Advantages of catalytic combustion
2021-10-03
Do you know the advantages of catalytic combustion methods? Let Tangshan Lantian Aoyu Technology Co., Ltd. tell you that catalytic combustion equipment mainly uses catalysts to change the reaction conditions to achieve the removal of organic matter under lower conditions. The essence of the gas-solid catalytic reaction generated in the catalytic combustion equipment is the deep oxidation effect of active oxygen species. In the process of catalytic purification, catalysts are used to reduce the activation energy of chemical reactions, making the reaction conditions more favorable for the conditions that can be controlled. By utilizing the effect of a catalyst, the exhaust gas undergoes flameless incineration at lower ignition temperatures, and is oxidized and decomposed into C02 and H20, releasing a large amount of heat energy to remove harmful substances from the exhaust gas.
Catalytic combustion equipment is a type of equipment used to treat organic waste gas. Catalytic combustion equipment is customized based on the air flow rate. Different enterprises have different exhaust gas flow rates, and the equipment used is also different. Depending on the concentration of the exhaust gas, the desorption time also varies. The desorption process of activated carbon in catalytic combustion equipment is online. When the activated carbon adsorption is saturated, the equipment will automatically desorb the activated carbon. When the activated carbon is desorbed, it will undergo three suction and one desorption or four suction and one desorption based on the number of boxes. This means that not all the boxes are desorbed during the desorption process. As long as one box is desorbed, the other boxes are still operating. This will not affect the operation of the factory.
What are the advantages of catalytic combustion methods
1. High exhaust gas purification rate, up to over 95%, high heat recovery rate, safety: low temperature response, equipped with fire suppression system, alarm equipment and other protective measures.
2. No secondary pollution, no secondary pollutants such as nitrogen oxides are generated, and the process does not cause secondary pollution.
3. Automated control, low energy consumption, simple operation, automatic alarm in case of problems, low consumption, energy-saving, and long service life: high-temperature stainless steel edge wrapping, anti-corrosion and durable, and long catalyst service life.
4. Low operating cost RCO generally eliminates the need for auxiliary heating in the heating chamber of the purification equipment when the organic waste gas reaches a specific concentration (above 1000mg/m3), saving costs.
5. Heat recovery rate: Heat recovery efficiency ≥ 95%.
What are the advantages of catalytic combustion methods
1. The principle, data, and function of this equipment are stable, easy to operate, safe and reliable, energy-saving and labor-saving, without secondary pollution. The equipment occupies a small area and is lightweight. The adsorption bed adopts a drawer type structure, which is easy to fill and replace.
2. Choosing new activated carbon adsorption materials, honeycomb activated carbon has superior kinetic functions compared to granular activated carbon, and is extremely suitable for use under high air volume.
3. The catalytic combustion chamber uses precious metal catalysts supported by honeycomb ceramics, which have low resistance and high activity. When the concentration of organic waste gas reaches above 2000ppm, it can maintain spontaneous combustion.
4. Low power consumption, as the bed resistance is small, can be achieved by using a low-pressure fan, which not only consumes less electricity but also has low noise. The power of the exhaust fan is shown in the attached table.
5. During catalytic combustion, electric heating is required for starting. After the catalytic combustion of organic compounds begins, their incineration heat energy is sufficient to maintain the required temperature for reaction. At this moment, the electric heating stops automatically, and the starting electric heating time is about 1 hour. The required power for starting is shown in the attached table.
