[0002] Against the backdrop of sustained and steady growth in the domestic economy, the construction and infrastructure sector is booming at an unprecedented pace. From the continuous redefinition of urban skylines to the extensive highway network and public facilities throughout urban and rural areas, every project relies on high-quality cement clinker as its foundation. However, with the increasingly stringent national environmental protection policies and the introduction of energy conservation and emission reduction targets, as well as the continuous improvement of market requirements for the performance of building materials, traditional cement clinker production processes are no longer able to meet current and future needs.

[0031] Example 2

[0032] The rotary kiln carbon dioxide content control device provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3As shown, the device includes a fixed ring 17, which is fixedly connected to the left side surface of the flue gas treatment box 2. A carbon dioxide detection component 11 is movably fitted inside the fixed ring 17. A support ring 18 is fitted onto the outer surface of the fixed ring 17. A torsion spring 19 is fixedly connected to the left side surface of the support ring 18. A rotating ring 20 is fixedly connected to the left end of the torsion spring 19.

[0033] The operation process of the rotary kiln carbon dioxide content control device provided by this utility model is as follows:

[0034] First, the carbon dioxide content in the flue gas is detected by the carbon dioxide detection component 11. After processing by the controller, the opening and closing of the solenoid valve 12 and the power of the blower 7 are adjusted. The blower 7 blows outside air into the interior of the main body 1 through the first transmission pipe 8. At the same time, coal dust mixes with the air through the second transmission pipe 9 and is carried into the interior of the main body 1 by the air. When the carbon dioxide content inside the detector is abnormal, the blower 10 can deliver additional air to the interior of the transfer ring 16 through the third transmission pipe 13, and then to the interior of the mounting ring 14 through the transfer ring 16. Finally, it is transmitted to the interior of the main body 1 through the air inlet pipe 15 to adjust the internal carbon dioxide content. At the same time, when the probe 21 is abnormal due to the presence of a large amount of dust, water vapor and corrosive components in the flue gas, Normally, the vertical rod 26 can be rotated by rotating the ring 20. When the vertical rod 26 rotates, it will simultaneously drive the locking plate 27 to move. When the vertical rod 26 rotates to be close to the inner wall of the other side of the guide groove 25, the locking plate 27 will be aligned with the arc groove 23. At this time, the carbon dioxide detection component 11 and the probe 21 can be directly pulled out. When the ring 20 rotates, it will simultaneously compress the torsion spring 19. After releasing, the ring 20 will be reset by the elastic force of the torsion spring 19, which will then reset the vertical rod 26 and the locking plate 27. After the locking plate 27 is reset, it will be misaligned with the protrusion 28. During installation, simply operate the ring 20 in a similar manner to the above steps to align the locking plate 27 with the protrusion 28 and insert the carbon dioxide detection component 11.
