Abstract

The invention discloses an adsorption type seawater desalination system with higher stability. The desalination system utilizes the situation that seawater is easily evaporated under low pressure andadsorption and desorption performance of a porous medium silica gel on water vapor to realize seawater desalination; and the desalination system comprises six subsystems including a hot-water system,a cooling-water system, a seawater supply device, a fresh-water collecting device, a heat recovery system and a steam system. According to the desalination system provided by the invention, on the basis of a conventional adsorption type seawater desalination principle, the desalination system is additionally provided with heat recovery cycle to reduce energy consumption, and is additionally provided with mass recovery cycle to fully exert adsorption and desorption performance of the silica gel; the desalination system adopts design of separation of evaporation and condensation processes, a gas-liquid mixture is separated through a separation chamber, so that adaptability of the system to change of external conditions is fully improved; and the whole system has no moving parts, and the produced fresh water has better quality and a wide range of applications.

Description

technical field

[0001] The invention relates to the technical field of seawater desalination, in particular to the technical field of adsorption-type seawater desalination. Background technique

[0002] Fresh water is a valuable resource necessary for the economic development of a country's agriculture, industry and various sectors. With the rapid development of society and the rapid growth of population, freshwater resources have presented a serious shortage of supply. Affected by urbanization, economic development and continuous improvement of living standards, the water crisis has become the second largest environmental problem in the world after global warming. At present, the most widely used seawater desalination methods in the world mainly fall into two categories: (1) thermal desalination, such as multi-effect distillation (MED), multi-stage flash (MSF), etc.; (2) membrane desalination, such as positive Osmosis (FO), Reverse Osmosis (RO), etc. Although the optimiz...
