Description

Technical Field

[0001] The present invention relates to the technical field of carbon accounting, and in particular to an emission monitoring system and a carbon accounting method for carbon accounting. Background Art

[0002] As global attention to climate change continues to increase, reducing greenhouse gas emissions has become an important issue for governments and companies. Carbon accounting, as a process of evaluating the greenhouse gas emissions of an organization or project over a specific period of time, is essential for developing effective emission reduction strategies. Accurate and reliable carbon accounting data not only helps companies understand their own carbon footprint, but also provides a basis for government policy making and supports the international community's efforts to address climate change.

[0003] However, in the existing carbon accounting practice, there are many challenges that affect the accuracy and reliability of the data. First, traditional carbon emission monitoring systems rely heavily on manual sampling and laboratory analysis, which is inefficient and prone to human errors. Secondly, although online monitoring systems with a high degree of automation can collect data in real time, dust is easily accumulated on the surface of the sensor during long-term operation of the equipment, resulting in a decrease in measurement accuracy, which in turn affects the accuracy of carbon emission calculation results. In addition, there is a lack of an effective cleaning mechanism in the data processing stage, and outliers and malformed data are not fully removed, which may cause the final generated carbon accounting report to be biased. Therefore, an emission monitoring system and carbon accounting method for carbon accounting are needed to solve the above problems. Summary of the invention

[0031] 1.

The data verification module then verifies the processed data by comparing horizontally with similar companies in the same industry and vertically with the company's own historical data.

The bristles on the cleaning rod can wipe off the carbon ash attached to the surface of the carbon dioxide concentration sensor and the temperature sensor. This automatic cleaning function effectively prevents the problem of decreased detection accuracy due to dust accumulation on the sensor, ensures that the sensor can continuously and accurately collect exhaust data, maintains the stable operation of the entire monitoring system, and reduces accounting deviations and maintenance costs caused by equipment failure or inaccurate detection.

[0033] 3.

[0060] The cleaning mechanism 3 includes a dust-proof cylinder 301, a stretching rod 302 and a cleaning rod 303. The dust-proof cylinder 301 is installed in the measuring tube 102 and is rotatably connected thereto. A storage groove 3011 is provided on the side of the dust-proof cylinder 301.

[0061] The knocking mechanism 4 includes a knocking frame 401 and a rotating disk 402 matched therewith, and the knocking frame 401 is fixedly installed on the top of the inner end surface of the measuring tube 102;

[0062] The driving mechanism 5 includes a driving motor 501, a first driving shaft 502, a planetary reducer 503, a second driving shaft 504 and a fixed frame 505. The driving motor 501 is fixedly installed in the measuring tube 102. The first driving shaft 502 is fixedly installed on the output shaft of the driving motor 501.

The dustproof cylinder 301 is fixedly installed on the first driving shaft 502. The turntable 402 is fixedly installed on the top of the second driving shaft 504.

[0063] Furthermore, a first rotating shaft 3012 is fixedly installed on the top of the side end surface of the storage groove 3011, a first ear plate 3021 rotatably matched with the first rotating shaft 3012 is provided on the top of the extension rod 302, a second ear plate 3022 is provided on the bottom of the side end surface of the extension rod 302, a second rotating shaft 3032 rotatably matched with the second ear plate 3022 is provided on the bottom of the cleaning rod 303, and bristles 3031 for cleaning the carbon dioxide concentration sensor 203 and the temperature sensor 204 are provided on the cleaning rod 303.

[0064] When the driving motor 501 drives the dustproof cylinder 301 to rotate at high speed, the extension rod 302 and the cleaning rod 303 will expand outward under the action of centrifugal force, so that the cleaning bristles 3031 will contact the carbon dioxide concentration sensor 203 and the temperature sensor 204, thereby wiping off the carbon ash attached to their surface and improving the detection accuracy.

[0065] Furthermore, an inner end surface of the extension rod 302 is provided with a shaft seat 3023, a rotatably connected transmission shaft 304 is provided on the shaft seat 3023, a second gear umbrella 3013 is provided on the first rotating shaft 3012, a first gear umbrella 3041 meshing with the second gear umbrella 3013 is provided on the top of the transmission shaft 304, a third gear umbrella 3042 is provided on the bottom of the transmission shaft 304, a fourth gear umbrella 3024 meshing with the third gear umbrella 3042 is provided on the second rotating shaft 3032, and a limiting groove 3014 for limiting the rotation angle of the extension rod 302 is provided on the top of the storage groove 3011.

