Description

Technical Field

[0001] The present invention relates to the technical field of environmental protection, and particularly to a test verification system for a hot-state carbon dioxide continuous monitoring device. Background Art

[0002] Thermal power generation, as the main power generation method in China, has made important contributions to the production and life of the people. Although the flue gas emission treatment of thermal power generation has developed to a certain extent, carbon dioxide emission is an inevitable problem. In order to achieve sustainable development, it is necessary to effectively monitor the carbon emissions of thermal power plants to realize scientific management and control of emissions. The carbon emissions of thermal power plants are monitored in real time through a flue gas continuous monitoring system, but at the same time, there are also other devices or equipment that use different means to achieve monitoring. Since the flue gas flow field is complex and changeable when the flue gas is discharged, it will cause large deviations and low accuracy in the measurement results of flue gas flow and CO2 concentration. Therefore, new equipment cannot be directly used for the flue gas monitoring of thermal power plants to avoid affecting the carbon emission management of thermal power plants due to equipment problems. For new monitoring devices, it is necessary to judge the reliability of detection and the adaptability of the monitoring device to different types of flue gas. Summary of the Invention

Specific implementation manners

[0028] The following will describe in detail the specific implementation manners of the embodiments of the present invention with reference to the accompanying drawings. It should be understood that the specific implementation manners described herein are only used to illustrate and explain the embodiments of the present invention, and are not used to limit the embodiments of the present invention.

[0029] This embodiment proposes a test verification system for a hot - state carbon dioxide continuous monitoring device, which is used to form a verification system for different hot - state carbon dioxide continuous monitoring devices. By providing flue gas in different states, the adaptability of the hot - state carbon dioxide continuous monitoring device to flue gas in different states is verified. As Figure 1As shown in the figure, the test verification system includes a flue gas treatment system 1, a flue gas bypass assembly, a test verification platform 5, and a flue gas circuit system 6. The coal in the power plant burns in the furnace to heat water into high-temperature steam and generate flue gas. After denitrification and dust removal, the flue gas is transported through pipelines, and then the flue gas is led out from the pipeline by the flue gas treatment system 1 of the verification system and discharged after treatment. Since the main function of the flue gas treatment system 1 of this application is to perform desulfurization treatment and deep dust removal treatment on the flue gas generated by coal combustion, the flue gas treatment system 1 of this application can be the flue gas treatment part of the existing thermal power generation unit. A series of environmental protection treatments are required for the flue gas generated by coal combustion before it is discharged. The flue gas bypass assembly is connected to different positions of the flue gas treatment system 1 of this application and is used to lead out the flue gas at different treatment levels when passing through the flue gas treatment system 1. Among them, the different treatment levels can be the degree of flue gas desulfurization treatment or the degree of dust removal treatment. The flue gas during the treatment process by the flue gas treatment system 1 is guided to the test verification platform 5 through the flue gas bypass assembly, and the flue gas in different treatment processes is pre-detected and detected through the test verification platform 5. By comparing the detection results of the detection and pre-detection, the adaptability of the carbon dioxide continuous monitoring device 25 to be tested to the flue gas in different states is determined. The flue gas pre-detected and detected through the test verification platform 5 is transmitted back to the flue gas treatment system 1 through the flue gas circuit system 6.

[0030] In this embodiment, the flue gas treatment module of the test verification system includes a first induced draft fan 7, a desulfurization absorption tower 8, an electrostatic precipitator 9, and a chimney 10. The outlet of the first induced draft fan 7 is connected to the inlet of the desulfurization absorption tower 8 through a first pipeline 29, the outlet of the desulfurization absorption tower 8 is connected to the inlet of the electrostatic precipitator 9 through a second pipeline 30, and the flue gas outlet of the electrostatic precipitator 9 is connected to the chimney 10 through a third pipeline 31 to discharge the dust-removed flue gas. The desulfurization absorption tower 8 should be a wet desulfurization absorption tower 8, and the electrostatic precipitator 9 should be a wet electrostatic precipitator 9. The first induced draft fan 7, the desulfurization absorption tower 8, the electrostatic precipitator 9, and the chimney 10 are sequentially connected through the first pipeline 29, the second pipeline 30, and the third pipeline 31 respectively. The flue gas generated by the coal in the thermal power plant is denitrified and dust-removed, and then is drawn by the first induced draft fan 7 to the desulfurization absorption tower 8, and then the flue gas is deeply treated by the electrostatic precipitator 9, and finally discharged through the chimney 10. The flue gas treatment module can be a part of the flue gas treatment in the power plant, making the flue gas treatment equipment in the power plant the flue gas treatment system 1 of this application. It can also be to lead out a part of the flue gas through the first induced draft fan 7 of a separate flue gas treatment system 1, and make the other flue gas pass through the equipment in the power plant for flue gas treatment. When the flue gas treatment equipment in the power plant is used as the flue gas treatment system 1, only the flue gas bypass assembly needs to be connected to the corresponding position to lead out the flue gas at different treatment levels.

