Abstract
The utility model discloses an apparatus for producing stannous sulfate by electrolysis which is provided with an electrolytic tank, an ion exchange film is used as the diaphragm of the electrolytic tank, and the electrolytic tank can form a plurality of anode chambers and cathode chambers by the adoption of the multiple electrode; the anode plate is the pure tin, and the sulfuric acid solution can generate stannous sulfate in the anode chamber after being electrolyzed. For the anion exchange film is used, the generation of the sponge tin on the cathode can be eliminated, and the quality of the product are improved. The current efficiency and the production benefit are improved, the cost is reduced, the operation and the management are easy, and the product quality of the product is stable.
Description
The utility model relates to a kind of production stannous sulfate (SnSO
4) device, particularly a kind of multiple-electrode ionic exchange embrane method electrolysis production SnSO
4Device.
Stannous sulfate is a kind of aluminum alloy surface treatment agent, also can be used for plating, analytical chemistry reagent, and its purposes is very extensive.Original production method is to adopt the diaphragm-free electrolysis method.Its shortcoming is to produce a large amount of extra large bright and beautiful tin in anode dissolution tin on the negative electrode.This not only causes waste of electric energy, and has also increased trouble on operational administrative, and the quality of product is wayward stable.Therefore, original production method has seriously limited further developing of producing.
The purpose of this utility model is in order to overcome above-mentioned defective, a kind of device that can eliminate the electrolysis production stannous sulfate of negative electrode Shanghai brocade tin generation to be provided.
For reaching this purpose, the utility model has adopted a kind of device of multiple-electrode ionic exchange embrane method electrolysis production stannous sulfate.This device is made up of the electrolyzer of producing stannous sulfate, in electrolyzer, closely be fixed with anion-exchange membrane more than one as barrier film, barrier film is divided into mutually isolated two non-leakage above separate slots with electrolyzer, respectively be placed with a positive plate or negative plate in each separate slot successively, make electrolyzer form anolyte compartment and cathode compartment in order like this.Positive plate and negative plate respectively are parallel to the positive and negative electrode of direct supply.Be marked with sulphuric acid soln in the electrolyzer as electrolytic solution, be equipped with the bottom switch and flow out stannous sulfate the anolyte compartment.
Compare with the device of existing production stannous sulfate, advantage is: one, because this device adopts is the multi-electrode membrane electrolysis, therefore eliminated the generation of negative electrode spongy tin, improved the quality and the output of product.Two, existing electrolyzer adopts series connection and hundreds of little electrolyzer productions in parallel.The utility model adopts some larger-size big electrolyzers, like this, produces the SnSO of same quantity
4The required time shortens greatly, has significantly improved productivity effect and current efficiency, has reduced production cost, and remarkable economic efficiency is arranged.
Below in conjunction with accompanying drawing the utility model is elaborated.
Fig. 1 is the work synoptic diagram of electrolysis production stannous sulfate.
Fig. 2 is the structural representation that the utility model is produced the stannous sulfate electrolyzer.
Among the figure, the 1st, electrolyzer, the 2nd, direct supply, the 3rd, positive plate, the 4th, negative plate, the 5th, anion-exchange membrane, the 6th, switch.
As can be seen from Figure, electrolytic cell 1 is by external direct current power supply 2 power supplies. Dc source 2 Can be a general AC/DC convertor, it be transformed to 380V or 220V alternating current The D.C. regulated power supply electrolysis uses. The required voltage of electrolysis production can be between 2-6V. Contain polylith positive plate 3 and polylith minus plate 4 in the electrolytic cell 1 of production stannous sulfate. Sun Separate with anion-exchange membrane 5 between the utmost point and the negative electrode, electrolytic cell 1 is divided into the anode chamber with cloudy Utmost point chamber, anode and negative electrode are connected respectively on the positive pole and negative pole of dc source. Anode tin Generate SnSO at anode chamber's electrochemical dissolution4Solution produces hydrogen on the negative electrode. Used Amberplex is anion-exchange membrane 5, it can effectively stop cation by film from The anode chamber enters utmost point chamber, and the characterisitic parameter of anion-exchange membrane 5 is: thickness is 0.15-0.23mm ion exchange capacity is 0.18-2.2 milliequivalents/gram dry film, water content is 2.2-2.8%, surface resistance is 4.5-8 Ω/cm2, transport number is) and 88%, bursting strength is 21. 5 * 105Pa。
Minus plate 4 materials tin sheet, positive plate 3 is pure tin. Anodic current density is 1-10A/dm2, tank voltage is 2-6 volts. Initial used for electrolyte 10-15% in the electrolytic cell 1 H2SO
4Solution does not stop to add in electrolytic process. Anolyte adopts flow method, anode The switch 6 of lower end, chamber flows out anolyte, its SnSO4Concentration is 15-25%. The anode that flows out Liquid vacuum evaporation, Crystallization Separation. Mother liquor is reused when electrolysis is prepared.
Electrolytic cell is welded with polyethylene board, and ion exchange membrane is every passing through the trough rim flange Use fastened by screw, prevented seepage. Cell dimension is bigger tens times than conventional sulculus, easily In operational administrative, keep constant product quality.
