Furnace flame monitoring device
Release time:
2020-03-23
The furnace flame monitoring device is a color industrial television monitoring system that monitors the combustion status of fuels in various industrial furnaces. The system integrates optics, mechanics and electronics. Through this system, the operator can monitor the real flame image in the furnace in real time from the monitor of the centralized control chamber, and can find the abnormal combustion and special situation in the furnace in time, and deal with it accordingly. The application of this device avoids the occurrence of various safety accidents and is a reliable guarantee for the safe, economic and stable operation of various industrial furnaces.
system composition and principle
FTV type furnace flame monitoring device is composed of optical image transmission mechanism, motion mechanism, protection mechanism, control mechanism and connection display mechanism. Its working principle is to image the combustion flame in the furnace through a high-temperature resistant imaging lens that enters the furnace, and then the optical transfer group in the mirror tube transmits the captured flame image to the camera target surface located in the protective cover outside the furnace at the end of the mirror tube, and the CCD converts the electrical signal to the monitor in the control room. So that the monitoring personnel in the control room can clearly see the real image of the flame burning in the furnace.
Technical advantages
The lenses of FTV furnace flame monitoring device are all optical lenses developed by our company for the weapons and equipment of the Commission of Science, Technology and Industry for National Defense. In particular, the protective lenses are made of white gem material through precise processing technology, which has strong high temperature resistance and corrosion resistance.
This ensures the clarity of imaging (up to 4K resolution) and high temperature resistance (up to 2000 ℃). The electronic components are imported from abroad to ensure the stability and reliability of the device. In view of the long-term high temperature conditions of the device, in order to better ensure the stable operation of the device, our company adopts air cooling protection technology to cool it. Air cooling protection technology is to use instrument wind to cool the lens and mirror tube of the device, in which the air cooling protection of the camera adopts our company's patented product cyclone separation refrigerator (patent number: ZL 201120083324.8). The cyclone separation type refrigerator introduces the instrument air into the refrigerator, separates and forms hot air and cold air, and the hot air is discharged outward through the refrigerator. The cold air effectively cools the camera to ensure the long-term, stable and reliable operation of the camera.
FTV type furnace flame monitoring device has formed many varieties, many specifications, series products, with self-protection, interlocking control and remote operation, etc. In addition, users can choose different product functions according to the requirements of on-site working conditions, such as electric axial rotation (patent number: ZL 201420250419.8), power-off protection, real-time furnace temperature measurement (patent number: ZL201620568116.X), intelligent control and explosion-proof, etc. This device has a wide range of applications in the monitoring of various industrial furnaces, mainly for petrochemical, electric power, metallurgy and other fields.
