Description

Technical Field

[0001] The present invention relates to the technical field of carbon dioxide capture, and specifically to a carbon dioxide capture and compression device based on carbon neutrality. Background Art

[0002] Carbon dioxide capture technology refers to separating, capturing, and concentrating carbon dioxide from the source of generation (such as chemical plants, thermal power plants, steel plants, etc.) through technical means. Currently, common capture technologies include absorption, compression, condensation, membrane separation, etc.

[0003] Chinese Patent CN114588754B discloses a device and method for air carbon dioxide capture and compression, including a carbon dioxide capture device, a carbon dioxide compression device, and a housing. Both the carbon dioxide capture device and the carbon dioxide compression device are located inside the housing. The carbon dioxide capture device includes an air capture component, and further includes a purification component connected to the air capture component. The purification component includes a purification pool located inside the housing. By pre-collecting the captured carbon dioxide gas, the present invention uniformly introduces the carbon dioxide gas into the compressor, and at the same time uses a diaphragm compressor to replace the traditional carbon dioxide compressor to solve the problems that the traditional carbon dioxide compressor is not conducive to controlling the compression process, cannot meet small-batch compression, and has low compression efficiency.

[0004] In the above technical solution, during the capture process, a combination of a carbon dioxide permeable membrane and an electrostatic dust removal rod is used to pre-treat the air entering the system to remove dust impurities in the air to ensure the efficiency and stability of the subsequent capture process. However, after long-term operation, dust particles will gradually accumulate on the surface of the carbon dioxide permeable membrane and the surface of the electrostatic dust removal rod. These attached dusts not only reduce the effective filtration area of the membrane, lower the dust removal efficiency of the electrostatic dust removal rod, but also significantly hinder the gas flow, thus seriously weakening the overall filtration performance. More critically, the accumulation of dust is a dynamic process, and the accumulation rate of dust is closely related to factors such as environmental conditions and equipment operation duration. Therefore, relying on manual regular cleaning often fails to respond in a timely manner, which not only increases the operation and maintenance costs, but also may cause the equipment to operate in a non-optimal state, affecting the overall efficiency of carbon dioxide capture.

[0012] Preferably, the clamping receiving reel includes a limiting shaft body rotatably installed on the first mounting frame. An installation bayonet is provided on the limiting shaft body, and an assembled shaft body is installed on the installation bayonet.

[0013] Preferably, the dust cleaning assembly includes a second mounting bracket installed between the winding device and the air inlet housing.

[0016] The beneficial effects of the present invention compared with the prior art are as follows:

[0017] 1. By introducing the self-cleaning trapping assembly, the present invention significantly improves the cleaning efficiency. The self-cleaning trapping assembly integrates the pull-out permeable membrane, the winding device, the dust cleaning assembly and the synchronous pressing device, realizing continuous and automatic cleaning of the electrostatic dust removal rod and the pull-out permeable membrane. Compared with the traditional manual regular cleaning method, this automatic cleaning mechanism can remove the accumulated dust more timely and effectively, avoiding the problems of reduced filtration performance and blocked gas flow caused by dust accumulation. This not only improves the operation efficiency of the equipment, but also reduces the increase in operation and maintenance costs caused by untimely cleaning.

[0018] 2. The design of the self-cleaning trapping assembly fully considers the dynamic process of dust accumulation and its impact on the trapping efficiency. Through the unlocking of the synchronous pressing device and the start of the winding device, the pull-out permeable membrane can move regularly and automatically and be cleaned by the cleaning module and the dust cleaning assembly. This process not only removes the dust on the surface of the electrostatic dust removal rod and the pull-out permeable membrane, but also ensures the continuous and efficient operation of the trapping assembly. Therefore, the equipment can maintain a stable trapping efficiency under various environmental conditions and equipment operation durations, avoiding the performance fluctuations of the equipment caused by dust accumulation, thus ensuring the continuity and stability of the carbon dioxide trapping process.

