Abstract

The invention provides a flue gas denitrification agent and a preparation method thereof, which comprises the following raw materials according to weight percentage: 5-10% of urea, 5-10% of ganoderma acid, 1-3% of carboxymethyl cellulose sodium, pyrolusite Powder 20-40%, the balance is water. Preparation method: Weigh urea, ganoderma acid, sodium carboxymethylcellulose, pyrolusite powder and water according to the ratio, and then mix and stir until viscous material is formed. The denitrification agent has high desulfurization and denitrification efficiency and long operation time.

Description

technical field [0001] The invention belongs to the technical field of flue gas treatment, and in particular relates to a flue gas denitration agent and a preparation method thereof. Background technique [0002] my country uses coal as the main energy source, and its coal consumption ranks first in the world, while coal consumption for power generation accounts for more than 50% of the total coal consumption. Coal-fired power generation emits SO 2 , NO x and elemental mercury and other pollutants, causing problems such as acid rain, smog, the hole in the ozone layer, and heavy metal pollution. At present, the existing pollutant removal equipment in thermal power plants basically meets the emission standards, but the "Coal Power Energy Conservation and Emission Reduction Upgrading and Transformation Action Plan (2014-2020)" puts forward higher requirements for "ultra-clean" emissions, so the use of existing The coordinated removal of multiple pollutants by flue gas treatm...
