WET TYPE ROAD SWEEPING VEHICLE CAPABLE OF REDUCING EXHAUST GAS OF AUXILLIARY ENGINE

摘要

According to an embodiment of the present invention, provided is a wet-type road sweeping vehicle capable of reducing exhaust gas of an auxiliary driving engine comprising: a loading unit which allows impurities of a surface of a road to be inserted therein and accommodates the impurities; a main duct which is formed on an upper side of the loading unit and forms a path to enable air current, which mixes the impurities accommodated in the loading unit with air, to move; a filter housing which is formed to have a predetermined length in the direction of a vehicles width and communicates with the main duct through a filter inlet formed on one end portion in a lengthwise direction; a water spraying nozzle which sprays water to the air current from an inner wall of the filter housing; a plurality of separation walls which divide an inner space of the filter housing into at least two areas in a lengthwise direction; vortex generation members which are arranged in a vertical direction in each area and are alternately formed in a lengthwise direction of the filter housing; a plurality of tubes which are horizontally formed to penetrate a pair of the separation walls, facing each other, among the separation walls, are arranged to be separated from each other in a vertical direction, and transfer the air current to a next area; a discharge hole which transfers the air current, having been transferred to the next area, to a previous area of an upper stream side; an auxiliary driving engine which generates suction force in the filter housing; and a connection pipe which connects an exhaust pipe of the auxiliary driving engine to the filter inlet.