[0019] 3. Through the integration of the self-cleaning capture component, the present invention realizes the continuous and efficient cleaning of key components during the capture process, thereby optimizing the overall performance. The automated cleaning mechanism reduces the frequency of manual intervention and lowers the operation and maintenance costs. At the same time, the cleaned electrostatic precipitator rod and the draw penetration membrane can maintain a high dust removal efficiency and filtration performance, ensuring that the clean gas enters the compression equipment for subsequent processing. This not only improves the capture efficiency but also extends the service life of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] To further understand the features, technical means, specific purposes, and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation manners.

[0033] See Figures 1 to 10 As shown, a carbon dioxide capture and compression device based on carbon neutrality includes a self-cleaning capture assembly installed at the intake end of the compression device. The self-cleaning capture assembly includes an intake housing 1, a drawable permeable membrane 2, a rewinding device 3, a dust cleaning assembly 4, an electrostatic dust removal rod 5, and a synchronous pressing device 6. The intake housing 1 is installed at the intake end of the compression device. A filter chamber is provided inside the intake housing 1. A negative pressure fan 14 is installed at the bottom of the intake housing 1. Multiple groups of electrostatic dust removal rods 5 are provided and are installed in the filter chamber at equal intervals. The rewinding device 3 is installed beside the intake housing 1. Multiple groups of drawable permeable membranes 2 are provided. The multiple groups of drawable permeable membranes 2 are installed on the rewinding device 3. The filtering surface of the drawable permeable membrane 2 is arranged inside the intake housing 1. A cleaning module 24 is further provided on the drawable permeable membrane 2. The cleaning module 24 is used to clean the electrostatic dust removal rod 5. Two groups of dust cleaning assemblies 4 are provided. Each group of dust cleaning assemblies 4 is arranged between the rewinding device 3 and the intake housing 1. The cleaning surface provided by the dust cleaning assembly 4 is in contact with the drawable permeable membrane 2. The synchronous pressing device 6 is installed inside the intake housing 1. The synchronous pressing device 6 is used to limit and fix the drawable permeable membrane 2.

[0034] After the compression device is started, the intake housing 1 is located at the intake end of the compression device. A negative pressure effect is generated by the internal negative pressure fan 14 to attract the gas-dust mixture into the filtration chamber. During this process, multiple groups of electrostatic dust removal rods 5 installed at equal intervals are energized. The electrostatic dust removal rods 5 utilize the electrostatic effect to adsorb dust particles in the gas, preliminarily purifying the air. Subsequently, the gas pretreated by electrostatic dust removal continues to penetrate the draw penetration membrane 2, and the draw penetration membrane 2 further removes tiny impurities and remaining dust particles in the gas, ensuring that only clean gas can enter the interior of the compression device for subsequent processing.

[0035] As the device continues to operate, dust will gradually accumulate on the surfaces of the electrostatic dust removal rods 5 and the draw penetration membrane 2, affecting the dust removal efficiency and the gas flow rate. Therefore, when the preset cleaning cycle is reached or it is detected that the dust has accumulated to a certain extent, the synchronous pressing device 6 first unlocks the fixation of the draw penetration membrane 2, allowing the draw penetration membrane 2 to move freely. Subsequently, the winding device 3 is started to drive multiple groups of draw penetration membranes 2 to move along the preset path, passing through the electrostatic dust removal rods 5 and the dust cleaning assembly 4.

[0036] During the movement of the draw penetration membrane 2, the cleaning module 24 provided on the draw penetration membrane 2 moves synchronously. The cleaning module 24 is designed with a structure that contacts the surface of the electrostatic dust removal rod 5, so as to achieve physical cleaning of the surface when passing through the gaps between the electrostatic dust removal rods 5, scraping off the accumulated dust and attaching it to the draw penetration membrane 2. At the same time, the contact friction between the draw penetration membrane 2 and the dust cleaning assembly 4 utilizes the special material or structure of the dust cleaning assembly 4 to effectively remove the dust attached to the membrane surface, realizing self-cleaning of the draw penetration membrane 2.

