Normal-pressure continuous seawater desalting system based on hydrate method and use method of desalting system

Abstract

The invention provides a normal-pressure continuous seawater desalting system based on a hydrate method and a use method of the desalting system. The normal-pressure continuous seawater desalting system comprises a seawater pool, a cooler, a hydrate generating chamber, a heat exchange type decomposer and a steam generator which are sequentially connected. A circulating heat medium system is arranged between the heat exchange type decomposer and the steam generator. A heat exchanger is connected between the seawater pool and the cooler. A cooled seawater input opening, a hydrate output opening,a gasified cyclopentane input opening and a concentrated seawater output opening are formed in the hydrate generating chamber. The cooled seawater input opening is connected with the output end of the cooler. The hydrate output opening is connected with the heat exchange type decomposer. The liquid output end of the heat exchange type decomposer is connected with a fresh water storage tank. The gas output end of the heat exchange type decomposer is connected with the steam generator through a cyclopentane storage tank. The steam generator is connected with the gasified cyclopentane input opening. The concentrated seawater output opening is connected with the cold medium inlet end of the heat exchanger. The normal-pressure continuous seawater desalting system is reasonable in structure, can be repeatedly used, is simple in adjustment and use method and has extremely high practical application value.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to an atmospheric continuous seawater desalination system based on a hydrate method and an application method thereof. Background technique [0002] In recent years, the scarcity of fresh water is gradually becoming a global problem. Many countries have done a lot of research to solve the problem of water resources, among which seawater desalination technology is an effective way to solve this problem, and now mainstream seawater desalination technologies include: low-temperature multi-effect distillation, multi-stage flash evaporation and reverse osmosis. However, these methods have their own shortcomings, such as: low-temperature multi-effect distillation and multi-stage flash evaporation consume a lot of energy and the equipment is easy to foul, and the membrane life of reverse osmosis is short, which leads to high cost. In order to avoid these deficiencies, some new seawate...

Problems solved by technology

At present, in the published patent documents or research results, the efficiency and output of hydrate seawater desalination technology are still limited. More precisely, this technology requires a lot of energy consumption to provide low temperature, high pressure reaction conditions, and hydrate and water desalination.
