There are various treatment methods for organic waste gas from foundries, one of which is activated carbon adsorption desorption combined with catalytic combustion. The specific processing steps are as follows: activated carbon adsorption and desorption: Organic waste gas is adsorbed onto the surface of activated carbon through an activated carbon adsorption tower. When activated carbon adsorption is saturated, organic matter can be desorbed by heating or reducing pressure, allowing activated carbon to be reused. Catalytic combustion: Organic waste gas is added to a catalyst through a catalytic combustion device at high temperatures, causing the organic matter to undergo oxidation reactions and convert into harmless carbon dioxide and water.

The adsorption catalytic combustion method for organic waste gas from casting production has the following advantages: good treatment effect: this method can effectively remove harmful substances in organic waste gas, and the treatment effect is good and stable. Low energy consumption: The combination of activated carbon adsorption and desorption and catalytic combustion does not require a large amount of energy consumption. Simple equipment: The equipment required for this method is relatively simple, easy to install and operate, and has a lower cost. Reusable: The organic matter analysis after activated carbon adsorption can be desorbed simultaneously through different heating or pressure reducing methods, making the activated carbon reusable for students.

Environmental protection: The waste gas emissions after treatment by this method are small, and the impact on the environment is relatively small, which meets environmental protection requirements. However, some factors need to be considered, such as the selection of catalysts, control of treatment temperature, and maintenance of treatment equipment. In the specific implementation process, adjustments and optimizations need to be made according to the actual situation. In short, the combination of activated carbon adsorption and catalytic combustion can effectively treat the organic waste gas generated by casting.
