Embodiment Construction

[0023] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.

[0024] A hollow fiber porous membrane filtration module, referring to Fig. 1 and Fig. 2, its main structure includes a water outlet pipe 1, a membrane bundle cup 51, an aeration pipe 2 and a hollow fiber membrane bundle 53. Wherein, the water outlet pipe 1 is connected with a water suction pump for discharging filtered water. The water suction pump is not shown in the figure, and the water outlet pipe can be designed as openings at one end or openings at both ends as required. The membrane bundle cup 51 is used for connecting the hollow fiber membrane bundle 53 and communicates with the outlet pipe 1 through the outlet hose 52 . The aeration pipe 2 is communicated with the air source, and its peripheral wall is provided with aeration holes 21 . The hollow fiber membrane bundle 53 is immersed in the sewage to be treated, while referring to Figure 4 , the...

Abstract

The invention relates to a hollow fiber porous membrane filter component which comprises a water outlet pipe connected with a water suction pump and used for discharging filtered water, a membrane bundle cup used for connecting a hollow fiber membrane bundle and communicated with the water outlet pipe by a water outlet hose, an aeration pipe communicated with air supply and provided with aeration holes on the surrounding wall, and the hollow fiber membrane bundle immersed in sewage to be treated and arranged in a U-shape form, with the two ends connected with the membrane bundle cup and the bending part arranged on the aeration pipe. The aeration holes on the aeration pipe are arranged at positions corresponding to the bending part of the hollow fiber membrane bundle. The component has the advantages that the membrane surface of the whole membrane bundle is not easy to be fouled and blocked, the connecting root part of the membrane bundle is not easy to be damaged, the structure is simple and easy to be maintained, scale production is easy to form and the like.

Description

technical field [0001] The invention relates to filtering equipment, in particular to a hollow fiber porous membrane filtering module. Background technique [0002] With the development of membrane technology and people's continuous higher requirements for water purification technology, membranes are increasingly used in sewage purification treatment. Membrane fouling has always been a problem in practice. The submerged hollow fiber porous membrane filter module can solve membrane fouling to a certain extent. [0003] The submerged hollow fiber porous membrane filter module generally connects the two ends of the hollow fiber membrane bundles to the water collection plates or water collection pipes that are separated and opposite to each other, and keeps the membrane bundles loose and not in contact with each other. In the water to be treated, it is equipped with an aeration mechanism and a cleaning mechanism to keep the membrane bundle in a shaking state to prevent fouling...
