Abstract

The invention belongs to the field of gas hydrate technology application and particularly relates to a sea water desalination method and a two-stage sea water desalination device. The method comprises the following steps: generating a carbon dioxide hydrate from carbon dioxide and sea water by a first-stage sea water desalination system and then resolving the carbon dioxide hydrate so as to obtain fresh water; generating a propane hydrate from propane and sea water by a second-stage sea water desalination system and then resolving the propane hydrate so as to obtain fresh water. The Two-stage sea water desalination device comprises a first-stage sea water desalination device and a second-stage sea water desalination device which are connected in series; each stage of sea water desalination device comprises a gas-liquid supplying and mixing unit, a gas hydrate generating and conveying unit, and a gas hydrate dissociating and resolving unit. The device and the method are high in efficiency, low in energy consumption and easy to achieve.

Description

technical field

[0001] The invention belongs to the application field of gas hydrate technology, and specifically relates to a seawater desalination method and device, which is mainly used for seawater desalination in coastal areas to make up for the shortage of fresh water resources, and can also be used for other liquid concentration purification and high-salt sewage Desalination purification treatment field. Background technique

[0002] The total amount of water on the earth is 1.4 billion cubic kilometers, but the fresh water reserves account for only 2.53% of the global total, and 68.7% of it is distributed in the form of solid glaciers in the hard-to-exploit alpine and southern and northern regions. In the past century, due to population growth, industrial development, and the development of irrigated agriculture, the demand for water resources has soared, and the contradiction between supply and demand of water resources has become prominent. According to statistics...
