<P>PROBLEM TO BE SOLVED: To provide an apparatus for manufacturing a hollow porous membrane that allows a discharge temperature of a film-forming resin solution and an atmospheric dew point of a free-running portion to be freely set to enable membrane structure control with a high degree of freedom, while preventing dew condensation and water droplet adhesion on a nozzle surface. <P>SOLUTION: The apparatus for manufacturing a hollow porous membrane includes: a container 6 that is equipped with a spinning nozzle 2 for molding and discharging the film-forming resin solution, a first opening 22 into which the film-forming resin solution molded and discharged from the spinning nozzle 2 is introduced, a supply opening 26 into which gas containing moisture is introduced, and a second opening 24 from which the film-forming resin solution brought into contact with the gas containing moisture is led out; a coagulation tank 16 which stores a coagulation liquid 14 and into which the film-forming resin solution brought into contact with the gas is introduced; and a gas suction device 8 provided between the spinning nozzle 2 and the first opening 22 to suck the gas flowing out from the first opening 22. <P>COPYRIGHT: (C)2012,JPO&INPIT |
