Description

technical field

[0001] The invention relates to the field of desulfurization equipment, in particular to a system and method for cooling flue gas of an activated carbon or activated coke dry method desulfurization adsorption tower. Background technique

[0002] Activated coke or activated carbon flue gas desulfurization technology belongs to the dry recovery desulfurization process, relying on the adsorption and analysis of sulfur dioxide by activated coke or activated carbon to complete the flue gas desulfurization cycle. Due to the spectral adsorption of activated coke or activated carbon, this technology can remove many harmful substances at the same time. In the desulfurization process, basically no water is consumed, no waste water and waste residue are generated, and it has excellent environmental protection performance. The desulfurization product is high-concentration sulfur dioxide gas, which can produce sulfuric acid, sulfur, liquid sulfur dioxide, fertilizer and ...
