Description

{CARBON CAPTURE SYSTEM USING EXHAUST GAS DISCHARGE PRESSURE}

The present disclosure relates to a carbon capture system utilizing exhaust gas discharge pressure.

In general, large-scale tower-scale facilities such as factories and ships are operated to capture carbon. Since these facilities are subject to spatial constraints, it is difficult to apply them to various carbon generating devices, and it is realistically impossible to reduce the cost of installing and maintaining existing large-scale facilities. Therefore, RPB systems are also applied to solve these problems in the past.

The existing RPB (Rotating Packed Bed) system captures carbon by bringing the absorbent and exhaust gas into contact with each other through high-speed centrifugal force, and has the advantage of efficiently processing high-concentration and high-temperature exhaust gas. However, this method has the disadvantage of high energy consumption because it relies on the high-speed rotation of the motor. In the long term, this high energy consumption can increase operating costs and partially hinder its effectiveness as an eco-friendly technology.

In addition, RPB systems require complex configurations of motors and related parts to maintain high-speed rotation. This results in maintenance and parts replacement costs, and in particular, parts may wear out quickly due to high-speed rotation, which may reduce operational stability. In addition, high-speed rotation motors are prone to generating noise and vibration, which may limit their application in certain industrial environments and may also have a negative impact on the quality of the work environment. These characteristics also limit the miniaturization of the system, and simpler and more efficient alternative technologies are required.

The above-described information disclosed in the background technology of this invention is only intended to improve understanding of the background of the present invention and therefore may include information that does not constitute prior art.

The present disclosure aims to create an environment in which an absorbent and carbon react by generating rotational force using the exhaust pressure of the exhaust gas without relying on the rotational force of a motor in the process of capturing carbon from exhaust gas.

FIG. 1 and FIG. 2 are exploded perspective views of a capture device (10) according to one embodiment of the present disclosure. Referring to FIG. 1 and FIG. 2, according to one embodiment of the present disclosure, a carbon capture system using exhaust gas discharge pressure (hereinafter, capture device (10)) may include a housing (100) and an absorption unit (200). Here, the housing (100) may be connected to a generation unit (20) that generates exhaust gas and may be configured to allow exhaust gas to flow in. In addition, the absorption unit (200) may be positioned so as to be freely rotatable inside the housing (100). Specifically, the absorption unit (200) may be rotated within a predetermined rotational speed range by the exhaust gas discharge pressure.

In addition, the capture device (10) may further include a fluid transport pipe (300). The fluid transport pipe (300) may guide the transport of exhaust gas and the transport of the absorbent. The fluid transport pipe (300) will be described in more detail with reference to FIGS. 7 and 8 below.

Meanwhile, the fluid transport pipe (300) may be connected to the housing (100), and the absorption unit (200) may be provided inside the housing (100). The housing (100) and the absorption unit (200) may be arranged coaxially. Specifically, the housing (100) may include a main housing (110) and a first cover (101) and a second cover (102) arranged on both sides of the main housing (110). The first cover (101) may be provided so that the main housing (110) can be kept airtight, and is connected to the absorption unit (200) provided inside the housing (100) by a bearing so that the absorption unit (200) can rotate freely.

Of course, the absorption section (200) is connected to the first cover (101) and the second cover (102) with bearings so that it can rotate freely. However, in the case of the second cover (102), the part that comes into contact with the main housing (110) is connected so as to maintain airtightness, but a part of the fluid transport pipe (300) can be opened so that it can be inserted into the housing (100). Accordingly, the second cover (102) can be connected airtightly with the housing (100) and airtightly with the fluid transport pipe (300) so that the inside of the housing (100) can be communicated with the fluid transport pipe (300). Through this, the exhaust gas inside the housing (100) can also be transferred to the fluid transport pipe (300).

According to one embodiment of the present disclosure, a reaction between exhaust gas and an absorbent is performed in the internal space of the housing (100), so that the absorbent can absorb CO2. The absorbent (200) rotates due to the inflowing exhaust gas, and the absorbent sprayed from the center of the absorbent (200) moves along the surface of the absorbent (200) by centrifugal force, and can react with the exhaust gas during the movement process. By the reaction, CO2 in the exhaust gas can be absorbed by the absorbent and released to the inner wall of the housing (100). The released absorbent can move downward along the inner wall of the housing (100) by its own weight.

FIG. 3 is a schematic diagram showing the transmission of flue gas generated from a generation unit (20) that generates flue gas containing carbon according to one embodiment of the present disclosure to a capture device (10). Referring to FIG. 3, when flue gas is generated by the generation unit (20), the generated gas can be induced to flow into the capture device (10). This can be connected through a predetermined piping structure. Here, the flue gas can be, for example, combustion gas. Accordingly, the generation unit (20) can be an automobile, one of the facilities of a factory, or equipment installed on a ship. Any configuration that generates flue gas containing carbon such as combustion gas can correspond to the generation unit (20) of the embodiment.

