Description

[0001] HOLLOW FIBER MEMBRANE MODULE [0002]

The present invention relates to a hollow fiber membrane module, and more particularly, to a hollow fiber membrane module which has a long residence time of a fluid to uniformly utilize the entire hollow fiber membrane, thereby maximizing the performance of the hollow fiber membrane with the same area, Module.

The hollow fiber membrane module may be a gas separation module, a humidification module, or a water treatment module.

Fuel cells are power generation cells that produce electricity by combining hydrogen and oxygen. Unlike conventional chemical batteries, such as batteries and accumulators, fuel cells can produce electricity continuously as long as hydrogen and oxygen are supplied, and they are twice as efficient as internal combustion engines because they have no heat loss. In addition, since the chemical energy generated by the combination of hydrogen and oxygen is directly converted into electric energy, the emission of pollutants is low. Therefore, the fuel cell has an advantage that it is not only environmentally friendly but also can reduce the concern about resource exhaustion due to an increase in energy consumption. Such a fuel cell can be classified into a polymer electrolyte membrane fuel cell (PEMFC), a phosphoric acid fuel cell (PAFC), a molten carbonate fuel cell (MCFC), a solid oxide fuel cell SOFC), and an alkaline fuel cell (AFC). Each of these fuel cells operates basically on the same principle, but the type of fuel used, the operating temperature, the catalyst, and the electrolyte are different from each other. Among them, polymer electrolyte fuel cells are known to be most promising not only in small size stationary power generation equipment but also in transportation system because they operate at a lower temperature than other fuel cells and can be miniaturized because of their high output density.

One of the most important factors for improving the performance of a polymer electrolyte fuel cell is to supply a certain amount of water or more to a polymer electrolyte membrane (PEM) of a Membrane Electrode Assembly (MEA) Thereby maintaining the water content. When the polymer electrolyte membrane is dried, the power generation efficiency is rapidly lowered. The method of humidifying the polymer electrolyte membrane is as follows: 1) a bubbler humidification method in which a pressure vessel is filled with water, a subject gas is passed through a diffuser to supply water, and 2) A direct injection method in which water is directly supplied to the gas flow pipe through calculation using a solenoid valve, and 3) a humidifying membrane method in which water is supplied to a fluidized bed of gas using a polymer separator. Among them, the humidifying membrane type which humidifies the polymer electrolyte membrane by providing water vapor to the gas supplied to the polymer electrolyte membrane using a membrane selectively permeable to only the water vapor contained in the exhaust gas is advantageous in that the humidifier can be made lighter and smaller.

The selective permeable membrane used in the humidifying membrane method is preferably a hollow fiber membrane having a large permeation area per unit volume when a module is formed. That is, when the humidifier is manufactured using the hollow fiber membrane, the hollow fiber membrane having a large contact surface area can be highly integrated, so that the humidification of the fuel cell can be sufficiently performed even at a small capacity, and low cost materials can be used. Moisture and heat contained in the unreacted gas can be recovered and reused through the humidifier.

However, in the case of a conventional module in which a hollow fiber membrane is applied, there is a disadvantage that the entire hollow fiber membrane applied to the product is not fully utilized due to asymmetry of the inlet and outlet through which the fluid flows, and uneven flow resistance caused by the hollow fiber membrane.

FIG. 2 is a cross-sectional view of the hollow fiber membrane module of FIG. 1 taken along the line A-A '.
3 to 6 are cross-sectional views of a hollow fiber membrane module according to second to fifth embodiments of the present invention.

Hereinafter, embodiments of the present invention will be described in detail so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.

FIG. 1 is a partially exploded perspective view of a hollow fiber membrane module according to a first embodiment of the present invention, and FIG. 2 is a cross-sectional view of the hollow fiber membrane module of FIG. 1 taken along line A-A '. 3 to 6 are cross-sectional views of a hollow fiber membrane module according to second to fifth embodiments of the present invention.