[0037] Through the self-cleaning trapping assembly, continuous and efficient cleaning of the electrostatic dust removal rods 5 and the draw penetration membrane 2 can be achieved, without the need for regular manual intervention, reducing the operation and maintenance costs. At the same time, it ensures the continuity and stability of the carbon dioxide capture process and improves the overall efficiency.

[0038] See Figures 1 to 4 As shown, a diversion interface 13 is installed at the top of the intake housing 1. The diversion interface 13 is communicated with the filtration chamber inside the intake housing 1. A plurality of installation slide rails 12 are provided on the inner wall of the filtration chamber, and a plurality of insertion ports 11 are also provided on both sides of the filtration chamber. The insertion ports 11 correspond to the draw penetration membranes 2 one by one.

[0039] The intake housing 1 is installed at the intake end of the compression equipment. The filtration chamber of the intake housing 1 is the main place for the preliminary purification of gas. The intake housing 1 generates a negative pressure effect through the negative pressure fan 14 installed at the bottom, and this effect can attract the external gas and dust mixture into the filtration chamber. To ensure the smooth entry of gas, a diversion interface 13 is provided at the top of the intake housing 1, and this interface is connected to the designated suction pipe to achieve the effective guiding and transportation of gas. The diversion interface 13 and the intake housing 1 are detachably connected, which not only facilitates subsequent manual positioning and maintenance but also the cleaning of the diversion interface 13.

[0040] A plurality of installation slide rails 12 are provided on the inner wall of the chamber. The main function of the installation slide rails 12 is to install the synchronous pressing device 6, and the synchronous pressing device 6 can fix or release the draw penetration membrane 2 when needed. In addition, a plurality of insertion ports 11 are provided on both sides of the filtration chamber, and the insertion ports 11 correspond to the draw penetration membrane 2 one by one, providing a necessary movement path for the draw penetration membrane 2.

[0041] See Figures 1 to 9 As shown, the draw penetration membrane 2 is composed of a carbon dioxide permeation membrane 21 and a limit wire 22. Limit wires 22 are provided on both sides of the carbon dioxide permeation membrane 21, and mounting holes 23 are provided on the carbon dioxide permeation membrane 21 for installing the cleaning module 24.

[0042] The carbon dioxide permeation membrane 21 is a prior art, and its working principle and specific structure will not be elaborated in detail here.

[0043] The draw penetration membrane 2 is mainly composed of a carbon dioxide permeation membrane 21 and a limit wire 22. The carbon dioxide permeation membrane 21, as the filtration core, is responsible for further removing the tiny impurities and residual dust particles in the gas after pretreatment by the electrostatic dust removal rod 5 to ensure the cleanliness of the gas. The limit wires 22 provided on both sides of the draw penetration membrane 2 not only enhance the tensile performance of the carbon dioxide permeation membrane 21 but also prevent the deformation of the membrane body during the winding and pulling processes, thus effectively improving the service life and stability of the carbon dioxide permeation membrane 21. In addition, the preset mounting holes 23 on the carbon dioxide permeation membrane 21 are designed specifically for installing the cleaning module 24, enabling the cleaning module 24 to be firmly attached to the membrane.

[0044] When the carbon dioxide permeation membrane 21 reaches the preset cleaning cycle or it is detected that the dust accumulation reaches a certain threshold, the winding device 3 is activated to pull the draw penetration membrane 2 to move along the established path. During this process, the cleaning module 24 moves with the draw penetration membrane 2. Through the physical contact between the cleaning module 24 and the electrostatic dust removal rod 5, the dust accumulated on the surface of the electrostatic dust removal rod 5 is scraped off; at the same time, through the frictional contact between the draw penetration membrane 2 and the dust cleaning component 4, the dust cleaning component 4 effectively removes the dust attached to the surface of the draw penetration membrane 2, realizing a continuous and efficient self-cleaning function.

