Description

Technical Field

[0001] The present invention relates to the technical field of flue gas monitoring, and particularly to a flue gas temperature monitoring device applied to high-temperature corrosion monitoring. Background Technique

[0002] In industrial processes involving combustion, chemical engineering, and metallurgy, accurately monitoring the temperature of the flue gas generated by production equipment is crucial for evaluating the corrosion resistance of the equipment and optimizing the process conditions. Therefore, flue gas temperature monitoring is not only a key measure to ensure industrial production safety and the normal operation of equipment, but also an important means to optimize the combustion process, improve process efficiency, and meet regulatory requirements. When monitoring the temperature of the flue gas generated by production equipment, a flue gas temperature monitoring device is correspondingly required. When the current flue gas temperature monitoring device is installed and used, generally, the temperature measurement probe is installed on the flue gas pipeline. At this time, the monitoring end of the temperature measurement probe will be inserted into the flue gas pipeline. When the monitoring end of the temperature measurement probe comes into contact with the flue gas in the flue gas pipeline, temperature measurement is achieved. However, because the flue gas contains substances such as soot particles, long-term use will cause soot to adhere to the surface of the temperature measurement probe to form an insulation layer, resulting in an increase in temperature measurement error during subsequent flue gas temperature monitoring, thereby reducing the accuracy of flue gas temperature monitoring. Therefore, we propose a flue gas temperature monitoring device applied to high-temperature corrosion monitoring to solve the above problems. Summary of the Invention

A driving mechanism 9 for driving the annular shell 7 to rotate is arranged on the front bracket 2. One side wall of the back bracket 2 is rotatably connected to a T-shaped block 10 through a bearing. A jack 31 adapted to the support rod 3 is arranged at one end of the T-shaped block 10. One end of the support rod 3 is inserted into the inside of the jack 31.

When the transmission gear 17 rotates back and forth, it can drive the swing rod 11 to swing left and right in cooperation with the T-shaped block 10. Finally, the swing rod 11 will drive the cleaning brush 12 to swing back and forth to clean the arc-shaped filter screen 8 above the annular shell 7. And at the same time of cleaning, the fan 24 can be started. At this time, under the action of the fan 24, the dust removed by cleaning can be collected into the interior of the collection box 19 through the collection pipe 20 and the collection cover 21. Under the action of the filter mesh plate 22, the dust can be retained in the interior of the collection box 19.

One end of the driven ring 903 slidably penetrates through the smoke pipe 1 and extends into its interior and is fixedly connected to the annular shell 7. During use, starting the motor can drive the driving shaft 901 to rotate. After the driving shaft 901 rotates, it can drive the driven ring 903 to rotate in cooperation with the driving gear 902 and the driven gear 904. Finally, when the driven ring 903 rotates, the annular shell 7 can be driven to rotate.
