Description

Technical Field

[0001] This utility model relates to the technical field of carbon dioxide measuring devices, and in particular to a high-precision carbon dioxide measuring device for stationary pollution sources. Background Technology

[0002] With the acceleration of industrialization, environmental pollution has become increasingly serious, especially the emission of greenhouse gases such as carbon dioxide, which has had a profound impact on the global climate. Therefore, high-precision measurement of carbon dioxide emissions from stationary pollution sources (such as factories and power plants) has become an important part of environmental protection and climate governance. The development and application of high-precision carbon dioxide measurement devices for stationary pollution sources are of great significance for monitoring and controlling greenhouse gas emissions and promoting green and sustainable development.

[0003] Existing carbon dioxide measurement devices have low accuracy. For industrial sites requiring strict monitoring of carbon dioxide emissions, such as chemical plants and power plants, low accuracy will fail to accurately reflect actual emissions, potentially leading to enterprises being unable to detect and control excessive emissions in a timely manner, thus increasing the risk of environmental pollution. Meanwhile, in the scientific research field, accurate carbon dioxide measurement data is crucial for studying climate change and ecosystem responses. Low accuracy of the measurement device will affect the accuracy and reliability of research data, potentially impacting the correctness of research conclusions. Therefore, we propose a high-precision carbon dioxide measurement device for stationary pollution sources. Utility Model Content

[0015] This invention provides a high-precision carbon dioxide measurement device for stationary pollution sources, which has the following advantages compared with the prior art:

[0016] 1. This design presents a high-precision carbon dioxide measurement device for stationary pollution sources. By adopting a high-precision carbon dioxide measurement device, it can more effectively and accurately monitor organized carbon dioxide emissions in real time, thereby improving the efficiency of daily supervision and operation. At the same time, it supports the "dual carbon" work, carries out carbon dioxide monitoring of stationary pollution sources, and builds a carbon dioxide monitoring quality control system.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0032] Please see Figure 1-7 This utility model provides a technical solution for a high-precision fixed pollution source carbon dioxide measurement device: a high-precision fixed pollution source carbon dioxide measurement device includes a carbon dioxide measurement device 1, an organic box 101 installed inside the carbon dioxide measurement device 1, a flue gas sampler 3, a heat tracing pipe 2 connecting the carbon dioxide measurement device 1 and the flue gas sampler 3, and a backflushing device 4, the output pipe of the backflushing device 4 extending to the flue gas sampler 3.

[0033] A touch screen 102 is installed on the outside of the chassis 101. A flow meter 103 is fixedly installed on the outside of the chassis 101. A power switch 104 is fixedly installed on the outside of the chassis 101. A network port 105 is provided on the chassis 101. Multiple DB9 serial ports 106 are provided on the chassis 101 at equal intervals, and the multiple DB9 serial ports 106 are located on one side of the network port 105. A DB25 parallel port 107 is provided on the chassis 101, and the DB25 parallel port 107 is located on one side of the DB9 serial port 106. A pipe connector 108 is fixedly installed on the chassis 101, and the other end of the pipe connector 108 extends into the chassis 101. A high-precision carbon dioxide measurement module 109 is installed inside the chassis 101. Two spaced-apart switching power supplies 110 are fixedly installed on the chassis 101.

[0034] The device adopts a 19-inch chassis structure, measuring 482.6 (W) x 450 (D) x 177 (H) mm, and is made of aluminum plate. It uses a 7-inch embedded touchscreen (capacitive screen) as the human-machine interface for daily operation. The device employs advanced dual-beam non-dispersive infrared (NDIR) detection technology, allowing for range switching between 0–10 / 20 / 100% based on the target concentration at the site. Measurement repeatability is ≤2.0%, and drift is ≤±2%FS. The device includes a flow meter 103 with a flow rate range of 0.5–2 L / min, enabling real-time flow monitoring. It is equipped with a network port 105, a DB9 serial port 106, and a DB25 parallel port 107 to meet multi-channel data transmission requirements. By employing a high-precision carbon dioxide measurement device, it enables more effective and accurate real-time monitoring of organized carbon dioxide emissions, improving the efficiency of daily monitoring and operation.

