PURPOSE: A split demister device for rotationally removing adhesion materials is provided which is positioned inside an upper part of scrubber for removing ammonia in coke oven gas in gas purifying operation so as to remove the impurities easily when impurities are stuck to demister. CONSTITUTION: The split demister device comprises first, second and third demisters(33,34,35) which are rotationally dividingly installed in an inner space of an upper part of scrubber with center of the first, second and third demisters(33,34,35) being fixed to first, second and third rotation shafts(25,27,31), and an upper part of which an injection nozzle member is installed, wherein the first, second and third rotation shafts(25,27,31) are rotationally installed at the scrubber by a packing bearing member(60) with being projected to an outer part of both sides of the scrubber by passing through an upper part of the scrubber; a demister rotation part(62) comprising a driving motor(21) installed on an outer part of the scrubber with being power connected to driving pulley(23) of the first rotation shaft(25), first driven sprocket(28) of the second rotation shaft(27) power connected to driving sprocket(24) of the first rotation shaft(25), and third driven sprocket(32) of the third rotation shaft(31) power connected to second driven sprocket inserted and fixed to the second rotation shaft(27); and a demister return part(61) comprising a spline boss on which spline guiding surface and spline guiding groove for guiding a straight line type spline formed at an end part of one side of the second rotation shaft(27) are formed, and which is inserted into a guide fixed to device base installed at the outside of the scrubber, and an air cylinder axially connected to a rear part of the spline boss and fixed to a rear surface part of the device base.
