Collaborative treatment process for solid waste pyrolysis flue gas

The invention discloses a collaborative treatment process for solid waste pyrolysis flue gas, which relates to the technical field of waste gas treatment, and aims to solve the problem that the existing desulfurization, denitrification and dust removal process cannot meet the stable emission requirement. The technical scheme is characterized by comprising the following steps of S1, incineration: incinerating organic impurities in flue gas, S2, high-temperature section reduction: reducing NOx in the flue gas, S3, flue gas cooling: cooling the flue gas to form low-temperature flue gas, S4, desulfurization adsorption: carrying out reaction on the absorbent and SOx in the flue gas to desulfurize, S5, conducting efficient dust removal and flue gas dust removal, S6, conducting efficient denitration, specifically, inputting the flue gas into an efficient denitration device, and removing NOx pollution in the flue gas under a catalytic reaction, and S7, tail gas washing: washing and spraying the flue gas to obtain cle
