Description

Technical Field

[0001] The present invention relates to a carbon dioxide gas detection technology, and in particular to an atmospheric carbon dioxide concentration monitoring device. Background Art

[0002] In today's society, with the acceleration of industrialization, carbon dioxide emissions and monitoring have become important research directions in the field of environmental science and engineering. As one of the main greenhouse gases, changes in carbon dioxide concentration in the atmosphere have a profound impact on the global climate and ecological environment. Therefore, accurate monitoring of changes in carbon dioxide concentration in different environmental media is crucial for assessing climate change trends, formulating emission reduction strategies, and ensuring environmental sustainability.

[0003] A Chinese invention patent with publication number CN118330136A discloses an online monitoring device for carbon dioxide emission concentration. During operation, the output shaft of the motor is connected to a stirring device, which is located in the reaction tank. The stirring device is a hollow structure with a plurality of flue gas holes provided thereon. The stirring device is connected to the flue gas inlet. During the reaction, the liquid in the reaction tank is stirred by the stirring device. At the same time, during the stirring process, the flue gas holes on the stirring device send the flue gas into the liquid in the reaction tank, thereby allowing the liquid and the flue gas to react thoroughly, resulting in higher measurement accuracy, and reducing the number of devices and occupying a small area.

[0004] When in use, existing equipment can only be applied to a part of the carbon dioxide treatment procedures, which greatly limits the detection of commonly used carbon dioxide. At the same time, when detecting carbon dioxide, it is easy for the residual particles inside the carbon dioxide to clog the discharge hole, thereby affecting the subsequent detection results. Therefore, an atmospheric carbon dioxide concentration monitoring device has been developed. Summary of the Invention

[0005] The purpose of the present invention is to provide an atmospheric carbon dioxide concentration monitoring device to solve the above-mentioned deficiencies in the prior art.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an atmospheric carbon dioxide concentration monitoring device, comprising a purification box, a guide tube provided at the upper end of the purification box, and a filter assembly provided on the inner wall of the guide tube, through which carbon dioxide is preliminarily filtered;

[0007] The filter assembly includes a fixed cylinder connected to the inner wall of the guide tube, the inner cavity of the fixed cylinder is provided with a clamping rod, and the lower end of the fixed cylinder is connected to the outlet pipe, and the outer surface of the clamping rod is connected to the inner wall of the guide tube through multiple groups of protrusions;

[0008] A fixing rod is provided at the upper end of the clamping rod, and a plurality of groups of magnetic filter blocks are provided on the outer surface of the fixing rod, and the plurality of groups of magnetic filter blocks are evenly distributed on the outer surface of the fixing rod. At the same time, a collection pipe is connected to the outer surface of the fixing cylinder and located above the magnetic filter blocks, for introducing external carbon dioxide into the interior of the fixing cylinder;

[0009] The exclusion component is assembled in the inner cavity of the purification box and is located below the filter component, and is used to classify the separated carbon dioxide.

[0010] As a further optimization solution of the present invention, the outer surface of the purification box is connected to an air outlet pipe, and a filter plate is provided in the inner cavity of the purification box and below the guide pipe, and the outer surface of the filter plate is rotatably connected to the inner wall of the purification box.

[0011] As a further optimization solution of the present invention, a cover plate is provided at the upper end of the fixed cylinder, and the outer surface of the lower end of the cover plate is rotatably connected to the inner wall of the fixed cylinder.

[0012] As a further optimization scheme of the present invention, the outer surface of the fixed cylinder is clamped with a limiting block, and a positioning rod is rotatably installed on the upper end of the limiting block. One end of the positioning rod passes through and extends to the other end of the limiting block, and at the same time, the lower end of the positioning rod is in contact with the upper end of the cover plate.

[0013] As a further optimization solution of the present invention, the exclusion component includes a screw connected to the filter plate, and a movable block is threadedly mounted on the outer surface of the screw.

[0014] As a further optimization solution of the present invention, a plurality of groups of connection blocks are provided on the outer surface of the movable block, and the plurality of groups of connection blocks are evenly distributed on the outer surface of the movable block.

