Abstract
The present disclosure relates to a method and device for obtaining distillate from non-potable water. The method comprises the steps of utilizing solar power from a solar power system to produce electricity and steam, utilizing the electricity and the steam in a water treatment device to convert the non-potable water into distillate and concentrate, transporting at least a part of the distillate to consumers for use. The method and device provide multiple effect distillation (MED) combined with vapour compression (VC) being able to work 24 hours a day only on solar energy.
Claims19
A method for obtaining distillate from non-potable water comprising the following steps:
- utilizing solar power from a solar power system to produce electricity and heated water,
- converting the heated water into steam,
- utilizing at least the steam in a water treatment device to convert the non-potable water into distillate and concentrate,
- transporting a part of the distillate to consumers for use,
- transporting a second part of the distillate generated in the water treatment device to a first distillate storage tank,
- transporting the second part of the distillate generated in the water treatment device from the first distillate storage tank to the solar power system,
- the solar power system comprises photovoltaic panels to generate electricity from solar power, whereby solar thermal energy is being used to heat the second part of the distillate being transported from the first distillate storage tank along the heated photovoltaic panels, while the photovoltaic panels are being cooled through heat transfer from the photovoltaic panels to the second part of the distillate,
- transporting the heated second part of the distillate from the solar power system to a second distillate storage tank,
- transporting the heated second part of the distillate from the second distillate storage tank to a steam generator for generating steam,
- utilizing the steam in the water treatment device to convert further non-potable water into the distillate and the concentrate.
A device for obtaining distillate from non-potable water comprising:
- a solar power system to produce electricity and heated water from solar power,
- a steam generator for converting the heated water into steam,
- a water treatment device to convert the non-potable water into distillate and concentrate utilizing at least the steam from the steam generator,
- a first distillate storage tank for storing a part of the distillate being generated in the water treatment device, wherein the first distillate storage tank is in fluid connection with the water treatment device and with the solar power system,
- wherein the solar power system comprises photovoltaic panels to generate electricity from solar power and means to guide the part of the distillate along the photovoltaic panels,
- a second distillate storage tank for storing the part of the distillate generated in the water treatment device and heated in the solar power system, wherein the second distillate storage tank is in fluid connection with the solar power system,
- a steam generator for generating steam, wherein the steam generator is in fluid connection with the second distillate storage tank and the water treatment device.
