Claims

[Claims for Utility Model Registration] (1) A spiral membrane formed by winding a permeable membrane that partitions a first region forming a flow path for a supply stock solution and a second region forming a flow path for a permeated liquid. A spiral membrane separation device comprising an element installed in a cylindrical pressure vessel, wherein the upper and lower end surfaces of the cylindrical pressure vessel and the spiral membrane element placed vertically are inclined with respect to the horizontal direction. The space between the upper end surface of the membrane element and the upper end surface of the cylindrical pressure vessel is a raw solution introduction chamber, and the space between the lower end surface of the membrane element and the lower end surface of the cylindrical pressure vessel is a concentrated liquid discharge chamber. A permeate discharge chamber is partitioned between the outer circumferential surface of the membrane element and the inner circumferential surface of the cylindrical pressure vessel, and the permeate discharge chamber is partitioned between the raw solution inlet to the raw solution introduction chamber and the permeate discharge chamber from the permeate discharge chamber. A spiral type membrane separation device, characterized in that the upper end surface of the membrane element is arranged so as to dispose the liquid outlet on substantially the same horizontal line, and to diagonally cross a line connecting the raw liquid inlet and the permeated liquid outlet. (2) The spiral membrane separation device according to claim 1 of the utility model registration claim, wherein a liquid drain valve is provided at the lowest part of the permeate discharge chamber and the concentrated liquid discharge chamber. (3) The spiral membrane separation device according to claim 1 or 2 of the utility model registration claim, which is provided with a negative pressure check valve at the top of the raw solution introduction chamber.
