典型航线船舶排放清单及排放特征研究

文章分析了我国典型航线典型船舶排放特征,以船舶自动识别系统数据为基础,收集整理所选研究船舶排放参数,结合船舶实际航行资料,采用动力法估算了秦皇岛港—广州港航线某散货船一个航行周期的排放清单,并分析了靠港、停泊、港内机动、巡航4个船舶状态下的排放特征,绘制了2 km×2 km分辨率的空间排放特征图。结果表明,该典型航线上典型散货船舶一个航行周期排放的SOx、NOx、PM10、PM2.5总量分别为18.88吨、30.87吨、1.85吨和1.69吨。排放源分析表明从在船舶的主机、辅机和锅炉3种排放源中,主机是主要排放源。航行状态上巡航工况排放量最大;船舶排放污染物的空间分析表明,船舶在进出港口区域是污染物排放最密集的区域。

Typical Route Ship Emission Inventory and Emissions Characteristics

For the analysis of the typical routes typical ship emission characteristics, This study based on the data system of automatic identification system, Collect the selected research discharge parame-ters of the ship, with the reality of ship navigation information, Calculated the Qinhuangdao port--Guangzhou port sailing routes a bulk carrier a cycle emissions listing by the Activity-based approach, and analysis of the different working condition of discharge characteristics of the ship, and raw 2 km×2 km resolution space emission characteristic figure. The results show that the a voyage cycle emission amount of SOX and NOX,and PM10 and PM2.5,respectively 18.88 t、30.87 t、1.85 t和1.69 t. Emis-sion source analysis indicated that the engine is the major source of the ship. Cruise condition is the big-gest emission source in a sail cycle. The port is nearby is the most densely area of ship emission.
