中文摘要	根据船舶航行气象数据和主机系统在额定工况下的热量衡算,在晃振平台上测试平均孔径为12.205nm的硅胶和复合吸附剂(70%硅胶+30%氯化钙)的水蒸气吸附等温线和吸附取水量.结果表明:晃振不影响硅胶和复合吸附剂吸附水蒸气的性能,制备水都能达到GB5749-2006的指标要求,硅胶吸附取水的水质较好;复合吸附剂在相对湿度较小区域的吸附量较大,但制备淡水稍有咸味、硬度也较高.中孔以上的硅胶可作为船舶吸附取水的吸附剂.; Extracting water from air in ship’s environment was evaluated based on energy balance among different parts of the main engine system working at the nominal working condition. Silica gel in a mean pore width 12.205 nm was selected to synthesize the composite adsorbent by introducing potassium chloride about 30% in weight, adsorption isotherms of water vapor and the extracted amount of water on the silica gel and the composite were then measured at ambient temperature upon a platform vibrating and swaying in frequencies similar to those on board the ship. Results show that the waste heat of the steam from the exhaust gas boiler and the jacket cooling water was enough to power the extracting unit, and indices of the extracted water from silica gel and the composite were all met with the requirements set by the national standard of China (GB5749-2006). Results also reveal that vibrating and swaying of the platform impacted little on the adsorptive performance of the water vapor on the silica gel and the composite; the composite performed better in water vapor adsorption while in a lower relative humidity, however, the resulted water tasted some of salty and had a higher degree of hardness due to the dissolution of the potassium chloride. Conclusions are drawn that the silica gel with a pore size larger than meso-pore can directly be used as the adsorbent for on board extracting unit.; 【作者单位】集美大学轮机工程学院福建省船舶与海洋重点实验室；【作者英文名】ZHENG Qing-rong, PAN Qi-yong, XIE Chen, Zhi HUI-jie (Provincial Key Laboratory of Naval Architecture & Ocean Engineering, Institute of Marine Engineering, Jimei University, Xiamen 361021, China)
