This invention relates to the field of air pollution control technology, specifically to a method for purifying exhaust gas from air pollution denitrification and desulfurization, including: cyclone spray desulfurization (using nano-scale composite absorbent slurry to efficiently absorb SO2 and remove particulate matter in a cyclone reactor), and two-stage catalytic denitrification (using nano-catalysts in a low-temperature zone to promote NO removal). x The process involves reduction, enhanced reaction in a high-temperature zone using a novel honeycomb ceramic carrier to support a vanadium-tungsten-titanium-based catalyst, deep synergistic purification (further removal of residual pollutants and aerosols through electrostatic dust removal coupled with oxidation adsorption), and an intelligent control system (real-time optimization of absorbent ratio, catalyst temperature, and flow rate parameters). This method addresses the problems of catalyst poisoning, high energy consumption, and insufficient treatment efficiency in traditional processes by modifying the absorbent with nanomaterials, employing temperature gradient catalytic reactions, and utilizing a multi-pollutant synergistic removal mechanism. The system achieves a desulfurization efficiency ≥98%, a denitrification efficiency ≥97%, and particulate matter emissions ≤10 mg / m³. 3 SO2 ≤ 35 mg / m³ 3 NO x ≤50mg / m 3 It meets ultra-low emission standards.
