[0002] The cement industry is one of the important sources of carbon emissions, and the carbon dioxide produced in its production process has a significant contribution to global warming. Determining the carbon emissions of the cement industry helps to accurately assess its potential impact on global climate change and provide a scientific basis for developing effective response strategies.

[0003] Currently, the carbon emissions of the cement industry are generally evaluated by accounting methods, which specifically involve calculating the carbon emissions of fuel consumption and production processes by statistical process data such as fuel consumption and product output, and according to certain emission factors. If the cement enterprise uses non-carbonate substitutes for raw materials, it also needs to deduct according to the corresponding deduction coefficient of different substitute raw materials. Since the emission factor mainly uses the default value (i.e. the empirical value) in the accounting guide rather than the measured value, the accounting results of carbon emissions have a large degree of uncertainty.

[0052] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0053] This invention discloses a carbon emission monitoring device, method, system, and data processing equipment. By deploying the carbon emission monitoring device at the exhaust outlet of a cement clinker production facility, it achieves full-process, real-time, and traceable monitoring of key parameters in the emitted flue gas. The carbon emission monitoring device adopts a multi-sensor collaborative monitoring architecture, simultaneously collecting data on carbon dioxide concentration, atmospheric pressure, and flue gas parameters. All measurement results are calibrated through a standard metrological traceability system to ensure the reliability of the data source. This effectively overcomes the error accumulation problems caused by difficulties in parameter collection and poor applicability of default emission factors in traditional accounting methods, thereby improving the accuracy of carbon emission measurements.

[0054] See Figure 1The present invention discloses a schematic diagram of a carbon emission monitoring device. The carbon emission monitoring device is deployed at the exhaust gas outlet of a cement clinker production facility. The carbon emission monitoring device includes: a carbon dioxide monitor 10, a barometer 20, a flue gas parameter monitoring device 30, and a data processing device 40.

[0055] Among them, the carbon dioxide monitor 10 is used to monitor the concentration of carbon dioxide in flue gas.

[0056] The core principle of the carbon dioxide monitor is non-dispersive infrared absorption, which infers the gas concentration by measuring the degree to which carbon dioxide molecules absorb infrared light of a specific wavelength. In this application, the entire carbon emission monitoring device is deployed at the exhaust gas outlet of the cement clinker production facility. Based on this, the carbon emission monitoring device can monitor the carbon dioxide concentration in the flue gas in real time.

[0057] Barometer 20 is used to monitor atmospheric pressure.

[0058] A barometer is an instrument used to measure atmospheric pressure. Its core principle is based on the correlation between gas pressure and physical effects. Depending on the technology used, barometers are mainly divided into mechanical barometers (such as mercury barometers and anodic barometers) and electronic barometers (such as piezoresistive and piezoelectric sensors).

[0059] The inventors discovered that atmospheric pressure is an indispensable correction parameter in carbon emission calculations. On one hand, the flue gas flow rate under actual operating conditions needs to be corrected for atmospheric pressure to improve the accuracy of the final carbon emission calculation; on the other hand, atmospheric pressure also indirectly affects the calculated carbon emission results by influencing flue gas density. Therefore, atmospheric pressure must be collected in real time in carbon emission monitoring devices to ensure the accuracy of carbon emission measurements.

[0060] Flue gas parameter monitoring device 30 is used to monitor flue gas parameters.

[0061] The flue gas parameter monitoring device 30 in this application adopts integrated multi-parameter sensing technology. Through modular design, multiple independent monitoring modules are packaged into the same device to realize the synchronous real-time acquisition of key parameters such as flue gas flow rate, flue gas temperature, and flue gas static pressure.

[0062] The data processing device 40 is connected to the carbon dioxide monitor 10, the barometer 20 and the flue gas parameter monitoring device 30, respectively, to obtain the carbon dioxide concentration, atmospheric pressure and flue gas parameters in the flue gas, and to comprehensively process the carbon dioxide concentration, atmospheric pressure and flue gas parameters to obtain the carbon emissions.

[0063] In carbon emission monitoring scenarios, the real-time performance and accuracy of carbon emission calculations can be improved by comprehensively processing carbon dioxide concentration, atmospheric pressure, and flue gas parameters collected at the exhaust outlets of cement clinker production facilities.

