Desalination By Vacuum Distillation

  Vacuum Distillation of Sea Water

Existing technologies can be blended to supply cold & fresh water from saline or brakish water in hot arid regions for drinking and for growing plants in green house. I have designed a concept of VACUUM DISTILLATION for desalination of sea water and it has proved an efficient concept in my small lab facility and now I present here its Design details for the world to try out at large scale facility.

 The design for the plant essentially consist of four cheap compact linear flat mirrored reflectors for Concentraging solar power, a steam generator, a continuously working vacuum pump for reducing pressure, Claude's chamber andd oh! Saline water supply and FREE sunlight. 

The reflectors concentrate sunlight onto the base side of steam generator/boiler where sea water quickly heats up to boiling point at lower than normal boiling temperature ( as pressure inside is kept low by vacuum pump); the vapour is then pumped towards a chamber where it accumulates ( inside insulated walls)  creating high pressure. After achieving certain pressure the vapour moves the heavy lid of the chamber upwards and the vapour travels through pipes (cooled by in-flowing  sea water) towards Claudes chamber. Cold water is obtained at the bottom of claudes chamber (through Joule-Thomson effect) and if the system is to be used for cooling green house too, then, the cold vapour (vapour after it has turned piston) can be fanned-in towards the green house.

Here, the waste heat is maximum utilized by by collecting the waste heat from condensing water vapour and pre-heating the incoming water source, thus making the vapour generation faster and hence the system more efficient. If more useful external work is to be done then the hot vapour from the high pressure chamber can be passed through point X to move the piston and then towards the Claudes Chamber.
