FIELD OF THE INVENTION

[0002] The present invention relates to systems clean coal fire power plant exhaust gases by separating particulate materials and decomposing carbon dioxide gas.

BACKGROUND OF THE INVENTION

[0003] The following discussion is provided solely to assist the understanding of the reader, and does not constitute an admission that any of the information discussed or references cited constitute prior art to the present invention.

[0004] The anthropogenic generation of the greenhouse gas carbon dioxide (CO2) is generally recognized as a significant contributing factor in climate warming. As a result, many different approaches have been proposed for reducing such release, with the majority focusing on carbon sequestration and/or recycling.

SUMMARY OF THE INVENTION

[0005] Anthropogenic greenhouse gas emissions are generally accepted as being a significant fact in climate warming. A major component of such greenhouse gases is carbon dioxide (CO2). As a result, reducing the release of carbon dioxide has become an important consideration. The present invention address this problem by providing a system for significantly reducing CO2 emissions from gases, especially exhaust gases (e.g., exhaust gases from coal fired power plants). The system involves devices or components which filter the gas stream to remove particulates, converts CO2 to carbon and oxygen and separates out the carbon. The system can also include a filter for removing carbon particles from an electrolyte solution used in the CO2 converter, thereby increasing its useful lifetime.

[0006] Thus, a first aspect of the invention concerns a system for cleaning C02-containing gases and decomposing CO2, where the system includes a fiber- based exhaust gas particle filter and a CO2 decomposition and separation device having gas passage connection with the outlet of the fiber-based exhaust gas particle filter. The CO2 decomposition and separation device utilizes an electrolyte solution in decomposing CO2. Advantageously the system may also include an electrolyte filter which filters carbon particles from the electrolyte.

[0007] In particular advantageous embodiments, the fiber-based exhaust gas particle filter is a spiral frame filter; the exhaust gas particle filter is a filter as specified for an embodiment of the spiral frame filter below or otherwise described herein; the electrolyte filter is a declined angle filter, such as specified for an embodiment of electrolyte filter below or otherwise described herein.

[0008] A related aspect concerns an exhaust gas filter which is a spiral frame filter in which the filter material is mounted in spiral manner about a central rotational shaft.

[0009] In particular embodiments the filter includes a tank having exhaust gas inlet and outlet connections, and having rotatably mounted therein a spiral shaped filter element. The filter element can, for example, include a spiral shaped frame attached to a central shaft with a metal net (or other substantially perforated and preferably substantially rigid support surface (preferably ferrous metal) attached to the spiral shaped frame and substantially spanning the space between the frame and the shaft; a filter panel which includes a fiber mounting disk with a large number of fibers attached to a surface thereof, mounted on the spiral shaped frame and the metal net or other support surface.

[0010] In certain cases, the spiral shaped frame is attached to the central shaft with at least one locking collar; the fibers are attached in a large number of fine holes in the fiber mounting disk; the filter frame and/or the metal net or other support are primarily made of ferrous metals; the filter panel is magnetically mounted to the spiral frame and/or the metal net (usually for ferrous metal spiral frames and/or support surfaces.

[0011] Also in certain embodiments (especially for ferrous metal spiral frames and/or supports, the filter panel is mounted on the spiral frame and metal net (or other support with a gap adjusting panel attached to the fiber mounting disk with a magnetic sheet attached to the gap adjusting panel; the gap adjusting panel is attached to a magnetic sheet installation which is attached (e.g., glued) to the magnetic sheet.

[0012] Further advantageous embodiments include a washer (e.g., a spray washer) which washes particles from said fibers; the washer includes a plurality of washing water nozzles fluidly connected with a wash water supply line.

[0013] In still further advantageous embodiments, the filter includes a plurality (e.g., 2, 3, or 4, or at least two filter tanks connected in parallel; parallel connection filter tanks include gas switching valves installed in the exhaust gas inlet connection pipes and exhaust gas outlet connection pipes for the filter tanks to control the flow of the exhaust gas through the tanks (e.g., a valve for the inlet and outlet for each tank or for each parallel tank set, such that the valves can isolate each tank from the other or others, or each set of tanks from another set or sets). [0014] Yet another related invention concerns an electrolyte particle filter which includes an outer body, and a declined, conveyor-mounted fiber particle filter mounted within the outer body.

[0015] In particular embodiments, the electrolyte particle filter includes an electrolyte feed pipe which supplies electrolyte at or near the top of the declined, conveyor-mounted particle filter, and an electrolyte return pipe which removes filtered electrolyte after passage over the declined, conveyor-mounted particle filter; the filter includes rotatable conveyor rolls with a conveyer belt bearing a carbon collection fiber filter to collect carbon microparticles from the electrolyte, an may further include a washer which washes carbon particles from the carbon collection fiber filter, creating a carbon particle suspension. Such carbon particle suspension can be past to a carbon particle separation which separates carbon particles from electrolyte solution, e.g., a centrifugal separator which receives the suspension from the carbon collection fiber filter.