[0045] See Figures 4 to 8 As shown, the cleaning module 24 includes an upper cleaning block 241 and a lower cleaning block 242. A clamping hole is provided at the bottom of the upper cleaning block 241, and a plurality of limiting clamping teeth 2421 are provided on the lower cleaning block 242. The limiting clamping teeth 2421 are in clamping fit with the clamping hole, and extrusion cleaning structures 243 are provided at the tops of both the upper cleaning block 241 and the lower cleaning block 242.

[0046] The bottom of the upper cleaning block 241 is designed with a clamping hole, while a plurality of limiting clamping teeth 2421 are provided on the lower cleaning block 242. The limiting clamping teeth 2421 form a clamping fit with the clamping hole, ensuring that the upper cleaning block 241 and the lower cleaning block 242 can be stably and closely installed on the surface of the carbon dioxide permeable membrane 21. This not only facilitates the installation or disassembly operation by the staff but also ensures the stability and continuity of the cleaning module 24 during the process of pulling the permeable membrane 2.

[0047] When the pulling permeable membrane 2 is pulled by the winding device 3 due to reaching the preset cleaning cycle or the dust accumulating to a certain extent, the cleaning module 24 moves along with it. During this process, the extrusion cleaning structures 243 at the tops of the upper cleaning block 241 and the lower cleaning block 242 come into contact with the electrostatic dust removal rod 5. The extrusion cleaning structure 243 can effectively press against the surface of the electrostatic dust removal rod 5, thereby increasing the friction force and improving the cleaning effect.

[0048] With the continuous movement of the pulling permeable membrane 2, the cleaning module 24 physically cleans the surface of the electrostatic dust removal rod 5, scraping off the accumulated dust and attaching it to the pulling permeable membrane 2. At the same time, the contact friction between the pulling permeable membrane 2 and the dust cleaning component 4 further removes the dust attached to the membrane surface, realizing a continuous and efficient self-cleaning function.

[0049] See Figure 8 and Figure 9 As shown, the extrusion cleaning structure 243 includes two elastic bending plates 2431. A cleaning push block 2432 is provided at the top of each elastic bending plate 2431, and a V-shaped connecting piece 2433 is provided between the two elastic bending plates 2431.

[0050] The extrusion cleaning structure 243 is installed at the tops of the upper cleaning block 241 and the lower cleaning block 242. The extrusion cleaning structure 243 is composed of two elastic bending plates 2431, and a cleaning push block 2432 is equipped at the top of each elastic bending plate 2431. In addition, the two elastic bending plates 2431 are connected by a V-shaped connecting piece 2433. This design not only ensures the linkage between the elastic bending plates 2431 but also enhances the resilience.

[0051] During the process that the draw penetration membrane 2 is pulled by the winding device 3, thereby driving the cleaning module 24 to move along a predetermined path, the extrusion cleaning structure 243 comes into contact with the electrostatic dust removal rod 5 accordingly. Since the elastic bending plate 2431 has good elasticity and can be moderately bent according to the surface morphology of the electrostatic dust removal rod 5, it ensures that the cleaning push block 2432 closely adheres to the surface of the electrostatic dust removal rod 5.

[0052] The close contact between the cleaning push block 2432 and the electrostatic dust removal rod 5, combined with the continuous thrust provided by the elastic bending plate 2431, enables the cleaning push block 2432 to effectively scrape and clean the surface of the electrostatic dust removal rod 5.

[0053] The V-shaped connecting piece 2433 plays a key role in the extrusion cleaning structure 243. The V-shaped connecting piece 2433 not only enhances the structural stability between the two elastic bending plates 2431, but also optimizes the resilience performance of the elastic bending plates 2431 through the geometric shape of the V-shaped connecting piece 2433. When the cleaning push block 2432 contacts the electrostatic dust removal rod 5 and generates a scraping force, the V-shaped connecting piece 2433 can ensure that the two elastic bending plates 2431 respond to the external force in a coordinated manner, thereby maintaining the continuity and efficiency of the cleaning process.