[0066] The cleaning rod 303 is unfolded together with the stretching rod 302 under the action of centrifugal force through the transmission shaft, and when the driving motor 501 stops rotating, the cleaning rod 303 can fall back and fold inward into the storage groove 3011 together with the stretching rod 302 under the action of gravity, thereby preventing the cleaning rod from being contaminated by the airflow and dust in the exhaust pipe 101, thereby improving its brushing effect. The limiting groove 3014 accurately limits the angle of the cleaning rod 303, so that when the stretching rod 302 is unfolded to the maximum angle, the bristles 3031 are accurately in contact with the carbon dioxide concentration sensor 203 and the temperature sensor 204.

[0067] Furthermore, the knocking frame 401 includes a base 4011, a knocking plate 4012 and a torsion spring 4013, a third ear plate 40112 is arranged on the side of the base 4011, a third rotating shaft 40123 rotatably matched with the third ear plate 40112 is arranged on the knocking plate 4012, the torsion spring 4013 is sleeved on the third rotating shaft 40123, the knocking plate 4012 is elastically rotatably connected with the base 4011 through the torsion spring 4013, a supporting block 40111 is arranged on the side of the base 4011, a knocking block 40121 matched with the supporting block 40111 is arranged on the knocking plate 4012, a guide groove 40124 is arranged at the end of the knocking plate 4012 away from the knocking block 40121, a pressure plate 4021 slidably matched with the guide groove 40124 is arranged on the turntable 402, and the pressure plate 4021 is a rounded rectangular structure.

[0068] The turntable 402 is driven to rotate slowly by the second driving shaft 504, so that the pressure plate 4021 squeezes the guide grooves 40124 of each knocking plate 4012 in turn, so that the knocking block 40121 and the supporting block 40111 are gradually separated. When the pressure plate 4021 passes over the guide groove 40124, the knocking plate 4012 is quickly reset under the action of the torsion spring 4013, so that the knocking block 40121 hits the supporting block 40111 to knock it, and drives the measuring tube 102 to shake, thereby shaking off the dust attached to the inside.

[0069] Furthermore, the dust cover 103 is a conical corrugated tube structure, an annular groove 1022 is provided at the bottom of the outer end surface of the measuring tube 102, the number of the knocking frames 401 is three, and the number of the pressure plates 4021 is two.

[0070] The annular groove 1022 is used to reduce the bottom stiffness of the measuring tube 102, thereby increasing the swing amplitude of the measuring tube 102 when it is hit, and the dust cover 103 is used to prevent dust from falling in the interlayer between the measuring tube 102 and the exhaust pipe 101, while not affecting the swing of the measuring tube 102. The number of pressure plates and knocking frames 401 is not equal, so that the pressure plate knocks on each knocking frame 401 in turn, avoiding energy cancellation caused by simultaneous knocking, reducing the vibration amplitude of the measuring tube 102, and affecting the dust removal effect.

[0071] When the data acquisition device is in use, the tail gas pipe 101 of the equipment installation tube 1 is connected to the tail gas emission pipeline that needs to monitor carbon emissions, ensuring that the connection is tight and there is no gas leakage, so that the tail gas can pass through the measuring tube 102 smoothly, start the entire emission monitoring system, and the data acquisition device starts working. The flow rate sensor 202, the carbon dioxide concentration sensor 203 and the temperature sensor 204 collect the flow rate, carbon dioxide concentration and temperature data of the tail gas in the measuring tube 102 in real time, and transmit these data to the controller 201. After the system has been running for a period of time, the driving motor 501 of the cleaning mechanism 3 is started, and the driving motor 50 The first driving shaft 502 is driven to rotate, thereby driving the dust-proof cylinder 301 to rotate at a high speed. Due to the effect of centrifugal force, the extension rod 302 installed in the storage groove 3011 of the dust-proof cylinder 301 will be expanded outward around the first rotation axis 3012, and the cleaning rod 303 at the bottom of the extension rod 302 will also be expanded around the second rotation axis 3032 under the coordinated effect of the transmission shaft 304, the toothed umbrella and the centrifugal force, so that the bristles 3031 on the cleaning rod 303 are in contact with the carbon dioxide concentration sensor 203 and the temperature sensor 204. As the dust-proof cylinder 301 continues to rotate at a high speed, the bristles 3031 continuously wipe the carbon ash attached to the sensor surface. Thereby improving the detection accuracy of the sensor and ensuring that the collected data is accurate and reliable, when the driving motor 501 is running, the power is transmitted to the second driving shaft 504 after being decelerated and torque-increased by the planetary reducer 503, driving the turntable 402 to rotate slowly, and the pressure plate 4021 on the turntable 402 squeezes the guide grooves 40124 on each knocking frame 401 in turn as the turntable 402 rotates, so that the knocking plate 4012 rotates around the third rotating shaft 40123, and the knocking block 40121 and the supporting block 40111 gradually separate, and the torsion spring 4013 is stretched to store energy. When the pressure plate 4021 passes over the guide groove 40124, The knocking plate 4012 is quickly reset under the restoring force of the torsion spring 4013, and the knocking block 40121 hits the supporting block 40111, generating an impact force, driving the measuring tube 102 to shake, thereby shaking off the dust attached to the inside of the measuring tube 102, keeping the inside of the measuring tube 102 clean, and preventing dust from interfering with data collection. When the cleaning work is completed, turn off the drive motor 501, and the extension rod 302 and the cleaning rod 303 will fall back under the action of gravity and fold inward into the storage groove 3011, avoiding the cleaning rod from being exposed to the exhaust pipe 101 for a long time and being contaminated by airflow and smoke, thereby preparing for the next cleaning work.

