VOCs waste gas treatment and maintenance for catalytic combustion in Xiamen

Description :

　　1) Low ignition temperature, fast reaction rate, and energy saving. During catalytic combustion, the catalyst plays a role in reducing the activation energy of VOCs molecules reacting with oxygen molecules and changing the reaction pathway.

　　2) High processing efficiency, low emissions of secondary pollutants and greenhouse gases. The purification rate of VOCs exhaust gas treated by catalytic combustion is usually over 95%, and the final products are mainly CO2 and H2O. Due to the low temperature of catalytic combustion, the generation of NOx is greatly reduced. The CO2 emissions from auxiliary fuel consumption account for a large proportion of the total CO2 emissions, and the reduction in auxiliary energy consumption clearly reduces greenhouse gas CO2 emissions.

　　3) Widely applicable, catalytic combustion can treat almost all hydrocarbon organic waste gases and odorous gases, and is suitable for treating a wide range of VOCs concentrations. It is economically reasonable to use catalytic combustion method to treat VOCs waste gas with low concentration, high flow rate, multiple components and no recycling value.

　　The common method of generating plasma is gas discharge, which refers to the ionization of an electron from a gas atom or molecule through a certain mechanism, forming a gas medium called ionized gas. If ionized gas is generated by an external electric field and forms a conduction current, this phenomenon is called gas discharge. According to the mechanism of discharge, the pressure source properties of the gas, and the geometric shape of the electrode, gas discharge plasma can be mainly divided into the following forms: ① glow discharge; ③ Dielectric barrier discharge; ④ Radio frequency discharge; ⑤ Microwave discharge. Regardless of the form of plasma generated, high-voltage discharge is required. Easy to ignite and pose a danger. Due to the treatment of gaseous pollutants, it is generally required to be carried out at atmospheric pressure.

　　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.
