The catalytic combustion device adopts low-temperature oxidation technology, that is, under the action of a precious metal catalyst, the organic gas is heated to a decomposition temperature to rapidly oxidize the gas to H2O and CO2, thereby achieving the purpose of treatment. Catalytic combustion is a type of flameless combustion, which is ideal for use in high-concentration, low-air volume exhaust environments.
The organic waste gas enters the heat exchanger after passing through the filter and flame arrester, and the waste gas is heated to the catalytic reaction temperature (250-300 ° C) through the heat exchanger, and then enters the combustion chamber. When the reaction bed is catalyzed by the combustion chamber, hydrocarbon molecules and oxygen molecules in the mixed gas are respectively adsorbed on the surface of the catalyst and activated. As the surface adsorption reduces the activation energy of the reaction, the hydrocarbons and oxygen molecules are rapidly oxidized at a lower temperature to produce CO2, H2O, and emit a certain amount of heat.
The key to catalytic combustion is to choose the right catalyst. On the one hand, low-temperature activity is required in order to start the reaction at the lowest possible temperature. The combustion reaction is an exothermic reaction. A large amount of heat is released to make the surface of the catalyst reach a high temperature of 500-1000 ° C, and the catalyst is liable to reduce its activity due to melting, so the catalyst is required to be resistant to high temperatures.
Mainly used in: purification of organic waste gas in paint, rubber, plastic, resin, leather, insulation materials, printing, food and foundry industries, such as organic mixed gases such as aromatics, aldehydes, esters, alkanes.
The exhaust gas components must not contain the following substances, otherwise it will cause catalyst poisoning, affect the reaction effect and reduce the service life.
