[0012] Beneficial effects

[0013] The present invention provides an ammonia combustion flame scanning and automatic adjustment device based on servo control technology. Compared with the existing technologies, it has the following beneficial effects:

[0014] (1) Through the advanced image processing algorithm and spectral analysis technology of the flame scanner, the present invention can capture the characteristics of the flame and generate an image. Based on technologies such as image enhancement and edge detection, by filtering light of specific wavelengths, such as infrared and visible light radiation, to identify the state of the flame. Through the detection of the ammonia fuel combustion flame state by this technology, based on the detection and analysis data, it is identified whether the ammonia fuel combustion state is complete combustion. The analysis and identification results are fed back to the control center, and further optimize the ratio of ammonia fuel and combustion-supporting agent until the combustion of ammonia fuel reaches the optimal state. It can realize the autonomous monitoring of the ammonia fuel flame in the ammonia-doped combustion of coal-fired boilers, solve the technical problem of the motion trajectory control of the flame scanner, ensure the safety of personnel and the system through precise regulation, energy conservation and environmental protection, and monitoring. At the same time, the system engineering meets the requirements of laws and regulations, reduces the accident and cost risks, and has important significance for protecting the ecological environment.

[0015] (2) The present invention realizes linear motion by adopting a lead screw-nut screw pair. The lead screw-nut screw pair adopts a spiral thread shape. Through the combination of rotation and linear motion, it can achieve high-precision transmission, meet the requirements of the mechanism for position control. The structure of the lead screw-nut screw pair is simple and runs smoothly. Due to the self-locking function of this structure, the working reliability is high, and it is easy to maintain; for the lead screw-nut screw pair, due to the small friction force, the transmission efficiency is higher.

[0016] (3) In the present invention, the prime mover is driven by a servo DC motor. The rotation speed and position of the servo DC motor can achieve high-precision control. The current and voltage of the motor are automatically adjusted through the servo control system, enabling the motor to rotate to the required position and speed. The servo DC motor can adapt to various load types, including constant loads, variable-speed loads, and sudden loads, etc. Therefore, it is more suitable for the various functions required by the present invention. The control system is a PLC-based servo control system. Through the closed-loop control system, the PLC servo control system can monitor and adjust the operating state in real time, ensuring the stability and reliability of the flame scanner during operation. The PLC servo control system can operate stably in a complex environment, take timely measures when problems occur, and ensure the stable operation of the system. It can achieve multi-axis coordinated control and is suitable for the control and coordination of complex mechanism operating trajectories.

[0017] (3) The motion mechanism of the present invention is realized by a three-dimensional multi-link mechanism, which can achieve three-dimensional motion with a single degree of freedom or multiple degrees of freedom. This mechanism is composed of multiple links and joints, can achieve complex motion trajectories and action postures, can easily realize the mechanical actions of the invention, meet the high-precision motion requirements, and can maintain good dynamic stability; it has good adjustability, can adjust the application parameters to achieve the best spatial position, and can realize the scanning trajectory control of the flame scanner along the horizontal plane and the vertical plane respectively.
