Definitions

  • the invention relates to distillation apparatus, typically distillation apparatus for water, alcohol, and bio-fuels such as those used for small scale distillation of same, for example, for domestic use in third world environments.
  • Water distillation has been used for decades to purify water Water distillation provides an effective and highly efficient technique for removing bacteria, chemicals, and toxic organic compounds from contaminated water.
  • regular water supplies including "tap" water supplied by a municipality and local or regional well water, often contains dissolved gases, e.g., sulfur dioxide, and/or other contaminants which are harmful to health
  • the water distillation process heats water to produce steam, and then at least partially condenses the steam to form water free from such contaminants.
  • the contaminants having a vaporization temperature higher than that of water remain in the heating unit of the distiller, while solvents which have a boiling point lower than water may be separated from the steam by venting prior to condensation or by so called partial condensation which results in the water being condensed but the solvents remaining in the vapour phase.
  • the invention provides a distillation apparatus for small scale removal of contaminants from a liquid such as water, ethanol, and bio-fuel, said apparatus including a combined heating unit and a condensation unit of the thermo-electric cooler type, which uses the heat of condensation of the vapour being condensed as at least a partial source of energy for the vapourisation of the liquid which is fed to the apparatus so that the boiler zone and condensation zone of the apparatus are adjacent.
  • the thermo-electric cooler may be of the thin film type.
  • thermo-electric cooler may be operated by D. C.
  • thermo-electric cooler may have a coefficient of performance (COP) of up to 2. (with development of thin-film technology the value for COP may increase further)
  • COP coefficient of performance
  • a vortex tube arrangement may be provided at the outlet of the boiler zone so that the vapourised liquid may be separated on the basis of density to at least partially remove contaminants from the vapourised liquid.
  • the vortex tube arrangement may include multiple vortex tubes in series or parallel.
  • the vortex tube separates steam from contaminants and other gasses.
  • the vortex tube separates the ethanol or bio- fuel from steam.
  • Carbon filtration may be used with distillation as follows to pre-filter the fluid prior to distillation.
  • tap or well water may first be sent through a pre-filter to help take out chlorine, odours, sediment, and other organic contaminants before it reaches the boiling tank of the distillation apparatus.
  • the pre-filter is optional as the vortex tube should be able to remove all volatile gases and contaminants suspended in the vapourised liquid, for example steam.
  • the steam After the steam is condensed into distilled water it may be passed through a carbon post filter to remove any gases or volatile organic contaminants (VOCS) that might have escaped during the boiling process.
  • VOCS volatile organic contaminants
  • the post filter is optional whereas not using a post filter in the past with distillation might have produced an off taste in distilled water, due to these VOCS.
  • Waste heat may also be recovered by a heat exchanger arrangement that transfers heat from the condensed liquid to the feed liquid thus pre-heating the feed liquid before it goes to the boiler chamber
  • Waste heat from the outlet of the vortex tube may also be recovered and the heat transferred to the feed liquid through heat exchange.
  • a piezo ultrasonic cleaning system may be embedded in the boiler chamber
  • the piezo ultrasonic cleaning system may be portable and/or removable.
  • a heat sink may be located within the boiler chamber and/or the condensing chamber.
  • Figs 1 a and 1 b show a schematic representation of a distillation apparatus of the invention
  • Figs 2 a and b show a vortex tube arrangement of the apparatus of Figure 1 ;
  • Fig 3 shows a representation of the Peltier effect
  • Fig 4 shows the reduction in size of Thermo-electric cooling (TEC) devices.
  • the vortex tube shown in the Figures 2 below removes all contaminants and volatile gases because of the centrifugal rotation of the steam and adjustable cone valve.
  • the volatile gases and low temperature boiling gases have densities higher than steam. The low temperature gases will therefore first boil off.
  • An optional filter on the hot side of the vortex tube is included to absorb all potentially poisonous gases
  • the distillation apparatus could be used to distil alcohol (ethanol) or bio fuel. Distillation is the separation of a liquid from other liquids or solids. Because each substance has a fixed rate of vaporization (which varies with heat) - determined by the pressure the vapours develop in a closed container to achieve equilibrium with the fluid - one liquid can be separated from other matter by carefully controlling the heat applied to the mixture. Alcohol's vapour pressure happens to be higher than water's, so ethanol's vapour pressure reaches an equilibrium with atmospheric pressure (the point at which a liquid boils) before water's vapour pressure does.
  • the vapours given off by boiling a combination of the two will have a disproportionately large share of alcohol For example, in a mash that has 10% alcohol and 90% water, the vapours released will be about 80% alcohol. To increase that percentage (and raise the proof), the vapours must be condensed and re- vapou ⁇ sed Each re-distillation raises the proof of the batch further until the liquid reaches an azeotropic condition at 95.57%. The process of enrichment (or rectification) is halted by the balance (azeotropy) of alcohol and water in the vapours.
