Description

Technical Field

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

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

[0003] Chinese patent number CN114588754B discloses a device and method for capturing and compressing carbon dioxide from air, including a carbon dioxide capturing device, a carbon dioxide compressing device and a shell, wherein the carbon dioxide capturing device and the carbon dioxide compressing device are both located inside the shell, and the carbon dioxide capturing device includes an air capturing component: and also includes: a purification component connected to the air capturing component, wherein the purification component includes a purification pool, and the purification pool is located inside the shell. The present invention pre-collects the captured carbon dioxide gas, thereby uniformly introducing the carbon dioxide gas into the compressor, and at the same time adopts a diaphragm compressor to replace the traditional carbon dioxide compressor, so as to solve the problem that the traditional carbon dioxide compressor is not conducive to controlling the compression process, and cannot meet the requirements of small batch compression and low compression efficiency.

[0004] In the capture process, the above technical solution uses a combination of carbon dioxide permeable membrane and electrostatic precipitator rods to pre-treat the air entering the system and remove dust impurities in the air to ensure the efficiency and stability of the subsequent capture process. However, after a long period of operation, dust particles will gradually accumulate on the surface of the carbon dioxide permeable membrane and the surface of the electrostatic precipitator rod. These attached dusts not only reduce the effective filtration area of ​​the membrane and reduce the dust removal efficiency of the electrostatic precipitator rod, but also significantly hinder the circulation of gas, thereby seriously weakening the overall filtration performance. More importantly, 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 time. Therefore, it is often difficult to respond in a timely manner by relying on manual regular cleaning, 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.

[0018] 3.

DETAILED DESCRIPTION

[0030] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0031] See also Figures 1 to 10 As shown, a carbon dioxide capture and compression device based on carbon neutralization includes a self-cleaning capture component installed at the air inlet end of the compression device, and the self-cleaning capture component includes an air inlet shell 1, a pull-out permeable membrane 2, a winding device 3, a dust cleaning component 4, an electrostatic dust removal rod 5 and a synchronous pressing device 6; the air inlet shell 1 is installed at the air inlet end of the compression device, and a filter chamber is provided inside the air inlet shell 1, and a negative pressure fan 14 is installed at the bottom of the air inlet shell 1; a plurality of electrostatic dust removal rods 5 are provided and are installed in the filter chamber at equal intervals; the winding device 3 is installed beside the air inlet shell 1. side; a plurality of pull-out permeable membranes 2 are provided, and the plurality of pull-out permeable membranes 2 are installed on the winding device 3, and the filtering surface of the pull-out permeable membrane 2 is arranged inside the air intake shell 1, and a cleaning module 24 is also provided on the pull-out permeable membrane 2, and the cleaning module 24 is used to clean the electrostatic dust removal rod 5; two groups of cleaning components 4 are provided, and each group of cleaning components 4 is arranged between the winding device 3 and the air intake shell 1, and the cleaning surface of the cleaning component 4 is in contact with the pull-out permeable membrane 2; a synchronous pressing device 6 is installed inside the air intake shell 1, and the synchronous pressing device 6 is used to limit and fix the pull-out permeable membrane 2.

[0032] After the compression device is started, the air intake housing 1 is located at the air intake end of the compression device, and a negative pressure effect is generated through the internal negative pressure fan 14 to attract the gas and dust mixture into the filter chamber. In this process, multiple groups of electrostatic precipitator rods 5 installed at equal intervals are powered on to work, and the electrostatic precipitator rods 5 use the electrostatic effect to adsorb dust particles in the gas and preliminarily purify the air. Subsequently, the gas pre-treated by electrostatic precipitator continues to penetrate the pull-pull permeable membrane 2, which 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.

[0033] As the equipment continues to operate, dust will gradually accumulate on the surface of the electrostatic dust removal rod 5 and the pull-out permeable membrane 2, affecting the dust removal efficiency and gas circulation speed. For this reason, when the preset cleaning cycle is reached or dust accumulation to a certain extent is detected, the synchronous pressing device 6 first unlocks the pull-out permeable membrane 2, allowing the pull-out permeable membrane 2 to move freely. Subsequently, the winding device 3 is started, driving multiple groups of pull-out permeable membranes 2 to move along a preset path, passing through the electrostatic dust removal rod 5 and the cleaning assembly 4.

