Description
Technical Field
The utility model relates to a pipeline silencer.
Background
The pipe silencer (silencer) is mainly used for effectively silencing the steam emission of boilers, turbines and other thermal equipment in the power generation department. Meanwhile, the method is widely applied to boiler steam emission and other gas silencing emission in industries such as petroleum, chemical engineering, metallurgy, textile and the like. The existing silencer is relatively complex in structure, the structure of an internal pipeline is not stable enough, the internal pipeline of the silencer is easy to displace in the working process, and the use of the silencer is influenced.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a pipeline silencer, which comprises a shell, wherein one end of the shell is provided with an air inlet pipe, the other end of the shell is provided with an end cover, and the end cover is provided with an air outlet pipe; the shell is internally provided with a baffle, a silencing pipeline and a mounting plate; the baffle is arranged on the inner wall of the shell at the side of the air inlet pipe through a fixing piece; the silencing pipeline is arranged between the baffle and the end cover and is fixed on the mounting plate; the mounting plate is provided with a through hole matched with the silencing pipeline and is fixed on the inner wall of the shell; the sound-absorbing cotton is arranged on the air outlet pipe.
Further, the fixing piece is a round pipe.
Further, the silencing pipeline is multiple.
Further, the end cap and the housing are connected by a flange.
The utility model has the advantages of simple and reasonable structure, reflect the air current through the baffle, then amortization pipeline amortization is shunted, through inhaling the cotton output of sound at last, has improved the noise cancelling effect.

Detailed Description
As shown in fig. 1, the pipeline silencer comprises a shell 4, wherein an air inlet pipe 9 is arranged at the bottom end of the shell 4, an end cover 3 is arranged at the top end of the shell, and an air outlet pipe 1 is arranged on the end cover 3. The shell 4 is internally provided with a baffle 7, a silencing pipe 6 and a mounting plate 5. The baffle 7 is provided on the inner wall of the casing 4 on the side of the intake pipe 9 by a fixing member 8. The silencing pipe 6 is arranged between the baffle 7 and the end cover 3, and the silencing pipe 6 is fixed on the mounting plate 5; the mounting plate 5 is provided with a through hole 11 matched with the silencing pipeline 6, and the mounting plate 5 is fixed on the inner wall of the shell 4 through a bolt. The sound-absorbing cotton 2 is arranged on the air outlet pipe 1, so that the noise elimination effect is improved.
The fixing piece 8 is a round pipe, so that gas can pass through the fixing piece conveniently, and noise is reduced.
The silencing duct 6 is plural.
The end cover 3 is connected with the shell 4 through the flange 10, so that the maintenance is convenient.
