Abstract

The invention relates to the technical field of coal-fired flue gas treatment, particularly to a coal-fired flue gas treatment composition, a coal-fired flue gas treatment method, a coal-fired flue gas treatment apparatus, and applications of the composition, the method and the apparatus. The coal-fired flue gas treatment composition comprises a dicarbonic acid solution, a nitrogen copper solution and a sodium chloride solution, wherein the dicarbonic acid solution comprises sodium bicarbonate, sodium carbonate and a solvent, the nitrogen copper solution comprises a mother liquor and a seed liquid, the mother liquor is prepared from heat treated copper and a urea solution, and the seed liquid is a urea solution. According to the present invention, the coal-fired flue gas is treated by using the nitrogen copper solution as the catalyst to convert the traditional oxygen-consuming flue gas treatment mode into the oxygen release mode, such that the oxygen content in the flue gas is substantially recovered to the level of the air so as to achieve the harmless treatment of the flue gas; and with the coal-fired flue gas treatment composition, the NOx content in the coal-fired flue gas can be reduced to within 10 mg / m<3> so as to improve the degradation level of nitrogen oxides to a completely-new level.

Description

technical field [0001] The invention relates to the technical field of coal-fired flue gas treatment, in particular to a coal-fired flue gas treatment composition, treatment method, device and application. Background technique [0002] The information disclosed in the Background of the Invention is only intended to increase the understanding of the general background of the invention, and is not necessarily to be taken as an acknowledgment or any form of suggestion that the information constitutes the prior art that is already known to those skilled in the art. [0003] my country's energy is dominated by coal. At present, power generation and heating enterprises will start from SO 2 The total amount of emissions and the concentration of emissions will be technologically improved, and efforts will be made to increase desulfurization. At the same time, with the expansion of the collection scope of sewage charges (from the original "two control areas" to the whole country) an...
