High-efficiency dry-method polymer denitration agent as well as preparation method and application thereof

The invention discloses a high-efficiency dry-method polymer denitration agent and a preparation method and application thereof, and particularly relates to the technical field of denitration agent preparation.The denitration agent takes sodium dodecyl benzene sulfonate, lauryl sodium sulfate and alcohol organic matter as polymer additives, takes amino organic matter as a reducing agent and takes an iron-based molecular sieve as a catalyst; a sodium-containing alkaline compound is used as an activating agent, and deionized water is used as a solvent; the mass ratio of the alcohol organic matter to the sodium dodecyl benzene sulfonate to the lauryl sodium sulfate is 1: (0.8-1.5): (0.9-2); the mass ratio of the amino organic matter to the polymer additive to the sodium-containing alkaline compound is 1: (0.1-0.4): (0.01-0.1); the ratio of SiO2 to Al2O3 in the molecular sieve is 15-30, and the mass loading amount of Fe in the iron-based molecular sieve is 0.01-2.0%. The device is specially designed for industria
