LHB Sodium Hypochlorite Generator with Electrolytic Seawater
The sodium hypochlorite Generator with Electrolytic Seawater functions to produce highly active sodium hypochlorite solution by high-speed electrolysis of natural seawater. Following dehydrogenization and storage, the sodium hypochlorite is fed to dosing point as biocide to effectively kill microbes, oceanic creatures, algae and pathogens containing in the water body, so as to prevent the circulating water pipeline and condenser system from blockage.
Widely used inthe coastal power station circulating cooling water, chemical, petrochemical and offshore drilling platforms, desalination, ship ballast water treatment and other fields.
Principle of Work
The NaCl in Seawater or brine is used as electrolyte in the electrolytic chlorine system, through the DC current electrolysis to produce a certain concentration of sodium hypochlorite.
The basic reaction that takes place in an electrolytic cell
Anodic chlorine gas precipitation
Cathode hydrogen precipitation
In which Cl2 deposited on the anode is dissolved in the electrolyte to form HCl and HClO, the H2 precipitated on the cathode generates OH-. Because there is no septum between the cathode and anode, that is to complete the homogeneous secondary chemical reaction. The total reaction is：