[0034] During the movement of the pull-out permeable membrane 2, the cleaning module 24 provided on the pull-out permeable membrane 2 moves synchronously, and the cleaning module 24 is designed to be in contact with the surface of the electrostatic dust removal rod 5, so as to physically clean the surface when passing through the gap of the electrostatic dust removal rod 5, and the accumulated dust is scraped off and attached to the pull-out permeable membrane 2. At the same time, the contact friction between the pull-out permeable membrane 2 and the cleaning component 4, using the special material or structure of the cleaning component 4, effectively removes the dust attached to the membrane surface, and realizes the self-cleaning of the pull-out permeable membrane 2.

[0035] The self-cleaning capture assembly can achieve continuous and efficient cleaning of the electrostatic precipitator rod 5 and the pull-out permeable membrane 2 without the need for regular manual intervention, thereby reducing operation and maintenance costs, while ensuring the continuity and stability of the carbon dioxide capture process and improving overall efficiency.

[0036] See also Figures 1 to 4 As shown, a flow guide interface 13 is installed on the top of the air inlet shell 1, and the flow guide interface 13 is connected to the filter chamber inside the air inlet shell 1. The inner wall of the filter chamber is provided with a plurality of mounting slide rails 12, and a plurality of insertion openings 11 are also provided on both sides of the filter chamber. The insertion openings 11 correspond one-to-one to the pull-out permeable membrane 2.

[0037] The air intake housing 1 is installed at the air intake end of the compression equipment, and the filter chamber of the air intake housing 1 is the main place for the preliminary purification of the gas. The air intake housing 1 generates a negative pressure effect through the negative pressure fan 14 installed at the bottom, which can attract the external gas and dust mixture into the filter chamber. In order to ensure that the gas can enter smoothly, a guide interface 13 is provided on the top of the air intake housing 1. The interface is connected to the designated suction pipe to achieve effective guidance and transportation of the gas. The guide interface 13 and the air intake housing 1 are connected in a detachable manner, which is not only convenient for subsequent manual positioning and maintenance, but also convenient for the cleaning of the guide interface 13.

[0038] The inner wall of the chamber is provided with a plurality of mounting rails 12. The main function of the mounting rails 12 is to install the synchronous pressing device 6, which can fix or release the pull-out permeable membrane 2 when needed. In addition, a plurality of insertion openings 11 are provided on both sides of the filtration chamber, and the insertion openings 11 correspond to the pull-out permeable membrane 2 one by one, providing a necessary moving path for the pull-out permeable membrane 2.

[0039] See also Figures 1 to 9 As shown, the pull-out permeable membrane 2 is composed of a carbon dioxide permeable membrane 21 and a limiting wire 22 . The limiting wires 22 are arranged on both sides of the carbon dioxide permeable membrane 21 . The carbon dioxide permeable membrane 21 is provided with a mounting hole 23 , and the mounting hole 23 is used to install a cleaning module 24 .

[0040] The carbon dioxide permeable membrane 21 is a prior art, and its working principle and specific structure are not described in detail here.

[0041] The pull-out permeable membrane 2 is mainly composed of a carbon dioxide permeable membrane 21 and a limiting wire drawing 22. The carbon dioxide permeable membrane 21, as a filtering core, is responsible for further removing 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 limiting wire drawing 22 set on both sides of the pull-out permeable membrane 2 not only enhances the tensile strength of the carbon dioxide permeable membrane 21, but also prevents deformation of the membrane body during winding and pulling, thereby effectively improving the service life and stability of the carbon dioxide permeable membrane 21. In addition, the preset mounting hole 23 on the carbon dioxide permeable membrane 21 is specially designed for installing the cleaning module 24, so that the cleaning module 24 can be firmly attached to the membrane.

