Description
- This patent application is a divisional application of U.S. patent application Ser. No. 13/735,950, entitled “Methods and Apparatus for Reclaiming Heat during Liquid Purification using Heat Exchanges.” filed on Jan. 7, 2013 which is a continuous-in-part (CIP) application of co-pending U.S. patent application Ser. No. 13/214,114, entitled “METHODS AND APPARATUS FOR PURIFYING LIQUID USING REGENERATING HEAT EXCHANGE,” which has been issued into a U.S. Pat. No. 9,211,482, filed on Aug. 19, 2011, the disclosure of which is incorporated herein by reference.
- The exemplary embodiment(s) of the present invention relates to heat purification process. More specifically, the exemplary embodiment(s) of the present invention relates to heat recovery process.
- Clean water is critical to all life forms including humans or animal on this planet. With enhanced technology and information technology in recent years, demand of consumable drinking water or high quality drinkable water is steadily increasing across the globe. For example, readily available clean drinkable water can reduce disease, epidemic, poverty, and/or conflict throughout the world. With increasing world population and finite amount of clean water, demand of high quality clean water will continue in the future.
- The standards for drinking water are typically set by governments, local authorities, or industry associations, and such standards typically set limits of maximum amount of contaminants that could have in the water but still safe for human consumption. To provide clean water, various water purification techniques have been developed over the years. For example, conventional purification systems include carbon filtration, membrane filtration, chlorination, ion exchange, oxidation, and/or reverse osmosis. A drawback associated with such techniques is that conventional purification techniques may require numerous treatment steps in order to be able to remove contaminants, such as living organisms, bacteria, viruses, arsenic, lead, and mercury.
- A typical approach to solve the conventional purification system is to use vapor distillation process to purify water. A problem associated with a typical water distiller is that they are large, costly, and inefficient. For example, a conventional water distiller consumes large amount of energy such as electricity to produce small amount clean or distilled water. Another problem associated with a typical household or laboratory water distiller is that it takes hours to produce one gallon of clean water. Another drawback associated with a conventional temperature based purification system is heat loss during the process of liquid purification.
- A liquid processing system or heat reclaim purification (“HRP”) system discloses a purification process with heat regenerating using one or more heat exchangers. The HRP system, in one embodiment, containing a heat reclaiming device or heat exchanger(s) includes a first set of thermal conductive channels (“TCC”), a second set of TCC, and a third set of TCC. The first set of TCC configured in a first heat exchanger (“HE”) is arranged in cylindrical shape able to enclose or surround a main boiler. A function of the first set of TCC is to guide a first liquid flow to flow through the first HE. The second set of TCC configured in a second HE is also arranged in cylindrical shape and is able to guide a second liquid flow to flow through the second HE. The third set of TCC, which is configured to thermally couple to the first and second sets of TCC, guides a third liquid flow to flow through the first and the second HEs. In one aspect, the third liquid flow, which is a cold water stream, flows through the third set of TCC adjacent to the first set of TCC and extracts heat from the first liquid flow such as a hot purified water, via the first set of TCC and the third set of TCC. A manifold is used to provide some separation between the first HE and second HE.

