[0050] In one embodiment, the above step S4 further includes steps B1 to B4:

[0051] like Figure 2The figure shows a secondary air system for a four-corner tangential boiler, which consists of a management platform, a control platform, a maintenance platform, and an operation data management platform.

[0052] In B1: Figure 3 As shown, the machinery management has machinery maintenance aging reminder and machinery maintenance. At this time, when the machinery reaches the maintenance aging after being used for a period of time, the machinery maintenance aging reminder can provide maintenance reminders for users, and the number of times the machinery has been maintained can be intuitively displayed on the machinery maintenance times.

[0053] It should be noted that the machinery management is responsible for reminding the machinery maintenance time and recording the number of machinery maintenance times.

[0054] In B2: Figure 4 As shown, further, the control platform is provided with a secondary air manual starting device and a secondary air manual closing device. When the system needs to be used, the system is directly started through the secondary air manual starting device. When the system needs to be closed, the secondary air manual closing device is used to shut down the operation of the system. The secondary air manual starting device is provided with a secondary air speed adjustment device, a secondary air direction adjustment device and a secondary air startup cycle self-check. When the wind speed or wind direction of the secondary air intake needs to be adjusted, it can be adjusted directly through the secondary air speed adjustment device and the secondary air direction adjustment device. In order to ensure the normal operation of the system, a secondary air startup cycle self-check will be performed during the operation of the system.

[0055] The advantage of the control platform is that a secondary air speed adjustment device and a secondary air direction adjustment device are arranged inside the secondary air manual starting device. At this time, when using the system, when it is necessary to adjust according to the combustion state inside the four-corner cut-circle boiler, the secondary air speed adjustment device and the secondary air direction adjustment device can be directly used to adjust the wind speed or wind direction of the secondary air at the time of air inlet. At this time, the secondary air speed adjustment device can be used to increase the wind speed inside the four-corner cut-circle boiler, and the secondary air direction adjustment device can be used to adjust the wind direction of the secondary air. In addition, a secondary air start-up cyclic self-check is arranged inside the secondary air manual starting device. The cyclic self-check during secondary air start-up can ensure the normal operation of the system, which is very convenient to use and improves the combustion efficiency.

[0056] It should be noted that the general process for adjusting the secondary wind speed or wind direction is: adjust the wind speed or wind direction during air intake through the wind speed adjustment device and the wind direction adjustment device, and perform a cyclic self-check.

[0057] In B3: Figure 5As shown, further, the maintenance platform will perform a cyclic self-inspection of the secondary air operation when the system is running. When there is no fault in the cyclic self-inspection, the system will continue to operate. When a circulation component fails, the secondary air automatic shut-off device will automatically shut down the operation of the system, start the manual self-inspection of the secondary air system, and feedback whether there is a fault or not through the manual self-inspection of the secondary air.

[0058] The benefit of the maintenance platform is that when the four-corner cut circle boiler is in use, the cyclic self-check during the secondary air operation will be turned on. At this time, the cyclic self-check during the secondary air operation is used to inspect the four-corner cut circle boiler. When the four-corner cut circle boiler fails during use, the secondary air automatic shutdown device will automatically shut down the operation of the system, and then the system can be repaired. When the maintenance is completed, the manual self-check of the secondary air system can be started, and the manual self-check of the secondary air can be used to feedback whether there is any fault. When there is a fault, the data can be adjusted again until the manual self-check of the secondary air system feedback is that there is no fault. At this time, it can provide a safer use process for the four-corner cut circle boiler, and can improve the guarantee of the operation of the four-corner cut circle boiler, which is very stable when used.

[0059] In B4: Figure 6 As shown, further, the operation data management records the operation time, failure time, maintenance time, wind speed and air intake volume, and counts these parameters to provide specific data reference for the subsequent operation of the secondary air system of the four-corner tangential boiler.

[0060] It should be noted that after the system is started, the operation data management is started simultaneously and the above data is recorded until the work is completed. When the system is shut down for fault repair due to a fault, the operation data management is recorded normally.

