Flame monitoring system
The furnace flame monitoring device is a color industrial TV monitoring system that monitors the combustion state of fuel 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 centrally controlled monitor, and can find out the abnormal combustion and special situations in the furnace in time, and deal with them accordingly. The application of this device avoids the occurrence of various safety accidents, and is a reliable guarantee for the safe, economical and stable operation of various industrial furnaces.
System composition and principle
The FTV furnace flame monitoring device is composed of an optical image transmission mechanism, a motion mechanism, a protection mechanism, a control mechanism and a connection display mechanism. Its working principle is to image the combustion flame in the furnace through a high-temperature imaging lens probed into the furnace, and then the optical relay group in the mirror tube transmits the captured flame image to the end of the mirror tube located in the protective cover outside the furnace. On the target surface of the camera, the CCD converts it into an electrical signal and sends it to the monitor in the control room. Therefore, the monitoring personnel can clearly see the real image of the flame burning in the furnace in the control room.
The lenses of the FTV furnace flame monitoring device are all optical lenses developed by our company for the weapons and equipment of the National Defense Science and Technology Commission, especially the protective lenses are made of sapphire material through precise processing technology, which has strong high temperature resistance and corrosion resistance. performance.
So as to ensure the clarity of imaging (up to 4K resolution) and high temperature resistance (up to 2000 ℃). The electronic components installed are imported from foreign brands to ensure the stability and reliability of the device operation. Aiming at 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. The air-cooling protection technology uses the instrument wind to cool the lens and mirror tube of the device, and the air-cooling protection of the camera adopts our company's cyclone separation refrigerator. The cyclone separation refrigerator is to introduce the instrument air into the refrigerator, separate it into hot air and cold air, and the hot air is discharged through the refrigerator. The cold air effectively cools the camera, ensuring long-term, stable and reliable operation of the camera.
The FTV type furnace flame monitoring device has formed a variety of products, multiple specifications and serialized products, with the advantages of self-protection, interlocking control and remote operation. In addition, users can choose product functions with different configurations according to the needs of on-site working conditions, such as electric axial rotation (patent number: ZL201420250419.8), 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 work of various industrial furnaces and kilns, and is mainly suitable for petrochemical, electric power, metallurgy and other fields.