- Heat Reclaim Purification (“HRP”) System
- Embodiments of the present invention discloses a liquid or water purification apparatus capable of purifying liquid or water using regenerative heat exchanger. The apparatus includes a liquid receptacle, a heat exchanger, a heating mechanism, a compressor, and a condenser. The liquid receptacle, for example, is able to receive a stream of liquid such as water or liquor. In one embodiment, the liquid receptacle includes a water-input receptacle capable of receiving a flow or stream of water from an external device. The stream of water, for example, is pressurized having a range from two (2) pounds per square inch (“PSI”) to 500 PSI. The water has a molecular structure of one oxygen and two hydrogen atoms connected by covalent bonds (“H2O”).
- The heat exchanger, in one aspect, pushes or forces the received stream of liquid through the heat exchanger to preheat or increase the temperature of the liquid via at least a portion of processed liquid. The heat exchanger further includes a top or main heat exchanger and a bottom heat exchanger. While the top heat exchanger is configured to preheat incoming water with the purified water, the bottom heat exchanger preheats incoming water with the discarded water. Alternatively, the top heat exchanger is also configured to extract heat from purified water with incoming water before the purified water leaves the apparatus. The bottom heat exchanger cools down discarded water with incoming water before the discarded water leaves the apparatus as waste water.
- The heating mechanism generates heat to facilitate phase transition from liquid to vapor. In one embodiment, the heating mechanism has a heater configured to heat water to a boiling point to separate purified water from impurities. The heating mechanism includes a heater, such as a burner, a magnetic inductance heat generator, resistance heating element, et cetera.
- The compressor guides or forces the vapor through the condenser, wherein the compressor includes a turbine operable to create a directional vapor whirlpool inside of a boiler to force the vapor into the condenser. In one embodiment, the compressor creates a vacuum to alter the boiling point for the liquid or water to speed up the separation of purified water from incoming water.
- The condenser condenses vapor into liquid or purified liquid before it leaves the apparatus. The condenser further includes a set of blades or flutes wherein each blade is shaped in such a way that it optimizes liquid condensation from vapor to purified water. In one embodiment, the liquid purification apparatus also includes a housing which is configured to house the heat exchanger which is configured to fit both the compressor and condenser in the middle of heat exchanger.

FIG. 1A is a diagram illustrating an exemplary heat profile or temperature profile during a liquid purification process in accordance with one embodiment of the present invention. Diagram illustrates a cross-section side view of a heat reclaim purification (HRP)system 100 capable of processing or purifying liquid, such as water, or any other liquid that could be purified by distillation process.HRP system 100 includes acondenser 110 having aninput port 101 and anoutput port 102 whereininput port 101 receives gas such as water vapor whileoutput port 102 releases processed liquid such as purified water. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 100. -
FIG. 1A illustrates a computer simulated heat or temperature profile ofHRP system 100 during a water purification process using regenerative heat exchanger wherein the water vapor or vapor entersinput port 101. In one embodiment, when water vapor is being rushed or forced intocondenser 110 as a fast moving vapor jet or stream via a compressor, not shown inFIG. 1A , the fast moving vapor creates adirectional vapor whirlpool 108 inside the condenser. The heat profile illustrates a main stream ofdirectional vapor jet 105 moving frominput port 101 tooutput port 102. The warmest or hottest area of the heat profile, in one aspect, is indicated by numeral 104 while the coolest area is indicated bynumeral 103. In one aspect of the present invention,condenser 110 is able to produce purified water in accordance with the heat profile, and is capable of recapturing, regenerating, or reclaiming heat (or energy) released from phase transition between vapor and liquid. For example, vapor stream entering frominput port 101 and exitingoutput port 102 as liquid gives off heat during the phase transition. - A regenerative heat exchanger facilitates two flows or streams of fluid or liquid such as coming water and exiting purified water to flow through a heat exchanger in logically opposite direction or in a configuration of countercurrent exchanger. The heat exchanger having components, such as pipes, tubes, and/or channels, is able to maintain two moving flows separated while physically adjacent with each other to facilitate heat exchange. The heat or temperature profile may remain at a nearly constant temperature which includes the entering flow (cold or ambient water) and exiting flow at each end. In regenerative heat exchangers, in one example, uses a cyclical and/or repetitive treatment or process to preheat the incoming cold water via heat released by the processed water. The processed water includes purified water and discarded water. The discarded water is also known as waste water which contains relatively high concentration of impurities.
- To operate, incoming cold water enters the heat exchanger and is preheated by heat extracted from processed water exiting the heat exchanger. The regenerative heat exchanger is able to conserve energy since a large amount of the heat energy is reclaimed or recaptured in a thermodynamically reversible way. Depending on the applications, the heat exchanger can have a range of thermal efficiency from 50% to 95% by transferring heat energy from a hot directional water flow to a cold directional water flow.
- To condense vapor into purified water in accordance with the heat profile as illustrated in
FIG. 1A ,condenser 110 employs multiple blades orflutes 106 according to main stream ofdirectional vapor jet 105 as illustrated inFIG. 1B . In one embodiment,blade 106 includesvapor section 116,phase changing section 118, andliquid section 120, wherein thephase changing section 118 releases heat since the water molecule gives off energy when it transforms its physical formation from vapor (or gas formation) to liquid (or fluid formation). Depending on the applications, the shape of blade orflutes 106 may change in accordance with the vapor jet. It should be noted that the term “blade” and “flute” are used interchangeably herein. Also, the term “vapor” and “water vapor” are used interchangeably herein. - Water is a chemical substance having a chemical formula H2O wherein its molecule structure contains one oxygen and two hydrogen atoms connected by covalent bonds. Depending on the temperature, water can be in different physical formation. For example, water is in a liquid formation at ambient or room temperature. Water is in vapor, steam, gas (or gaseous) formation when the temperature is at or above water's boiling point. It should be noted that the description uses water and/or water vapor as an exemplary chemical substance and the underlying concept of
HRP system 100 is applicable to any other chemical substances capable of changing their physical formation in view of their boiling points as well as environmental pressure. - The boiling point of a chemical substance such as water is a temperature wherein vapor pressure of fluid is similar to surrounding or environmental pressure over the fluid or liquid. If the chemical substance in its liquid formation such as water, it has a lower boiling point in a low pressure or vacuum environment than when the water is at atmospheric pressure. Similarly, water or liquid has a higher boiling point in a high pressure surrounding than the water is at atmospheric pressure. As such, different chemical substance having different chemical compounds possesses different boiling points. Accordingly, the fluctuation of boiling point for a particular chemical substance such as water is a function of temperature and pressure.