[0064] In summary, this invention discloses a carbon emission monitoring device deployed at the exhaust outlet of a cement clinker production facility. The device includes a carbon dioxide monitor 10, a barometer 20, a flue gas parameter monitoring device 30, and a data processing device 40. The carbon dioxide monitor 10 monitors the carbon dioxide concentration in the flue gas, the barometer 20 monitors atmospheric pressure, the flue gas parameter monitoring device 30 monitors flue gas parameters, and the data processing device 40 comprehensively processes the carbon dioxide concentration, atmospheric pressure, and flue gas parameters to obtain the carbon emission amount. This invention, by deploying the carbon emission monitoring device at the exhaust outlet of a cement clinker production facility, achieves full-process, real-time, and traceable monitoring of key parameters in the emitted flue gas. The carbon emission monitoring device adopts a multi-sensor collaborative monitoring architecture, simultaneously collecting carbon dioxide concentration, atmospheric pressure, and flue gas parameters. All measurement results are calibrated through a standard metrological traceability system to ensure the reliability of the data source. This effectively overcomes the error accumulation problems caused by difficulties in parameter collection and poor applicability of default emission factors in traditional accounting methods, thereby improving the accuracy of carbon emission measurements.

[0065] Furthermore, in traditional carbon emission accounting methods, process data such as fuel consumption and product output are primarily provided by enterprises, and emission factors mainly use default values ​​(i.e., empirical values) from accounting guidelines rather than actual measured values. This can lead to discrepancies in the carbon emission accounting results reported by enterprises, requiring environmental management departments to commission third-party verification agencies to conduct a second review of their accounting reports to verify data accuracy. However, this process involves multiple stages, including on-site investigation, parameter tracing, and cross-validation, resulting in a long final confirmation cycle for carbon emission data for individual enterprises and significantly reducing the efficiency of carbon emission supervision.

[0066] The carbon emission monitoring device disclosed in this invention enables real-time, full-process monitoring of carbon emissions from the exhaust outlets of cement clinker production facilities. Environmental protection authorities can refer to the regulatory model of the Continuous Emission Monitoring System (CEMS) to conduct routine inspections, data comparisons, and anomaly warnings of the carbon emission monitoring device, and complete compliance verification of the monitoring results through an automated review platform. This model achieves two-way collaboration between enterprise self-certification and government supervision, significantly reducing the cost of carbon emission accounting in the cement industry, decreasing the frequency of manual verification by regulatory authorities, and simultaneously ensuring both data accuracy and regulatory timeliness.

[0067] In one embodiment, see Figure 2 A schematic diagram of another carbon emission monitoring device disclosed in this embodiment of the invention is shown. Figure 1Based on the embodiment shown, the flue gas parameter monitoring device 30 may include: a flow meter 31, a temperature sensor 32, and a pitot tube 33.

[0068] Flow meter 31 is used to monitor flue gas flow.

[0069] Flue gas flow rate refers to the volume or mass of flue gas passing through a flue or exhaust outlet per unit time, usually measured in standard cubic meters per hour (m³ / h). Flue gas flow rate is a core parameter for measuring the total amount of industrial waste gas emissions, directly affecting the emission of pollutants (such as CO2, SO2, NO). X The accuracy of accounting.

[0070] Flow meters calculate flue gas flow rate by measuring the physical properties (such as velocity, pressure, and temperature) or chemical properties (such as thermal conduction and ultrasonic attenuation) of flue gas and combining them with fluid dynamics formulas.

[0071] Temperature sensor 32 is used to monitor smoke temperature.

[0072] Flue gas temperature refers to the temperature of flue gas generated during industrial combustion or technological processes at the emission point or within the pipeline, usually expressed in degrees Celsius (°C). Flue gas temperature is a key parameter reflecting combustion efficiency, equipment operating status, and pollutant formation characteristics, directly affecting pollutant emissions.

[0073] Temperature sensors detect the heat exchange between flue gas and sensor elements, converting the temperature signal into an electrical or digital signal to monitor the flue gas temperature.

[0074] In practical applications, the selection of temperature sensor 32 needs to meet the requirements of temperature measurement range (e.g., 150℃~300℃), accuracy requirements (e.g., ±2℃), and environmental conditions (e.g., adaptable to environments with high dust content and slight corrosiveness).

