A seawater desalination device

Abstract

The invention belongs to the field of seawater desalination, and relates to a combined hydrate method seawater desalination technology, a technology for promoting the hydration reaction of hydrogel particles, and a seawater desalination device for continuous production. Cyclopentane hydrate is used as an intermediate product, based on water The porous and hydrophilic properties of the gel particles drive the hydrate reaction. After the hydrate slurry is generated, it enters the trickle flow reactor to continue the reaction. Through the continuous injection of fresh seawater and the continuous discharge of concentrated brine, the residual salt is depleted while the saturation reaction occurs. For washing, the trickle reactor adopts a series semiconductor refrigeration design, thermally decomposes the hydrate in the saturated reaction, and enters the thermal separator to separate cyclopentane, hydrogel fluid and fresh water, and the enhanced mixing effect of the microchannel reactor The reaction efficiency can be further improved; for the first time, the combination of hydrogel particles and cyclopentane is applied to seawater desalination, realizing the high-efficiency continuous production of hydrate seawater desalination under normal pressure, and has the feasibility of industrial application.

Description

A seawater desalination device Technical field: The invention belongs to the technical field of seawater desalination equipment, be specifically related to a kind of seawater desalination device, based on hydrogel micro The technology of promoting the hydration reaction of particles, the salt-removing effect of cyclopentane hydrate and the hydrate method realize the desalination of seawater. Background technique: The freshwater resources on the earth only account for 2% of the total water resources, and 87% of the freshwater is frozen in solid form. In polar glaciers and alpine ice layers, it is difficult for humans to use it, coupled with the uneven distribution of water resources, and the lack of fresh water resources It has become a common challenge faced by people all over the world. Therefore, people turn their attention to the field of seawater desalination. Seawater desalination refers to removing impurities and salt in seawater in a certain way, thereby obta...
