Description
技术领域 technical field
本实用新型涉及海水淡化技术领域，尤其涉及一种海水淡化的处理设备。 The utility model relates to the technical field of seawater desalination, in particular to a treatment device for seawater desalination.
背景技术 Background technique
地球表面大约有90％多被海水所覆盖，随着淡水资源的不断减少，海水成为社会发展及人们生活用水的主要途径之一。然而，传统海水淡化方法其工程投资高，动力消耗大，设备的操作弹性小。因此，海水淡化技术发展的一个重要目标是降低运行成本，而在运行成本的构成中，能耗所占的比重最大，所以降低能耗是降低海水淡化成本最有效的手段。反渗透海水淡化是目前海水淡化的主流技术之一。在反渗透海水淡化过程中，需要消耗大量的电能提升进水压力来克服水的渗透压，而反渗透膜排出的浓水余压高达5.5～6.5MPa,按照40％的回收率计算，排放的浓盐水中还蕴含约60％的进料水压力能量，将这一部分能量回收变成进水能量可大幅降低反渗透海水淡化的能耗，这一目的的实现有赖于能量回收技术的提高。 About 90% of the earth's surface is covered by sea water. With the continuous reduction of fresh water resources, sea water has become one of the main ways for social development and people's daily water. However, the traditional seawater desalination method has high engineering investment, high power consumption, and low equipment operation flexibility. Therefore, an important goal of the development of seawater desalination technology is to reduce operating costs, and in the composition of operating costs, energy consumption accounts for the largest proportion, so reducing energy consumption is the most effective means to reduce the cost of seawater desalination. Reverse osmosis seawater desalination is one of the mainstream technologies for seawater desalination. In the reverse osmosis seawater desalination process, it is necessary to consume a large amount of electric energy to increase the inlet water pressure to overcome the osmotic pressure of the water, while the residual pressure of the concentrated water discharged by the reverse osmosis membrane is as high as 5.5-6.5 MPa. Calculated according to the recovery rate of 40%, the discharged Concentrated brine also contains about 60% of the feed water pressure energy. Recovering this part of energy into feed water energy can greatly reduce the energy consumption of reverse osmosis seawater desalination. The realization of this goal depends on the improvement of energy recovery technology.
