Abstract

The invention discloses a multifunctional membrane filtering system. The multifunctional membrane filtering system comprises a stock solution tank, a power module, a membrane filtering module and a control module; the power module comprises a centrifugal pump, a driving motor and a frequency converter; the control module controls the frequency converter to adjust the rotating speed of the drivingmotor; the driving motor drives the centrifugal pump to convey a stock solution or a chemical cleaning solution from the stock solution tank to the membrane filtering module at different pressures; the membrane filtering module comprises a plurality of membrane component groups which are connected in parallel through pipelines; a control valve is arranged on each of a water inlet pipeline and a water outlet pipeline of each of the membrane component groups; the control module controls the opening and closing of the control valves on the water inlet pipeline and the water outlet pipeline of each group of the membrane component groups and simultaneously selects one or more groups of the membrane component groups for filtering. The multifunctional membrane filtering system integrates a plurality of types of membrane components, can meet different membrane filtering requirements by only adopting one centrifugal pump which is provided with the frequency converter, is compact in structure and convenient to operate, and can meet the requirements of different membrane filtering tasks.

Description

technical field [0001] The invention relates to the field of membrane filtration equipment, in particular to a multifunctional membrane filtration system. Background technique [0002] Membrane separation technology is a technology based on membrane materials with selective separation function to realize the separation, purification and concentration of different components of feed liquid. It was initially used in high-end fields such as military, aerospace, and atomic energy. It is becoming more and more widespread and is recognized as one of the most promising high-tech in the 21st century. Membrane filtration technology is a screening process related to the pore size of the membrane. The pressure difference on both sides of the membrane is used as the driving force, and the membrane is used as the filter medium. The micropores only allow water and small molecular substances to pass through to become the permeate, and the substances in the original solution whose volume i...
