Catalytic combustion equipment

1、Process Description

Dry pre-treatment+photocatalysis+adsorption desorption catalytic combustion method

The working process of this device can be divided into two stages, namely the activated carbon adsorption stage and the activated carbon desorption regeneration stage. The working principles of these two stages are as follows:

① Activated carbon adsorption process:

The exhaust gas is collected by the gas collection hood, and after pre-treatment, it enters the activated carbon adsorption device. When the organic exhaust gas passes through the activated carbon layer, the organic components in the exhaust gas are attracted to the surface of the activated carbon and concentrated to maintain it. The organic components are separated from other components, and other components of gas (clean gas) are discharged by the fan.

② Activated carbon desorption process:

After using activated carbon for a period of time and adsorbing a certain amount of solvent, its adsorption capacity will decrease or lose. At this time, the activated carbon needs to be desorbed and regenerated. After regeneration, the activated carbon can resume its adsorption function and continue to be used. During regeneration, start the power supply of the catalytic combustion device preheating chamber, preheat the air, and send the preheated gas into the adsorption box. After the activated carbon is heated in the box, the solvent adsorbed by the activated carbon evaporates, and the solvent is sent to the catalytic combustion chamber for combustion through a fan, decomposing to generate inorganic substances such as CO2 and H2O. Part of the hot air returns to the activated carbon adsorption box to continue heating the activated carbon, while the other part is discharged, The activated carbon can be regenerated by circulating the hot air internally multiple times.
