Description

本発明は、液体に溶解しているイオンや分子或いは混入している不純物を液体から取り除く膜エレメントを収容する膜モジュール用ベッセルに関する。   The present invention relates to a membrane module vessel that accommodates a membrane element that removes ions or molecules dissolved in a liquid or mixed impurities from a liquid.

液体に溶解しているイオンや分子或いは混入している不純物を液体から取り除く手段として、液体は透過させるが、液体内に溶解しているイオンや分子或いは混入している不純物を透過させない性質を持つ半透膜からなるスパイラル構造の膜エレメントをベッセルに収容した膜モジュールが使用されている。   As a means of removing ions, molecules or mixed impurities dissolved in the liquid from the liquid, it allows the liquid to pass through, but does not allow the ions, molecules or mixed impurities dissolved in the liquid to pass through. A membrane module in which a spiral-structured membrane element made of a semipermeable membrane is accommodated in a vessel is used.

この膜モジュールは、一般に、ベッセルの一端側に有する被処理液供給口部から被処理液を機械的圧力を加えて供給して、膜エレメントの一端側へ送り込み、膜エレメントを透過した処理液を膜エレメントの軸心部に配置した処理液収集管に収集してベッセルの他端側に有する処理液導出口部から導出し、また、膜エレメントを透過されなかった濃縮液をベッセルに有する濃縮液排出口部から排出する構造となっている。   In general, this membrane module supplies a liquid to be processed from a supply port of a liquid to be processed on one end side of the vessel by applying mechanical pressure, sends the liquid to one end side of the membrane element, and transmits the processing liquid that has passed through the membrane element. Concentrated liquid that is collected in a processing liquid collecting tube arranged at the axial center of the membrane element and is led out from the processing liquid outlet port that is provided on the other end of the vessel, and that contains the concentrated liquid that has not been permeated through the membrane element. It is structured to discharge from the discharge port.

かかる膜モジュールにおける膜エレメントを収容するベッセルとして、従来、ベッセルの一端側に有する被処理液供給口部や濃縮液排出口部がベッセルの一方の端部を閉鎖する閉鎖蓋に設けられ、ベッセルの軸方向と同方向に開口する直管で構成されたものや、濃縮液排出口部がベッセルの筒状体に設けられているものや、また、処理液導出口部がベッセルの端部を閉鎖する閉鎖蓋に、前記処理液収集管と同軸上に設けられ、処理液導出口部と処理液収集管とがアダプタにより接続された構造のものが知られている（例えば、特許文献１参照。）。
特開２００３−２５１１５４号公報 As a vessel for accommodating a membrane element in such a membrane module, conventionally, a liquid supply port portion to be processed and a concentrate discharge port portion provided on one end side of the vessel are provided on a closing lid that closes one end portion of the vessel. Consists of a straight pipe that opens in the same direction as the axial direction, a concentrate discharge port provided in the cylindrical body of the vessel, and a processing solution outlet closes the end of the vessel A closed lid is provided coaxially with the processing liquid collection tube, and a structure in which the processing liquid outlet port and the processing liquid collection pipe are connected by an adapter is known (for example, see Patent Document 1). ).
JP 2003-251154 A

しかしながら、このような構造のベッセルでは、ベッセルの端部を閉鎖する閉鎖蓋に設けられている被処理液供給口部や濃縮液排出口部は、ベッセルの軸方向と同方向に開口する直管で構成されているので、かかる構造のベッセルをもつ膜モジュール同士を接続する場合、直管同士を直結することができず、膜モジュール同士の接続には所要の長さの接続用配管が別途必要になり、工数が増え、コストアップするといった問題があった。   However, in the vessel having such a structure, the liquid supply inlet and the concentrate outlet provided in the closing lid for closing the end of the vessel are straight pipes that open in the same direction as the axial direction of the vessel. Therefore, when connecting membrane modules having vessels with such a structure, straight pipes cannot be connected directly, and a connection pipe of the required length is required for connecting membrane modules. As a result, the man-hours increased and the cost increased.

また、ベッセルを、筒状体に直管で構成された被処理液供給口部や濃縮液排出口部を突出させて設けた構造とした場合は、かかる構造のベッセルをもつ膜モジュール同士を接続する場合、直管同士を直結することができるが、膜モジュール同士の接続は容易となるが、直管同士の接続，分離のために膜モジュールの側面に広いメンテナンススペースが必要となるといった問題があった。   In addition, when the vessel has a structure in which the liquid supply port to be processed and the concentrated liquid discharge port configured as straight pipes are provided on the cylindrical body, the membrane modules having the vessel having such a structure are connected to each other. In this case, straight pipes can be directly connected to each other, but the membrane modules can be easily connected to each other, but there is a problem that a large maintenance space is required on the side of the membrane module for connecting and separating the straight pipes. there were.

