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 2):
The air purification apparatus of  claim 1 , wherein the primary filter is configured such that:\n a plurality of filtering spaces is formed; the plurality of filtering spaces are divided by first meshes through which contaminated air passes; a first smoke inlet configured to receive the contaminated air and a first smoke outlet configured to discharge the contaminated air after the contaminated air has passed through all the plurality of filtering spaces are provided; bottoms of the plurality of filtering spaces are formed in \u201cV\u201d shapes; a spray pipe disposed over the filtering spaces and spray nozzles configured to connect with the spray pipe and to communicate with the filtering spaces, respectively, are included; a first water pump is provided at one end of the spray pipe, and a limewater tank is connected to the first water pump; transfer rollers are provided at collection locations of the bottoms of the plurality of filtering spaces; hydraulic motors are each provided at one end of each of the transfer rollers, and a hydraulic unit is physically connected to and transfers power to the hydraulic motors; contaminants are separated from the air by limewater sprayed by the spray nozzles in the contaminated air having entered through the first smoke inlet and then fall down, and the air from which the contaminants have been separated is moved toward the first smoke outlet; and the contaminants separated from the air are transferred to a single location by the transfer rollers.
