长航6000 m^3耙吸挖泥船柴油机排放控制系统配置分析

Configuration Analysis of Emission Control System in Diesel Engine on Changhang 6 000 m^3 Trailing Suction Dredger

随着世界范围对于环保的要求日益提高,柴油机废气中的氮氧化物及硫氧化物作为大气污染一大来源,其排放控制日益受到用船方的关注,柴油机的废气处理现已有多种技术方案可以应对。文中以长航6000m^3自航耙吸挖泥船作为研究对象,分析可行的废气处理及排放控制方案,并进一步分析其对于船舶总体布置的影响。

With the increasing requirements of the environmental protection in the world, nitrogen oxides （NOX）and sulfur oxides （SOX） in the exhaust gas from the diesel engine are the major sources of atmospheric pollution. The emission control of NOX and SOx is increasingly concerned by the ship owner. The exhaust gas from a diesel engine can be handled by the various technical methods nowadays. This paper analyzes the feasible exhaust gas treatment and emission control schemes of a 6 000 m^3 self-propelled trailing suction dredger and the impact on the general arrangement of the dredger.