また、被処理液供給口部からベッセル内へ被処理液を供給することによる膜エレメントが受ける処理液導出口部側に作用する液圧を、膜エレメントの軸心に配置した処理液収集管を処理液導出口部に接続するアダプタが受ける構造となっているので、アダプタは液圧を受けるため耐久性のある取り付けが必要となり、その取り付けスペースが大となり、ベッセルの長さが長くなり、そのため、膜モジュールの設置に広いスペースが必要になるといった問題があった。   In addition, a processing liquid collection tube is arranged in which the liquid pressure acting on the processing liquid outlet port received by the membrane element by supplying the processing liquid into the vessel from the processing liquid supply port is arranged at the axis of the membrane element. Since the adapter connected to the processing liquid outlet port is configured to receive the adapter, the adapter is subjected to fluid pressure, so it must be installed with durability, and its installation space is increased, and the length of the vessel is increased. There is a problem that a large space is required for installing the membrane module.

本発明の目的は、膜モジュール同士の接続を小スペースで容易に行えるようにした膜モジュール用ベッセルを提供することにある。
本発明の他の目的は、全体の小型化を可能にし、膜モジュールの設置の小スペース化が図れるようにした膜モジュール用ベッセルを提供することにある。 An object of the present invention is to provide a membrane module vessel in which membrane modules can be easily connected in a small space.

By arranging a plurality of membrane modules in parallel and connecting the to-be-processed liquid supply port and the concentrated liquid discharge port facing each other directly using a connecting device or using a short connection pipe, Compared to the configuration of connecting the liquid supply port to be processed and the concentrated liquid discharge port configured by a straight pipe that opens in the same direction as the axial direction of the conventional vessel, it can be connected much more easily, Connect in a small space.

また、配置された複数の膜モジュールは、相互の側面間でのメンテナンススペースを必要としないので、膜モジュール相互の側面の間隔を狭くして配置できるので、膜モジュールの設置の小スペース化を図ることができる。   In addition, since the plurality of arranged membrane modules do not require a maintenance space between the side surfaces, the space between the side surfaces of the membrane modules can be reduced, so that the space for installing the membrane modules can be reduced. be able to.

請求項２に記載の発明は、請求項１に記載の、前記筒状体の両側に取り付けられた閉鎖蓋は、それぞれ筒状体に回転自在に取り付けられていることを特徴とする。   The invention according to claim 2 is characterized in that the closing lids attached to both sides of the cylindrical body according to claim 1 are rotatably attached to the cylindrical body, respectively.

かかる構成から、閉鎖蓋を回転させ前記被処理液供給口部や濃縮液排出口部の向きを変えることにより、膜モジュールの接続方向（配置方向）を設置スペースに応じて任意に求めることができる。   With this configuration, the connection direction (arrangement direction) of the membrane module can be arbitrarily determined according to the installation space by rotating the closing lid and changing the direction of the liquid supply port to be processed and the concentrate discharge port. .

請求項３に記載の発明は、請求項１に記載の、前記一方の閉鎖蓋に設けられた前記被処理液供給口部は、１８０度開口位置を異にする一対の供給口を備えており、また、前記他方の閉鎖蓋に設けられた濃縮液排出口部も、１８０度開口位置を異にする一対の排出口を備えており、更に、前記被処理液供給口部と濃縮液排出口部は同方向に開口していることを特徴とする。   According to a third aspect of the present invention, in the first aspect, the liquid supply port portion to be treated provided on the one closing lid includes a pair of supply ports having different opening positions by 180 degrees.

かかる構成から、被処理液供給口部からベッセル内へ被処理液を供給することによる膜エレメントが受ける処理液導出口部側に作用する液圧を、処理液導出口部と濃縮液排出口部を設けた閉鎖蓋の外周端面をもって構成される当接面が膜エレメントの外周端部に有する膜押さえ端部と当接して支持するので、膜エレメントの軸心に配置した処理液収集管を処理液導出口部に接続するアダプタに、従来のような耐久性のある取り付けが必要なくなり、その分、その取り付けスペースを小さくすることが可能となり、ベッセルの長さを短くすることができるので、膜モジュールの設置スペースを小さくすることができる。   With this configuration, the liquid pressure acting on the processing liquid outlet port received by the membrane element by supplying the liquid to be processed into the vessel from the processing liquid supply port is reduced to the processing liquid outlet and the concentrated liquid outlet. Since the abutment surface constituted by the outer peripheral end surface of the closure lid provided with the abutment is in contact with and supports the membrane pressing end portion provided at the outer peripheral end portion of the membrane element, the processing liquid collecting tube arranged at the axial center of the membrane element is processed.

