Abstract
The invention relates to a method for improving an ion film electrolyser by a film polar distance technology. The method comprises the following processes of: adding an elastic net with nickel based material on a cathode net of the ion film electrolyser; adding a covering net; and finally adding an active coating top net, wherein the active coating top net is made of weaved nickel net and a noble metal coating. Improved by the film polar distance technology, the cell voltage of a unit cell and the power consumption for producing caustic soda can be reduced greatly by 8%-10% in comparison with data at the starting state of an original device.
Description
(1) technical field
The present invention relates to a kind of ion-exchange membrane electrolyzer, especially relate to a kind of method of using the ion-exchange membrane electrolyzer of film pole span technological transformation.Belong to technical filed of chlor-alkali equipment.
(2) background technology
Ion-exchange membrane electrolyzer is the chlorine industry specific equipment, and its effect is to produce caustic soda (NaOH) and chlorine (cl by electrolytic brine (Nacl)
2) etc.Chlorine industry is as the high energy consumption industry, and save energy is raised the efficiency, and employing new technology energy-saving and cost-reducing with advanced and applicable technology is Eternal Theme.The early stage complex pole type ion-membrane appliance arrangement of operation is aging at present, and energy consumption is very high.Tracing it to its cause, is because present electrolysis with ion-exchange film slot device, main by ionic membrane and the anolyte compartment and the cathode compartment that are arranged at the ionic membrane both sides respectively form.As distance being arranged, about 2～3mm between the sun level net of electrode and the cathode screen.This can produce a volts lost.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of method that reduces the ion-exchange membrane electrolyzer of using the technological transformation of film pole span of volts lost is provided.
The object of the present invention is achieved like this: a kind of method of using the ion-exchange membrane electrolyzer of film pole span technological transformation, described method comprises following technological process: add the elastic network(s) of loading onto nickel-base material on the cathode screen of ion-exchange membrane electrolyzer earlier, add again and load onto nerve of a covering, add at last again and load onto the activated coating veil, described activated coating veil adds noble coatings by thin braiding nickel screen and makes.Make cathode screen and the distance between the anode network on the electric slot device reduce to film pole span (anode, negative electrode and ionic membrane three fit).
The invention has the beneficial effects as follows:
1, relatively is suitable for the upgrading of old ion-exchange membrane electrolyzer;
2, elastic network(s) elastomeric flexible, stressed even, can not damage ionic membrane;
3, the spacer screen of elastic network(s) and cathode screen, the contact area between the veil are big, and distribution of current is more even;
4, the cathode screen coating is a precious metal thermooxidizing coating, and smooth surface can not cause wearing and tearing to ionic membrane;
Through the improvement of film pole span technology of the present invention, the power consumption of unit groove bath voltage and production caustic soda can decline to a great extent, and the data when newly driving with original device are compared, and can descend 8%～10%.

Fig. 1 is the ion-exchange membrane electrolyzer structural representation of the inventive method preparation.
Reference numeral among the figure:
The elastic network(s) 5 of activated coating veil 1, anode network 2, ionic membrane 3, nerve of a covering 4, nickel-base material, cathode screen 6.
(5) embodiment
Referring to Fig. 1, Fig. 1 is the ion-exchange membrane electrolyzer structural representation of the inventive method preparation.As seen from Figure 1, the present invention's method of the ion-exchange membrane electrolyzer of film pole span technological transformation, described method comprises following technological process: add the elastic network(s) 5 of loading onto nickel-base material on former cathode screen 6 earlier, add again and load onto nerve of a covering 4, add at last again and load onto activated coating veil 1, described activated coating veil 1 adds noble coatings by thin braiding nickel screen and makes.
Claims (1)
1. method with the ion-exchange membrane electrolyzer of film pole span technological transformation, it is characterized in that described method comprises following technological process: on the cathode screen of ion-exchange membrane electrolyzer, add the elastic network(s) of loading onto nickel-base material earlier, add again and load onto nerve of a covering, add at last again and load onto the activated coating veil, described activated coating veil adds noble coatings by thin braiding nickel screen and makes.
