In the process of chemical reactions, a technique known as catalytic combustion is employed, which utilizes a catalyst to lower the combustion temperature and expedite the complete oxidation of toxic and harmful gases. The catalyst's carrier is constructed from porous materials, providing a large specific surface area and appropriate pore size. When organic gases, heated to between 300 and 450℃, pass through the catalytic layer, oxygen and these gases are adsorbed onto the catalyst's porous surface. This increases the likelihood of contact and collisions between oxygen and organic gases, bolstering their reactivity. This intense interaction results in the organic gases vigorously combining with oxygen to produce carbon dioxide and water, generating heat in the process. Consequently, these gases are transformed into non-toxic and harmless substances.
The catalytic combustion device is primarily composed of several components:
Heat Exchanger: Used to preheat unclean gases and increase reaction efficiency.
Combustion Chamber: The gases reach the required reaction temperature here for oxidation reactions to take place.
Catalytic Reactor: The catalyst facilitates the reaction between organic gases and oxygen in this component.
Heat Recovery System: Recovers the heat generated during the reaction to preheat the gases entering the system.
Emission Stack: Releases the purified flue gas into the atmosphere.
Its purification process is as follows: before entering the combustion chamber, the unclean gases are preheated by the heat exchanger. They then enter the combustion chamber, where they reach the required reaction temperature. The oxidation reaction then takes place within the catalytic reactor. Once purified, the flue gas releases some of its heat through the heat exchanger before being released into the atmosphere via the stack.
Through this system, catalytic combustion can effectively reduce harmful substances in industrial exhaust gases, meeting environmental protection requirements.
