Manufacturer provides catalytic combustion specifications for Xiamen catalytic combustion

Description :

　　1) Low ignition temperature, fast reaction rate, and energy saving. During catalytic combustion, the catalyst plays a role in reducing the activation energy of VOCs molecules reacting with oxygen molecules and changing the reaction pathway.

　　2) High processing efficiency, low emissions of secondary pollutants and greenhouse gases. The purification rate of VOCs exhaust gas treated by catalytic combustion is usually over 95%, and the final products are mainly CO2 and H2O. Due to the low temperature of catalytic combustion, the generation of NOx is greatly reduced. The CO2 emissions from auxiliary fuel consumption account for a large proportion of the total CO2 emissions, and the reduction in auxiliary energy consumption clearly reduces greenhouse gas CO2 emissions.

　　3) Widely applicable, catalytic combustion can treat almost all hydrocarbon organic waste gases and odorous gases, and is suitable for treating a wide range of VOCs concentrations. It is economically reasonable to use catalytic combustion method to treat VOCs waste gas with low concentration, high flow rate, multiple components and no recycling value.

　　RCO type exhaust gas treatment catalytic combustion equipment, principle of thermal storage combustion technology: When the ambient temperature air is switched into the thermal storage chamber 1 by the reversing valve, it is heated when passing through the thermal storage chamber (ceramic balls or honeycomb bodies, etc.), and the ambient temperature air is heated to near the furnace temperature in a very short time (generally 50-100 ℃ lower than the furnace temperature). After the high-temperature hot air enters the furnace, it draws the gas in the surrounding furnace to form a lean and oxygen deficient high-temperature airflow with an oxygen content much lower than 21%. At the same time, fuel (fuel or gas) is injected into the vicinity of the lean and high-temperature air, so that the fuel burns in a lean oxygen (2-20%) state; At the same time, the flue gas after combustion in the furnace is discharged into the atmosphere through another heat storage chamber. The high-temperature flue gas in the furnace transfers sensible heat to the heat storage body when passing through it, and then the low-temperature flue gas at 150-200 ℃ is discharged through a reversing valve.

　　Catalytic combustion is a purification method that uses catalysts to oxidize and decompose combustible substances in exhaust gas at lower temperatures. So, catalytic combustion is also known as catalytic chemical conversion. Due to the acceleration of the oxidation decomposition process by the catalyst, most hydrocarbons can be completely oxidized by the catalyst at temperatures of 300-450 ℃.

　　Compared with the thermal combustion method, catalytic combustion requires less auxiliary fuel, consumes less energy, and has smaller equipment and facilities. However, the promotion and application of this method in industrial production processes have been affected by issues such as catalyst poisoning, replacement of catalytic beds, and high cleaning costs.