  • Ethanol vapour has a density of 2.04 kg/m 3 at 78 deg C compared to steam which has a density of 0.6 kg/m 3 at 100 deg C
  • the vortex tube's cone can therefore be adjusted (opening increased) to allow for example 90 % hot side output (5-10% in the case of water distillation).
  • the higher density ethanol vapour will therefore exit at the hot side of the vortex (waste side for the water distillation process) and the water steam/vapour at the cold side of the vortex tube
  • Figure 1 a and 1 b shows a water distillation apparatus in which the various reference numerals have the meanings as indicated below:
  • 1 - 2 shows the water inlet to feed water pre-heat chamber I: manually pour water into chamber or connect to water supply with valve.
  • a water level measuring system for example a capacitance probe, can be used when chamber I is connected to pressurised water supply to control the inlet valve thereby controlling the level of water in chamber I.
  • a pre-filter may be added to remove to help take out chlorine, odours, sediment, and other organic contaminants before it reaches the boiling tank of the distiller
  • solenoid valve or any other applicable valve
  • the solenoid valve allows air to escape from chamber Il to chamber I to atmosphere through a breather valve in chamber I during the filling process.
  • cone valve regulated to remove contaminants, expected steam/water waste of 5 to 20 % as a result of outer vortex generated flow in tube.
  • Filter may be used on vortex hot side output to absorb contaminants and volatile gases.
  • Cone valve opening may be controlled actively during distillation
  • thermoelectric cooler TEC
  • One directional breather pressure relief valve ensures that pressure inside chamber III does not increase above atmospheric pressure. Excess air in chamber is expelled once condensed water volume increases.
  • the condensed temperature is approximately 50- 60 deg C (1 1 1 -50-vortex effect).
  • a temperature and pressure sensor is imbedded in the TEC unit (on the hot side) or in the boiler chamber housing to control temperature and pressure actively and to prevent dry boiling.
  • the water temperature rises to a temperature above 100 0 C, killing bacteria, cysts, and viruses that may be present.
  • the pressure of the pressure relief valve can be adjusted to vary the pressure inside the boiling chamber thereby increasing the velocity of the outlet steam. Higher velocity will increase the efficiency of the vortex tube shown in Figures 2.
  • Figures 2 and b show the basic operation of the Ranque-Hilsch standard vortex tube or counter-flow vortex tube when used with compressed air
  • Compressed air normally up to 6 9 bar, is ejected tangentially through a generator into the vortex spin chamber. At up to 1 ,000,000 RPM, this air stream revolves toward the hot end where some escapes through the control valve. The remaining air, still spinning, is forced back through the center of this outer vortex. The inner stream gives off kinetic energy in the form of heat to the outer stream and exits the vortex tube as cold air. The outer stream exits the opposite end as hot air.
  • the vortex tube can operate with steam as well as used in this specific application. Experimental tests will however have to be conducted to quantify the efficiency of the vortex tube when steam is used.
  • Distillation apparatus can be operated by manually filling the boiler chamber or by connecting the input to a water supply (municipal water or reservoir tank)
  • the boiler chamber can be cleaned with warm tap water to remove any loose residue. As scale deposits build up inside, an approved cleaner, such as KLEENWISETM, can also be used to remove deposits. White vinegar or automatic coffee pot cleaner can also be used. Use a soft plastic or nylon scouring pad if needed. Do not use abrasive cleaners, caustic acids, steel wool pads or metal utensils. Rinse thoroughly after cleaning.

  • Another version of the distillation apparatus can use a built in piezo ultrasonic cleaning system to remove deposits from boiler chamber and copper heat sink.
  • This may include an automated cleaning system with an embed ultrasonic cleaner and circulation system where water is pump into the boiler chamber, the piezo ultrasonic cleaner is activated and the water is circulated through the boiler chamber with and external filter that filters out the loose residue
  • the apparatus may have a system built in that monitors the time it takes per distillation cycle. As deposits increase in the boiler chamber the heat transfer coefficient between the TEC and water will decrease and the time per cycle will increase. The controller can then be programmed to shut the apparatus down and start a cleaning cycle once the cycle time increases to a set limit
  • the heat transfer is based on thermoelectric modules.
  • thermoelectric modules The latest technology on thermoelectric modules is Thin-Film eTECTM Technology. Available now from NextremeTM and Nano CoolerTM.
  • Thermoelectric coolers operate using the Peltier effect as shown in Figure 3 When an electric current is driven through a circuit containing two dissimilar materials, heat is absorbed at one junction (the cold side) and released at the other junction (the hot side). This Peltier effect is particularly strong when one material is an n-type semiconductor and the other a p- type semiconductor.
