Technical Field

[0001] The present invention relates to the technical field of carbon dioxide storage, and in particular to a storage device for carbon capture. Background Art

[0002] Currently, carbon capture and storage technology has become one of the core means to address global warming and achieve the goal of carbon neutrality. In industrial emission sources (such as coal-fired power plants, steel mills, chemical plants, etc.), carbon dioxide is often mixed with large particulate impurities (such as dust, metal debris, unburned carbon particles, etc.). These impurities not only significantly reduce the carbon capture efficiency but also pose multiple technical challenges to subsequent transportation, storage, and utilization.

[0003] Therefore, it is necessary to filter the impurities inside carbon dioxide before its recovery and storage. Limited by the structural characteristics of traditional pipeline filtration devices, the adhesion and accumulation of impurities on the surface of the filter screen and the inner wall of the pipeline are prone to form caking deposits. The cleaning of such deposits relies on periodic shutdown and disassembly, and artificial intervention means such as high-pressure water gun flushing, mechanical scraping, or chemical solvent immersion are required, which not only leads to production interruption but also involves high-intensity physical labor and the risk of secondary pollution.

[0023] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following will make a detailed description of the specific embodiments of the present invention with reference to the accompanying drawings of the specification.

[0024] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from the description herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0025] Second, the "one embodiment" or "embodiment" referred to herein means a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The appearances of "in one embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or selectively exclusive embodiments from other embodiments.

[0026] Embodiment 1, referring to Figures 1 to 3 , is the second embodiment of the present invention. The difference from the first embodiment is that it further includes a storage tank 2; the storage tank 2 adopts a multi-layer composite tank structure; a replaceable corrosion-resistant alloy lining such as 316L stainless steel or nickel-based alloy is added to the inner wall of the carbon steel tank body and fixed by mechanical buckles or bolts to isolate CO 2 from direct contact with the tank body.

[0027] Design a double-layer tank body, and fill the interlayer with an inert gas such as nitrogen or a desiccant to absorb the leaked CO 2 and inhibit the infiltration of impurity H 2 O, H 2 S into the main tank body.

[0028] Furthermore, the tank body can be divided into multiple independent compartments separated by partition plates. If a certain section is severely corroded, it can be repaired or replaced separately to avoid overall scrapping; a flow guide plate or a honeycomb structure is arranged inside the tank body to reduce the turbulent impact during the flow of CO 2 and reduce the local corrosion rate.

[0029] Preferably, annular or spiral reinforcing ribs are added to the outer wall of the tank to enhance the overall bending and impact resistance capabilities and disperse the local stress at low temperatures.

[0030] It should be noted that a pressure sensor and a pressure relief valve for detecting the internal pressure value are installed outside the storage tank 2; when the internal pressure of the storage tank 2 reaches a certain value, the internal pressure of the storage tank 2 can be reduced by opening the pressure relief valve; thus effectively avoiding the problem of excessive internal pressure in the storage tank 2.

[0031] Furthermore, the filtering unit 1 is connected to the air inlet of the storage tank 2; the filtering unit 1 includes a support pipe 11, a partition 12 arranged inside the support pipe 11, and a filter element 13 arranged inside the support pipe 11; along the air inlet direction, the filter element 13 is arranged upstream of the partition 12, and the gas flows through the filter element 13 in sequence and enters the inside of the partition 12; the partition 12 includes an air inlet pipe 121 flowing unidirectionally along the air inlet direction and a countercurrent pipe 122 flowing in the opposite direction to the flow direction of the air inlet pipe 121; the gas reversely flushes the filter element 13 through the countercurrent pipe 122, thereby realizing the cleaning of the filter element 13.

[0032] It should be noted that the support pipe 11 and the storage tank 2 are butt-jointed via a flange structure, and the gap between the support pipe 11 and the storage tank 2 is compressed and fixed by bolts; and the end of the support pipe 11 close to the partition 12 is connected to the storage tank 2.

[0033] The outer diameter of the partition 12 is matched with the inner diameter of the supporting pipe 11; the partition 12 is fixed to the supporting pipe 11 by bolt connection or welding; the partition 12 includes two channels with opposite passages, the passage direction of the air intake pipe 121 is along the direction in which the gas enters the storage tank 2; and the countercurrent pipe 122 forms a passage along the opposite direction.