[0031] In this embodiment, the flue gas bypass assembly includes three branches: the first flue gas bypass system 2, the second flue gas bypass system 3, and the third flue gas bypass system 4. The first flue gas bypass system 2 is connected to the third pipeline 31 of the flue gas treatment system 1 and is used to draw out the first flue gas after desulfurization treatment and dust removal treatment. The second flue gas bypass system 3 is connected to the second pipeline 30 and is used to draw out the second flue gas after desulfurization treatment but without dust removal treatment. The third flue gas bypass system 4 is connected to the first pipeline 29 to draw out the flue gas at the outlet of the first induced draft fan 7. At the same time, since flue gas treatment may also include other environmental protection treatment methods, other bypass systems can also be set up to draw out the flue gas after being treated by other environmental protection treatment methods. The first flue gas bypass system 2, the second flue gas bypass system 3, and the third flue gas bypass system 4 are respectively and independently connected to the test verification platform 5 to avoid detection errors of the test verification platform 5 caused by the mixing of flue gases in different bypass systems.

[0032] In this embodiment, as Figure 2 shown, the first flue gas bypass system 2 includes a first flue gas detection module 11 and a first valve 12 capable of controlling the flue gas flow rate of the first flue gas bypass system 2. The first flue gas in the first flue gas bypass system 2 is transported through the first conveying pipeline, and the first flue gas detection module 11 and the first valve 12 are installed at corresponding positions on the first conveying pipeline. The first conveying pipeline of the first flue gas bypass system 2 is connected to the flue gas outlet position of the electrostatic precipitator 9, and the flue gas discharged from here is the first flue gas after desulfurization treatment and dust removal treatment. The flow rate of the first flue gas introduced into the first flue gas bypass system 2 is controlled by the first valve 12. When a large amount of first flue gas needs to be detected, only the opening degree of the first valve 12 needs to be increased. The first flue gas detection module 11 detects various parameter data of the first flue gas and serves as one of the comparison data for subsequent tests. Since the flue gas in the first flue gas bypass system 2 is the flue gas after desulfurization and dust removal, the first flue gas in the first flue gas bypass system 2 can also be represented as the simulated hot flue gas of the unit equipped with the wet electrostatic precipitator 9 under different load conditions.

[0033] In this embodiment, the second flue gas bypass system 3 includes a second flue gas detection module 13, a second valve 14, and a flue gas regulation module. The second flue gas of the second flue gas bypass system 3 is transported through a second conveying pipeline, and the second flue gas detection module 13, the second valve 14, and the flue gas regulation module are installed at corresponding positions on the second conveying pipeline. The second valve 14, the second flue gas detection module 13, and the flue gas regulation module are connected in series through the second conveying pipeline in sequence. Since the second flue gas bypass system 3 is connected to the outlet position of the desulfurization absorption tower 8, the second flue gas in the second flue gas bypass system 3 is the flue gas after only desulfurization treatment. The second flue gas adjusts the state of the second flue gas through the flue gas regulation module in the flue gas bypass system to provide various different types of flue gas. The function of the second valve 14 is the same as that of the first valve 12, mainly controlling the flow rate of the second flue gas in the second flue gas bypass system 3. The second flue gas detection module 13 detects various parameter data of the second flue gas when it just exits from the flue gas treatment system 1, which is used as one of the comparison data for subsequent tests. Through the above solution, the second flue gas bypass system 3 can provide the test verification platform 5 with simulated hot flue gas of a unit equipped with wet desulfurization and without a wet electrostatic precipitator 9 under different load conditions.

[0034] In this embodiment, the flue gas regulation module includes a first cooling heat exchanger 15 and a heating heat exchanger 17. The first cooling heat exchanger 15 cools the second flue gas in the second flue gas bypass system 3, causing the water in the second flue gas to condense and changing the humidity of the flue gas. The heating heat exchanger 17 heats the second flue gas to a specified flue gas temperature. The above second flue gas regulation method requires the first cooling heat exchanger 15 and the heating heat exchanger 17 to be connected in series in the second flue gas bypass system 3 in sequence. A third flue gas detection module 16 can be set at the outlet position of the first cooling heat exchanger 15 to detect various parameters of the second flue gas after dehumidification, which is used as one of the comparison data for subsequent tests. A fourth flue gas detection module 18 is set at the outlet position of the heating heat exchanger 17 to detect various flue gas data of the second flue gas after dehumidification and heating, which is used as one of the comparison data for subsequent tests.

[0035] In this embodiment, the third flue gas bypass system 4 includes a third valve 20 and a second cooling heat exchanger 21. The third flue gas in the third flue gas bypass system 4 is transported through a third conveying pipeline, causing the third flue gas to move within the third conveying pipeline, and the third valve 20 and the second cooling heat exchanger are arranged at corresponding positions on the third pipeline. Since the third flue gas bypass system 4 is connected to the outlet of the first induced draft fan 7, the flue gas in the third flue gas bypass system 4 is the third flue gas directly discharged after denitrification and dust removal. The third valve 20 controls the flow rate of the third flue gas in the third flue gas bypass system 4. The second cooling heat exchanger 21 is used to cool the third flue gas and supply the cooled third flue gas that has not undergone wet desulfurization and wet dust removal to the test verification platform 5. A fifth flue gas detection module 19 can be arranged at the flue gas inlet of the second cooling heat exchanger 21 to detect various parameters of the third flue gas that has not passed through the second cooling heat exchanger 21, serving as one of the comparison data for subsequent tests. A sixth flue gas detection module 22 is arranged at the flue gas outlet position of the second cooling heat exchanger 21 to detect various parameters of the cooled third flue gas, serving as one of the comparison data. The third flue gas bypass system 4 can provide the test verification platform 5 with simulated hot flue gas installed under different load conditions of the dry desulfurization unit.

