Brief Introduction of Catalytic Combustion Device for Adsorption and Desorptionof Activated Carbon
Activated carbon adsorption& desorption and catalytic combustion is a new generation of VOCs treatment equipment independently developed by our company. It is a method that organically combines adsorption concentration unit and thermal oxidation unit. It is mainly suitable for low concentration organic gases, and it is not suitable to treat organic waste gases by direct combustion or catalytic combustion method and adsorption recovery method. Especially in the case of large air volume treatment, it can be obtained. Satisfactory economic and social effects. After adsorption, purification and desorption, it is converted into organic waste gas with low air volume and high concentration, which is treated by thermal oxidation, and the heat released from combustion of organic matter is effectively utilized.
Organic waste gas is first filtered by dry filter, and the particulate pollutants in the waste gas are intercepted and removed. Then, the organic solvent is adsorbed on the surface of activated carbon by using honeycomb activated carbon with large specific surface area. The treated clean gas is discharged at high altitude through fans and chimneys.
Activated carbon saturates after a period of adsorption operation, starting the desorption-catalytic combustion process of the system, desorbing the organic solvents previously adsorbed on the surface of activated carbon by hot air flow, and transforming them into harmless substances such as CO2 and water vapor through catalytic combustion reaction, and releasing heat. The heat generated by the reaction is reused to the desorption additional hot air flow through the heat exchange part. When the desorption reaches a certain degree, the exothermic heat is balanced with the additional heat, and the desorption regeneration process can be completed without any additional heat
1. Adsorption and purification efficiency is high, treatment effect is stable, to ensure that the emission of waste gas meets the standard.
2. It has the function of manual and automatic desorption. The noble metal catalyst is selected to convert organic matter through catalytic combustion reaction. The catalytic efficiency is high and the performance is stable
3. Adopting PLC control, matching operable touch screen, easy to use and operate, simple maintenance and management.
4. It has multiple safety measures. The main reactor is equipped with explosion relief devices, multi-point temperature detection, fault alarm and emergency disposal capabilities.
Activated carbon adsorption+desorption-catalytic combustion treatment unit adopts the combined process of adsorption+desorption to treat high-volume, medium and low-concentration organic waste gases. The organic solvents that can be treated include benzene, ketone, lipid, alcohol, aldehyde, ether, alkane and their mixtures. It can be widely used in automobile, shipbuilding, motorcycle, bicycle, household appliances, spray paint of container factories and organic waste gas purification of painting workshop. It can also be used with assembly line equipment such as shoe glue, tin printing, chemical plastics, printing ink, cable and enamelled wire.
