Description
- This Application incorporates and claims the benefit of U.S. Provisional Application No. 60/254,585, filed Dec. 12, 2000, by Freeman Wilks, entitledMethod and Apparatus for Providing Both Heated and Distilled Water.
- The present invention is directed to a method and device for heating water, e.g., for household use, and for concurrently providing distilled water, e.g., for drinking (a thermostil). In the device, the energy used to distill water is then used to heat water in, say, a water heater, thus providing a very economical technique for obtaining clean drinking water. Currently, the cost of distilled water for drinking purposes or other forms of human consumption is uneconomical.
- Some techniques or apparatuses have been proposed for economical drinking water distillation. One apparatus includes a water heater and distiller apparatus in which condensing steam in the distilling portion of the apparatus gives up its latent heat to water which is being heated in the water heating portion of the apparatus. However, the devices promote the use of separate or auxiliary heating elements and controlling energizing thereof based on an amount of fluid in a boiler, rather than exploiting the constant source of energy provided by a pilot light and controlling the amount of fluid to be evaporated thereby according to the amount of fluid in the boiler or amount of fluid recovered in a distillate tank. See, for example, U.S. Pat. No. 4,690,102, issued Sep. 1, 1987, to G. Sundquist, forWater Heater and Distiller Apparatus and U.S. Pat. No. 5,304,286, issued Apr. 19, 1994, to D. G. Palmer, entitled Water Supply System.
- Another device includes a feed water intake which provides water in excess of the distilled water output, a heater controlling the quantity of water boiled, a waste water exit port to remove accumulated water above a certain level, a distilled water exit port in the vapor space, a condensing device to transfer the heat of condensation to a hot water tank and a waste water heat exchange device to transfer heat from a waste water to the hot water tank. See, for example, U.S. Pat. No. 4,601,789, issued Jul. 22, 1986, to J. G. Bjorklund entitledWater Purification Apparatus.
- What are needed, and not taught or suggested in the art, are an apparatus for and a method of heating fluid with a gas heater and distilling fluid with the pilot light of the gas heater, and an apparatus for heating fluid with a gas heater and distilling fluid with an electric filament.
- The invention provides a method and an apparatus for heating fluid with a gas heater and distilling fluid with the pilot light of the gas heater. The apparatus for heating fluid and distilling fluid includes a main tank for containing fluid to be heated, a heater, adapted to have a pilot light, for heating the fluid in said main tank and an evaporator tank for vaporizing fluid received therein with heat from the pilot light. The method of heating fluid and distilling fluid includes heating a first volume of fluid with a heater having a pilot light and heating a second volume of fluid with the pilot light.
- The invention provides improved elements and arrangements thereof, for the purposes described, which are inexpensive, dependable and effective in accomplishing intended purposes of the invention. Other features and advantages of the present invention will become apparent from the following description of the preferred embodiments which refers to the accompanying drawing.
- The invention is described in detail below with reference to the following figures, throughout which similar reference characters denote corresponding features consistently throughout, wherein:
- FIG. 1 is a schematic view of an embodiment according to principles of the invention; and
- FIG. 2 is a schematic view of another embodiment according to principles of the invention.
