BACKGROUND OF THE INVENTION Hollow fibre membranes have been widely used m the fields such as water treatment, biological separation and air filtration.

Based on the above finding, the present invention has been achieved. Now, the present invention is further described in conjunction with the drawings. However, it should be understood that these drawings are merely to illustrate the present invention, not limiting the scope of the invention. Figure 1 is a sectional view of the hollow fibre membrane module with a fixed structure according to a preferred embodiment of the present invention. As illustrated in Figure 1, the hollow fibre membrane module is a cylinder structure. The central tube 1 is also a cylinder, and there are small holes 11 drilled on the outer wall thereof. The separate fixed rings 2 are distributed in equidistance on the central tube 1 for separating and fixing the hollow fibre membranes 6. The radial rib plates 3 corresponding to each separate fixed ring 2 forms a plane along the axis of the central tube 1. The hollow fibre membranes 6 are also in the form of cylinder and parallel with the central tube 1, and the ends thereof and the central tube 1 are fixed together. These hollow fibre membranes 6 are arranged in parallel through the separate fixed rings 2.

In another embodiment, when only one separate fixed ring 2 is used, it is located at the middle of the central tube 1. The operation principle of the hollow fibre membrane module is as follows: when the ultrafiltration membrane is an internal pressure membrane, raw water flows into the inlet 8 located at one end of the hollow fibre membranes 6, then the filtrated produced water flows into the central tube 1 via the through-hole on the central tube 1 through the space between the bundle, and flows out of the produced water outlets 9 on both ends of the central tube 1; and, the raw water without being filtrated flows into the other end of the membranes 6 via the inner side of the membranes, so as to form concentrated water and flow out of the concentrated water outlet 10, wherein the produced water outlet 9 can be located at one end of the central tube 1 only; and, when the ultrafiltration membrane is an external pressure membrane, the inlet 8 and the concentrated water outlet 10 become the produced water outlets, and the produced water outlet 9 becomes an aeration outlet, thus the produced water flows out of the inlet 8 and the concentrated water outlet 10 via the outer sides of the membranes. Figure 2 illustrates the structure of the separate fixed ring 2 in the preferred embodiment according to Figure 1. As illustrated in Figure 2, the separate fixed ring 2 is composed of an outer ring 4, an inner ring 5, and radial rib plates 3 located between the outer ring and the inner ring in equidistance. There are many through-holes 12 on the outer ring 4, the inner ring 5 is fixed on the central tube 1, and the radial rib plate 3 has a length of no less than 5mm, a width of no less than 2mm and a thickness of no less than 2mm, generally. When mounting, the outer ring 4 and the radial rib plates 3 can be integrated, or the outer ring can be formed into many separating bodies respectively inserted into the radial rib plates 3. The amount of the separafing bodies is at least 2, and at most equal to the amount of the radial rib plates 3. The separating bodies and the radial rib plates 3 can be bonded together, or the separating bodies and the radial rib plates 3 can be clipped together, and the separating bodies can be easily separated from the radial rib plates 3. The hollow fibre membranes are mounted in a cyclic space formed by the outer ring 4, the inner ring 5 and the radial rib plates 3 of the separate fixed ring in equal amount. The main advantages of the present invention are as follows: The separate fixed ring fixes the bundle, correspondingly separates the bundle, and forms a channel between the bundle, thus greatly reducing the resistance of the membranes against water stream. Raw water flows into the inlet, then penetrates through the wall of the hollow membranes to form produced water, while raw water flows to the other end of the inner wall of the membranes to form concentrated water. Through the above channel formed by the separate fixed rings, the produced water can flow into the produced water outlet without being blocked, and the concentrated water can be discharged from the concentrated water outlet, thus greatly increasing the operating efficiency of the membranes. Therefore, when the diameter and the length of the membrane module are larger, the configuration of the present invention can still remain the ordered arrangement of the membranes and the high efficient operation, thus ensuring the collection and flow of the produced water. Although the present invention has been illustrated in detail for the purpose of clarity and understanding, upon reviewing the description of the present application, those skilled in the art will readily understand that various amendments and modifications can be made in the present invenfion without departure of the spirit and substance of the present invenfion. Such amendments and modifications fall within the scopes of the attached claims and their equivalents. What is claimed is: 1.

