Abstract
An air purifying apparatus includes an air flow generating device for generating a flow of air, a nozzle spraying water to the air flowing through the air flow generating device, a plasma module performing a plasma reaction on the air containing the water sprayed from the nozzle, and oxidizing NOx in the air and converting it into NO3, an eliminator eliminating the NO3 converted in the plasma module and the water contained in the air and passing pure air through the eliminator and out of the air purifying apparatus and a water tank storing the water received from the eliminator, thereby heightening the removal efficiency of NOx from the air.
Claims17
An apparatus for purifying air, comprising:
- an air flow generating device for generating a flow of air;
- a nozzle spraying water to the air flowing through the air flow generating device;
- a plasma module performing a plasma reaction on the air containing the water sprayed from the nozzle, and oxidizing NOx in the air and converting it into NO3;
- an eliminator eliminating the NO3 converted in the plasma module and the water contained in the air and passing pure air through the eliminator and out of the air purifying apparatus;
- and
- a water tank storing the water received from the eliminator.
A method of removing NOx, comprising:
- converting the NOx in air into NO3 through a plasma reaction, wherein NOx is converted into the NO3 in the plasma reaction b oxidizing the NOx using ozone to produce the NO3 having a relatively high water solubility;
- and
- then subsequently removing the NO3 from the air.
A method of purifying air, comprising:
- generating a flow of air;
- spraying water to the air;
- performing a plasma reaction on the air containing the water, and oxidizing NOx in the air and converting it into NO3;
- and
- eliminating the water and the NO3 contained in the air and passing pure air.
