Abstract
The invention belongs to the technical field of electrochemistry and relates to a novel electrolytic tank which is used for producing weak alkaline drinking water by using an electrolytic method. The invention is characterized in that the negative electrode and the positive electrode in the electrolytic tank adopt two polar plates with different coating layers; wherein, the polar plate adopted on the positive electrode is a titanium plate coated with ruthenium, iridium or ruthenium-iridium alloy coating layer on the surface, and the negative electrode is produced by a polar plate which is a titanium plate coated with platinum or platinum alloy coating layer on the surface. The novel electrolytic tank overcomes the disadvantages that in the traditional electrolytic tank, both the negative electrode and the positive electrode adopt the polar plate which is a titanium plate coated with ruthenium, iridium or ruthenium-iridium alloy coating layer, the positive electrode is very easy to be corroded by lye, and the coating layer is easy to shed off, thus the quality of the produced drinking water is affected, the service life of the electrolytic tank is shortened, the electrochemical effect is weak, the producing efficiency of water is low and electrical consumption is high. Furthermore, the service life of the novel electrolytic tank is increased by about 30%. The coating layer is not shed off, the quality of the produced drinking water is guaranteed, the producing efficiency of the water is enhanced, the electrical consumption is reduced by about 10-20%, and the cost is lower by about 30% than that of the electrolytic tank with the negative electrode and the positive electrode being coated with platinum or platinum alloy.
Description
Technical field
The invention belongs to the technical field of electrochemistry electrolytic process and produce a kind of novel electrolytic bath in the alkalescent drinking water equipment.
Background technology
The pole plate of the cathode and anode in the tap water of the electrolysis legal system now electrolyzer is titanium plate surface coating ruthenium, iridium, platinum or its alloy.Adopt differing materials to make coated layer, the result of use of its cost of manufacture and pole plate and life-span are also inequality.The oxidation-resistance of platinum, resistance to acids and bases, electroconductibility, all has very big advantage with the bonding force of titanium plate.Therefore, all make electrolyzer abroad with this kind method.Its price is very expensive, causes the manufacturing cost of electrolyzer to increase substantially.Though the battery lead plate of making of ruthenium, iridium and alloy coated layer thereof also can satisfy service requirements, its electrochemistry, physical property are far away from being coated with platinum plating or platinum alloy coated layer.Yet the price of ruthenium, iridium can make the manufacturing cost of electrolyzer much lower far below platinum, so the battery lead plate domestic manufacturer of alkalescent drinking water electrolyzer all adopts this kind way now.
The pole plate of coating ruthenium, iridium or its alloy layer, because of its alkali resistance and with the bonding force of titanium plate a little less than, so when making negative electrode and using, be corroded easily, and coated layer also easily comes off.And the coated layer that comes off can be sneaked in the tap water.Reduced the alkalescent drinking water index.Another shortcoming is because its electroconductibility is relatively poor, and electrochemical effect is not really strong during electrolysis, makes system water efficient lower, and power consumption is bigger.
Summary of the invention
The present invention seeks to design a kind of novel electrolyte tank for preparing alkalescent drinking water using electrolytic method, for electrolytic process produce alkalescent drinking water equipment provide a kind of life-span longer, electrochemical effect is stronger, pole plate does not have the novel electrolytic bath that coated layer comes off.
Realize a kind of novel electrolyte tank for preparing alkalescent drinking water using electrolytic method of the object of the invention, it comprises cell body, negative plate and positive plate place respectively and are positioned at both sides in the cell body, barrier film is between negative plate and positive plate and over against the water-in at cell body top, negative electrode is drawn terminal stud and is connected with negative plate and is fixed on cell body top one side, anode is drawn terminal stud and is connected with positive plate and is fixed on the other side in cell body top, and acidic effluent mouth and alkaline water outlet lay respectively at the cell body both sides; And negative plate surface coated metal platinum or platinum alloy, positive plate surface coated metal ruthenium or iridium or both alloys.
This structure novel electrolytic bath also can make the multipole plate novel electrolytic bath of a plurality of anodes, a plurality of negative electrode cascaded structures.
The inventor is at the shortcoming of using coating ruthenium, iridium and alloy coated layer pole plate electrolyzer thereof to exist now, after deliberation, that test finds to produce the shortcoming negative electrode that pole plate is corroded and coated layer comes off is more serious and obvious than anode.Through strengthening experiment, cathode life is 1/2～2/3 of anode life, and the anode coated layer does not have obvious obscission.
For overcoming the shortcoming of coating ruthenium, iridium and alloy coated layer pole plate thereof, do the reinforcing life experiment to being coated with platinum plating or platinum alloy pole plate, its life-span improves more than 30% than coating ruthenium, iridium or its alloy pole plate, and does not have coated layer and come off.Employing is coated with platinum plating or the platinum alloy pole plate should be optimal selection.Yet increasing substantially of its cost can make device fabrication enterprise hang back again.The inventor ponders repeatedly, researchs and analyses experimental result, thinks that problem mainly occurs in negative electrode, and negative electrode is a side that produces alkaline water, as long as the negative electrode problem has been solved, bath life, drinking water quality is improved greatly.New electric tank cathode plate adopts and is coated with platinum plating or platinum alloy coated layer, and positive plate still adopts coating ruthenium, iridium or its alloy coated layer.The new electrolyzer of the pole plate of two kinds of different coated layers is made the water experiment repeatedly and the tap water inspection has all been reached intended purposes.
Because negative electrode has adopted and has been coated with the platinized electrode plate, its electroconductibility has improved.Electrolysis water process electrochemical effect has obtained reinforcement, and system water efficient improves, and it is about 10～20% that power consumption has reduced, and the corrosion of negative electrode alkali resistance improves greatly, the alkalescent drinking water of producing, and water quality improves.
Because an anticathode has adopted and is coated with platinum plating or platinum alloy electrode plate, so the cost of electrolyzer all adopts than cathode and anode and is coated with platinum plating or the platinum alloy pole plate reduces about 30%.
The invention of new electrolyzer had both solved the problem of coating ruthenium, iridium or the existence of its alloy pole plate electrolyzer now, had guaranteed that again manufacturing cost can significantly not improve.
The present invention has overcome now state's internal electrolysis and has produced that the yin, yang pole plate is titanium plate surface coating ruthenium, iridium or its alloy coated layer in the employed electrolyzer of alkalescent drinking water.Bonding force between its alkali resistance of the pole plate of this coated layer, electroconductibility and coated layer and titanium plate is all poor, has caused negative plate easily to be corroded.Coated layer easily comes off, and the tap water of producing is polluted.Work-ing life of electrolyzer is short, and the electrolytic process electrochemical effect a little less than, system water efficient is lower, power consumption is bigger.And the situation of positive plate will be got well much than negative electrode.The present invention well overcomes above-mentioned shortcoming, is coated with platinum plating or platinum alloy coated layer pole plate is made negative electrode, and its alkali resistance corrodibility is fine.No coated layer comes off, its good conductivity, system water efficient height, power consumption reduce, and electrolyzer prolongs work-ing life.
