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 3):
The air purification apparatus of  claim 2 , wherein the secondary filter is configured such that:\n a limewater filtration tank and a sodium bicarbonate and limewater filtration tank divided by a second mesh and a partition are included; the limewater filtration tank is provided with a second smoke inlet connected to the first smoke outlet; the sodium bicarbonate and limewater filtration tank is provided with a second smoke outlet configured to discharge the air; bottoms of the limewater filtration tank and the sodium bicarbonate and limewater filtration tank are formed in \u201cV\u201d shapes, and first discharge plates are provided in the limewater filtration tank and second discharge plates are provided in the sodium bicarbonate and limewater filtration tank; one of the first discharge plates and one of the second discharge plates are disposed on tops of the \u201cV\u201d-shaped bottoms of the limewater filtration tank and the sodium bicarbonate and limewater filtration tank, respectively; a remaining one of the first discharge plates and a remaining one of the second discharge plates are disposed in upper portions of the limewater filtration tank and the sodium bicarbonate and limewater filtration tank at a height which enables a temporary limewater tank and a temporary sodium bicarbonate and limewater filtration tank to be formed; a limewater tank and a sodium bicarbonate and limewater tank are connected to the bottoms of the limewater filtration tank and the sodium bicarbonate and limewater filtration tank, respectively; each of the limewater tank and the sodium bicarbonate and limewater tank is connected to a second water pump and a first pump; transfer belts are provided on the tanks, respectively, and transfer impurities, separated from the air in the secondary filter, from the tanks to an outside; in the secondary filter, limewater and sodium bicarbonate and limewater are respectively fed from the limewater tank and the sodium bicarbonate and limewater tank when the incoming air passes through the filtration tanks and are respectively collected in the temporary limewater tank and the temporary sodium bicarbonate and limewater tank, the collected limewater and the collected sodium bicarbonate and limewater each separate impurities included in the air while falling through a plurality of through holes formed in a corresponding one of the discharge plates, and the separated impurities, the limewater, and the sodium bicarbonate and limewater each enter a corresponding one of the limewater tank and the sodium bicarbonate and limewater tank; and the impurities are discharged by the transfer belts, and the limewater and the sodium bicarbonate and limewater are returned to the temporary limewater tank and the temporary sodium bicarbonate and limewater tank, respectively, through the second water pump and the first pump.
