【摘要】：由于淡水资源的紧缺，海水淡化技术近半个世纪以来得到了迅猛的发展，世界上已经形成了以蒸馏法和膜法为主导的海水淡化技术，该技术为解决淡水资源的短缺问题提供了一条有效途径。然而，，随着海水淡化技术的日益发展，其带来的环境问题也越来越不容忽视。长期以来，海水淡化副产物浓盐水的直接排放或未充分利用对环境带来了相当程度的负面影响，浓盐水的大量排放导致局部海水盐度增加，同时也造成了浓盐水携带的余热在一定程度上的浪费。除此之外，在全球能源紧张的情况下，蒸馏法和膜法海水淡化工艺带来的能源消耗问题也越来越引起人们的重视，世界各国都在探索新能源的开发及与海水淡化相结合的良好应用。太阳能作为清洁可再生能源中的一种，其与海水淡化技术及其副产业相结合的模式正成为业内竞相研究的热点。本文提出了将太阳能与海水淡化及浓盐水电解过程相结合的共生模式的构建，阐述了通过太阳能光伏发电系统对海水淡化及浓盐水电解装置进行供电，同时充分利用太阳能的光热能量对海水进行淡化处理这一系统的组成，并通过设备的构建进行了实验。本文还通过对传统的盘式太阳能蒸馏器的能量流动分析，设计了主动-芯型太阳能海水淡化装置的组成，并对该装置下的海水淡化实验过程与结论进行了分析。通过淡化装置在运行过程中表现出的几点现存缺陷，得出了淡化装置的拟深入优化方案，并在此基础上构思了新一代的太阳能海水淡化装置。本文为太阳能海水资源化及其共生模式的后续研究，以及其中的海水淡化装置的深入设计提供了一定的参考作用。
[Abstract]:Because of the shortage of fresh water resources, seawater desalination technology has been developed rapidly in the past half century. The desalination technology with distillation and membrane technology has been formed in the world. This technology provides an effective way to solve the shortage of fresh water resources. However, with the development of seawater desalination technology, the environmental problems brought by the technology can not be ignored for a long time. The direct discharge or underutilization of the by-product of seawater desalination has a considerable negative impact on the environment, and a large amount of concentrated salt water discharge leads to an increase in the salinity of local seawater. It also causes some waste of waste heat carried by concentrated brine. In addition, in the face of global energy stress. The energy consumption caused by distillation and membrane desalination has attracted more and more attention. Countries all over the world are exploring the development of new energy and its good application combined with seawater desalination. Solar energy is one of the clean and renewable energy sources. Its combination with seawater desalination technology and its secondary industries is becoming a hot spot in the industry. In this paper, a symbiotic model combining solar energy with seawater desalination and concentrated salt water electrolysis process is proposed, and the power supply of seawater desalination and concentrated salt water electrolysis unit through solar photovoltaic power generation system is expounded. At the same time, the system of desalination of seawater is made full use of solar energy, and the experiment is carried out through the construction of equipment. The energy flow analysis of the traditional disk solar distillation is also carried out in this paper. The composition of the active core solar desalination device is designed, and the experimental process and conclusion of seawater desalination under the device are analyzed. Based on this, a new generation of solar desalination equipment is proposed. This paper is a follow-up study of solar water resource utilization and its symbiotic model. And the further design of seawater desalination equipment provides a certain reference.
