Description
The present invention relates to a hollow fiber membrane module, and more particularly, to a hollow fiber membrane module in which air is properly distributed so that contaminants in the hollow fiber membrane can be effectively removed.
As is well known, membrane technology is a type of separation technology that utilizes material selective permeation properties of polymeric materials.
Existing membranes are of various types, such as spiral wound, tubular, hollow, and plate and frame.
Since the hollow fiber type uses a hollow tube having a diameter of 0.2 to 2 mm and a hollow hollow tube, the ratio of the membrane area per unit volume is relatively higher than that of the other types, resulting in higher productivity.
Hollow fiber membrane is formed into a bundle of hollow fiber modules.
Among the hollow fiber membrane modules, so-called immersion hollow fiber membrane modules are used by directly immersing them in a tank of fluid to be treated.
1 is a view showing a conventional immersion hollow fiber membrane module.
As shown in FIG. 1, the conventional hollow fiber membrane module includes a hollow fiber membrane 10 having a hollow 12 therein, a support 20 coupled to a lower end of the hollow fiber membrane 10, and the hollow fiber membrane The

Here, the through hole of the air distribution unit may be formed to have a minimum flow cross-sectional area of 3.0 * 10 -4 to 3.2 * 10 -4 m 2.
The support part may have a storage space for temporarily storing the air flowing into the diffuser and the diffuser, and the air distribution unit may be formed to protrude 0.1 to 100 mm from the ceiling of the storage space.
The outer surface of the air distribution unit may be formed to gradually reduce the outer width along the protruding direction.
The air distribution unit may have a circular or polygonal cross section.
The outer surface of the air distribution unit may be provided with a guide portion for guiding air is cut or penetrated.
The air distribution unit may be detachably provided to the support unit or the diffuser.
The air distribution unit may be configured to adjust the protruding length to the ceiling of the storage space.
The air distribution unit may be configured to be screwed to the support or the diffuser.
The air distribution unit is screwed to the diffuser, the air distribution unit, the through-hole body is formed therein; An incision formed by cutting the body around the through hole; And an inclined portion whose inner width is reduced along the protruding direction.
An end of the diffuser may be configured to have a guide inclined surface formed to reduce the outer width along the protruding direction.
The guide inclined surface may be formed in surface contact with the inclined portion.
As described above, according to an embodiment of the present invention, the hollow fiber membrane is configured to include a support unit having acid pores and an air flow path provided therein to diffuse air in an area spaced from the acid pores. Contaminants in the upper region of can be removed.
In addition, by providing a through hole and an air distribution part projecting to the lower end of the diffuser, air can be properly distributed to the lower region and the upper region of the hollow fiber membrane.
In addition, the outer surface of the air distribution portion is configured such that the outer width is gradually reduced along the protruding direction, so that more air can be distributed outward along the radial direction of the support.
Further, by providing a guide portion partially cut or penetrated on the outer surface of the air distribution portion, it is possible to suppress the lean air from the region proximate to the air distribution portion.
In addition, by configuring the air distribution unit detachably to the support or diffuser, it can be easily replaced with another air distribution unit.
In addition, by screwing the air distribution unit to the support or diffuser, it is possible to control the amount of air moving to the outside of the support by adjusting the protruding length of the air distribution.
In addition, by forming an incision in the air distribution portion and by expanding or contracting the air distribution portion in the radial direction, it is possible to adjust the flow rate of the air flowing into the diffuser.
