[0034] Furthermore, a sliding groove is provided at the corresponding position of the fixed rectangular cover 321 and the trapezoidal block 325, and the trapezoidal block 325 is slidably connected inside the fixed rectangular cover 321.

Embodiment
[0037] Please refer to Figures 7-8, and in combination with Embodiment 1, it is further obtained that the catalyst mechanism 2 includes a foam buffer partition 21. The foam buffer partition 21 is arranged on the top of the bottom plate 1. A second catalytic module 28 is arranged inside the foam buffer partition 21. An installation box 22 is arranged inside the foam buffer partition 21. An installation box 23 is arranged inside the installation box 22.

[0038] During the actual operation process, when this device is used, first, insert the side plate 314 into the inside of the baffle 311. The spring 312 inside the baffle 311 pushes the limit bead 313 into the inside of the side plate 314, thereby fixing the side plate 314. Subsequently, place the baffle 311 and the side plate 314 on the top of the bottom plate 1. Then place the foam buffer partition 21 inside the baffle 311 and the side plate 314. Then place the first catalytic module 27, the second catalytic module 28, the installation box 22, and the installation box 23 in sequence. Then place the fixed rectangular cover 321 on the top of the baffle 311 and the side plate 314. Then rotate the rotating rod 322 to drive the screw 324 outside the circular baffle 323 to rotate, so that the screw 324 drives the trapezoidal block 325 to slide inside the fixed rectangular cover 321, and the trapezoidal block 325 drives the limit block 326 to slide inside the fixed rectangular cover 321 and enter the inside of the baffle 311, thereby completing the assembly of the device. By removing the wire mesh, the accumulation of particulate matter is reduced, ensuring the normal operation of the soot blowing system. By setting the foam buffer partition 21, a buffer layer is formed outside the first catalytic module 27 and the second catalytic module 28, which is used to absorb external impacts and vibrations, and prevent mechanical damage to the catalyst during transportation and installation.
