Solid and liquid two-phase mixture of sea ice, preparation method thereof and sea ice solid-state centrifugation desalinization method

Abstract

The invention discloses a sea ice solid eccentric desalinating method, which comprises the following steps: adopting sea ice; filling ice halogenation compound; proceeding sea ice eccentric desalination; desalinating ice-crystal.

Description

Technical field [0001] The invention relates to a method for producing fresh water raw water. Specifically, it relates to a method for preparing a solid and liquid two-phase mixture of sea ice using sea ice as a raw material, and relates to using the solid and liquid two-phase mixture of sea ice to perform centrifugal desalination when the sea ice is in a solid state. Desalination, the method of preparing fresh water. Background technique [0002] The shortage of fresh water resources is a universal problem worldwide, and the main reason is the shortage of fresh water sources. On the one hand, the coastal areas of northern my country lack fresh water resources, on the other hand, they are adjacent to the northern part of the Bohai Sea and the Yellow Sea and have inexhaustible sea water, sea ice and other resources. Since the salt content in sea water and sea ice (the salinity of sea water is about 32‰ and the salinity of sea ice is about 8‰) is much higher than people's normal us...

AI Technical Summary

Problems solved by technology

Due to the limitations of the technical method itself, it is still difficult to meet the scale demand for water consumption in coastal water-scarce areas on the production scale of a single unit. At the same time, the filtration efficiency is greatly affected by the water temperature on the one hand (the seawater temperature in the northern region is about half a year. The time is lower than the desalination high-efficiency water temperature), and the heating of seawater temperature in the process of desalination and desalination also greatly i
