing a part of the ballast water from the main route 222 to be returned to, and a part of the ballast water flowing through the bypass route 223 is mixed with chlorine gas by the electrolytic product mixing device 11. In this ballast water treatment device 221, the ballast water of the bypass route 223 is introduced into the cross pipe portion 23 of the suction mixing device 21, whereby chlorine gas is mixed with this ballast water to sterilize the ballast water. The ballast water mixed with chlorine gas in this manner is merged with the main route 222 and mixed with the ballast water flowing through the main route 222 to be sterilized and returned to the ballast water tank 194 of the ship. In this case, chlorine gas is mixed with the ballast water of the bypass route 223 so as to have a high concentration by the electrolytic product mixing device 11, and the ballast water of the bypass route 223 is mixed with the ballast water flowing through the main route 222, and then the ballast water. The mixing is adjusted so that the chlorine concentration of the water becomes the desired concentration. This ballast water treatment device 221 circulates the ballast water in the ballast water tank 194 and sterilizes it, and is a system for diluting ballast water having a high chlorine concentration.

なお、実施形態において、吸引混合装置21は、チーズ管24の直管部22が水平方向を向くように設置される場合を例示して説明したが、チーズ管24の向きはどのような向きに設定することもできる。   In addition, in embodiment, although the suction mixing apparatus 21 illustrated and demonstrated the case where the straight pipe | tube part 22 of the cheese tube 24 was installed so that it might face a horizontal direction, what direction is the direction of the cheese tube 24? It can also be set.

ここで、ノズル本体64の外径と直管部22の内径と吸引混合装置21の流量との関係について考察する。   Here, the relationship between the outer diameter of the nozzle body 64, the inner diameter of the straight pipe portion 22, and the flow rate of the suction mixing device 21 will be considered.

液体の場合、配管内を流れる流体の流量と流速の関係は次式で表される。
Q=C×A×V
ここで、Q:流量[m/s]、C:流出係数、A:流路面積[m]、V:流速[m/s]
In the case of liquid, the relationship between the flow rate of the fluid flowing in the pipe and the flow velocity is expressed by the following equation.
Q = C × A × V
Here, Q: flow rate [m 3 / s], C: outflow coefficient, A: flow path area [m 2 ], V: flow velocity [m / s]

V=√(2g×P÷ρ)
ベルヌーイの定理の応用より、
Q=C×A×√(2×P÷ρ)
ここで、P:圧力(差圧)[MPa]、ρ:流体密度[kg/m
1Pa=N/m=1[Kgm−1−2]、水の密度:ρ=1000[kg/m
V = √ (2g × P ÷ ρ)
From the application of Bernoulli's theorem,
Q = C × A × √ (2 × P ÷ ρ)
Here, P: pressure (differential pressure) [MPa], ρ: fluid density [kg / m 3 ]
1 Pa = N / m = 1 [Kgm −1 s −2 ], water density: ρ = 1000 [kg / m 3 ]

内径30.4mmの配管に外径29mmの円柱を挿入すると流体が流れる断面積Aは、
A=(15.2×15.2×3.14)−(14.5×14.5×3.14)
=65.3[mm
=6.53×10−5[m
When a cylinder with an outer diameter of 29 mm is inserted into a pipe with an inner diameter of 30.4 mm,
A = (15.2 × 15.2 × 3.14) − (14.5 × 14.5 × 3.14)
= 65.3 [mm 2 ]
= 6.53 × 10 −5 [m 2 ]

吸引混合装置21の2次側が大気開放されていると、駆動水である原水の圧力が0.2MPaのとき、流量Qは、
Q=C×A×√(2×P÷ρ)
=1×6.53×10−5×√(2×0.2×1000000÷1000)
=1.30×10−3[m/s]
=4.64[m/h]
When the secondary side of the suction mixing device 21 is open to the atmosphere, when the pressure of the raw water that is the driving water is 0.2 MPa, the flow rate Q is
Q = C × A × √ (2 × P ÷ ρ)
= 1 × 6.53 × 10 −5 × √ (2 × 0.2 × 1000000 ÷ 1000)
= 1.30 × 10 −3 [m 3 / s]
= 4.64 [m 3 / h]

近似値で実測すると0.195MPaのとき流量は4.05[m/h]であった。
流出係数C=1と仮定して計算すると4.64[m]の流量である。
このことから、流出係数は4.05/4.64=0.873となり、これを0.9として計算すると、流量は4.18[m/h]であった。
When measured by an approximate value, the flow rate was 4.05 [m 3 / h] at 0.195 MPa.
When the calculation is made assuming that the outflow coefficient C = 1, the flow rate is 4.64 [m 3 ].
From this, the outflow coefficient was 4.05 / 4.64 = 0.873. When this was calculated as 0.9, the flow rate was 4.18 [m 3 / h].

流出係数を0.9として計算すると以下の表1のとおり、導入ノズル25のノズル本体64の外径、およびチーズ管24の直管部22の内径に関係なく、理論通りの設計が可能である。   When the outflow coefficient is calculated as 0.9, as shown in Table 1 below, a theoretical design is possible regardless of the outer diameter of the nozzle body 64 of the introduction nozzle 25 and the inner diameter of the straight pipe portion 22 of the cheese pipe 24. .

Figure 2017042710
Figure 2017042710

以下の表2のとおり、口径40A(上記とは配管径の異なる吸引混合装置21)の場合、流出係数を0.9として計算すると理論通りの設計が可能であった。ノズル本体64の外径の違いによる流出係数の変化はなく、直管部22の内径が同一の場合は、同じ流出係数を使うことができ、ノズル本体64の外径に関係ないことがわかった。   As shown in Table 2 below, in the case of a bore 40A (a suction mixing device 21 having a different pipe diameter from the above), a theoretical design was possible when the outflow coefficient was calculated as 0.9. There was no change in the outflow coefficient due to the difference in the outer diameter of the nozzle body 64, and when the straight pipe portion 22 had the same inner diameter, the same outflow coefficient could be used, and it was found that it was not related to the outer diameter of the nozzle body 64. .