[0035] This utility model adopts advanced infrared detection technology, which can be referenced. Figure 7 As shown, when infrared light passes through the gas cell, the gas molecules absorb infrared light of a specific wavelength, and the absorption relationship follows Beer-Lambert law. By measuring the light intensity of the absorption window and the non-absorption window, the concentration of the gas can be calculated. Two optical filters are installed on the detector surface. One filter is selected to allow infrared light specific to carbon dioxide to pass through (the measurement filter), and the second filter is the reference filter. Light of wavelengths not absorbed by carbon dioxide passes through the reference filter. The difference in light intensity between the two filters provides the energy (light intensity) absorbed by carbon dioxide. The signal generated by the sensor is nonlinear. This signal is sent to the MCU of the carbon dioxide sensor module, where it is linearized in the circuit, and the carbon dioxide concentration is converted into digital and analog outputs.

[0036] The chassis 101 is made of high-strength, corrosion-resistant alloy material, with a nickel alloy plating on its surface. The use of this high-strength alloy material significantly improves the chassis's mechanical strength and impact resistance, enabling it to withstand physical pressure in harsh working environments, extending the equipment's service life, and enhancing its corrosion resistance to ensure the internal electronic components are not damaged. The pipe connector 108 uses an O-ring seal structure and a quick-connect connection, facilitating easy connection and disassembly of the sampling pipeline. The O-ring seal effectively prevents gas leakage during sampling, ensuring accurate measurement results. The quick-connect connection greatly simplifies the connection and disassembly process, improving work efficiency. The backflushing device 4 is equipped with a pressure regulating valve, which controls the pressure and flow rate of the backflushing gas, ensuring optimal backflushing performance. This helps prevent blockage of the sampling pipe and keeps the measurement system unobstructed. The heat tracing pipe 2 is wrapped with high-efficiency insulation material and contains a built-in heating cable. The high-efficiency insulation material effectively reduces heat loss, ensuring the temperature inside the heat tracing pipe remains within the set range and preventing condensation of the sampling gas inside the pipe, which could affect the measurement results. The heating effect of the heating cable keeps the temperature inside the heat tracing pipe constant, avoiding measurement errors caused by temperature changes and improving the stability and reliability of the measurement results.

[0037] Please see Figure 8-11 The chassis 101 has an installation port for installing the touch screen 102. The touch screen 102 is placed into the installation port. Two spaced slots 5 are fixedly installed on the chassis 101. The touch screen 102 has sliding grooves 6 on both sides. A sliding limit block 7 is inserted into the sliding groove 6. One end of the limit block 7 can be inserted into the slot 5. A spring 8 is provided in each sliding groove 6. The two ends of the spring 8 are fixedly connected to the touch screen 102 and the limit block 7, respectively.

[0038] The touchscreen 102 is installed using a connection method involving the limiting block 7 and the slot 5. The touchscreen 102 is designed for easy installation and removal, making the process simpler and faster. Over time, dust or dirt may accumulate on the touchscreen 102, requiring regular cleaning. The easy-to-install design facilitates cleaning, ensuring the cleanliness and lifespan of the touchscreen 102. When the touchscreen 102 malfunctions, the easy-to-install design allows for quick replacement of the faulty component, reducing downtime and improving the overall reliability and availability of the equipment.

[0039] A sealing strip 14 is provided on the inner side of the mounting opening for installing the touch screen 102, which can improve the sealing between the touch screen 102 and the chassis 101. Several equally spaced heat dissipation slots 9 are provided on the touch screen 102, which are connected to the internal cavity of the touch screen 102 and are inclined. By setting the heat dissipation slots 9, the heat dissipation efficiency of the internal electrical components of the touch screen 102 is accelerated. At the same time, the inclined arrangement of the heat dissipation slots 9 allows dust to slide out, preventing dust accumulation inside the heat dissipation slots 9.

[0040] A protective cover 10 is fixedly installed on the touch screen 102. The protective cover 10 is located outside multiple heat dissipation slots 9. Inside the protective cover 10 is a miniature air pump 11 fixedly connected to the touch screen 102. The exhaust end of the miniature air pump 11 is connected to and fixedly installed with an exhaust pipe 12. The exhaust pipe 12 has multiple ports, which are located at both ends of the heat dissipation slots 9 and face the heat dissipation slots 9. Valves 13 are installed at both ends of the exhaust pipe 12. The miniature air pump 11 is started at regular intervals, and the miniature air pump 11 pumps airflow into the exhaust pipe 12. The airflow is discharged from the ports of the exhaust pipe 12 and passes through the ports of the heat dissipation slots 9. A rapid airflow flows through the ports of the heat dissipation slots 9, and under the action of air pressure, the dust in the heat dissipation slots 9 can be discharged.