[0042] When the carbon dioxide permeable membrane 21 is used to the preset cleaning cycle or dust accumulation reaches a certain threshold, the winding device 3 is started to pull the pull-out permeable membrane 2 to move along a predetermined path. In this process, the cleaning module 24 moves with the pull-out permeable membrane 2, and the dust accumulated on the surface of the electrostatic dust removal rod 5 is scraped off through the physical contact between the cleaning module 24 and the electrostatic dust removal rod 5; at the same time, the pull-out permeable membrane 2 is in friction contact with the cleaning component 4, and the cleaning component 4 effectively removes the dust attached to the surface of the pull-out permeable membrane 2, realizing a continuous and efficient self-cleaning function.

[0043] See also 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 engaged with the clamping hole, and an extrusion cleaning structure 243 is provided on the top of the upper cleaning block 241 and the lower cleaning block 242.

[0044] The bottom of the upper cleaning block 241 is designed with a clamping hole, and the lower cleaning block 242 is provided with a plurality of limiting clamping teeth 2421. The limiting clamping teeth 2421 and the clamping holes form a clamping fit to ensure that the upper cleaning block 241 and the lower cleaning block 242 can be firmly and snugly installed on the surface of the carbon dioxide permeable membrane 21. This not only facilitates the installation or disassembly operation of the staff, but also ensures the stability and continuity of the cleaning module 24 during the process of pulling the permeable membrane 21.

[0045] When the drawn permeable membrane 2 is pulled by the winding device 3 because the preset cleaning cycle is reached or dust accumulates to a certain extent, the cleaning module 24 moves together. During this process, the squeezing cleaning structure 243 on the top of the upper cleaning block 241 and the lower cleaning block 242 comes into contact with the electrostatic dust removal rod 5. The squeezing cleaning structure 243 can effectively press the surface of the electrostatic dust removal rod 5, thereby increasing friction and improving the cleaning effect.

[0046] As the pulled permeable membrane 2 continues to move, the cleaning module 24 physically cleans the surface of the electrostatic dust removal rod 5, scrapes off the accumulated dust and attaches it to the pulled permeable membrane 2. At the same time, the contact friction between the pulled permeable membrane 2 and the cleaning component 4 further removes the dust attached to the membrane surface, realizing a continuous and efficient self-cleaning function.

[0047] See also Figure 8 and Fig. 9 As shown, the extrusion cleaning structure 243 includes two elastic bending plates 2431 , a cleaning push block 2432 is provided on the top of each elastic bending plate 2431 , and a V-shaped connecting piece 2433 is provided between the two elastic bending plates 2431 .

[0048] The extrusion cleaning structure 243 is installed on the top 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 the top of each elastic bending plate 2431 is equipped with a cleaning push block 2432. 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.

[0049] When the permeable membrane 2 is pulled by the winding device 3 and the cleaning module 24 is driven to move along a predetermined path, the extrusion cleaning structure 243 comes into contact with the electrostatic dust removal rod 5. Since the elastic bending plate 2431 has good elasticity, it can be bent appropriately according to the surface morphology of the electrostatic dust removal rod 5, ensuring that the cleaning push block 2432 is closely attached to the surface of the electrostatic dust removal rod 5.

[0050] The close contact between the cleaning push block 2432 and the electrostatic dust removal rod 5 , coupled 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 .

[0051] The V-shaped connector 2433 plays a key role in the extrusion cleaning structure 243. The V-shaped connector 2433 not only enhances the structural stability between the two elastic bending plates 2431, but also optimizes the resilience of the elastic bending plates 2431 through the geometric shape of the V-shaped connector 2433. When the cleaning push block 2432 contacts the electrostatic dust removal rod 5 and generates a scraping force, the V-shaped connector 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.

[0052] See also Figure 1 and Figure 2 As shown, the winding device 3 includes two first mounting frames 31 symmetrically mounted on both sides of the air intake housing 1, each first mounting frame 31 is provided with multiple sets of guide shafts 32 and card receiving reels 33, and the winding device 3 also includes a synchronous driving device 34 for driving multiple card receiving reels 33 to rotate.