[0016] Also in particular embodiments, the electrolyte particle filter of also includes an angle adjustor which adjusts the declination angle of the filter (e.g., by adjusting he declination angle of the outer body or the declination angle of the conveyor rolls and conveyor mounted filter.

[0017] Additional embodiments will be apparent from the Detailed Description and from the claims.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0048] Carbon dioxide (CO₂) is the most prevalent, ubiquitous and cited greenhouse gas produced by anthropogenic activities. Greenhouse gases are widely believed to cause or at least significantly contribute to global warming. The present invention addresses the problem of anthropogenic CO₂ by providing a practical system to decompose the CO₂ gas to carbon and oxygen and can significantly contribute to easing the global warming problem. This devise can be produce cheaply throughout the world.

[0049] Thus, this invention can decompose and separate the CO₂ gas into carbon and oxygen and eliminate the CO₂ gas, but for many sources, fine particles in the CO₂-containing gases present processing difficulties. The system of this invention uses a spiral shaped frame and a synthetic fiber to filter those very fine particles included in the CO₂ gas before the CO₂ gas is sent into the CO₂ reduction system to decompose and separate the CO₂ gas.

[0050] In addition, the electrolyte solution used for decomposition and separation of the CO2 gas will absorb the carbon separated from CO2 gas, and the quantity of the carbon in the electrolyte will increase with repeated use of the electrolyte solution. As a result, the decomposition and separation efficiency of the electrolyte solution will be degraded. This invention uses a declined angle devise to let the electrolyte solution flow through a synthetic fiber and the carbon will stick between those gaps on the synthetic fibers. In an exemplary system, about 70 % of the carbon will be trapped, and therefore the electrolyte can be used more times.

[0051] With this invention, the CO2 gas will flow to the first device (first major system component) which uses a spiral shaped synthetic filter to clean the fine particles contained in the CO2 gas, the second device (second major system component) will then perform the decomposition and separation of the CO2 gas, and the third device (third major system component) uses a declined angle device to allow the electrolyte to flow through the carbon collection filter. With this design a very low cost and high efficiency system can be manufactured to perform the decomposition and separation of CO2 gas. [0052] This invention is especially well-suited to collect the very fine particles from coal or coke exhaust gases.

[0053] Fig. 8 is a schematic block diagram showing an exemplary total system designed to clean the fine particles and eliminate the CO2 gas from a factory's or power plant's exhaust gas, and also to collect the carbon produced from decomposition of CO2. As shown schematically in Fig. 8, exhaust gas from source 39 is directed into the spiral shaped fiber filter device 40. After passing through the filter device, the exhaust gas flowing from the spiral shaped fiber filter 40 will be fed to the CO2 decomposition and separation device 41 where the CO2 gas is decomposed and separated. Electrolyte from the CO2 decomposition and separation device is passed over declined angle carbon filter 42. Recovered carbon particles can then be collected in carbon collection device 43. The system is controlled by control box 50. A control box 50 is shown schematically in Fig. 9.

[0054] By collecting the carbon from the electrolyte, the quantity of electrolyte used in the CO2 decomposition and separation device 41 is reduced. In addition, the collected carbon becomes a resource. The carbon separated from CO2 is very fine, therefore, can, for example, be used to produce artificial diamond.

[0055] This is an exhaust gas cleaning system using a group of devices working together to take the exhaust gas emitted from a factory or power plant, and run the exhaust gases through the spiral shaped fiber filter exhaust gas filter device 40, the CO2 decomposition and separation device 41 , and the declined angle carbon filter device 42 to clean the fine particle and eliminate the CO2 gas from the exhaust gas. Finally, the carbon decomposed and separated from CO2 can be collected by the carbon collection devise 43. Details of exemplary system components are shown below. The CO2 decomposition and separation component is described in Niioka, US Patent Applications 12/072,059, and 12/188,681 , both of which are incorporated herein by reference in their entireties, including drawings.

A. Design and setup of an exhaust gas filter using a spiral shaped frame fiber filter [0056] In the illustrated example as shown in the upper portion of Fig. 1 , a portion 1 a of a spiral shaped filter frame is shown attached to (e.g., mounted on) a central shaft. The full-length spiral frame 1 b is shown in the lower portion of Fig. 1 , mounted on the shaft 4c. A connection metal fitting 2 is used to connect the frame to the shaft and is fixed in place with bolts in bolt holes 6. Of course, the frame could be attached to the shaft in other ways, e.g., by welding. Also mounted on the shaft are carrier bearings 4a and 4b, as well as drive pulley 5. Metal net 3 spans the space between spiral frame 1 b and shaft 4c.

[0057] Details of an exemplary construction for the spiral shaped filter are shown in Fig. 2A, Fig. 2B, Fig. 2C, and Fig. 2D. Fig. 2A shows a cross-sectional view of the spiral frame portion 1 a (same as 1 b) with attached metal net 3 mounted on shaft 4c. As shown in Fig. 2B, the metal net can be attached to the spiral frame 1 b using bolts 9. Other conventional attachment methods can alternatively be used.

