Description

Brine desalination system

This creation is about a salt water desalination system.

The vast majority of the water on the earth is in the form of seawater, accounting for about 97%. However, seawater is salt water and cannot be used as drinking or irrigation water. In other words, fresh water naturally exists on the surface of the earth, accounting for only 3%. The form of glaciers exists, so the technology of desalinating brine to fresh water available has great application requirements.

The existing desalination technology is mainly divided into two major categories: evaporation method and membrane method. The basic principle of evaporation method is to heat the brine and collect the water mist after evaporation, including multi-effect evaporation method, multi-stage flash method and vapor compression method, but The water mist collected in this way will still have a little salt; the membrane method mainly includes reverse osmosis method and electrodialysis method. The basic principle is to filter the salt water in the semi-permeable membrane so that the salt ions in the brine are semi-permeable membrane. Blocking, through the semi-permeable membrane is fresh water, however, the size of the salt ions is very small, so the thin film method requires the use of a semi-permeable membrane with a very small hole, which is technically difficult and costly.

One of the other purposes of this creation is to propose a brine desalination system.

According to the present invention, a brine desalination system includes a brine atomization device that atomizes the brine at a normal temperature to produce a mixed mist; and a fresh water condensation device that connects The brine atomizing device receives the mixed mist to condense fresh water from the mixed mist.

Wherein, the salt water atomizing device comprises a pressing device and a plurality of spray nozzles, or is realized by a plurality of ultrasonic oscillators.

In one embodiment, the fresh water condensing device includes a fresh water condensing device that condenses the mixed mist at a first temperature and a first pressure to collect fresh water. Preferably, the method further comprises a concentrated brine condensing device, comprising a concentrated brine condensing device coupled to the fresh water condensing device to condense the remaining mixed mist at a second temperature and a second pressure; wherein the first temperature and the first The second pressure is different from the second pressure.