The hollow fiber membrane module shown in FIGS. 1 to 6 includes a humidifying module as an embodiment. However, the hollow fiber membrane module is not limited to the above-described humidification module, and may be a gas separation module or a water treatment module.

Hereinafter, the hollow fiber membrane module according to the first embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG. Referring to FIGS. 1 and 2, the hollow fiber membrane module 10 includes a housing part 1, hollow fiber membrane bundles 41 and 42, a potting part 2, and covers 51 and 52.

The housing part (1) and the covers (51, 52) are members constituting the external shape of the hollow fiber membrane module (10). The housing part 1 and the covers 51 and 52 may be made of hard plastic such as polycarbonate or metal. In addition, the housing part 1 and the covers 51 and 52 may have a rectangular cross-sectional shape in the width direction as shown in FIG. 1, or may be circular. The square may be a square, a square, a trapezoid, a parallelogram, a pentagon, a hexagon, or the like, and the square may have rounded corners. Also, the circular shape may be an elliptical shape.

Both open ends of the housing part 1 are embedded in the potting part 2 and the potting part 2 is surrounded by the peripheral parts 12 and 13 of the housing part 1. An inlet 121 through which the second fluid is supplied and an outlet 122 through which the second fluid passed through the inside of the housing part 1 are formed in the peripheral parts 12 and 13.

A hollow fiber membrane bundle (41, 42) made up of a plurality of hollow fiber membranes (45) selectively passing moisture through the housing unit (1) is embedded. Here, the material of the hollow fiber membrane 45 is well known in the art and will not be described in detail here.

The hollow fiber membrane bundles 41 and 42 may have a wide shape. The wide shape of the hollow fiber membrane bundles 41 and 42 means a shape having a wide width and a thin thickness while being funneled in the longitudinal direction. At this time, the length of the width is longer than the thickness.

The thickness of the hollow fiber membrane bundle 41, 42 may be 20 to 200 mm, preferably 40 to 100 mm. When the thickness of the hollow fiber membranes 41 and 42 is within the above range, the penetration of the first fluid penetrating into the hollow fiber membranes 41 and 42 is easy. Accordingly, the hollow fiber membrane module 10 maximizes the flow efficiency by improving the flow uniformity of the first fluid flowing to the outside of the hollow fiber membrane bundles 41 and 42, thereby maximizing the capacity of the hollow fiber membrane module 10 It is possible to minimize the additional use of the hollow fiber membrane to increase the cost, and to reduce the size of the hollow fiber membrane module 10.

The ratio of the thickness to the width of the hollow fiber membrane bundle 41, 42 may be 5 to 100%, and preferably 10 to 60%. If the thickness ratio of the hollow fiber membrane bundles 41 and 42 to the width of the hollow fiber membrane bundles 41 and 42 is less than 5%, the hollow fiber membrane bundle 41 and 42 may not include a sufficient hollow fiber membrane 45, The length of the hollow fiber membrane 45 is too short to realize the hollow fiber membrane module 10.

The hollow fiber membrane bundles 41 and 42 may include 30 to 60% by volume of the hollow fiber membrane 45 with respect to the total volume thereof. If the content of the hollow fiber membrane 45 is less than 30% by volume, the hollow fiber membrane module 10 may not be sufficiently contained in a limited space, thereby increasing the volume of the hollow fiber membrane module 10. When the content of the hollow fiber membrane module exceeds 60% The density of the hollow fiber membrane 45 is high and the pressure drop due to the external fluid flow of the hollow fiber membrane 45 may become too large.

The potting portion 2 binds the hollow fiber membranes 45 at both ends of the hollow fiber membrane bundles 41 and 42 to fill the voids between the hollow fiber membranes 45. The potting portion 2 may be in contact with the inner surfaces of both ends of the housing portion 1 to seal the housing portion 1. The material of the potting part 2 is well known and will not be described in detail here.

The potting part 2 is formed in each of both ends of the housing part 1 so that both ends of the hollow fiber membrane bundle 43 are fixed to the housing part 1. As a result, both ends of the housing part 1 are blocked by the potting part 2, and a flow path through which the second fluid passes is formed therein.

