摘要
针对传统太阳能海水淡化面临的成本高、效率低等问题,指出海水淡化系统中各部件严重分离、能量传输路径冗长、高温太阳能集热技术与海水淡化系统存在不匹配是其主要影响因素。通过探究太阳能热法海水淡化成本与聚光效率、产水率、热性能系数(η_(GOR))等因素的关联关系,指出聚光直接加热、近零热容蒸发、能质梯级利用、能量多次利用、多目的系统以及与用户直接结合是实现太阳能海水淡化技术低成本大规模应用的关键路径。
Aiming at the problems of high cost and low efficiency faced by traditional solar seawater desalination,this study points out that the main influencing factors are the serious separation of various components in seawater desalination systems,the lengthy energy transmission path,and the mismatch between high-temperature solar heat collection technology and seawater desalination systems.By exploring the relationship between the cost of solar thermal seawater desalination and concentrating efficiency,water production rate,thermal performance coefficient η_(GOR) and other factors,it is pointed out that solar concentrating direct heating,near zero heat capacity evaporation,cascade utilization of energy quality,multiple utilization of energy,multipurpose system and direct combination with users are the key paths to realize the low-cost and large-scale application of solar seawater desalination technology.
