Abstract
The invention discloses a kind of muffler, including interior conduit and Outer Tube, interior conduit is installed in Outer Tube, it is noise reduction layer between interior conduit and Outer Tube, Outer Tube is made up of the horizontal tube and arc convex pipe being spaced, multiple punchings are offered on interior conduit, punching quantity is less than the quantity of punching at interior conduit corresponding to horizontal tube at interior conduit corresponding to boss, interior conduit left end is air inlet, interior conduit right-hand member is gas outlet, air inlet is connected with waste pipe, and exhaust nozzle is coated with gas outlet.It the advantage is that：The present invention near interior conduit with a distance from from Outer Tube by setting up punching so that noise reduction is uniform；By opening up steam vent on Outer Tube, the gas between Outer Tube and interior conduit can be discharged, it is therefore prevented that exhaust sound is empathized in Outer Tube；Simultaneously by installing jet pipe in interior conduit gas outlet, the oil droplet being subjected in interior conduit, prevent the oil droplet in interior conduit to be dropped on muffler, pollute.
Description
Technical field
The invention belongs to ship equipment technical field, and in particular to a kind of muffler.
Background technology
Ship can produce noise while emission, and noise with tail gas is discharged using blast pipe, therefore is being arranged
Tracheal strips will add a muffler, to reduce the generation of noise.Muffler is usually that the inner cylinder with punching is set in outer barrel,
Sound-absorbing material is filled between outer barrel and inner cylinder, punching blowout waste gas, is then absorbed by sound-absorbing material.
But because the length between outer barrel and inner cylinder is not fixed, the sound-absorbing material of filling is not also fixed, and causes sound absorber
Sound-absorbing effect is uneven caused by material, and the thin local sound-absorbing effect of sound-absorbing material is low；Furthermore muffler is directly installed on offgas duct
At road, the machine oil part of engine can be flowed out with waste gas out of muffler, and muffler is polluted.
The content of the invention
In view of the shortcomings of the prior art, the muffler that a kind of noise reduction is uniform, prevents pollution is now provided.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of muffler, including interior conduit and outer tube
Road, it is characterised in that：Said inner tube road is installed in Outer Tube, is noise reduction layer between said inner tube road and Outer Tube, described outer
Pipeline is made up of the horizontal tube and arc convex pipe being spaced, and multiple punchings, the boss pair are offered on said inner tube road
Punching quantity is less than the quantity of punching at interior conduit corresponding to horizontal tube at the interior conduit answered, and said inner tube road left end is air inlet
Mouthful, said inner tube road right-hand member is gas outlet, and the air inlet is connected with waste pipe, and tail is coated with the gas outlet
Gas blowout pipe.
Further, multiple steam vents are offered on the Outer Tube horizontal tube.
Further, said inner tube road is longer than Outer Tube.
Further, the exhaust nozzle upper end is provided with sector open, and the exhaust nozzle lower end is circular groove.
Beneficial effects of the present invention are as follows：
（1）The present invention is by near interior conduit with a distance from from Outer Tube, that is, punching is set up in the few place of sound-absorbing material, is made
It is uniform to obtain noise reduction；
（2）The present invention can be discharged the gas between Outer Tube and interior conduit by opening up steam vent on Outer Tube, it is therefore prevented that
Exhaust sound is empathized in Outer Tube；
（3）The present invention oil droplet being subjected in interior conduit, is prevented in interior conduit by installing jet pipe in interior conduit gas outlet
Oil droplet be dropped on muffler, pollute.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book understands other advantages and effect of the present invention easily.
As shown in figure 1, a kind of muffler, including interior conduit 2 and Outer Tube 1, interior conduit 2 are installed in Outer Tube 1, inner tube
It is noise reduction layer 7 between road 2 and Outer Tube 1, noise reduction layer 7 is acoustical cotton, and Outer Tube 1 is by the horizontal tube 4 and arc convex pipe 3 that are spaced
Form, offer multiple punchings 6 on interior conduit 2, the quantity of punching 6 is less than the correspondence of horizontal tube 4 at interior conduit 2 corresponding to raised pipe 3
Interior conduit 2 at punching 6 quantity, discharged that noise reduction caused by packing material thickness difference is poor, and the left end of interior conduit 2 is air inlet
11, the right-hand member of interior conduit 2 is gas outlet 12, and air inlet 11 is connected with waste pipe, and tail gas spray is coated with gas outlet 12
Pipe 8.
Multiple steam vents 5 are offered on the horizontal tube 4 of Outer Tube 1, the gas between Outer Tube and interior conduit can be discharged, can
Prevent exhaust sound from being empathized in Outer Tube.
Interior conduit 2 is longer than Outer Tube by 1.
The upper end of exhaust nozzle 8 is provided with sector open 9, and the lower end of exhaust nozzle 8 is circular groove 10, and engine interior point is oily
Drop, as waste gas is discharged, exhaust nozzle 8 is installed in muffler gas outlet 12, the oil to drip can be accepted in groove 10, prevented
Oil droplet is flowed to outside hush pipe.
Above-described embodiment is presently preferred embodiments of the present invention, is not the limitation to technical solution of the present invention, as long as
The technical scheme that can be realized on the basis of above-described embodiment without creative work, it is regarded as falling into patent of the present invention
Rights protection scope in.