[0034] The filter element 13 is arranged on one side of the partition 12, and the filter element 13 is located at the upstream position where the carbon dioxide enters the storage tank 2. Before entering the storage tank 2, it first needs to pass through the filter element 13 and then enter the air intake pipe 121, and finally enter the storage tank 2 through the air intake pipe 121.

[0035] Furthermore, the filter element 13 can preferably be a metal sintered filter; it is sintered from stainless steel, nickel-based alloy or titanium alloy, and has high mechanical strength, high pressure resistance and high temperature resistance; its rigid structure can withstand high-pressure reverse airflow and effectively remove the filter cake layer.

[0036] The counterflow pipe 122 flows in the opposite direction to the air inlet pipe 121. A one-way valve and a pressure valve may be installed inside the counterflow pipe 122 to effectively prevent the gas from flowing in the opposite direction. When the pressure inside the storage tank 2 reaches a threshold, the pressure valve inside the counterflow pipe 122 opens, causing the high-pressure carbon dioxide inside the storage tank 2 to flow in the opposite direction. The high-pressure carbon dioxide will reversely impact the impurities remaining on the surface of the filter element 13, causing the impurities to detach from the pores of the filter element 13, and then open the slag discharge port to discharge the high-pressure carbon dioxide and impurities from the support pipe 11 together. When the pressure inside the storage tank 2 is lower than the threshold of the pressure valve inside the counterflow pipe 122, the pressure valve pipe wall forms a relatively avoided space inside the storage tank 2.

[0037] In summary, through the backwash design, the impurities on the surface of the filter element 13 can be quickly cleaned after the storage of carbon dioxide is completed once, effectively avoiding the accumulation of impurities and causing the filtering performance of the filter to decrease; the efficient working characteristics of the filter element can be always maintained during multiple storages; at the same time, the impurities can be quickly cleaned in conjunction with the slag discharge pipe to achieve the effect of regular cleaning.

[0038] Example 2, reference Figures 1 to 5, which is the first embodiment of the present invention. This embodiment provides a storage device for carbon capture, which includes a one-way valve installed inside the intake pipe 121, thereby forming a one-way passage for gas flow; a pressure valve is installed inside the countercurrent pipe 122. When the internal gas pressure of the storage tank 2 reaches a threshold value, the pressure valve inside the countercurrent pipe 122 will open and form a reverse flow passage.

[0039] In this embodiment, a one-way valve is installed inside the intake pipe 121. Through the one-way valve, the direction of gas flow can be controlled, effectively avoiding reverse gas flow.

[0040] A one-way valve is provided inside the countercurrent pipe 122, and a pressure valve is also installed. Through the cooperation between the two valves, it can be controlled that the carbon dioxide flowing in the reverse direction needs to reach a certain pressure value to achieve reverse flow.

[0041] During the actual use process, when the pressure inside the storage tank 2 reaches a certain value, the pressure valve inside the countercurrent pipe 122 will open. At the same time, through the one-way valve inside the countercurrent pipe 122, the storage tank - filter element controls the flow direction of carbon dioxide to the filter element 13, and the high-pressure carbon dioxide will wash the pores of the filter element 13; thus achieving the purpose of cleaning the filter element 13.

[0042] Furthermore, the filter element 13 is inclined and arranged inside the pipe, and an angle α is formed between the normal line of its cross-section and the axis of the support pipe 11, constituting a non-vertical installation structure.

[0043] In this embodiment, the filter element 13 is inclined and arranged inside the support pipe 11; the inner wall of the support pipe 11 closer to the ground during installation is the bottom inner wall; the angle between the bottom inner wall and the cross-section of 13 is an acute angle. When the filter screen blocks impurities, under the action of gravity, the impurities will settle on the bottom inner wall of the support pipe 11; and are discharged from the inside of the pipe through the slag discharge pipe.

[0044] Furthermore, the inclined filter screen forms an asymmetric angle with the air flow direction, forcing the particulate matter to impact the filter screen under the action of inertia and then slide down along the inclined plane, reducing the secondary suspension of impurities; at the same time, the inclined structure can guide the air flow to form a laminar flow path, reduce the eddy current area, and reduce the random deposition of impurities on the back of the filter screen, which is more convenient for centralized and unified treatment of impurities.

