Abstract
ABSTRACT OF THE DISCLOSURE
A hollow-fiber permeability apparatus includes a housing having a permeating region, a bundle of permeable-wall hollow fibers in the permeating region, means for supplying a first fluid flowing between the exteriors of the fibers, another means for passing a second fluid through the interiors of fibers such that materials selectively permeate through the walls of the fibers, and an enlarged cross-section portion to define at least one compartment between the bundle and a wall of the housing and having an inlet opening for introducing the first fluid into the housing, the permeating region having a flattened cross-section in the direction substantially perpendicular to the lengthwise direction of the fibers, and the enlarged cross-section portion being formed at least along substantially the whole lengths of the longer side of the cross section of the permeating region.

Claims (11)
1. In a hollow fiber permeability apparatus comprising a housing having a permeating region, a bundle of permeable-wall hollow fibers disposed in parallel in said permeating region, means for supplying a first fluid flowing between the exteriors of said fibers, and another means for passing a second fluid through the interiors of fibers such that materials selectively permeate through the walls of said fibers, said permeating region having a flattened cross-section in the direction substantially perpendicular to the lengthwise direction of said fibers, first and second enlarged cross-section portions molded integrally with said housing at the opposite ends thereof, each of said enlarged cross-section portions defining compartments between said bundle and a wall of said housing, an inlet opening defined by said first enlarged cross-section portion for introducing said first fluid into said housing, and an outlet opening defined by said second enlarged cross-section portion for removal of said first fluid from said housing, tubular elements molded integrally with said housing and communicating with said inlet opening and said outlet opening for delivering said first fluid and for removal of said first fluid, the improvement wherein each of said enlarged cross-section portions are formed along substan-tially the whole lengths of both longer sides of the flattened cross-section of said permeating region and along at least one shorter side of said flattened cross-section, said tubular elements being formed adjacent said shorter sides of said flattened cross-section, and said tubular elements defining pass-ages disposed substantially in parallel with said longer sides of said flattened cross-section, at least the major portion of the bundle surfaces positioned immediately opposite the interior walls defined by said first enlarged cross-section portion being exposed to said first fluid exiting from the passage of the tubular element delivering the first fluid whereby the first fluid has unimpeded entry between the fibers from said first enlarged cross-section portion, said first enlarged cross-section portion comprising separate portions including two parts formed on opposite longer sides of said hollow fiber bundle, the volume ratio of one said part to the other said part ranging from 0.2 to 0.8, said second enlarged cross-section portion comprising separate portions including two parts formed on opposite sides of said hollow fiber bundle, the volume ratio of one said part of the other said part ranging from 0.2 to 0.8, said one part of said first enlarged cross-section portion being located at the same side of the permeating region as the other part of said second enlarged cross-section portion with the other part of the first cross-section portion being located at the same side of the permeating region as the first part of said second enlarged cross-section portion, said first fluid comprising a liquid, the volume ratio of said hollow fibers swelled with said liquid relative to the volume of said permeating region to be charged with said hollow fibers being in the range of 25 to 60 percent, and wherein said means for passing said second fluid through the interiors of said fibers includes a first cap with inlet means for said second fluid, said first cap being mounted at one end of said housing, and a second cap with outlet means for said second fluid, said second cap being mounted at the other end of said housing.
2. A hollow fiber permeability apparatus according to Claim 1, in which said enlarged cross-section portions are formed along the whole circumferential surface of said permeating region.
3. A hollow fiber permeability apparatus according to Claim 1, in which said one part and said other part are different from each other in length along the lengthwise direction of said hollow fibers.
4. A hollow fiber permeability apparatus according to Claim 1, in which said one part and said other part are equal in length along the lengthwise direction of said hollow fibers, and are different from each other in width substantially perpendicular to the lengthwise direction of said hollow fibers.
5. A hollow fiber permeability apparatus according to Claim 1, in which the tubular element for delivering said first fluid is formed toward the shorter side of the cross-section of said permeating region on the one part of said first enlarged cross-section portion having larger volume, said tubular element being offset relative to the permeating region whereby it is substantially in parallel with the length of said one part of said first enlarged cross-section portion.
6. A hollow fiber permeability apparatus according to Claim 1, in which said tubular element for delivering said first fluid is formed toward the shorter side of the cross-section of said permeating region on the other part of said first enlarged cross-section portion having smaller volume, said tubular element being offset relative to the permeating region whereby it is substantially in parallel with the length of said other part of said first enlarged cross-section portion.
7. A hollow fiber permeability apparatus according to Claim 1, in which the two parts of said second enlarged cross-section portion are different from each other in length along the lengthwise direction of said hollow fibers.
8. A hollow fiber permeability apparatus according to Claim 1, in which two parts of said second enlarged cross-section portion are equal in length along the lengthwise direction of said hollow fibers and are different from each other in width substantially perpendicular to the lengthwise direction of said hollow fibers.
9. A hollow fiber permeability apparatus according to Claim 1, in which the tubular outlet for removal of said first fluid is formed toward the shorter side of the cross-section of said permeating region on the one part of said second enlarged cross-section portion having larger volume, said tubular outlet being offset relative to the permeating region whereby it is substantially in parallel with the length of said one part of said second enlarged cross-section portion.
10. A hollow fiber permeability apparatus according to Claim 1, in which the tubular outlet for removal of said first fluid is formed toward the shorter side of the cross-section of said permeating region on the other part of said second enlarged cross-section portion having smaller volume, said tubular outlet being offset relative to the permeating region whereby it is substantially in parallel with the length of said other part of said second enlarged cross-section portion.
11. A hollow fiber permeability apparatus according to Claim 1, comprising a guide plate positioned on said shorter side of said flattened cross-section opposite at least the tubular element for delivering said first fluid, said guide plate terminating short of said longer sides of said flattened cross-section, and wherein said first fluid from said tubular element is distributed by said guide plate in said first en-larged cross-section portion.