[0061] Example 2 is an embodiment of the present invention, which provides a secondary air method and system for a four-corner tangential boiler. In order to verify the beneficial effects of the present invention, scientific demonstration is carried out through economic benefit calculation and simulation experiments.

[0062] First of all, this test focuses on the secondary air method and system for four-corner tangential boilers, aiming to clearly demonstrate its advantages and innovations compared with existing technologies. The test selected 6 four-corner tangential boilers of the same model, specification and similar initial operating status as test objects, named Boiler No. 1, Boiler No. 2, Boiler No. 3, Boiler No. 4, Boiler No. 5 and Boiler No. 6.

[0063] During the test preparation stage, detailed inspection and debugging work was carried out on the relevant systems of each boiler. In terms of personnel management and machinery management, the responsibilities and authority of the main manager, deputy manager and technical staff were clearly defined. The main manager entered the relevant manager and operator information into the system in advance and configured the process of adding and deleting managers. The deputy manager ensured that the communication channels were unobstructed so as to accurately convey various messages. The technical staff prepared the terminal equipment to receive the corresponding messages. The machinery management department carefully calibrated the machinery maintenance time reminder function and set the appropriate machinery maintenance number threshold to ensure that maintenance reminders can be issued in time when potential problems occur in the machinery.

[0064] In terms of the manual secondary air start-up device and related adjustment devices, the accuracy and operability of the wind speed adjustment device and the wind direction adjustment device are fully checked to ensure that they can flexibly and accurately adjust the wind speed and wind direction during air intake within the set range, and at the same time confirm the stability of its connection with the system to avoid problems such as signal transmission failure. For the system startup link, the corresponding initial adjustment parameters of wind speed and wind direction under different working conditions are set in advance to ensure that the wind direction adjustment can be completed quickly according to the established requirements when the system is started, and the wind speed adjustment device and wind direction adjustment device can be accurately driven to work according to actual needs.

[0065] In the cyclic self-check process, debug the self-check program so that it can be automatically started when the system starts, monitor the key parts and operating parameters of the system in real time, and accurately determine whether the system is in normal operation. Once a fault signal is detected, the approximate range of the fault can be accurately located to facilitate subsequent maintenance. In the operation data management module, prepare sufficient storage capacity and set the recording format and frequency of various data to ensure accurate and real-time recording of key data such as operating time, fault time, maintenance time, wind speed, and air intake.

[0066] When the test is officially implemented, the systems of boilers 1 to 6 are started first. The main manager operates the manual start-up device for the secondary air, and makes the initial adjustment to the wind speed and direction at the time of air inlet according to the pre-set parameters through the wind speed adjustment device and the wind direction adjustment device. At the same time, the system automatically starts the cyclic self-inspection process. During the self-inspection process, if a system of a boiler detects a fault, such as a fault prompt that the wind speed of boiler 3 is unstable and exceeds the reasonable range, the system will immediately shut down the operation of the boiler manually. The management platform will quickly arrange the corresponding technical staff to go for maintenance according to the fault prompt. After the maintenance is completed, the self-inspection judgment will be started again. The process is repeated until it is judged that there is no fault and the system resumes normal operation. During the entire operation process, the operation data management module continues to record the corresponding data of each boiler in real time, providing sufficient data support for subsequent analysis. Each boiler goes through such a complete startup, operation, fault handling and data recording process to comprehensively examine the actual performance of the secondary air method and system.

[0067]

[0068] Test results tabular presentation

[0069] Through in-depth analysis of the data in the above table, it can be clearly seen that the secondary air method and system for four-corner tangential boilers have creativity and novelty in many aspects such as wind speed, wind direction control, combustion efficiency improvement, fault prevention and handling, and overall stable operation of the system compared with the existing technology.

