Description

Technical Field

[0001] This invention belongs to the field of carbon emission monitoring technology, and relates to an industrial site carbon emission monitoring device and its usage method. Background Technology

[0002] With increased environmental regulations and rising demands for carbon emission control in industrial production, carbon emission concentration monitoring has become a crucial task in industrial sites and industrial parks. Currently, infrared absorption spectroscopy is widely used in industrial carbon emission monitoring devices due to its high accuracy and fast response time for detecting greenhouse gases such as carbon dioxide. These devices typically include a detection chamber, an infrared light source, an infrared detector, and filters. The infrared light source emits infrared light of a specific wavelength. After passing through the gas to be monitored within the detection chamber, the infrared light is filtered to remove stray light. The infrared detector receives the optical signal and converts it into an electrical signal, from which the carbon emission concentration is calculated.

[0003] In practical applications, existing industrial carbon emission monitoring devices using infrared absorption methods have several shortcomings. Firstly, after prolonged use, the surfaces of the filters and protective glass protecting the infrared light source are prone to accumulating dust or moisture condensation, which reduces light transmittance and attenuates the light signal received by the infrared detector, directly affecting the accuracy of the detection results. Currently, most devices require periodic manual disassembly of the detection chamber to clean the filters and protective glass. This disassembly process not only involves disconnecting the gas path and disassembling the outer casing, which is time-consuming, but may also alter the relative position of the optical path during disassembly, necessitating recalibration. Furthermore, the device cannot monitor normally during cleaning, affecting the continuity of monitoring work.

[0004] Currently, patent CN222529307U discloses a carbon emission monitoring device that cleans the sensor by setting a rotating ring and a cleaning rod around the sensor. However, in infrared absorption monitoring, the infrared light source and detector are usually located at opposite ends of the detection cavity. If the above-mentioned existing technology is used, a complex cleaning drive mechanism needs to be set at each end, which not only results in a large device size, but also makes the built-in motor or complex gears extremely vulnerable to damage in harsh high-temperature, flammable and explosive industrial airflow environments, leading to extremely high maintenance costs.

[0005] Secondly, the detection chambers of existing devices are mostly integrated structures. When internal transmission components (such as the screw that moves the filter) or seals wear out and require maintenance or replacement, the entire external connecting pipelines and support structure must be disassembled, making the operation cumbersome and maintenance inefficient. Especially in industrial sites, excessive downtime for maintenance can affect the continuous collection of carbon emission data, making it difficult to meet the needs of real-time monitoring. Summary of the Invention

[0006] In view of this, in order to solve the problems of the current industrial carbon emission monitoring devices, such as the need for manual disassembly and cleaning of filters and protective glass after dust accumulation, cumbersome maintenance of the detection chamber, and low efficiency, this invention provides an industrial carbon emission monitoring device and its usage method.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] An industrial site carbon emission monitoring device includes a three-way shaped detection cylinder with a gas channel in the middle and plugs I and II fixed at both ends. An infrared detector is fixedly installed through the top of plug I, and an infrared light source is fixedly installed through the bottom of plug II. A filter body located below the infrared detector body and a transparent glass sheet located above the infrared light source are provided inside the detection cylinder.

[0009] The driving mechanism, located inside the detection cylinder, is used to drive the filter body and the transparent glass sheet to move closer to each other into the gas channel;

[0010] The cleaning component is installed inside the detection cylinder and located between the filter body and the transparent glass sheet. When the filter body and the transparent glass sheet are close together, they come into contact with the cleaning component.

[0011] Two air pumps are used. The air inlet of one air pump is connected to two air inlet pipes through a three-way pipe. The air inlet pipes are connected to the detection cylinder and are used to draw outside air into the gas channel. The exhaust end of the other air pump is connected to an exhaust pipe, which is located inside the gas channel and is used to discharge gas.

