Abstract

The invention discloses a sea water desalination device, which relates to the technical field of sea water desalination. The interior of a tank is provided with a cavity, the sidewall is provided withone or two openings, and the openings are closed by cover plates; an evaporator is arranged in the cavity and distanced from the wall of the cavity, the evaporator comprises a primary liquid-absorbing layer and pipelines buried in the primary liquid-absorbing layer, and both the inlets and outlets of the pipelines pass through the cover plates to communicate with the outside; at least one layer of secondary evaporation layer is concentrically arranged around the periphery of the evaporator, and is spaced for a predetermined distance, and the secondary evaporation layer consists of a condensing plate and a secondary liquid-absorbing layer which are in tight contact; both the primary liquid-absorbing layer and the secondary liquid-absorbing layer are a porous material, at least the part, which is in contact with the primary liquid-absorbing layer and the secondary liquid-absorbing layer, of one or two cover plates is the porous material, and pores in the primary liquid-absorbing layer,the secondary liquid-absorbing layer and the cover plates communicate with one another. The sea water desalination device can sufficiently recycle residual heat, so that the water production ratio isincreased, and water can still be stably and efficiently produced under a shaking state.

Description

technical field [0001] The invention relates to the technical field of seawater desalination, in particular to a seawater desalination device. Background technique [0002] The marine nuclear power platform is an organic combination of marine engineering and nuclear energy engineering. It is used to provide resources such as electricity and fresh water. It is a green energy equipment that is urgently needed for my country's ocean development. During the operation of nuclear power platforms, a large amount of waste heat will be generated. At present, the waste heat is mostly used for heating, but the heating cycle is limited by the season and is short. In the non-heating cycle, the ocean is usually used as a heat well to discharge a large amount of waste heat directly to the seawater. , causing serious thermal pollution to the sea environment. With the gradual strengthening of the global awareness of environmental protection in sea areas, the problem of waste heat emission h...