Through extensive and intensive investigation, the inventors of the present invention
have found that by incorporating a fixing structure such as a separate fixed ring into the
hollow fibre membrane module, a hollow fibre membrane module with a reasonable structure,
which has more reasonable and efficient water stream distribution and produced water
collection, improved hollow membranes availability, and higher filtration efficiency, can be
obtained. Based on the above finding, the present invention has been achieved.
Now, the present invention is further described in conjunction with the drawings.
However, it should be understood that these drawings are merely to illustrate the present
invention, not limiting the scope of the invention.
Figure 1 is a sectional view of the hollow fibre membrane module with a fixed structure
according to a preferred embodiment of the present invention. As illustrated in Figure 1, the
hollow fibre membrane module is a cylinder structure. The central tube 1 is also a cylinder,
and there are small holes 11 drilled on the outer wall thereof. The separate fixed rings 2 are
distributed in equidistance on the central tube 1 for separating and fixing the hollow fibre
membranes 6. The radial rib plates 3 corresponding to each separate fixed ring 2 forms a
plane along the axis of the central tube 1. The hollow fibre membranes 6 are also in the form
of cylinder and parallel with the central tube 1, and the ends thereof and the central tube 1 are
fixed together. These hollow fibre membranes 6 are arranged in parallel through the separate
fixed rings 2. The above member composed of the central tube 1, the hollow fibre membranes
6 and the separate fixed rings 2 are inserted into the bearing shell 7, so as to seal the outer
edge of the ends of the membranes and the bearing shell 7, In another embodiment, the ends
of the membranes, the central tube 1 and the bearing shell 7 can be directly integrated with a
bonding material. In another embodiment, when only one separate fixed ring 2 is used, it is
located at the middle of the central tube 1.
The operation principle of the hollow fibre membrane module is as follows: when the
ultrafiltration membrane is an internal pressure membrane, raw water flows into the inlet 8
located at one end of the hollow fibre membranes 6, then the filtrated produced water flows
into the central tube 1 via the through-hole on the central tube 1 through the space between
the bundle, and flows out of the produced water outlets 9 on both ends of the central tube 1;
and, the raw water without being filtrated flows into the other end of the membranes 6 via the
inner side of the membranes, so as to form concentrated water and flow out of the
concentrated water outlet 10, wherein the produced water outlet 9 can be located at one end of
the central tube 1 only; and, when the ultrafiltration membrane is an external pressure
membrane, the inlet 8 and the concentrated water outlet 10 become the produced water outlets,
and the produced water outlet 9 becomes an aeration outlet, thus the produced water flows out
of the inlet 8 and the concentrated water outlet 10 via the outer sides of the membranes.
Figure 2 illustrates the structure of the separate fixed ring 2 in the preferred embodiment

according to Figure 1. As illustrated in Figure 2, the separate fixed ring 2 is composed of an
outer ring 4, an inner ring 5, and radial rib plates 3 located between the outer ring and the
inner ring in equidistance. There are many through-holes 12 on the outer ring 4, the inner ring
5 is fixed on the central tube 1, and the radial rib plate 3 has a length of no less than 5mm, a
width of no less than 2mm and a thickness of no less than 2mm, generally. When mounting,
the outer ring 4 and the radial rib plates 3 can be integrated, or the outer ring can be formed
into many separating bodies respectively inserted into the radial rib plates 3. The amount of
the separafing bodies is at least 2, and at most equal to the amount of the radial rib plates 3.
The separating bodies and the radial rib plates 3 can be bonded together, or the separating
bodies and the radial rib plates 3 can be clipped together, and the separating bodies can be
easily separated from the radial rib plates 3. The hollow fibre membranes are mounted in a
cyclic space formed by the outer ring 4, the inner ring 5 and the radial rib plates 3 of the
separate fixed ring in equal amount.
The main advantages of the present invention are as follows:
The separate fixed ring fixes the bundle, correspondingly separates the bundle, and
forms a channel between the bundle, thus greatly reducing the resistance of the membranes
against water stream. Raw water flows into the inlet, then penetrates through the wall of the
hollow membranes to form produced water, while raw water flows to the other end of the
inner wall of the membranes to form concentrated water. Through the above channel formed
by the separate fixed rings, the produced water can flow into the produced water outlet
without being blocked, and the concentrated water can be discharged from the concentrated
water outlet, thus greatly increasing the operating efficiency of the membranes. Therefore,
when the diameter and the length of the membrane module are larger, the configuration of the
present invention can still remain the ordered arrangement of the membranes and the high
efficient operation, thus ensuring the collection and flow of the produced water.

and understanding, upon reviewing the description of the present application, those skilled in