[0075] Pitot tube 33 is used to monitor flue gas static pressure.

[0076] Flue gas static pressure is the pressure exerted vertically on a unit area of ​​the pipe wall when gas flows through it. Static pressure is the basis for calculating total and dynamic pressure of flue gas, and directly affects the calculation of flue gas velocity, flow rate, and pollutant emissions. For example, in monitoring flue gas at the tail of cement kilns, static pressure data is used to correct flow meter readings and ensure the accuracy of denitrification catalyst efficiency assessments.

[0077] Pitot tubes are tubular velocity measuring devices based on fluid mechanics principles. They calculate the velocity by simultaneously measuring the total pressure and static pressure of the fluid and using the difference between the two (i.e., dynamic pressure), while also enabling direct monitoring and data output of flue gas static pressure.

[0078] In practical applications, the carbon dioxide monitor 10 can measure carbon dioxide concentration using the cold-drying method, or it can measure carbon dioxide concentration using the hot-wet method or the dilution method. This depends on whether the carbon dioxide monitor 10 has a condensation dehumidification module.

[0079] If the carbon dioxide monitor 10 does not have a condensation and dehumidification module, the flue gas monitored by the carbon dioxide monitor 10 has a certain moisture content. That is, the carbon dioxide monitor 10 uses the hot-wet method or the dilution method to monitor the carbon dioxide concentration in the flue gas. In this case, the data processing device 40 uses the method shown in formula (1) to obtain the carbon emission:

[0080] (1);

[0081] In the formula, This represents the carbon emissions from stationary pollution source outlets, in kg / h. This indicates the wet-basis volume ratio of carbon dioxide in the flue gas, i.e., the way the carbon dioxide concentration is expressed on a wet basis. The flue gas flow rate is expressed in meters (m³). 3 / h, The smoke temperature is indicated in °C. The atmospheric pressure is expressed in Pa. The static pressure of the flue gas is expressed in Pa.

[0082] If the carbon dioxide monitor 10 has a condensation dehumidification module, the flue gas monitored by the carbon dioxide monitor 10 has been dried and has a low moisture content. That is, the carbon dioxide monitor 10 uses the cold drying method to monitor the carbon dioxide concentration in the flue gas. In this case, if... Figure 2 As shown, the flue gas parameter monitoring device 30 also includes:

[0083] The hygrometer 34 is used to monitor the moisture content of flue gas.

[0084] Flue gas moisture content refers to the amount of water vapor contained in a unit volume or unit mass of flue gas. Flue gas moisture content is a key parameter describing the water vapor content in flue gas; it reflects the proportion of moisture in the flue gas and has a significant impact on industrial emission monitoring, combustion efficiency assessment, and pollutant control.

[0085] Correspondingly, the data processing device 40 uses the method shown in formula (2) to obtain the carbon emissions:

[0086] (2);

[0087] In the formula, This represents the carbon emissions from stationary pollution source outlets, in kg / h. This indicates the dry-basis volume ratio of carbon dioxide in flue gas, i.e., the way the carbon dioxide concentration is expressed on a dry basis. The flue gas flow rate is expressed in meters (m³). 3 / h, The smoke temperature is indicated in °C. The atmospheric pressure is expressed in Pa. This indicates the static pressure of the flue gas, in Pa. This indicates the moisture content of the flue gas.

[0088] It should be noted that the wet volume ratio of carbon dioxide in flue gas shown in formula (1) and the dry volume ratio of carbon dioxide in flue gas shown in formula (2) are both ways of expressing carbon dioxide concentration under different benchmarks. They are converted by moisture content and are directly related to carbon dioxide concentration, but they are used in different scenarios.

[0089] Corresponding to the above-described device embodiments, the present invention also discloses a method for monitoring carbon emissions.

[0090] See Figure 3 The present invention discloses a flowchart of a carbon emission monitoring method, which is applied to... Figure 1 and Figure 2 The data processing device 40 in the illustrated embodiment includes a carbon emission monitoring method comprising the following steps:

[0091] Step S101: Obtain the carbon dioxide concentration, atmospheric pressure, and flue gas parameters in the flue gas.

[0092] Flue gas parameters can include flue gas flow rate, flue gas temperature, and flue gas static pressure.

