<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device of a diesel engine superior in exhaust emission control capacity, and easy in maintenance, while minimizing a pressure loss in exhaust gas. <P>SOLUTION: The exhaust gas EG of the diesel engine 11 via an exhaust gas introducing pipe 4 flows in from above a gas-liquid contact mixing part 3. Seawater W supplied to a circulating tank 2 is circulated as a cleaning liquid FW to a lower end part 4a of the exhaust gas introducing pipe 4 via a cleaning liquid circulating passage 6 by a circulating pump 10b, and is sprayed from a tip nozzle 6a, and is violently contacted and mixed by a plurality of blade parts of arranging a large number of spirally rightward or leftward twisted small holes inside a cylindrical body of mixing elements 3a to 3d arranged in a series in the gas-liquid contact mixing part 3. Soot and dust included in the exhaust gas EG are collected in the cleaning liquid FW, and purified exhaust gas CG is exhausted from an exhaust gas exhaust pipe 5 via the circulating tank 2. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
