Description

本発明は平板状の膜エレメントを備えた膜カセットとこれを有する膜ユニットに関する。   The present invention relates to a membrane cassette provided with a flat membrane element and a membrane unit having the same.

下水処理や産業排水処理において固液分離手段として適用されている膜分離装置は、排水に含まれる汚濁物質を生物処理若しくは凝集処理した後に固形物質と水成分とに固液分離する装置であって、生物処理槽内若しくは凝集処理槽内の液相に浸漬される。   A membrane separation device applied as a solid-liquid separation means in sewage treatment or industrial wastewater treatment is a device that solid-liquid separates solid substances and water components after biologically treating or coagulating the pollutants contained in the wastewater. It is immersed in the liquid phase in the biological treatment tank or the coagulation treatment tank.

膜分離装置としては、例えば特許文献１に開示された膜カセットが知られている。この膜カセットは平板状の複数の膜エレメントが枠体内に所定間隔で配置される。特に、この膜エレメントは前記枠体から引き出し可能に当該枠体の案内溝に装着される。   As a membrane separator, for example, a membrane cassette disclosed in Patent Document 1 is known. In this membrane cassette, a plurality of flat membrane elements are arranged in the frame at predetermined intervals. In particular, the membrane element is mounted in a guide groove of the frame so that it can be pulled out from the frame.

しかしながら、特許文献１の膜カセットは、個々の膜エレメントが膜カセットの集水管に対してフレキシブル管を介してコネクタによって接続されるので、メンテナンス時に膜エレメントを装着脱する際、フレキシブル管やコネクタの脱着作業に多くの時間を要する。特に、膜カセットの設置規模によっては膜エレメントの装着枚数は数千から数万となるので維持管理に相当な手間を要する。また、膜エレメントの着脱作業時にはフィルタ本体を損傷または破損させないように慎重な取り扱いを要する。   However, in the membrane cassette of Patent Document 1, each membrane element is connected to the water collecting tube of the membrane cassette by a connector via a flexible tube. Desorption work takes a lot of time. In particular, depending on the installation scale of the membrane cassette, the number of membrane elements to be installed can be from several thousands to several tens of thousands, so considerable maintenance is required. Further, careful handling is required so that the filter main body is not damaged or broken when the membrane element is attached or detached.

そこで、膜カセットと集水管とを接続するフレキシブル管を不要とする膜カセットとして、特許文献２に開示された膜カセットが知られている。この膜カセットの膜エレメントは、平板状のセラミックフィルタと、このセラミックフィルタの両端部に具備される集水部とからなる。そして、この膜エレメントの集水管部並びに集水部がラック内に係止されることにより、複数の膜エレメントが当該ラック内に支持される。   Then, the membrane cassette disclosed by patent document 2 is known as a membrane cassette which does not require the flexible pipe | tube which connects a membrane cassette and a water collection pipe. The membrane element of the membrane cassette includes a flat ceramic filter and water collecting portions provided at both ends of the ceramic filter. And the water collecting pipe part and water collecting part of this membrane element are latched in a rack, and a plurality of membrane elements are supported in the rack.

特開２００９−１４８７４３号公報JP 2009-148743 A 米国特許出願公開第２００９／０２３６２９５号明細書US Patent Application Publication No. 2009/0236295

特許文献２仕様の膜カセットは、膜エレメントと集水管とを接続するフレキシブル管やこれに付属する部材などの脱着作業が不要となるので、特許文献１仕様の膜カセットと比べて組立作業性やメンテナンス性が向上する。   Since the membrane cassette of the specification of Patent Document 2 does not require the detachment work of the flexible pipe connecting the membrane element and the water collecting pipe and the members attached thereto, the assembly workability and the membrane cassette of Patent Document 1 specification are reduced. Maintainability is improved.

