船用柴油发动机产生含有大量SOx和颗粒物（PM）的废气，并且已经颁布法律来规范船舶废气排放。本文提出了一种能够同时去除SO2和颗粒物（PM）的U型废气净化（EGC）系统。本研究的目的是寻找EGC系统去除效率与参数之间的关系，从而得到最佳的结构和操作参数。实验结果表明，在实验操作条件范围内，洗涤塔内SO2吸收率主要受液气比、pH值和温度的影响。为了使系统稳定运行，液气比和温度确定后，pH值必须在6.5~7.5的固定范围内。针对船舶适用的EGC系统也进行了进一步的研究。在SO2去除效率的基础上，对颗粒物（PM）的预测和实验验证进行了研究。什么时候 ...
Marine diesel engines produce exhaust gas including a lot of SOx and particulate matter (PM), and laws have been promulgated to regulate ship exhaust emissions. This paper proposes a U-type exhaust gas cleaning (EGC) system that is capable of removing SO2 and particulate matter (PM) simultaneously. The purpose of this study was to find the relationships between removing efficiency and parameters of EGC system, then get the optimal structural and operational parameters. The experimental results show that the SO2 absorption rate in the scrubber was mainly influenced by liquid–gas ratio, pH value, and temperature in the range of experimental operating conditions. With the system stable running, when the liquid–gas ratio and temperature were determined, the pH value must be in a fixed range of 6.5–7.5. The further research was also carried on for the EGC system applicable to ships. On the basis of SO2 removal efficiency, the prediction and experimental validation of particulate matter (PM) were studied. When ...
