An overflow type continuous hydrate seawater desalination device

Abstract

The invention belongs to the technical field of hydrate application, and discloses a spillover type continuous hydrate seawater desalination device. The spillover type continuous hydrate seawater desalination device comprises a reactor, a hydrate dissociation device, a spraying system, a gas circulating system, a water circulating system and a high-concentration seawater recycling system. A hydrate is separated from a solution by virtue of the difference that the hydrate and seawater have different densities, so that a hydrate seawater desalination technology can be industrialized. Moreover, hydrate generation and dissociation devices are combined in the same container, and an overturning controllable opening and closing device is utilized, so that the utilization efficiency of a material is improved, and the problem of pore plugging caused by hydrate generation is effectively solved. At the same time of low-temperature seawater spraying, high-concentration seawater is discharged and the seawater is reintroduced into an inner reactor to start a next-step hydrate generation process to implement cyclic production of fresh water by virtue of a hydrate method.

Description

technical field

[0001] The invention belongs to the technical field of hydrate application and relates to an overflow type continuous hydrate method seawater desalination device. Background technique

[0002] With the increasing consumption of fresh water resources around the world, the problem of fresh water has gradually become a serious problem that many countries and regions have to face. Seawater resources are very rich, and seawater desalination is an effective solution. Seawater desalination is more commonly used with low-temperature multiple-effect distillation, multi-stage flash evaporation and membrane reverse osmosis, while hydrate seawater desalination has the technical advantages of low energy consumption, simple equipment, and compactness, and has a good application prospect.

[0003] The principle of seawater desalination by hydrate method is to use the salt-expelling effect of the hydrate formation process. One of the technical characteristics of this method...