しかしながら、複数の膜カセットを水槽内に配置して廃水処理に供する場合に、個々の膜カセットから処理水を取り出す取水配管が必要となる。この取水配管は複数の膜カセットを水槽内に設置する前または設置した後に個々の膜カセットに取り付けられる。例えば、特許文献２の膜カセットを水槽内に積層させる場合、個々の膜カセットの集水管に別途の配管を介して取水配管が接続される。   However, when a plurality of membrane cassettes are arranged in a water tank and used for wastewater treatment, a water intake pipe for extracting treated water from each membrane cassette is required. This intake pipe is attached to each membrane cassette before or after installing a plurality of membrane cassettes in the water tank. For example, when the membrane cassettes of Patent Document 2 are stacked in a water tank, intake pipes are connected to the water collecting pipes of the individual membrane cassettes via separate pipes.

以上のことから、特許文献２仕様の膜カセットは、単体としての取り扱い性が向上しているが、この膜カセットを複数備えて膜ユニットを構成した場合に膜ユニットの組立や膜エレメントの点検や交換の際の作業性が効率的なものではない。   From the above, the membrane cassette of the specification of Patent Document 2 has improved handling as a single unit. However, when a membrane unit is configured with a plurality of membrane cassettes, the assembly of the membrane unit, the inspection of the membrane element, The workability at the time of replacement is not efficient.

本発明は、上記の事情に鑑み、膜エレメントを備えた膜カセットをユニット化した際のメンテナンス性の向上を図ることを課題とする。   This invention makes it a subject to aim at the improvement of the maintainability at the time of unitizing the membrane cassette provided with the membrane element in view of said situation.

（膜ユニット１１の組立手順例）
図８を参照しながら膜ユニット１１の組立手順の一例について説明する。 (Example of assembly procedure of membrane unit 11)
An example of the assembly procedure of the membrane unit 11 will be described with reference to FIG.

先ず、膜カセット１のサイドカバー５の下縁部，上縁部における取り付け孔５１に図示省略のずれ止めピンが挿通された状態で二つの膜カセット１が上下に仮配置される。そして、前記ズレ止めピンが外された取り付け孔５１に締結具が取り付けられることにより、膜カセット１が上下に積層される。以上の手順を繰り返すことにより、同図に例示されたように膜カセット１を１０段積層させたカセット積層部１２が完成する。   First, the two membrane cassettes 1 are temporarily arranged up and down in a state in which a non-illustration stopper pin is inserted into the mounting holes 51 in the lower edge portion and the upper edge portion of the side cover 5 of the membrane cassette 1. And a membrane cassette 1 is laminated | stacked up and down by attaching a fastener to the attachment hole 51 from which the said slip prevention pin was removed. By repeating the above procedure, a cassette stacking section 12 is completed in which ten layers of film cassettes 1 are stacked as illustrated in FIG.

カセット積層部１２は最上位の膜カセット１の把持部５２に吊り上げ具が連結されて吊り上げられた状態で水槽内に搬入される。次いで、このカセット積層部１２は最下位の膜カセット１が散気架台１３２の位置決めピンに位置決めされた状態で散気架台１３２に固定される。そして、最上位の膜カセット１のフランジ部１５に対して移送管１６のフランジ部１７が液密的に接続される。   The cassette stacking unit 12 is carried into the water tank in a state of being lifted by a lifting tool connected to the grip 52 of the uppermost membrane cassette 1. Next, the cassette stacking unit 12 is fixed to the diffuser mount 132 in a state where the lowest film cassette 1 is positioned on the positioning pin of the diffuser mount 132. Then, the flange portion 17 of the transfer pipe 16 is liquid-tightly connected to the flange portion 15 of the uppermost membrane cassette 1.

以上のようにカセット積層部１２は同図に示したように水槽内において二列に配置された状態で散気部１３に固定されて膜ユニット１１が完成する。   As described above, the cassette stacking unit 12 is fixed to the air diffusion unit 13 in a state where it is arranged in two rows in the water tank as shown in FIG.