[0070] The wind speed of each boiler is basically stable between 18m / s-19.5m / s, and the fluctuation range is relatively small. In the traditional secondary air supply system, due to the lack of an accurate wind speed adjustment device or a real-time feedback mechanism for wind speed adjustment, the wind speed is often difficult to control accurately, and the fluctuation range is large, which may fluctuate between 15m / s-22m / s, which leads to an unstable combustion process and affects the overall combustion efficiency. The present invention, by virtue of the wind speed adjustment device, can accurately adjust the wind speed according to actual needs, so that it is maintained in a relatively stable and reasonable range, ensuring a suitable and stable air supply during the combustion process, and laying a good foundation for subsequent efficient combustion, which reflects its innovative advantages in wind speed control.

[0071] The wind direction angle deviation of each boiler is not large, and is basically maintained in the range of 28°-32°, which shows that the wind direction adjustment device can effectively control the wind direction within the ideal angle range. In contrast, the prior art often lacks an effective wind direction dynamic adjustment mechanism, and the wind direction is prone to large deviations, so that the secondary air entering the boiler cannot accurately match the fuel, causing problems such as uneven and incomplete combustion. The present invention ensures the accuracy and stability of the wind direction through the wind direction adjustment device and the targeted adjustment of the wind direction when the system is started, combined with the real-time monitoring and correction of the wind direction by the cyclic self-check, thereby promoting the full combustion of the fuel. This is undoubtedly a major innovative highlight of the present invention in terms of wind direction control.

[0072] The combustion efficiency data intuitively reflects the advantages of the secondary air method and system. The combustion efficiency of each boiler can generally reach 91% or above, and boiler No. 4 has reached 94%, which is a significant improvement compared to the general combustion efficiency of about 85% under the traditional secondary air system. This is due to the precise adjustment and stable control of wind speed and wind direction, which enables the secondary air and fuel to achieve better mixing and reaction in the boiler, allowing the fuel to be fully burned, reducing energy waste and improving energy utilization, highlighting the important role of this invention in improving combustion effects.

[0073] The indicator of the number of failures can also reflect the advantages of the present invention. Most boilers had fewer failures during the test, such as Boiler No. 2 and Boiler No. 5, which did not even have any failures during the entire test period. Traditional secondary air systems often find it difficult to accurately detect and handle failures in the early stages due to the lack of a complete cyclic self-inspection process and a timely fault handling mechanism, which leads to the accumulation and deterioration of faults, and frequently affects the normal operation of the system. The present invention simultaneously turns on the cyclic self-inspection when the system is started. Once a fault occurs, it can promptly prompt and guide targeted maintenance. It can reasonably arrange personnel maintenance through the management platform, and self-inspect and judge again after maintenance, which effectively reduces the frequency of failures and ensures the stability and reliability of system operation. This reflects its creative design in system maintenance and guarantee.

[0074] In terms of maintenance time data, the overall maintenance time of boilers with faults is within a relatively reasonable range. This is due to the system's ability to accurately locate faults, allowing technical staff to respond quickly and perform accurate repairs, avoiding long maintenance times due to difficulties in troubleshooting under traditional technologies. The average operating time data shows that the system can maintain stable operation for a long time, further verifying the reliability and practicality of the secondary air method and system.

[0075] In summary, through comparative analysis of various data in the table, it can be seen that the invention has shown significant creativity and novelty in many aspects such as wind speed, wind direction control, combustion efficiency improvement, fault prevention and handling, and overall stable operation of the system compared with the existing technology. It has extremely high application value and is expected to bring major improvements and breakthroughs in the field of secondary air supply for four-corner cut-circle boilers, and provide strong support for related industries to improve production efficiency, reduce energy consumption, etc.

[0076] Embodiment 3 is an embodiment of the present invention, which provides a secondary air system for a four-corner tangential boiler, including a management module, a control module, and a maintenance module.

[0077] The management module is used to perform mechanical management on the system.

[0078] The control module is used to start the manual secondary air starting device, adjust the wind speed or wind direction during air intake through the wind speed adjusting device and the wind direction adjusting device, and perform cyclic self-checking.

[0079] The maintenance module is used to: make judgments through the above-mentioned cyclic self-check process. When there is a fault: shut down the system operation, perform maintenance and self-check again, repeat the process until it is determined that there is no fault, and record the operating time, fault time, maintenance time, wind speed and air intake in real time through operation data management.