[0054] See Figure 1 and Figure 2 As shown, the winding device 3 includes two first mounting frames 31 symmetrically installed on both sides of the intake housing 1. Each first mounting frame 31 is provided with multiple groups of guide shafts 32 and clamping winding shafts 33. The winding device 3 further includes a synchronous driving device 34 for driving multiple clamping winding shafts 33 to rotate.

[0055] Each first mounting frame 31 is equipped with multiple groups of guide shafts 32 and clamping winding shafts 33. The function of the guide shaft 32 is to provide a smooth moving path for the draw penetration membrane 2 to ensure stability and accuracy during the winding process. The clamping winding shaft 33 is used to fix and wind the draw penetration membrane 2.

[0056] As the core component of the winding device 3, the synchronous driving device 34 is responsible for driving multiple clamping winding shafts 33 to rotate synchronously. The synchronous driving device 34 adopts existing technology, and its working principle and specific structure will not be elaborated in detail here. When the synchronous driving device 34 is started, multiple clamping winding shafts 33 start to rotate synchronously under the action of the driving force, and this rotational movement will drive the draw penetration membrane 2 fixed on the clamping winding shafts 33 to perform winding movement.

[0057] During the winding process of the draw penetration membrane 2, due to the synchronous rotation of the card receiving reel 33, the draw penetration membrane 2 can be evenly and orderly wound around the card receiving reel 33, thus realizing the switching and updating of the draw penetration membrane 2. This winding action not only ensures the effective replacement of the draw penetration membrane 2 within the cleaning cycle, but also guarantees the stability and efficiency of the compression equipment during continuous operation.

[0058] See Figure 2 and Figure 7 As shown in the figure, the card receiving reel 33 includes a limiting shaft body 331 rotatably installed on the first mounting frame 31. An installation bayonet 3311 is provided on the limiting shaft body 331, and an assembled shaft body 332 is installed on the installation bayonet 3311.

[0059] The installation bayonet 3311 of the limiting shaft body 331 is used to carry and fix the draw penetration membrane 2. On the installation bayonet 3311, a detachable assembled shaft body 332 is further assembled. The assembled shaft body 332 is used to firmly press the draw penetration membrane 2 within the installation bayonet 3311. The limiting shaft body 331 is in transmission connection with the synchronous drive device 34 to ensure that the limiting shaft body 331 can rotate accordingly when the synchronous drive device 34 is started. Through the synchronous drive of the synchronous drive device 34 for multiple limiting shaft bodies 331, the synchronous rotation of the card receiving reel 33 is realized.

[0060] During the replacement process of the draw penetration membrane 2, the staff first removes the assembled shaft body 332 to smoothly place one end of the new draw penetration membrane 2 into the installation bayonet 3311. Subsequently, the assembled shaft body 332 is reassembled, and the draw penetration membrane 2 is effectively fixed on the installation bayonet 3311 by the pressing action of the assembled shaft body 332. This process ensures the stable installation of the draw penetration membrane 2 on the card receiving reel 33 and provides a basis for subsequent winding operations.

[0061] See Figure 2 and Figure 10 As shown in the figure, the dust cleaning component 4 includes a second mounting frame 41 installed between the winding device 3 and the air inlet housing 1. Multiple cleaning mounting rails 42 are installed on the second mounting frame 41. Multiple scraping bars 43 and multiple cleaning brushes 44 are installed inside the cleaning mounting rails 42. The multiple scraping bars 43 and the multiple cleaning brushes 44 are both inclined. The dust cleaning component 4 further includes a material receiving box 45 installed below the second mounting frame 41.