膜ユニット１１のメンテナンスの際に膜エレメント２の交換を行う場合には、先ず、カセット積層部１２のフランジ部１５から移送管１６のフランジ部１７が取り外される。次いで、カセット積層部１２の最上位における膜カセット１の双方のサイドカバー５に把持部５２が取り付けられ、さらに、この把持部５２に吊り上げ具が連結された状態で散気架台１３２におけるカセット積層部１２の固定が解除される。次いで、カセット積層部１２は前記吊り上げ具によって吊り上げられることにより水槽内から搬出される。この搬出されたカセット積層部１２は最上位の膜カセット１から順次切り離されることにより全ての膜カセット１が単独に分離される。   When the membrane element 2 is replaced during the maintenance of the membrane unit 11, first, the flange portion 17 of the transfer pipe 16 is removed from the flange portion 15 of the cassette stacking portion 12. Next, the gripping portions 52 are attached to both side covers 5 of the membrane cassette 1 at the uppermost position of the cassette stacking portion 12, and the cassette stacking portion in the diffusion rack 132 is connected to the gripping portion 52 with a lifting tool. 12 is released. Next, the cassette stacking unit 12 is carried out of the water tank by being lifted by the lifting tool. The unloaded cassette stacking section 12 is sequentially separated from the uppermost film cassette 1 so that all the film cassettes 1 are separated independently.

そして、取り付け本体部７１から処理水集合部４が取り外され、さらに、膜カセット１の取り付け部材７並びに上押え部６における上方の締結具が取り外された後に、取り付け部材７並びに上押え部６をサイドカバー５の外側に回動させると、膜エレメント２の交換が可能となる。また、膜ユニット１１の施工時、水槽内に被処理水が無い場合、水槽内での膜ユニット１１のメンテナンス作業が可能となる。   Then, after the treated water collecting portion 4 is removed from the attachment main body portion 71 and the upper fasteners in the attachment member 7 and the upper presser portion 6 of the membrane cassette 1 are further removed, the attachment member 7 and the upper presser portion 6 are removed. When it is turned to the outside of the side cover 5, the membrane element 2 can be exchanged. In addition, when the membrane unit 11 is constructed, if there is no water to be treated in the water tank, maintenance work of the membrane unit 11 in the water tank becomes possible.

尚、上記の説明は上押え部６及び取り付け部材７がサイドカバー５に軸着される態様となっているが、本発明のサイドカバー５に対する上押え部６及び取り付け部材７の取り付けの態様は本態様に限定されるものではない。例えば、上押え部６をサイドカバー５の外側に回動させ、そして、処理水集合部４を取り外すことで膜エレメント２の設置や交換が行える場合には、サイドカバー５に対して上押え部６のみ軸着される態様を採ってもよい。   In the above description, the upper presser portion 6 and the attachment member 7 are mounted on the side cover 5, but the upper presser portion 6 and the attachment member 7 are attached to the side cover 5 according to the present invention. It is not limited to this mode. For example, when the membrane element 2 can be installed or replaced by rotating the upper pressing portion 6 to the outside of the side cover 5 and removing the treated water collecting portion 4, the upper pressing portion with respect to the side cover 5 is used. Alternatively, only 6 may be attached.

（本実施形態の効果）
以上の膜ユニット１１によれば、膜カセット１を積層させる過程で、一方の膜カセット１の下端配管部４３と当該一方の膜カセット１の直下に位置する他方の膜カセット１の上端配管部４２とを直接連結させることができる。 (Effect of this embodiment)
According to the membrane unit 11 described above, in the process of stacking the membrane cassettes 1, the lower end piping portion 43 of one membrane cassette 1 and the upper end piping portion 42 of the other membrane cassette 1 positioned immediately below the one membrane cassette 1. Can be directly connected.

したがって、膜カセット１を複数備えて膜ユニット１１を構成させる場合、フレキシブル管が不要となり、膜カセット１の相互接続が簡略化するので、膜ユニット１１の組立や膜エレメントの点検や交換の際の作業性が著しく向上する。   Therefore, when the membrane unit 11 is configured by including a plurality of membrane cassettes 1, a flexible pipe is not necessary, and the interconnection of the membrane cassette 1 is simplified. Therefore, when the membrane unit 11 is assembled, the membrane element is inspected or replaced. Workability is significantly improved.
