[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0028] Please refer to Figures 1-4 , the intelligent monitoring system for greenhouse gas emission intensity, including a monitoring box 1. The monitoring box 1 serves as the core carrier and internally integrates functional modules such as cooling, detection, and data processing. An intake pipe 2 and an exhaust pipe 3 are respectively connected to both sides of the monitoring box 1, and the intake pipe 2 and the exhaust pipe 3 are respectively connected to the exhaust passage through connectors.
[0029] In this embodiment, the monitoring box 1 integrates the functions of intake, cooling, detection, and exhaust, with a compact structure and convenient installation and maintenance. It is docked with the exhaust passage through standardized connectors, applicable to high-temperature exhaust scenarios in different industries such as chemical industry and forging, without the need to modify the existing exhaust pipe structure, reducing the installation complexity.
[0030] A cooling component 4 is arranged in the monitoring box 1. The intake pipe 2 is communicated with the cooling component 4. The cooling component 4 is used to cool the incoming gas, eliminate the influence of high temperature on the accuracy of the detection equipment, and extend the service life of the equipment. One end of the cooling component 4 away from the intake pipe 2 is communicated with a monitoring pipe 5. A greenhouse gas detector 6 (such as a CO2, CH4 sensor) is arranged on the monitoring pipe 5. The sensor of the greenhouse gas detector 6 extends into the monitoring pipe 5, and the exhaust pipe 3 is communicated with the monitoring pipe 5.
[0031] In this embodiment, the high-temperature gas is pre-treated by the cooling component 4, effectively reducing the temperature of the gas entering the monitoring tube 5, avoiding the direct impact of high temperature on the greenhouse gas detector (such as CO2, CH4 sensors), and significantly reducing the risk of performance attenuation or damage of the sensors caused by thermal stress. After cooling, the gas temperature tends to be stable, reducing the impact of temperature fluctuations on the sensitivity of the sensors, thereby improving the data accuracy. The greenhouse gas detector 6 detects the gas concentration and composition in real time to ensure data accuracy and provide a reliable basis for environmental protection decision-making.
[0032] A control box is provided on the monitoring box 1. A processor 7 and a communication module 8 are installed in the control box. Both the greenhouse gas detector 6 and the communication module 8 are signal-connected to the processor 7. The communication module 8 is signal-connected to the cloud server or the local terminal. The real-time data is uploaded to the cloud server or the local terminal through the communication module 8 to realize the remote collaborative supervision of enterprises and environmental protection departments, and support the backtracking of historical data and the analysis of emission trends.
[0033] In this embodiment, the greenhouse gas detector 6 combines with the processor 7 to realize the real-time analysis of the gas concentration and composition, and synchronizes the data to the cloud or the local terminal through the communication module 8, supporting remote monitoring and instant warning, and meeting the timeliness requirements of carbon emission supervision.
[0034] Among them, as Figure 3 、 4 shown, the cooling component 4 includes a cooling shell 41. The two sides of the cooling shell 41 are respectively communicated with the intake pipe 2 and the monitoring tube 5. A number of evenly distributed thermoelectric coolers 42 are provided on the outer wall of the cooling shell 41. The cold ends of the thermoelectric coolers 42 extend into the cooling shell 41, and the thermoelectric coolers 42 can quickly cool the gas. Baffles 43 are alternately arranged up and down in the cooling shell 41, and the baffles 43 form a serpentine channel inside the cooling shell 41. The alternate arrangement of the baffles 43 maximizes the heat exchange area in a limited space. The gas turbulent flow effect enhances the boundary layer destruction, and the heat exchange efficiency is increased by more than 50% compared with the straight-through structure, while avoiding additional energy consumption. It should be noted that the evenly distributed thermoelectric coolers 42 allow the number to be flexibly increased or decreased according to the cooling requirements, and the spacing of the baffles 43 in the serpentine channel can also be adjusted to adapt to different gas flows, and the design has good working condition adaptability.
[0035] In this embodiment, the rapid cooling of the thermoelectric coolers 42 is combined with the passive heat dissipation of the serpentine channel. The cold end directly contacts the gas to achieve instantaneous cooling, and the tortuous path formed by the baffles 43 prolongs the gas heat exchange time. The two cooperate to effectively reduce the gas temperature and improve the detection accuracy.
[0036] Furthermore, a temperature sensor 44 is provided in the cooling shell 41 and near the intake pipe 2 to real-time monitor the temperature of the gas entering the inside of the cooling shell 41 and send the detected data to the processor 7, and the processor 7 controls the thermoelectric coolers 42.
[0037] The inlet temperature sensor 44 and the processor 7 form a closed-loop feedback to adjust the power of the semiconductor refrigeration chip in real time, avoiding overcooling or insufficient cooling, especially adapting to scenarios with fluctuations in flow rate or inlet temperature, and improving the system response speed and energy efficiency ratio.
[0038] In addition, an air extraction mechanism 9 is provided inside the monitoring box 1 and near the air outlet pipe 3. The monitoring pipe 5 is connected to the intake end of the air extraction mechanism 9, and the air outlet pipe 3 is connected to the exhaust end of the air extraction mechanism 9. The air extraction mechanism 9 serves as the power source for gas flow, actively extracts and directs the flow of the gas discharged into the exhaust passage, thereby enabling the monitoring system to better monitor the discharged gas. A one-way valve 10 is provided on the air outlet pipe 3 to prevent gas backflow.
[0039] In this embodiment, through the active drive of the air extraction mechanism 9, after the gas enters from the intake pipe 2, it is cooled by the cooling component 4, then quickly passes through the monitoring pipe 5, and finally is discharged from the air outlet pipe 3, reducing the lag of traditional passive diffusion and improving the real-time monitoring ability.
[0040] Furthermore, the communication module 8 is one of a 4G / 5G module, a Wi-Fi module, or a LoRa wireless transmission module. A power supply module 11 is provided inside the control box to provide power support for the system. Solar power supply is optional to reduce energy consumption and is suitable for long-term monitoring in the wild or industrial environments. An alarm module 12 is provided outside the monitoring box 1, and the processor 7 is signal-connected to the alarm module 12. When the detected concentration of greenhouse gas exceeds the preset threshold, an alarm signal is triggered.
[0041] Working principle:
[0042] Gas collection and cooling: The gas to be measured enters the cooling housing 41 through the intake pipe 2, and the semiconductor refrigeration chip 42 quickly cools the gas. The serpentine baffle 43 extends the gas flow path to ensure sufficient cooling.
[0043] Gas detection: The cooled gas enters the monitoring pipe 5, and the greenhouse gas detector 6 analyzes the concentration of gases such as CO2 and CH4. The air extraction mechanism 9 assists the gas to enter the monitoring box 1.
[0044] Data processing and transmission: The processor 7 receives the detection data and uploads it to the cloud server or local terminal through the communication module 8. If the gas concentration exceeds the standard, the alarm module 12 triggers a warning signal.
[0045] Gas discharge: The detected gas is discharged back into the exhaust passage through the air outlet pipe 3 for subsequent processing, and the one-way valve 10 prevents gas backflow.
[0046] The above are only the preferred specific embodiments of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and its improvement concept of the present invention, making equivalent substitutions or changes should be covered by the protection scope of the present invention.
