MEMBRANE MODULE FOR HYDROGEN PURIFICATION

摘要

PURPOSE: A hydrogen refining separating membrane module is provided to block the risk of internal hydrogen leakage and separating membrane damage due to the introduction of external oxygen in case of being operated at high temperatures by using inner sealant and outer sealant. CONSTITUTION: A hydrogen refining separating membrane module(1) includes a hydrogen separating membrane(10), a porous support(20), a lower flange(40), an upper flange(30), inner sealant(50), and outer sealant(55). The lower flange includes a first loading part(41), a supporting protrusion part, at least one hydrogen penetrating holes, a second loading part(42). The hydrogen separating membrane and the porous support are loaded on the first loading part. The supporting protrusion part is arranged at the first loading part and forms a hydrogen discharging path to support the porous support. The hydrogen penetrating hole is penetrated at the first loading part. The second loading part is formed at the outer side of the first loading part. The upper flange includes at least one penetration holes and secures air tightness in case of being fastened with the lower flange. The inner sealant prevents the leakage of gas by being arranged at the first loading part. The outer sealant prevents the leakage of gas by being arranged at the second loading part.