With respect to diagram 100,input port 101 is situated on the top ofcondenser 110 at the lower left corner whileoutput port 102 is situated at the bottom of upper right corner ofcondenser 110. A directional steam orvapor jet 152 is formed whereby pressurized vapor jet enteringinput port 101 and exitingoutput port 102 according to a vaporflow traveling path 155. In one aspect, the heat exchange occurs atarea 154 which is generally the hottest/warmest spot in thedirectional vapor jet 152. It should be noted that converting water into vapor requires sufficient energy required to vaporize water into vapor. -

The shape ofblade 106 is structured and/or configured in accordance with the shape ofdirectional vapor jet 105 as shown inFIG. 1A .Blade 106 includes aninput port 101 and anoutput port 102. Depending on the applications, the shape ofblade 106 may vary. For example, a narrow section 203-204 ofblade 106 may change depending on volume and speed of vapor flow.FIG. 3 illustrates a three dimensional (“3D”) view ofblade 106 withinput port 101. In one aspect, the area pointed bynumeral 304 is the warmest area while the area pointed bynumeral 303 is the coolest in the condenser. -
FIG. 4 is an isometric diagram 400 illustrating a turbine and condenser blades for liquid purification process in accordance with one embodiment of the present invention. Diagram 400 shows a structural layout between aturbine 405,multiple blades 404, and aflow guide 406.Turbine 405, in one embodiment, includes a motor and turbine blades configured to create a vacuum or low pressure area in the vicinity offlow guide 406. The motor and turbine blades, for example, can be fabricated by any applicable materials, such as aluminum, stainless steel, plastic, polymer, alloy, ceramic, and/or a combination of one or more of aluminum, stainless steel, plastic, polymer, alloy, and ceramic. The turbine provides a vacuum area above the incoming liquid (water) and reduces the boiling point of the liquid. The turbine acts as a compressor lowering the pressure whereby reducing boiling point of the liquid. Atop plate 401 is used to anchor and/orsecure turbine 405 as well as blades or flutes 404. -
Flow guide 406, which may be in a cone shape, is configured in such a way that it creates and guides a directional vapor whirlpool between heat source, not shown inFIG. 4 , andturbine 405 in response to the vacuum generated byturbine 405. During an operation, upon creation of the vacuum, one or more directional vapor flows are generated in accordance with the directional vapor whirlpool. The directional vapor flows are subsequently guided, pushed, and/or forced into input ports 402-403 of blades orflute 404. When vapor flows are highly compressed and pass through narrow portions offlutes 404, the physical phase transition takes place as vapor flows are condensed into purified water. The heat or energy released as a result of phase transition is added to the heat source to generate more vapors. Note thatturbine 405 and flowguide 406 are at least part of compressor. -

