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.
