[0041] The first sound-absorbing member 210 and the second sound-absorbing member 220 are made of sound-absorbing cotton or other sound-absorbing materials, and the shapes of the first sound-absorbing member 210 and the second sound-absorbing member 220 depend on the shapes of the second air guide member 262 and the third air guide member 263. The first sound-absorbing member 210 is arranged in the area surrounded by the second air guide member 262, and the first sound-absorbing member 210 is a solid structure and is attached to the inner surface of the second air guide member 262. The first sound-absorbing member 210 with a solid structure has higher sound-absorbing performance than other structures, especially when the first sound-absorbing member 210 is arranged at the core position of the air guide component 260, it can more effectively absorb and dissipate sound wave energy, reduce the reflection and propagation of sound waves, and thus reduce the noise level. The second sound-absorbing member 220 is clamped in the third air guide member 263.

[0042] With the above design, the fourth air guide member 264, together with the first air guide member 261 and the second air guide member 262, forms two air guide channels arranged left and right, and each air guide channel is divided into two sub-channels arranged in the front and back directions by the third air guide member 263. In this way, the fourth air guide member 264 can be connected with other air guide members to form a solid air guide component 260 with a frame structure in horizontal cross section, so that the overall structural strength of the air guide component 260 is improved, thereby reducing the vibration amplitude of the air guide component 260 during the passage of flue gas, and further reducing the noise generated.

Specifically, the third air guide member 263 is detachably connected between the two first air guide members 261, and the second air guide member 262 is detachably arranged on the third air guide member 263.

[0051] With the detachable design, the assembly process of the air guide part 260 is more flexible and convenient, which helps to reduce the assembly cost and improve the assembly efficiency. When a certain air guide member or sound absorption member in the air guide part 260 fails or needs to be cleaned, it can be easily disassembled and replaced or cleaned, which helps to prolong the service life of the air guide part 260 and reduce the maintenance cost.

[0052] In an embodiment, the air guide part 260 can be made of a material with good sound conduction performance, i.e., the first air guide member 261, the second air guide member 262, the third air guide member 263 and the fourth air guide member 264 are all made of a material with good sound conduction performance, such as metal, alloy or other materials with excellent sound conduction performance.