[0058] Fig. 2B shows an exemplary method of attaching the filter fiber 8a to the spiral shaped frame 1 b. Fig. 2B shows a metal disk or blade panel 8 having a large number of fine holes (e.g., drilled holes) with metallic and synthetic fibers 8a mounted in the holes, forming a filter panel. Because the rear side of the metal disk 8 is not smooth due to the metallic and synthetic fibers installed in the disk holes, glue cannot be used, therefore, a gap adjusting panel 10 is installed, and at the same time glue can be used to attach the magnet sheet attachment panel 1 1 and the magnet sheet 12. The magnet sheet 12 will stick to the spiral shaped frame 1 b freely to become a part of the structure. Fig. 2C shows a partial side view of the completed filter with the filter fibers 8a mounted in metal disk 8. It shows that some very fine particles 7 from exhaust gas are stuck to the filter fibers 8a. Fig. 2D shows a perspective view of a portion of a complete filter panel with gap adjusting panel, magnet sheet attachment panel 11 and magnet sheet 12. It should be recognized that while the illustrated construction is advantageous, other methods for connecting the filter panel to the spiral frame could also be used.

[0059] Fig. 3 shows a cutaway side view of a completed exhaust gas filter with filter tank A. A spiral shaped filter unit with the filter fiber 8b attaching to the spiral shaped frame is mounted in a housing tank. Carrier bearings 4a and 4b are installed at each end of the shaft 4c, and a drive pulley 5 is installed at the end of the shaft 4c also.

[0060] Motor 16, belt 17, and pulley 5 rotate the shaft 4c, e.g., at about 500 rpm. The exhaust gas to be cleaned will be fed from exhaust gas inlet connection pipe 15a, will flow through the fiber filter, and the fine particles will be trapped into the filter fibers. The cleaned exhaust gas will be then fed through the exhaust gas outlet connection pipe 15b to the second device in the system.

[0061] Washing water 13a is fed by the cleaning water pipe 13b to the washing nozzles 14. A waste water outflow pipe 21 is installed at the bottom of the tank A. Waste water outflow pipe 21 will get rid of the water used to wash the tank A. The exhaust gas inlet connection pipe 15a will be connected to the CO2 source, e.g. exhaust gas emitting factory or power plant.

[0062] Based on the measurement performed at the exhaust gas outlet connection pipe 15b, the spiral shaped fiber filter devise will only filter the fine particles from the exhaust gas (e.g., from coal) and does not decompose the CO2 gas. The second major component of the systems, the CO2 decomposition and separation device 41 (Fig. 8) will decompose and separate the CO2 gas into carbon and oxygen.

[0063] Fig. 4A shows filter tank A with the rear cover 18b (see Fig. 4C) removed. The front cover 18a (see Fig. 5) and the rear cover 18b are installed to the cover installation flange surfaces 23 on each end. The washed out waste 22 shown in Fig. 4 can be taken out through the inspection doors 19 on both tank A and tank B shown in Fig. 5 and 6. Fig.4B shows a side cutoff view of the spiral shaped frame fiber filter assembly, essentially as illustrated in Fig. 2C. Fig 4C shows a side view of the rear cover 18b, with exhaust gas outlet connection pipe 15b, carrier bearing and mounting for carrier bearing 4b.

[0064] Fig. 5 shows the completed exhaust gas filter device using the spiral shaped frame fiber filter (item 40 in Fig. 8). In this embodiment, there are two filter tanks, tank A and tank B which may be essentially identical, connected in parallel. A timer switch can be installed on the control box 50 to switch the flow of exhaust gas from tank A to tank B and vise versa at a preset time period.

[0065] Two exhaust gas switching valves and air cylinders 15c and 15d are installed, one at the exhaust gas inlet side 15a and one at exhaust gas outlet side 15b, to control the flow of the exhaust gas. After a period of operation, one of the tank filters will be full of fine particles and the exhaust gas flow can become very slow due to the accumulation of fine particles stuck on that fiber filter. Thus, at a set time, the timer switch will trigger the exhaust gas switching valve and air cylinders 15c and 15d, and they will switch the exhaust gas flow from one tank to the other tank, isolating one of the tanks. At this time, the isolated tank filter will be washed and the exhaust gas will be directed to go through the other tank.

[0066] Fig. 6 is a side view of the exhaust gas filter device 40 using the spiral shaped frame fiber filter. Two inspection doors 19 with an inspection door handle 20 are shown. Both Tank A and tank B have these inspection doors.

B. CO2 decomposition and separation device

[0067] As previously indicated, the filtered exhaust gas from filter device 40 is directed to CO2 decomposition and separation device 41. This CO2 decomposition and separation device is described in Niioka, US patent applications 12/072,059, and 12/188,681 , both of which are incorporated herein by reference in their entireties, including drawings.

