Embodiment 1
[0033] A flue gas denitrification agent, the denitrification agent comprises the following components:
[0034]
[0035] The above-mentioned parts are all parts by weight.
Embodiment 2
[0037] A flue gas denitrification agent, the denitrification agent comprises the following components:
[0038]
[0039]
[0040] The above-mentioned parts are all parts by weight.
Embodiment 3
[0042] A flue gas denitrification agent, the denitrification agent comprises the following components:
[0043]
[0044] The above-mentioned parts are all parts by weight.
[0045] Specifically, the main component of rhodochrosite powder is manganese carbonate, and it also contains some metal substances, such as Fe, Ca, Zn and Mg, etc., which can play a role in decomposition in the denitrification reaction, and can further improve the denitrification effect and efficiency.
[0046] In addition, the main component of soda ash is Na 2 CO 3 , which can interact with NO in water 2 The reaction forms NaNO 3 and CO 2 , reacts with NO in water to form NaNO 2 and CO 2 , to remove nitrogen oxides (NO X ) role.
[0047] In addition, a small amount of Al can be added to the denitrification agent 2 o 3 , BaO, SiO 2 and other metal oxides play a role in decomposition.
[0048] The denitrification partial reaction formula is:
[0049] CO(NH 2 ) 2 +2NO=2H 2 +CO 2 +2H 2 ...

Abstract
The invention relates to a flue gas denitration agent and production and application methods thereof. The denitration agent is prepared from the following components in parts by weight: 2 to 12 partsof activated carbon, 1 to 9 parts of potassium permanganate, 15 to 25 parts of rhodochrosite, 2 to 12 parts of magnesium oxide, 0.2 to 3.8 parts of silicon oxide, 24.5 to 34.5 parts of urea and 24.5 to 34.5 parts of sodium carbonate. The denitration agent provided by the invention contains the activated carbon and the adsorption effect of the denitration agent can be increased; the added urea canreact with NO and can react with water to form NH3; the NH3 can react with the NO and also can react with NO2; the denitration effect is improved and the denitration rate can reach 95 percent or more;when the same denitration effect is realized, the dosage can be reduced when being compared with that of other denitration agents and the denitration cost is reduced.
Description
technical field [0001] The invention belongs to the technical field of flue gas denitrification, and in particular relates to a flue gas denitrification agent. Background technique [0002] Nitrogen oxides (NO X ) is the main air pollutant, which can cause acid rain, photochemical pollution, greenhouse effect and the destruction of the ozone layer. Nitrogen oxides (NO X ) is the flue gas released by coal combustion, which contains a large amount of NO, NO 2 and a small amount of N 2 O, followed by vehicle exhaust. With the development of my country's electric power industry and the popularization of private cars, nitrogen oxides (NO X ) emissions are growing rapidly, control and treatment of nitrogen oxides (NO X ) pollution is imminent, and the denitrification of coal-fired flue gas is to control nitrogen oxides (NO X ) is one of the important measures. [0003] Commonly used denitrification technologies include SCR method and SCNR method. The denitrification effic...