[0012] In this process, infrared light emitted by the infrared light source passes through the transparent glass sheet and the gas in the gas channel, is filtered by the filter sheet, and is received by the infrared detection device to detect carbon emission concentration. When the drive mechanism moves the filter sheet and the transparent glass sheet into the gas channel, the airflow discharged from the exhaust pipe drives the cleaning component to automatically clean the surface of the filter sheet and the transparent glass sheet.

[0013] As a further improvement to the above technical solution:

[0014] The testing cylinder includes an upper cylinder and a lower cylinder. The top of the lower cylinder has a mounting groove, and the bottom of the upper cylinder has a plug-in connection part that inserts into the mounting groove. The outer wall of the top of the lower cylinder has a threaded hole, and a fastening screw is threaded through the threaded hole. The fastening screw abuts against the plug-in connection part to fix the upper cylinder and the lower cylinder.

[0015] As a further improvement to the above technical solution:

[0016] The drive mechanism includes two transmission screws, which are respectively rotatably mounted on plug I and plug II through bearings, and their close ends are inserted into each other; rubber frames are slidably provided in both the upper and lower cylinders, and the rubber frames are threaded onto the corresponding transmission screws. A through hole is opened at the top of the rubber frame, and the filter body and transparent glass sheet are respectively embedded in the corresponding through hole.

[0017] A drive motor is fixedly installed on the top of plug I, and the output end of the drive motor is fixedly connected to the corresponding transmission screw.

[0018] As a further improvement to the above technical solution:

[0019] One end of each of the two air intake pipes is located between the reset filter body and the transparent glass sheet, allowing the incoming airflow to sweep the surfaces of the filter body and the transparent glass sheet.

[0020] As a further improvement to the above technical solution:

[0021] The cleaning assembly includes two rotating rings that are rotatably mounted in the mounting groove via bearings. Multiple inclined guide plates are fixed between the two rotating rings. Elastic strips are fixed inside the rotating rings. Cleaning brushes are provided on the opposite sides of the two elastic strips. The cleaning brushes correspond to the filter body and the transparent glass sheet, respectively.

[0022] When the airflow passes through the guide plate, it drives the rotating ring to rotate, causing the cleaning brush to wipe the surface of the filter body and the transparent glass sheet.

[0023] As a further improvement to the above technical solution:

[0024] It also includes a support column, on which an extension rod II is provided. A fixed bracket is fixedly provided on the outer wall of the extension rod II. The upper cylinder is fixedly fixed to the fixed bracket. A protective cylinder is provided on the top of the fixed bracket. The protective cylinder is threaded onto the outer wall of the plug I.

[0025] As a further improvement to the above technical solution:

[0026] A mounting bracket is fixedly installed on the support column, and a control box is fixedly installed on one side of the mounting bracket. The controller inside the control box is connected to the infrared detection device and the infrared light source through wires.

[0027] As a further improvement to the above technical solution:

[0028] Multiple guide strips are fixedly installed inside both the upper and lower cylinders, and the rubber frame is slidably sleeved on the multiple guide strips to restrict the rotation of the rubber frame.

[0029] As a further improvement to the above technical solution:

[0030] An extension rod I is provided on the support column, and a photovoltaic panel is fixedly connected to the top of the extension rod I.

[0031] A carbon emission monitoring method, employing the aforementioned industrial site carbon emission monitoring device, includes the following steps:

[0032] S1. Start the infrared light source and air pump to allow outside air to enter the gas channel through the air intake pipe. The infrared light passes through the gas and is received by the infrared detection device to detect the carbon emission concentration.

[0033] S2. When cleaning is required, the control drive mechanism drives the filter body and the transparent glass sheet to move into the gas channel, and the airflow discharged through the exhaust pipe drives the cleaning component to automatically clean the surface of the filter body and the transparent glass sheet.

[0034] S3. After cleaning is completed, the drive mechanism is reset, and the device continues to monitor.