In one embodiment,main boiler 502 is used to process or produce purified water while bottom boiler-collector 508 is used to process or discard the waste water, substances with impurities, and/or discarded water. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 500. - Upper-
manifold 509 is coupled toturbine 503,blades 404, and flowguide 406. A function of upper-manifold 509 is to distribute vapor flows frommain boiler 502 toblades 404 via variousmanifold channels 504 aftervapor 501 is drawn up byturbine 503 from the bottom ofmain boiler 502 near the heat source to the top ofmain boiler 502. In an alternative embodiment, a compressor, which includesturbine 503 and flowguild 406, is coupled to upper-manifold 509 to create a vacuum area near the top ofmain boiler 502 for generating a directional vapor whirlpool. - The vapor flows are pressurized and condensed at the narrow regions of
condenser blades 404 aroundepic center 505 which is the area that heat exchange occurs. In one aspect,epic center 505 is hottest or warmest area inmain boiler 502.Epic center 505 is created when pressurized vapor flows through narrow portions offlutes 404 and the physical phase transition takes place aroundepic center 505. When vapor is condensed into purified water, heat or energy is released as a result of phase transition. -

It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 1400. - In one embodiment,
heat exchanger 1430 andbottom heat exchanger 1432 are interconnected whereinheat exchanger 1430 uses multiple pipes and/or tubes to extract heat from purified water when it passes throughheat exchanger 1430.Bottom heat exchanger 1432 also employs various tubes to extract heat from waste water when it passes throughbottom heat exchanger 1432.

Note that the liquid is on outside of heat exchange tubes and the vapor and condensed liquid is on the inside of heat exchanger tubes. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or blocks) were added to or removed from diagram 1500. -
FIG. 16 is a diagram 1600 illustrating an exploded view of a main assembly or HRP system configured to process liquid using heat regenerative mechanism in accordance with one embodiment of the present invention. Diagram 1600 showsboiler 502,bottom boiler 508,heat exchanger 1430, andbottom exchanger 1432, whereinboiler 502 andbottom boiler 508 are structured such that they can fit inside of heat exchanger 1430-1432. - In one aspect, HRP system includes a boiler, turbine, condenser, heat exchanger, and feed pump(s). The system operates under the principles of the regenerative cycle. The condenser exchanges heat with water in the boiler, and the heat exchanger acts to preheat incoming water, while cooling outbound processed and waste water. In an operation, water enters the boiler where it is heated past the critical point, and steam is generated. The turbine draws a vacuum in the boiler and forces the steam through a manifold and through the condenser. Since the boiling points of impurities normally found in water are higher than the boiling point of water, the water vapor is assumed to be pure as it flows through the turbine. The mechanism of injecting water into the boiler, in one example, promotes rotational flow within the main body, shaping the flow as it approaches the turbine.
- Additionally, the configuration of the blades in the condenser is such that heat transfer back into the bulk media is at a maximum by optimizing the level of wetted surface area. The shape of the blades and their configuration also serves to smooth flow of steam through the boiler and into the turbine. The flow of purified water through the condenser splits into 1 of 2 intake manifolds, each one serving a respective bank of condenser blades. The manifolds feed into identical counter flow heat exchangers, which use incoming feed water as the cold working fluid, and exiting purified and exiting waste water as the hot working fluid. The use of symmetry is meant to promote optimal efficiency by precisely managing the thermal gradient within the control volume. The shape of the blades is aimed to correspond with the proposed water fill line. This entire system is wrapped by a skin of stainless steel, and the heat exchangers will be placed on either side of the condenser banks.
- The exemplary aspect of the present invention includes various processing steps, which will be described below. The steps of the aspect may be embodied in machine or computer executable instructions. The instructions can be used to cause a general purpose or special purpose system, which is programmed with the instructions, to perform the steps of the exemplary aspect of the present invention. Alternatively, the steps of the exemplary aspect of the present invention may be performed by specific hardware components that contain hard-wired logic for performing the steps, or by any combination of programmed computer components and custom hardware components.