[0036] In this embodiment, as Figure 3 shown, the test verification platform 5 pre-detects and detects the flue gas in different states led out by the flue gas bypass components. The pre-detection is to pre-detect the parameters of various different types of flue gas reaching the test verification platform 5. The detection is carried out by the carbon dioxide continuous monitoring device 25 to be tested. The detected flue gas parameter data is compared with the above-mentioned comparison data to compare the adaptability of the carbon dioxide continuous monitoring device 25 to be tested when detecting flue gas in different states. The flue gas after passing through the carbon dioxide continuous monitoring device 25 to be tested can be transmitted to the flue gas loop system 6 through the second variable flue 26. The pre-detection is achieved through the test pre-detection module 23. After various types of flue gas reaching the test verification platform 5 pass through the test pre-detection, they can be transmitted to the carbon dioxide continuous monitoring device 25 to be tested through the first variable flue 24. Both the first variable flue 24 and the second variable flue 26 include guiding elbows, expanding flues, and contracting flues. By means of the expanding flues and contracting flues, the flow field distribution of the flue gas can be changed, enabling the carbon dioxide continuous monitoring device 25 to be tested to detect the parameters of flue gas with different flow field distributions and examining the adaptability of the carbon dioxide continuous monitoring device 25 to be tested to a complex flow field environment. The expanding flues and contracting flues can be pipes with continuously changing inner diameters.

[0037] In this embodiment, the second induced draft fan 27 of the flue gas circuit system 6 sucks out the flue gas after passing through the test verification platform 5, and is connected back to the first pipeline 29 of the flue gas treatment system 1 through the fourth pipeline 32, so that the flue gas after test verification is harmlessly treated by the flue gas treatment system 1 again. The flue gas in different pipelines reaches the fourth pipeline 32 through the second induced draft fan 27 for mixing, and then passes through the flue gas treatment system 1. A seventh flue gas detection module 28 can be set at the outlet position of the second induced draft fan 27 to detect the flue gas parameters after passing through the test verification platform 5.

[0038] In this embodiment, the test pre-detection module 23 respectively detects information such as the flue gas flow rate and carbon dioxide concentration of the flue gas flowing to this place through a flue gas flow measurement device and a carbon dioxide concentration analyzer. The equipment used by the test pre-detection module 23 for detection should be equipment with high accuracy and adaptability to ensure that the comparison data can more accurately reflect the difference from the data detected by the carbon dioxide continuous monitoring device 25 to be tested.

[0039] The flue gas detection modules arranged at various places in the test verification system, namely the first flue gas detection module 11, the second flue gas detection module 13, the third flue gas detection module 16, the fourth flue gas detection module 18, the fifth flue gas detection module 19, the sixth flue gas detection module 22 and the seventh flue gas detection module 28, respectively detect parameters such as the temperature, humidity, velocity, dust concentration, SO2 concentration, etc. of the flue gas at the positions where the devices are located. The carbon dioxide continuous monitoring device 25 to be tested can include a variety of detection devices such as an ultrasonic flowmeter, a pitot tube flowmeter, a matrix flowmeter, a multi-point pitot tube flowmeter, a optical scintillation flowmeter, a non-dispersive infrared CO2 concentration analyzer, and a tunable laser CO2 concentration analyzer. Compare the data detected by it with the flue gas data detected at other positions in the test verification system, and analyze the adaptability of the carbon dioxide continuous monitoring device 25 to be tested to different flue gases through the comparison data differences. Of course, other flue gas detection devices can also be adaptability-verified through the solution of this application.

[0040] In this embodiment, the temperature change range of the first cooling heat exchanger 15, the second cooling heat exchanger 21 and the heating heat exchanger 17 is 5°C to 15°C. Since the flue gas flowing in the second flue gas bypass system 3 is wet flue gas, it is easy to cause corrosion to the first cooling heat exchanger 15 and the heating heat exchanger 17. Therefore, the materials of the first cooling heat exchanger 15 and the heating heat exchanger 17 are made of corrosion-resistant glass fiber reinforced polypropylene (FRPP), which can significantly improve the safety, reliability and long-term availability of the system.

[0041] In this embodiment, since the second induced draft fan 27 needs to draw out the flue gas led out by three bypass systems, the maximum flue gas volume of the second induced draft fan 27 should not be less than 40000 m3 / h.

[0042] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various changes and modifications can be made to the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included within the scope of the claims of the present application.