[0035] The beneficial effects of this invention are as follows:

[0036] 1. The industrial carbon emission monitoring device disclosed in this invention has a built-in cleaning component that can clean the filter body and transparent glass plate without manual intervention. Specifically, the airflow from the exhaust pipe drives the guide plate to rotate the rotating ring. The elastic strip on the rotating ring ensures that the cleaning brush maintains appropriate contact pressure with the surface of the filter body and transparent glass plate, which can effectively wipe away dust without scratching the surface of the components. After each cleaning, the light transmittance of the components can be restored to a high level of the initial state, avoiding the decrease in detection accuracy caused by dust adhesion. Compared with the traditional method of manual periodic disassembly and cleaning, the cleaning process of this device is automatically triggered, without the need to stop the machine or disassemble the detection cylinder, extending the maintenance cycle, reducing the workload and cost of manual maintenance, and improving the efficiency of device use.

[0037] 2. The industrial site carbon emission monitoring device disclosed in this invention comprises an upper cylinder and a lower cylinder. After the upper cylinder is inserted into the mounting groove of the lower cylinder, it can be fixed by fastening screws. During disassembly, the upper and lower cylinders can be separated simply by loosening the screws. This structure facilitates the inspection and replacement of components such as the transmission screw and rubber frame inside the detection cylinder without the need for complete disassembly of the device. Maintenance operations can be completed quickly, significantly reducing maintenance time. It is especially suitable for the need for rapid restoration of the device in industrial sites.

[0038] 3. The industrial site carbon emission monitoring device disclosed in this invention is equipped with two air pumps. The air pump on the intake side is connected to two air intake pipes through a three-way pipe, which can stably draw external air into the detection cylinder to ensure continuous gas renewal in the detection chamber and avoid the lag in detection results caused by gas stagnation. The air pump on the exhaust side works with the exhaust pipe to provide power for the cleaning components, ensuring that the air circuit system can achieve the dual functions of gas renewal and cleaning drive without affecting the real-time performance of the detection process.

[0039] This invention, through the bidirectional convergence of the filter body and the transparent glass plate, and the synergistic cooperation of a centralized pneumatic cleaning mechanism, achieves a significant improvement over the conventional design that requires two separate cleaning mechanisms due to the infrared light source and detector being located at opposite ends. This device utilizes a drive mechanism to move the optical components at both ends towards each other to the center of the gas channel, allowing them to share a single cleaning assembly for synchronous cleaning. This effectively simplifies the internal structure of the detection cylinder and reduces the number of moving parts. Furthermore, after the optical components move to the center, the working airflow from the exhaust pipe directly powers the rotating ring, achieving cleaning while simultaneously renewing the gas in the detection chamber. This avoids the need for an additional electrical drive source inside the detection chamber, improving the inherent safety of the device in industrial settings. In addition, the combination of these structures creates a further synergistic cleaning effect: during the rotation of the airflow-driven cleaning assembly, the elastic strip within the rotating ring periodically contacts the central drive screw, deforming and rebounding to its original position, thus inducing radial oscillation and vibration. This composite cleaning method, which combines flexible brush wiping with high-frequency vibration to overcome obstacles, can effectively remove stubborn dust from the surface of optical components, achieving a deep cleaning effect that is difficult to achieve with single pneumatic rotation or conventional mechanical wiping, and further ensuring the long-term accuracy of carbon emission monitoring data.

[0050] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention.

[0051] like Figure 1The illustrated industrial carbon emission monitoring device comprises a three-way shaped detection cylinder 4 with a gas channel 41 in the middle. The gas channel 41 ensures stable gas flow and effective interaction with infrared light. Plugs I17 and II20, both made of 316L stainless steel, are fixed to both ends of the detection cylinder 4 via threads. Fluororubber O-rings are fitted at the connection points to ensure the airtightness of the detection cylinder 4 and prevent gas leakage from affecting the detection results. An infrared detector 16 is fixed through the top of plug I17. A mounting hole matching the outer diameter of the infrared detector 16 is pre-drilled on plug I17. The infrared detector 16 is fitted into the mounting hole with a tight fit. A layer of thermally conductive silicone grease is evenly coated on the inner wall of the mounting hole to help dissipate heat during operation, maintaining the infrared detector 16's operating temperature within a suitable range. Within this temperature range, the detection accuracy of the infrared detector 16 is highest, and the error can be controlled within a small range. The bottom of the plug II 20 is fixed with an infrared light source 13. The infrared light source 13 is an infrared emitting tube with the characteristic absorption wavelength of carbon dioxide gas, which can accurately capture changes in gas concentration. The plug II 20 is also provided with a mounting hole. After the pin of the infrared light source 13 is led out from the mounting hole, the gap of the mounting hole is filled with epoxy resin sealant to prevent gas leakage and fix the position of the infrared light source 13, so as to avoid the light source shifting during use and affecting the optical path alignment.

