Catalytic oxidation system (CO)
Catalytic oxidation is a typical gas-solid catalytic reaction, which is in essence the deep oxidation of reactive oxygen species.In the process of catalytic oxidation, the role of the catalyst is to reduce the activation energy, and at the same time, the catalyst surface has adsorption, so that the reactant molecules are enriched on the surface, which improves the reaction rate and speeds up the reaction.With the help of catalyst, the organic waste gas can be oxidized without flame and decomposed into CO2 and H2O at a lower ignition temperature.Its reaction process is: in the exhaust gas in the process of catalytic oxidation, flue gas pipelines by the fan into the heat exchanger, heat the gas to the light-off temperature catalytic oxidation need, to make it through the catalyst bed layer oxidation, due to the presence of catalysts, catalytic oxidation of the light-off temperature of about 250 ~ 300 ℃, much lower than direct oxidation of oxidation temperature of 650 ~ 800 ℃, so than direct oxidation method for low energy consumption.
The mechanism of catalysis is a complicated problem.In a chemical reaction process, the addition of catalyst cannot change the original chemical equilibrium, but only change the rate of chemical reaction, and the nature of catalyst itself does not change before and after the reaction.So how does the catalyst speed up the reaction?Since the catalyst does not change before and after the reaction, the catalyst does not participate in the reaction after all. In fact, the catalyst itself participates in the reaction, and it is because of its participation that the reaction changes the original way, reduces the activation energy of the reaction, and thus accelerates the reaction speed.For example, reaction A+B→C is formed by intermediate active binding (AB).
Namely: A + B - {B} - C
The reaction is slow.When catalyst K is added, the reaction is carried out in an easy way:
A + B + 2 K - > {AK} + {BK} - > {CK} - > C + 2 K + K
The transition from {AB} to C is no longer needed, speeding up the reaction, while the catalyst does not change its properties.
Characteristics of catalytic oxidation system:
1, high treatment efficiency, no secondary pollution, purification efficiency can reach more than 98%, ensure that the exhaust meets the environmental emission standards;
2. Wide application range, suitable for volatile organic compounds (VOC) with complex components, large air volume, medium and low concentration, and odorous gases;
3. Low oxidation temperature, low operating cost, reasonable utilization and recovery of waste heat, energy saving and significant economic benefits;
4. Flame free oxidation, multiple safety facilities, reliable operation and high production safety performance;
5. Compact equipment layout, small floor area, saving land and installation costs.