[0072] Example 2

[0073] See also Figure 1-Figure 12 , a method for using an emission monitoring system for carbon accounting, comprising the following steps:

[0074] Step 1: Data collection: collect the carbon dioxide concentration, temperature and exhaust gas flow rate in the exhaust gas through the data collection device in the data collection module, establish a secure data connection interface with the enterprise resource management system ERP, and use data extraction tools to extract raw material purchase volume and product output data from the database of the ERP system according to a preset schedule.

[0075] Step 2: Data transmission. The data transmission module transmits the raw data collected in step 1 to the data processing module. If a wired method is used, such as Ethernet connection, an industrial-grade Ethernet switch and shielded twisted pair cable are used to ensure the stability and anti-interference ability of data transmission. If a wireless transmission method is used, select a suitable wireless communication technology, 4G / 5G network or industrial wireless LAN.

[0076] Step 3, data processing. The data processing module cleans the raw data passed in step 2. For the collected data on carbon dioxide concentration, temperature, flow rate, raw material purchase volume and product output, the deviation percentage of each data point from the mean of the data sequence is calculated. If the deviation exceeds the threshold, it is judged as an outlier and corrected or directly deleted using the moving average method or median filter method. The cleaned data is then converted and analyzed and calculated. The carbon dioxide emissions are calculated using the emission factor method. For data with incorrect formats, such as data type mismatch and string format error, the data verification program is used to identify and correct them. For example, if a data should be a numeric type but is mistakenly recorded as a string, the program will try to convert it to the correct numeric type. If the conversion fails, the data is marked as erroneous data, and the average value of historical data, interpolation of adjacent data or other reasonable methods are selected to supplement it according to the importance and missingness of the data.

[0077] Convert data in different units into standard units, such as converting the units of raw material purchase quantity into kilograms or tons, and converting the units of flow rate into standard cubic meters per second (Nm). 3 / s, etc., so as to perform accurate calculations and analysis in subsequent calculations. For time series data, the acquisition timestamp is converted into a unified time format such as UTC time to facilitate time series analysis of the data and synchronization with other systems;

[0078] First, establish the company's energy consumption list. According to the raw material purchase volume and product output data, combined with the production process and energy consumption model, determine the types and quantities of energy consumed in different production links. For each energy source, query the corresponding emission factor database to obtain its carbon dioxide emission factor per unit energy consumption, and calculate the carbon dioxide emissions of each energy source according to the following formula: E C02 =Q×EF, where E C02is the carbon dioxide emissions, Q is the energy consumption, EF is the emission factor, and the carbon dioxide emissions of all energy sources are added together to obtain the total carbon dioxide emissions of the enterprise.

[0079] Step 4: Data verification: Establish a carbon emissions database for enterprises in the same industry, screen them based on factors such as enterprise scale, production process, and product type, collect carbon emissions data from similar enterprises in the same industry, and update them regularly. Calculate the difference and ratio between the enterprise's carbon emissions data and the average carbon emissions, median carbon emissions, and carbon emissions of advanced enterprises in the same industry. Use statistical hypothesis testing methods such as t-tests or variance analysis to determine whether there are significant differences between the enterprise's data and data in the same industry. Extract carbon emissions data for a period of time in the past, such as the past year or the past three years, from the enterprise's historical carbon emissions data repository. Establish a time series model such as an ARIMA model or a simple linear regression model to predict the carbon emissions range of the enterprise under current production conditions. Compare the currently calculated carbon emissions with the predicted values ​​of historical data. If the deviation exceeds the preset threshold, conduct an in-depth analysis of the factors that lead to changes in carbon emissions, which may include improvements in production processes, substitution of raw materials, implementation of energy efficiency improvement measures, changes in production scale, etc., so that enterprises can understand the changing trends of their own carbon emissions and the effectiveness of energy conservation and emission reduction efforts.

[0080] Step 5. Generate a report. The report generation module generates a carbon accounting report according to the preset report template based on the carbon accounting data verified by the data verification module. The report generation module obtains the verified carbon accounting data from the data verification module according to the template requirements and fills it into the corresponding position of the report template.