[0062] The second mounting bracket 41 is firmly mounted between the winding device 3 and the intake housing 1, providing a stable support platform for the cleaning mounting rail 42. The cleaning mounting rail 42 is arranged along the movement path of the draw permeable membrane 2 to ensure sufficient cleaning of the draw permeable membrane 2. Inside the cleaning mounting rail 42, a plurality of scraping bars 43 and cleaning brushes 44 are installed. The scraping bars 43 and cleaning brushes 44 are both arranged at an inclined angle so as to produce an effective scraping effect when the draw permeable membrane 2 passes through, thereby removing the dust attached to the membrane surface.

[0063] When the winding device 3 is started and drives multiple groups of draw permeable membranes 2 to move along the preset path, multiple groups of draw permeable membranes 2 will pass through multiple groups of cleaning mounting rails 42. During this process, the scraping bars 43 and cleaning brushes 44 will come into contact with the surface of the draw permeable membrane 2, and the accumulated dust will be removed through the scraping action. The dust removed will fall into the material receiving box 45 along a specific path. The design of the material receiving box 45 facilitates the collection and subsequent treatment of the dust.

[0064] Through the continuous operation of the dust cleaning component 4, it can be ensured that the draw permeable membrane 2 remains clean during the winding switching process, thereby improving the overall efficiency and operation stability of the carbon dioxide capture and compression equipment. At the same time, the design of the dust cleaning component 4 also takes into account the convenience of operation and maintenance. The easy disassembly and cleaning characteristics of the material receiving box 45 reduce the operation and maintenance costs and work intensity.

[0065] See Figures 1 to 5 As shown, the synchronous pressing device 6 includes a plurality of pressing frames 61 installed inside the intake housing 1. The pressing frames 61 are slidably connected to the installation slide rails 12. An elastic abutting ring is provided at the bottom of each pressing frame 61 for contacting the draw permeable membrane 2. An adjusting shaft 62 is provided at the side of each pressing frame 61. The synchronous pressing device 6 further includes a synchronous adjusting device 63 installed at the side of the intake housing 1, and the synchronous adjusting device 63 is used to synchronously drive the plurality of pressing frames 61 to move synchronously.

[0066] The pressing frame 61 is slidably connected to the installation slide rails 12 inside the intake housing 1, ensuring that the pressing frame 61 can perform stable lifting and lowering movements along the slide rails. An elastic abutting ring is installed at the bottom of each pressing frame 61 for contacting the draw permeable membrane 2 to achieve the fixation or release of the draw permeable membrane 2. In addition, an adjusting shaft 62 is provided at the side of each pressing frame 61. The synchronous adjusting device 63 is installed at the side of the intake housing 1, and the synchronous adjusting device 63 has the ability to synchronously drive a plurality of adjusting shafts 62, thereby ensuring that all the pressing frames 61 can perform lifting and lowering movements simultaneously.

[0067] During the cleaning process of the pull-out permeable membrane 2, the synchronous adjustment device 63 will be started first, and the corresponding pressing frames 61 will be driven to rise synchronously by pushing the multiple adjustment shafts 62. As the pressing frames 61 rise, the elastic resistance ring at the bottom will be separated from the pull-out permeable membrane 2, thereby releasing the fixation of the pull-out permeable membrane 2. At this time, the pull-out permeable membrane 2 can be moved along the preset path driven by the winding device 3 for subsequent cleaning work.

[0068] When the pull-out permeable membrane 2 is moved and cleaned, the synchronous adjustment device 63 will start again, and drive the pressing frame 61 to descend synchronously by pushing the adjustment shaft 62 in the opposite direction. As the pressing frame 61 descends, the elastic resistance ring at the bottom will contact the pull-out permeable membrane 2 again, and the pull-out permeable membrane 2 will be fixed in the designated area through the elastic characteristics of the elastic resistance ring. In this way, the stability of the gas during the filtration process is ensured.

