Abstract

This invention proposes a carbon metering and capture detection device, belonging to the field of carbon metering and capture detection technology. To address the issue that after gas flows through the adsorption column multiple times, a channeling effect easily forms, causing subsequent gas to follow a fixed path and resulting in uneven contact with the amine-coated silica gel particles, thus affecting the carbon capture efficiency, this invention provides a channel that exposes the carbon-capturing balls. This allows the gas to initially adsorb upon contact with the outer surface of the carbon-capturing balls. Subsequently, the gas moves downwards along the serpentine cavity, repeatedly contacting the carbon-capturing balls inside. This repeated contact and adsorption increases the probability of carbon contact between the gas and the carbon-capturing balls. Furthermore, the downward movement of the airflow carries the carbon-capturing balls, ensuring full contact with all surfaces of the balls and preventing only a few areas from receiving back-and-forth sweeping, thus preventing a fixed path that affects the carbon capture efficiency.

Description

Technical Field

[0001] This invention relates to the field of carbon metering, capture and detection technology, and in particular to a carbon metering, capture and detection device. Background Technology

[0002] Besides carbon dioxide and other carbon-containing gases, the atmosphere contains various other gases and impurities. Direct measurement of these substances can interfere with measuring instruments, affecting accuracy. Carbon capture separates carbon from the complex atmospheric environment, reducing interference from other substances and allowing the measurement results to more accurately reflect the actual carbon content. Since atmospheric carbon concentration is relatively low, direct measurement of low-concentration carbon can lead to significant errors. Carbon capture enriches atmospheric carbon, bringing its concentration to a more easily measurable range, thereby improving the accuracy and reliability of the measurement.

[0003] In Chinese patent publication CN118903994A, this invention relates to the field of carbon capture technology, specifically to an automatic carbon metering capture device, including a pre-wash tank. A fixed plate is fixedly connected inside the pre-wash tank. Multiple grooves are formed on the top of the fixed plate, and filter bags are placed inside each groove. Two of the filter bags have cleaning mechanisms inside. Two hammering mechanisms are located at the bottom of the fixed plate. This invention utilizes the combined action of the hammering and shaking mechanisms. The hammering mechanism exerts a downward force on the horizontal plate, while the movable plate, vertical plate, tension spring, and spring work together to cause the horizontal plate to shake up and down, cleaning impurities from the horizontal plate and preventing excessive impurities from adhering to it. This gradually increases the mass of the horizontal plate, leading to an increase in its overall weight, which may affect the stability and service life of the horizontal plate, thus impacting the overall filtration effect of the system.

[0004] Existing carbon metering and capture devices, after filtering and pre-washing the gas to be detected to remove particulate impurities, typically pass the gas directly into the adsorption column containing the absorbent particles when using amine-coated silica gel particles to absorb and capture carbon in the gas. This process is repeated, and after the gas flows through the column multiple times, a channeling effect is easily formed. This causes most of the gas to be captured to follow a certain path and repeatedly contact certain positions of the amine-coated silica gel particles. However, some amine-coated silica gel particles are located in dead zones, resulting in insufficient contact and affecting the carbon capture efficiency in the gas. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defects of the prior art, which is that after the gas flows through the adsorption column multiple times, a channeling effect is easily formed, so that most of the gas to be captured later follows a certain route and makes repeated contact with certain positions of the amine-coated silica particles. However, some amine-coated silica particles are located in dead corners and do not make sufficient contact, which affects the capture efficiency of carbon in the gas. The present invention proposes a carbon metering capture and detection device.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention includes a detection device bracket, a carbon collection box installed on the top of the detection device bracket, three sets of channel components equally spaced inside the carbon collection box, each channel component including side strips, and two sets of panels symmetrically arranged on the sides of the side strips, with the panels fixedly connected to the side strips, each panel having a channel inside, the opening size of the channel gradually increasing from top to bottom, the side strips and panels together forming a serpentine cavity, and a partition component inside the serpentine cavity, with carbon collection balls evenly arranged on both sides of the partition component, each partition component including a middle strip, and two sets of side strips symmetrically arranged on the sides of the middle strip, with the middle strip and side strips fixedly connected, the carbon collection balls having a clearance fit with the middle strip and side strips;

[0007] An air inlet pipe is fixedly connected to the bottom of the carbon capture box. A nitrogen storage tank is connected to one side of the air inlet pipe. The nitrogen storage tank is fixedly connected to the detection device bracket. A pre-wash tank is connected to the other side of the air inlet pipe. The pre-wash tank is fixedly connected to the detection device bracket. An exhaust fan is connected to the bottom of the pre-wash tank. The exhaust fan is installed on the top of the detection device bracket.