Since the configuration that can be the generating unit (20) is diverse, the structure connected to the collecting device (10) is not specified, and it is preferable that it is connected through a structure for inducing gas and that the gas generated through the seal is transmitted to the collecting device (10) without loss of discharge pressure. This may be a structure that is preferable to prevent discharge pressure from being lost, since the present disclosure performs the rotational motion through the discharge pressure of the exhaust gas without a separate motor or the like for the power required for the rotational motion.

In addition, the generation unit (20) may be connected to one collecting device (10), but may also be connected to multiple collecting devices (10) considering the exhaust gas discharge capacity of the generation unit (20) and the processing capacity of the collecting device (10). Depending on the concentration and discharge amount of the exhaust gas, multiple collecting devices (10) may be connected to the generation unit (20) through one or more of a parallel and a series connection method.

FIG. 4 is a perspective view of a capturing device (10) according to one embodiment of the present disclosure. Referring to FIG. 4, a housing (100) may include an inlet that is connected to a generator (20) to maintain a seal so that exhaust gas is introduced, a main housing (110) that is expanded so that the exhaust gas introduced through the inlet can be rotatably flowed, and a discharge pipe (104) that discharges an absorbent reacted with carbon in the exhaust gas to the outside of the main housing (110). Here, the fluid flow may be formed in a direction of supplying exhaust gas (f1) and a direction of discharging an absorbent liquid (f2). Here, the absorbent liquid may be an absorbent that captures CO2 through a reaction between the absorbent provided into the housing (100) and the exhaust gas. Since the absorbent liquid may be in a liquid phase, the absorbent liquid may be in a liquid phase. Therefore, the absorbent liquid may be moved downward by its own weight and may be moved through a discharge pipe (104) that is opened downward at the bottom of the housing (100). Afterwards, the absorbent is re-separated into absorbent and CO2 in a state before reaction, so that the absorbent can be reused, and the CO2 can be liquefied and stored in a storage medium or reused through phase change, etc.

Meanwhile, the reaction between the absorbent and the exhaust gas inside the housing (100) can be more actively performed by the rotational flow formed by the pressure of the exhaust gas flowing into the housing (100). As described above, the absorbent part (200) can be positioned inside the housing (100) so as to be able to freely rotate, and the exhaust gas can be introduced into the housing (100) so that the absorbent part (200) can easily rotate. For example, as illustrated, the exhaust gas can be introduced tangentially into the absorbent part (200) located inside the housing (100) such that it is tangentially connected to the main housing (110) to facilitate rotation.

Meanwhile, in addition to the flue gas supply direction (f1) and the absorbent discharge direction (f2), a residual gas discharge direction (f3) and an absorbent supply direction (f4) may be formed as the flow of fluid. Here, the residual gas refers to gas from which some or all of the CO2 is removed by reacting with the absorbent in the flue gas. Preferably, the purpose may be to capture, for example, 90% or more of the CO2 contained in the flue gas flowing into the housing (100), and in this case, a series-connected capturing device (10) may be operated to reach any desired capture amount.

Meanwhile, the exhaust gas introduced into the housing (100) can be discharged as residual gas through the fluid transport pipe (300) after the reaction. The residual gas can be discharged along the exhaust path (331a), which is a path formed through the exhaust pipe (330), by sequentially passing through the first external pipe (320a) and the second external pipe (320b). The discharged gas can be released into the atmosphere, delivered to a predetermined processing system, or repeatedly introduced into the inlet of another adjacent capturing device (10). That is, as described above, the capturing process can be performed so that the absorbent reacts with the remaining CO2 included in the residual gas by introducing it into an adjacent capturing device (10) connected in series.

Here, the first outer pipe (320a) and the second outer pipe (320b) may be formed integrally, but as illustrated, in order to selectively position the exhaust path (331a), the second outer pipe (320b) connected to the exhaust pipe (330) is provided separately from the first outer pipe (320a) so that they can be assembled together. The first outer pipe (320a) and the second outer pipe (320b) may be connected by the first flange portion (321). The second flange portion (322) may be a connecting means between the second outer pipe (320b) and the inner pipe (340).

FIG. 5 is a drawing showing an absorption unit (200) and a housing (100) housing the absorption unit (200) in a capturing device (10) according to one embodiment of the present disclosure. Referring to FIG. 5, the absorption unit (200) may include blades (211) facing the direction in which exhaust gas flows into the outer periphery. The blades (211) may be fixed to a plate (210). The plates (210) are configured as a pair, and a plurality of plates (210) may be fixed radially between the pair of plates (210).

