【発明の詳細な説明】 〔産業上の利用分野〕 本発明は、選択性透過膜を用いて流体の膜分離処理を
行うスパイラル型膜分離装置に関するものである。Description: TECHNICAL FIELD The present invention relates to a spiral type membrane separation apparatus for performing a membrane separation treatment of a fluid using a selective permeable membrane.
一般にスパイラル型膜分離装置は、内側に透過流体流

パイラル状に巻回されて構成されている。In general, a spiral-type membrane separation device has an opening end of a membrane envelope made of a selective permeable membrane in which a material for a permeated fluid channel is disposed, and is connected to a perforated hollow tube having a hole for inflow of a permeated fluid,
A membrane envelope and a raw fluid flow path material are spirally wound around the perforated hollow tube.

ている。Conventionally, as such a membrane separation device, as shown in FIG. 4, for example, as shown in FIG. 4, a selectively permeable membrane 101 having an asymmetric structure is bent so that its membrane surface side is inward, and a raw fluid flow path material 102 is sandwiched between the membranes. The material group B is formed by placing the material group B on the road material 103, one side of the material group B is communicated with the perforated hollow tube 104, and the adhesive 105 is applied to the remaining three sides. A device wound spirally around a perforated hollow tube 104 is known.

過して分離装置としての性能を低下させてしまう。However, in such a device, the raw fluid flow path 102a corresponding to the membrane portion having no permselectivity, for example, the adhesive portion.
Since the fluid also flows through the portion, the fluid flowing through that portion is not selectively permeated, and passes through the separation device without changing the fluid component, thereby deteriorating the performance as the separation device.