このように構成された複数の膜モジュール１を直列に接続する場合、図２に示すように、一方の膜モジュール１のベッセル２に設けられている被処理液供給口部１７と他方の膜モジュール１のベッセル２に設けられている濃縮液排出口部１９を向かい合わせにして複数の膜モジュール１を平行に配置する。そして、向かい合わせとなっている被処理液供給口部１７と濃縮液排出口部１９を接続器具（図示省略）を用いて直結或いは短い接続用配管（図示省略）を使って接続する。   When a plurality of membrane modules 1 configured in this way are connected in series, as shown in FIG. 2, the liquid supply port 17 to be processed provided in the vessel 2 of one membrane module 1 and the other membrane module A plurality of membrane modules 1 are arranged in parallel with the concentrate discharge ports 19 provided in one vessel 2 facing each other. And the to-be-processed liquid supply port part 17 and the concentrate discharge | emission port part 19 which are facing each other are connected directly or using short connection piping (illustration omitted) using a connection tool (illustration abbreviation).

このように接続することにより、従来のベッセルの軸方向と同方向に開口する直管で構成されている被処理液供給口部と濃縮液排出口部を接続する構成に比べ、遙かに簡単に接続することができるとともに、小さいスペースで接続できる。また、配置された複数の膜モジュール１は、相互の側面間でのメンテナンススペースを必要としないので、膜モジュール１相互の側面の間隔を狭くして配置できるので、膜モジュール１の設置の小スペース化を図ることができる。   By connecting in this way, it is much simpler than the configuration in which the liquid supply port to be processed and the concentrated liquid discharge port that are configured by a straight pipe that opens in the same direction as the axial direction of a conventional vessel are connected. And can be connected in a small space. Further, since the plurality of arranged membrane modules 1 do not require a maintenance space between the side surfaces, the space between the side surfaces of the membrane modules 1 can be reduced, so that a small space for installing the membrane module 1 is provided. Can be achieved.

また、本例では、前記筒状体１０の両側に取り付けられた閉鎖蓋１１，１２は、それぞれ筒状体１０に回転自在に取り付けられているので、閉鎖蓋１１，１２をそれぞれ回転させ、前記被処理液供給口部１７や濃縮液排出口部１９の向きを変えることにより、膜モジュール１の接続に際し、膜モジュール１の接続方向（配置方向）を設置スペースに応じて任意に求めることができる。   Moreover, in this example, since the closure lids 11 and 12 attached to both sides of the cylindrical body 10 are rotatably attached to the cylindrical body 10, respectively, the closure lids 11 and 12 are rotated, respectively. By changing the orientation of the liquid supply inlet 17 and the concentrate outlet 19, the connection direction (arrangement direction) of the membrane module 1 can be arbitrarily determined according to the installation space when connecting the membrane module 1. .

また、本例では、処理液導出側に取り付けられる閉鎖蓋１２の外周端面が、筒状体１０内に収容されている膜エレメント３の処理液導出側の外周端部に有する押さえ端部７に当接して支持する支持面２０となっているので、被処理液供給口部１７からベッセル２内へ被処理液を供給することによる膜エレメント３が受ける処理液導出口部１８側に作用する液圧を、閉鎖蓋１２の支持面２０が膜エレメント３の外周端部に有する押さえ端部７に当接して支持するので、膜エレメント３の軸心部に配置した処理液収集管５を処理液導出口部１８に接続するアダプタ９に、従来のような耐久性のある取り付けが必要なくなり、その分、その取り付けスペースを小さくすることが可能となり、ベッセル２の長さを短くすることができるので、膜モジュール１の設置スペースを小さくすることができる。   Further, in this example, the outer peripheral end surface of the closing lid 12 attached to the treatment liquid outlet side is formed on the holding end 7 that the membrane element 3 accommodated in the cylindrical body 10 has at the outer peripheral end portion on the treatment liquid outlet side. Since the support surface 20 is in contact with and supported, the liquid acting on the processing liquid outlet port 18 side received by the membrane element 3 by supplying the liquid to be processed into the vessel 2 from the liquid supply port 17 to be processed. Since the pressure is supported by the supporting surface 20 of the closure lid 12 in contact with the holding end 7 of the outer peripheral end of the membrane element 3, the treatment liquid collecting tube 5 disposed at the axial center of the membrane element 3 is treated with the treatment liquid. Since the adapter 9 connected to the outlet 18 is not required to have a durable attachment as in the prior art, the attachment space can be reduced accordingly, and the length of the vessel 2 can be shortened. , Membrane mod It is possible to reduce the installation space of Le 1.
