▎ 摘  要

NOVELTY - An agent comprises 40-70 pts. wt. urea, 15-30 pts. wt. activated carbon, 2-5 pts. wt. vanadium pentoxide, 10-15 pts. wt. graphene, 3-8 pts. wt. potassium chlorate, 6-15 pts. wt. potassium ferrioxalate, 1-5 pts. wt. tannin extract, 1-3 pts. wt. neodymium nitrate, 2-3 pts. wt. lanthanum nitrate, 20-30 pts. wt. bentonite, 10-20 pts. wt. quicklime and 5-15 pts. wt. talc. USE - Agent is used for wet-denitrifying industrial furnace flue gas (claimed). ADVANTAGE - The agent has high denitrification efficiency, and reduces the content of nitrogen oxide in flue gas. The denitrified flue gas reaches the national emission standards. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of the agent, which involves mixing the raw materials, milling, and sieving. The grain size of sieved particles is 200-300 mu m; and (2) application of the agent in industrial furnace flue gas wet-denitrification process, which involves dissolving the denitrification agent in demineralized water, atomizing the mixed solution, and then passing into the flue gas.