[0008] Preferably, the inner wall of the side strip is uniformly distributed with protrusions, the protrusions are fixedly connected to the side strip, the ends of the protrusions are spherical, and the protrusions and carbon capturing balls are fitted with a gap.

[0009] Preferably, the carbon capture box is fixedly connected to a lower partition plate, which is fixedly connected to the bottom of the panel. The lower partition plate has four rows of lower vent holes at equal intervals inside, and each row of lower vent holes is spaced apart from the serpentine cavity.

[0010] Preferably, the lower partition plate and the carbon capture box together form a lower ventilation cavity, and the lower ventilation cavity is connected to the air inlet pipe.

[0011] Preferably, a channel outlet is fixedly connected to the side of the lower vent, and the top of the channel outlet is connected to the serpentine cavity.

[0012] Preferably, the bottom end of the air outlet of the channel is connected to an exhaust box, the exhaust box is fixedly connected to the bottom of the carbon collection box, and an exhaust pipe is fixedly connected to the side of the exhaust box.

[0013] Preferably, an upper partition plate is fixedly connected inside the carbon capture box, and the upper partition plate is fixedly connected to the top of the panel. The upper partition plate and the carbon capture box together form an upper ventilation cavity.

[0014] Preferably, the upper partition plate is fixedly connected to a channel air inlet, the top end of the channel air inlet extends into the interior of the upper ventilation cavity, and the channel air inlet is connected to the upper ventilation cavity, and the bottom end of the channel air inlet is connected to the serpentine cavity.

[0015] Preferably, the upper partition plate has an upper vent hole inside, and a one-way ventilation component is installed inside the upper vent hole.

[0016] Preferably, the one-way ventilation assembly includes a connecting column that extends through the interior of the upper ventilation hole.

The top of the spring is fixedly connected to the upper partition plate, and the bottom of the spring is fixedly connected to the anti-detachment strip.

[0017] Compared with the prior art, the beneficial effects of the present invention include: the channel allows the carbon trapping ball to be exposed, so that the gas comes into contact with the carbon trapping ball on the outer side for initial adsorption. Then the gas can move downward along the serpentine cavity and repeatedly contact the carbon trapping ball inside. The repeated contact and adsorption increases the probability of carbon in the gas contacting the carbon trapping ball, thereby increasing the possibility of its capture. In addition, the airflow can carry the carbon trapping ball to rotate during the downward movement, so that it can fully contact all surfaces of the carbon trapping ball, preventing only a few positions from being swept back and forth, forming a fixed path, which would affect its carbon capture efficiency.

[0029] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention.

