Integrated hollow fiber membrane component integrating backwashing function

Technical Field

The invention belongs to the field of separation, and particularly relates to an integrated hollow fiber membrane module integrating a backwashing function.

Background

The hollow fiber membrane is an important form of separation membrane, and has been widely applied to municipal, chemical and medical fields such as pure water purification, sewage purification, medicine purification, juice concentration and the like. In the long-term use of the hollow fiber membrane module, various impurities can be trapped on the surface of the membrane, so that the membrane pores are blocked by the impurities, and the separation performance of the membrane is reduced. For this reason, a membrane cleaning and regenerating process is often designed during the use of the membrane.

At present, when a hollow fiber membrane component is used for backwashing, a corresponding backwashing pipeline needs to be externally connected, and the pipeline connection is complex. Usually, when the hollow fiber membrane module is switched from a normal operation state to a backwashing state, a plurality of valve pipelines need to be adjusted in sequence, and the operation is complex. The existing hollow fiber membrane module has complicated backwashing pipeline connection, complicated backwashing operation, and easy damage to the membrane module and even membrane equipment due to slight errors in the operation process.
