1 Product Overview
The high concentration sodium hypochlorite generator is a professional industrial electrolysis disinfection device developed for scenarios requiring high-efficiency and high-strength water sterilization. Based on industrial brine electrolysis principle, the equipment uses refined salt and tap water as raw materials to continuously produce high-concentration sodium hypochlorite disinfectant through electrochemical reaction. Compared with conventional low-concentration NaClO generators, this upgraded model achieves higher available chlorine concentration, stronger oxidizing and bactericidal capacity, and better stability of finished disinfectant.
This on-site disinfection system completely replaces the traditional mode of purchasing bottled or barreled sodium hypochlorite. It realizes real-time preparation and on-demand dosing, avoiding disinfectant failure, concentration attenuation and safety hazards during transportation and storage. With industrial continuous operation capability, high anti-corrosion performance and intelligent automatic control, the equipment is widely applicable for advanced disinfection treatment of industrial wastewater, municipal tap water, reclaimed water, industrial circulating water and special process water in chemical, power and environmental protection industries.
2 Technical Principle
The high concentration sodium hypochlorite generator adopts intensified constant-current brine electrolysis technology with optimized electrode structure and current density control. The whole working process is fully closed and automatically controlled without manual chemical addition.
Firstly, refined salt and raw water are automatically proportioned and dissolved into saturated dilute brine, which is filtered precisely to remove impurities. The qualified brine is stably delivered into the high-efficiency electrolytic cell. Under the action of stable DC current, directional electrochemical reaction occurs: chloride ions are oxidized into chlorine gas at the anode, while water molecules are reduced at the cathode to generate hydrogen and hydroxide ions. Chlorine gas instantly reacts with hydroxide ions to synthesize high-concentration sodium hypochlorite solution. By optimizing electrolysis temperature, current density and liquid flow rate, the system effectively improves brine conversion rate and increases effective chlorine concentration. The by-product hydrogen is diluted and exhausted through a safe ventilation system to ensure intrinsically safe operation, realizing continuous and stable production of high-strength NaClO disinfectant.
3 Main Features
High Concentration & Strong Sterilization: Optimized intensified electrolysis structure greatly improves effective chlorine content. The generated high-strength sodium hypochlorite has powerful oxidation, algae removal and bactericidal effects, which can quickly kill bacteria, viruses and microbial spores in water.
Stable Disinfectant Performance: The on-site real-time preparation mode avoids concentration attenuation and invalidation of stored commercial disinfectants. The produced NaClO solution has uniform components and stable activity, ensuring consistent disinfection effect all year round.
Fully Automatic Intelligent Operation: Equipped with automatic salt dissolving, water inlet control, constant current electrolysis and automatic dosing functions. It supports 24-hour unattended continuous operation and automatic adjustment according to water flow and water quality changes.
High Safety & Low Risk: On-site on-demand production requires no large-scale storage of high-risk chemical disinfectants. Equipped with hydrogen dilution exhaust, overcurrent protection, overheating protection and leakage alarm devices, the equipment achieves zero safety hazards in operation.
Strong Corrosion Resistance & Long Service Life: The electrolytic cell and key contact parts are made of high-grade titanium alloy and special anti-corrosion materials, adapting to long-term high-intensity electrolysis working conditions with low failure rate and durable performance.
Green & Environmental Protection: Raw materials are only refined salt and water, no chemical additives. The reaction by-products are safe and controllable, no secondary pollution, meeting international environmental protection production standards.
4 Core Advantages
High-Efficiency Electrolysis Advantage: Adopting upgraded intensified electrolysis technology and optimized electrode gap design, the brine electrolysis conversion rate is significantly improved. The equipment produces higher concentration disinfectant with lower energy consumption, realizing energy-saving and high-yield operation.
Cost-Saving Economic Advantage: On-site self-production replaces purchased commercial disinfectants, greatly reducing long-term procurement, transportation and storage costs. Intelligent precise dosing avoids chemical waste and lowers overall water treatment operating costs.
Quality Stability Advantage: Different from purchased sodium hypochlorite which is prone to decomposition and concentration reduction, the generator produces fresh high-activity disinfectant in real time, ensuring stable and compliant water quality disinfection standards for a long time.
Industrial Adaptability Advantage: High-concentration disinfectant is suitable for high-pollution, high-microbial-load water bodies that ordinary low-concentration equipment cannot handle. It adapts to complex working conditions such as industrial heavy wastewater and high-temperature circulating water.
Intelligent Management Advantage: Support remote monitoring, data recording, fault self-diagnosis and operation parameter adjustment. It can be seamlessly connected with factory SCADA systems to realize intelligent centralized management of water treatment disinfection links.
5 Core Components
High-Efficiency Anti-Corrosion Electrolytic Cell: The core component of the equipment, made of high-purity titanium substrate with special noble metal coating. It features high current efficiency, strong corrosion resistance and long service life, supporting long-term high-concentration electrolysis reaction.
Intelligent DC Rectifier Power Supply: Provides stable constant current and constant voltage power for electrolysis. It automatically adjusts power according to water quality and flow changes, ensures consistent electrolysis efficiency and effectively avoids power fluctuation impact.
Automatic Salt Dissolving & Brine Proportioning System: Includes salt dissolving tank, precision filter and flow meter, realizing automatic raw water feeding, quantitative salt dissolving and precise brine proportioning to ensure stable brine concentration entering the electrolytic cell.
PLC Intelligent Control Cabinet: The central control unit of the whole system, responsible for equipment start-stop, parameter adjustment, automatic dosing, fault alarm and data statistics, realizing full-process unattended intelligent operation.
Automatic Dosing & Flow Feedback Device: Cooperates with water flow and residual chlorine sensors to dynamically adjust NaClO dosage, ensuring precise disinfection and avoiding excessive chlorine or insufficient sterilization.
Safe Hydrogen Dilution & Exhaust System: Dilutes and discharges the trace hydrogen generated by electrolysis in real time to prevent gas accumulation, ensuring intrinsically safe operation of the equipment in closed workshops.
