Regenerative Catalytic Oxidition is an organic waste gas treatment equipment that combines low-temperature catalytic oxidation with heat storage technology. It is an environmental protection equipment used to treat medium and high concentration organic waste gas purification. RCO regenerative catalytic combustion equipment is developed on the basis of RTO regenerative incineration equipment. A layer of catalyst is arranged on the thermal storage ceramic layer of the thermal storage equipment, so that the incoming waste gas is catalytically burned at 200℃-400℃ and decomposed into carbon dioxide and water, thereby achieving the purpose of purifying the waste gas.
Regenerative Catalytic Oxidition is an organic waste gas treatment equipment that combines low-temperature catalytic oxidation with heat storage technology. It is an environmental protection equipment used to treat medium and high concentration (1000mg/m³-8000mg/m³) organic waste gas. RCO regenerative catalytic combustion equipment is developed on the basis of RTO regenerative incineration equipment. A layer of catalyst is arranged on the thermal storage ceramic layer of the thermal storage equipment, so that the incoming waste gas is catalytically burned at 200℃-400℃ and decomposed into carbon dioxide and water, thereby achieving the purpose of purifying the waste gas.
The exhaust gas is first preheated by the ceramic material filling layer (bottom layer) to store heat and exchange heat. Its temperature almost reaches the temperature set by the catalyst layer (middle layer) for catalytic oxidation. At this time, some pollutants are oxidized and decomposed.
The exhaust gas continues to heat up through the heating zone (electric heating or natural gas heating can be used) and maintains the set temperature; it then enters the catalyst layer to complete the catalytic oxidation reaction, that is, the reaction generates CO2 and H2O, and releases a large amount of heat to achieve the expected treatment effect.
The gas after catalytic oxidation enters other ceramic material filling layers, recovers heat energy and is discharged into the atmosphere through a rotary valve. The exhaust temperature after purification is only slightly higher than the temperature before the exhaust gas treatment. The system operates continuously and automatically switches. Through the rotary valve, all ceramic filling layers complete the heating, cooling, and purification cycle steps, and heat is recovered.

Pretreatment device
In order to avoid clogging of the catalyst bed and catalyst poisoning, the exhaust gas must be pretreated before entering the bed to remove dust, droplets and substances toxic to the catalyst in the exhaust gas.
Preheating device
The preheating device includes an exhaust gas preheating device and a catalyst burner preheating device. Because the catalyst has a catalytic activity temperature, which is called the catalyst ignition temperature for catalytic combustion, the temperature of the exhaust gas and the bed must reach the ignition temperature before catalytic combustion can be carried out. Therefore, a preheating device must be set. However, for occasions where the exhaust gas itself has a high temperature, such as enameled wire, insulating materials, baking paint and other drying exhaust, the temperature can reach more than 300°C, so there is no need to set a preheating device.
Catalytic combustion device
A fixed bed catalytic reactor is generally used. The design of the reactor is carried out according to the specifications, and it should be easy to operate, easy to maintain, and easy to load and unload the catalyst.
Explosion-proof device
It is a diaphragm pressure relief explosion-proof device installed on the top of the main engine. When an accident occurs during equipment operation, the pressure relief valve can be released in time to prevent the accident.
