12% Sodium Hypochlorite Generator for Marine Biofouling Prevention Equipment
1. Product Overview
Industrial circulating water dedicated high concentration sodium hypochlorite generator is heavy-duty electrolytic disinfection equipment for large flow industrial cooling water systems in coastal areas. Different from low-concentration household and municipal water disinfection equipment, this unit uses saturated refined brine as raw material to produce high-titer sodium hypochlorite stock solution, which can be diluted on demand for pipeline continuous dosing. Coastal circulating water contains massive marine plankton, shellfish larvae and algae, which easily attach to heat exchange tubes and cause pipeline scaling, water flow reduction and unit energy consumption rise. The equipment realizes on-site continuous production of high-concentration disinfectant without storing bulk hazardous hypochlorite barrels, with strong salt-fog corrosion resistance, stable output under fluctuating water temperature and water volume, perfectly matching the long-term continuous operation demands of power plants, coastal chemical factories and large industrial parks.
2. Technical Principle
The system adopts high-load saturated brine intensified electrolysis technology. Industrial refined salt and softened water are automatically stirred and filtered to form saturated pure brine without impurity particles. The concentrated brine flows into MMO coated titanium reinforced electrolytic cells with enlarged reaction area. Under high-power constant DC electrolysis, chloride ions conduct sufficient electrochemical reaction to generate high-concentration sodium hypochlorite stock solution with 8-12% available chlorine. The PLC control system collects real-time circulating water flow, pipeline residual chlorine and seawater temperature data to automatically adjust electrolysis power and dosing frequency. Concentrated NaClO liquid is transported to dosing points and mixed evenly into cooling water pipelines, high active chlorine destroys marine organism cell walls and inhibits spore incubation to achieve long-term anti-biofouling effect. Excess hydrogen generated during electrolysis is collected and safely exhausted through closed ventilation pipeline to eliminate explosion risks.
3. Main Features
High Titer Stable Output: Produce 8%-12% high-concentration hypochlorite stock liquid, less dosing volume, reduce pipeline conveying workload
Full Marine Anti-Corrosion Configuration: Electrolytic cell, pipeline and liquid tank adopt titanium alloy and FRP, resist coastal salt fog and chloride corrosion
Residual Chlorine Interlock Intelligent Control: Link with online residual chlorine sensor, automatic adjust production volume to avoid insufficient or excessive chlorine
Closed Hydrogen Safe Discharge System: Totally sealed electrolysis cavity, centralized hydrogen collection and dilution exhaust, meet industrial safety standards
Modular Expandable Design: Multiple electrolytic cell groups can be combined to match 10000-100000m³/h large circulating water flow
4. Core Advantages
Low Comprehensive Operating Cost: High concentration liquid reduces daily salt consumption and delivery pipeline investment, save over 35% chemical cost compared with buying finished hypochlorite
No Hazardous Chemical Storage Risk: On-site real-time production, no large-area storage of corrosive high-concentration disinfectant, simplify factory safety management
Strong Adaptability to Harsh Coastal Environment: Waterproof, dustproof and salt-fog proof cabinet, can run stably outdoors without special workshop construction
Long Electrode Service Life: Thickened MMO coating titanium electrolytic cell, anti-scaling structure, electrode maintenance cycle extended to 2 years
-
Stable Long-Term Anti-Fouling Effect: Freshly generated high-activity chlorine avoids disinfectant decomposition failure during long-distance transportation
5. Core Components