[0093] Step S102: The carbon dioxide concentration, atmospheric pressure, and flue gas parameters are processed comprehensively to obtain the carbon emissions.

[0094] In carbon emission monitoring scenarios, the real-time performance and accuracy of carbon emission calculations can be improved by comprehensively processing carbon dioxide concentration, atmospheric pressure, and flue gas parameters collected at the exhaust outlets of cement clinker production facilities.

[0095] In summary, this invention discloses a method for monitoring carbon emissions, which acquires carbon dioxide concentration, atmospheric pressure, and flue gas parameters, and then comprehensively processes these parameters to obtain the carbon emissions. This effectively overcomes the error accumulation problems caused by difficulties in parameter collection and poor applicability of default emission factors in traditional calculation methods, thereby improving the accuracy of carbon emissions.

[0096] In one embodiment, when the carbon dioxide concentration is obtained using a hot-wet method or a dilution method, step S102 may specifically include:

[0097] Carbon emissions can be obtained using the following formula:

[0098] (1);

[0099] In the formula, This represents the carbon emissions from stationary pollution source outlets, in kg / h. This indicates the wet-basis volume ratio of carbon dioxide in the flue gas, i.e., the way the carbon dioxide concentration is expressed on a wet basis. This indicates the flue gas flow rate, in meters (m³). 3 / h, Smoke temperature, unit: °C The atmospheric pressure is expressed in Pa. This represents the static pressure of the flue gas, in Pa.

[0100] The flue gas parameters include: flue gas flow rate, flue gas temperature, and flue gas static pressure.

Indicates the moisture content of the flue gas;

[0105] The flue gas parameters include: flue gas flow rate, flue gas temperature, flue gas static pressure, and flue gas moisture content.

[0106] In one embodiment, see Figure 4 The flowchart of another carbon emission monitoring method disclosed in this embodiment of the invention is as follows: Figure 3 Based on the illustrated embodiment, after step S102, the following may also be included:

[0107] Step S103: Within a preset time period, carbon emissions are calculated one by one according to the continuous monitoring cycle.

[0108] The preset time period can be flexibly set according to actual monitoring needs, with common periods including monthly, quarterly, or annual periods.

[0109] The monitoring cycle can also be flexibly set according to actual monitoring needs, such as 1 hour.

[0110] Step S104: Add up the carbon emissions from each monitoring period to obtain the total carbon emissions within the preset time period.

[0111] By deploying the carbon emission monitoring device disclosed in this invention at the exhaust outlet of a cement clinker production facility, continuous and automatic monitoring of carbon emissions can be achieved. Real-time data can be generated by default with a 1-hour calculation period. When it is necessary to calculate the total monthly, quarterly, or annual emissions, the results can be obtained simply by summing the emissions for each hour within the calculation period.

[0112] Corresponding to the above method embodiments, the present invention also discloses a carbon emission monitoring system.

[0113] See Figure 5 The present invention discloses a schematic diagram of a carbon emission monitoring system, which is applied to... Figure 1 and Figure 2 The data processing device 40 in the illustrated embodiment, the carbon emission monitoring system includes:

[0114] The acquisition unit 201 is used to acquire the carbon dioxide concentration, atmospheric pressure, and flue gas parameters in the flue gas.

[0115] Flue gas parameters can include flue gas flow rate, flue gas temperature, and flue gas static pressure.

[0116] The carbon emission determination unit 202 is used to comprehensively process the carbon dioxide concentration, the atmospheric pressure and the flue gas parameters to obtain the carbon emission amount.

[0117] In carbon emission monitoring scenarios, the real-time performance and accuracy of carbon emission calculations can be improved by comprehensively processing carbon dioxide concentration, atmospheric pressure, and flue gas parameters collected at the exhaust outlets of cement clinker production facilities.

[0118] In summary, this invention discloses a carbon emission monitoring device that acquires carbon dioxide concentration, atmospheric pressure, and flue gas parameters. The carbon emission amount is obtained by comprehensively processing these parameters. Based on multimodal data fusion technology, the device deeply mines the correlation between carbon dioxide concentration, atmospheric pressure, and flue gas parameters, effectively overcoming the error accumulation problems caused by high parameter redundancy and poor applicability of default emission factors in traditional calculation methods, thereby improving the accuracy of carbon emission measurements.
