Method for the Simultaneous Removal of Nitrogen Oxides and Sulfur Dioxide using Ozone Oxidation and Wet Scrubber

摘要

The present invention relates to a method for simultaneously removing nitrogen oxides and sulfur oxides using ozone oxidation and a wet scrubber, and more particularly, to a method for removing oxygen oxides and sulfur oxides using a gas removing apparatus including an ultrasonic humidifier for supplying hydrogen peroxide droplets, an ozone feeder, (Step 1) of oxidizing the nitrogen oxides and the sulfur oxides by supplying a mixed gas of nitrogen oxides and sulfur oxides and ozone to the gas phase reactor, And a step (step 2) of absorbing and removing the mixed gas oxidized in step 1 through the wet scrubber into a droplet having a size of 60 to 90 mu m in hydrogen peroxide concentration of 0.1 to 5.0 mol / L (step 2) (Step 2). / RTI In the method of removing nitrogen oxides and sulfur oxides according to the present invention, when the nitrogen oxide and the sulfur oxide gas are removed using the ozone oxidation and wet scrubber of the present invention, the waste gas is removed in two steps, and an ultrasonic humidifier By spraying hydrogen peroxide in a wet scrubber, it is possible to remove nitrogen oxides and sulfur oxides with good removal efficiency.
