Sea floating type sea water desalination device

Abstract

The invention provides a sea floating type sea water desalination device. A sea water desalination structure is arranged in a cylindrical shell; a permanent magnet direct current generator is also arranged in the shell; the sea water desalination device comprises a first flowmeter, a first booster pump, a multi-medium filter, an ion exchanger, a precise filter, a second booster pump, a primary reverse osmosis membrane, a second flowmeter, a third booster pump and a secondary reverse osmosis membrane which are sequentially connected in series through pipelines; a fifth water outlet in the secondary reverse osmosis membrane is connected with a second water outlet; and the sea water desalination device also comprises a magnetic suspension type wind driven generator. The sea floating type seawater desalination device provided by the invention comprehensively utilizes wind energy and wave energy of a sea and solves the problem of energy consumption of the device. The device can be fixed ona certain sea area and moved to a platform; and when destructive force of a sea approaches to the bearing limit of the device, the device can be moved to a safe position so as to avoid load impact. Of course, the floating movable seawater desalination device can be used for leasing and capital investment is reduced.

Description

technical field [0001] The invention relates to a seawater desalination device, in particular to an ocean floating seawater desalination device. Background technique [0002] With the prosperity of international trade and the exploration and development of marine resources, people drifting in the vast ocean have an increasing demand for fresh water resources. How to obtain fresh water resources from high-salinity seawater encountered this problem in the age of great navigation in the world. Up to now, seawater has been desalinated in different ways. There is a simple distillation method: evaporating seawater at high temperature into water vapor, and then condensing it into liquid fresh water, which consumes a lot of energy and has a lot of scale, but the amount obtained is very small; Seawater, when the liquid fresh water turns into ice, the salt is separated, consumes a lot of energy, and the taste of fresh water is not good; and the reverse osmosis method that uses semi-p...

Problems solved by technology

However, for ships with low economic benefits, storing too much fresh water on the ocean will not only greatly increase the fuel supply and increase the ship's navigation resistance, reduce the speed of navigation, but also reduce the storage capacity.
