Customised Sodium Hypochlorite For Drinking Water Electrolysing Plant

?

?

Principle:

?

? ?The revolutionary CNJY-L series sodium hypochlorite generator is a newly and for on-site product of NaClO equipment and use for all kinds of needed NaClO disinfected. Its working principle is :the sodium chloride solution under the certain voltage effect of the cell, a series of electrochemical reaction within the cell and the resulting solution is the NaClO solution. The main process can be simplified as follows:

?

? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? Electrode reaction:

anode:2Cl--2e→Cl2

cathode:2H++2e→H2

Solution:2NaOH+Cl2→NaCl+NaClO+H2O

Host machine , Control cabinet , rectifier can not put in one rom together , need anther device room | saving space Easy to install and operate |
Raw material | refined salt or Industrial salt | refined salt | A wide scope of utility, economy and low operating cost |
Inlet water requirements | Depend on actual situation need a water softener or not | ?indispensable a water softener | Can reduce unnecessary link,? increase equipment safety. |
Brine concentration | Salt brine mixing device, fully dissolved, ensure the stability of brine concentration. | No mixing device, brine concentration is not stable. | The stable liquid concentration,extend equipment service life. |
Dilute brine ratio | ?water injector ratio | ?normal valve | High accuracy, more safety |
Generator fixed way | All moulds are fixed, equipment installation is more stable | With simple metal ring, need to reinforce the equipment | |
Structure of electrode slices | Bipolar type, in series, big gap, large flux | Bipolar type,small gap, small flux | Big flux , easy to control temperature equipment,electrode service long life |
Thickness of electrodes | 2mm | 1.5mm | Long life of electrode, resistance to deformation, not short-circuited. |
Electrode coating technology | nano- coated up to 20 ruthenium iridium oxide particles , coating thickness of 2- microns , 25 times of coating can ensure positive side high produ ing and long life | Normal ruthenium iridium thickness thin, easy to deformation. | Coating adhesion, long service life |
Electrode gap | Big gap and flux | Small gap and flux | Low temperature big flux? equipment, high efficiency. |
