Description

Technical Field

[0001] The present invention relates to the technical field of carbon measurement and capture detection, and particularly to a carbon measurement and capture detection device. Background Art

[0002] In the atmosphere, in addition to carbon-containing gases such as carbon dioxide, there are also various other gases and impurities. When directly measuring, these substances may interfere with the measuring instrument and affect the accuracy of the measurement. Through carbon capture, carbon can be separated from the complex atmospheric environment, reducing the interference of other substances and making the measurement result more accurately reflect the actual content of carbon. The concentration of carbon in the atmosphere is relatively low, and there may be large errors in directly measuring low-concentration carbon. Carbon capture can enrich the carbon in the atmosphere to a range where it is easier to accurately measure, thereby improving the accuracy and reliability of the measurement.

[0003] In the Chinese patent with the publication number CN118903994A, the invention relates to the technical field of carbon capture, and particularly to a carbon measurement automatic capture instrument, including a pre-washing tank. A fixing plate is fixedly connected inside the pre-washing tank. A plurality of grooves are formed at the top of the fixing plate, and filter bags are arranged inside the grooves. A cleaning mechanism is arranged inside two of the filter bags, and two hammering mechanisms are arranged at the bottom of the fixing plate. Through the combined action of the hammering mechanism and the shaking mechanism, under the action of the hammering mechanism, there is a downward acting force on the cross plate. Also, under the mutual cooperation of the movable plate, the vertical plate, the tension spring and the spring, the cross plate is driven to shake up and down to clean the impurities on the cross plate, preventing excessive attachment of impurities on the cross plate, which may cause the overall weight of the cross plate to gradually increase, affecting the stability and service life of the cross plate, and further affecting the filtering effect of the entire system.

[0004] After the existing carbon measurement and capture device filters and pre-washes the gas to be detected to remove particulate impurities inside, when using amine-coated silica gel particles to absorb and capture carbon in the gas, the gas is usually directly introduced into the adsorption column filled with absorption particles for repeated use. After the gas flows through it multiple times inside, a channeling effect is easily formed, causing most of the subsequent gas to be captured to flow along a certain route and make repeated contact with certain positions of the amine-coated silica gel particles inside. Some amine-coated silica gel particles are located in dead-end positions and have insufficient contact, affecting the capture efficiency of carbon in the gas. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the defect that after the gas flows through the adsorption column multiple times in the prior art, a channeling effect is easily formed, so that most of the gas to be subsequently captured passes through according to a certain route and makes repeated contacts with certain positions of the amino-coated silica gel particles therein. Some of the amino-coated silica gel particles are located in dead corners and the contact is insufficient, affecting the carbon capture efficiency of the gas. The present invention proposes a carbon metering capture detection device.

[0006] To solve the above technical problem, the technical solution adopted by the present invention is to include a detection device bracket, on the top of which a carbon capture box is installed. Inside the carbon capture box, three groups of channel components are arranged at equal intervals.

A channel is opened inside the panel, and the opening size of the channel gradually increases from top to bottom.

Detailed implementation manners

[0019] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, those of ordinary skill in the art can propose various interchangeable structural ways and implementation manners. Therefore, the following detailed implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present invention, and should not be regarded as the whole of the present invention or as a limitation or restriction on the technical solution of the present invention.

