Abstract:
The present invention relates to an air purification apparatus for a coal-fired electric power plant, and more specifically to an air purification apparatus for a coal-fired electric power plant, which, first, can filter out wastes of contaminated smoke by using limewater, which, second, can filter out fine dust and carbon dioxide included in the smoke, which, third, can convert waste gas including carbon monoxide in a state in which only smoke remains into carbon dioxide by reacting oxygen with the waste gas and purify the smoke into clean air by allowing a sodium hydroxide solution to absorb the carbon dioxide, and which, fourth, can eliminate humidity from the clean air by passing the clean air through a moisture condenser a plurality of times and discharge clean air in a pure smoke state from the power plant.

Claim (Index 1):
An air purification apparatus for a coal-fired electric power plant, the apparatus comprising:\n a primary filter configured to filter out contaminants of contaminated smoke by means of limewater; a secondary filter configured to filter out fine dust and carbon dioxides included in the smoke; a tertiary filter configured to convert the waste gas secondarily filtered and including carbon monoxide into carbon dioxide by reacting oxygen with the waste gas, and to purify the waste gas into clean air by allowing a sodium hydroxide solution to absorb carbon dioxide; and a quaternary filter configured to eliminate humidity by passing the clean air through a moisture condenser a plurality of times, and to discharge clean air in a pure smoke state from a power plant.
