Description
Technical field
This utility model belongs to technical field of water treatment equipment, and more particularly to electrolytic saltwater makes hypochlorite disinfectant
A kind of saline electrolysis groove based on anodic protection used by liquid.
Background technology
It is a major trend of current water treatment field to be carried out disinfection using liquor natrii hypochloritises, it is adaptable to scene system
Standby, the hypochlorite generator for directly adding is the indispensable sterilizing equipment decontaminating apparatuss of many water factories.Sodium hypochlorite is being prepared using electrolysis
Electrolysis bath must be used during solution, heat is inevitably produced during electrolytic saltwater, due to preparing
Tap water is used during saline solution, and tap water contains calcium ions and magnesium ions, therefore incrustation scale, plate can be produced during being electrolysed
Knot is on pole plate.Gathering for incrustation scale causes the efficiency of electrolysis bath to be gradually reduced, and has a strong impact on electrolysis effectiveness.
The method of scale removal body is gone mainly there are two kinds at present, first method is regular pickling descaling, this method needs to tear open
Electrolysis bath is unloaded, is taken out during electrode is placed on weakly acidic solution and is soaked scale removal, or weakly acidic solution immersion is injected in electrolysis bath and removed
Dirt.This scale removal mode complex operation, and professional training is had to pass through, many little water factories and rural area water station do not possess this energy
Power, therefore limit the use of hypochlorite generator.Second method is to configure the tap water early stage used by weak brine
Carry out sofening treatment.This mode can reduce calcium ions and magnesium ions quantity to a certain extent, but can increase cost；And soften
Water needs regeneration, uses consumption salt amount high；When softening resin regeneration, its exchange capacity is gradually decaying, so its
Regeneration period constantly will be adjusted；As this mode can not completely avoid fouling, in general softened water will coordinate
The scale removal of falling pole is together using；But the service life of electrode is inherently damaged in pole.
Therefore, how to prevent incrustation scale fouling on pole plate from being saline electrolysis groove urgent problem.
The content of the invention
The purpose of this utility model is to overcome the shortcomings of to provide a kind of based on anodic protection existing for prior art
Saline electrolysis groove.
Find after carefully analyzing the formation of incrustation scale that incrustation scale is all hardened on cathode plate.Cell reaction on pole plate is
Chloride ion near anode in solution loses the sodium ion for electronically forming chlorine and forming positive monovalence, and the hydrion near negative electrode is obtained
To electronically forming hydrogen and generating the hydroxyl of negative one valency, then chlorine generates sodium hypochlorite with sodium hydroxide reaction.
Anode：2Cl--2e→Cl2；
Negative electrode：2H++2e→H2；
Solution reaction：2NaOH+Cl2→NaCl+NaClO+H2O。
But in solution also containing positive bivalence calcium ions and magnesium ions, is easily combined with the hydroxyl of negative one valency generate calcium hydroxide
And magnesium hydrate precipitate.As the hydroxyl of negative one valency is formed about in negative electrode, so precipitate is easier in negative electrode pole
Plate gathers hardened so as to form incrustation scale.Based on principles above, this utility model is, on the basis of original positive and negative electrode pair, then to increase
Plus a shield electrode, and shield electrode is connected to into power cathode so that the current potential of shield electrode is not more than original sun
The current potential of pole pole plate and cathode plate；So that precipitate is more prone to molding is separated out in shield electrode, greatly reduce
Formation of the precipitate in the negative plates of original electrode.Therefore, it is possible to reach the original plate of protection and cathode plate
Effect.Shield electrode periodically extract out and clear up just can formation of the incrustation scale in negative plates is not reduced in the case of pole,
Keep the efficiency of electrolysis bath.The advantage that simultaneously pole is not brought is the rush of current that electrode avoids positive and negative pole, it is to avoid electricity
Pole figure layer is because the peeling caused by rush of current.
And the operating of falling pole is that plate is used as negative electrode, and cathode plate is used as anode, anode pole now
Plate will produce evolving hydrogen reaction.Electrode is by made by Titanium base coating ruthenium iridium oxide, wherein primarily serving electro-catalysis in itself
What is acted on is the iridium of positive tetravalence；But the hydrogen that evolving hydrogen reaction is produced has very strong reproducibility so that the iridium of the positive tetravalence of script
The iridium of positive bivalence is reduced into, the broken electrocatalysises for having changed iridium, while can also cause iridium to become fragile peeling.Therefore pole is to sacrifice
Electrode life carries out scale removal for cost.
This utility model can avoid the application of the existing program of falling pole, from root using the scheme for increasing a shield electrode
Extend the service life of electrode in sheet.
The technical solution of the utility model is：A kind of saline electrolysis groove based on anodic protection, including electrolyte, electrolysis
Groove, power supply and electrode, the electrode are removably sealed in electrolyte bath, electrolysis bath be provided with electrolyte entrance and
Electrolyte outlet, the positive pole of the power supply are connected to the anode tap of electrolysis bath, and the negative pole of the power supply is connected to the moon of electrolysis bath
Extremely；It is characterized in that：Also include detachable protective electrode, anode tap one of the detachable protective electrode from electrolysis bath
Side is inserted into the anode tap insulated enclosure of the inside of electrolysis bath, the detachable protective electrode and electrolysis bath；It is described detachable
Shield electrode be connected with the negative electrode of power supply, cathode terminal of the electrolyte entrance in electrolysis bath, the electrolyte outlet is in electricity
The anode tap of solution groove.
Electrolyte is to flow to anode tap from cathode terminal, therefore the temperature of electrolyte is cathode terminal to electricity from electrolyte entrance
Solution liquid outlet is that anode tap gradually rises.Shield electrode is arranged on into electrolyte high-temperature area and is conducive to more preferable shield electrode.
Detachable protective electrode is changed for convenience, and preferred technical scheme is：The electrolysis bath is shaped as cylinder
Shape, being shaped as the detachable protective electrode are bar-shaped.The electrolyte bath is provided with support detachable protective electrode
Bracing frame, the detachable protective electrode be inserted into the length in electrolysis bath not less than electrolysis slot length half.
In order to meet the requirement for anticorrosion of electrolysis bath, the material of the electrolysis bath is PVC or engineering plastics or polyethylene.
In view of electrolytic efficiency of the galvanic electrolytic efficiency higher than alternating current, further, the power supply is DC source,
The scope of the output voltage of the power supply is DC6-15V；The scope of the output current of the power supply is 10-100A.
For reduces cost, detachable protective electrode is reused；The detachable protective electrode is limited further
Material be rustless steel, or the basic material of the detachable protective electrode is titanium, and the surface-coated of the Titanium base has
The coating of metal Ru iridium oxide or metal platinum.
Its remarkable advantage is this utility model compared with prior art：Incrustation scale is caused to exist using the method for shield electrode
Formed on detachable protective electrode, so as to protect the electrode of script.Pole is avoided down, the service life of electrode is extended.