[0020] According to an embodiment of the present invention in combination with Figures 1 to 9Shown. A carbon measurement and capture detection device includes a detection device support 1. At the top of the detection device support 1, a carbon capture box 2 is installed. Inside the carbon capture box 2, three groups of channel components 3 are arranged at equal intervals. The channel component 3 includes a side strip 301, and two groups of panels 302 are symmetrically arranged on the side of the side strip 301, and the panels 302 are fixedly connected to the side strip 301. A channel 303 is opened inside the panel 302. Both the panel 302 and the channel 303 are serpentine. When the gas is blown upward from its outside, the serpentine curved surface can effectively increase the contact area with the gas. The opening size of the channel 303 gradually increases from top to bottom. When the gas flows downward inside the serpentine cavity 305, the opening on the upper side of the channel 303 is smaller, and the gas inside is more difficult to leak out, which can increase the distance that the gas flows along the inside of the serpentine cavity 305 as much as possible, making it more fully contact with the carbon capture balls 5 inside. The larger the opening of the channel 303 is closer to the bottom, which means that the closer to the bottom, the larger the area of the carbon capture balls 5 exposed on the outside. The gas with a higher carbon content that just flows through the side of the panel 302 first contacts the carbon capture balls 5 with a larger area. And the closer to the bottom, because the air flow just blows upward through the lower ventilation holes 12, the intensity of the air flow is greater. Even if the opening of the channel 303 is larger and the amount of leaked gas is slightly more, it has little impact on the main air flow that blows upward from bottom to top. Gradually upward, the intensity of the main air flow is weaker, and at the same time, the opening size of the channel 303 also becomes smaller, and the amount of gas leaking out inside is also less, which can minimize the impact on the upward moving main air flow. At the same time, the air flow leaking out through the channel 303 can move upward again with the main air flow, enter the upper ventilation cavity 8 through the upper ventilation holes 20, and then enter the serpentine cavity 305 again through the channel air inlet 9 for circulation, increasing the number of times of contact between the gas and the carbon capture balls 5, and thus increasing the carbon capture efficiency of the carbon capture balls 5 for the gas.

[0021] The side strip 301 and the panel 302 jointly enclose to form a serpentine cavity 305. Inside the serpentine cavity 305, a partition component 4 is arranged. Carbon capture balls 5 are evenly arranged on both sides of the partition component 4. The material of the carbon capture balls 5 can be selected as amine-coated silica gel. Amine has strong nucleophilicity. Carbon dioxide is an acidic gas, and a chemical reaction can occur between the two, and this reaction is reversible. Under certain conditions, such as increasing the temperature, carbon dioxide can be released again, enabling the regeneration of the amine coating and allowing the continuous operation of carbon dioxide capture. Silica gel itself has a highly developed porous structure and a large surface area. After the amine coating is loaded on the surface of the silica gel, the porous structure of the silica gel is not completely destroyed. Gas molecules can diffuse into the silica gel through these pores, and carbon dioxide molecules will be temporarily adsorbed in the pores, thereby increasing the opportunity for carbon dioxide to contact and react with the amine and improving the capture efficiency.

[0022] The partition assembly 4 includes a middle bar 401, and two groups of side bars 402 are symmetrically arranged on the sides of the middle bar 401. The middle bar 401 is fixedly connected to the side bars 402. The carbon capture ball 5 is clearance-matched with the middle bar 401 and the side bars 402. The middle bar 401 and the two groups of side bars 402 cooperate with each other to form a partition with an I-shaped cross section, which is used to separate the carbon capture balls 5 on both sides. The inner wall of the side bar 301 is evenly distributed with protrusions 304, and the protrusions 304 are fixedly connected to the side bar 301. The ends of the protrusions 304 are set to be spherical, and the protrusions 304 and the carbon capture balls 5 are spaced apart. When the airflow blows downward from the top of the serpentine cavity 305, the protrusion 304 on one side lifts up the serpentine cavity 305 and partially exposes it to the airflow, and the airflow forms a pressure difference on the surface of the carbon capture ball 5. When the airflow bypasses the carbon capture ball 5, the airflow speeds on the side close to the middle strip 401 and the side close to the protrusion 304 are different, generating torque, which pushes the carbon capture ball 5 to rotate inside the serpentine cavity 305, so that all surfaces of the carbon capture ball 5 can contact with the airflow, thereby improving the adsorption efficiency and preventing the airflow from passing through only one side of the carbon capture ball 5, causing wear after multiple blows, forming a fixed path, and affecting adsorption.

[0023] The bottom end of the carbon capture box 2 is fixedly connected to an air intake pipe 13, one side of the air intake pipe 13 is connected to a nitrogen gas storage tank 16, the nitrogen gas storage tank 16 is fixedly connected to the detection device bracket 1, the other side of the air intake 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, which is installed on the top of the detection device bracket 1.

