    • Provided is a marine diesel engine exhaust gas treatment system capable of reliably removing a particulate matter and sulfur oxides contained in exhaust gas emitted from a marine diesel engine. The marine diesel engine exhaust gas treatment system includes: an electrostatic precipitator apparatus (7) that collects a PM of exhaust gas emitted from the marine diesel engine; a seawater scrubber (9) that sprays seawater to the exhaust gas from which the PM is removed by the electrostatic precipitator apparatus, to remove SOx from the exhaust gas; an exhaust gas component detector (LA3) that detects a component of the exhaust gas treated by the electrostatic precipitator apparatus and the seawater scrubber; a seawater component regulator (9C) that recovers the seawater sprayed by the seawater scrubber, to perform component regulation on the recovered seawater; a seawater circulator (9D) that returns, to the seawater scrubber, the seawater that is subjected to the component regulation by the seawater component regulator; and an exhaust gas treatment controller that regulates an operating state of the electrostatic precipitator apparatus and an operating state of the seawater scrubber in such a manner that a component remaining in the exhaust gas that is detected by the exhaust gas component detector falls within a prescribed range.
    • 提供一种能够可靠地除去从船用柴油发动机排出的废气中所含的颗粒物质和硫氧化物的船用柴油发动机废气处理系统。 船用柴油机排气处理系统包括:收集从船用柴油发动机排出的废气的PM的静电除尘器装置(7); 一个海水洗涤器(9),其将海水喷射到通过静电除尘器装置从其中除去PM的废气,以从废气中除去SOx; 检测由所述静电除尘器装置和所述海水洗涤器处理的废气的成分的废气成分检测器(LA3); 海水部件调节器(9C),其回收由海水洗涤器喷射的海水,以对回收的海水进行部件调节; 海水循环器(9D)将海水部件调节器进行部件调节的海水返回到海水洗涤器; 以及废气处理控制器,其以这样的方式调节静电除尘器装置的操作状态和海水洗涤器的操作状态,使得由排气分量检测器检测到的废气中残留的成分落在规定范围内 。