[0053] Each first mounting frame 31 is equipped with multiple sets of guide shafts 32 and card receiving reels 33. The guide shafts 32 provide a smooth moving path for the pulled permeable membrane 2 to ensure stability and accuracy during the winding process. The card receiving reels 33 are used to fix and wind up the pulled permeable membrane 2.

[0054] The synchronous drive device 34 is the core component of the winding device 3 and is responsible for driving the multiple card receiving reels 33 to rotate synchronously. The synchronous drive device 34 adopts the existing technology, and the working principle and specific structure are not described in detail here. When the synchronous drive device 34 is started, the multiple card receiving reels 33 start to rotate synchronously under the action of the driving force, and this rotation action will drive the pull-out permeable membrane 2 fixed on the card receiving reel 33 to reel and move.

[0055] During the rewinding process of the pull-out permeable membrane 2, due to the synchronous rotation of the card receiving reel 33, the pull-out permeable membrane 2 can be evenly and orderly wound on the card receiving reel 33, thereby realizing the switching and renewal of the pull-out permeable membrane 2. This rewinding action not only ensures the effective replacement of the pull-out permeable membrane 2 during the cleaning cycle, but also ensures the stability and efficiency of the compression equipment during continuous operation.

[0056] See also Figure 2 and Figure 7 As shown, the card receiving reel 33 includes a limiting shaft 331 rotatably mounted on the first mounting frame 31 , a mounting bayonet 3311 is provided on the limiting shaft 331 , and an assembling shaft 332 is mounted on the mounting bayonet 3311 .

[0057] The mounting bayonet 3311 of the limiting shaft body 331 is used to carry and fix the pull-out permeable membrane 2. A detachable assembly shaft body 332 is further mounted on the mounting bayonet 3311, and the assembly shaft body 332 is used to firmly press the pull-out permeable membrane 2 into the mounting bayonet 3311. The limiting shaft body 331 is connected to the synchronous drive device 34 in a transmission manner to ensure that the limiting shaft body 331 can rotate when the synchronous drive device 34 is started. The synchronous drive device 34 synchronously drives multiple limiting shaft bodies 331, thereby realizing the synchronous rotation of the card receiving reel 33.

[0058] During the replacement of the pull-out permeable membrane 2, the staff first removes the assembly shaft 332 so that one end of the new pull-out permeable membrane 2 can be smoothly placed in the installation bayonet 3311. Then, the assembly shaft 332 is reassembled, and the pull-out permeable membrane 2 is effectively fixed on the installation bayonet 3311 by the pressing action of the assembly shaft 332. This process ensures the stable installation of the pull-out permeable membrane 2 on the card receiving reel 33, providing a basis for the subsequent winding operation.

[0059] See also Figure 2 and Fig.10 As shown, the cleaning component 4 includes a second mounting frame 41 installed between the winding device 3 and the air intake shell 1, and multiple groups of cleaning mounting rails 42 are installed on the second mounting frame 41. Multiple scraping strips 43 and multiple cleaning brushes 44 are installed inside the cleaning mounting rails 42. The multiple scraping strips 43 and the multiple cleaning brushes 44 are all inclined. The cleaning component 4 also includes a material receiving box 45 installed below the second mounting frame 41.

[0060] The second mounting frame 41 is firmly mounted between the winding device 3 and the air inlet 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 pulled permeable membrane 2 to ensure that the pulled permeable membrane 2 is fully cleaned. Inside the cleaning mounting rail 42, a plurality of scraping strips 43 and cleaning brushes 44 are installed, and the scraping strips 43 and cleaning brushes 44 are arranged at an oblique angle so that when the pulled permeable membrane 2 passes through, an effective scraping effect can be generated, thereby removing dust attached to the membrane surface.

[0061] When the winding device 3 is started, the multiple groups of pull-out permeable membranes 2 are driven to move along the preset path, and the multiple groups of pull-out permeable membranes 2 will pass through the multiple groups of cleaning mounting rails 42. In this process, the scraper bar 43 and the cleaning brush 44 will come into contact with the surface of the pull-out permeable membrane 2, and the accumulated dust will be removed by scraping. The cleaned dust will fall into the receiving box 45 along a specific path. The design of the receiving box 45 is convenient for the collection and subsequent treatment of dust.