[0024] The carbon capture box 2 is fixedly connected to a lower partition plate 10, 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 capture box 2 are enclosed together to form a lower vent cavity 11, and the lower vent cavity 11 is connected to the air intake pipe 13. The side of the lower vent hole 12 is fixedly connected to a channel outlet 19, and the top of the channel outlet 19 is connected to the serpentine cavity 305, and the bottom of the channel outlet 19 is connected to the serpentine cavity 305. There is an exhaust box 14, which is fixedly connected to the bottom of the carbon capture box 2, and an exhaust pipe 15 is fixedly connected to the side of the exhaust box 14. An upper partition plate 7 is fixedly connected to the inside of the carbon capture box 2, and the upper partition plate 7 is fixedly connected to the top of the panel 302. The upper partition plate 7 and the carbon capture box 2 together enclose an upper ventilation cavity 8. The upper partition plate 7 is fixedly connected to a channel air inlet 9, and the top of the channel air inlet 9 extends to the inside of the upper ventilation cavity 8, and the channel air inlet 9 is connected to the upper ventilation cavity 8, and the bottom end of the channel air inlet 9 is connected to the serpentine cavity 305.

[0025] The gas that has undergone preliminary pre - washing treatment enters the interior of the lower ventilation cavity 11 through the intake pipeline 13, and is blown into the interior of the carbon capture box 2 through the dispersion and diversion of each lower ventilation hole 12, blows upward along the surface of the panel 302, then enters the interior of the upper ventilation cavity 8 through the upper ventilation hole 20, enters the serpentine cavity 305 through the channel intake port 9, and finally discharges outward from the channel outlet 19.

[0026] An upper ventilation hole 20 is provided inside the upper partition plate 7, and a one - way ventilation component 6 is installed inside the upper ventilation hole 20. The one - way ventilation component 6 includes a connecting column 601, and the connecting column 601 runs through the interior of the upper ventilation hole 20. A sealing piece 604 is fixedly connected to the top end of the connecting column 601, and the outer diameter of the sealing piece 604 is larger than the inner diameter of the upper ventilation hole 20. An anti - detachment strip 603 is fixedly connected to the bottom end of the connecting column 601. A spring 602 is nested outside the connecting column 601. The top end of the spring 602 is fixedly connected to the upper partition plate 7, and the bottom end of the spring 602 is fixedly connected to the anti - detachment strip 603. Under the action of the air flow, pushing the sealing piece 604 upward can make the upper ventilation hole 20 in an open state, enabling the gas to enter the interior of the upper ventilation cavity 8 upward through the upper ventilation hole 20. When the air flow inside the upper ventilation cavity 8 wants to flow back into the interior of the carbon capture box 2 through the upper ventilation hole 20, under the action of the spring 602, it will pull the sealing piece 604 to move downward to block the upper ventilation hole 20.

[0027] Workflow: Under the pumping action of the exhaust fan 18, the gas to be measured enters the interior of the pre - washing tank 17 to receive initial filtration and pre - washing, removing some solid particulate matter and other impurities in the gas. The gas after filtration treatment enters the interior of the lower ventilation cavity 11 through the intake pipeline 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 surface of the carbon capture balls 5 exposed through the channels 303 for initial carbon capture. Finally, it enters the interior of the upper ventilation cavity 8 through the upper ventilation hole 20. Under 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 downward 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 intake port 9 and gradually flows downward along the serpentine cavity 305. At the same time, the carbon capture balls 5 inside it will absorb and capture the carbon in the gas flowing through its surface. The remaining gas after capture flows into the exhaust box 14 through the channel outlet 19 and is discharged outward through the exhaust pipeline 15; After the capture is completed, the nitrogen gas inside the nitrogen gas storage tank 16 can be introduced into the interior of the carbon capture box 2 through the intake pipe 13. At the same time, the interior of the carbon capture box 2 is heated, and the nitrogen gas is used to purge the carbon capture balls 5 adsorbed with carbon, so that the carbon is desorbed from the inside for detection.

[0028] The technical scope of the present invention is not limited to the content described above. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
