The apparatus described herein uses a disc wafer-type rotor featuring channels disposed around its circumference and around the interior circumference of the rotor housing specifically to induce cavitation. The channels are shaped to control the size, oscillation, composition, duration, and implosion of the cavitation bubbles. The rotor is attached to a shaft which is driven by external power means. Fluid pumped into the device is subjected to the relative motion between the rotor and the device housing, and exits the device at increased temperature. The device is thermodynamically highly efficient, despite the structural and mechanical simplicity of the apparatus. Such devices accordingly provide efficient, simple, inexpensive, and reliable sources of distilled potable water for residential, commercial, and industrial use, as well as the separation and evaporation of other liquids.

An evaporator according to an exemplary embodiment includes: a column in which a plurality of packings are stacked; an upper inlet, a middle inlet, and a lower inlet provided in an upper portion, a middle portion, and a lower portion of the column, respectively; an upper outlet and a lower outlet provided in the upper portion and the lower portion of the column, respectively; a pump connected to the lower outlet; and a heater connected between the pump and the middle inlet.

An apparatus for generating purified liquid from an input liquid, comprises, an evaporation chamber flooded with the input liquid and wherein the evaporation chamber generates saturated gases and comprises a shared wall with the condensation chamber and wherein the evaporation chamber is configured to generate evaporation cavities and condensation cavities on respective sides of the shared wall for a 2-phase counter flow of a liquid phase component and a gaseous phase component in composite flows for a 2-phase to 2-phase direct latent heat exchange. A condensation chamber has channels disposed in the input liquid, wherein liquid-saturated gases are generated therefrom in the evaporation chamber. The apparatus is operated as a four-port counter-flow heat exchanger where two different fluids are exchanging heat based on the inlet ports of both fluids being on opposite sides and the outlet ports of both fluids are also on opposite sides of the evaporator and condenser.

The vaporizer assembly includes a nail sub-assembly formed of a high rate of heat transfer material and an adapter assembly formed of a lower rate of heat transfer material. The nail sub-assembly includes a bowl at an upper end and a shaft extending down from the bowl. The shaft has a hollow bore passing therethrough. The nail sub-assembly is preferably formed of a titanium alloy which can be heated to high temperatures without damage thereto. The adapter has a hollow core sized to receive the shaft of the nail therein. The nail is preferably threaded along with portions of the adapter to facilitate height adjustability of the nail relative to the adapter. Lower portions of the adapter are configured to mate with a water pipe inlet tube or other downstream vapor handling device.

A gas capture system includes a first heat exchanger that exchanges heat between cold heat of a fuel that is vaporizing and a first gas mixture to cool the first gas mixture, a first dehumidifier that dehumidifies the first gas mixture cooled through the first heat exchanger, a first compressor that presses the first gas mixture passing through the first dehumidifier, a first separation device that separates a second gas mixture including a reference gas from the pressed first gas mixture, and a liquefier that liquefies the reference gas to generate a reference liquid.

Systems and methods for the removal of scale in humidification-dehumidification desalination apparatuses are generally described.

Various techniques are described for enhanced combustion of hot water extraction (HWE) derived liquor. For example, the HWE derived liquor can be pre-treated prior to introduction into a combustion chamber. The pre-treatment can include subjecting HWE derived liquor to filtration to remove suspended solids, evaporation to produce a first stage concentrated HWE liquor; additional concentration to produce a second stage concentrated HWE liquor; additional filtration to remove additional suspended solids; and pre-heating to produce a preheated HWE liquor. The preheated HWE liquor can be atomized and combined with pre-heated combustion air supplied into a combustion chamber to effect combustion of the HWE derived liquor.