  • this P/N junction is fabricated with materials that have high electrical conductivity and poor thermal conductivity to maximize current flow and minimize heat flowing back from the hot side to the cold side. Since heat naturally flows down a temperature gradient from hot to cold, a TECs ability to move heat from cold to hot in a solid-state fashion is unique. By reversing the polarity of the applied DC current, heating is also possible. This property is especially useful for applications requiring both cooling and heating for precise temperature control.
  • Figure 3 illustrates the Peltir effect in which TECs have traditionally been fabricated using bulk material processing techniques.
  • Thermoelectric pellets with typical dimensions in X and Y of 1 mm x1 mm and 1 mm thickness are assembled into a large array of elements between two ceramic substrates.
  • State-of-the art bulk thermoelectrics can be made with pellets as thin as 200 microns.
  • these bulk TECs are relatively thick and bulky, have low heat flux, slow response, low efficiency, poor reliability, and require low voltages / high currents.
  • NextremeTM uses semiconductor processing techniques to create a nano- structured thin-film used for the P and N legs.
  • Nextreme'sTM thermoelectric thin-film is typically 5 to 10 microns thick versus 200 microns for the thinnest pellets used in bulk TECs, resulting in several benefits
  • thermoelectric material which is inversely proportional to the thickness of the thermoelectric material is 20+ times greater than bulk TECs.
  • Nextreme'sTM eTECs TM pump a maximum heat flux of 200 - 400 W/cm 2 versus less than 10 W/cm 2 for typical bulk TECs •
  • Nextreme's eTECsTM can operate in a high COP (Coefficient of Performance) regime and still pump a reasonably high heat flux (50 - 100 W/cm 2 ).
  • COP is a measure of efficiency defined as cooling power divided by input power.
  • Nextreme's eTECTM adds just 100 microns of height to a heat spreader, enabling unobtrusive integration close to the heat source.
  • NextremeTM uses semiconductor processing techniques to create a nano- structured thin-film used for the P and N elements.
  • thermoelectric thin-film is typically 2Ox thinner than the thinnest pellets used in bulk TECs, resulting in several benefits.
  • Heat flux which is inversely proportional to the thickness of the thermoelectric material, is 20+ times greater than bulk TECs.
  • Nextreme's eTECsTM can operate in a high COP (Coefficient of Performance) regime while still pumping a high heat flux.
  • COP is a measure of efficiency defined as cooling power divided by input power. The input power can be dynamically controlled to provide active cooling.
  • Nextreme's eTECTM has a very fast, millisecond response time for rapid cooling and heating to maintain a precise temperature.
  • Nextreme's eTEC is very thin, enabling unobtrusive integration close to the heat source.
  • Optional piezo ultrasonic cleaning system imbedded in boiler chamber- or portable/removable It works as follows: a surfactant chemical is added which breaks down the surface tension of the water base. An ultrasound generating transducer is built into the chamber, or may be lowered into the fluid. It is electronically activated to produce ultrasonic waves in the fluid. The main mechanism of cleaning action is by energy released from the creation and collapse of microscopic cavitation bubbles, which break up and lift off dirt and contaminants from the surface to be cleaned. The higher the frequency, the smaller the nodes between the cavitation points which allows for more precise cleaning.
  • the bubbles created can be as hot as 10,000 degrees and 50,000 lbs per square inch, but are so small that cleaning and removal of dirt is the main result • Imbedded temperature and pressure sensor in TEC or boiler chamber housing to enable active temperature and distiller control using a dedicated controller printed circuit board.
  • thermoelectric element to boil water- for example an element with Coefficient of Performance of 2 (COP) can generate 400 watt cooling with an input of 200 watt electrical and generates 600 watt of heat COP is a measure of efficiency defined as cooling power divided by input power.
  • the TEC distiller will therefore use up to 3 x less electricity compared to heater element distillers that do not recover the waste heat.
  • Ketron PEEK 1000 is one viable option with an operating temperature up to 523 K and conductivity less than 0 4 Watt/mK option. Any suitable material can be used.
  • Distillation apparatus housing can be mass produced at low cost • Low DC voltage required up to 48 V
  • This distiller should be able to operate with efficiencies up to 95 % in terms of distilling water (for example for 5% water waste, gases and contaminants would be included)
  • Thermoelectric thin-film elements can also be used to generate electricity from heat (sun and any source of heat). Nextreme's eTEG is optimized to provide power for high heat fluxes (>20 W/cm 2 ) with a very small form factor. Power can therefore be generated in harsh, remote environments using thermoelectric thin-film elements to power the distiller.
  • Thin-film TEC units can be massed produced. • Thin-film TEC units high heat flux resulting in compact heat transfer element.
  • distillation apparatus size and capacity is adjustable and large units are feasible and only depend on TEC development in terms of maximum pumping power.
  • Existing units have pumping powers up to 200 watt.
  • the current sizes of the TEC units are dependant on the market and current applications.
