Catalytic combustion treatment is widely used in the purification of harmful organic waste gases emitted from workshops in industries such as petroleum, chemical, rubber, coating, and printing. Organic waste gases such as benzene, alcohols, and ethers can all be purified. The device has a complete system design, complete supporting equipment, high purification efficiency, and high degree of automation. It can effectively purify the workshop environment, eliminate pollution, improve working conditions, ensure the health of workers, and solve secondary pollution. It is most suitable for organic waste gases with low concentrations (50-1000ppm) and low economic value for recycling, and it is not advisable to use adsorption recycling treatment, especially for high air volume treatment scenarios. The characteristics of processing high air volume and low concentration exhaust gas include secondary waste heat recovery when the concentration is slightly higher, greatly reducing production and operation costs.

Technical principle of catalytic combustion RCO exhaust gas treatment equipment

This purification device is designed based on two basic principles: adsorption (high efficiency) and catalytic combustion (energy saving), namely adsorption concentration catalytic combustion method. The device adopts dual gas path continuous operation, and two or more adsorption beds can be alternately used. A catalytic combustion chamber first adsorbs organic waste gas with activated carbon, stops the adsorption operation when it reaches saturation, and then uses a hot gas flow to desorb organic matter from the activated carbon for regeneration; The detached organic matter has been concentrated (with a concentration several tens of times higher than before) and sent to the catalytic combustion chamber for catalytic conversion into CO2 and H2O for discharge.

Advantages of Catalytic Combustion RCO Exhaust Gas Treatment Equipment

Almost all waste gases containing organic compounds can be treated; Can handle organic waste gases with high air volume and low concentration; The elasticity of treating organic waste gas flow is high (nominal flow rate 20%~120%); Can adapt to changes and fluctuations in the composition and concentration of VOCs in organic waste gas; Not sensitive to small amounts of dust and solid particles carried in exhaust gas. 1. Adopting a combination process of adsorption concentration and catalytic combustion. The entire system has achieved a closed cycle of purification and desorption processes. Compared with organic waste gas purification devices for recycling, it does not require additional energy sources such as compressed air, and does not generate secondary pollution during operation. The equipment investment and operating costs are low.

2. The device has advanced design principles, unique materials, stable performance, easy operation, safety and reliability, energy saving and labor-saving, and no secondary pollution.

3. The equipment occupies a small area.

4. The catalytic combustion chamber adopts precious metal catalysts with ceramic honeycomb bodies, which have low resistance and high activity. When the concentration of organic vapor reaches over 2000PPm, spontaneous combustion can be maintained.

5. Low power consumption. Due to the low bed resistance, a low-pressure fan can be used. Before catalytic combustion of organic matter, electric heating needs to be started. When the organic matter starts catalytic combustion in the catalytic bed, its combustion heat is sufficient to maintain the temperature required for the reaction. At this time, the electric heating stops on its own, and the starting time for electric heating is about 1 hour.

6. The activated carbon bed that adsorbs organic waste gas can be used to desorb and regenerate the waste gas after catalytic combustion. The desorbed gas is then sent to the catalytic combustion chamber for purification without the need for external energy, with low operating costs and significant energy-saving effects.

7. Adopting a microcomputer centralized control system, the equipment operation and operation process are fully automated, ensuring safe, stable, and reliable operation.