- The invention is a method and an apparatus for providing heated and distilled fluid. Referring to FIG. 1, the apparatus includes a
condensing tank 100, for receiving fluid and condensing an evaporated fluid therewith, amain tank 200, for receiving and heating condensing fluid fromcondensing tank 100, aheater 300, having apilot light 305, for heating fluid inmain tank 200, anevaporator 400, for vaporizing fluid received therein with heat frompilot light 305, aholding tank 500, for supplying fluid toevaporator 400, a delayingfloat bowl tank 600, for regulating fluid flow fromholding tank 500 toevaporator 400, and adistillate tank 700, for receiving condensate from the vaporized fluid. -
Condensing tank 100 receives fluid from amain supply 105 at aninlet 110. Fluid frominlet 105 passes up throughcondensing tank 100, across acondensing coil 115 disposed therein, and passes out ofcondensing tank 100 viaoutlet 120.Condensing coil 115 exchanges heat between vaporized fluid passing throughcondensing coil 115 and fluid received incondensing tank 100, as described below. - According to natural physical law, heated portions of the fluid in condensing
tank 100 rise relative to cooler portions thereof. Accordingly,outlet 120 is vertically superior to inlet 110 to exploit this natural physical law and pass heated fluid from condensingtank 100 tomain tank 200, thereby conserving energy by reducing the amount of heat needed to heat fluid inmain tank 200. -
Main tank 200 receives fluid from condensingtank 100 via inlet 205. Heated fluid is drawn frommain tank 200 for ordinary home usage viaoutlet 210. Similar tocondensing tank 100,outlet 210 is vertically superior to inlet 205 so that the hottest fluid is drawn frommain tank 200. -
Heater 300 is arranged relative tomain tank 200 to heat fluid therein in a conventional manner.Heater 300 may be fueled by any energy source, such as oil, gas or solid fuel, so long asheater 300 has apilot light 305 for igniting same for intermittent, controlled burning and heating of the fluid. In this embodiment, a heater having an electronic starter or igniting element may not be substituted forheater 300 because the invention exploits heat thrown bypilot light 305, as discussed below. An alternative embodiment, discussed below, substitutes an electric element forpilot light 305. -
Holding tank 500 receives fluid frommain supply 105 at aninlet 505. Fluid passes fromholding tank 500 viaoutlet 510. Afloat switch 515 monitors or corresponds to and regulates the amount of fluid received inholding tank 500. When thefluid level 520 inholding tank 500 falls below a predetermined level,float switch 515 influences a valve (not shown) to open, permitting fluid frommain supply 105 to enterholding tank 500. Whenfluid level 520 reaches or exceeds the predetermined level,float switch 515 influences the valve (not shown) to close, prohibiting fluid frommain supply 105 from enteringholding tank 500. - A valve525 regulates fluid communication between
main supply 105 andholding tank 500. Valve 525 may prohibit flow to holdingtank 500, for example, to enable installation, maintenance, repair, replacement, etc. thereof or other downstream structures. - Delaying
float bowl tank 600 receives fluid fromholding tank 500 viainlet 605. Fluid passes from delayingfloat bowl tank 600 via outlet 610. Afloat 615 monitors or corresponds to thelevel 620 of fluid in delayingfloat bowl tank 600. Float 615 influences a first fluid flow regulator 625 which regulates fluid flow into delayingfloat bowl tank 600. First fluid flow regulator 625 effectively limits the fluid level 415 inevaporator 400 according to thefluid level 620 in delayingfloat bowl tank 600. - An embodiment of first fluid flow regulator625 includes a
lever 630 connected to or responsive to a position offloat 615. Lever 630 may have a first arm 640 that pivots about pivot point 635. A second arm 645 extending from pivot point 635 may be connected to astopper 650 or influence the operation of a valve (not shown). In operation, whenfloat 615 urges lever 630 to pivot, lever 630 urges stopper 650 from or intooutlet 510 ofholding tank 500, thereby respectively permitting or prohibiting flow into delayingfloat bowl tank 600. -
Evaporator 400 receives fluid from delayingfloat bowl tank 600 via inlet 405. Fluid passes fromevaporator 400 viaoutlet 410. Fluid level 415 inevaporator 400 corresponds tolevel 620 in delayingfloat bowl tank 600. -
Pilot light 305 is arranged relative toevaporator 400 to heat fluid therein in a conventional manner. As is conventional to many gas applications,pilot light 305 burns continuously, barring interrupted gas service, malfunction or other unanticipated phenomena. Consequently,pilot light 305 provides a continuous source of heat for heating fluid inevaporator 400, which otherwise goes untapped. - Fluid in
