Classification of VOCs exhaust gas burners Xiamen catalytic combustion

Description :

　　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.

　　Characteristics of acid mist purification tower:

　　The fiberglass acid mist purification tower uses fillers to purify exhaust gas, which is suitable for the treatment of continuous and intermittent emissions of exhaust gas; The process is simple, and the management, operation, and maintenance are quite convenient and concise, without causing any impact on the production of the workshop; Widely applicable and capable of purifying multiple types of pollutants simultaneously; Low pressure drop, high operational flexibility, and excellent defogging performance; The tower body can be made of materials such as FRP/PP/PVC according to the actual situation; The packing adopts efficient and low resistance Ball rings, which can thoroughly remove odors and harmful substances from the gas.

　　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.