[0062] The continuous operation of the dust cleaning component 4 ensures that the drawn permeable membrane 2 remains clean during the winding and switching process, thereby improving the overall efficiency and operational 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.

[0063] See also Figures 1 to 5 As shown, the synchronous pressing device 6 includes a plurality of pressing frames 61 installed inside the air inlet shell 1, the pressing frames 61 are slidably connected to the mounting slide rails 12, an elastic resistance ring is provided at the bottom of each pressing frame 61, the elastic resistance ring is used to contact and pull the permeable membrane 2, and an adjusting shaft 62 is provided on the side of each pressing frame 61. The synchronous pressing device 6 also includes a synchronous adjustment device 63 installed on the side of the air inlet shell 1, and the synchronous adjustment device 63 is used to synchronously drive the plurality of pressing frames 61 to move synchronously.

[0064] The pressing frame 61 is slidably connected to the mounting rail 12 inside the air inlet housing 1, ensuring that the pressing frame 61 can stably move up and down along the rail. An elastic contact ring is installed at the bottom of each pressing frame 61, and the elastic contact ring is used to form contact with the pull-out permeable membrane 2, thereby achieving the fixation or release of the pull-out permeable membrane 2. In addition, an adjustment shaft 62 is provided on the side of each pressing frame 61, and a synchronous adjustment device 63 is installed on the side of the air inlet housing 1. The synchronous adjustment device 63 has the ability to synchronously drive multiple adjustment shafts 62, thereby ensuring that all pressing frames 61 can move up and down at the same time.

[0065] 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.

[0066] 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.

[0067] 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.

[0068] 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 .

[0069] 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 .

[0070] 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.

[0071] 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.

[0072] Specific working principle: After the compression device is started, the air intake housing 1 is located at the air intake end of the compression device, and a negative pressure effect is generated through the internal negative pressure fan 14 to attract the gas and dust mixture into the filter chamber. In this process, multiple groups of electrostatic dust removal rods 5 installed at equal intervals are powered on to work, and the electrostatic effect of the electrostatic dust removal rods 5 is used to adsorb dust particles in the gas to preliminarily purify the air. Subsequently, the gas pre-treated by electrostatic dust removal continues to penetrate the pull-pull permeable membrane 2, which 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.

[0073] As the equipment continues to operate, dust will gradually accumulate on the surface of the electrostatic dust removal rod 5 and the pull-out permeable membrane 2, affecting the dust removal efficiency and gas circulation speed. For this reason, when the preset cleaning cycle is reached or dust accumulation to a certain extent is detected, the synchronous pressing device 6 first unlocks the pull-out permeable membrane 2, allowing the pull-out permeable membrane 2 to move freely. Subsequently, the winding device 3 is started, driving multiple groups of pull-out permeable membranes 2 to move along a preset path, passing through the electrostatic dust removal rod 5 and the cleaning assembly 4.

[0074] During the movement of the pull-out permeable membrane 2, the cleaning module 24 provided on the pull-out permeable membrane 2 moves synchronously, and the cleaning module 24 is designed to be in contact with the surface of the electrostatic dust removal rod 5, so as to physically clean the surface when passing through the gap of the electrostatic dust removal rod 5, and the accumulated dust is scraped off and attached to the pull-out permeable membrane 2. At the same time, the contact friction between the pull-out permeable membrane 2 and the cleaning component 4, using the special material or structure of the cleaning component 4, effectively removes the dust attached to the membrane surface, and realizes the self-cleaning of the pull-out permeable membrane 2.

[0075] The self-cleaning capture assembly can achieve continuous and efficient cleaning of the electrostatic precipitator rod 5 and the pull-out permeable membrane 2 without the need for regular manual intervention, thereby reducing operation and maintenance costs, while ensuring the continuity and stability of the carbon dioxide capture process and improving overall efficiency.

[0076] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
