【摘要】：随着全球经济的发展,营运船舶的数量不断增加,船舶废气污染物排放的问题也日益加重,欧美许多国家沿海区域都划分出污染物排放控制区,以控制海域内污染物排放。在我国航运业飞速发展的背景下,对船舶污染物排放进行评估的工作变得越来越重要,针对污染物排放评估的研究和探讨也随之深入化。对船舶废气污染物排放进行评估和分析能够使得船舶对环境造成的污染有更加直观的体现,对实现废气减排有很重要的意义。本文针对船舶废气污染物排放评估方法,探讨了影响船舶废气污染物排放的主要因素,采用劳氏船级社通过1995年劳式工程服务中心多方面燃油分析推导出来的排放系数,根据不同船舶工况下的排放系数来计算船舶的废气排放量。建立了船舶主机功率估算模型,通过查询网格数据库中船舶参数计算船舶航行时所受阻力,根据螺旋桨推进系数估算船舶主机有效功率,并对模型进行实例计算验证。建立基于Arc GIS的污染物排放评估模型。利用单元网格内船舶参数和船舶航次信息,计算出特定某一时段船舶的废气排放量,结合特定海域内网格划分信息以及交通流体现的船舶位置信息,计算海域内按网格划分的不同区域排放总量。采用Microsoft Visual Studio2010作为开发环境,开发语言为C#设计污染物排放计算模型。将污染物排放计算模型结合Arc GIS可视化功能,实现基于交通流船舶排放量平面可视化显示。本文以台湾海峡西部海域的船舶信息和网格划分信息进行调试,实现该海域内NOX排放量的可视化显示。
[Abstract]:With the development of the global economy, the number of ships in operation is increasing, and the emission of pollutants from ships is becoming more and more serious. Many coastal areas in Europe and America have been divided into pollutant emission control areas to control the emission of pollutants in the sea area. With the rapid development of shipping industry in China, the assessment of marine pollutant emissions becomes more and more important, and the research and discussion of pollutant emission assessment become more and more in-depth. The assessment and analysis of ship exhaust pollutant emission can make the pollution caused by ship to the environment more intuitionistic, and it is of great significance to realize the emission reduction of exhaust gas. In this paper, the main factors affecting the emission of ship exhaust pollutants are discussed, and the emission coefficients derived by the Lloyd's Classification Society through the analysis of various aspects of fuel oil in the service center of the laborer engineering in 1995 are discussed in the light of the emission assessment method of ship exhaust gas pollutants. The exhaust emissions of ships are calculated according to the emission coefficient of different ship working conditions. The ship mainframe power estimation model is established. The ship resistance is calculated by querying the ship parameters in the grid database, and the effective power of the ship mainframe is estimated according to the propeller propulsion coefficient, and the model is verified by an example. The pollutant emission assessment model based on Arc GIS is established. Using the ship parameters and ship voyage information in the cell grid, the exhaust gas emissions of the ship at a certain period of time are calculated, combined with the information of grid division in the specific sea area and the position information of the ship reflected by the traffic flow. To calculate the total amount of discharge in different areas divided by grid in the sea area. Microsoft Visual Studio2010 is used as the development environment, and C # is used to design the pollutant emission calculation model. The pollutant emission calculation model is combined with the visualization function of Arc GIS to realize the visualization of ship emission based on traffic flow. In this paper, the ship information and grid information of the western Taiwan Strait are used to realize the visualization of NOX emissions in the sea area.