[0018] As a further optimization solution of the present invention, a rubber plug is provided at the lower end of the fixing plate, and the longitudinal section of the rubber plug is in the shape of an inverted trapezoid.

[0019] Compared with the existing technology, the atmospheric carbon dioxide concentration monitoring equipment provided by the present invention, when carbon dioxide enters the interior of the fixed cylinder through the collection tube, adsorbs particulate matter in the carbon dioxide through multiple groups of magnetic filter blocks, and discharges the treated carbon dioxide through the outlet pipe at the lower end of the fixed cylinder, and then transfers the treated carbon dioxide to the interior of the purification box for subsequent operations. When the carbon dioxide is processed, the accumulation of particulate matter is reduced, which may cause blockage of the discharge port.

[0034] Example:

[0035] See also Figures 1-8 , an atmospheric carbon dioxide concentration monitoring device, comprising a purification box 1, wherein the upper end of the purification box 1 is provided with a guide tube 12, and the inner wall of the guide tube 12 is provided with a filter component 2, through which carbon dioxide is preliminarily filtered;

[0036] Furthermore, the filter assembly 2 includes a fixed cylinder 21 connected to the inner wall of the guide tube 12, the inner cavity of the fixed cylinder 21 is provided with a clamping rod 25, and the lower end of the fixed cylinder 21 is connected to the outlet pipe 28, and the outer surface of the clamping rod 25 is connected to the inner wall of the guide tube 12 through multiple groups of protrusions; the upper end of the clamping rod 25 is provided with a fixed rod 26, the outer surface of the fixed rod 26 is provided with multiple groups of magnetic filter blocks 27, and the multiple groups of magnetic filter blocks 27 are evenly distributed on the outer surface of the fixed rod 26, and the outer surface of the fixed cylinder 21 and above the magnetic filter blocks 27 are connected to a collection pipe 29 for introducing external carbon dioxide into the interior of the fixed cylinder 21;

[0037] In this embodiment, after the carbon dioxide enters the interior of the fixed cylinder 21 through the collection tube 29, the particulate matter in the carbon dioxide is adsorbed by the multiple groups of magnetic filter blocks 27, and the treated carbon dioxide is discharged through the outlet pipe 28 at the lower end of the fixed cylinder 21, and then the treated carbon dioxide is transferred to the interior of the purification box 1 for subsequent operations.

[0038] The outer surface of the clamping rod 25 is provided with multiple groups of protrusions, and the outer surface of the protrusions is connected to the inner wall of the outlet pipe 28. At the same time, a certain gap is reserved between the clamping rod 25 and the inner wall of the outlet pipe 28 to ensure that carbon dioxide can flow smoothly into the purification box 1 through the gap, and cooperate with the guide tube 12 to limit the flow trajectory of carbon dioxide to prevent carbon dioxide leakage.

[0039] Furthermore, the outer surface of the purification box 1 is connected to an air outlet pipe 11 , and a filter plate 13 is provided in the inner cavity of the purification box 1 below the guide pipe 12 , and the outer surface of the filter plate 13 is rotatably connected to the inner wall of the purification box 1 .

[0040] Specifically, the carbon dioxide is filtered twice by the filter plate 13 so that the particulate matter inside the carbon dioxide is removed again, so that the carbon dioxide gas is convenient for subsequent processing after separation, thereby improving the purification efficiency and purification effect.

[0041] Furthermore, a cover plate 22 is provided at the upper end of the fixing cylinder 21 , and an outer surface of a lower end of the cover plate 22 is rotatably connected to an inner wall of the fixing cylinder 21 .

[0042] The outer surface of the fixed cylinder 21 is clamped with a limit block 23, and a positioning rod 24 is rotatably installed on the upper end of the limit block 23. One end of the positioning rod 24 passes through and extends to the other end of the limit block 23, and the lower end of the positioning rod 24 is in contact with the upper end of the cover plate 22.

[0043] Specifically, the fixed cylinder 21 is sealed by the cover plate 22. After a period of filtration, the cover plate 22 can be opened to remove the particles adsorbed therein to ensure normal subsequent filtration.

