Description
Technical field
This utility model relates to a kind of carrying out the granule of special object in solid-liquid, solid-gas, Liquid-liquid mixing thing
Separate and the equipment of sedimentation, particularly to a kind of flat board permeable membrane device using column dielectrophoresis electrode.
Background technology
Permeable membrane isolation technics in nearly 30 years owing to it is easy to operate, process equipment is compact, separation efficiency is high,
Low power consumption and other advantages and developing rapidly becomes heterogeneous in industry (mainly in solid-liquid, solid and gas and liquid liquid etc.) and separates
Important process method.But, in osmosis membrane filters technique, this inevitable problem of fouling membrane begins
Exist eventually, and become this technique fatal defects in reality is applied.Fouling membrane is due to film table
Due to the deposition of microgranule, colloidal particle, solute molecule or antibacterial, virus etc. or multiply and lead in face and fenestra
The Pore Blocking that causes or diminish, caused the increase of membrane resistance, so that film transit dose declines, reduced film
The consequences such as service life.Such as, commonly used super/micro-filtration membrane in solid-liquid separation, its film transit dose due to
Fouling membrane can reduce about 50% after the work of nearly one hour；And due to the absorption of solid granule and stifled
Plug, this pollution is the most reversible.Nanofiltration and reverse osmosis membrane etc. are in Liquid liquid Separation, due to concentration polarization
Produced gel layer can form a not permeable layer on film surface, thus greatly increase membrane resistance and pass through
The requirement of pressure, this fouling membrane can be removed by Membrane cleaning, referred to as reversible membrane fouling.
The industrial method being often used in cleaning fouling membrane is broadly divided into physical cleaning and Chemical cleaning, Chemical cleaning
It is by using medicament to be dissolved by insoluble pollutant and to flush out membrane module.But, Chemical cleaning not only by
The running cost of filtering technique is increased in the use of medicament, and due to the acid or use of basic agent
Film is caused damage and pollutes.Physical cleaning mainly includes that low pressure high flow rate cleans, equipressure is rinsed, instead
The methods such as flushing, negative pressure cleaning, mechanical curettage, industry commonly uses be high speed backwash and air water anti-
Developing technique.But, above two technique all must in cleaning process stopper film filtering technique, and need
High pressure and be used for rinsing higher than the water of aquifer yield two to three times, power consumption height, water consumption is big.
Ultrasound wave is believed to realize preventing a method of fouling membrane.But, due to high-strength ultrasonic pair
Erosion that permeable membrane is caused and destruction, and huge ultrasound wave generates system and hinders it industrially
Application.Electron-osmosis film based on principle of electrophoresis in last century the seventies proposed by Manegold etc., and by
Henry etc. experiments prove that its feasibility.But, this method is unsuitable for for polyion complexity
Industrial condition, and its high energy consumption also counteracts that its being widely used industrially.In addition, bare electrode
Use at electrophoresis also improves the danger that may and shock by electricity of short circuit, and the electrochemistry occurred on electrode is anti-
PH value change should be not only resulted in, even can generate chemical by-products that is poisonous or that pollute environment.
