The present invention relates to an exhaust gas purification apparatus which can remove harmful components and can also reduce noise of an engine. An exhaust gas purification apparatus according to the present embodiment may comprise: a case which has an inner space therein, and which has openings in a top and bottom thereof; a base which is coupled to close the opening formed in the bottom of the case, and which includes an input tube adapted to enable exhaust gas to be supplied to the inner space of the case therethrough; a guide plate which is disposed inside the inner space of the case at a location spaced apart from the base by a predetermined distance; a collection tube whose one end is coupled to the guide plate, whose other end is coupled to the opening formed in the top of the case, and whose side surface is provided with a plurality of through holes; a plurality of peripheral spray tubes which are disposed on a surface surrounding the collection tube, and in which a plurality of peripheral spray nozzles are formed on a surface opposite to the collection tube; a central spray tube which is disposed at a center of the collection tube, and in which a plurality of central spray nozzles formed to be directed toward an inside surface of the collection tube are formed; and a screw-shaped guide plate whose one end is coupled to a top of the case, whose other end is coupled to a top of the guide plate, and which guides influent exhaust gas via the input tube in a vortex form. |