A space may be provided between a pair of plates (210) in which a reaction unit (220) is positioned. The reaction unit (220) may have a predetermined thickness, and may be formed as a plate (210) type with holes or may be formed of a porous material. Alternatively, it may have a porous structure. In addition, the reaction unit (220) may be extended in a radial direction from the center while having sections such as bends, curves, and planes. This structure may be a structure that can increase the reaction rate by allowing the absorbent to be sprayed from the center of the reaction unit (220) and come into contact with the exhaust gas through the large surface area of the reaction unit (220). Although the illustrated reaction unit (220) is expressed only as having a perforated center, it is obvious that various embodiments described above may be reflected.

Meanwhile, the exhaust gas flowing into the housing (100) can be formed in a circular flow direction (F1) due to the shape of the housing (100). The exhaust gas rotating in the flow direction (F1) can be guided to the blades (211) and flowed between the plates (210) while pushing the blades (211) as the amount of flow increases and rotating the absorbent section (200). The exhaust gas flowing between the plates (210) can be rotated from the outside of the reaction section (220) by the discharge pressure of the exhaust gas and then moved toward the center as the amount of flow increases, and the absorbent can move along the surface of the reaction section (220) radially outward from the center of the reaction section (220). By this movement, the exhaust gas comes into contact with the absorbent and a reaction occurs, so that CO2 contained in the exhaust gas can be absorbed by the absorbent.

FIG. 6 is a cross-sectional view showing the inside of a housing (100) according to one embodiment of the present disclosure. Referring to FIG. 6, the inlet may be connected to the main housing (110) so that the exhaust gas is discharged in a direction parallel to the tangential direction of the absorption unit (200) inside the main housing (110). Here, the tangential direction may be a tangential line that contacts the outer periphery of the plate (210) on the illustrated side. This direction of the inflow of the exhaust gas transmits the exhaust gas discharge pressure to the blade (211) so that the absorption unit (200) can rotate. The continuous inflow of the exhaust gas can fill the housing (100) with the exhaust gas up to the center. That is, the exhaust gas can be filled from the outer side to the center of the absorption unit (200).

On the other hand, the absorbent is sprayed in the spraying direction (S1) from the center of the reaction section (220) through the nozzle (311) formed in the spray head (310) and can be moved radially by centrifugal force on the rotating reaction section (220). Accordingly, the absorbent and the exhaust gas can move in opposite directions and react during the process of intersecting each other.

The absorbent liquid, which is an absorbent that has reacted with CO2 in the exhaust gas, can be discharged to the outside of the housing (100) through the discharge pipe (104). The discharge pipe (104) can be connected to the lower part of the main housing (110). Therefore, when the absorbent liquid moves downward along the inner wall of the housing (100) due to its own weight, it can be discharged through the discharge pipe (104). The discharged absorbent liquid can be separated into the absorbent and CO2, and each can be reused.

In addition, as described above, the absorption section (200) may include a reaction section (220) formed of a porous material or a porous structure. The structure of this reaction section (220) may improve the reaction efficiency by extending the reaction time while delaying the permeation of the fluid in the radial direction. To this end, structures such as bending, curving, and perforation may be provided throughout the entire section extending in the radial direction.

FIG. 7 is a cross-sectional view of a collecting device (10) including a fluid transport pipe (300) according to one embodiment of the present disclosure. Referring to FIG. 7, the fluid transport pipe (300) is configured as a double pipe including an inner pipe (340) and an outer pipe (320; 320a, 320b), and the outer pipe (320; 320a, 320b) is connected to the housing (100) so that exhaust gas flowing into the housing (100) is discharged, and the inner pipe (340) extends from the inside of the outer pipe (320; 320a, 320b) into the inside of the housing (100) so as to spray an absorbent onto the absorbent portion (200). Specifically, the outer tube (320; 320a, 320b) can form an outer passage of the double tube so that the exhaust gas is discharged as residual gas after reacting with the absorbent, and the inner tube (340), which is the inner passage, can be provided to form a passage for providing the absorbent to the housing (100).

The inner tube (340) can supply absorbent through an external supply means and supply it to the inside of the housing (100) through the inner tube (340) at a predetermined pressure. At this time, the absorbent can be sprayed through a spray head (310) that sprays the absorbent into the inside of the housing (100). The spray head (310) includes a plurality of nozzles (311), and a plurality of nozzles (311) can be formed on the outer periphery of the spray head (310) so that the absorbent is sprayed radially.

