MANUFACTURING APPARATUS FOR HOLLOW POROUS FILM, AND TREATMENT CONTAINER FOR USE IN THE MANUFACTURING APPARATUS

摘要

PROBLEM TO BE SOLVED: To provide a treatment container for preventing the contact in a treatment container between a membrane forming raw liquid and a condensate liquid at the time of manufacturing a hollow porous film.SOLUTION: A treatment container for use in a manufacturing apparatus for a hollow porous film comprises: an introduction port for introducing a membrane forming raw liquid containing a film forming resin of the hollow porous film into the treatment container; a gas supply port for supplying a gas containing a non-solvent component of a film forming resin into the treatment container; a derivation port for deriving the membrane forming raw liquid introduced into the treatment container, to the outside of the treatment container; an exhaust port for discharging the condensate liquid of the non-solvent component from the treatment container; and a space for bringing the membrane forming raw liquid and a gas containing the non-solvent component of the film forming resin into contact with each other.
