Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a pressurized hollow fiber membrane module capable of replacing a hollow fiber membrane element,

The present invention can replace only the hollow fiber membrane element, which is a core component mainly related to the performance of the pressurized hollow fiber membrane module, in the module of the pressurized hollow fiber membrane which has reached the end of its life or the performance can not be restored, The present invention relates to a pressurized hollow fiber membrane module capable of replacing a hollow fiber membrane element capable of reducing a hollow fiber membrane element and a method of manufacturing the same.

The pressurized hollow fiber membrane module requires replacement of the hollow fiber membrane due to deterioration of the performance or lifetime of the hollow fiber membrane depending on the long-term operation. Skids and the like are different depending on the characteristics of the water treatment process of the module manufacturer. The cost of repairing the equipment such as the skid or the cost of the new production is enormously required.

Therefore, the positions of the raw water inflow portion, the treated water discharge portion, the concentrated water discharge portion, the cleaned air inflow portion and the drain portion are made the same so that the module can be replaced without changing or modifying the installed skid, The extruded pipe capable of determining the length of the module and the baffle to be inserted into the extruded product, the extruded material at both ends of the membrane module element and the extruded foam In the module of the pressurized hollow fiber membranes which can not be restored or the performance can not be restored by applying the adhesive such as adhesive, heat fusion, and rotary fusion, the hollow fiber membrane element A hollow fiber membrane module capable of replacing a hollow fiber membrane element capable of replacing only a hollow fiber membrane module and a manufacturing method thereof Will.

The pressurized hollow fiber membrane module of the microfiltration (MF) or ultrafiltration (UF) grade requires a facility such as a skid capable of mounting pumps, valves, and modules in order to perform the filtration function. The skids need to be changed according to the characteristics of the water treatment process of the module manufacturer. In order to replace the modules with different manufacturers, it is necessary to modify the equipment such as skids, So that a high cost burden is required for new production, and the like.

In order to mount a module on a skid, watertightness and internal pressure of the module are required such as inflow of raw water, discharge of treated water, discharge of concentrated water, inflow of cleaning air, and the like. And is fixed in a screw or clamp shape to maintain the internal pressure.

In order for the module to be replaced without modification or modification of the installed skid, the positions of the raw water inflow portion, the treated water discharge portion, the concentrated water discharge portion, the cleaned air inflow portion, and the drain portion should be the same.

Since the position of the coupling part differs according to the manufacturer, it has not been possible to replace each other, and there have been many attempts and efforts to standardize the shape of the module. However, the different operating modes and the module type have different advantages It is difficult to standardize the module in practice.

However, up to now, in the water treatment technology using the reverse osmosis method, the pressurized blanket is reused and only the RO element is used instead of the reverse osmosis (RO) element.

Therefore, in water treatment technology using microfiltration or ultrafiltration pressurized hollow fiber membrane module, the performance of the pressurized hollow fiber membrane module capable of replacing the module without modification or modification of the existing skid There is an increasing need to develop a technique for replacing only a hollow fiber membrane element, which is a core component, to reduce costs.

In the present invention, it is possible to replace only the hollow fiber membrane element, which is a core part related to the performance of the pressurized hollow fiber membrane module, capable of replacing the module without changing or modifying the existing skid in the conventional pressurized hollow fiber module So that the operation cost can be reduced in the long-term operation of the water treatment system.

In order to achieve the above object, the present invention provides a pressurized hollow fiber membrane module comprising a raw water inflow port 100, a treated water outflow port 200, a concentrated water and an air outflow port 300, and a concentrated drain port 400, A module cap (10) comprising upper and lower portions of the pressurized hollow fiber membrane module; A module cap injection (30) located inside each of the upper and lower module caps and connected to the concentrated water and the air outlet port (300) or the concentrated drain port (400); An extrusion pipe 50 inserted into upper and lower module cap projections 30 and capable of determining the length of the module; An O-ring (20) holding airtightness between the module cap (10) and the module cap projections (30); And a binding means for binding between the module cap (10) and the module cap injection (30), and a replaceable hollow fiber membrane module and a method of manufacturing the same.

The binding means may be a clamping coupling 80 or a threaded coupling 90 or a combination of a clamping coupling 80 and a threaded coupling 90.

In order for the module to be replaced without changing or modifying the installed skid, the positions of the raw water inflow portion, the treated water discharge portion, the concentrated water discharge portion, the clean air inflow portion and the drain portion are made to be the same, The position and size of the extruded product at both ends of the membrane module element are determined according to the replacement module, and the baffle inserted into the injection molded product and the extrusion pipe capable of determining the length of the module, Which is a key component related to the performance of a membrane module in a pressurized hollow fiber membrane module which can not be recovered in its lifetime or its performance can not be recovered by applying an adhesive, So that it can be replaced.

The present invention reduces the cost by replacing only the hollow fiber membrane element, which is a core component related to the performance of the pressurized hollow fiber membrane module, in the module of the pressurized hollow fiber membrane that has reached the end of its life or the performance can not be restored. It can be said that it can be done.

In particular, the upper and lower module caps and clamps are rarely faulty and have a long lifetime. Therefore, the upper and lower module caps and clamps are reused and only the membrane module elements are replaced Not only is it economically advantageous, but it can also be used over the long term without changing existing water treatment systems.

Therefore, in water treatment technology using microfiltration or ultrafiltration pressurized hollow fiber membrane module, the performance of the pressurized hollow fiber membrane module capable of replacing the module without modification or modification of the existing skid It is possible to replace only the hollow fiber membrane element, which is a core part, thereby reducing the operation cost of the entire water treatment system.
