Abstract

The invention discloses a gas-hydrate-method seawater desalination system. The gas-hydrate-method seawater desalination system has the advantages that gas recycling between a first reaction kettle anda second reaction kettle is achieved, gas hydrate can be generated through gas and seawater so as to achieve seawater desalination to generate desalted water, and seawater desalination degree is increased greatly; a pressurizing system is arranged on a pipeline system, and the pressure of a gas hydration reaction system can be regulated through the piston pressurizing system so as to increase seawater desalination efficiency; in general, the gas hydrate generated by the gas and the seawater is decomposed to obtain the desalted water, seawater desalination is achieved, the seawater desalination effect can be greatly improved by the system, cost can be lowered, and the system is worthy of popularization and application.

Description

Technical field

[0001] The invention relates to the technical field of seawater desalination, in particular to a seawater desalination system using a gas hydrate method. Background technique

[0002] As a scarce basic resource, freshwater resources have a very important impact on people's production and life. At present, the shortage of freshwater resources in the world is becoming more and more serious. The shortage of freshwater resources has become the focus of attention of all countries in the world. Desalination is a method of separating salt and water in seawater to obtain fresh water, which can provide a stable freshwater resource supplement. Therefore, seawater desalination technology has become an effective way to solve the problem of shortage of freshwater resources.

[0003] The existing seawater desalination methods mainly include distillation, freezing, reverse osmosis, electrodialysis, ion exchange, solvent extraction, etc., but these methods are limited by cost, te...
