An atmospheric continuous seawater desalination system based on hydrate method and its application method

Abstract

An atmospheric continuous seawater desalination system based on the hydrate method and its use method, including seawater pools, coolers, hydrate generation chambers, heat exchange decomposers and steam generators connected in sequence, heat exchange decomposers and steam generators There is a circulating heat medium system between the generators; a heat exchanger is connected between the seawater pool and the cooler; the hydrate generation chamber is equipped with a cooling seawater input port, a hydrate output port, a vaporized cyclopentane input port and a concentration The seawater output port; the cooling seawater input port is connected to the output end of the cooler; the hydrate output port is connected to the heat exchange decomposer, the liquid output end of the heat exchange decomposer is connected to a fresh water storage tank, and the gas output end is passed through cyclopentane The gas storage tank is connected with the steam generator, and the steam generator is connected with the gasification cyclopentane input port; the concentrated seawater output port is connected with the refrigerant inlet port of the heat exchanger. The invention has reasonable structure, can be used repeatedly, has simple debugging and using methods, and has great 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.
