Abstract
Atmospheric pollutants are efficiently separated from exhaust gas with low operating cost. The exhaust gas cleaning method forms a fine mist of aqueous alkaline solution with an atomizer in an atomizing step; mixes the aqueous alkaline solution mist with exhaust gas to absorb atmospheric pollutants contained in the exhaust gas into the mist in a mixing step; and separates mist that absorbed atmospheric pollutants from the exhaust gas in a separating step.

A method for cleaning exhaust gas that separates atmospheric pollutants from exhaust gas, the method comprising:
- an atomizing step that forms an aqueous alkaline solution mist with an atomizer;
- a mixing step that mixes the aqueous alkaline solution mist with exhaust gas to absorb atmospheric pollutants contained in the exhaust gas into the mist;
- and
- a separating step that separates the mist, which absorbed atmospheric pollutants in the mixing step, from the exhaust gas,
- wherein the atomizer ultrasonically vibrates the aqueous alkaline solution to form mist in the atomizing step.
A method for cleaning exhaust gas that separates atmospheric pollutants from exhaust gas, the method comprising:
- an atomizing step that forms an aqueous alkaline solution mist with an atomizer;
- a mixing step that mixes the aqueous alkaline solution mist with exhaust gas to absorb atmospheric pollutants contained in the exhaust gas into the mist;
- and
- a separating step that separates the mist, which absorbed atmospheric pollutants in the mixing step, from the exhaust gas,
- wherein the atomizer sprays aqueous alkaline solution spray from nozzles and atomizes that spray via static electricity to form mist in the atomizing step.
An apparatus for cleaning exhaust gas that separates atmospheric pollutants from exhaust gas, the apparatus comprising:
- an atomizer that atomizes aqueous alkaline solution to form mist;
- a mixer that mixes mist generated by the atomizer with exhaust gas to absorb atmospheric pollutants contained in the exhaust gas into the mist;
- and
- a separator that separates the mist, which absorbed atmospheric pollutants in the mixer, from the exhaust gas,
- wherein the atomizer is an ultrasonic atomizer that ultrasonically vibrates the aqueous alkaline solution to form mist.
An apparatus for cleaning exhaust gas that separates atmospheric pollutants from exhaust gas, the apparatus comprising:
