Problems solved by technology
[0003] Since flue gas denitrification technology started relatively late in my country, the technologies used in domestic flue gas denitrification projects are also imported from developed countries and regions such as Europe, the United States, and Japan. Currently, the main applied denitrification processes are divided into two categories Part of it, namely the selective catalytic reduction method (SCR method) and the selective non-catalytic reduction method (SNCR method). The treatment cost is high; while the SNCR method has less investment and lower subsequent operation treatment costs, but the denitrification efficiency can only reach <60%, which cannot meet the increasingly stringent national emission requirements for nitrate in flue gas

The invention discloses a flue gas denitrification purification device which comprises a cabin communicated with the right end of a boiler flue gas pipeline, wherein a purified flue gas outlet is formed in the right side of the cabin; the upper end on the left part of an inner cavity of the cabin is connected with multiple oxidizing agent spraying devices; the oxidizing agent spraying devices are connected with an oxidizing agent storage bin filled with an oxidizing agent solution; the lower end on the right part of the inner cavity of the cabin is connected with a connecting plate; a part between the upper end of the connecting plate and the top of the inner cavity of the cabin is connected with a pipeline; the right side of the connecting plate in the cabin is filled with a urea solution; the other end of the pipeline stretches into the urea solution. The flue gas denitrification purification device is high in denitrification efficiency, and low in investment and operating cost; a process is simple.
Description
technical field [0001] The invention relates to a flue gas purification device, in particular to a flue gas denitrification purification device. Background technique [0002] In recent years, the problem of air pollution has become more and more serious. As a large developing country, my country will still face the serious situation of increasing air pollution for a long time to come. With the continuous increase of energy demand, the pollution problem caused by flue gas emission has become increasingly prominent, and the problem of atmospheric environmental pollution control has attracted extensive attention from all over the world. It is fundamental to develop high-efficiency, energy-saving, and cost-effective flue gas purification equipment and technologies. Solve the different demands of development and environmental protection, current and long-term. [0003] Since the flue gas denitrification technology started relatively late in my country, the flue gas denitrificati...
