Abstract

A device to eliminate particulates contained in exhaust gas ejected from motors, such as diesel engines for ships, surface transportation vehicles and overland fixed diesel engines, and a process to eliminate particulates contained in the exhaust gas are provided.The device of the present invention is a device for eliminating particulates contained in exhaust gas 10 ejected from diesel engines constituted by a discoid-shaped filter 11 used as a capturing means to capture the particulates and sprayers 13 having a plurality of nozzles 13a, such as spray type and shower type, used as a catalyst attaching means to attach an alkaline metal catalyst solution 12 onto the surface of the captured particulates in the discoid-shaped filter 11, and the device attaches the catalyst onto the surface of the captured particulates, and then burns and decomposes the unburned particulates portion in the exhaust gas.
