Hypochlorite generator, during saline electrolysis, can occur Cl at anode and negative electrode-—2e→Cl2, H2O+2e=
H2+OH-, when stopping electric current, electrode has stopped electrolysis, but still has Cl in liquor natrii hypochloritis-/Cl2, H2+OH/H2O
Electronics to pure, can constitute galvanic interaction, form reverse current.I.e. Cl2+2e→2Cl-, H2+2OH-→H2O.During power failure, secondary
The electric current that electrolytic solution in sodium chlorate generator produces, can make the negative electrode of battery lead plate do positive pole, and anode does negative pole.This is reverse
Although electric current is little, but the ruthenium oxide coatings in electrode coating is had harm greatly, it is possible to cause coming off of electrode coating.
Summary of the invention
In view of the problem existing for prior art, the present invention provides a kind of sodium hypochlorite with polarization fairing to occur
Device, arranges commutator and polarization commutator simultaneously, utilizes polarization commutator, to one forward current the least of electrolytic solution, and can

Detailed description of the invention
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
Non-for limiting the scope of the present invention.
Being described principle and the feature of the present invention below in conjunction with accompanying drawing, example is served only for explaining the present invention, and
Non-for limiting the scope of the present invention.
As it is shown in figure 1, a kind of hypochlorite generator, including commutator 1, polarization commutator 2 and electrolysis bath 3；Described whole
Stream device 1, polarization commutator 2 are connected by circuit in parallel；Circuit after described commutator 1 and polarization commutator 2 parallel connection and electrolysis
Groove 3 electrically connects, and for powering electrolysis bath 3, is provided with the electrode assembly for electrolyte in described electrolysis bath.Described electrode
Device is battery lead plate, and described battery lead plate is connected by wire with electrolysis bath 3.Control for convenience, electrolysis bath 3 and polarization commutator
2 circuit connected are provided with switch.The circuit that electrolysis bath 3 is connected with commutator 1 is provided with switch.
As shown in Figure 1B, for there being the electrolysis bath divided of both positive and negative polarity, the electrolysis bath of the most non-pole, described commutator is just
Pole is connected with the positive electrical of polarization commutator, and the negative pole of described commutator is connected with the negative electricity of polarization commutator.Commutator
Positive pole is connected with the positive pole of electrolysis bath after the positive pole parallel connection of polarization commutator again, and the negative pole of commutator is negative with polarization commutator
Extremely after parallel connection, negative pole with electrolysis bath is connected again.
For can the electrolysis bath of pole, both positive and negative polarity all can use, and therefore, there is no special restriction when connecting.
As in figure 2 it is shown, in the case of normal work, the generation of typically no reverse current, polarization commutator can not
Devote oneself to work.When rectifier current reduces to 0 when, electrolyte produces reverse current, the direction of reverse current as it is shown on figure 3,
Now, polarization commutator starts to devote oneself to work, and the electric current that polarization commutator produces is for offsetting the reverse current that electrolyte produces.
Concrete principle and operating process are referred to explained below:
After being full of solution (such as: electrolyte) in electrolysis bath 3, electrolyte will produce electromotive force (i.e. galvanic element electricity
Pressure), close the switch of the circuit being connected with the commutator 2 that polarizes, make polarization commutator 2 devote oneself to work, the voltage of output is opened from zero
Till beginning to rise to the voltage that voltage is slightly above galvanic element generation, such that it is able to offset galvanic element voltage or electric current, improve whole dress
The service life put.
When hypochlorite generator plans stopping or fault stops, polarization commutator can put into, in advance with rectification
Device parallel operation, the electric current of its output is started from scratch and is raised to setting value.When commutator does not has electric current, bearing of polarization commutator work
Lotus just can offset the reverse current that the electrolyte in hypochlorite generator produces.
When preparing liquor natrii hypochloritis, the saline of suitable concn can be selected as electrolyte according to practical situation.Example
As: when using without septum electrode, brine strength is 4% (mass fraction)；When using ionic membrane method, brine strength is 24-
26% (mass fraction).
Hypochlorite generator of the present invention, by arranging commutator and polarization commutator, the polarization of configuration simultaneously
Commutator, can avoid producing in electrolyte galvanic interaction, i.e. reverse current, destroy the condition that galvano-cautery produces, thus protect
The coating of the battery lead plate protecting hypochlorite generator is corroded, to improve the service life of the electrode in hypochlorite generator.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all spirit in the present invention and
Within principle, any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
