Description

Technical Field

[0001] The utility model relates to the technical field of intelligent chemical production, in particular to a boiler burner temperature monitoring device. Background Art

[0002] At present, combustion boilers are widely used in large chemical plants. Boilers are divided into coal-fired, gas-fired, oil-fired, and electric heating boilers according to the gas mode. Most chemical plants use coal-fired methods. The process technology uses anthracite and fuel coal as fuels and mixes them with air feed in the furnace to burn. The combustion generates heat to supply boiler water in the drum to generate steam. The mixing part is at the boiler burner. After ignition, the burner temperature and furnace temperature will be monitored. Coal-fired boilers have high coal heat and high thermal efficiency. Their reliability and stability have withstood the test of time and have played an indelible role in the development of my country's industrial economy.

[0003] During the operation of the boiler, a vital equipment component is the boiler burner. Due to the high flow rate of the air inlet duct and the air volume as the key control point for adjusting the boiler load, if the boiler burner temperature is abnormal or there is leakage, it will cause the boiler to reduce its capacity at the least and serious fire accidents at the worst. The inspection of the device mainly relies on people to observe the fire viewing holes on the furnace wall. If there are abnormal situations, there will also be safety risks. However, it is impossible for the inspection personnel to stay at each fire viewing hole all the time. The observation requirements of the human eye are also high. When the human eye is in the observation state for a long time, blindness will occur. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a boiler burner temperature monitoring device, which transmits the abnormal burner temperature signal to the DCS system in time through thermal imaging monitoring, reminds the operator to deal with it in time, reduces the possibility of safety risks, and ensures the normal operation of the equipment.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A boiler burner temperature monitoring device comprises a coal-fired boiler, wherein a burner fire viewing hole is provided on the outer wall of the coal-fired boiler, the burner fire viewing hole faces the boiler burner in the coal-fired boiler, a 5G thermal imaging camera is provided outside the coal-fired boiler and is aimed at the burner fire viewing hole, and the 5G thermal imaging camera is connected to an AI analysis server.

[0007] The above-mentioned AI analysis server is connected to the DCS host computer.

[0008] The above-mentioned DCS host computer is connected to the DCS system.

[0009] The above-mentioned coal-fired boiler is provided with a plurality of burner fire viewing holes along the axial direction, and a 5G thermal imaging camera is aimed at each burner fire viewing hole.

[0010] The boiler burner is connected to fuel and air pipelines, and the fuel and air pipelines extend out of the coal-fired boiler.

[0011] The output end of the above-mentioned DCS system is provided with an alarm device.

[0012] The utility model provides a boiler burner temperature monitoring device, which realizes the whole-area monitoring of the entire boiler fuel combustion operation. Abnormal temperature at any position of the burner and pipeline can be timely alarmed and output, which minimizes the boiler safety risk and avoids the deficiency of manual inspection that cannot be maintained at all times. At the same time, it avoids the misjudgment caused by the difference in human vision and protects the eyes, thus ensuring the normal operation of the device production.
