Description
Technical Field
The present invention relates to a separation membrane module unit, and more particularly, to a separation membrane module unit which includes a separation membrane module, a support frame, a vertical fixing frame, an external fixing frame, and a diffuser, and which can uniformly wash the entire outer and inner sides of a hollow fiber membrane bundle of the separation membrane module, thereby increasing an effective washing area, and thus increasing the performance of the separation membrane module while remarkably increasing the lifespan of the separation membrane module, and which can allow a user to selectively and conveniently additionally install a plurality of separation membrane unit modules in a unit form according to filtration capacity.
Background
In general, a separation membrane module, which is an immersion type filtration apparatus, is installed inside a reaction tank, and sewage and wastewater can be filtered by using water permeability of the separation membrane module, and in order to increase water permeability of the separation membrane module, it is necessary to remove impurities attached to the separation membrane module at a certain period by means of, for example, a cross-flow filtration method, a reverse washing method, an air washing method, or the like.
As an immersion type filtration apparatus using the above-described separation membrane module (hollow fiber membrane module), there is disclosed an immersion type filtration apparatus including a plurality of hollow fiber membrane modules, a filtrate capturing and transferring block for supporting the upper ends of the hollow fiber membrane modules, an air injecting and transferring block provided with an air injection port for supporting the lower ends of the hollow fiber membrane modules, and a mesh filter, see patent document 1 (korean registered patent No. 0646001, 2006.11.07 registration).
However, in the immersion type filtration apparatus using the conventional separation membrane module (hollow fiber membrane module), since the washing air is brought into contact with only the surface of the separation membrane module exposed to the outside and cannot wash the separation membrane located inside, the entire separation membrane module cannot be uniformly washed, which leads to a problem that the effective area for washing the separation membrane is reduced and the life of the separation membrane module is further shortened.
In addition, in the immersion type filtration apparatus using the conventional separation membrane module (hollow fiber membrane module), since the same amount of air cannot be injected into each separation membrane module, the air cleaning effect differs at different portions from one another in the entire filtration apparatus, and sludge accumulates in portions where air cleaning is insufficient, thereby causing a problem of further rapid decrease in performance of the separation membrane.
Further, in the immersion type filtration apparatus using the conventional separation membrane module (hollow fiber membrane module), since the separation membrane module is manufactured in advance to have a specific filtration capacity, a user cannot selectively adjust the filtration capacity according to the filtration required from a small-scale capacity to a large-scale capacity.
Therefore, there is a need for research and development of a separation membrane unit module for a filtration apparatus, which includes a structure in which the entire outside and inside of a hollow fiber membrane portion to which a bundle-shaped form is applied in a separation membrane module can be uniformly washed, thereby increasing an effective washing area, thereby improving the performance of the separation membrane module and remarkably increasing the lifespan of the separation membrane module, and also allowing a user to selectively and conveniently additionally install a plurality of separation membrane modules configured in a unit form according to filtration capacity.

The air diffuser 500 includes a main body 510 formed with a plurality of through holes on an upper side surface thereof and disposed on a lower side of the support frame 200 to diffuse air bubbles, and a connection pipe 520 bent and extended from the lower side of the main body 510 a plurality of times so as to communicate with each other and sequentially passing through the outer fixing frames 400 disposed at the center and the upper end of the vertical fixing frame 300.
Particularly, in the air dispersion pipe 500 as described above, the extended end of the connection pipe 520 is connected to the blower 20 through a pipe, and bubbles are dispersed upward from the lower side of the support frame 200 by the driving of the blower 20 and thereby the outer surface of the hollow fiber membranes 111 of the separation membrane module 100 is washed.
In the separation membrane module unit 1000 to which the present invention is applied, which is configured as described above, the separation membrane module 100 generally includes the hollow fiber membrane bundle 110, the lower cover 130, and the upper cover 150.
Specifically, the hollow fiber membrane bundle 110 is formed by bundling a plurality of hollow fiber membranes 111.

In this case, the outer fixing frame 400 disposed at the lower end portion of the vertical fixing frame 300 is preferably fixedly mounted in an l-shape in which the l shape is inverted vertically.

In the separation membrane module unit 1000 to which the present invention is applied, configured as described above, as shown in fig. 6, the suction pump 10 is connected to the connection port 151 of the upper cover 150 of the separation membrane module 100 through the suction connection pipe 10a, so that filtered water obtained while passing through the inside of the hollow fiber membranes 111 can be sucked and treated through the connection port 151 when the suction pump 10 is driven.
In this case, in order to achieve tight connection between the suction connection pipe 10a and the connection portion of the connection port 151, it is preferable to connect by using separate male and female connectors.
Meanwhile, referring to fig. 6, when the blower 20 is driven, bubbles are emitted to the lower side of the separation membrane module 100 through the body 510 of the diffuser pipe 500 by communicatively connecting the blower 20 to the end of the connection pipe 520 of the diffuser pipe 500 through the air supply connection pipe 20 a.
In this case, in order to achieve close connection between the air blowing connection duct 20a and the connection portion of the end of the connection pipe 520 of the air-releasing pipe 500, it is preferable to use separate male and female connectors for connection.
In addition, the bubbles emitted through the main body 510 of the above-described air diffuser 500 may come into full contact with the outer surfaces of the respective hollow fiber membranes 111 in the hollow fiber membrane bundle 110 of the separation membrane module 100 via the through-holes 210 of the support frame 200.
Thereby, the entire outer and inner sides of the hollow fiber membrane bundle 110 of the separation membrane module 100 can be uniformly washed.
In other words, the entire outer surfaces of the hollow fiber membranes 111 arranged inside the hollow fiber membrane bundle 110 of the separation membrane module 100 and the hollow fiber membranes 111 arranged outside can be washed.