[0068] This conversion and separation device breaks the carbon oxygen bonds in carbon dioxide (CO₂) as well as in some other air pollutants. The process results in separate particulate carbon (e.g., as graphite) and oxygen gas. The device overcomes current major technical challenges in reducing point source and/or ambient CO₂ concentrations.

[0069] The CO₂ conversion device is a generally closed device (except for suitable inlet and outlet connections) which includes two key components:

A CO₂ conversion chamber;

A graphite-oxygen separation chamber. [0070] As is readily recognized, the device will also include components for gas and liquid handling. Such components can vary depending on the design and application for a particular system. Generally there will be a gas delivery network which includes a CO₂ gas source (e.g., from an exhaust gas particle filter in the present invention) and a series of distribution tubing and control components, e.g., tubing (often coated with a relatively non-reactive material such as Teflon®), valves, pressure regulators (e.g., that introduce, circulate, regulate and maintain pressure of CO₂ and O_{2 at} desired levels in the system) and the like.

[0071] Likewise there will generally be a corresponding liquid handling network which includes components for storing, circulating, and distributing liquids in the devices, including, for example, tanks, pipes, valves, pressure gauges that introduce, circulate, regulate, and maintain pressure of electrolyte solution and a mixture (which may be in a colloid) of CO₂ and O₂ at desired levels in the device.

[0072] The gas and liquid handling will usually be driven by a set of electrical and/or electromechanical devices (motors, pumps, pulleys, belts, .etc) that powers the CO₂ conversion device at desired speeds and pressures.

[0073] To convert CO₂ to graphite and oxygen under ambient condition, a gas with a high concentration of CO₂ (e.g., filter coal-fired plant exhaust gas) and electrolyte solution described herein are introduced by their respective delivery systems at desired levels to a pipe or the first of a set of pipes, e.g., 3 pipes, in series that are housed in the CO₂ conversion chamber. Typically the gas and electrolyte solution are introduced separately but in coordinated fashion, e.g., simultaneously. To ensure adequate mixing and interaction between CO₂ and electrolyte solution in these inductive pipes, each pipe is constructed with mixer, e.g., a shaft with mixing projections such as wings fixed to the shaft and arranged so that the shaft can be spun at high speed. In particular embodiments, the shaft has spiral shaped wings (e.g., 5 wings) welded or otherwise fixed to the shaft. Rotation of the shaft at high speed is believed to induce magnetism inside the pipes. When acidic CO₂ is mixed with alkaline electrolyte solution under such high speed mixing conditions, a filmy, gelatinous substance appears in the CO₂ conversion chamber. While it is possible to design a device such that one or more of the pipes rotate (either instead of the shaft or in addition to the shaft such as in a counter rotating manner), in most cases it is simpler or more desirable to just rotate the shaft.

[0074] This jelly, filmy, gelatinous colloid is then directed to a graphite-oxygen separation chamber. A major component of the graphite-oxygen separation chamber is a filter. An advantageous configuration includes a hollow, cylindrical filter drum perforated with filters, e.g., tubular filters. For example, an exemplary filter drum is made of layers of synthetic silicon resin and perforated with tubular filers (182 such tubular filters in one case). In that example, each tubular filter is 35mm in length, 15mm in outside diameter with 10mm inside diameter at the top, and 10 mm in outside diameter and 5mm inside diameter at the bottom. Each tubular filter is tightly packed with fiberglass string roll at the top and loose fiberglass fibers at the bottom.

[0075] When the filter drum is spun at centrifuge speed inside the graphite- oxygen separation chamber, fresh electrolyte solution is injected to the center of the filter drum to create electrostatic induction that separates graphite from oxygen in the jelly like, filmy substance.

[0076] Under this condition, two reactions follow. First, graphite is attracted to loose fibers dangling from the bottom of tubular filters and is eventually washed and/or dislodged by electrolyte solution. Second, oxygen and un-processed CO₂ passes through the tubular filters that are tightly packed with fiber string roll.

[0077] Excessively high pressure created by introducing the jelly like substance to and/or spinning the filter drum in the graphite-oxygen separation chamber at centrifuge speed is prevented and managed by installing a network of electromagnetic valves e.g., solenoid valves), liquid discharge nozzles, and gas discharge nozzles in the system. Activation of electromagnetic valves and liquid relief nozzle allows 1 ) graphite as well as fresh and spent electrolyte solution to be collected at electrolyte solution tank and 2) gases, such as oxygen and unprocessed CO₂, to flow to oxygen tank. [0078] Conversion of CO₂ to graphite and oxygen under ambient condition is thus achieved.

[0079] Embodiments of a method and device for converting CO2 to carbon particles and oxygen under ambient condition will be understood more fully from the description given below and from the accompanying drawings of embodiments, which, however, should not be taken to limit the method and system to a specific embodiment, but are for explanation and understanding only. It will be recognized that variations can be made to the design within the scope of the invention.

