Definitions

  • Salt has served as a source for salt for thousands of years.
  • Salt has many uses including flavoring of foods, preservation of foods, etc.
  • Early harvesting of salt from seawater primarily focused on evaporation of the water using solar energy, thereby leaving the salt behind. This requires vast surface areas to provide the required mass of salt.
  • the present invention is directed to a system and method to separate solids from a liquid, such as but not limited to desalinating saltwater, by atomizing the liquid.
  • the resulting liquid droplets having a surface area great enough that the liquid can be rapidly vaporized into a process gas stream traveling through an enclosure. In certain embodiments, the droplets are approximately 20 pm in diameter.
  • the exhaust of the container is connected to a particle separator via ducting.
  • the moist gas exiting the particle separation unit passes through a heat exchanger to drop the gas temperature below the dewpoint. The result is a transition from gas to liquid, after which the resulting liquid (separated from the solids) may be recovered.
  • the system and method allows for a desalination system capable of recovering up to 95% of water from seawater or other saltwater sources.
  • Yet another application of this process in certain embodiments is the removal of microorganisms, e.g., yeast and bacterial from suspension in the aqueous phase.
  • microorganisms e.g., yeast and bacterial
  • Fig. 5 is a diagram illustrating ultrasonic atomization.
  • Fig. 7 is an illustrating of an electrostatic atomizer according to an embodiment of the present invention.
  • FIG. 1 A system and method for implementation of the present invention may be described with reference to Fig. 1.
  • the system is used for desalination of wastewater or seawater, but the invention is not so limited.
  • atomizers 20 use hydraulic or pressure atomization
  • liquid is forced through a small orifice or nozzle 32 at high pressure, resulting in the formation of droplets 34.
  • relatively course droplets are formed, as shown in part (a) of Fig. 2.
  • relatively fine droplets are formed, as shown in part (b) of Fig. 2.
  • the balance of pressures should be such that sufficiently small droplets 34 are formed such that the surface area of the droplets is high enough relative to their liquid volume for liquid/gas separation to take place as described herein.
  • an atomizer 20 of the air (gas-assisted) atomization type may now be described.
  • air or another gas, such as steam, nitrogen, hydrogen, etc.
  • the liquid is atomized by passing it through a nozzle 32.
  • Nozzle 32 has a central bore 34 through which the liquid passes, and one or more outer bores 36 through which the gas passes.
  • the gas is directed by outer bores 36 into the stream of liquid from central bore 34 as the liquid exits central bore 34 The energy from the gas striking the liquid stream breaks up the liquid into droplets.
  • Ultrasonic atomization involves the use of ultrasonic vibrations to break up the liquid into fine droplets 34.
  • an ultrasonic energy source 36 such as a piezoelectric crystal, may create the ultrasonic vibration as a result of a high-frequency input voltage 40.
  • the ultrasonic energy force is sandwiched between a reflecting horn 38 and an atomizing horn 42, the latter of which is connected to nozzle to provide longitudinal vibration to nozzle 32. Liquid arriving at inlet 42 passes through these components to nozzle 32, where the vibration imparted to the liquid results in fine droplets 34.
  • Each atomization system has its own advantages and disadvantages, and the choice of method in different embodiments of the invention depend upon factors such as the desired droplet size, flow rate, viscosity of the liquid, surface tension, and application requirements.
  • range is intended to include all sub-ranges within the range, as well as all individual points within the range.

Abstract

L'invention concerne un système et un procédé pour séparer des solides d'un liquide, tel que le dessalement en vue d'éliminer le sel de l'eau salée, en atomisant le liquide pour créer des gouttelettes de liquide. La surface des gouttelettes est suffisamment grande pour que le liquide puisse être rapidement vaporisé dans un flux d'air de traitement traversant un récipient. Le diamètre des gouttelettes peut être d'environ 20 pm, par exemple. L'évacuation du récipient est raccordée à un séparateur de particules par l'intermédiaire d'un conduit. Le gaz humide sortant de l'unité de séparation de particules passe par un condenseur pour abaisser la température du gaz en dessous du point de rosée. Il en résulte une transition du gaz au liquide, après quoi le liquide exempt de solides obtenu peut être récupéré. En variante, le procédé peut être utilisé pour récupérer un solide désiré à partir d'un liquide.
