vocs organic waste gas treatment methods are now more commonly used: activated carbon + thermal regenerative catalytic combustion method, zeolite rotor + thermal regenerative catalytic combustion method, RTO thermal regenerative combustion method, etc., the specific process of these methods and the characteristics of the advantages of how? Here with the Everest blue editorial to understand.
VOCs organic waste gas treatment activated carbon + regenerative catalytic combustion method process
1. Adsorb and compress the volatile organic waste gases (VOCs) with the activated carbon module first to advance the concentration;
2. The high concentration of waste gas molecules are desorbed and sent to the catalytic oxidation furnace for flameless combustion, decomposed into CO2 and H2O, to achieve the purpose of purification of organic waste gas.
Advantages of activated carbon + thermal regenerative catalytic combustion method
1. the concentration of organic waste gas can be up to 10-15 times, which is more suitable for large air volume and low concentration of organic waste gas treatment;
2. it takes only 15-30 minutes for the equipment to start and warm up to the ignition temperature, with low energy consumption;
3. the honeycomb catalyst impregnated with palladium and platinum, which is the most advanced precious metal, has a large surface area, low resistance and high purification rate;
4. the waste heat of the system can be returned to the baking channel to reduce the power consumption in the original baking channel, and can also be used as a heat source in other areas;
5. The catalyst is generally replaced in five years, and the carrier can be regenerated, so it has a long service life;
6. the outside of the equipment is at room temperature, with high safety and purification efficiency of more than 95%;
7. the use of electric heating to help combustion, simple and convenient;
8. the whole operation process to achieve full automation PLC control, convenient and reliable.
VOCS organic waste gas treatment zeolite rotor + regenerative catalytic combustion method process
1. use zeolite rotor to adsorb and compress volatile organic gases (VOCs) first, and improve the concentration. 2;
2. the high concentration of waste gas molecules after desorption into the catalytic oxidation furnace for flameless combustion, decomposition into CO2 and H2O, to achieve the purpose of organic waste gas purification.
Advantages of zeolite rotor + regenerative catalytic combustion method
1. Zeolite rotor has stronger adsorption capacity for organic waste gas and better filtration effect;
2. the pressure drop generated by zeolite rotor adsorption of VOCs is very low, which can greatly reduce the power energy consumption;
3. the concentration of organic waste gas can be up to 15-20 times, the treatment effect is better;
4. it can desorb organic waste gas with ignition point around 200℃, which has a wider application range than activated carbon;
5. The service life of zeolite rotor is longer;
6. zeolite rotor occupies less space, more flexible system settings;
7. the modular design of the whole system, providing continuity and unmanned operation mode;
8. system automation control, single key start, simple manipulation, and can be equipped with human-computer interface, monitoring important operation data.
vocs organic waste gas treatment RTO regenerative thermal combustion method flow
1. The collected organic waste gas is directly transported to the heat storage room through the pipeline by the fan, and is heated by burning natural gas;
2. Organic waste gas is oxidised and decomposed into CO2 and H2O when it is heated to above 760℃ to achieve purification.
Advantages of RTO regenerative combustion method
1. RTO system is suitable for small air volume, medium and high concentration of organic waste gas treatment;
2. It can treat organic waste gas with large elasticity and changing concentration;
3. the sensitivity to dust is low, can effectively improve the purification efficiency, purification rate of about 99%;
4. RTO thermal efficiency of about 95%, and the system maintenance work is less, the operation of higher safety and reliability;
5. the heat storage body can be replaced or cleaned, comprehensive removal of organic sediments, and the device pressure loss is small;
6. two-chamber RTO device VOCs removal rate of 95% to 98%, three-chamber RTO device VOCs removal rate can reach more than 98%.
