By three the described ozone generators arranged in oxidative absorption tower 1 to denitrating tower 2, the ozone that order manufactures 50%, 30%, 20% successively is respectively set by above-mentioned.
In the middle of flue gas, NOx main component is NO (accounting for 95%).NO is insoluble in water, and high-valence state NO
2, N
2o
5deng water soluble.This device is after flue-gas dust-removing and desulfurization, and to a kind of method that NO administers, this method adopts oxidative absorption method, utilizes ozone, as strong oxidizer, NO is oxidized to high price NOx soluble in water, absorbs NOx adding NaOH as absorbent.
Absorption reaction equation is as follows:
2NaOH+2NO＝NaNO
3+NaNO
2+H
2O
2NaOH+NO
2＝2NaNO
3+H
2O
In actual use procedure, first the flue gas after dust-removal and desulfurizing is introduced oxidative absorption tower 1 by pipeline and carry out oxidation processes.Ozone generator 7 now discharge content be 50% ozone and described flue gas react, then mix by during described cyclone mixer 4, after ozone and the NO in described flue gas fully being contacted form high-valence state NOx, reactive absorption is carried out again by the NaOH of atomization, counter direction jet trays 6 makes flue gas secondary response more again by inclined hole, add the reaction time, make reaction more abundant.
Flue gas continues to enter denitrating tower 10 by pipeline, is reacted by identical ozone, and cyclone mixer 4 mixes, and NaOH absorbs again, and counter direction jet trays 6 continues to extend the reaction time.By the oxidative absorption of three times, make the denitration rate of NOx reach more than 90%, thus reach the requirement of national environmental protection method to NOx emission index.