[0045] Furthermore, a guiding member 14 is provided on the side of the filter element 13 away from the partition 12, and the guiding member 14 is arranged inside the support pipe 11; the guiding member 14 includes a fixed seat 141, a guiding vane 142 rotatably arranged inside the fixed seat 141, and a push rod member 144 connected to the guiding vane 142; the number of guiding vanes 142 is multiple groups, and multiple groups of guiding vanes 142 are connected by a connecting rod 143 arranged on one side thereof.

[0046] It should be noted that, along the direction in which carbon dioxide enters the storage tank 2, 14 is arranged at the upstream position of the filter element 13, and the carbon dioxide first passes through the guiding member and then passes through the filter member 13. Specifically, the outer wall of the fixing seat 141 is adapted to the inner wall of the support pipe 11, and the fixing seat 141 and the support pipe 11 are fixed by welding or bolt connection; the inside of the fixing seat 141 is a through rectangular structure, and the guiding vane 142 is arranged at the central position of the fixing seat 141, and the guiding vane 142 can be flipped inside the fixing seat 141 so as to adjust the flowing direction of carbon dioxide.

[0047] The push rod member 144 is connected to the guiding vane 142, and the push rod member 144 and the guiding vane 142 are hinged, and an elastic member is arranged on the outer side of the rod portion of the push rod member 144, and the elastic member releases elastic potential energy to push the guiding vane 142 to flip; the number of the guiding vanes 142 is multiple groups, and the multiple groups of guiding vanes 142 are equidistantly distributed at the hollow position inside the fixing seat 141; and the multiple groups of guiding vanes 142 are connected by a connecting rod 143, so as to realize the synchronous movement of the multiple groups of guiding vanes 142.

[0048] Preferably, the elastic member arranged on the outer side of the rod portion of the push rod member 144 releases elastic potential energy, so that the multiple groups of guiding vanes 142 are far away from each other, and a certain gap exists between two adjacent groups of guiding vanes 142, so as to facilitate the flow of carbon dioxide.

[0049] Furthermore, the guiding vane 142 further includes a bent portion 1421 arranged on its surface; the bent portion 1421 can guide the gas to flow downward.

[0050] In this embodiment, the cross section of the bent portion 1421 is a bent arc structure, and the bent portion corresponds to the bottom position of the filter member, so that after the carbon dioxide passes through the guiding vane 142, it is first located at the bottom of the support pipe 11 and then moves upward to the top position of the support pipe 11, so that the carbon dioxide has a rising process.

[0051] It should be noted that the downward air flow direction is the same as the direction of gravity. The particulate matter mixed in the carbon dioxide is more likely to deviate from the air flow trajectory under the action of gravitational acceleration, accelerate sedimentation to the filter surface or the bottom slag collection area, and reduce suspension and escape; large particle impurities are partially sedimentated at the bottom of the pipeline before reaching the filter, reducing the direct load on the filter and prolonging the service life of the filter.

[0052] Preferably, the downward air flow can inhibit the common turbulent vortices in the horizontal flow, form a more stable laminar flow, make the particulate matter evenly distributed and orderly impact the filter, and effectively avoid the situation of concentrated blockage of the filter.

[0053] Example 3, refer to Figures 1 to 5, which is the third embodiment of the present invention. What is different from the previous two embodiments is that: the support pipe 11 further includes a blocking member 15 disposed inside thereof; the blocking member 15 includes a piston plate 151 capable of flipping to open the passage; a reflux pipe 17 is communicated at the middle position between the blocking member 15 and the guiding member 14; the reflux pipe 17 connects the support pipe 11 and the storage tank 2.

[0054] It should be noted that the support pipe 11 is divided into a first pipe 111 and a second pipe 112, and the first pipe 111 and the second pipe 112 are fixed by means of bolt connection; the support pipe 11 adopts a detachable structure, which can better facilitate the installation of internal parts and can also reduce the manufacturing difficulty.