2. Design and Setup of CO2 Conversion chamber

[0081] Fig. 1 depicts the front view of an example of a fully integrated CO₂ conversion device. In the description below, the particular design, including dimensions, materials, numbers of particular components, and other characteristics of the device should be understood to be illustrative and not limiting.

[0082] The device includes a CO₂ conversion chamber 1 and a graphite-oxygen separation chamber 2. To begin converting CO₂ to graphite and oxygen, CO₂ gas and electrolyte solution is injected separately but simultaneously to chamber 1 from a CO₂ source, e.g., cylinder 3, and an electrolyte solution tank 4a through their delivery systems at desired levels. After conversion, the colloid of CO₂ and electrolyte solution is directed to graphite-oxygen separation chamber 2 via two connecting pipes 6a and 6b.

[0083] In this exemplary device, electrolyte solution storage tank 4a is made of SUS 304 stainless steel. Its size is 590mm in diameter, 900mm in height and volume of about 200 liters. The size of the electrolyte auxiliary electrolyte storage tank 4b is 490mm in diameter and 600mm in height and the volume is about 120 liters. It is made of SUS 304 stainless steel. The size of the oxygen collection tank 5 in Fig. 5 is 1200mm in outside diameter and 1300mm in height and is made of steel with the tank interior coated with epoxy resin.

[0084] There are four additional illustrations that provide overview of the CO₂ conversion device: Fig. 2 illustrates rear view of the CO₂ conversion device which sits on stand 12. Fig. 12 (bottom left) Rear view of the CO₂ conversion device. Fig. 12 (top) Top view of the CO₂ conversion device. Fig. 12 (bottom right) Side view of the CO₂ conversion device

[0085] Fig. 3 presents partial sectional view of the CO₂ conversion chamber 1 and graphite-oxygen separation chamber 2. The detailed design of filter drum 18a in chamber 2 is illustrated in Fig. 4A and Fig. 4B which is discussed in sections III and IV below. The size of the CO₂ conversion chamber 1 is 1 ,600 mm in length and 600 mm in diameter. The size of cover 13a is 300mm in width and 600 mm in inside diameter and both covers are made of plastic material (Fig. 6B, bottom).

[0086] Inside the CO₂ conversion chamber 1 , there are three pipes 29a, 29b, 29c made of SUS-304 material (Fig. 5 and Fig. 6A). These pipes are specially designed, interconnected, and in series (29a and 29b are connected by 28a; 29b and 29c are connected by 28b) to ensure continuous mixing of CO₂ and electrolyte solution in the pipes. Five spiral shaped wings similar to that of 26a are welded to shafts 31a, 31 b and 31c, respectively using argon gas welding process. The wings serve to enhance mixing and interaction of CO₂ with electrolyte solution in each pipe. Each set of five wings is labeled 26a, 26b, 26c, respectively in Fig. 5.

[0087] The size of pipe 29a, 29b, and 29c is 1 ,200 mm in length, 145 mm in outside diameter, 3.0 mm in thickness and make of SUS 304 stainless steel. Shaft 31a, 31 b, 31c is installed in the center of pipe 29a, 29b, and 29c, respectively (Fig. 5). Supplemental parts 30 are installed to shaft 31 to ease its wearing (Fig. 6B, top). The size of shaft 31a, 31 b, and 31c is 1500mm in length and 25mm in diameter and is made of SUS-304 material. The size of the rotating electrode spiral shaped wings 26a, 26b, and 26c is made of SUS-304 material and 150 mm in length and 100mm in outside diameter (Fig. 5).

[0088] A cap 32 with a 28mm hole as shown in Fig. 6A is installed on each end of a pipe so that shafts 31a, 31 b, 31c can be extruded (a total of six caps on three pipes). Each cap is made and installed in such a way that CO₂ gas or electrolyte solution would not leak from the end of a pipe. Blind flanges 33a, packing 33b, shaft lineup flanges 33d with three 28mm holes, and flange 33c with bolt holes 25 are constructed to support installation of three shafts 31a, 31 b, and 31c to the CO₂ conversion chamber 1 (Fig. 6B, top). Each end of CO₂ conversion chamber 1 is capped with a cover 13a or 13b and equipped with a drainage pipe 13c or 13d, respectively (Fig. 6B, top). Six bearings 16a and other parts are designed and installed as shown in Fig. 8 to shafts 31a, 31 b, and 31c to provide smooth rotation.

[0089] An electrical motor 7a with pulley 7b and belt 7c provide rotating power to the shaft in pipes 29a, 29b, and 29c which quickly become inductive when CO₂ and electrolyte solution inside are spun at high speed (Fig. 6A).

[0090] Shaft 31 is installed in the center of sleeve 34, and shaft 31 is assembled with a gland packing 36, washer 37, spring 38, sleeve cap 39, bearing attachment bracket 40, shield packing 33b, bolts 35a, 35b, and bearing 16a. Rotation of shaft 31 is provided by an electric motor 7d (Fig. 9).