[0052] The detection cylinder 4 contains a filter 15 located directly below the infrared detection device 16. The filter 15 is made of calcium fluoride and effectively filters stray light of other wavelengths, improving detection accuracy. A transparent glass plate 21 is located inside the detection cylinder 4 and directly above the infrared light source 13. The transparent glass plate 21 is made of infrared-specific glass (calcium fluoride / zinc selenide), which has high light transmittance and can prevent dust or moisture that may be generated during the detection process from contacting the infrared light source 13, thus providing protection.

[0053] like Figure 2As shown, the two air pumps 8 installed on both sides of the control box are miniature diaphragm air pumps. The air inlet of one air pump 8 is connected to a T-junction via an air pipe. The other two ports of the T-junction are each connected to an air inlet pipe 12. The air inlet pipes 12 are made of PU flexible tubing, which has good flexibility and corrosion resistance. The other ends of the two air inlet pipes 12 are connected to the side walls of the detection cylinder 4, respectively. The connections are secured with pipe clamps and sealed with sealant to prevent air leakage and ensure a stable flow of external air into the detection cylinder 4. When this air pump 8 is working, it can draw external air into the detection cylinder 4 at a stable rate, ensuring continuous gas renewal within the detection cylinder 4 and preventing gas stagnation that could lead to delayed test results. The exhaust end of the other air pump 8 is connected to an exhaust pipe 11 via an air pipe. The exhaust pipe 11 is made of 316L stainless steel, with evenly spaced exhaust holes on its wall. The exhaust pipe 11 is horizontally installed within the gas channel 41, with the exhaust holes facing the inner wall of the gas channel 41.

[0054] The drive mechanism is located inside the detection cylinder 4 and is used to drive the filter body 15 and the transparent glass sheet 21 to move closer together. The drive mechanism includes two drive screws 18, both made of 45# steel with a galvanized surface. One drive screw 18 has a square boss at one end, and the corresponding end of the other drive screw 18 has a square groove that matches the boss. The boss inserts into the groove, enabling the two drive screws 18 to rotate synchronously, preventing slippage and ensuring stable power transmission. The two drive screws 18 are respectively mounted on plug I 17 and plug II 20 through deep groove ball bearings. The inner ring of the bearing is interference-fitted with the drive screw 18, and the outer ring is interference-fitted with the bearing holes on plug I 17 and plug II 20, ensuring smooth rotation of the drive screws 18 without significant jamming and reducing the probability of failure during the drive process.