The covers (51, 52) are coupled to both ends of the housing part (1). A first fluid inlet 53 and a first fluid outlet 54 are formed in the covers 51 and 52, respectively. The first fluid introduced into the first fluid inlet 53 passes through the inner duct of the hollow fiber membrane 45 and exits to the first fluid outlet 54.

2, the potting portion 2 may be inclined upward toward the center of the housing portion 1 at a substantially middle portion of the end 12a of the peripheral portions 12 and 13, The hollow fiber membranes 45 may pass through the potting part 2 to expose the channel at the end of the potting part 2. A sealing member S is put on an end 12a of the peripheral portion 12 or 13 not covered by the potting portion 2 and the cover 51 or 52 presses the sealing member S and the housing portion 1 ). ≪ / RTI >

The hollow fiber membrane module 10 may include a plurality of hollow fiber membrane bundles 41 and 42 and a partition wall 9 for partitioning the plurality of hollow fiber membrane bundles 41 and 42. A second fluid through hole 91 is formed in the partition wall 9 to allow the second fluid to pass through the partition wall 9 through the second fluid through hole 91 to the outside of the hollow fiber membrane 45 To flow.

The plurality of partition walls 9 may be disposed so as to surround each of the plurality of hollow fiber membrane bundles 41 and 42 so as to surround the hollow fiber membrane bundles 41 and 42, Can be divided.

The first fluid is supplied into the housing part 1 through the first fluid inlet 53 of the covers 51 and 52 and flows into the hollow fiber membranes 45 so that the covers 51 and 52 Through the first fluid outlet 54 of the hollow fiber membrane module 10. The second fluid is supplied to the peripheral portions 12 and 13 of the housing part 1 through the injection port 121 of the housing part 1 and then flows through the second fluid through- Flows through the partition wall 9 through the opening 91 to the outside of the hollow fiber membranes 45 and flows through the second fluid through hole 91 of the partition wall 9 to the periphery of the housing part 1 Is discharged to the outside of the housing part (1) through the discharge port (122) of the housing part (1).

That is, in the conventional hollow fiber membrane module, the first fluid or the second fluid has only a flow in one direction with respect to the longitudinal direction of the hollow fiber membrane bundle, and the hollow fiber membrane module 10 has the first fluid or the second fluid The first fluid or the second fluid flows in the forward direction and flows in the reverse direction as well. However, the flow paths of the forward flow and the reverse flow may be different from each other.

Accordingly, it is possible to maximize the time required for the first fluid or the second fluid to stay in the hollow fiber membrane module 10, thereby uniformly utilizing the entire hollow fiber membrane 45, and maximizing mass transfer efficiency.

In order to divide the flow of the first fluid or the second fluid, the hollow fiber membrane module 10 divides the forward flow and the reverse flow in the longitudinal direction of the hollow fiber membrane bundles 41, 42 of the first fluid A second fluid divider plate (8) for dividing the forward flow and the backward flow of the second fluid in the longitudinal direction of the hollow fiber membrane bundle, and a combination thereof; And a plurality of partitioning plates.

Specifically, when dividing the flow path of the first fluid into two, the first cover (51) is divided into a first fluid inlet (53) and a first fluid outlet (54) 1 cover < / RTI > At this time, both the first fluid inlet 53 and the first fluid outlet 54 may be formed in the first cover 51, and the first fluid outlet may be formed in the second cover 52 . The first fluid supplied to the first fluid inlet (53) flows forward only through the first hollow fiber membrane bundle (41) by the first fluid divider plate (7).

The first fluid divider plate 72 of the second cover may be disposed between the positions opposed to the first fluid divider plates 71 of the first cover. When the first fluid divider plate (72) of the second cover is disposed at a position facing the first fluid divider plate (71) of the first cover, the first fluid flowing in the forward direction passes through another hollow fiber membrane bundle or hollow fiber membrane It may not be able to be fed into other parts of the bundle.
