[0002] As the core equipment of thermal power plants, boilers are crucial to their safe operation. Abnormal detection and analysis of boiler pipelines is an important part of boiler safe operation. Over the years, a lot of work in this area has been carried out at home and abroad.

[0003] The leakage of the "four pipes" is mainly caused by overheating, overpressure, wear, corrosion and other reasons. Traditional research work mainly revolves around these, and mature practices have been formed in monitoring, operation, maintenance, management and other aspects. In the past, manual methods were mostly used to carry out anti-wear and explosion prevention work for power station boilers. Although the data analysis support platform has been applied in large thermal power plants, there are few of them, and the current functions are not perfect. Data from all aspects are not fully integrated, which affects its application functions. The data analysis support platform of this project is built on the basis of relatively complete underlying data, which ensures the development of subsequent functions.

[0004] However, in the prior art, a corresponding air leakage monitoring system is not provided for the running semi-dry desulfurization system, resulting in the need for manual regular and fixed-point inspections to perform air leakage monitoring in actual use, which is time-consuming and labor-intensive, and it is also easy to fail to find the actual air leakage location in the first place, resulting in increased energy consumption of the semi-dry desulfurization system and prolonged equipment downtime.

The flue air leakage monitoring system of the semi-dry desulfurization system according to claim 5 is characterized by: The equipment information ledger is used to quickly query the design data of each installed equipment and supports the unified filing of equipment-related electronic documents and other files; The equipment operation record is used to record the start and stop time of each equipment, the over-temperature position of the pipe wall, the over-temperature statistics, the over-temperature amplitude, the over-temperature duration and the over-temperature frequency data, and at the same time record the flue where the air leakage occurs, and form an equipment failure warning through data statistical analysis, and intuitively display it in the form of a curve chart; The equipment maintenance record is used to record actual measurements and macro inspections, record the maintenance history of each piece of equipment in detail, record and analyze the pipe wall wear in detail, and issue different levels of early warning for pipe wall wear and air leakage; The equipment management ledger is used to manage anti-wear and explosion-proof maintenance briefings, anti-wear and explosion-proof organizational responsibilities, maintenance system standards, operation system standards, anti-accident measures, reward and punishment system standards and other management anti-wear and explosion-proof related system regulations and standards, and authorizes mobile devices to conduct on-site online data recording and graphical historical query and comparative analysis.

7. The flue air leakage monitoring system of the semi-dry desulfurization system according to claim 1 is characterized by: The equipment registration module includes an equipment purchasing unit and an equipment installation unit, and the output ends of the equipment purchasing unit and the equipment installation unit are both communicatively connected with the input end of the four-tube anti-wear and explosion-proof safety management terminal.

8. The flue air leakage monitoring system of the semi-dry desulfurization system according to claim 7 is characterized in that: The equipment purchasing unit is used to register the equipment purchasing records required for the operation of the semi-dry desulfurization system one by one; The equipment installation unit is used to record the position of each installed equipment in real time and display it in a table.

9. The flue air leakage monitoring system of the semi-dry desulfurization system according to claim 1 is characterized by: The communication alarm module comprises an alarm unit, a communication management unit and an audit feedback unit. The output end of the communication management unit is communicatively connected to the input end of the audit feedback unit. The alarm unit and the communication management unit are bidirectionally communicatively connected.

10. The flue air leakage monitoring system of the semi-dry desulfurization system according to claim 9 is characterized in that: The alarm unit is used to set a threshold value, and when it is detected that the air leakage exceeds the set value, an alarm is automatically issued through an external early warning device; The communication management unit is used to support remote monitoring and data transmission, and upload monitoring data to the cloud platform via the Internet or local area network; The audit feedback unit is used to build a cloud platform and record each air leakage monitoring process on the cloud platform.
