Raw Material Pretreatment
Core Electrolysis Reaction
- At the anode (mostly ruthenium/iridium-coated titanium anode, chlorine corrosion-resistant), Cl- is preferentially discharged to generate chlorine gas (2Cl- - 2e- → Cl2↑);
- At the cathode, water molecules gain electrons to produce hydrogen gas (H2) and hydroxide ions (OH-). The OH- combines with Na+ in the solution to form sodium hydroxide (NaOH).
Sodium Hypochlorite Formation
I. Core Output Performance: Key Indicators Determining Disinfection Efficacy
Output performance represents the core capability of the equipment, directly related to the alignment with disinfection requirements. It mainly includes the following indicators:
1. Available Chlorine Production
Definition: The mass of "available chlorine" generated by the equipment per unit time (available chlorine is the standard for measuring the disinfection capacity of sodium hypochlorite, with a conversion ratio of 1g available chlorine ≈ 1.5g sodium hypochlorite);
Typical Range: Classified by capacity-small-scale equipment (50-500g/h), medium-scale equipment (500g/h-5kg/h), and large-scale equipment (5-50kg/h). Customization is available based on scenarios (e.g., swimming pools, water treatment plants, sewage treatment plants);
Key Requirement: The fluctuation error of production shall be ≤ ±5% (relying on a stable power supply and brine feed system).
2. Available Chlorine Concentration
Definition: The mass fraction of available chlorine in the generated sodium hypochlorite solution;
Typical Range: 0.8%-1.5% (i.e., 8000-15000mg/L). Excessively high concentration tends to cause ClO- decomposition, while excessively low concentration requires increased dosage;
Control Logic: Precise control is achieved by adjusting brine concentration (2%-3%) and electrolysis current density, with a concentration error of ≤ ±0.1%.
3. Current Efficiency
Definition: The ratio of the electric quantity actually used for generating available chlorine to the total consumed electric quantity, reflecting the energy utilization efficiency of the electrolysis process;
Industry Standard: ≥ 85% (high-quality equipment can reach over 90%);
Influencing Factors:
Electrode material (ruthenium/iridium-coated titanium anodes offer higher efficiency);
Brine purity (impurities reduce current efficiency);
Electrolysis temperature (the optimal efficiency range is 20-40ºC).

II. Key Operating Parameters: Fundamental Indicators for Ensuring Equipment Stability
Operating parameters determine the equipment's energy consumption level and long-term reliability, and must comply with industrial-grade operation standards:
1. Power Supply Parameters
Input Power: Typically 380V/220V AC (three-phase/single-phase), compatible with industrial or civil power supply;
Output Characteristics: DC voltage-stabilized/current-stabilized output, with a current adjustment range of 5-500A and a voltage adjustment range of 5-50V, supporting stepless adjustment based on production requirements;
Energy Consumption Indicator: Energy consumption per unit of available chlorine ≤ 6kWh/kg (advanced equipment can be as low as 4.5kWh/kg); lower energy consumption results in lower long-term operating costs.
2. Brine Consumption
Theoretical Consumption: Approximately 2.5-3kg of industrial salt (purity ≥ 99.5%) is required to generate 1kg of available chlorine;
Practical Requirement: Brine consumption error ≤ ±10% (a precise brine metering pump must be matched to avoid salt waste or insufficient concentration).
3. Electrolysis Temperature Control
Operating Temperature: The temperature inside the electrolytic cell must be controlled within 20-40ºC (temperature < 20ºC will increase solution resistance and energy consumption; temperature > 40ºC will accelerate ClO- decomposition);
Temperature Control Method: Small-scale equipment adopts natural heat dissipation, while medium/large-scale equipment requires a supporting air-cooling or water-cooling system, with a temperature fluctuation ≤ ±3ºC.

III. Safety Performance: Core Guarantee for Avoiding Operational Risks
The equipment involves electrolytic reactions and flammable/explosive by-products (H2), so its safety performance must comply with relevant national standards (e.g., GB 50831-2012 Technical Requirements for Chlorine Production by Seawater Electrolysis):
1. Hydrogen (H2) Handling
Emission Requirements: H2 generated at the cathode must be collected through a dedicated pipeline. The vent port should be far from ignition sources and in a well-ventilated area, and the emission concentration must be lower than the lower explosive limit of hydrogen (4%);
Safety Design: Equipped with an H2 concentration detector (which triggers automatic shutdown when the concentration exceeds the standard) and a one-way valve (to prevent air backflow).
2. Corrosion Protection and Insulation
Material Requirements: Components in contact with the electrolyte, such as electrolytic cells, brine tanks, and pipelines, must be made of corrosion-resistant materials (e.g., PVC, PE, titanium alloy) to prevent sodium hypochlorite from becoming ineffective or causing corrosion leakage due to contact with metals;
Electrical Insulation: The equipment enclosure must have a protection rating of ≥ IP54 (dustproof and waterproof), and the insulation resistance of the electrical system must be ≥ 10MΩ to prevent electric leakage risks.
3. Fault Protection
Protection Functions: Equipped with overcurrent protection (shuts down when current exceeds the standard), overvoltage protection (cuts off power when voltage is abnormal), liquid level protection (shuts down when brine/product liquid level is too low), and temperature protection (triggers an alarm when temperature exceeds 40ºC), ensuring safe shutdown of the equipment in case of abnormalities.
