Description
Technical field
The invention belongs to electrochemical technology fields, are related to a kind of polarized film electric adsorption system.
Background technique
Electro Sorb (Capacitive deionization, CDI) is developed in compact double layer's theoretical basis
The electrochemical treatments technique come, is mainly used in the removal of sea water desalination, industrial wastewater desalination and heavy metal ion.?
In the technology, electrode selects the porous material (such as active carbon) with very bigger serface, in the behaviour lower than hydrolysis ionization voltage
Make under voltage, it will be in ionic adsorption to electrode.Electrode electrically charged two pole plates that capacitor is formed with adion, due to this
Two pole plate spacing are very small, and electrode material specific surface area is huge, so its capacitance can be higher than classic flat-plate capacitor
109More than, a large amount of ions can be adsorbed.Traditional Electro Sorb technique includes adsorbing and being desorbed two steps.In adsorption process, with electricity
Pole electrically charged opposite ion (counter ion, counter-ions) be adsorbed in respective electrode, obtain liquid to be processed only
Change.In desorption process, clamping voltage is removed or is reversely connected voltage, adion, which has been ostracised, leaves electrode and return to liquid to be processed
In, liquid to be processed is concentrated.In desorption process, if removal voltage, the electrode of adion disengaging is incomplete, leads to electricity
Pole regeneration is not thorough；If reversal connection voltage, it is more complete to be detached from electrode for adion, but part can reach face electrode, cause pair
Face electrode regeneration is not thorough.For this purpose, being developed film Electro Sorb technique (Membrane capacitive
deionization,MCDI).In the technique, cation permselective film (abbreviation cationic membrane) and anion selectivity are saturating
Film (abbreviation anionic membrane) is crossed to be respectively placed between two electrodes.When adsorption operations, it is negative that the electrode of cationic membrane side connects power supply
The electrode of pole, anionic membrane side connects positive pole；Cation permeable cationic membrane is adsorbed on cathode in liquid to be processed, yin
Ion is adsorbed on anode through anionic membrane.When desorption manipulation, by electric voltage reverse-connection；Sun (yin) ion adsorbed is effective
Ground repels, and enters liquid to be processed through positive (yin) ionic membrane；Due to the presence of negative (sun) ionic membrane in opposite side, make these sun
(yin) ion can not be reached to lateral electrode, can only be returned in liquid to be processed；To make the regeneration efficiency of two electrodes all be mentioned
It is high.Studies have shown that, since the selectivity of film can not reach 100%, always having part same in the practical operation of film Electro Sorb technique
Ion (can reach electrode through film with the electrically charged identical ion of electrode institute, co-ions) i.e. in adsorption process.This part
Same ion can remove the counter ion in the liquid to be processed of part, to improve adsorbance in adsorption process by neutralization；?
In desorption process, by the counter ion of electrode adsorption and by the counter ion that above-mentioned same ion neutralizes returned under electrode repulsive interaction to
In treatment fluid, to improve desorption rate.
As described above, the adsorbance and desorption rate of traditional Electro Sorb can only achieve the saturated extent of adsorption of electrode material, and film
Electro Sorb is in addition to the saturated extent of adsorption of electrode material, some is since same ion exists and increased amount.It is convenient for statement,
This part can be known as the ion that works with ion.Theoretically, if the amount and electrode material saturated extent of adsorption of work ion
When roughly the same, then the adsorbance and desorption rate of film Electro Sorb can achieve twice of traditional Electro Sorb.Reach this effect,
On condition that electrode and liquid to be processed is completely separable, so as to by work limit in space between electrode and film, and work is realized
It is controllable to make ionic weight.Existing film electric adsorption device generallys use the mode (free- being tightly attached to film on electrode material
Standing membrane), electrode and liquid to be processed can not be kept completely separate.Although porous electrode material internal has centainly
Exist with ion and be used as work ion, but its amount is little and is unable to control, total adsorbance and desorption rate increase are unobvious.

Liquid outlet conductivity to be processed gradually rises；Until ion remaval rate is zero, liquid outlet conductivity to be processed reaches to be processed
When liquid initial conductivity, adsorption process terminates.
4. according to a kind of polarized film electric adsorption system described in claim 1, it is characterised in that: the desorption process is driven in peristaltic pump
It continues for being passed through liquid to be processed to intermediate water chamber under dynamic；It is reversely connected power supply, applies 1.2V and voltage, i.e. anionic membrane lateral electrode is desorbed
Room I electrode connects power cathode, and cationic membrane lateral electrode room II electrode connects positive pole, at this point, having inhaled on cathode in electrode chamber I
Attached Cl-Ion, which is ostracised, leaves cathode, enters water chamber through anionic membrane；Work ion Na+Ion is adsorbed to cathode,
The Cl combined in adsorption process by neutralization-Ion is released, and also enters water chamber, electrode chamber through anionic membrane
In II, the Na that has been adsorbed on anode+Ion, which is ostracised, leaves anode, enters water chamber through cationic membrane；Work ion Cl-Ion
It is adsorbed to anode, the Na combined in adsorption process by neutralization+Ion is released, and also penetrates cationic membrane
Into water chamber, total desorption rate is equal to the sum of electrode adsorption amount and work ion dosis neutralisata in adsorption process, liquid outlet to be processed electricity
Conductance rises because ion enters；When ion ingress rate reaches maximum, conductivity reaches highest；Later, with electrode by
It is gradually saturated, ion ingress rate reduces, and liquid outlet conductivity to be processed is gradually reduced；Until ion ingress rate is zero, wait locate
When reason liquid outlet conductivity reaches liquid initial conductivity to be processed, desorption process terminates.
5. according to a kind of polarized film electric adsorption system described in claim 1, it is characterised in that: the polarization-film electric adsorption device
For modularized design, multiple units are arranged according to processing task, the composition of each unit is respectively end plate or isolation from left to right
Frame is isolated in plate, electrode chamber, porous material electrode, and frame is isolated in anionic membrane, and frame is isolated in water chamber, and frame, electricity is isolated in cationic membrane
Pole room, porous material electrode, isolation board or end plate, one isolation board of adjacent two units shared；Wherein, end plate, isolation frame and every
It is acrylic material from plate, electrode chamber and water chamber are silica gel material, and anionic membrane is highly selective homogeneous ionic membrane；It is discharged side
Plate unilateral side top arranges that apopore, electrode chamber are frame structure, porous electrode material is placed in frame, upper end opening is drawn porous
Electrode material receiving electrode is simultaneously used for injecting and polarizing liquid, on frame it is diagonally arranged enter aquaporin hole and exhalant canal hole, isolation frame is diagonal
Be arranged into aquaporin hole and exhalant canal hole, anionic membrane and cationic membrane it is diagonally arranged enter aquaporin hole and exhalant canal
Hole, water chamber are frame structure, on frame it is diagonally arranged enter aquaporin hole and exhalant canal hole, and be connected into frame, enter aquaporin
It is only connected in water chamber realization with exhalant canal, water inlet side end plate unilateral side lower disposed blasthole.
