Product Description


Regenerative Thermal Oxidizer

Compared with traditional catalytic combustion, direct thermal oxidizer, RTO has the merits of high heating efficiency, low operation cost, and the ability to treat large flux low concentration waste gas. When VOCs concentration is high, secondary heat recycle can be realized, which will greatly reduce the operation cost. Because RTO can preheat the waste gas by levels through ceramic heat accumulator, which could make the waste gas to be completely heated and cracked with no dead corner(treatment efficiency>99%),which reduce the NOX in the Exhausting gas, if the VOC density >1500mg/Nm3, when the waste gas reach cracking area, it has been heated up to cracking temperature by heat accumulator, the burner will be closed under this condition.

RTO can be devided into chamber type and rotary type according to difference operation mode. Rotary type RTO has advantages in system pressure, temperature stability, investment amount, etc

Can regenerative thermal oxidizers be used for treating industrial wastewater?

No, regenerative thermal oxidizers (RTOs) are not typically used for treating industrial wastewater. RTOs are specifically designed for air pollution control and the treatment of gaseous pollutants, such as volatile organic compounds (VOCs) and hazardous air pollutants (HAPs).

Here are some key points to consider regarding the use of RTOs for treating industrial wastewater:

  • Operating Principle: RTOs rely on the combustion of pollutants in the gas phase. They utilize high temperatures to thermally oxidize gaseous pollutants, converting them into carbon dioxide and water vapor. However, wastewater treatment involves the removal or transformation of contaminants dissolved or suspended in water, which requires different treatment mechanisms.
  • Wastewater Treatment Technologies: Wastewater treatment typically involves processes such as physical separation, chemical treatment, biological treatment, and other specialized techniques depending on the nature of the contaminants. Common wastewater treatment technologies include activated sludge systems, sedimentation tanks, chemical precipitation, filtration, and various other methods tailored to specific wastewater characteristics.
  • Environmental Regulations: Industrial wastewater treatment is subject to stringent environmental regulations and discharge standards that govern the quality of effluent released into water bodies. Compliance with these regulations requires the implementation of appropriate wastewater treatment technologies specifically designed for the removal or reduction of contaminants in water, rather than air pollution control technologies like RTOs.
  • Integration with Wastewater Treatment Systems: While RTOs are not used for wastewater treatment, they may be integrated into overall industrial process systems where wastewater treatment is also required. In such cases, separate wastewater treatment technologies are employed to treat the wastewater, and RTOs are used to address air emissions resulting from the wastewater treatment process or other industrial operations.

In summary, regenerative thermal oxidizers are not suitable for treating industrial wastewater. They are designed for air pollution control and the destruction of gaseous pollutants. For effective wastewater treatment, industries should employ appropriate wastewater treatment technologies specifically designed for the removal or transformation of contaminants in water.

Are regenerative thermal oxidizers safe to operate?

Regenerative thermal oxidizers (RTOs) are designed with safety considerations to ensure their safe operation. When properly installed, operated, and maintained, RTOs provide a high level of safety. Here are some key points regarding the safety of operating RTOs:

  • Combustion and Fire Safety: RTOs are designed to safely combust and destroy volatile organic compounds (VOCs) and other pollutants in the exhaust stream. They incorporate various safety features to prevent the risk of uncontrolled fires or explosions. These features may include flame arrestors, temperature sensors, pressure relief devices, and automated shutdown systems to ensure safe operation in the event of abnormal operating conditions.
  • Control and Monitoring Systems: RTOs are equipped with advanced control and monitoring systems that continuously monitor various parameters such as temperature, pressure, and flow rates. These systems provide real-time data to operators, allowing them to detect any deviations from normal operating conditions promptly. Alarms and safety interlocks are often included to alert operators and initiate appropriate actions in case of abnormal situations.
  • Heat Recovery and Thermal Efficiency: RTOs are designed to maximize thermal efficiency by recovering and reusing heat generated during the oxidization process. This reduces the overall energy consumption and minimizes the risk of heat buildup within the system, contributing to safe operation and preventing excessive temperatures that could pose safety hazards.
  • Equipment and Material Selection: RTOs are constructed using materials that can withstand the high temperatures and corrosive conditions encountered during operation. Heat-resistant materials, such as ceramic beds or metallic heat exchangers, are commonly used. Proper material selection ensures the integrity and longevity of the equipment, reducing the risk of failures or leaks that could compromise safety.
  • Compliance with Standards and Regulations: RTOs must comply with applicable safety standards and regulations. These standards define specific requirements for the design, installation, operation, and maintenance of air pollution control systems, including RTOs. Compliance with these standards ensures that the RTOs meet the necessary safety criteria and helps safeguard the health and well-being of personnel and the surrounding environment.
  • Operator Training and Maintenance: Adequate operator training and regular maintenance are crucial for safe RTO operation. Operators should receive comprehensive training on the system’s operation, safety procedures, and emergency response protocols. Additionally, routine maintenance and inspections help identify and address any potential safety concerns or equipment issues before they escalate.

While RTOs are generally safe to operate, it is essential to follow the manufacturer’s guidelines, maintain proper safety protocols, and adhere to applicable regulations to ensure safe and reliable operation.

regenerative thermal oxidizers

What is a regenerative thermal oxidizer?

A regenerative thermal oxidizer (RTO) is an advanced air pollution control device used in industrial applications to remove volatile organic compounds (VOCs), hazardous air pollutants (HAPs), and other airborne contaminants from exhaust gases. It operates by using high temperatures to thermally decompose or oxidize the pollutants, converting them into less harmful byproducts.

How does a regenerative thermal oxidizer work?

An RTO consists of several key components and operates through a cyclical process:

1. Inlet Plenum: The exhaust gases containing pollutants enter the RTO through the inlet plenum.

2. Heat Exchanger Beds: The RTO contains multiple heat exchanger beds filled with heat storage media, typically ceramic materials or structured packing. The heat exchanger beds are arranged in pairs.

3. Flow Control Valves: Flow control valves direct the airflow and control the direction of the exhaust gases through the RTO.

4. Combustion Chamber: The exhaust gases, now directed into the combustion chamber, are heated to a high temperature, typically between 1400°F (760°C) and 1600°F (870°C). This temperature range ensures effective thermal oxidation of the pollutants.

5. VOC Destruction: The high temperature in the combustion chamber causes the VOCs and other contaminants to react with oxygen, resulting in their thermal decomposition or oxidation. This process breaks down the pollutants into water vapor, carbon dioxide, and other harmless gases.

6. Heat Recovery: The hot, purified gases leaving the combustion chamber pass through the outlet plenum and flow through the heat exchanger beds that are in the opposite phase of operation. The heat storage media in the beds absorb heat from the outgoing gases, which preheats the incoming exhaust gases.

7. Cycle Switching: After a specific time interval, the flow control valves switch the airflow direction, allowing the heat exchanger beds that were preheating the incoming gases to now receive the hot gases from the combustion chamber. The cycle then repeats, ensuring continuous and efficient operation.

Advantages of regenerative thermal oxidizers:

RTOs offer several advantages in industrial air pollution control:

1. High Efficiency: RTOs can achieve high destruction efficiencies, typically above 95%, effectively removing a wide range of pollutants.

2. Energy Recovery: The heat recovery mechanism in RTOs allows for significant energy savings. The preheating of incoming gases reduces the fuel consumption required for combustion, making RTOs energy-efficient.

3. Cost-effectiveness: Although the initial capital investment for an RTO can be significant, the long-term operational cost savings through energy recovery and high destruction efficiencies make it a cost-effective solution over the lifespan of the system.

4. Environmental Compliance: RTOs are designed to meet stringent emissions regulations and help industries comply with air quality standards and permits.

5. Versatility: RTOs can handle a wide range of process exhaust volumes and pollutant concentrations, making them suitable for various industrial applications.

Overall, regenerative thermal oxidizers are highly efficient and effective air pollution control devices widely used in industries to minimize emissions and ensure environmental compliance.