FIG. 17 is a flowchart illustrating a process of liquid purification using heat regenerative mechanism in accordance with one embodiment of the present invention. Atblock 1702, a process capable of implementing regenerative heat exchange receives a stream of cold water from an external device, such as a municipal water supply company, river, well, pond, reservoir, or the like. Upon activating heat extracting pumps in response to water pressure provided by the stream of cold water, the process pushes or pumps purified water through the heat exchanger for transferring or extracting heat from purified water to the stream of cold water. The process also pushes or forces the discarded liquid such as waste water through the heat exchanger to extracting heat from the discarded liquid to preheat the stream of water. - At
block 1704, when the stream of cold water enters the heat exchanger for preheating as the stream passes through the heat exchanger, water in the stream is heated to its boiling point when it reaches to the epic center. Atblock 1706, the stream of water is separated between purified water and waste water by converting a portion of water into vapor. Atblock 1708, a directional vapor whirlpool is generated inside of a boiler to push the vapor into a set of flutes for condensation. - At
block 1710, the flutes or blades in the condenser condense vapor into purified water. The process forces the vapor through a set of angular shaped flutes capable of facilitating regenerating heat exchange between the angular shaped flutes. The purified water is subsequently pumped into the heat exchanger for heat extracting. The heat extracting or heat exchange occurs when hot pipes or tubes in the heat exchanger carrying hot purified water pass adjacent to cold pipes or tubes in the heat exchanger carrying the stream of cold water wherein the heat extracted from purified water preheats the incoming cold water. The hot waste water, on the other hand, is allowed to flow into the heat exchanger for heat extracting or heat reclaiming process. The heat reclaiming process occurs when hot pipes in the heat exchanger carrying the waste water pass adjacent to cold pipes in the heat exchanger carrying the stream of cold water. Upon activating heat extracting pumps in response to water pressure provided by the stream of water, the purified water is pushed through the heat exchanger for transferring heat from the purified water to the stream of water. The discarded liquid is also pumped through the heat exchanger for preheating the stream of water. - Heat Exchanger (“HE”) in HRP System
- A liquid processing system, also known as HRP system, discloses a liquid purification process using one or more HEs to reclaim or regenerate heat. The HRP system, containing one or more HEs which are also known as heat reclaiming devices, includes a first set of thermal conductive channels (“TCC”), a second set of TCC, and a third set of TCC. A manifold is used to conditionally separate the first HE from second HE. Note that the first HE can also be referred to as top HE and the second HE is referred to as bottom HE. In one example, the manifold, also known as center manifold, allows the third set of TCC to pass through the manifold while prevents the first and second sets of TCC from passing through the manifold.
- The first set of TCC configured in the top HE is arranged in a cylindrical shape that is able to enclose or surround a main boiler. The first set of TCC is operable to guide a first liquid flow to flow through the top HE. Note that the first liquid flow can be hot purified water. The second set of TCC is configured in the bottom HE and it also has a cylindrical shape. The second set of TCC is able to guide a second liquid flow to flow through the bottom HE. Note that the second liquid flow can be waste water or liquid with impurities.
- The third set of TCC, which is configured to thermally couple to the first set of TCC and the second set of TCC, is able to guide a third liquid flow through both the top HE and the bottom HE. The third liquid flow, in one example, is cold tap water, running water, river water, and the like. The third liquid flow, for example, flows through the third set of TCC and is able to extract or absorb heat from the first liquid flow and/or second liquid flow via the thermal connectivity between the first, second, and third sets of TCC.

