Abstract
A liquid evaporating apparatus includes a liquid inlet 1 to which an evaporator 2 is connected which incorporates a gas inlet 28 and gas flow channels defined by vapor-permeable hydrophobic walls 23, 24, 25, 26. The apparatus may be used to moisturize air in a room, in which case it is configured to circulate room air through the evaporator and to discharge vaporized liquid through the output side 22 of the evaporator and into the room. Alternatively, the apparatus may be used to cleanse liquid, in which case it includes a condensing chamber 3 connected to the output side of the evaporator. The apparatus will also include a closed gas loop 4 which is located between the output side and the input side 21 of the evaporator and which incorporates a fan 5 for transporting a vapor-gas mixture continuously to the condensing chamber.
Claims10
A liquid evaporating apparatus, comprising:
- a) an elongate gas flow chamber (2) having a gas inlet (28) at one end and a gas outlet (22) at another, opposite end,
- b) an elongate liquid chamber disposed within the gas chamber and having a liquid inlet (1) at said one end and a liquid outlet (27) at said opposite end,
- c) the liquid chamber being defined by a plurality of parallel liquid flow channels branching out from the liquid inlet and converging together at the liquid outlet, said flow channels being formed by a vapor-permeable, liquid-restraining material serving as a common diverting wall (23, 24, 25, 26) separating gas in the gas chamber from a liquid in the liquid chamber, wherein the liquid fills the liquid chamber to establish contact with the wall material throughout the liquid chamber, and
- d heating means (63, 64, 65), disposed in the liquid flow channels, for heating said liquid and causing evaporation thereof within the liquid chamber,
- e wherein said vapor-permeable, liquid-restraining material comprises a hydrophobic material such that purified vapors of said liquid pass through the wall material for entrainment by gas flowing through the gas chamber.
