Abstract
The utility model discloses an electrolytic apparatus which generates sodium hypochlorite by electrolyzing salt solution and which is suitable for the treatment of sewage containing bacteria, the treatment of electroplated cyanide containing waste and the sterilization of drinking water. The utility model is characterized in that the anode is a cylindrical reticular metallic anode with double-face work; the cathodes are cylindrical metallic cathodes; the anode is positioned between the two cathodes. The utility model has high electrolytic productivity, easy scale removal, cleanness, stable performance, simple operation and low cost.
Description
The utility model is applicable to a kind of negative electrode commutation scale removal monoblock type bieletrolysis device of the water generates clorox that electrolyzes table salt.
When the hypochlorite generator works, to produce the oxyhydroxide settling of metal ions such as calcium magnesium on the negative electrode of electrolyzer, this settling is deposited on cathode surface, not only influence anodic electroconductibility, and can cause short circuit between the yin, yang when serious, consequently increase the power consumption of producing clorox and the productive rate that reduces clorox.The method that solves cathode deposit has at present: (1) adopts the cyclic electrolysis mode, and the salt solution that circulates by high speed washes away cathode surface, prevents that deposition from taking place; (2) through hydrochloric acid soaking and washing commonly used, dissolving has been deposited on the settling on the negative electrode; (3) adopt negative electrode commutation scale removal, promptly in electrolyzer, increase an auxiliary cathode, when needs are removed the main cathode surface deposits, the main cathode commutation is anode, auxiliary cathode just can make its lip-deep settling dissolving remove as negative electrode when main cathode uses as anode.Method (3) is easy to operate, and the Japan clear 51-41030 of special permission communique adopted this method.
This communique introduction is bar-shaped with anode, and electrode form is a single stage type.The electrolyzer of this structure has following deficiency in practicality: because each point is different with the cathode plane interpolar on the anode section, then cathode and anode electric force lines distribution inequality causes anode section local location current density concentrated loads excessive, and anode damages easily.Because bar-shaped anode diameter is big, cathode plane is covered partly greatly during negative electrode commutation scale removal, and scale removal is difficult for thoroughly.In addition,, require the electrolysis direct current electric power outputting current big, cause direct supply cost height owing to be the single-stage electrolyzer.
The purpose of this utility model is to avoid above-mentioned deficiency of the prior art and a kind of employing net metal anodic electrode commutation scale removal monoblock type twin-stage electrolyzer is provided.
The purpose of this utility model reaches by following measure, in each grade tank room, form negative electrode commutation scale removal electrolyzer by main cathode, auxiliary cathode, anode, sealing member, insulating component, the anode of this electrolyzer tank room (1) is the netted double-face working metal anode of round shape, negative electrode (2), (3) are the cylindrical metal negative electrode, the electrode concentric sets of each grade tank room lumps together, and anode is between two negative electrodes; Two its structure formations of tank room like this are identical and fit together, constitute an integral body symmetrically.Separate with a dead ring (4) between two outer cathodes, two inner cathodes are separated with the dead ring (5) that flange is arranged on the surface, an outer garden and by screw thread it are linked into an integrated entity, the flange antianode is spacing, it between outer cathode electrolyte passage, the inside of inner cathode leads to water coolant, one annular recesses (6) is arranged in the end cap of electrolyzer (7), and to hold settling and the uniformly distributing electrolytic solution under removing, content of the present utility model is referring to Fig. 1.This electrolyzer leads to little galvanic current protection negative electrode between anode and negative electrode when non-electrolysis work and non-negative electrode commutation scale removal avoids corrosion.
Solution of the present utility model can further specify.
Anode can be the titanium base to be coated with ruthenium iridium metals electrode also can be other metal anodes such as titanium base plating plumbic oxide, the titanium-matrix electrode matrix can process with the titanium net, also can form with titanium pipe bit hole.Negative electrode can be other metal electrode of stainless steel or intercropping anode use in short-term.
Outer cathode insulation stripper loop (4) in the device, inner cathode insulation stripper loop (5), end cap (7), insulation stripper loop (8) can be made of the material of anti-salt and clorox corrodibility and better physical strength.
Device required little electric current of galvanic protection when non-electrolysis work and non-negative electrode commutation scale removal can be supplied with by store battery or D.C. regulated power supply.
