1 Product Overview
The marine dedicated seawater electrolysis chlorine generation system is a special on-site disinfection and anti-fouling equipment developed for offshore platforms, marine engineering and ship water systems. Different from traditional salt-based electrolysis equipment, this system directly utilizes natural raw seawater for electrolytic reaction, realizing zero manual chemical addition. It continuously generates low-concentration high-activity sodium hypochlorite disinfectant, which is mainly used for sterilization, algae removal and marine organism inhibition of marine circulating cooling water. The whole machine adopts marine anti-corrosion and shock-resistant design, resisting seawater salt spray corrosion and harsh wave vibration working conditions. With high automation and low maintenance features, it is the standard anti-fouling and disinfection equipment for global offshore marine engineering projects.
2 Technical Principle
This system adopts direct seawater electrolysis low-frequency constant-current technology, utilizing natural sodium chloride contained in seawater as the raw material. After precision filtration to remove suspended sediments and marine impurities, raw seawater is stably delivered into special seawater electrolytic cells. Under stable DC electric field, directional electrochemical reaction occurs: chloride ions in seawater are oxidized to generate chlorine gas, which instantly reacts with water to form high-activity sodium hypochlorite solution. The generated disinfectant is directly dosed into the marine circulating water pipeline to inhibit microbial and barnacle reproduction. By intelligently adjusting current density and water flow rate, the system maintains stable residual chlorine concentration, realizing continuous and efficient anti-fouling and disinfection. Electrolysis by-products are safe and environmentally friendly without secondary pollution to the marine environment.
3 Main Features
Pure Seawater Direct Electrolysis: No salt, fresh water or chemical additives required, directly using raw seawater for on-site chlorine generation, saving operating costs greatly.
Marine Anti-Corrosion & Shock Resistance: Adopts high-grade titanium alloy and marine anti-salt-spray materials, resisting seawater corrosion and marine vibration, suitable for harsh offshore working conditions.
Intelligent Unattended Operation: Automatic water intake, electrolysis and dosing design, supporting long-term 24-hour continuous operation with automatic fault alarm.
Precise Residual Chlorine Control: Linked with residual chlorine sensors to dynamically adjust electrolysis power, ensuring stable disinfection effect and avoiding excessive chlorine residue.
Eco-Friendly Marine Protection: Natural electrolysis reaction with no chemical residue, compliant with international marine environmental protection discharge standards.
4 Core Advantages
Working Condition Adaptability Advantage: Exclusive seawater direct electrolysis technology solves the pain points of traditional equipment’s inability to adapt to high-salinity seawater and easy scaling, perfectly matching offshore marine engineering scenarios.
Ultra-Low Operating Cost: Zero consumable input except electric energy, eliminating repeated procurement, transportation and storage costs of disinfectants and industrial salt.
Stable Anti-Fouling Effect: Real-time generation of fresh active disinfectant completely inhibits algae growth and marine organism adhesion, effectively preventing pipeline blockage and heat exchange efficiency decline.
High Operational Safety: On-site real-time chlorine generation with no storage of hazardous chemicals, eliminating leakage and safety risks of liquid chlorine and bottled disinfectants.
Low Maintenance & Long Service Life: Optimized anti-scaling electrode structure reduces electrolytic cell scaling, with long electrode service life and simple daily maintenance.
5 Core Components
Special Seawater Electrolytic Cell: Core reaction component with anti-scaling and anti-corrosion coating, specially designed for high-salinity seawater electrolysis, ensuring high electrolysis efficiency and stable operation.
Marine Grade Intelligent Rectifier: Provides stable constant current and constant voltage power, adapts to offshore grid fluctuation, and guarantees consistent electrolysis effect.
Seawater Precision Filtration Unit: Filters marine sediments, suspended solids and biological impurities to protect the electrolytic cell from blockage and damage.
Marine Anti-Corrosion PLC Control Cabinet: Realizes full-process automatic control, data monitoring and fault self-diagnosis, adapting to high salt spray marine environment.
Residual Chlorine Linked Dosing Device: Dynamically adjusts dosing volume according to water quality changes to maintain optimal disinfection and anti-fouling status.