[0055] The blocking member 15 has an annular structure, and the outer wall of the blocking member 15 abuts against the inner wall of the support pipe 11; the piston plate 151 is hinged and rotatable with respect to the blocking member 15, and the piston plate 151 can flip relative to the blocking member 15; when gas enters the inside of the support pipe 11, the piston plate 151 is pushed open by the gas, and a gas flow passage is formed inside the blocking member 15, so that the gas can enter the inside of the support pipe 11 through the blocking member 15.

[0056] Furthermore, the reflux pipe 17 is disposed between the guiding member 14 and the blocking member 15, and the reflux pipe 17 is communicated with the storage tank 2, and the gas inside the storage tank 2 can flow reversely into the airbag through the reflux pipe 17.

[0057] Furthermore, an airbag 16 is installed at the bottom opening position of the reflux pipe 17, and the airbag 16 is located inside the support pipe 11; a pressure valve is installed inside the reflux pipe 17, and its pressure valve threshold is the same as that inside the countercurrent pipe 122.

[0058] It should be noted that the airbag 16 and the reflux pipe 17 are matched by means of threaded connection. The airbag 16 is made of rubber material and has good deformation ability. When high-pressure carbon dioxide flows back into the airbag 16 along the reflux pipe 17, the airbag 16 is filled with carbon dioxide gas and expands.

[0059] Preferably, a pressure valve the same as that inside the countercurrent pipe 122 is provided inside the reflux pipe 17. When the internal pressure of the storage tank 2 reaches a certain level, the pressure valves inside the reflux pipe 17 and the countercurrent pipe 122 are in an open state at the same time; at this time, a part of the high-pressure carbon dioxide impacts the surface of the filter member 13 reversely, and the other part enters the airbag 16 through the reflux pipe 17.

[0060] Furthermore, the airbag 16 is filled with gas and expands, and the outer wall of the airbag 16 squeezes the piston plate 151 after expansion, thereby blocking the internal passage of the support pipe 11.

[0061] In this embodiment, after the airbag 16 expands, its side wall will squeeze the piston plate 151, so that the piston plate 151 flips toward the blocking member 15, and then the internal channel of the blocking member 15 is closed, thereby effectively isolating external carbon dioxide from entering the support pipe 11.

[0062] It should be noted that during the expansion process of the airbag 16 when filled with high-pressure carbon dioxide, carbon dioxide will still enter the support pipe 11 through the hollow pipe of the sealing member 15; at this time, the carbon dioxide overflowing from the storage tank 2 will intersect with the carbon dioxide that has just entered and meet one side of the filter member 13, causing a turbulent swirl; when the carbon dioxide in the storage tank 2 flows in the opposite direction, the guide plate 142 provided can also consume the carbon dioxide, thereby further buffering its energy.

[0063] Preferably, when the airbag 16 expands to a certain volume, the airbag 16 presses the piston plate 151 against the opening position of the blocking member 15 , thereby sealing the internal channel of the blocking member 15 and isolating the external carbon dioxide from continuing to flow into the support pipe 11 .

[0064] Furthermore, when the airbag 16 expands, its outer wall contacts the end of the push rod 144 , and the push rod 144 controls the multiple groups of guide plates 142 to closely adhere to form a baffle.

[0065] It should be noted that during the continuous expansion of the airbag 16, when it blocks the internal passage of the blocking member 15, its outer wall will also contact the end of the push rod member 144 and compress the elasticity of the push rod member 144, thereby driving the multiple groups of guide vanes 142 to flip over. The multiple groups of guide vanes 142 approach each other and form a baffle, which can effectively deal with the reverse impact of carbon dioxide.

[0066] After the filter element 13 is cleaned by backwashing, the outer carbon dioxide inlet valve can be closed and the slag discharge pipe valve can be opened manually; at this time, the carbon dioxide flowing in the opposite direction is discharged from the inside of the support pipe 11 through the slag discharge pipe after flushing, and as the carbon dioxide inside the storage tank 2 gradually decreases, the volume of the airbag 16 also gradually decreases, and the push rod element 144 is not squeezed. When the pressure of the storage tank 2 is lower than the pressure valve threshold, the pressure valve is closed. At this time, the carbon dioxide remaining in the support pipe 11 is discharged through the slag discharge pipe, and the countercurrent pipe 122 and the air intake pipe 121 are both in a closed state, and no carbon dioxide will overflow, thereby completing the cleaning of impurities.

[0067] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
