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 4):
The air purification apparatus of  claim 3 , wherein the tertiary filter is configured such that:\n a primary filtration tank and a second filtration tank divided by a partition configured such that a through hole is formed on one side thereof are included; a third smoke inlet connected to the second smoke outlet is provided; a second spray pipe and a plurality of second spray nozzles connected to the second spray pipe are located over or on the primary filtration tank and the second filtration tank, and the second spray nozzles are each configured to communicate with one of the primary filtration tank and the second filtration tank; one end of the second spray pipe is connected to a third water pump and a second pump, and one side of the third water pump is connected to any one of the primary filtration tank and the second filtration tank; a sodium hydroxide solution is accommodated inside the primary filtration tank and the secondary filtration tank, and is circulated through the second spray pipe and sprayed via the second spray nozzles by the third water pump and the second pump; the air having entered through the third smoke inlet is transferred from the primary filtration tank to the secondary filtration tank via a smoke transfer tool, and is discharged through a third smoke outlet; the primary filtration tank is provided with an oxygen inlet configured to feed oxygen; and carbon monoxide included in the air having entered the tertiary filter is converted into carbon dioxide by reacting oxygen with the carbon monoxide, and the carbon dioxide is absorbed into the sodium hydroxide solution accommodated inside the primary filtration tank and the secondary filtration tank while passing through the primary filtration tank and the secondary filtration tank to thus allow clean air to be obtained.
