In figure：1- babinets, 11- air inlets, 12- air outlets, 2- noise elimination structures, the first damper elements of 21-, 22- first eliminate the noise
Plate, 3- flow dividing structures, the second damper elements of 31-, the second muffler plates of 32-, 33- sound attenuation holes, 4- flanges, 41- mounting holes.
Specific implementation mode
The embodiments of the present invention are described in further detail below in conjunction with attached drawing.
Shown in Fig. 1 to Fig. 3, a kind of smoke discharging pipe silencing apparatus of the utility model embodiment offer, including babinet 1,
Noise elimination structure 2 in babinet 1 and the flow dividing structure 3 in babinet 1, it is preferred that babinet 1 is stainless steel, and babinet 1 includes
Air inlet 11 and air outlet 12, noise elimination structure include the first damper element 21 and the first muffler plate 22 for being layed in 1 inner wall of babinet, the
One muffler plate 22 is set to the first side of the damper element 21 far from 1 inner wall of babinet, and flow dividing structure 3 includes the second damper element 31 and second
Muffler plate 32, it is criss-cross cavity, the second damper element 31 that the second muffler plate 32, which is enclosed one along gas flow direction section,
In cavity, and the first muffler plate 22 and the second muffler plate 32 are equipped with several sound attenuation holes 33, it is preferred that the first damper element 21
It is mineral wool or rock wool with the second damper element 31, the thickness of the first muffler plate 22 and the second muffler plate 32 is 1mm, and band is arranged
There are the first muffler plate 22 and the second muffler plate 32 of sound attenuation hole 33, the first muffler plate 22 and the second muffler plate can be passed through in gas
