Abstract
The utility model discloses a zero polar distance ionic membrane electrolyzer which comprises an ionic membrane, wherein a negative pole and a positive pole are adhered to both sides of the ionic membrane respectively; the negative pole comprises a negative pole support net, an elastic net, a protection net and an active coating surface net which are sequentially arranged; the active coating surface net is close to the ionic membrane; the negative pole is provided with a precipitation device which is used for precipitating redundant iron ions and a discharge device which is used for discharging the precipitated iron ions. The zero polar distance ionic membrane electrolyzer disclosed by the utility model reduces the electricity consumption by carrying out zero polar distance reformation on the ionic membrane electrolyzer, and ensures the property of the negative pole by controlling the content of the iron ions through the precipitation device and the discharge device.
Description
Technical field
The utility model relates to a kind of zero polar distance ion membrane electrolysis bath.
Background technology
Current industrial alkaline is that use table salt water is raw material substantially, adopting ion-exchange membrane electrolyzer to carry out electrolysis makes, according to understanding, between anion membrane electrolytic tank electrode, need the spacing that keeps certain, the electrolysis of the too small electrolytic solution of spacing is insufficient, but interelectrode electrolytic solution can be because electric current generates heat by the electricresistance effect producing, cause this part of electric energy to be wasted, in addition the ion-exchange membrane electrolyzer of implementing zero pole span transformation is because catholyte system iron ion content is when too high, iron ion can be deposited in cathode surface and cover activated coating veil, causes cathode performance to decline.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of zero polar distance ion membrane electrolysis bath is provided, and adopts zero pole span to make power consumption low, and by separating out device and discharger control iron ion content, guarantees cathode performance.
For achieving the above object; the technical solution of the utility model has been to provide a kind of zero polar distance ion membrane electrolysis bath; comprise ionic membrane; the both sides of described ionic membrane are fitted with respectively negative electrode and positive electrode; described negative electrode comprises the cathode support net, elastic network(s), catch net and the activated coating veil that set gradually; described activated coating veil is pressed close to described ionic membrane, and described negative electrode is provided with the discharger of separating out device and the iron ion of separating out being discharged of unnecessary Iron pick up.
As preferably, described negative electrode is also provided with the proofing unit for detection of iron ion content, and described proofing unit is separated out device and described discharger is connected with described.
As preferably, on described activated coating veil and described anode, be on average provided with the tetrafluoroethylene spacer bar that described ionic membrane is fixed.
As preferably, described anode is venetian blind type anode.
As preferably, described anode side is provided with strengthens baffle plate and the overflow weir of liquid at electrolyzer internal recycle.
Advantage of the present utility model and beneficial effect are: by ion-exchange membrane electrolyzer being carried out to zero pole span transformation, reduce power consumption, in addition by separating out device and discharger control iron ion content, guarantee cathode performance.
Accompanying drawing explanation
Fig. 1 is schematic diagram of the present utility model.
Wherein: 1, ionic membrane; 2, anode; 3, cathode support net; 4, elastic network(s); 5, catch net; 6, activated coating veil; 7, separate out device; 8, discharger.
Embodiment
Below in conjunction with drawings and Examples, embodiment of the present utility model is further described.Following examples are only for the technical solution of the utility model is more clearly described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1; a kind of zero pole span ionic membrane 1 electrolyzer; comprise ionic membrane 1; the both sides of described ionic membrane 1 are fitted with respectively negative electrode and positive electrode 2; described negative electrode comprises the cathode support net 3, elastic network(s) 4, catch net 5 and the activated coating veil 6 that set gradually; described activated coating veil 6 is pressed close to described ionic membrane 1, and described negative electrode is provided with the discharger 8 of separating out device 7 and the iron ion of separating out being discharged of unnecessary Iron pick up.
As shown in Figure 1, described negative electrode is also provided with the proofing unit for detection of iron ion content, and described proofing unit is separated out device 7 and described discharger 8 is connected with described.
As shown in Figure 1, on described activated coating veil 6 and described anode 2, be on average provided with the tetrafluoroethylene spacer bar that described ionic membrane 1 is fixed.
As shown in Figure 1, described anode 2 is venetian blind type anode 2, and described anode 2 sides are provided with strengthens baffle plate and the overflow weir of liquid at electrolyzer internal recycle.
In the present embodiment; catch net 5 is woven by metal wire; prevent elastic network(s) 4; cathode support net 3 comes off; elastic network(s) 4 is worked out by metal wire; make it possess certain elastic screen product by machine printed bending, activated coating veil 6 is processed by the establishment of pure nickel wire rod, and at its surface-coated activated coating.
Principle of work: in the time that proofing unit detects that iron ion content in catholyte system exceedes 1PPm, its control is separated out device 7 by unnecessary Iron pick up, then, by discharger 8, the iron ion of separating out being discharged, can guarantee that negative electrode is energy then.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of the utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
