TECHNICAL FIELD

[0001] The utility model relates to the technical field of boiler secondary air anti-coking, in particular to a hearth flame TV secondary air anti-coking base plate. BACKGROUND

[0002] In the operation of industrial boilers, the hearth flame TV is a key equipment for ensuring safe and efficient combustion. It is usually composed of a high-temperature-resistant camera installed inside the boiler and an external display device. The high-temperature-resistant camera captures the dynamic image of the flame burning in the hearth through a special optical system and transmits the signal to the external display screen, allowing the operator to monitor the internal combustion of the boiler and detect abnormalities in a timely manner.

[0003] However, in actual operation, the complex and harsh environment inside the hearth poses many challenges to the equipment. As an important factor in adjusting combustion, the high-temperature particles and complex airflow carried by the secondary air can easily cause the hearth flame TV camera to coking. The traditional base plate has obvious deficiencies in protection and cannot effectively resist the erosion of the secondary air on the camera, resulting in frequent coking, which seriously affects the shooting clarity and service life of the camera and further interferes with the accurate judgment of the combustion state of the hearth, increasing the safety risk and maintenance cost of the boiler operation. Therefore, a hearth flame TV secondary air anti-coking base plate is needed to solve the above problems. SUMMARY

[0008] Preferably, the side wall of the air inlet box is provided with a plurality of avoiding holes, the side wall of the fixing plate is fixedly connected with a plurality of positioning bolts, and the surface of the positioning bolt is movably sleeved with the inner wall of the avoiding hole.

[0009] Preferably, the inner wall of the air inlet box is fixedly connected with a connecting head, and the side wall of the connecting head is provided with a plurality of fixing holes.

[0010] Preferably, the inner wall of the air inlet box is fixedly connected with a sealing ring, and the inner wall of the sealing ring is fixedly connected with the surface of the air inlet pipe.

[0011] Preferably, the high-transparency high-temperature-resistant glass is conical, the plurality of air blowing pipes are obliquely arranged, and the plurality of air blowing pipes are matched in size.

[0012] Compared with the prior art, the utility model has the advantages that:

[0013] Through the anti-coking assembly, the high-pressure air pipe is connected to the inner wall of the air inlet box, the inclination angle of the plurality of air blowing pipes is matched with the conical surface of the high-transparency high-temperature-resistant glass, so that when the high-pressure air pipe releases high-pressure gas in the air inlet box, the high pressure in the air inlet box enters the inner wall of the air inlet pipe, and then acts on the surface of the high-transparency high-temperature-resistant glass through the plurality of air blowing pipes arranged on the inner wall of the air inlet pipe, thereby cleaning the surface of the high-transparency high-temperature-resistant glass and forming a reaction force on the secondary air close to the surface of the high-transparency high-temperature-resistant glass, and the probability of coking of the secondary air on the surface of the high-transparency high-temperature-resistant glass is reduced.
