Description

Technical Field

[0001] This utility model relates to the field of boiler fly ash detection technology, specifically a device for detecting the carbon content of boiler fly ash in intelligent combustion systems. Background Technology

[0002] Boiler fly ash refers to the fine particles produced during the incomplete combustion of combustibles in fuel at high temperatures during the operation of power plants and industrial boilers. These particles are discharged with the flue gas; some are captured by the dust collector, while others escape the system. The carbon content of fly ash is an important operational and economic indicator for coal-fired power boilers. Based on the detected carbon content, the air-to-coal ratio can be adjusted in a timely manner to improve the combustion efficiency of the coal-fired power boiler, thereby reducing coal consumption and improving the economic efficiency of boiler operation. Detecting the carbon content of fly ash requires collecting the fly ash, measuring the amount of mass loss after complete combustion, and then calculating the carbon content in the fly ash.

[0003] Chinese Patent Publication No. CN214374764U, authorized on October 8, 2021, discloses a device for detecting the carbon content of fly ash in coal-fired power plant boilers. The device includes a boiler, with an ash discharge pipe fixedly connected to one side of the boiler body. The ash discharge pipe has an air inlet and an air outlet at its bottom end. An air inlet pipe and an air outlet pipe are detachably connected to the bottom end of the ash discharge pipe. The air inlet pipe communicates with the air inlet, and the air outlet pipe communicates with the air outlet. The ends of the air inlet pipe and the air outlet pipe furthest from the ash discharge pipe are fixedly connected to an ash hopper. The device can monitor the carbon content of boiler fly ash in real time. The detachable connection between the air inlet pipe, the air outlet pipe, and the ash discharge pipe allows the connection to be disconnected after fly ash collection, facilitating cleaning of the air inlet pipe and the ash hopper, preventing inaccurate carbon content detection. A baffle plate allows more fly ash to enter the air inlet pipe, and a baffle prevents exhaust gas from the ash discharge pipe from entering the air outlet.

[0004] Existing testing devices are inconvenient to disassemble and assemble quickly. During the testing process, fly ash comes into contact with the testing probe, and the fly ash easily adheres to the testing probe, making it inconvenient to clean the testing probe. After multiple tests, the adhered fly ash will affect the accuracy of carbon content detection, and the measurement stability and accuracy are not ideal, making it difficult to meet users' requirements for measurement accuracy and stability. Utility Model Content

[0005] The purpose of this utility model is to provide a boiler fly ash carbon content detection device for intelligent combustion systems, in order to solve the problems mentioned in the background art, such as the inconvenience of quick disassembly and assembly of existing detection devices, the fly ash contacting the detection probe during the detection process, the fly ash easily adhering to the detection probe, the inconvenience of cleaning the detection probe, and the impact of adhering fly ash on the carbon content detection accuracy after multiple tests, resulting in unsatisfactory measurement stability and accuracy, and making it difficult to meet users' requirements for measurement accuracy and stability.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model device is equipped with an electric actuator, a connecting pipe, an exhaust fan, a baffle plate, and a carbon content detection component. The electric actuator drives the carbon content detection component to rise and fall in the detection cylinder.

Under the action of suction, fly ash in the boiler is extracted and sent into the detection cylinder for detection. Then, the detected fly ash is sent back into the boiler through the connecting pipe.

[0024] In use: Drive the electric actuator 5 to lower the carbon content detection component 10 in the detection cylinder 2. As the carbon content detection component 10 descends, the baffle 9 falls down. The falling baffle 9 opens the detection cylinder 2, allowing fly ash from the boiler to enter the detection cylinder 2. The fly ash comes into contact with the carbon content detection component 10, and the carbon content of the fly ash is detected by the carbon content detection component 10. After the detection is completed, drive the electric actuator 5 to raise the carbon content detection component 10 to reset. As the carbon content detection component 10 rises, the baffle 9 is pushed into the mounting base 3, sealing and closing the detection cylinder 2.

[0025] Please see Figure 1 , Figure 2 and Figure 3 The upper end of the mounting base 3 is provided with a connecting ring 12, and the connecting ring 12 is fixedly connected to the mounting base 3. The inner wall of the lower end of the detection cylinder 2 and the outer wall of the connecting ring 12 are both provided with threaded grooves 13, and the detection cylinder 2 is threadedly connected to the connecting ring 12. A data transceiver LCD display 14 is provided on one side of the boiler body 1, and the data transceiver LCD display 14 is connected to the boiler body 1 by screws. The data transceiver LCD display 14 is electrically connected to the carbon content detection component 10. The detection cylinder 2 is threadedly connected to the connecting ring 12, which facilitates the disassembly and assembly of the detection cylinder 2. The detected fly ash carbon content result is displayed through the data transceiver LCD display 14, and the detection result can also be uploaded to realize remote monitoring.

[0026] Please see Figure 1 and Figure 2A blower 7 is installed on one side of the detection cylinder 2, and the blower 7 is connected to the detection cylinder 2 as a whole. A connecting pipe 6 is installed on one side of the blower 7, and the two ends of the connecting pipe 6 are connected to the boiler body 1 and the blower 7 as a whole, respectively. A solenoid valve 8 is installed at the contact point between the connecting pipe 6 and the boiler body 1, and the solenoid valve 8 is connected to the connecting pipe 6 as a whole. The solenoid valve 8 is located outside the connecting pipe 6. When the baffle 9 falls, the blower 7 is turned on to generate suction, and the solenoid valve 8 is opened. Under the action of suction, the fly ash in the boiler is first extracted and sent to the detection cylinder 2 for detection, and then the detected fly ash is sent back to the boiler through the connecting pipe 6.

[0027] Please see Figure 2 and Figure 3 The detection cylinder 2 is equipped with a vibration ring 4 on its outside, and the vibration ring 4 is connected to the detection cylinder 2 by screws.

As the detection cylinder 2 vibrates, the fly ash adhering to the inner wall of the detection cylinder 2 is shaken off, ensuring the accuracy of subsequent fly ash carbon content detection.

[0028] Working principle: The drive electric actuator 5 drives the carbon content detection component 10 to descend in the detection cylinder 2. As the carbon content detection component 10 descends, the baffle 9 falls down. The falling baffle 9 connects the detection cylinder 2, turns on the exhaust fan 7 and opens the solenoid valve 8. The exhaust fan 7 generates suction to draw fly ash from the boiler and send it into the detection cylinder 2. The fly ash comes into contact with the carbon content detection component 10, and the carbon content of the fly ash is detected by the carbon content detection component 10. The detected fly ash is sent into the boiler through the connecting pipe 6. The detected fly ash carbon content result is displayed on the data transceiver LCD display 14. The data transceiver LCD display 14 uploads the detection result to realize remote monitoring. The vibration ring 4 drives the detection cylinder 2 to vibrate. As the detection cylinder 2 vibrates, the fly ash attached to the inner wall of the detection cylinder 2 is shaken off. After the detection is completed, the drive electric actuator 5 drives the carbon content detection component 10 to rise and reset. As the carbon content detection component 10 rises, the baffle 9 is pushed into the mounting base 3, sealing and closing the detection cylinder 2.