[0055] like Figure 4As shown, the detection cylinder 4 consists of an upper cylinder 44 and a lower cylinder 42. Both the upper cylinder 44 and the lower cylinder 42 are made of 316L stainless steel. A rubber frame 14 is slidably installed inside both the upper cylinder 44 and the lower cylinder 42. The rubber frame 14 is made of nitrile rubber and is cylindrical in shape. Its outer diameter matches the inner diameter of the detection cylinder 4. An internal thread matching the transmission screw 18 is provided on one side of the center of the rubber frame 14. The frame is threaded onto the corresponding transmission screw 18, ensuring that the transmission screw 18 can drive the rubber frame 14 to move axially when it rotates. A through hole 141 is provided at the top of the rubber frame 14. The diameter of the through hole 141 matches the diameter of the filter body 15 and the transparent glass sheet 21. The filter body 15 and the transparent glass sheet 21 are respectively embedded in the corresponding through holes 141. After embedding, epoxy adhesive is applied to the edges for fixation to prevent them from falling off during use and to ensure that the filter body and the glass sheet move synchronously with the rubber frame 14. The top of the plug I17 is fixed to the drive motor 22 with screws. The output end of the drive motor 22 is fixedly connected to the corresponding transmission screw 18 through a flexible coupling. The flexible coupling can compensate for minor deviations in the transmission process, reduce the impact of vibration on the transmission, and ensure that the power of the drive motor 22 can be smoothly transmitted to the transmission screw 18. When the drive motor 22 is working, it drives the two transmission screws 18 to rotate synchronously, which in turn drives the rubber frame 14 to move along the axial direction of the transmission screws 18, so that the filter body 15 and the transparent glass sheet 21 move closer to each other and finally move into the gas channel 41. At this time, the airflow discharged from the exhaust pipe 11 can act on the surface of the filter body 15 and the transparent glass sheet 21, initially cleaning the dust attached to the surface and preparing for subsequent deep cleaning.

[0056] like Figure 7 The cleaning assembly shown is housed within the detection cylinder 4, located between the filter body 15 and the transparent glass sheet 21. The assembly includes two rotating rings 23, both made of ABS material. These rings are rotatably mounted in the mounting groove 43 at the top of the lower cylinder 42 via thrust ball bearings. The thrust ball bearings can withstand axial force, ensuring the rotating rings 23 rotate freely and reducing resistance during rotation. Multiple inclined guide plates 26, also made of ABS material, are fixed between the two rotating rings 23 by screws. When the airflow from the exhaust pipe 11 passes through the guide plates 26, the airflow exerts a circumferential thrust on the guide plates 26, causing the two rotating rings 23 to rotate synchronously, providing rotational power for the cleaning brush.

[0057] like Figure 5As shown, the inner wall of the rotating ring 23 is fixed with elastic strips 24 by screws. The elastic strips 24 are made of spring steel, possessing good elasticity and adapting to slight undulations in the surfaces of the filter body and glass plate, ensuring the cleaning brush remains in contact with the surface. Cleaning brushes 25 are fixed to the opposite sides of the two elastic strips 24 with adhesive. The bristles of the cleaning brushes 25 are made of nylon, which is soft and wear-resistant, effectively cleaning dust without scratching the surfaces of the filter body and glass plate. When the filter body 15 and the transparent glass plate 21 move closer together into the gas channel 41, the cleaning brushes 25 will contact the surfaces of the filter body 15 and the transparent glass plate 21. The elasticity of the elastic strips 24 ensures that the cleaning brushes 25 maintain appropriate contact pressure with the surface, guaranteeing cleaning effectiveness without damaging the surface. As the rotating ring 23 rotates, the cleaning brush 25 wipes and cleans the surfaces of the filter body 15 and the transparent glass sheet 21. After each cleaning, the light transmittance of the filter body 15 and the transparent glass sheet 21 can be restored to a high level of the initial state, effectively avoiding dust adhesion from affecting the detection accuracy and ensuring the accuracy of the detection data. When the elastic strip 24 touches the transmission screw 18, it will deform until it passes the transmission screw 18. The elastic strip 24 can reset under its own elastic force, generating radial swing and vibration, which can further clean the surfaces of the filter body 15 and the transparent glass sheet 21.

[0058] like Figure 6 As shown, the lower cylinder 42 has a mounting groove 43 at its top, and the upper cylinder 44 has a plug-in connection part 45 at its bottom. After the plug-in connection part 45 is inserted into the mounting groove 43, a threaded hole 46 is formed on the outer wall of the top of the lower cylinder 42. A fastening screw 47 is threaded through each threaded hole 46. After tightening the fastening screw 47, its end abuts against the plug-in connection part 45, fixing the upper cylinder 44 and the lower cylinder 42 together. A graphite sealing gasket is fitted around the inner wall of the mounting groove 43. The sealing gasket ensures the airtightness of the connection between the upper cylinder 44 and the lower cylinder 42, preventing gas leakage from the connection gap. For disassembly, simply loosen the fastening screw 47 with an Allen wrench to remove the upper cylinder 44 from the lower cylinder 42. This facilitates maintenance or replacement of the internal components of the detection cylinder 4, making maintenance simple and convenient, effectively shortening maintenance time and improving the efficiency of the device.

