【摘要】：由于淡水資源的緊缺，海水淡化技術(shù)近半個(gè)世紀(jì)以來(lái)得到了迅猛的發(fā)展，世界上已經(jīng)形成了以蒸餾法和膜法為主導(dǎo)的海水淡化技術(shù)，該技術(shù)為解決淡水資源的短缺問(wèn)題提供了一條有效途徑。然而，，隨著海水淡化技術(shù)的日益發(fā)展，其帶來(lái)的環(huán)境問(wèn)題也越來(lái)越不容忽視。長(zhǎng)期以來(lái)，海水淡化副產(chǎn)物濃鹽水的直接排放或未充分利用對(duì)環(huán)境帶來(lái)了相當(dāng)程度的負(fù)面影響，濃鹽水的大量排放導(dǎo)致局部海水鹽度增加，同時(shí)也造成了濃鹽水?dāng)y帶的余熱在一定程度上的浪費(fèi)。除此之外，在全球能源緊張的情況下，蒸餾法和膜法海水淡化工藝帶來(lái)的能源消耗問(wèn)題也越來(lái)越引起人們的重視，世界各國(guó)都在探索新能源的開(kāi)發(fā)及與海水淡化相結(jié)合的良好應(yīng)用。太陽(yáng)能作為清潔可再生能源中的一種，其與海水淡化技術(shù)及其副產(chǎn)業(yè)相結(jié)合的模式正成為業(yè)內(nèi)競(jìng)相研究的熱點(diǎn)。 本文提出了將太陽(yáng)能與海水淡化及濃鹽水電解過(guò)程相結(jié)合的共生模式的構(gòu)建，闡述了通過(guò)太陽(yáng)能光伏發(fā)電系統(tǒng)對(duì)海水淡化及濃鹽水電解裝置進(jìn)行供電，同時(shí)充分利用太陽(yáng)能的光熱能量對(duì)海水進(jìn)行淡化處理這一系統(tǒng)的組成，并通過(guò)設(shè)備的構(gòu)建進(jìn)行了實(shí)驗(yàn)。本文還通過(guò)對(duì)傳統(tǒng)的盤(pán)式太陽(yáng)能蒸餾器的能量流動(dòng)分析，設(shè)計(jì)了主動(dòng)-芯型太陽(yáng)能海水淡化裝置的組成，并對(duì)該裝置下的海水淡化實(shí)驗(yàn)過(guò)程與結(jié)論進(jìn)行了分析。通過(guò)淡化裝置在運(yùn)行過(guò)程中表現(xiàn)出的幾點(diǎn)現(xiàn)存缺陷，得出了淡化裝置的擬深入優(yōu)化方案，并在此基礎(chǔ)上構(gòu)思了新一代的太陽(yáng)能海水淡化裝置。本文為太陽(yáng)能海水資源化及其共生模式的后續(xù)研究，以及其中的海水淡化裝置的深入設(shè)計(jì)提供了一定的參考作用。
[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.
