Abstract

A water distillation apparatus including a first distillation chamber a condensation chamber and a first storage chamber fluidly connected to each other and able to be isolated from each other using appropriate valves. A second distillation chamber and a second storage chamber are fluidly connected with the condensation chamber and able to be isolated from each other. A vacuum pump is connected to the condensation chamber to induce a vacuum through all of the chambers when they are in an operating state. Water or a solution to be distilled is heated before it enters the first or the second distillation chamber and thus evaporates at a lower temperature than normal due to the induced vacuum, the evaporated water condensing in the condensation chamber and fed to either the first or second storage containers. Multiple distillation and storage containers may be provided to make the process of distillation continuous.

Description

Water distillation apparatus FIELD OF THE INVENTION
[0001] The present invention relates to a water distillation apparatus operating at a pressure less than atmospheric pressure
BACKGROUND
[0002] Clean water, defined as being pure enough for human consumption, is a scarce commodity. The availability of clean water is fundamental human survival and whilst water is in abundance, clean water is not.
[0003] There are many processes to produce clean water from other waters, whether they are saline or waste water. Distillation has long been used to purify liquids, extract solutes, and concentrate substances from solution. Distillation is used in many industries, from oil refineries to alcoholic beverage makers. It is however rarely used for treating water because the cost of distillation exceeds the cost of other forms of treatment.
[0004] The process of distillation is typically performed by adding heat to the solution (water) at atmospheric pressure until the water vaporizes or even evaporates. The generated steam is allowed to condense thus producing fresh water. It is an expensive process since the saline water has to be heated to over 100° C to make the water boil. If the water is placed under vacuum, the boiling point of the water decreases as the pressure decreases.
[0005] It is an object of the present invention to provide a distillation system for producing clean water using a distillation process that overcomes at least some of the current problems or at least provides the public with a useful alternative.
[0006] It is a further object to provide for a distillation process that allows for continuous distillation and condensation. SUMMARY OF THE INVENTION
[0007] In one form of the invention there is proposed a water distillation apparatus including:
a first distillation chamber a condensation chamber and a first storage chamber fluidly connected to each other and able to be isolated from each other;
a second distillation chamber and a second storage chamber fluidly connected with the condensation chamber and able to be isolated from each other;
a vacuum pump operatively connected to the condensation chamber to thereby induce a vacuum through all of the chambers when they are in an fluidly operating state; whereby water entering the first or the second distillation chamber is first heated and evaporates at a lower temperature than normal due to the induced vacuum, the evaporated water condensing in the condensation chamber and fed to a selected one of the first or second storage containers.
[0008] In preference the pipe feeding water to the distillation chambers passes though the condensation chamber first and is subsequently heated.
[0009] In preference there are multiple distillation chambers and storage chambers fluidly connected and able to be isolated form the condensation chamber.
[0010] In preference the apparatus further includes a plurality of sensors associated with each chamber said sensors including but not limited to pressure and temperature sensors.
[0011] In preference the distillation chambers include an outlet valve to remove any water from the chambers.
[0012] In preference the storage chambers include an outlet valve to collect any distilled water from the chambers.

[0017] The following detailed description of a preferred embodiment of the invention refers to the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings and the following description to refer to the same and like parts. As used herein, any usage of terms that suggest an absolute orientation (e.g. "top", "bottom", "front", "back", "horizontal", etc.) are for illustrative convenience and refer to the orientation shown in a particular figure. However, such terms are not to be construed in a limiting sense as it is contemplated that various components may in practice be utilized in orientations that are the same as, or different than those, described or shown. Dimensions of certain parts shown in the drawings may have been modified and/or exaggerated for the purposes of clarity or illustration.
[0018] The solution or water to be distilled is fed through pipe 10 to a first distillation chamber 12a and second distillation chamber 12b. The flow of the solution is controlled by first chamber flow valve 14a and second chamber flow valve 14b. Inlet valve 16 controls the water flowing into pipe 10 in the first instance. Pipe 10 initially passes through a condensation chamber 18 after which it is heated by heater 20 so that the solution that enters the distillation chambers 12 is at a desired temperature. The heating could be sourced from many sources, such as electric, gas or solar.
[0019] A vacuum pump 22 evacuates the air within the condensation chamber
18 and the distillation chambers 12 to significantly less than atmospheric pressure causing the heated solution to evaporate within the distillation chambers 12 at lower temperatures given that the distillation chambers 12 are under a vacuum.
[0020] The evaporated water is fed from the distillation chambers 12 through pipe 24 that feed the evaporated water into the condensation chamber 18 which being at a lower temperatures causes condensation that collects as distilled water at the bottom of the chamber 18. The evaporated water fed into pipe 24 is controlled by valves 26a and 26b. [0021] The collected water 26 is fed though pipe 28 into storage chambers 30a and 30b, that being controlled by valves 32a and 32b. When sufficient water has been collected in the storage chambers 30 valves 32 can be closed and valves 34a and 34b opened emptying the storage chambers 30. The emptying of the storage chambers 30 is assisted by valves 36a and 36b that ensure that the chambers 30 are pressurised
[0022] In operation the reader will appreciate that with multiple distillation and storage chambers the process is made continuous. Thus when distillation chamber 12a needs to be cleaned it is isolated from the system by closing valves 14a and 26a and opening valve 36a draining any remnant fluid. The distillation chamber 12a is also openable via hinge 38 enabling the chamber to be cleaned. Same applies to distillation chamber 12b.
[0023] Whilst two distillation chambers and two storage chambers have been illustrated it is to be understood that there could be a plurality of such chambers ensuring that the distillation process is continuous given that the distillation chamber does not have to be taken off line.
[0024] Various gauges can be employed throughout the system such as temperature gauges 40 and pressure gauges 42 to monitor the operation the system. Of course instead of gauges they could be sensors that feed information onto a control system (not shown). Other sensors that may be employed but are not illustrated may include water level sensors in all of the chambers.
[0025] The process can be adapted to be automatic with periodic maintenance undertaken as required. Multiple vacuum pumps can also be used as well as a cooling system to further decrease the temperature within the condensation chamber.
[0026] Further advantages and improvements may very well be made to the present invention without deviating from its scope. Although the invention has been shown and described in what is conceived to be the most practical and preferred embodiment, it is recognized that departures may be made therefrom within the scope and spirit of the invention, which is not to be limited to the details disclosed herein but is to be accorded the full scope of the claims so as to embrace any and all equivalent devices and apparatus. Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of the common general knowledge in this field.
[0027] In the present specification and claims (if any), the word "comprising" and its derivatives including "comprises" and "comprise" include each of the stated integers but does not exclude the inclusion of one or more further integer.