FIG. 18 illustrates a three-dimensional (“3D”) view ofHRP system 1800 using an HE to reclaim heat during a purification process in accordance with one embodiment of the present invention.HRP system 1800 includes aboiler assembly 1805 and anHE 1810 wherein HE 1810 includestop HE 1826 andbottom HE 1836.Boiler assembly 1805 includes aturbine assembly 1806, amain boiler 502 and aliquid collecting panel 508. It should be noted that the underlying concept of the exemplary embodiment(s) of the present invention would not change if one or more components (or devices) were added to or removed fromsystem 1800. -
Top HE 1826, which is similar toHE 1430 shown inFIG. 14 , includes multiple thermal conductive channels (“TCC”) structured in multiple cylindrical shaped rings (“CSRs”) 1820-1824. CSRs 1820-1824, in one embodiment, are formed with multiple nested concentric cylinders whereinCSR 1820 is the innermost cylinder whileCSR 1824 is the outermost cylinder.Multiple cylinders 1822 are situated betweenCSR 1820 andCSR 1824 forming a multiple layered heat recovery or heat exchange device. CSR is made of thermal conductive materials, such as aluminum, metal, thermal conductive composite, and/or alloy, able to transmit heat between CSRs 1820-1824. Note that each CSR has a unique diameter whereby it can fit within neighboring CSRs to form an HE. - CSRs 1820-1824, in one embodiment, are configured to include hot TCC and cold TCC in an alternating arrangement. The alternating arrangement refers to hot TCC and cold TCC are structured in an alternate configuration whereby cold TCC can absorb heat from hot TCC. In one example, each cold TCC is situated adjacent to at least one hot TCC. In one aspect, most of cold TCC are switched by two hot TCC wherein the two hot TCC may facilitate passage of one or two hot liquid flows. Note that hot liquid flow can be purified water or waste water. Cold liquid flow can be tap water. Since
HE 1826 is configured in the alternating arrangement, most of hot TCC are also switched by two cold TCC. For example, a flow of hot water travels ups and downs several times within the TCC to transfer its heat from hot water to cold water. Depending on the applications, the temperature of purified water at outlet port should be around room temperature since most of the heat carried by purified water is dissipated or transferred through TCC. The cold water or supply water, on the other hand, should be relatively warm or hot when the water reaches atboiler 1808 ready for processing. Warm supply water is generated partially because cold water absorbs heat from hot water via TCC or CSRs. -
Bottom HE 1836, which is similar toHE 1432 shown inFIG. 14 , includes multiple TCC structured in CSRs 1830-1834. CSRs 1830-1834, in one embodiment, are formed by multiple nested concentric cylinders whereinCSR 1830 is the innermost cylinder whileCSR 1834 is the outermost cylinder.Multiple cylinders 1832 are situated betweenCSR 1820 andCSR 1824. CSR can be made of thermal conductive materials, such as aluminum, metal, thermal conductive composite, and/or alloy, for transmitting heat across CSRs 1830-1834. Note that each CSR has a unique diameter whereby it can fit between neighboring CSRs inHE 1836. - CSRs 1830-1834, in one embodiment, are configured to include hot TCC and cold TCC in an alternating arrangement. The alternating arrangement of CSRs refers to each cold TCC is adjacent to at least one hot TCC. In some cases, a cold TCC is switched by two hot TCC wherein the two hot TCC may facilitate passage of one hot liquid flow such as waste water. For example, a flow of hot water travels ups and downs several times within the TCC in bottom HE 1836 to transfer its heat from the flow of hot water to a flow of cold water such as tap water or river water. Depending on the applications, when waste water exits HRP system, its temperature should be closer to room temperature by dissipating its heat through the TCC while the cold water or supply water should be fairly warm when it reaches to
boiler 1808 because it absorbs heat from hot waste and purified water via TCC. - During a purifying process,
