Title:
NITROGEN GENERATOR
Document Type and Number:
Japanese Patent JPH06227803
Kind Code:
A
Abstract:
PURPOSE: To provide a nitrogen generator having high reliability by slowly increasing the pressure on the feed side of raw material compressed air so as not to peel sealing media and a partition material for each gas separation membrane module in relation to the nitrogen generator using the spiral gas separation membrane module utilizing a flat gas separation membrane.
CONSTITUTION: The opening and closing degree of an actuator valve 32 or an electrically-operated valve (32a) is controlled so as not to peel sealing media 8 and a partition material 4 of each gas separation membrane module 35. Thereby, raw material compressed air fed to the gas separation membrane module 35 is made to require ≥1min time for its pressure to attain 5kgf/cm2G.
