Customised Sodium Hypochlorite For Drinking Water Electrolysing Plant
Principle:
The revolutionary CNJS-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
Technical parameters:
| Type | Power(V/Hz) | concentration of liquid(mg/l) | available chlorine (Kg/h) | Flow (m3/h) | Salt consumption (kg/d) | Water consumption (m3/d) | Power consumption (kw) | Size(m) (l×w×h) |
| CNJS-L3000 | 380V/50Hz | 7-9 | 3 | 0.375 | 252 | 9 | 17.5 | 900*700*1780 |
Available chlorine: 7.0-9.0g/L ; Power input: 380V, 50Hz ;

| Other equipment framework will rust after three months and three years later, will affect the service life of equipment. CNJY equipment framework use alumina material, and does not rust |
| Space | Host machine size:1200*860*1950 | Host machine :2000*1000*2200 Control cabinet:850*700*1800 rectifier:500*1000*1100 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. |
