Abstract
The utility model discloses an improved ionic membrane electrolysis bath which comprises an ionic membrane, wherein a cathode and an anode are respectively bonded at two sides of the ionic membrane; the cathode comprises a cathode supporting net, an elastic net, a protecting net and an active coating surface net which are sequentially arranged; the active coating surface net is close to the ionic membrane; a polarization rectifier for preventing the active coating surface net from being damaged by a battery effect during shutdown is arranged on the cathode and is connected with a power supply. The improvement of zero polar distance is carried out on the ionic membrane electrolysis bath, so that the power consumption is decreased. In addition, the polarization rectifier is arranged, so that the active coating surface net of the cathode is prevented from being damaged by the battery effect during the shutdown.
Description
Technical field
The utility model relates to a kind of reworked ion-exchange membrane electrolyzer.
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 " battery effect " while parking, be reduced into the reaction of chlorion at anolyte compartment's generation chlorine atom, on negative electrode, there is the oxidation of metal simultaneously, make its corrosion, negative electrode one side of film is by nickel and iron pollution, membrane resistance increases, voltage raises and can produce damage by anticathode activated coating veil.
Utility model content
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of reworked ion-exchange membrane electrolyzer is provided, and adopts zero pole span to make power consumption low, and anticathode activated coating veil produces damage can prevent from stopping time.
For achieving the above object; the technical solution of the utility model has been to provide a kind of reworked ion-exchange membrane electrolyzer; 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; described negative electrode is provided with while parking and prevents the polarization rectifier of battery effect to the damage of activated coating veil, and described polarization rectifier is connected with power supply.
As preferably, described polarization rectifier is also connected with standby power supply.
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 polarization rectifier is set; can prevent from shutting down time, the anticathode activated coating veil of battery effect produces damage; by standby power supply is set, can in the time of power-off, meet an urgent need in addition.
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, polarization rectifier.
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 reworked 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 while parking and prevents the polarization rectifier 7 that battery effect damages activated coating veil 6, and described polarization rectifier 7 is connected with power supply.
As shown in Figure 1, described polarization rectifier 7 is also connected with standby power supply.When power supply is unstable or when instantaneous dead electricity, not power supply of polarization rectifier 7, now the activated coating veil 6 of negative electrode is more dangerous, by standby power supply is set, can play emergencing action, and effectively prolection coating veil 6 is injury-free.
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.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.
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.
