摘要

PROBLEM TO BE SOLVED: To efficiently remove a solvent, an additive, a polymer particle and the like remaining in the inside of a hollow yarn membrane by turning the inside of the hollow part of the hollow yarn membrane into a pressure reduced zone before the hollow yarn membrane having a min. pore diameter layer on the outside surface of the membrane is modulated and passing a cleaning liquid from the outside surface side of the membrane to the inside surface side of the membrane. ;SOLUTION: The removal of the solvent, the additive, the polymer particle and the like remaining in the inside of the hollow yarn membrane is performed by treating so that the cleaning liquid is passed from the outside surface side of the membrane to the inside surface side of the membrane. As the method for passing the cleaning liquid, a method for passing the cleaning liquid by evacuating the inside of the hollow part is preferable and to turn the inside of the hollow part into the pressure reduced zone, such a suction pump, a gear pump is used. The cleaning device for the hollow yarn membrane is constituted so as concretely to provide a vessel 6 for housing the hollow yarn membrane, a means 5 for supplying the cleaning liquid in the vessel 6, a means 7 for discharging the liquid from the vessel 6, a means 2 for connecting the inside of the hollow part to a pressure adjusting device 4 and the pressure adjusting device 4 such as the suction pump, gear pump.;COPYRIGHT: (C)1999,JPO
