brief introduction

Catalytic Recuperative Oxidizers (CO) utilize catalysts, whether precious metals or common metal oxides, to lower the activation energy required for the reaction between organic compounds in Volatile Organic Compounds (VOCs) and O2. This enables the full oxidation of organic substances at lower temperatures, resulting in flameless combustion. The high-temperature oxidized gas is then discharged after indirect heat exchange with incoming exhaust gas through a heat exchanger, achieving a heat utilization rate typically exceeding 75%. This technology is commonly employed to treat highly concentrated exhaust gas from the regeneration and desorption of adsorbents.

theory:

Before entering Catalytic Recuperative Oxidizers (CO), there is typically a heat exchanger to preheat gas containing Volatile Organic Compounds (VOCs). The preheated gas enters Catalytic Recuperative Oxidizers (CO) and is elevated to the working temperature of the catalyst. An exothermic reaction occurs as pollutants are converted into carbon dioxide and water vapor. Subsequently, the clean hot flue gas passes through the heat exchanger, transferring thermal energy to the preheated incoming air, and is then discharged into the atmosphere through a chimney.
By using catalysts with different oxidation temperatures, the inlet temperature is usually lower, ranging from 250-305°C. Heat is released during the oxidation reaction in the catalytic bed, causing the temperature in the oxidation chamber to rise, for example, reaching 300°C, depending on the concentration and calorific value of VOCs. Due to the lower inlet temperature, less energy is required to maintain the oxidation temperature, resulting in corresponding energy savings

characteristic

1. Lowering the ignition temperature, achieving higher purification efficiency, and optimizing heat exchange and heating efficiency lead to reduced energy consumption and overall lower operating costs.
2. The compact equipment layout structure not only saves on construction and installation expenses but also ensures convenient operation and maintenance management.
3. RuiDing employs a well-established waste heat recovery system, maximizing the recuperation of waste heat. This approach allows for normal production processes without the need for additional fuel, generating superheated high-temperature steam and yielding substantial economic benefits.
4. The utilization of a rectangular catalytic reactor by RuiDing enhances convenience in catalyst loading, replacement, installation, and maintenance procedures.
5. RuiDing's design of Catalytic Recuperative Oxidizers (CO) incorporates catalysts such as palladium and platinum stainless steel metal honeycomb. These catalysts exhibit high activity, excellent high-temperature stability (up to 730 ℃), superior mechanical strength, an extended lifespan (up to 4-5 years), reduced resistance and pressure, and ease of cleaning. This design is adaptable to a wide range of characteristics.
