Hollow fiber membrane filtering assembly

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...

AI Technical Summary

Problems solved by technology

[0007] The invention provides a hollow fiber porous membrane filter module, the main purpose of which is to overcome the shortcomings of the existing hollow fiber porous membrane filter module, which are easy to be fouled and clogged locally, the connection parts of the membrane bundles are easily damaged, the structure is complex, and it is difficult to form large-scale production.