[0091] A ceramic coating is applied to shaft 31 to slow down corrosion and wear of shaft 31. Due to extreme corrosive conditions in the CO₂ conversion chamber, average life cycle of shaft 31 without ceramic coating is only about 50 hours. This results in frequent change and service of shaft 31 as well as long periods of down time of the CO₂ conversion device.

[0092] Improvements are made to shaft 31 and its related components with a key 43 to prevent unauthorized service or tempering. First, a slot 42V is made on the edge of supplemental part 42P for attaching extraction tool. 42P is then inserted into shaft 31. Another supplemental part 41 P is installed on the outside of part 42P (Fig. 7). A ceramic coating is applied to surfaces of shaft 31 , 41 P and 42P to a thickness of about 50 micrometer. Other thickness may also be selected depending on the particular application, e.g., about 20 to 50, 30 to 60, 40-70, or 50 to 100 micrometer. The material selected for the ceramic coating in this example is chromium oxide applied with plasma spraying equipment. The size for the supplemental part 42P is 50mm outside diameter and 150mm in length and made of SUS-304 material and the size for supplemental part 41 P is 130 mm in length and 51 mm in outside diameter and also made of SUS-304 material. 42 is a supplemental part viewed from left side (Fig. 7).

[0093] With these improvements in place, the life cycle of shaft 31 has increased by about 100 times to 5,000 hours and shaft 31 and its associated components as those depicted in Fig. 7, Fig. 8, and Fig. 9 can now be readily retrieved, serviced and replaced with less time and effort. Fig. 10 illustrates how extraction tool 42z can be used to remove supplemental parts. A technician can easily use handle 42y to extract supplemental parts following the direction shown in 42u.

3. Operations of CO2 Conversion chamber

[0094] Electrolyte solution from tank 4a is pumped by pump 8a to CO₂ conversion chamber 1 while CO₂ from cylinder 3 is piped to CO₂ conversion chamber 1 via Teflon tubing 10 at its desired level by a pressure regulator 11c (Fig. 1 ). Rotating speed of pump 8a is determined by concentration of CO₂ in the chamber so that operator can control optimum mixing of CO₂ with electrolyte solution in pipes 29a, 29b and 29c. For example, when 99.7% CO₂ is used, the motor speed that controls the flow rate of the electrolyte solution is set at 1 ,900 rpm. Excessive electrolyte solution is directed to electrolyte solution storage tank 4a via overflow pipes 10b and 10c.

[0095] Specifically, electrolyte solution as described in herein is powered by pump 8a in the direction as shown in 28w to pipe 29a through nozzle 4c located at the center of pipe 29a (Fig. 5). CO₂ is fed simultaneously but separately in the direction as shown in 28g to pipe 29a through nozzle 10a located also in the center of pipe 29a. As soon as the desired pressure for CO₂ and electrolyte solution is reached, power is then switched on to rotate the shafts in pipes 29a, 29b, and 29c to make sure CO₂ and electrolyte solution freely flow past spiral shaped wings 26a, 26b, 26c, thus enhance mixing interaction of CO₂ and electrolyte solution in the pipes.

[0096] Pipes 29a, 29b, and 29c quickly become inductive when CO₂ and electrolyte solution inside are spun at high speed (Fig. 6A). In other words, when a colloid of CO₂ and electrolyte solution is mixed and treated this way, friction occurs in the vicinity of rotating spiral shaped wings due to constant movement and contact between electrolyte solution and edge of spiral shaped wings. An electrical field is generated from impulse and oscillation, and pipes 29a, 29b, 29c become inductive.

[0097] It is theorized that under this environment, a majority of bipolar molecules in the electrolyte solution break down, generate cations and anions, and release exothermic energy that, under inductive condition, is sufficient to convert CO₂ to graphite and O₂. Hence the conversion of CO₂ to graphite and oxygen is successfully accomplished.

4. Design and Setup of Graphite-Oxygen Separation Chamber [0098] When acidic CO₂ is mixed with alkaline electrolyte solution in pipes 29a, 29b, and 29c in which shafts are spun at high speed, a filmy, gelatinous substance appears in these inductive pipes. This substance consisting of graphite, oxygen, electrolyte solution and un-processed CO₂ eventually reaches nozzle 27, which in turn injects this jelly, filmy substance to the interior of CO₂ conversion chamber 1 (Fig. 5). The filmy substance is then directed to graphite-oxygen separation chamber 2 via connecting pipes 6a and 6b (Fig. 4B). The size of the connecting pipes 6a and 6b in this exemplary device is 400mm in length and 120mm in outer diameter. These two pipes are installed horizontally to the right and left side of the graphite-oxygen separation chamber 2 (Fig. 4B).