[0044] At the same time, when the cover plate 22 is fitted with the fixed cylinder 21, the cover plate 22 is fixed by the limit block 23 and the positioning rod 24 to ensure the sealing of the fixed cylinder 21 when filtering is carried out. In addition, rubber and other sealing components are provided at the connection between the cover plate 22 and the fixed cylinder 21 to ensure that the fixed cylinder 21 is isolated from the outside.

[0045] Furthermore, an exhaust assembly 3 is installed in the inner cavity of the purification box 1 and is located below the filter assembly 2 to classify the separated carbon dioxide. The exhaust assembly 3 includes a screw 31 connected to the filter plate 13, and a movable block 32 is threadedly mounted on the outer surface of the screw 31.

[0046] Specifically, after the carbon dioxide is filtered for the first time, it enters the purification box 1 and passes through the -35 degree low-temperature condenser. At this temperature, the carbon dioxide molecules in the carbon dioxide gas are condensed into carbon dioxide when they are cold, reducing the content of carbon dioxide molecules in the carbon dioxide gas, causing the carbon dioxide to move downward and the gas to move upward, and then the gas is discharged through the outlet pipe 11.

[0047] When the carbon dioxide moves downward, it passes through the filter plate 13 and falls into the bottom of the purification box 1. When the carbon dioxide inside the purification box 1 reaches a certain amount, the rubber plug 38 at the lower end is opened to discharge the collected carbon dioxide and perform subsequent operations.

[0048] One end of the screw 31 may be provided with a device with power output, such as a motor, and when the motor is started, the screw 31 is synchronously driven to rotate, so that the movable block 32 can be freely adjusted on the screw 31, making it suitable for different scenarios, and the collected carbon dioxide can be discharged at any time.

[0049] Furthermore, the outer surface of the movable block 32 is provided with multiple groups of connecting blocks 33, and the multiple groups of connecting blocks 33 are evenly distributed on the outer surface of the movable block 32. An adjusting rod 34 is rotatably installed at one end of the connecting block 33 away from the movable block 32, and the outer surface of the adjusting rod 34 is provided with multiple groups of through holes 35.

[0050] Specifically, the connection block 33 can be adjusted to connect with different through holes 35, thereby adjusting the carbon dioxide content inside the purification box 1 for collection under different circumstances. When the connection block 33 is connected to the through holes 35 on both sides, at a relatively high position, the collected carbon dioxide is discharged after the rubber stopper 38 is opened; when the connection block 33 is connected to the through hole 35 in the middle position, at a relatively low position, the carbon dioxide inside the purification box 1 can be discharged.

[0051] Furthermore, an airbag 341 is provided at the upper end of the adjusting rod 34, and a limiting rod 36 is rotatably installed at the lower end of the adjusting rod 34. A fixing plate 37 is provided at the lower end of the screw rod 31, and the lower end of the fixing plate 37 is rotatably connected to the end of the limiting rod 36 away from the adjusting rod 34.

[0052] Specifically, when the carbon dioxide inside the purification box 1 accumulates to a certain height, the airbag 341 drives one end of the adjustment rod 34 to move upward, and then the adjustment rod 34 rotates around the connecting block 33, thereby cooperating with the limit rod 36 to drive the fixing plate 37 to move upward.

[0053] The limiting rod 36 is provided with a sliding groove, the lower end of the fixed plate 37 is provided with an extension block, and the inner wall of the sliding groove is slidably connected to the connection at the lower end of the extension block, and a hole is provided in the middle position of the fixed plate 37, so that when the fixed plate 37 moves upward, it can be limited by the screw rod 31 to ensure the stability of the fixed plate 37 during movement.

[0054] Furthermore, a rubber plug 38 is provided at the lower end of the fixing plate 37 , and the longitudinal section of the rubber plug 38 is in the shape of an inverted trapezoid.

[0055] Specifically, a discharge port is provided at the lower end of the purification box 1, and the inner wall of the discharge port is in contact with the outer surface of the rubber stopper 38, thereby ensuring that the purification box 1 is separated from the outside. At the same time, when the rubber stopper 38 is separated from the discharge port, the carbon dioxide inside the purification box 1 is taken out.

[0056] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
