Abstract

The invention discloses a solar seawater desalination device. The device comprises an oscillatory flow heat pipe air heat collector, an evaporator and a condenser, wherein the oscillatory flow heat pipe air heat collector is provided with a steam outlet and a steam inlet; the evaporator is provided with an air outlet and a seawater outlet; a gas distributor is arranged at the bottom of the evaporator; the condenser is provided with a wet air inlet, a steam outlet and a freshwater discharge outlet; a condensing coil is arranged in the condenser; one end of the condensing coil is connected with a seawater pump and the other end thereof is led into the evaporator; the steam outlet of the oscillatory flow heat pipe air heat collector is connected with the gas distributor; the air outlet of the evaporator is connected with the wet air inlet of the condenser; and the steam outlet of the condenser is connected with the steam inlet of the solar air heat collector. The device has the following advantages: the device reduces corrosion to the heat collector and improves the heat collection efficiency of the heat collector; the seawater temperature is low during operation, so the whole device does not have obvious scales; and the device has simple structure and small volume, can operate under normal pressure and has broad market prospects.

Description

technical field [0001] The invention relates to the field of seawater desalination, in particular to a solar seawater desalination device. Background technique [0002] Fresh water is one of the basic materials for the survival and development of human society. But in fact, the fresh water that humans can draw from rivers and lakes only accounts for 0.014% of the total water. With population growth and rapid economic development, human demand for fresh water continues to grow. In order to cope with global water shortages, desalination of seawater and brackish water has become an effective way for countries around the world to solve water problems. [0003] The use of solar energy to achieve seawater desalination has the advantages of not consuming conventional energy, not producing secondary pollution, and saving operating costs. The humidification and dehumidification seawater desalination method using flowing air as the water vapor carrier has the advantages of flexible ...
