The electrolytic seawater sodium hypochlorite generator uses natural seawater as input and adopts high-speed electrolysis to prepare high-activity sodium hypochlorite solution on site. The sodium hypochlorite solution dosing point as a biocide through dehydrogenation storage, effectively kill microorganisms, sea creatures, algae, and crustaceans in the water body, and preventing the blockage of circulating water pipelines and condenser systems.
The main reaction process
NaCl+ H2O = NaClO + H2↑
Electrode reaction: anode: 2Cl--2e- → Cl2 cathode: 2H2O + 2e- → H2 + OH-
Solution reaction: 2NaOH + Cl2 → NaCl + NaClO + H2O

System composition:

Seawater booster pump set	The seawater booster pump set provides the power source for the seawater filter and the back-end process to overcome the pressure drop.
Seawater filtration system	Filter seawater to micron level to prevent large particles from entering the electrolytic cell group and affecting the electrolysis process.
Electrolyzer group	The electrolytic cell group is the core unit of the whole set of equipment. The electrolytic cell group adopts titanium-based ruthenium and iridium rare metal oxide coating. The seawater passes through the electrolytic cell group through direct current catalysis to convert seawater's sodium chloride into sodium hypochlorite and hydrogen.
Rectifier transformer	Usually a rectifier transformer in the form of a silicon controlled rectifier is used, the voltage is changed to the required voltage through the transformer, and then a thyristor is used for controlled rectification. The input AC power is converted into DC power and the positive and negative poles provide power source and output to the electrolytic cell.
Storage and dehydrogenation tank	The generated sodium hypochlorite solution and hydrogen enter the storage and dehydrogenation tank through the pipeline for temporary storage and dehydrogenation process.
Dehydrogenation fan unit	The wind unit generally adopts the 1D+1S form, which blows a large amount of air into the storage and dehydrogenation storage tank to dilute the produced hydrogen and provides a power source to discharge the diluted hydrogen to a safe discharge point.
Dosing pump set	Use corrosion-resistant centrifugal pump to output to the dosing point.
Pickling system	The raw material is diluted with 31% hydrochloric acid and used for acid washing of the temporary storage power supply solution tank group to remove the scale of the electrolytic tank group.
Control System	The central control system of the complete set of equipment is used to control the automatic start and stop of the complete set of equipment and coordinated control with the outside.
Power distribution system	Allocate power sources for motors and related electrical drive equipment.
Optional accessories	The default standard configuration of PPE electrolyzer 1. Mesh type electrolyzer (MESH) 2. Concentric circular tube electrolyzer (CTE)
