废气清洗脱硫装置在船舶设计中的应用分析

Analysis on the Application of Waste Gas Cleaning and Desulfurization Device in Ship Design

基于有效实施国际海事组织2020年1月1日起全球船用燃油限硫的规定,阐述了废气清洗脱硫装置在船舶上的应用背景和规则实施的有效时间,以便船厂对安装废气清洗脱硫装置的周期进行有效评估。通过分析开式、闭式、混合这3种脱硫系统工作原理及优缺点,重点指出了开式脱硫装置在设计过程中可能遇到的难点和部分注意事项并做了要点分析。

Based on the effective implementation of the International Maritime Organization′s regulations on sulfur limitation of global marine fuel oil since January 1,2020,the application background of the waste gas cleaning and desulfurization device on the ship and the effective time of the implementation of the rules are described,so that the shipyard can effectively evaluate the period of installing the waste gas cleaning and desulfurization device.By analyzing the working principle,advantages and disadvantages of three kinds of desulfurization systems,i.e.open type,closed type and mixed type,this paper mainly points out the difficulties and some points for attention that may be encountered in the design process of open type desulfurization device,and analyzes the key points.
