〔産業上の利用分野〕
本考案は限外濾過、精密濾過によつて流体と流
体中の特定成分とを分離する為に膜分離装置内に
使用されるセラミツクフイルターに関するもので
ある。[Detailed description of the invention] [Field of industrial application] The present invention relates to a ceramic filter used in a membrane separation device to separate a fluid from a specific component in the fluid by ultrafiltration or precision filtration. It is something.
従来、セラミツクフイルターはセラミツク製の
管状分離膜群両端をＯリングや接着剤を介して固
定用管板に固定することによつて集積化されてい
た。
Conventionally, ceramic filters have been integrated by fixing both ends of a group of ceramic tubular separation membranes to a fixing tube plate via O-rings or adhesives.
ところが、斯る従来例の場合、下記の問題点が
ある。 However, in the case of such a conventional example, there are the following problems.
固定用管板に管状分離膜を嵌合させる嵌合口
若しくは連通口を開口する際、嵌合口や連通口
相互を近接して開口するのが難かしく、その数
には制限がある為、管状分離膜群をコンパクト
に集積できず、膜分離装置内に装備するに際し
て単位容積あたりの膜面積が大きくできず、濾
過効率の向上が望めない。 When opening the fitting ports or communication ports for fitting the tubular separation membrane to the fixing tube plate, it is difficult to open the fitting ports or communication ports close to each other, and there is a limit to the number of ports, so tubular separation Membranes cannot be assembled compactly, and the membrane area per unit volume cannot be increased when installed in a membrane separation device, making it impossible to expect improvement in filtration efficiency.
管状分離膜個々を固定用管板に嵌合固定する
作業や内部流路と連通孔とを合致させる位置合
わせ作業が面倒である。 The work of fitting and fixing each tubular separation membrane to the fixing tube plate and the positioning work of matching the internal channels and the communication holes are troublesome.
そこで、今日、上記する従来例を解決する為に
特開昭56−129020号公報のものが開発された。 Therefore, in order to solve the above-mentioned conventional problem, the one disclosed in Japanese Patent Application Laid-open No. 129020/1983 has been developed.

１００内の少なくとも一辺の隔壁１０１′を共有
する貫通孔１０１，１０１相互において一方の貫
通孔１０１は一端を、他方の貫通孔１０１は他端
を夫々封止して一方を原液流路１０２、他方を透
過液流路１０３としたものである。 As shown in FIG. 5, this improved example is a porous honeycomb structure 100 having a large membrane area per unit volume and a large number of through holes 101 that can be easily modularized. Regarding the holes 101 and 101, one end of one through hole 101 and the other end of the other through hole 101 are sealed, respectively, so that one end becomes a stock solution flow path 102 and the other end becomes a permeate flow path 103.
しかし乍ら、斯る改良例の場合、原液流路１０
２は一端、即ち出口端を封止した構造となるか

濾過効率の急激な低下を招くばかりでなく、逆流
によつてゲル層の除去を実施する際、原液流路１
０２は一端を閉口している為、その封止端近傍の
隔壁面に付着したゲル層の除去が確実ではない問
題点を有する。 However, in the case of such an improved example, the stock solution flow path 10
2 has a structure in which one end, that is, the outlet end, is sealed, so a cross-flow filtration method cannot be adopted and a total filtration method is used. Therefore, components whose permeation is restricted gel, adhere, and grow on the membrane surface and rapidly The permeation flux is attenuated to
Not only will this result in a rapid decrease in filtration efficiency, but also when removing the gel layer by backflow,
Since 02 has one end closed, there is a problem in that the gel layer attached to the partition surface near the sealed end cannot be removed reliably.

Our goal is to provide ceramic filters that can be expected.
