When the above-mentioned device is used to separate liquids, the device is usually set up vertically and operated in consideration of its installation area. Bubbles and permeate generated at the start of operation may accumulate, causing problems such as microorganisms propagating in this stagnant area and contaminating the permeate.
Furthermore, since the permeated liquid extraction nozzle 15 is located on one side of the outer cylinder 12, the flow of the permeated liquid is biased, which may damage the hollow fibrous membrane 11, which has the disadvantage of causing a decrease in the performance of the fluid separation device. .

A plurality of hollow fibrous membranes 1 are stored in the outer cylinder 4 in a state in which they are bundled in parallel around a permeate collection tube 3 having , the permeated liquid collecting pipe 3 and the outer cylinder 4 are fixed to each other with casting resin 5. The inner surface 51 of the casting resin 5 at the upper end is the end of the permeate collection pipe 3, that is, the opening surface 2 of the hole 2 located at the top in FIG.
It is substantially flush with the opening surface 21 in the vicinity of the opening surface 21, and is curved in a concave shape toward the outside of the outer cylinder 4 from the opening surface 21. That is, the casting resin inner surface 51 is formed such that the thickness of the casting resin 5 gradually increases as it approaches the inner wall of the outer cylinder 4 from the central axis P of the permeated liquid collection tube 3. Here, the degree of curvature is not particularly limited, and the difference between the casting resin thickness l 1 near the outer wall of the permeate collection pipe 3 and the casting resin thickness l 2 near the inner wall of the outer cylinder 4 is l If 2 ~ l 1 is even small,
The effects of the present invention can be obtained, and l2 to l1 is usually about 5 to 50 mm, although it varies depending on the length and diameter of the outer cylinder 4. Further, a joint 8 having a liquid supply nozzle 6 and a permeated liquid extraction nozzle 7 is provided at one end of the outer cylinder 4, and a joint 10 having a concentrated liquid extraction nozzle 9 is provided at the other end.
