Arrangement for heat and mass transfer by means of hollow fibers
First Claim
1. Arrangement for heat and/or mass transfer from a minimum of one first liquid to a minimum of one second liquid by means of hollow fibers from spinnable synthetic polymers, comprising a housing having an internal surface, connections on said housing for supply and draining of the liquids, said housing defining a minimum of one additional liquid drain port, a hollow fiber module removably connected to said housing, said hollow fiber module containing open hollow fibers ends embedded in a casting compound bed having an external surface, said casting compound bed is interconnected by a minimum of one essentially rigid supporting element, an intermediate ring defining a minimum of one bore of essentially radial disposition, said intermediate ring is located between said casting compound bed of said hollow fiber ends and said housing, a minimum of two external gaskets arranged at a distance to each other between said intermediate ring and said internal surface of said housing, a minimum of two internal gaskets arranged at a distance to each other between said intermediate ring and said external surface of said casting compound bed, whereby said intermediate ring, said external gaskets and said internal gaskets define between said housing and said hollow fiber module a distributing chamber and a collecting chamber for said liquids, said minimum of one bore of essentially radial disposition of said intermediate ring ends between said external gaskets and said internal gaskets, said minimum of one additional liquid drain port arranged in said housing between said external gaskets.

Abstract
Arrangement for heat and/or mass transfer between a minimum of two liquids, effected by means of hollow fibers, the open ends of which are imbedded in a casting compound and which hollow fibers are located in the form of hollow fiber modules within a housing, wherein an intermediate ring and gaskets are provided between the housing and the casting compound beds of the hollow fiber module. A bore in the housing allows in case of a defective gasket that leaking liquid may drain to the outside, whereby short circuiting between the different liquid chambers of the housing will be prevented. The intermediate ring may be present as lose component or may, also, be fixedly connected to the face plates of the housing or the housing jacket. A plurality of hollow fiber modules may be arranged within a common housing. The hollow fiber module may be surrounded by a perforated supporting tube. The arrangement is particularly suitable for cross-flow filtration.
