Definitions

  • This invention relates to a heat exchange element and more specifically, relates to a heat exchange element including a condenser surface having hydrophobic properties and an evaporator surface having hydrophilic properties.
  • the heat exchange element 10 When the conventional heat exchange element 10 is used in a distillation system, the heat exchange element 10 is connected to both an evaporator chamber (not shown) and a condenser chamber (not shown). Typically, the heat exchange element 10 is disposed between these two chambers.
  • water droplets generally indicated at 18
  • a salt water film forms on the evaporator surface 16 as the sea water evaporates into a vapor.
  • the present invention provides a heat exchange element having a water and vapor impermeable substrate.
  • the substrate has a first surface which is typically hydrophobic and an opposing second surface.
  • a composition is disposed on the second surface such that the composition provides an exposed hydrophilic surface.
  • the composition substantially covers the second surface so that the second surface essentially comprises a hydrophilic surface.
  • the first surface serves as a condenser surface of the substrate and the hydrophilic surface and any portion of the second surface not covered by the composition serve as an evaporator surface.
  • One exemplary and preferred use for the heat exchange element of the present invention is in a distillation system for purifying sea water (or brine) to form fresh desalinated water.
  • the use of the hydrophilic composition to define the evaporator surface eliminates the nucleation of vapor bubbles on the evaporator surface and also prevents gas film (or gas blanket) formation on this same surface. As a result, the thermal resistance through the heat exchange element is decreased and the efficiency of the heat exchange element is increased. Furthermore, since the evaporator surface attracts water, little, if any, power is required to recirculate the sea water or brine over the evaporator surface. The need to recirculate the sea water to prevent soft scale formation on the evaporator surface is reduced or eliminated, thereby, further increasing efficiency.
  • FIG. 1 is a cross-sectional side elevational view of a conventional heat exchange element
  • the substrate 102 has a first surface 104 and an opposite second surface 106 .
  • the first surface 104 is intended to act as a condenser surface for producing a condensate.
  • a composition generally indicated at 108 , is disposed on at least a portion of the second surface 106 .
  • the composition 108 is selected so as to impart hydrophilic properties to at least the portion of the second surface 106 where the composition 108 is disposed.
  • An evaporator surface 109 is thus defined by both the hydrophilic composition 108 and the second surface 106 . In the case where the composition 108 entirely covers the second surface 106 , the evaporator surface 109 is defined by the composition 108 .
  • the evaporator surface 109 is defined by the composition 108 and that portion of the second surface 106 which does not have the composition 108 disposed thereon.
  • the composition 108 covers the entire second surface 106 .
  • the entire evaporator surface 109 is a hydrophilic surface.
  • the gas film or blanket 24 which forms on the evaporator surface of the conventional heat exchange element 10 does not form on the evaporator surface 109 of the present invention. Because the gas film 24 is eliminated, greater heat transfer results at the evaporator surface 109 because the liquid to be evaporated may more easily come into contact with the evaporator surface 109 . This also results in an overall increase in the efficiency of the system.
  • the heat exchange element 100 is used in a vacuum vapor compression distillation process, both of the mechanical and thermal types.
  • thermal vapor recompression evaporators the inertia of the steam is used for recycling part of the evaporators through ejectors.
  • mechanical vapor recompression evaporators all of the vapor is recycled back as heating steam using vapor compression with high pressure fans or compressors.
