Embodiment 1

[0023] Such as figure 1 As shown, the nanofluid seawater desalination system using air as the heat transfer medium consists of an air compressor 1, an air splitter 2, a vortex tube 3, a first-effect seawater distiller 4, a second-effect seawater distiller 5, and a first preheater 6. The second preheater 7, the third preheater 8, the first condenser 9, the vacuum pump 10, the second condenser 11, the fresh water pump 12, the sea water pump 13, the ultrasonic mixer 14, the sea water pool 15, the booster Composed of pump 16, nanofluid splitter 17, concentrated seawater pump 18 and other components

[0024] The compressed air outlet of the air compressor 1 is connected to the inlet of the air splitter 2. The air splitter 2 has multiple outlets, and each outlet is connected to a nozzle of a vortex tube 3. Here, the air splitter 2 has four outlets. , the vortex tube 3 is also four. The structure of the vortex tube 3 is prior art, including a nozzle, a vortex generating chamber, a ...

Abstract

The invention discloses a nanofluid seawater desalination system using air as a heat transfer medium; air enters vortex pipes through an air compressor and an air diverter; hot end outlets of the vortex pipes are connected with a first effect seawater distiller; cold air enters a second condenser; seawater and nanoparticles are mixed in a seawater pool, and then the mixture enters a nanofluid diverter and is divided into a first condenser, a second preheater and a third preheater. Nanofluid outlets of all the preheaters are connected with a nanofluid inlet of the first effect seawater distiller. Hot air coming out of the first effect seawater distiller is used as a heat source of the third preheater; water steam of a former effect seawater distiller is used as a heat source of a next effect seawater distiller; a thick nanofluid of the former effect seawater distiller flows to the next effect seawater distiller; a thick nanofluid and water steam coming out of the final effect seawater distiller are respectively used as a heat source of the second preheater and a heat source of a first preheater; water steam and fresh water are condensed through the first condenser and the second condenser; and high efficiency and energy saving are achieved.

Description

technical field [0001] The invention relates to a seawater desalination system, in particular to a nanofluid seawater desalination system using air as a heat transfer medium. Background technique [0002] The survival of human beings needs fresh water, and the development of human beings needs a lot of fresh water. However, the content of fresh water resources on the earth is less than 3%, and most of them are difficult to be used. With the rapid development of industry, the consumption of energy and fresh water resources is getting faster and faster, and the problem of fresh water shortage has appeared to varying degrees in most parts of the world. Population growth will exacerbate the current shortage of fresh water. Studies have shown that seawater desalination is an effective way to solve the shortage of freshwater resources. [0003] Seawater desalination technology is a technology for separating salt and water. There are currently more than ten methods, the most impo...
