Embodiment

[0025] Embodiment: a kind of seawater desalination device (see attached figure 1 attached figure 2 ), including an evaporation chamber 3, a condensation chamber 8 arranged outside the evaporation chamber, the evaporation chamber is connected with a vacuum heat pipe 13, the hot end of the vacuum heat pipe is connected with a heating part, the cold end of the vacuum heat pipe is in the evaporation chamber, and a circulating seawater is arranged in the evaporation chamber Distributor 5. The vacuum heat pipe adopts water gravity vacuum heat pipe. The water gravity vacuum heat pipe is arranged vertically to form a heat pipe bundle. The vacuum heat pipes are separated from each other. The circulating seawater distributor is above the heat pipe bundle, and the seawater is distributed on the surface of the vacuum heat pipe by the circulating seawater distributor. A liquid film is formed, and the liquid film absorbs heat in the process of descending along the heat pipe, forming a thi...

Abstract

The invention relates to a seawater desalination device and method. The seawater desalination device comprises an evaporation chamber and a condensation chamber arranged outside the evaporation chamber, the evaporation chamber is connected to a heating pipe, a hot end of the heating pipe is connected to a heating part, a cold end of the heating pipe is located in the evaporation chamber, and a circulation seawater distributor is arranged in the evaporation chamber. Through high efficiency thermal conduction performances of the heating pipe, seawater is evaporated and then is condensed to form fresh water and superfluous seawater is returned into sea so that water scale is avoided. Through performances of the vacuum heating pipe, seawater desalination energy consumption is reduced.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a seawater desalination device and method using heat pipes for high-efficiency heat conduction. Background technique [0002] Seawater desalination is the use of seawater desalination to produce fresh water. It is an open source incremental technology to realize the utilization of water resources. It can increase the total amount of fresh water without being affected by time, space and climate. The water quality is good and the price is gradually becoming more reasonable. [0003] Since the 1950s, seawater desalination technology has been accelerated with the intensification of the water resource crisis. Among the more than 20 desalination technologies that have been developed, distillation, electrodialysis, and reverse osmosis have all reached industrial scale. levels of production and are widely used throughout the world. [0004] Distillation is a method of boiling seawa...
