System structure
The RCO catalytic decomposition device consists of a pretreatment device, a preheating device, a catalytic combustion device, and an explosion-proof device.
① Exhaust gas pretreatment: In order to avoid catalyst bed blockage and catalyst poisoning, the exhaust gas must be pretreated before entering the bed to remove dust, droplets and catalyst poisons in the exhaust gas.
② Preheating device: Preheating device includes exhaust gas preheating device and catalyst burner preheating device. Because the catalyst has a catalytic activity temperature, it is called the catalyst light-off temperature for catalytic combustion. The temperature of the exhaust gas and the bed must reach the light-off temperature for catalytic combustion. Therefore, a preheating device must be provided. However, in the case where the temperature of the exhaust gas itself is relatively high, such as enameled wire, insulation material, baking paint and other dry exhaust gas, the temperature can reach 300 ° C or more, it is not necessary to set a preheating device.
③ Catalytic combustion device: Generally, a fixed-bed catalytic reactor is used. The design of the reactor is carried out according to specifications, which should be easy to operate, easy to maintain, and convenient for loading and unloading catalyst.
④ Explosion-proof device: Explosion-proof for diaphragm pressure relief, installed on the top of the host. When an accident occurs during the operation of the equipment, the pressure can be cracked in time to prevent the accident.