That is, the fluid transport pipe (300) is connected to the extended end of the inner pipe (340) and extends toward the housing (100), and a spray head (310) can be connected to the extended end. The spray head (310) can spray the absorbent into the reaction section (220), which is a component of the absorption section, through a plurality of nozzles (311). The condition for spraying the absorbent inside the housing (100) may be when the absorption section (200) is rotating. This can be determined by a control section (not shown) based on whether the absorption section (200) is rotating. Of course, the control is not limited to these conditions, and as an example of the control, the reaction section (220) can provide the absorbent through the inner pipe (340) when the absorption section (200) is rotated by exhaust gas.

Meanwhile, the external pipe (320; 320a, 320b) may be provided with a first external pipe (320a) directly connected to the housing (100) and a second external pipe (320b) connected to the first external pipe (320a). Here, the second external pipe (320b) may have an exhaust pipe (330) formed to extend a path through which residual gas is discharged to the outside. The outside through which residual gas is discharged may be the atmosphere, or may be another adjacent capturing device (10) or a device for a predetermined treatment. In other words, the outside may be a device or space through which gas is discharged after being processed in the capturing device (10) of the present invention.

FIG. 8 is a perspective cross-sectional view of a capturing device (10) according to one embodiment of the present disclosure. Referring to FIG. 8, a residual gas discharge direction (f3) and an absorbent supply direction (f4) are indicated. A space formed between an outer tube (320; 320a, 320b) and an inner tube (340) can function as a path through which residual gas is discharged. The fluid flow directions formed in the inner tube (340) and the outer tube (320; 320a, 320b) can be mutually orthogonal. A fluid flow of the inner tube (340) flowing into the housing (100) and a fluid flow of the outer tube (320; 320a, 320b) discharged from the housing (100) can be formed.

Since the direction in which the exhaust gas flows in is parallel to the tangential direction of the housing (100), the velocity of the exhaust gas immediately after the flow is the greatest, so that the exhaust gas can rise from the outside to the inside as it flows into the housing (100). In this process, it can come into contact with and react with the absorbent moving from the inside to the outside. That is, the absorbent moves radially from the center of the housing (100), and the exhaust gas flowing into the housing (100) moves from the radial direction to the center, and the absorbent can absorb CO2 contained in the exhaust gas by contact during the movement path of the absorbent and the exhaust gas.

FIG. 9 is a diagram illustrating a process of capturing carbon from exhaust gas according to one embodiment of the present disclosure. Referring to FIG. 9, exhaust gas generation (S10), exhaust gas introduction (S20), absorbent injection (S30), CO2 absorption (S40), and absorption liquid separation (S50) can be performed sequentially.

The flue gas generation (S10) step means that the flue gas is generated from the generation unit (20). In some cases, the generation unit (20) may be linked to detect the generation of flue gas by the operation of the generation unit (20) and the capture device (10) may be driven. The generation of flue gas is performed so that at least the discharge pressure of the generated flue gas is not lost and can be transmitted to the capture device (10) in a hermetically sealed manner.

In the exhaust gas introduction (S20) step, the exhaust gas delivered from the generation unit (20) may be introduced into the housing (100) to rotate the absorption unit (200). The rotating absorption unit (200) may be rotated at a predetermined rotational speed. For example, when aiming to rotate at 500 RPM, a portion of the exhaust gas may be bypassed or external atmosphere may be additionally supplied to increase the pressure (flow rate) in order to control the rotational speed. A configuration such as a compressor or a blower for this purpose may be selectively applied.

The absorbent injection (S30) step can be performed during the rotation of the absorption unit (200). The absorbent can be directly injected into the reaction unit (220), which is a component of the absorption unit (200), and centrifugal force is generated by the rotation of the reaction unit (220), and the absorbent directly injected onto the surface of the reaction unit (220) by the centrifugal force can move outward along the surface of the reaction unit (220). That is, since the rotation of the absorption unit (200) is generated by the inflow of exhaust gas, contact can occur between the exhaust gas and the absorbent.

In the CO2 absorption (S40) step, the absorbent and the exhaust gas that are in contact with each other react and can move to the outside by the rotation of the absorption unit (200) as a liquid absorbent. The exhaust gas with a relatively low density can move to the inside via the outside as it flows into the housing (100). Therefore, in the absorption liquid separation (S50) step, the absorbent and the absorbent with a relatively high density can move to the outside and move to the discharge pipe (104), and the exhaust gas can move to the external pipe (320; 320a, 320b) that is connected to the central part of the housing (100). The absorption liquid that is moved to the discharge pipe (104) and stored can be separated into CO2 and the absorbent through a predetermined process and each can be reused, etc.

Although the present invention has been described above by means of limited embodiments and drawings, the present invention is not limited thereto, and various modifications and variations are possible by those skilled in the art within the scope of the technical idea of the present invention and the equivalent scope of the patent claims to be described below.
