Description

technical field [0001] The invention belongs to the field of boiler tail flue gas purification and treatment, and more specifically relates to a biomass adsorption material purification treatment flue gas system. Background technique [0002] With the continuous expansion of domestic industrial scale, the emission of air pollutants has increased rapidly, and the SO emitted into the atmosphere 2 , NO x , heavy metals, etc. will cause serious damage to the natural environment and human health, and the emitted CO 2 It is a greenhouse gas that causes global warming and environmental degradation. Therefore, it is imminent to deal with the tail flue gas emissions from industrial combustion represented by power plant boilers. my country attaches great importance to the environmental problems caused by flue gas emissions, and has been increasing research on flue gas emissions, especially denitrification and desulfurization, but there are still certain limitations in these fields....
