  • Publication number: 20170100701
    Abstract: Disclosed is a hollow fiber membrane module. The hollow fiber membrane module includes a housing including a first fluid inlet, a first fluid outlet, a second fluid inlet and a second fluid outlet, and hollow fiber membrane bundles, each hollow fiber membrane bundle including a plurality of hollow fiber membranes, disposed within the housing so that a first fluid flows inside the hollow fiber membranes and a second fluid flows outside the hollow fiber membranes, and each hollow fiber membrane bundle further includes porous tubes having both ends closed and including a plurality of pores formed on the side surfaces thereof. The hollow fiber membrane module removes a region, into which a fluid flowing outside a hollow fiber membrane bundle has difficulty in permeating, thus allowing the fluid to uniformly flow. Therefore, even if hollow flow membranes are highly integrated, performance of the hollow fiber membrane module may be maximized.

  • Publication number: 20160240870
    Abstract: A fluid exchange membrane module includes a case including at least two pairs of fluid inlets and fluid outlets, and a fluid exchange membrane installed within the case and disposed so that a dry fluid flowing between one pair of a fluid inlet and a fluid outlet does not directly contact a high-humidity fluid flowing between another pair of a fluid inlet and a fluid outlet in the operating state of the module. The fluid inlet for the high-humidity fluid includes a diffuser. The fluid exchange membrane module may adiabatically expand a fluid flowing toward one side of a fluid exchange membrane and thus increase the relative humidity of the high-temperature and high-humidity fluid so as to maximize fluid transmission through the fluid exchange membrane, and may decrease the pressure of the fluid so as to uniform pressure distribution of a fluid flow.

  • Publication number: 20160079616
    Abstract: A hollow fiber module is disclosed. The hollow fiber module in various aspects of the present invention may include: a housing, and a hollow fiber bundle mounted in the housing and having a fluid penetration distance ranged from 10 to 200 mm. The fluid penetration distance means the shortest distance from the outmost hollow fiber in a cross-section of the hollow fiber bundle to the hollow fiber existing at the center in the cross-section of the hollow fiber bundle. In accordance with various embodiments of the present invention, the hollow fiber module may maximize the fluid delivery efficiency by improving the flow uniformity of the fluid flowing the outside of the hollow fibers. In addition, the hollow fiber module may minimize the additional usage of the hollow fibers, and thus the cost and the size of the hollow fiber module may be reduced.

  • Publication number: 20150367279
    Abstract: The present invention relates to a hollow fiber membrane and a hollow fiber membrane module including the same, and the hollow fiber membrane is characterized in that any one selected from the group consisting of the inner diameter and the outer diameter of the hollow fiber membrane and a combination thereof is changed. The hollow fiber membrane induces turbulence of a fluid flow at the inside and outside of the hollow fiber membrane and, thus, improves flow uniformity, thereby maximizing performance of the hollow fiber membrane module including the hollow fiber membrane.

  • Patent number: 9136034
    Abstract: The present disclosure relates to a polymer electrolyte membrane having a construction wherein an ionomer is charged in pores of a nanoweb having a high melting point, being insoluble in an organic solvent and having excellent pore characteristics, under optimum conditions. Therefore, an overall thickness of the electrolyte membrane may be reduced, thereby attaining advantages such as decrease in ohmic loss, reduction of material costs, excellent heat resistance, low thickness expansion rate which in turn prevents proton conductivity from being deteriorated over a long term. The polymer electrolyte membrane of the present invention comprises a porous nanoweb having a melting point of 300? or more and being insoluble in an organic solvent of NMP, DMF, DMA, or DMSO at room temperature; and an ionomer which is charged in pores of the porous nanoweb and contains a hydrocarbon material soluble in the organic solvent at room temperature.