[0059] One end of each of the two air intake pipes 12 is located between the reset filter body 15 and the transparent glass sheet 21. The reset state here means that the drive motor 22 reverses, causing the transmission screw 18 to rotate in the opposite direction, so that the rubber frame 14 returns to its initial position. At this time, the filter body 15 is located on the side closer to the plug I 17, and the transparent glass sheet 21 is located on the side closer to the plug II 20. The ends of the two air intake pipes 12 are exactly between the two. External air enters the gas channel 41 and then flows over the surface of the filter body 15 and the transparent glass sheet 21. This ensures that the gas and infrared light can interact fully to ensure the comprehensiveness of the detection, and also blows away the surface of the filter body 15 and the transparent glass sheet 21 to a certain extent, reducing dust adhesion and reducing the cleaning frequency.

[0060] Multiple guide strips 19, made of stainless steel, are welded and fixed inside both the upper cylinder 44 and the lower cylinder 42. These guide strips are evenly distributed along the axial direction of the detection cylinder 4. The outer wall of the rubber frame 14 has guide grooves that fit the guide strips 19. The rubber frame 14 is slidably fitted onto the guide strips 19 through these grooves. The guide strips 19 restrict the rotation of the rubber frame 14, ensuring that it can only move axially under the drive of the transmission screw 18. This prevents the rubber frame 14 from rotating with the transmission screw 18, thus ensuring the stable position of the filter body 15 and the transparent glass sheet 21, ensuring optical path alignment, effectively guaranteeing detection accuracy, reducing detection errors caused by optical path misalignment, and allowing the rubber frame 14 to clean the inner wall of the detection cylinder 4 during movement.

[0061] The device also includes a support column 1, which is made of Q235 steel. The bottom of the support column 1 is fixed to the ground or mounting platform by multiple expansion bolts. The expansion bolts ensure the stability of the overall device, prevent tipping, and ensure that the device can be placed stably in outdoor or industrial environments. An extension rod II3 is fixed to the support column 1. The extension rod II3 is made of round steel and is fixed to the middle of the support column 1 by welding. A fixing bracket 9 is fixed to the outer wall of the extension rod II3 by screws. The fixing bracket 9 is made of bent steel plate and has fixing holes that match the outer diameter of the upper cylinder 44. The upper cylinder 44 is fixed through the fixing holes. A rubber pad is placed between the inner wall of the fixing holes and the upper cylinder 44 to ensure a stable fixation and reduce the impact of vibration on the detection cylinder 4. Slight vibrations in the industrial environment will not be transmitted to the inside of the detection cylinder 4, avoiding affecting the working stability of the infrared detection device 16 and the infrared light source 13, and ensuring that the detection data is not interfered with by vibration.

[0062] like Figure 3As shown, a protective cylinder 10 is provided on the top of the fixed bracket 9. The protective cylinder 10 is made of ABS material and is cylindrical. Its inner diameter is adapted to the outer diameter of the plug I 17. The protective cylinder 10 is threaded onto the outer wall of the plug I 17. The protective cylinder 10 can completely cover the infrared detector 16 and the drive motor 22, which can play a role in dustproofing and waterproofing, and prevent external dust or rainwater from entering the infrared detector 16 and the drive motor 22 and affecting their service life.

[0063] A mounting bracket 5, made of steel plate, is bolted to the support column 1. A control box 6, made of cold-rolled steel plate and coated with epoxy resin powder for rust prevention, is fixed to one side of the mounting bracket 5 with screws. Inside the control box 6 is a controller connected to the infrared detector 16 and infrared light source 13 via wires. The wires exit through a wiring hole on the side of the control box 6, with a waterproof connector installed inside to ensure the control box 6 is airtight and prevent rainwater or dust from entering and affecting the controller's operation. An LCD screen is embedded in the front of the control box 6, displaying the detected carbon emission concentration data and the device's operating status, such as the air pump and drive motor status, allowing operators to monitor the device's operation in real time.

