Ozone treatment technology in EBR electron beam irradiation process: Why is it necessary to effectively decompose ozone?

High concentrations of ozone are continuously produced during EBR processes. Direct discharge not only endangers personnel health and equipment lifespan but also violates environmental regulations. By installing a dedicated ozone destruction system synchronized with EBR equipment, ozone can be safely decomposed into oxygen, ensuring continuous production while meeting environmental standards.

How Ozone Is Generated in EBR Processes

During EBR operation, high-energy electrons interact with oxygen molecules in the air. Oxygen molecules (O₂) absorb energy, dissociate into reactive oxygen atoms, which then combine with O₂ to form ozone (O₃). This electron-induced chemical reaction depends on electron energy, airflow, and operating time. In continuous industrial production, ozone generation is unavoidable and cannot be safely dissipated without treatment.

Why Ozone Cannot Be Directly Discharged

Ozone in the upper atmosphere protects against UV radiation, but at ground level it is a pollutant.

Impact on Human Health

Ozone is highly irritant. Exposure to high concentrations can cause respiratory irritation, coughing, chest tightness, and long-term occupational health risks.

Environmental Impact

Ozone is a key component of photochemical smog. Uncontrolled release can degrade air quality and create regulatory compliance issues.

Potential Damage to Equipment and Materials

Ozone is a strong oxidizer. Long-term exposure can cause:

• Accelerated rubber aging
• Seal cracking
• Metal corrosion
• Shortened lifespan of electrical components

Ozone control is thus critical not only for compliance but also for equipment reliability.

Principle of Ozone Destruction Systems

The core function of an ozone destruction system is to convert ozone into oxygen before discharge:

O₃ → O₂

Components typically include:

• Ozone decomposition unit
• Induced draft fan
• Piping system
• Control system
• Safety monitoring system

Ozone is collected, decomposed, and finally released in a safe form.

Why Ozone Destruction Systems Must Be Interlocked with EBR Equipment

Ozone generation is synchronous with EBR operation. If the destruction system stops while EBR continues, ozone will accumulate rapidly. Industrial systems require synchronized startup, shutdown, fault interlocks, and status feedback to prevent leaks.

Future Trends in Ozone Management Systems

• Higher decomposition efficiency
• Lower energy consumption
• Intelligent monitoring
• Remote operation and maintenance
• Automatic fault diagnosis

Future systems will emphasize not only regulatory compliance but also operational efficiency and lifecycle cost management.
