Abstract
Membrane cell stack arrangement and method of manufacturing such a membrane cell stack arrangement. The arrangement has a housing (2) having a central axis, and a stack of membrane cells (4), each membrane cell (6) being arranged inside the housing (2) with a major surface (6a) of the membrane cell (6) oriented substantially perpendicular to the central axis. Each membrane cell (6) has a corner recess (12) between each two adjacent sides of at least four sides (10a-d). Sealing compartments (14) are provided by corner recesses (12) of adjacent membrane cells of the stack of membrane cells (4) in co-operation with a part of an inner surface (2a) of the housing (2).
Claims29
A membrane cell stack arrangement, comprising:
- a housing having a central axis and an inner surface,
- a stack of membrane cells, each membrane cell being arranged inside the housing with a major surface of the membrane cell oriented substantially perpendicular to the central axis,
- each membrane cell having a shape with at least four sides, wherein at least one of the sides of the at least four sides provide a flow input to the membrane cell and at least one of the sides of the at least four sides provide a flow output from the membrane cell and the other sides of the at least four sides provide closed side walls of the membrane cell, wherein
- each membrane cell comprises a corner recess between each two adjacent sides of the at least four sides, and the membrane stack arrangement further comprises sealing compartments which are substantially parallel to the central axis of the housing, each sealing compartment being provided by a corner recess of adjacent membrane cells of the stack of membrane cells in co-operation with a part of the inner surface of the housing.
A method of manufacturing a membrane cell stack arrangement,
- comprising the steps of:
- providing a housing having a central axis and an inner surface;
- building a stack of membrane cells,
- each membrane cell having a shape with at least four sides, wherein at least one of the sides of the at least four sides provide a flow input to the membrane cell and at least one of the sides of the at least four sides provide a flow output from the membrane cell and the other sides of the at least four sides provide closed side walls of the membrane cell, wherein each membrane cell comprises a corner recess between each two adjacent sides of the at least four sides, and positioning the stack of membrane cells in the housing, wherein a major surface of each membrane cell is oriented substantially perpendicular to the central axis of the housing,
- thereby providing sealing compartments extending substantially parallel to the central axis, each sealing compartment being formed by corner recesses of adjacent membrane cells of the stack of membrane cells in co-operation with a part of the inner surface of the housing, and an input compartment and an output compartment, each extending substantially parallel to the central axis of the housing, the input compartment and output compartment being formed by the flow inputs and flow outputs, respectively, of adjacent membrane cells of the stack of membrane cells in co-operation with a further part of the inner surface of the housing.
