Principle of RCO thermal storage catalytic combustion device
In the industrial production process, the emitted organic exhaust gas enters the rotary valve of the equipment through the induced draft fan, and the inlet gas and outlet gas are completely separated through the rotary valve. The gas is first preheated through the ceramic material filling layer (bottom layer) and undergoes heat storage and exchange. Its temperature almost reaches the temperature set for catalytic oxidation in the catalytic layer (middle layer), at which some pollutants oxidize and decompose; The exhaust gas continues to heat up through the heating zone (upper layer, electric heating or natural gas heating can be used) and remains at the set temperature; It then enters the catalytic layer to complete the catalytic oxidation reaction, which generates CO2 and H2O and releases a large amount of heat to achieve the expected treatment effect. After catalytic oxidation, the gas enters other ceramic filling layers, recovers heat energy, and is discharged into the atmosphere through a rotary valve. The purified exhaust temperature is only slightly higher than the temperature before exhaust gas treatment. The system operates continuously and automatically switches. Through the operation of the rotary valve, all ceramic filling layers complete the cycle steps of heating, cooling, and purification, and heat is recovered. The RCO thermal storage catalytic combustion device uses rotary valves to replace numerous valves and complex hydraulic equipment in traditional equipment. The organic matter removal rate can reach over 99%, and the heat recovery rate can reach 95-97%.
Scope of application of RCO thermal storage catalytic combustion device
RCO thermal storage catalytic combustion equipment can be directly applied to the purification of organic waste gases with medium to high concentrations (1000mg/m3 to 80000 mg/m3); RCO thermal storage catalytic combustion equipment can also be applied to activated carbon adsorption concentration catalytic combustion systems, replacing catalytic combustion and heater components. The RCO thermal storage catalytic combustion equipment treatment technology is particularly suitable for situations with high heat recovery requirements, as well as for situations on the same production line where the composition of exhaust gas often changes or the concentration of exhaust gas fluctuates greatly due to different products. The application industries include painting production lines in factories such as automobiles, shipbuilding, motorcycles, bicycles, household appliances, and containers. The waste gas treatment of production lines such as petroleum, chemical, rubber, paint, coatings, shoe adhesives, plastic products, printing iron cans, printing inks, cables, and enameled lines is particularly suitable for enterprises or drying line waste gas treatment that require heat energy recovery. Energy recovery can be used for drying lines to achieve energy conservation. The types of organic substances that can be processed include benzene, ketones, esters, phenols, aldehydes, alcohols, ethers, and hydrocarbons, among others.
Characteristics of RCO thermal storage catalytic combustion equipment