[0069] See also Figure 5 and Figure 6 As shown, the synchronous adjustment device 63 includes a push adjustment plate 631 slidably mounted on the side of the air intake housing 1 , and a plurality of inclined guide plates 6311 are distributed on the push adjustment plate 631 . The synchronous adjustment device 63 also includes a linear driver 632 for driving the push adjustment plate 631 to move.

[0070] The push adjustment plate 631 slides stably with the side of the air intake housing 1 , and the inclined guide plate 6311 is used to form a conflict with the adjustment shaft 62 of the pressing frame 61 , thereby achieving the lifting control of the pressing frame 61 .

[0071] When the linear driver 632 is activated, it pushes the push adjustment plate 631 to move along a preset path. The movement of the push adjustment plate 631 drives the inclined guide plate 6311 to form a conflict with the plurality of adjustment shafts 62 .

[0072] When the push adjustment plate 631 moves, the upper part of the inclined guide plate 6311 will contact the adjustment shaft 62, thereby pushing the adjustment shaft 62 and the downward pressing frame 61 connected thereto to rise synchronously. As the downward pressing frame 61 rises, the elastic contact ring at the bottom will break away from the contact with the pull-out permeable membrane 2, thereby releasing the pull-out permeable membrane 2.

[0073] On the contrary, when the linear drive 632 is started in the reverse direction, the lower part of the inclined guide plate 6311 will contact the adjustment shaft 62, thereby driving the pressing frame 61 to descend synchronously. As the pressing frame 61 descends, the elastic contact ring at the bottom will contact the pull-out permeable membrane 2 again, thereby fixing the pull-out permeable membrane 2.

[0074] Specific working principle:

[0075] After the compression device is started, the intake housing 1 is located at the intake end of the compression device. A negative pressure effect is generated by the internal negative pressure fan 14 to attract the gas-dust mixture into the filtration chamber. During this process, multiple groups of equally spaced electrostatic dust removal rods 5 are energized to work, and the electrostatic effect of the electrostatic dust removal rods 5 is used to adsorb dust particles in the gas, preliminarily purifying the air. Subsequently, the gas pretreated by electrostatic dust removal continues to penetrate the draw penetration membrane 2, and the draw penetration membrane 2 further removes tiny impurities and remaining dust particles in the gas, ensuring that only clean gas can enter the interior of the compression device for subsequent processing.

[0076] As the device continues to operate, dust will gradually accumulate on the surfaces of the electrostatic dust removal rods 5 and the draw penetration membrane 2, affecting the dust removal efficiency and the gas flow rate. Therefore, when the preset cleaning cycle is reached or it is detected that the dust has accumulated to a certain extent, the synchronous pressing device 6 first unlocks the fixation of the draw penetration membrane 2, allowing the draw penetration membrane 2 to move freely. Subsequently, the winding device 3 is started to drive multiple groups of draw penetration membranes 2 to move along the preset path, passing through the electrostatic dust removal rods 5 and the dust cleaning assembly 4.

[0077] During the movement of the draw penetration membrane 2, the cleaning module 24 provided on the draw penetration membrane 2 moves synchronously. The cleaning module 24 is designed with a structure that contacts the surface of the electrostatic dust removal rod 5, so as to achieve physical cleaning of the surface when passing through the gap of the electrostatic dust removal rod 5, scraping off the accumulated dust and attaching it to the draw penetration membrane 2. At the same time, the contact friction between the draw penetration membrane 2 and the dust cleaning assembly 4 uses the special material or structure of the dust cleaning assembly 4 to effectively remove the dust attached to the membrane surface, realizing the self-cleaning of the draw penetration membrane 2.

[0078] Through the self-cleaning capture assembly, continuous and efficient cleaning of the electrostatic dust removal rods 5 and the draw penetration membrane 2 can be achieved, without the need for regular manual intervention, reducing the operation and maintenance costs. At the same time, the continuity and stability of the carbon dioxide capture process are ensured, improving the overall efficiency.

[0079] The above embodiments only represent one or several implementation manners of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the protection scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