[0030] According to one embodiment of the present invention, Figures 1 to 9 As shown. A carbon metering and capture detection device includes a detection device support 1. A carbon capture box 2 is mounted on the top of the detection device support 1. Three sets of channel assemblies 3 are evenly spaced inside the carbon capture box 2. Each channel assembly 3 includes a side strip 301, and two sets of panels 302 are symmetrically arranged on the sides of the side strip 301. The panels 302 are fixedly connected to the side strip 301. Channels 303 are formed inside the panels 302. Both the panels 302 and the channels 303 are serpentine in shape. When gas is blown upwards from the outside, the serpentine surface effectively increases the contact area with the gas. The opening size of the channels 303 gradually increases from top to bottom. When gas flows downwards inside the serpentine cavity 303, the opening on the upper side of the channel 303 is smaller, making it more difficult for the gas to leak out. This maximizes the path the gas travels through the serpentine cavity 305, allowing it to contact the carbon capture balls 5 more fully. The opening of the channel 303 is larger towards the bottom. This means that the closer to the bottom, the larger the area of ​​the carbon trapping ball 5 exposed on the outside. This allows the gas with a higher carbon content that has just flowed through the side of the panel 302 to first come into contact with the larger area of ​​the carbon trapping ball 5. Also, the closer to the bottom, the stronger the airflow is because the airflow has just been blown upward through the lower vent 12. Even if the opening of the channel 303 is large and the amount of gas seeping out is slightly larger, the impact on the main airflow blowing upward is not significant. Gradually upward, the strength of the main airflow weakens, and the size of the opening of the channel 303 also decreases. The amount of gas seeping out of its interior is also less, thus minimizing the impact on the upward-moving main airflow. At the same time, the airflow seeping out through the channel 303 can move upward again with the main airflow, enter the interior of the upper vent cavity 8 through the upper vent 20, and then enter the interior of the serpentine cavity 305 through the channel inlet 9 for circulation. This increases the number of times the gas comes into contact with the carbon trapping ball 5, thereby increasing the efficiency of the carbon trapping ball 5 in capturing carbon in the gas.

[0031] The side strip 301 and the panel 302 together form a serpentine cavity 305, and a partition component 4 is provided inside the serpentine cavity 305. Carbon capturing balls 5 are evenly arranged on both sides of the partition component 4. The material of the carbon capturing balls 5 can be amine-coated silicone. Amine has strong nucleophilicity, and carbon dioxide is an acidic gas. The two can react chemically, and this reaction is reversible. Under certain conditions, such as increasing the temperature, carbon dioxide can be released, allowing the amine coating to regenerate and continue to capture carbon dioxide. Silicone itself has a highly developed porous structure and a large surface area. After the amine coating is loaded on the surface of the silicone, it does not completely destroy the porous structure of the silicone. Gas molecules can diffuse into the interior of the silicone through these pores. Carbon dioxide molecules will be temporarily adsorbed in the pores, thereby increasing the chance of carbon dioxide contacting and reacting with amine and improving the capture efficiency.

[0032] The separating component 4 includes a middle strip 401, with two sets of side strips 402 symmetrically arranged on its sides. The middle strip 401 and the side strips 402 are fixedly connected. The carbon capturing balls 5 are fitted with both the middle strip 401 and the side strips 402 with clearance. The middle strip 401 and the two sets of side strips 402 cooperate with each other to form a partition with a cross-section similar to an I-beam, used to separate the carbon capturing balls 5 on both sides. The inner wall of the side strips 301 has protrusions 304 evenly distributed, which are fixedly connected to the side strips 301. The ends of the protrusions 304 are spherical, and the protrusions 304 and the carbon capturing balls 5 are... With the gap fitting, when the airflow blows downward from the top of the serpentine cavity 305, the protrusion 304 on one side lifts the serpentine cavity 305 and partially exposes it to the airflow. The airflow creates a pressure difference on the surface of the carbon trapping ball 5. When the airflow passes around the carbon trapping ball 5, the airflow speed is different on the side near the middle strip 401 and the side near the protrusion 304, generating torque, which pushes the carbon trapping ball 5 to rotate inside the serpentine cavity 305. This allows all surfaces of the carbon trapping ball 5 to contact the airflow, thereby improving the adsorption efficiency and preventing the airflow from only passing through one side of the carbon trapping ball 5. After repeated sweeping, wear will occur, forming a fixed path and affecting adsorption.

[0033] The bottom of the carbon collection box 2 is fixedly connected to an air inlet pipe 13. One side of the air inlet pipe 13 is connected to a nitrogen storage tank 16. The nitrogen storage tank 16 is fixedly connected to the detection device bracket 1. The other side of the air inlet pipe 13 is connected to a pre-wash tank 17. The pre-wash tank 17 is fixedly connected to the detection device bracket 1, and the bottom of the pre-wash tank 17 is connected to an exhaust fan 18. The exhaust fan 18 is installed on the top of the detection device bracket 1.