top HE 1826 reclaims or absorbs the heat from the processed liquid generated byboiler assembly 1805, whilebottom HE 1836 reclaims the heat from waste liquid such as waste water generatedboiler assembly 1805 before it exitsHRP system 1800. To reclaim or recover the heat, a cold liquid flow such as tap water or river water is used to extract heat from the processed or waste liquid before they leaveHRP system 1800. The cold liquid flow, however, absorbs the heat from bothtop HE 1826 and bottom HE 1836 by traveling throughHEs boiler 1808. - An advantage of using an HE is that it is able to reclaim the heat from processed liquid and waste liquid by transferring the heat to the cold unprocessed liquid.
-
HRP system 1800, which can also be referred to as a liquid processing system, is capable of recovering heat via a heat reclaiming device.System 1800 includes a top set of hot TCC, a bottom set of hot TCC, and a cold set of TCC. The top set of hot TCC, configured to be intop HE 1826 having a cylindrical shape, is configured to surround a main boiler orboiler 1808. The top set of hot TCC is operable to guide a hot processed liquid flow such as purified water stream to flow throughtop HE 1826. - The bottom set of TCC, configured to be in
bottom HE 1836 having a cylindrical shape, is operable to guide a waste liquid flow such as waste water stream to flow throughbottom HE 1836. A manifold orcentral manifold 506 is situated betweentop HE 1826 andbottom HE 1836. In one aspect,central manifold 506 is used to separate between the purified liquid flow and waste liquid flow while allowing cold liquid flow to pass through. - The cold set of TCC is thermally coupled to the top set of TCC and bottom set of TCC for guide a cold liquid flow to flow through both
top HE 1826 andbottom HE 1836. For example, the cold liquid flow flows through the cold set of TCC adjacent to the top set of TCC and extracts heat from the hot processed liquid flow via the top set of TCC and the cold set of TCC.Center manifold 506 allows the cold liquid flow to travel from one side ofcenter manifold 506 to another side allowing the cold liquid flow to absorb heat from hot waste liquid flow as well as hot purified liquid flow. - The top set of TCC, in one embodiment, includes multiple top concentric cylinders or CSRs 1820-1824 which are configured to form
top HE 1826.Top HE 1826, in one example, accumulates heat from processed or heated liquid generated bymain boiler 1808. Each of top concentric cylinders has a unique diameter so that every top concentric cylinder can fit in one or two neighboring cylinders. Note that top HE uses various concentric cylinders or CSRs 1820-1824 to form a hollow column. WhileCSR 1820 adjacent toboiler 1808 has the smallest CSR diameter.CSR 1824 situated at the outmost oftop HE 1826 has the largest diameter. - In one embodiment,
top HE 1826 includes a hot conduit and a cold conduit wherein the conduits includeguide ridges 1842 for guiding liquid flows. In an alternative embodiment,top HE 1826 includes multiple sets of hot conduits and cold conduits. The hot conduit, in one example, includes the top set of TCC and the cold conduit includes a portion of the cold set of TCC. The cold liquid flow, for example, can travel through the cold conduit absorbing heat transmitted from a hot liquid flow via the hot conduit. It should be noted that the cold liquid flow can be room temperature or ambient temperature of water stream, while the hot liquid flow such as purified water stream can be close to liquid boiling temperature. -
Bottom HE 1836 includes CSRs 1830-1834 containing bottom set of TCC. Each of bottom CSRs 1830-1834 has a unique diameter allowing a larger bottom concentric cylinder to house or enclose a smaller bottom CSR whereby all CSRs 1830-1834 collapse into a single column configuration.Bottom HE 1836 includes at least one hot conduit and one cold conduit wherein the conduits, in one example, includeguide ridges 1848 for guiding the flow(s). The cold conduit, in one example, includes a portion of cold set of TCC able to facilitate heat transfer between the hot conduit and the cold conduit. Note that bottom HE 1836 may include multiple sets of hot and cold TCC. It should be noted thattop HE 1826 and bottom HE 1836 include guiding mechanism configured to direct and/or pump liquid flows in predefined directions. - An advantage of employing HE 1810 in HRP system 300 is that
HE 1810 guides processed or purified hot liquid flow(s) to travel through thermally conductive pipes multiple times to recover heat from the hot liquid flows. The recovered heat is stored in the incoming cold liquid flow. -

