[0021] The present invention will now be further described with reference to the accompanying drawings. Example
[0022] like Figure 1 and Figure 2As shown, an easily detachable pipe sound absorption and insulation device includes a first sound absorption and insulation part 10 and a second sound absorption and insulation part 20 that cover the outside of the pipe 30 and extend along the laying direction of the pipe 30.
[0023] The second sound-absorbing and insulating part 20 is U-shaped, and the first sound-absorbing and insulating part 10 is fitted onto the outer side of the upper end of the second sound-absorbing and insulating part 20. The first sound-absorbing and insulating part 10 is inverted U-shaped. The first sound-absorbing and insulating part 10 and the second sound-absorbing and insulating part 20 can also be fixed by 304 stainless steel square clamps, which are clamped onto the outer side of the first sound-absorbing and insulating part 10 and the second sound-absorbing and insulating part 20 to facilitate installation and disassembly.
[0024] The first sound-absorbing and sound-insulating part 10 has a first sound-absorbing cotton 13 that contacts the outer wall of the pipe. A first sound-insulating felt 12 is provided on the outside of the first sound-absorbing cotton 13, and a first panel 11 is provided on the outside of the first sound-insulating felt 12. The first panel 11 and the first sound-insulating felt 12, as well as the first sound-insulating felt 12 and the first sound-absorbing cotton 13, are all bonded together by adhesive.
[0025] The second sound-absorbing and insulating part 20 has a second sound-absorbing cotton 23 that contacts the outer wall of the pipe. A second sound-insulating felt 22 is provided on the outside of the second sound-absorbing cotton 23, and a second panel 21 is provided on the outside of the second sound-insulating felt 22.
