Abstract

The invention discloses a sea water desalination device and a sea water desalination method. The device comprises a water storage tank, wherein the water storage tank is connected with a water inlet pipe; the top of the water storage tank is provided with a steam outlet; a first condenser is arranged in the water storage tank; one end of the first condenser is connected with a compressor which isconnected with an evaporator; a water collection channel is formed below the evaporator; the device is provided with a cavity; the steam outlet is communicated with the cavity; the cavity is providedwith an air inlet which is communicated with the exterior; the evaporator is arranged in the cavity; the cavity is provided with an air outlet on the evaporator; the air outlet is provided with a fan; the cavity is provided with an air return port which is communicated with the air outlet; the output end of the first condenser is connected with a second condenser; the second condenser is communicated with the evaporator; and an expansion valve is arranged between the second condenser and the evaporator. The method comprises a step of simultaneously obtaining fresh water from sea water and air. The sea water desalination device and the sea water desalination method of the invention have the advantages of high fresh water yield, low energy consumption, simple structure and low cost.

Description

technical field [0001] The invention relates to a device and a method for seawater desalination. Background technique [0002] Desalination in the true sense was developed after World War II. After the war, due to international capital's vigorous development of oil in the Middle East, the region's economy developed rapidly and the population increased rapidly. The demand for fresh water resources in this arid region is increasing day by day. The unique geographical location and climatic conditions of the Middle East, coupled with its abundant energy resources, make seawater desalination a realistic choice to solve the shortage of freshwater resources in this region, and put forward large-scale requirements for seawater desalination devices. [0003] So far, seawater desalination methods include freezing, distillation, electrolysis, and reverse osmosis. [0004] Freezing, that is, freezing seawater to freeze it, and separating the salt while liquid fresh water turns into so...
