VOC Treatment Technology: Regenerative Catalytic Oxidation (RCO) Equipment

Thermal-storage catalytic combustion is a novel exhaust-gas purification technology. Building upon catalytic oxidation and regenerative thermal oxidation (RTO), it incorporates a series of energy-saving designs and advanced materials, thereby evolving into a state-of-the-art method for treating organic waste gases. At temperatures ranging from 250°C to 400°C, the waste gas passes over a catalyst that oxidizes its organic pollutants into harmless carbon dioxide and water, achieving effective purification. This technology offers significant advantages, including high heat recovery efficiency, zero secondary pollution, low energy consumption, enhanced safety, and long service life.

 VOC Treatment Technology: Regenerative Catalytic Oxidation (RCO) Equipment

Working principle:

Organic waste gas is drawn into the oxidation furnace by a blower and heated by fuel combustion to a temperature of approximately 250–300°C. At this temperature, the organic components in the waste gas are oxidized and decomposed into carbon dioxide and water under the action of a catalyst. Subsequently, the high-temperature flue gas resulting from the reaction enters a specially designed ceramic heat-storage unit, where more than 95% of the heat is absorbed. After the gas temperature drops to near the inlet temperature, it is discharged through the chimney, thereby achieving the purpose of purifying the waste gas. Meanwhile, the heat absorbed by the heat-storage unit is used to preheat the subsequent waste gas stream, which helps reduce the reaction temperature and minimize consumable material usage.

High efficiency: high exhaust gas purification rate, exceeding 95%, and high heat recovery rate.

Safety: Low-temperature reaction, equipped with flame-arresting systems, alarm devices, and other protective measures.

No secondary pollution: No nitrogen oxides or other secondary pollutants are generated, and the entire process is free from secondary pollution.

Automated control and low energy consumption: simple operation, automatic fault alarm, and energy-efficient.

Long service life: high-temperature stainless steel edging for corrosion resistance and durability, ensuring a long catalyst lifespan.

Applicable Industries : Exhaust gas treatment for drying production lines in industries such as paint, rubber, coatings, plastic products, printing inks, and petrochemicals, as well as exhaust gas treatment for painting and baking processes in manufacturing plants for automobiles, shipbuilding, container production, and household appliances.
