Introduction
Sodium hypochlorite (NaClO) generators are increasingly used in water treatment plants due to their safety, efficiency, and reliability. Unlike traditional chlorine gas or commercial sodium hypochlorite solutions, on-site generation offers multiple benefits.
Key advantages include:
1、Safe raw materials – Only salt and electricity required
2、Advanced hydrogen management – Prevents accumulation risks
3、 Electrical safety – Low-voltage DC operation
4、 Multi-stage hydrogen removal – Ensures storage tank safety
5、Hydrogen detection system – Real-time monitoring and alarms
6、 Odor-free operation – Sealed system with exhaust control
Now, let’s explore each benefit in detail.
1. Safe and Easily Available Raw Materials
Why is raw material safety important?
Traditional chlorine gas is hazardous to store and also transport. Meanwhile, commercial sodium hypochlorite degrades over time. In contrast, on-site generators use only:
Salt (NaCl) – Easily available, non-hazardous
Electricity – Low-voltage DC power
How does it work?
The generator electrolyzes a saltwater solution, producing sodium hypochlorite on demand.
Benefits:
1. No dangerous chemicals – Eliminates risks of chlorine gas leaks
2. Fresh disinfectant – Higher efficacy than stored commercial solutions
3. Cost-effective – Salt is cheap and widely available
2. Advanced Device Structure with Hydrogen Separator
Why is hydrogen a concern?
During electrolysis, hydrogen gas (H₂) is produced:
Solution: Inter-electrode Hydrogen Separator
Immediate H₂ removal – Prevents gas buildup in the electrolyzer at the same time
Maintains efficiency – Reduces electrical resistance caused by gas bubbles
Enhances safety – Minimizes explosion risks at the same time
Key features:
Automatic venting – Continuous release of hydrogen
Pressure stabilization – Prevents overpressure in the cell at the same time
3. Electrical Safety (Low-Voltage DC System)
Why is electrical safety crucial?
High-voltage systems pose electrocution risks. Our generator uses:
Low-voltage DC power – Safe for operators
Insulated connections – Prevents accidental contact at the same time
Grounding protection – Reduces electrical hazards at the same time
Additional protections:
Circuit breakers – Prevent overloads
Waterproof enclosures – Suitable for wet environments
4. Multi-Stage Hydrogen Removal from Storage Tanks
Problem: Residual H₂ can accumulate in solution tanks.
Solution: Forced Ventilation System
High-capacity exhaust fan – Removes trapped hydrogen
Dilution to safe levels – Discharges H₂ at <0.5% concentration at the same time
Explosion-proof design – Flame arrestors & lightning protection at the same time
How it works:
Electrolyzer vents most H₂
Storage tank fan extracts residual gas
Piped to outdoor release point
5. Hydrogen Detection & Emergency Response
Safety failsafes include:
H₂ sensors – Installed at ceiling level (H₂ rises)
Alarm at 0.25% concentration – Early warning
Auto-shutdown at 0.4% – Prevents dangerous buildup at the same time
Emergency ventilation – Activates exhaust fans
Why this matters:
Prevents explosions – H₂ is explosive at 4% concentration
Protects workers – Immediate hazard response at the same time
6. Odor-Free Operation (Sealed System)
Traditional problems:
Airtight storage tanks – No fumes escape
Dual exhaust fans (redundant) – Ensures continuous ventilation at the same time
Negative pressure design – Prevents leaks at the same time
Backup systems:
Airflow sensors – Detect fan failures
Auto-switch to backup fan – No interruption
FAQ
Q1: What happens during a power outage?
A: The system shuts down safely, and H₂ detectors remain active if backup power exists.
Q2: How long does the generated NaClO last?
A: Freshly made, it’s stable for days to weeks (vs. commercial solutions degrading faster).
Q3: Can this replace chlorine gas completely?
A: Yes! Many plants have switched due to safety and ease of use.