evaporator 400 is continuously heated bypilot light 305 such that some of fluid evaporates. The vaporous evaporated fluid passes fromevaporator 400, viaoutlet 410, intoconduit 420. Preferably,conduit 420 is insulated. Vaporized fluid fromconduit 420 passes into condensingcoil 115. - As is well known, the process of heating a liquid until the liquid transforms into a gaseous state and/or heating a gas increases pressure. Accordingly, as is common to boilers of many applications, to prevent dangers that could arise due to unregulated pressure buildup,
evaporator 400 has a valve 425 to prevent pressurization withinevaporator 400 above a predetermined pressure. - When
evaporator 400 is not in service, to prevent vapor lock and/or dangerous accumulation of undesirable gases,evaporator 400 has a vent 430 which is opened to ventevaporator 400. Vent 430 is closed whenevaporator 400 is in service to avoid wasteful escape of vaporized fluid. - As mentioned above, vaporized fluid passing through condensing
coil 115 exchanges or transfers the latent heat of condensation to, thereby heating, fluid received in condensingtank 100. Fluid condensed incoil 115, under the influence of gravity, passes todistillate tank 700. -
Distillate tank 700 receives fluid from condensingcoil 115 through aninlet 705. Distilled fluid is drawn fromdistillate tank 700 via an outlet which may feed a tap (not shown). Afloat 715 monitors or corresponds to thelevel 720 of fluid indistillate tank 700.Float 715 influences a secondfluid flow regulator 725, which influences first fluid flow regulator 625, which in turn regulates fluid flow into delayingfloat bowl tank 600, as described above. As a safeguard, an overflow outlet 710 draws fluid fromdistillate tank 700 to holdingtank 600 when thelevel 715 of fluid indistillate tank 700 rises to or beyond a predetermined level. Secondfluid flow regulator 725 effectively limits fluid level 415 inevaporator 400 according to thefluid level 715 indistillate tank 700. - An embodiment of second
fluid flow regulator 725 includes a lever 730 connected to or responsive to a position offloat 715. Lever 730 may have afirst arm 740 that pivots about pivot point 735. A second arm 745 extending from pivot point 735 may have an extension 750 received in a cup 655 or other structure that may be influenced by arm 745 or extension 750. In operation, whenfloat 715 urges lever 730 to pivot, lever 730 urges first fluid flow regulator 625 to urgestopper 650 intooutlet 510 of holdingtank 500, thereby prohibiting flow into delayingfloat bowl tank 600, or allows first fluid flow regulator 625 to operate unencumbered. - A
valve 755 regulates fluid communication between condensingcoil 115 anddistillate tank 700.Valve 755 may prohibit flow todistillate tank 700, for example, to enable installation, maintenance, repair, replacement, etc. thereof or other downstream structures. - FIG. 2 shows an alternative embodiment of the invention. Rather than
pilot light 305, as shown in FIG. 1, this embodiment employs anelectric filament 800 disposed, as a heat source for heating fluid, inevaporator 400.Electric filament 800 provides about the same power aspilot light 305. - Rather than being a constant heat source,
electric filament 800 is energized when the fluid level indistillate tank 700 reaches a predetermined level. To this end, for example, when fluid indistillate tank 700 attains thelevel 720,flow regulator 725 causes switch 805 to close, thereby energizing asolenoid 830, which closes acircuit 835 for energizingelectric filament 800. - More specifically, fluid level in
distillate tank 700 influences flowregulator 725, as described above.First arm 740 of lever 730 offlow regulator 725 drives apin 810 against afirst contact 815 to overcome a bias with respect to, for making contact with a second contact 820. Aspring 825 may be interposed betweenpin 810 andfirst contact 815. - When
switch 805 is closed, energy from a direct current source 837 is directed to contactsolenoid 830.Solenoid 830 drives a third contact 840 to overcome a bias with respect to, for making contact with afourth contact 845, thereby closingcircuit 835. - Although the invention has been described in relation to particular embodiments thereof, many other variations and modifications and other uses will become apparent to those skilled in the art. The invention is not limited by the specific disclosure herein, but only by the appended claims.
