Assembly-type cartridge block and hollow-fiber membrane module comprising same
The present invention relates to an assembly-type cartridge block enabling various types of cartridges, and a hollow-fiber membrane module comprising the same. The assembly-type cartridge block of an embodiment of the present invention comprises: a body part having a plurality of hollow-fiber membranes therein and having mesh parts formed respectively at the upper and lower parts thereof; and a fastening part formed on a side surface of the body part and configured to be fastened to an adjacent assembly-type cartridge block. Further, the hollow-fiber membrane module of an embodiment of the present invention comprises: a housing unit including a first fluid inlet, a first fluid outlet, a second fluid inlet, and a second fluid outlet; and a cartridge unit installed inside the housing unit and formed by fastening a plurality of assembly-type cartridge blocks, each of the assemble type cartridge blocks having a plurality of hollow-fiber membranes therein.
1. A hollow fiber membrane module comprising:
a housing unit having a first fluid inlet, a first fluid outlet, a second fluid inlet, and a second fluid outlet; and
a plurality of cartridges disposed in the housing unit, the plurality of cartridges being spaced apart from each other,
wherein
each of the cartridges comprises a plurality of assembly type cartridge blocks fastened to each other,
each of the assembly type cartridge blocks comprises:
a body part having a plurality of hollow fiber membranes therein, the body part having a mesh part configured to allow a fluid to be introduced into the body part therethrough; and
a fastening part formed on the body part, the assembly type cartridge blocks being fastened to each other by means of the fastening parts thereof, and
the fastening part comprises fastening protrusion on one side of the body part and a fastening recess on the other side of the body part, such that two adjacent assembly type cartridge blocks are fastened to each other by inserting the fastening part of one of the two adjacent assembly type cartridge blocks into the fastening recess of the other thereof.
2. The hollow fiber membrane module according to claim 1 , wherein the body part has a shape of a polygonal prism.
3. The hollow fiber membrane module according to claim 1 , wherein the body part has a shape of a fan-shaped prism with a fan-shaped base plane or a shape of a doughnut-shaped and fan-shaped prism formed by cutting an end part of a fan-shaped prism in such a way that a base plane thereof has an arc shape in its entirety.
4. The hollow fiber membrane module according to claim 1 , wherein the body part is provided at opposite ends thereof with potting parts configured to bind the hollow fiber membranes together and to fill gaps between the hollow fiber membranes.
5. The hollow fiber membrane module according to claim 1 , wherein at least one of the cartridges further comprises a dummy cartridge block which has flow membranes therein or is filled with fluid impermeable membranes, the flow membranes configured to allow a fluid to flow therethrough without moisture exchange.
6. The hollow fiber membrane module according to claim 1 , wherein the housing unit comprises:
a housing cap having the first fluid inlet; and
a fluid guide formed on the housing cap, the fluid guide configured to uniformly supply a first fluid introduced through the first fluid inlet to the cartridge unit.
