Description

太阳能溴化锂海水淡化系统Solar Lithium Bromide Seawater Desalination System

技术领域technical field

本实用新型涉及海水淡化技术领域，具体的说，是涉及一种太阳能溴化锂海水淡化系统。The utility model relates to the technical field of seawater desalination, in particular to a solar lithium bromide seawater desalination system.

背景技术Background technique

全球地球表面的72％被水覆盖，但是淡水资源仅占所有水资源的0.75％，地球的储水量比较丰富，但能直接被人们生产和生活利用的很少。世界经济快速发展忽略了淡水资源的保护和利用，同时世界人口的过快增加,导致淡水资源的严重缺乏，这问题在一些地区尤为突出。海水淡化逐渐成为新兴的技术发展趋势。72% of the global earth's surface is covered by water, but fresh water resources only account for 0.75% of all water resources. The earth's water storage is relatively rich, but it can be directly used by people for production and life. The rapid development of the world economy has neglected the protection and utilization of fresh water resources. At the same time, the rapid increase of the world population has led to a serious shortage of fresh water resources, which is particularly prominent in some areas. Seawater desalination has gradually become an emerging technology development trend.

目前，海水淡化一般采用外加高温热源对海水加热产生蒸汽后再利用冷却器对蒸汽进行冷凝来淡化海水，这种装置以高温热源为基础，需要消耗大量常规能源，成本很高。随着太阳能利用技术的发展，利用太阳能溴化锂空调进行海水淡化的装置应运而生。但是，由于其循环加热效率和冷却效率低等问题使得太阳能溴化锂空调海水淡化装置效率低，而且，在无太阳时溴化锂空调系统不能运行，因此该装置受天气因素影响严重，难以大力推广使用。At present, seawater desalination generally uses an external high-temperature heat source to heat seawater to generate steam, and then uses a cooler to condense the steam to desalinate seawater. This device is based on a high-temperature heat source, which consumes a large amount of conventional energy and is very expensive. With the development of solar energy utilization technology, a device for seawater desalination using solar lithium bromide air conditioners has emerged as the times require. However, due to its low cycle heating efficiency and low cooling efficiency, the efficiency of the solar lithium bromide air-conditioning seawater desalination device is low, and the lithium bromide air-conditioning system cannot operate when there is no sun, so the device is seriously affected by weather factors, and it is difficult to vigorously promote it.

When the solar energy is large enough, only the energy absorbed by the solar collector The heat heats the lithium bromide solution through the hot water coil in the low-pressure generator to form a single-effect heat pump system for seawater desalination; when the solar energy is small, turn on the direct-fired high-pressure steam generator and open the control valve to form a double-effect heat pump system. Compared with the existing seawater desalination device using solar lithium bromide air conditioner, it can not only improve the efficiency of seawater, but also has good system adjustability under the influence of solar intensity.
