A kind of energy-efficient catalytic combustion device
Technical field
The present invention relates to a kind of energy-efficient catalytic combustion device.
Background technology
The enterprises such as coating, papermaking, plastics, oil refining and chemical industry are produced in production or storage and transport process containing various organic exhaust gas,
The various waste gas treatment equipments such as corresponding processing catalysis burning, spray cleaning, plasma, UV photodissociation.The organic exhaust gas volatilized
In also contain various poisonous and harmful substances, such as volatile phenol, NH3, benzene homologues, sulfide and organic amine, severe contamination environment,
Site operation personnel's physical and mental health is caused harm simultaneously.Combustion is generally used for the waste gas of this organic substance containing higher concentration
Burning method, current processing method has flame combustion, catalysis burning, heat-accumulation combustion or heat-storage catalytic burning.But it is non-in the waste gas that volatilizees
Methane total hydrocarbon concentration is generally in 1000~6000mg/Nm3, for flame combustion, and the organic matter content in waste gas is not enough in itself
To burn, it is necessary to which additionally EGT lifting could be arrived reaction temperature by addition auxiliary fuel, the innoxious process of waste gas is completed.Heat
The temperature of power burning is general at 540~820 DEG C.In order to reduce reaction temperature, the concept of catalysis burning is introduced, in catalyst
In the presence of, temperature needed for organic exhaust gas innocent treatment procedure only has 250~400 DEG C, and this is also that catalytic combustion process can
The main cause being widely used.Heat-storage catalytic burning is exactly the combined process of heat-accumulation combustion and catalysis burning.