[0064] One side of the control box 6 is integrally formed with a side box 61. The side box 61 can hold spare sealing rings, screws, and other small parts for easy access during maintenance, preventing maintenance interruptions due to missing parts. A protective cover 62, made of transparent acrylic, is snapped onto the side box 61. Opening the cover allows access to internal parts, while closing it prevents parts from being lost or exposed to moisture, ensuring the integrity of spare parts. Both air pumps 8 are housed within the control box 6. Two air pump mounting brackets are fixed inside the control box 6 with screws. Rubber shock-absorbing pads are placed between the air pump mounting brackets and the air pumps 8 to reduce the transmission of vibrations generated by the air pumps 8 during operation to the control box 6, lowering the overall noise level of the device and ensuring that the noise level meets industrial environment requirements, preventing noise interference to the surrounding environment.

[0065] An extension rod I2, made of round steel, is bolted to the support column 1. A photovoltaic panel 7, made of monocrystalline silicon, is fixed to the top of the extension rod I2 via a bracket. The bracket is adjustable, allowing for tilting of the photovoltaic panel 7 according to the latitude of the testing site to maximize solar energy absorption and improve solar energy utilization. The photovoltaic panel 7 is connected to a battery inside the control box 6 via wires. In the presence of sunlight, the photovoltaic panel 7 charges the battery, which powers the drive motor 22, air pump 8, controller, and infrared light source 13, enabling offline operation of the device. This is suitable for outdoor testing scenarios without mains power. In the absence of sunlight or with insufficient sunlight, the battery can be charged via an external mains power supply through the charging interface on the back of the control box 6, ensuring continuous operation and normal operation in various environments.

[0066] In practical use, the industrial site carbon emission monitoring device first fixes the support column 1 at the testing site, adjusts the angle of the photovoltaic panel 7 to the optimal lighting position, and then connects the wires of each component to ensure that the controller can properly control the operation of each component. After starting the device, the controller controls the infrared light source 13 to turn on and simultaneously controls the air pump 8 on the air intake side to work, drawing external air into the detection cylinder 4 through the air intake pipe 12. The air enters the gas channel 41 and flows through the filter body 15 and the transparent glass plate 21. The infrared light emitted by the infrared light source 13 passes through the transparent glass plate 21 and the air in the gas channel 41, and after being filtered out by the filter body 15 to remove stray light, it is received by the infrared detection device 16. The infrared detection device 16 converts the light signal into an electrical signal and transmits it to the controller. The controller calculates the carbon emission concentration in the air according to the Lambert-Beer law and displays it on the LCD screen. The detection data is updated regularly to ensure that the carbon emission situation at the testing site is reflected in real time, providing timely data support for environmental monitoring. After the device has been working continuously for a period of time, the controller will automatically trigger the cleaning program, control the drive motor 22 to work, drive the transmission screw 18 to rotate, so that the rubber frame 14 moves the filter body 15 and the transparent glass sheet 21 closer to each other and into the gas channel 41. At the same time, the controller controls the exhaust side air pump 8 to work, and discharges the gas in the gas channel 41 through the exhaust pipe 11. When the airflow passes through the guide plate 26, it drives the rotating ring 23 to rotate. The rotating ring 23 drives the elastic strip 24 and the cleaning brush 25 to rotate. The cleaning brush 25 wipes and cleans the surface of the filter body 15 and the transparent glass sheet 21. After the cleaning process lasts for a certain period of time, the controller controls the drive motor 22 to reverse, so that the filter body 15 and the transparent glass sheet 21 are reset, the exhaust side air pump 8 stops working, and the device resumes normal detection, ensuring that the device can maintain high detection accuracy even after long-term operation.