[0099] A cross section of the filter drum and graphite-oxygen separator 23a is shown in Fig. 4B. In this exemplary device, the main component inside the graphite-oxygen separation chamber 2 is a hollow, cylindrical rotation drum 18a. The filter drum assembly 21a in this case is made of layers of synthetic silicon resin 45a glued together with silicon resin adhesive 45b (Fig. 11 , bottom right) and perforated with a large number of tubular filters 47 (Fig. 11 , top right). In an exemplary device, one hundred and eighty two (182) tubular filters were used. Each layer of silicon resin is made of synthetic fibers 44 (Fig. 11 , bottom right). The size of rotation drum 18a in the exemplary device is 1 ,200mm in length and the central drum diameter is 500 mm. It takes approximately 1 ,500mm by 500mm with 10 mm thickness of layers of synthetic silicon resin sandwich to construct a cylindrical, hollow rotating filter drum 21a as seen in Fig. 4A (right bottom). The synthetic silicon resin sandwich is constructed as shown in Fig. 11 (right bottom) A synthetic fiber 44, a synthetic-resin silicon layer 45a, and a synthetic silicon adhesive 45b are stacked together with a pile cut fiber 46 to form the synthetic silicon resin sandwich. The filter drum is installed inside the rotation drum 18a (Fig. 4A, top) and can be serviced or replaced through door 9 (Figs. 1 , 2). The size of plastic tubular filter 47 in the exemplary device is 35mm in length, 15mm in outside diameter with 10mm inside diameter at the top, and 10 mm in outside diameter with 5mm inside diameter at bottom.

[00100] The rotation drum 18a is firmly positioned and framed by two casings: upper half casing 2a and lower half casing 2b. The contact surface between the rotation drum and connecting pipe 19 connects the outer body 40a and the cap 20 to prevent gas leakage (Fig. 4B). The filter drum is constructed by shaping synthetic silicon resin sandwich into circular form (Fig. 4A, bottom right). One hundred and eighty-two 14 mm holes are drilled through 3 layers of silicon resin. Plastic tubular filter 47 that packed with fiber string roll is then forcefully inserted to each hole. Synthetic silicon resin adhesive is used to seal surroundings of each tubular filter 47 (Fig. 4A, bottom right) to prevent gas leak 55. (Fig. 11 )

[00101] The length of the upper casing 2a and lower casing 2b for filter drum 18a is 1400mm and the largest outside diameter is 600 mm (Fig. 4B).

[00102] Construction of tubular filter 47 is as follows. Fiberglass fibers are first made into strings 52 and then rolled tightly into a filter string roll 50 (Fig. 11 , bottom left). Tightly rolled fiber roll 50 is then forcefully inserted from the top into tubular filter 47 (Fig. 11 , top left). Due to a larger inside diameter at the top and smaller ID at bottom portion of tubular filter 47, (Fig. 11 , top left), tightly packed fiber string roll 50 will fit tightly inside the full length of tubular filter while the bottom portion 48 of the tubular filter is dangling with loose fiberglass fibers 51 (Fig. 11 , top left). Black dots in Fig. 11 , top left denotes graphite particles. Fig. 11 (top right) shows a top view of a small section of the filter drum.

[00103] Two shield packings 15a and 15b (Fig. 4A, top) and two bearings 16a and 16b are installed on the shaft 17a and connection shaft 17b of the filter drum 18a to provide a smooth rotation (Fig. 4B). Pipe 40a serves as bearing receptacle to link with connection pipes 6a and 6b (Fig. 4B). An electrical motor 7a with pulley 7b and belt 7c provides the rotating power to shaft 17a which in turn rotates filter drum 18a at centrifuge speed and causes the filmy substance from the CO₂ conversion chamber 1 to flow into graphite-oxygen separation chamber 2 via connecting pipes 6a and 6b (Fig. 4B).

5. Operations of Graphite-Oxygen Separation Chamber

[00104] When filter drum 18a is spun at centrifuge speed inside the graphite- oxygen separation chamber 2, fresh electrolyte solution is injected via pipe 8b to the center of the filter drum. Such operations make the filter drum 21a inductive and facilitate separation of graphite from oxygen. (Figs. 4A, top and bottom right) Electrolyte solution released from jet/nozzle 21 b (which is installed at the end of pipe 8b) is used to wash and dislodge graphite from loose fibers and to prevent the tubular filters from clogging (Fig. 4A, top). Cap 20 is installed at each end of the filter drum assembly to prevent leakage of liquid and gas (Fig. 4A, top). Furthermore, because after long hours of operation the tubular filters may become clogged with graphite, a timer is preferably installed to control the washing operation.

[00105] With reference again to jelly, filmy substance 53 (Fig. 4A, bottom left) coming out of the CO₂ conversion chamber 1 , this substance is redirected following the direction as shown in 28c (Fig. 5) to the filter drum 18a in the graphite-oxygen separation chamber 2 via connecting pipes 6a and 6b (Fig. 3). At this time, filter drum is spun at centrifuge speed and fresh electrolyte solution is injected from pipe 8b to the center of filter drum (Fig. 4B). Just like what happens in the CO₂ conversion chamber, high speed spinning of filter drum that contains a colloid of graphite, oxygen, un-processed CO₂ and electrolyte solution made the filter drum inductive. Due to the high rotation speed and more electrolyte solution, the electrostatic induction created in the filter drum is typically stronger than the one in the CO₂ conversion chamber 1.

