<p>Provided is a separating membrane element using anti-telescoping plates, which maintain the function of anti-telescoping plates while making it possible to increase the membrane area. The separation membrane element has an upstream anti-telescoping plate (10a) and a downstream anti-telescoping plate (10b). The upstream anti-telescoping plate (10a) is obtained from: a first ring-shaped section (14) on the outside of which a sheath (8) is fitted; a second ring-shaped section (15), the downstream and upstream endfaces of which can engage with the upstream end of the sheath (8) and the downstream end of a seal ring (12) respectively; a third ring-shaped section (16) on the outside of which the seal ring (12) is fitted; and a fourth ring-shaped section (17), the downstream endface of which can engage with the upstream endface of the seal ring (12). The downstream anti-telescoping plate (10b) is obtained from a fifth ring-shaped section (18) on the outside of which the sheath (8) is fitted, and a sixth ring-shaped section (19), the upstream endface of which can engage with the downstream end of the sheath (8).</p> |