[0034] A lower partition plate 10 is fixedly connected to the inside of the carbon collection box 2, and the lower partition plate 10 is fixedly connected to the bottom end of the panel 302. Four rows of lower vent holes 12 are evenly spaced inside the lower partition plate 10, and each row of lower vent holes 12 is spaced apart from the serpentine cavity 305. The lower partition plate 10 and the carbon collection box 2 together form a lower vent cavity 11, which is connected to the air inlet pipe 13. A channel outlet 19 is fixedly connected to the side of the lower vent hole 12. The top end of the channel outlet 19 is connected to the serpentine cavity 305, and the bottom end of the channel outlet 19 is connected to... An exhaust box 14 is fixedly connected to the bottom of the carbon collection box 2. An exhaust pipe 15 is fixedly connected to the side of the exhaust box 14. An upper partition plate 7 is fixedly connected inside the carbon collection box 2 and is fixedly connected to the top of the panel 302. The upper partition plate 7 and the carbon collection box 2 together form an upper ventilation cavity 8. A channel air inlet 9 is fixedly connected to the upper partition plate 7. The top of the channel air inlet 9 extends into the interior of the upper ventilation cavity 8 and is connected to the upper ventilation cavity 8. The bottom of the channel air inlet 9 is connected to the serpentine cavity 305.

[0035] After preliminary pre-washing, the gas enters the lower ventilation cavity 11 through the air inlet pipe 13 and is blown into the carbon collection box 2 through the dispersion guide of each lower ventilation hole 12. It is then blown upward along the surface of the panel 302, enters the upper ventilation cavity 8 through the upper ventilation hole 20, and enters the serpentine cavity 305 through the channel air inlet 9, and is finally discharged outward from the channel air outlet 19.

[0036] The upper partition plate 7 has an upper vent 20 inside, and a one-way ventilation component 6 is installed inside the upper vent 20. The one-way ventilation component 6 includes a connecting post 601, which passes through the upper vent 20. A sealing piece 604 is fixedly connected to the top of the connecting post 601, and the outer diameter of the sealing piece 604 is larger than the inner diameter of the upper vent 20. An anti-detachment strip 603 is fixedly connected to the bottom of the connecting post 601. A spring 602 is nested outside the connecting post 601, and the top of the spring 602 is connected to... The upper partition plates 7 are fixedly connected, and the bottom end of the spring 602 is fixedly connected to the anti-detachment strip 603. Under the action of airflow, the sealing plate 604 is pushed upward to open the upper vent 20, allowing gas to enter the upper vent cavity 8 through the upper vent 20. When the airflow inside the upper vent cavity 8 wants to flow back into the carbon collection box 2 through the upper vent 20, the sealing plate 604 will be pulled downward by the spring 602 to block the upper vent 20.

[0037] Workflow: Under the suction action of the exhaust fan 18, the gas to be tested enters the pre-wash tank 17 for initial filtration and pre-washing to remove some solid particles and other impurities. After filtration, the gas enters the lower ventilation cavity 11 through the air inlet pipe 13, then is blown upward through each lower ventilation hole 12, and flows upward along the outer wall of each panel 302. While flowing upward, it comes into contact with the side of the carbon capturing ball 5 exposed through the channel 303 for initial carbon capture. Finally, it enters the upper ventilation cavity 8 through the upper ventilation hole 20. Due to the action of the one-way ventilation component 6, the gas can only enter the interior of the upper ventilation cavity 8 from bottom to top through the upper ventilation hole 20, but cannot flow back down into the carbon capture box 2 through the upper ventilation cavity 8. Then, the gas inside the upper ventilation cavity 8 enters the interior of the serpentine cavity 305 through the channel inlet 9, and gradually flows down along the serpentine cavity 305. At the same time, the carbon capture ball 5 inside it will absorb and capture the carbon inside the gas flowing over its surface. After capture, the remaining gas flows into the exhaust box 14 through the channel outlet 19 and is discharged outward through the exhaust pipe 15.

[0038] After the collection is completed, the nitrogen in the nitrogen storage tank 16 can be introduced into the carbon collection box 2 through the air inlet pipe 13. At the same time, the carbon collection box 2 is heated, and the carbon collection ball 5 with adsorbed carbon is purged with nitrogen to desorb the carbon from its interior for detection.

[0039] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
