Abstract

The invention belongs to the field of seawater desalination, and relates to a seawater desalination device integrating a hydrate method seawater desalination technology, a promotion technology of hydrogel particles on hydration reaction and continuous production. A cyclopentane hydrate is used as an intermediate product, a hydrate is driven to react based on the porous and hydrophilic characteristics of hydrogel particles, and hydrate slurry is generated and then enters a trickle reactor to continue to react. Through continuous injection of fresh seawater and continuous discharge of strong brine, residual salt is washed while a saturation reaction occurs, a trickle reactor adopts a serial semiconductor refrigeration design, the hydrate of the saturation reaction is subjected to thermal decomposition, and cyclopentane, hydrogel fluid and fresh water are separated after the hydrate enters a thermal separator; the reaction efficiency can be further improved through the enhanced mixing effect of the micro-channel reactor; and the hydrogel particles and the cyclopentane are combined and applied to seawater desalination for the first time, efficient and continuous production of hydrate-method seawater desalination under normal pressure is achieved, and industrial application feasibility is achieved.

Description

Technical field: [0001] The invention belongs to the technical field of seawater desalination equipment, and in particular relates to a seawater desalination device, which realizes desalination of seawater based on the technology for promoting hydration reaction of hydrogel particles, the salt removal effect of cyclopentane hydrate and the hydrate method. Background technique: [0002] The fresh water resources on the earth only account for 2% of the total water resources, and 87% of the fresh water is frozen in the polar glaciers and alpine ice sheets in solid form, which is difficult for humans to use. In addition, the spatial distribution of water resources is uneven , the lack of fresh water resources has become a common challenge faced by people all over the world. Therefore, people turn their attention to the field of seawater desalination. [0003] Seawater desalination refers to the removal of impurities and salt in seawater in a certain way, so as to obtain fresh w...
