Embodiment Construction

[0029] figure 1 is a cross-sectional view of an exemplary purification system 100 for purifying liquids, such as seawater and / or brackish water, using membrane heating. Because no semi-permeable membrane is required, the exemplary purification system 100 can purify liquids at a lower cost than a reverse osmosis system.

[0030] The purification system 100 may provide efficient heating of the liquid through membrane heating. While existing evaporative systems can use either pool or pool core heating / boiling, the current topic is to utilize film heating that occurs when the temperature difference between the heating element and the boiling point (or saturation temperature) of the liquid is greater than or equal to 93 degrees Celsius. Instead of heating a large volume of liquid, a thin layer of liquid is heated, thereby reducing the energy required to evaporate the liquid. Film heating can achieve evaporation of liquids using less energy than other methods. Furthermore, when ...

Abstract

A purification system can provide for efficient heating of liquid via film heating, which, rather than heating a large volume of liquid, can heat a thin layer of liquid thus reducing the amount of energy required to evaporate the liquid. Film heating can enable evaporation of liquids using less energy than other methods. In addition, when liquids (e.g., seawater) having dissolved solids (e.g., salts) are heated, both the liquid and the solids must be heated. As evaporation occurs, the concentration of solids increases and more energy must be supplied to the liquid in order to cause evaporation. Because purification system can heat only a layer of liquid, less energy is required to heat the solids, which can allow for higher energy efficiencies in purifying liquids. These efficiencies can lead to decreased cost of potable water. Related apparatus, systems, techniques, and articles are also described.

Description

[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 160,664, filed May 13, 2015, under 35 U.S.C. §119(e), the entire contents of which are hereby expressly incorporated by reference. technical field [0003] The subject matter described herein relates to a liquid purification using, for example, hot film heating and evaporation. Background technique [0004] Desalination refers to any of several methods of removing a certain amount of salt and other minerals from brine. Desalination is a form of purification of liquids, especially water. Salt water can be desalinated to produce fresh water suitable for human consumption, irrigation or other uses. Seawater desalination is generally more costly than alternatives (eg fresh water from rivers or underground, water recycling, water conservation, etc.) due to relatively high energy consumption, but alternatives are not always available. [0005] One exemplary method for de...
