Abstract:
1. A separation membrane module comprising: an upper horizontal partition plate positioned in an upper portion within a module main body so as to form an upper fluid channel; and a lower horizontal partition plate positioned in a lower portion within the module main body so as to form a lower fluid channel, wherein a plurality of vertical outer tubes are fixed between the upper horizontal partition plate and the lower horizontal partition plate, a vertical tubular membrane element is put through each of the outer tubes with a gap, a horizontal tube plate is positioned above the upper horizontal partition plate within the module main body, each of the membrane elements is fixedly suspended to the tube plate, a discharge chamber is positioned above the tube plate within the module main body, the upper fluid channel is positioned between the tube plate and the upper horizontal partition plate, an upper end of the gap between each of the outer tubes and the membrane element put there through is in communication with the upper fluid channel, a lower end thereof is in communication with the lower fluid channel, an upper end opening of each of the membrane elements is open to the discharge chamber, a lower end opening thereof is closed, and a vertical partition plate is positioned in the upper fluid channel so as to form an inlet chamber and an outlet chamber, a fluid inlet through which fluid is introduced into the module main body and is positioned in such a manner as to be in communication with the inlet chamber, a fluid outlet through which the fluid is removed from module main body and is positioned in such a manner as to be in communication with the outlet chamber, and a separated fluid discharge port is positioned in such a manner as to be in communication with the discharge chamber, the fluid inlet and the fluid outlet are positioned between the upper horizontal partition plate and the tube plate, and the module main body includes an open vertical cylindrical body and a lid body which is laid over an upper end of the cylindrical body, the tube plate is positioned between the cylindrical body and the lid body such that the tube plate and the lid body define the discharge chamber, and the discharge chamber is positioned above the inlet chamber and the outlet chamber.
