RCO Catalytic Combustion Technology (Application Scope) RCO catalytic combustion technology is widely applied in the treatment of organic waste gases from a variety of industries such as painting, printing, spraying, electronics, plastics, rubber, enameled wire, machinery, motors, chemical industry, instrumentation, automobiles, engines, electrical appliances, and so on. The treatment efficiency can reach as high as 95%. One-time investment, comprehensive service, and worry-free EIA! Working Principle of RCO Catalytic Combustion Equipment Catalytic combustion equipment mainly consists of a flame arrester, a heat exchanger, a catalytic reaction bed, a fan, and other components. Compared with direct combustion, catalytic combustion has a lower temperature and more complete combustion. The catalytic combustion equipment uses catalysts with noble metals or noble metal oxides (usually platinum, palladium, and other noble metal compounds), which can oxidize organic pollutants in exhaust gases into carbon dioxide and water at relatively low temperatures. It should be noted that the addition of a catalyst cannot change the original chemical equilibrium but only accelerates the chemical reaction speed, and the nature of the catalyst itself remains unchanged before and after the reaction. Noble metal catalysts are added to the incinerator to catalyze the combustion of organic waste gases and produce non-toxic water and carbon dioxide through an oxidation reaction, thereby achieving the effect of waste gas treatment. The catalyst can reduce the ignition temperature required for the thermal combustion reaction and save the operation cost of the waste gas treatment project. Compared with traditional exhaust gas purification technologies, catalytic combustion exhaust gas purification is more thorough. The catalytic combustion technology has no open flame throughout the reaction process and has higher safety. RCO catalytic combustion waste gas treatment equipment has a wide range of applications. It can handle organic waste gases from various industries. The device has a simple structure and high efficiency (up to 95%). In terms of energy conservation and emission reduction, the catalytic combustion technology is more in line with environmental protection requirements due to its advantages such as no secondary pollution. It is an exhaust gas purification device promoted by the current national environmental protection department. Principle of Catalytic Combustion Equipment Reaction Flowchart After the organic waste gas is filtered by the flame arrester, the main inlet valve and the bypass valve are synchronously reversed, and then enter the heat exchanger. The exhaust gas is heat-exchanged by the heat exchanger and heated in the preheater after rising to a certain temperature so that the temperature reaches the catalytic ignition temperature (usually about 250°C). When the exhaust gas reaches the ignition temperature, it enters the catalytic reaction bed. Under the action of the catalyst, the organic exhaust gas oxidizes to produce harmless water and carbon dioxide and emits a certain amount of heat. After the reaction, the high-temperature gas enters the heat exchanger again. After heat transfer, it is discharged into the atmosphere through the induced draft fan at a lower temperature. Equipment Characteristics (1) Platinum and palladium plated on honeycomb ceramics are used as catalysts, with a purification efficiency of 97 – 100%. The equipment has a long service life and can be regenerated. The gas flow is smooth and the resistance is small. (2) Complete safety facilities: fireproof dust collector, pressure relief holes, over-temperature alarms, and other protection facilities. (3) It takes 15 – 30 minutes of full-power preheating. Only the fan power is consumed during operation. When the concentration of exhaust gas is low, automatic intermittent compensation heating is adopted. (4) The waste heat can be returned to the drying channel for drying, reducing the power consumption in the original drying channel and can also be used for heat energy reuse in other aspects of the factory. Activated Carbon Adsorption Desorption + CO Catalytic Combustion Equipment (Working Principle) Activated carbon adsorption and desorption + catalytic combustion equipment first adsorbs and desorbs the exhaust gas to make the exhaust gas concentration appropriate and then burns it in the exhaust gas combustion furnace to reduce the combustion cost. Organic exhaust gas enters the activated carbon adsorption chamber under the action of the induced draft fan. Because activated carbon has many micropores, a large specific surface area, and strong adsorption capacity, the organic exhaust gas is adsorbed in the micropores of the activated carbon, and clean air is discharged at this time. After a period of time, the activated carbon becomes saturated and stops adsorbing. At this time, the organic waste gas is concentrated in the activated carbon adsorption layer. Then we use catalytic combustion technology to desorb and regenerate the saturated activated carbon and put it back into use. The organic waste gas with high concentration, low air volume, and high temperature desorbed by activated carbon filters into a special plate heat exchanger and exchanges energy with the high-temperature gas after the catalytic reaction. At this time, the temperature of the exhaust gas source is increased for the first time, and then the gas with a certain temperature enters the preheater for the second time. In the first stage of the catalytic reaction, the organic waste gas is partially decomposed at a low temperature, and energy is released. The waste gas source is directly heated to increase the temperature to the optimal temperature of the catalytic reaction. Only when the temperature detection system meets the temperature requirement of the catalytic reaction can it enter the catalytic combustion chamber. The organic waste gas is thoroughly decomposed in the reaction process, and a large amount of heat is released at the same time. The purified gas converts heat energy into cold air through a heat exchanger, and the clean gas is exhausted by an induced draft fan. Organic matter maintains spontaneous combustion by using the heat released from oxidation combustion. If the concentration of the desorbed exhaust gas is high enough and CO does not need electric power heating under normal conditions, it can achieve real energy conservation and environmental protection. At the same time, the whole device is safe, reliable, and has no secondary pollution. Equipment Characteristics The equipment has an advanced principle, unique materials, stable performance, simple operation, safety and reliability, energy conservation and labor saving, no secondary pollution, a small occupied area, and light weight. The adsorption bed adopts a drawer structure, which is convenient for filling and replacement. Compared with granular activated carbon, honeycomb activated carbon, a new type of activated carbon adsorption material, has superior dynamic performance and is very suitable for use in high air volume. Noble metal catalysts supported by honeycomb ceramics are used in the catalytic combustion chamber, with low resistance and high activity. When the concentration of organic waste gas is above 2000 ppm, it can maintain spontaneous combustion. Low power consumption. Because of the small resistance of the bed, a low-pressure fan can be used. It not only consumes less power but also has low noise. The power of the exhaust fan is shown in the attached table. When catalytic combustion occurs, it requires electric heating to start. After the start of catalytic combustion, the combustion heat of organic compounds can be sufficient to sustain the reaction.