[00106] As a result, graphite in the colloid is attracted and migrates to loose fibers of tubular filters 47 (Fig. 4A, bottom left). Graphite is washed off from tubular filters in graphite-oxygen separation chamber 2 with electrolyte solution. The electrolyte solution that contains graphite eventually is fed to electrolyte solution storage tank 4a. Introduction of jelly, filmy substance 53 from CO₂ conversion chamber 1 to graphite-oxygen separation chamber 2 via connecting pipes 6a and 6b and/or spinning of filter drum 18a at centrifuge speed creates high pressure in the device. To prevent excessive build-up of high pressure in the device, an electronically controlled network of magnet for solenoid valve 2c, electromagnetic valves 23b, liquid discharge nozzle 21c, and gas discharge nozzle 22 is installed to adjust gas pressure (Fig. 4B). [00107] Deactivation or closure of 2c and 23b stops the flow of jelly, filmy substance to graphite-oxygen separation chamber 2. Activation of both valves allows graphite along with spent and fresh electrolyte solution plus trace of O₂ and un-processed CO₂ to be piped to electrolyte solution storage tank 4a via liquid discharge nozzle 21c. Activation of both 2c and 23b also allows oxygen 49 (which has passed through tubular filters 47, see Fig. 11 , top left) along with unprocessed CO₂ plus trace of electrolyte solution to be piped to collection tank 5 (Fig. 1) via gas discharge nozzle 22 (Fig. 4B) and Teflon tubing 11a and valve 11 b (Fig. 1). Contents of tank 5 can be drained via pipe 24 (Fig. 2).

C. Design and set up of a carbon filter device using a declined angle approach and a carbon collection device

[00108] As indicated above, electrolyte used in the CO2 decomposition and separation device will quickly load with particulate carbon and become ineffective unless the carbon is removed. Such removal can be accomplished using an electrolyte filter. Advantageously, the filter will effectively clean the electrolyte with low energy consumption. A suitable electrolyte filter device corresponding to item 42 in Fig. 8 is illustrated in Fig. 7.

[00109] Thus, Fig. 7 shows perspective and side views of a declined angle carbon fiber filter device 42, used to collect carbon from the electrolyte. The declined angle carbon filter has an outer case 26, with conveyer rolls 28b installed in it. A carbon collection fiber filter 24 is installed on the conveyer belt 25. In the design shown, six pieces of carbon collection fiber filter 24 are installed. A pile cut texture fiber is used in this design. An internal roll installation motor 37 is used to drive the conveyer roll 28b. The output power for the motor in an exemplary device is 3.5 horsepower and it rotates at 50 rpm. The driving motor and pump are controlled from control box 50. This control box 50 can be installed on the CO2 decomposition and separation device 41. All driving motors and pumps are preferably automatically controlled.

[00110] For the exemplary system, the control box 50 has six control switches and a timer switch installed on it. As depicted in Fig. 9, they are the CO2 decomposition and separation devise motor control switch 44, the CO2 decomposition and separation device blower control switch 45, the CO2 decomposition and separation device pump control switch 46, the exhaust gas filter device using the spiral shaped frame fiber filter motor control switch 47, the carbon filter device using the declined angle approach pump control switch 48, the carbon collection device to collect carbon from the electrolyte motor control switch 49, and a timer switch 51. The conveyer motor will rotate based on the timer switch 51.

[00111] As shown in Fig. 7, the electrolyte is pumped to the electrolyte collection box 29 from the electrolyte tank 4a of the CO2 decomposition and separation device 41 and through the electrolyte inlet pipe 32b. The electrolyte collection box declined angle adjustment devise 30 will adjust the flow of the electrolyte.

[00112] The electrolyte solution will flow from top to bottom of the carbon collection fiber filter 24. The carbon is in the form of very fine particle resulting from the decomposition of the CO2, and will penetrate into the center of the filter, and thus the carbon is separated from the electrolyte solution. By this method, the carbon is separated from the electrolyte solution and sticks to the fiber filter.

[00113] The carbon collection fiber filter 24 will be washed by the washing nozzle 27 with the washing pressure provided by the filter washing nozzle pump 33.

[00114] The washed carbon can go through a separator, e.g., centrifugal separator 31 , to separate the carbon from the water.

[00115] Using the electrolyte immersed filter tank 35, the filter washing pump 33 can continuously operate.

[00116] In summary, Fig. 1 , Fig. 2, Fig 3, Fig. 4, Fig. 5, and Fig. 6 describe an effective device to filter fine particles from the exhaust gas.

[00117] Fig. 7 describes a carbon filter device using a declined angle with fiber filter to allow the electrolyte to flow from top to bottom through the filter, allowing filtration with comparatively low electrical power usage.
