Cooperative treatment system for solid waste pyrolysis flue gas

The invention discloses a cooperative treatment system 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 key point of the technical scheme is that the cooperative treatment system comprises an incinerator, a high-temperature section treatment system, a low-temperature denitrification system and a tail end washing system which are communicated through a flue; the high-temperature treatment system comprises a high-temperature section reducing agent spraying device, a quenching device, an adsorbent feeding device and an efficient dust removal device; the low-temperature denitration system comprises an efficient denitration device, and a plurality of catalyst layers are mounted in the efficient denitration device; the tail end washing system comprises a high-efficiency desulfurization device consisting of a plurali