The hot set of TCC and the cold set of TCC are arranged in alternative sequence between the nested layers for thermal conductivity. The hot set of TCC is able to carry a processed hot liquid flow and the cold set of TCC is able to carry or transport a cold liquid flow whereby the cold liquid flow is allowed to absorb heat from the processed hot liquid flow. It should be noted that the terms “processed hot liquid” “purified hot liquid” “processed liquid” “purified liquid” “distill water” and “purified water” are referred to the same or similar liquid substance. -

Top HE 1826 and bottom HE 1836 further include guide ridges 1842-1848 used for guiding flow directions. For example, a purified water flow may travel in a direction according to flow guide ridges or guide ridges 1842-1844. Similarly, a waste water flow may flow in a direction according to flow guide ridges 1846-1848 inbottom HE 1836. Note that guide ridges 1842-1848 may be fabricated or structured as part of TCC or CSRs. -

The surfaces of concentric cylinders are structured with flow guide ridges 1842-1844. - In operation, flow guide ridges 1842-1844 direct liquid flow(s) running through the gaps to predefined directions. The predefined directions include defined flow patterns which, for example, can be a helical flow formation. In one example, heights of flow guide ridges 1842-1844 from surface of concentric cylinders are similar or the same between adjacent cylinders.

Flow guide ridges such as ridges 1842-1848, in one aspect, are physically protruded to form ridges on the surface of CSRs. In one example, flow guide ridge is oriented in a slanted angle relative totop manifold 509 orcenter manifold 506. When liquid flows within TCC between CSRs, flow guide ridge 1842-1848 can guide the flow(s) in orientations conforming to angle of flow guide ridge 1842-1848. - In one aspect,

When the purified water flow is about to leave the top HE, the majority of its heat should have been passed onto the incoming cold water flow. - Diagram 2102 illustrates a cross-section view of bottom HE 1836 containing multiple CSRs 1830-1834 wherein each CSR is arranged to have a gap or space between its neighboring CSR(s). The space between CSRs, in one embodiment, is arranged to form hot TCC such as flow channels 2142-2146 and cold TCC such as flow channels 2132-2136. During an exemplary operation, after a purified water flow leaves a boiler, the purified water flow, in one example, enters
flow channel 2120 through inlet onCSR 1820. - During an exemplary operation, after a waste water flow leaves a boiler, the waste water flow enters
flow channel 2142 through inlet onCSR 1830. The waste water flow travels through channels 2144-2146 while transferring its heat to a cold (unprocessed) water flow flowing through flow channels 2132-2138. When the waste water flow is about to leave the bottom HE, the majority of its heat should have been passed onto the incoming cold water flow. - Flow channels 2110-2126, in one example, are separated into a hot group and a cold group, wherein the groups are arranged in alternating sequences. For example,
hot flow channel 2122 is placed next tocold flow channel 2116 andcold flow channel 2116 is further placed next tohot flow channel 2124. Processed liquid exiting from the boiler has a higher temperature than the incoming or unprocessed liquid. The alternating sequence arrangement of flow channels provides heat exchange between the hot processed liquid and the cool incoming liquid in the hot and cold groups of flow channels. -

In one aspect,center manifold 506 includes an inlet orinlet port 2212 for receiving processed liquid 2206 from the boiler, and an outlet oroutlet port 2210 for discharging processed liquid 2208 such as purified water. It should be noted that inlet and/or outlet can be placed at other locations such asupper manifold 507 ortop HE 1826. - In operation, when processed
liquid flow 2206 travels through flow channels 2120-2126, a cold liquid flow orunprocessed liquid flow 2218 also travels through flow channels 2110-2118. Theunprocessed liquid flow 2218 absorbs heat from processedliquid flow 2206. When processedliquid flow 2206 reaches atoutlet 2210, it becomes a lukewarm or room temperature wherein majority of heat inflow 2206 has been transferred or stored atcold liquid flow 2218. - Diagram 2202 illustrates an exemplary cross-section side-view of bottom HE 1836 coupled with

It should be noted that inlet and/or outlet can be placed at other location(s) depending on the applications. - In operation,
unprocessed liquid flow 2218 entersinlet 2268 and travels through flow channels 2110-2116 as indicated by arrows before it exits atoutlet 2270 and subsequently enters the boiler. Whenunprocessed liquid flow 2218 travels through flow channels 2110-2116, processedliquid flow 2206 also travels throughtop HE 1826 andwaste liquid flow 2215 travels throughbottom HE 1836. When hot and cold liquid flows 2206, 2215, 2218 pass next to each other through their own flow channels, the heat in hot liquid flows 2206 and 2215 passes tocold liquid flow 2218 whereby the heat is removed from hot liquid flows and stored in the cold liquid flow. Whenunprocessed liquid flow 2218 reaches tooutlet 2270, it becomes relatively warm since the majority of the heat inflows cold liquid flow 2218. - Note that the locations of inlet and/or outlet ports are not limiting to the example illustrate herein. Heated waste liquid exiting from the boiler enters
inlet port 2258 and then passing throughflow channel 2142,connecter 2260,flow channel 2144,connecter 2256, and then flowchannel 2146 before discharged viaoutlet port 2216.
