Abstract
A high-efficiency energy-saving multistage blades type silencer of a combustion engine mainly comprises an air inlet pipe, an inner silencing barrel, an outer silencing barrel and an air discharging pipe. Three-stage blades are arranged inside the inner silencing barrel and fixed on a blade shaft which is connected with a generator. Exhaust air flows from the air inlet pipe and passes through the three-stage blades in the silencing barrel, the blades revolve under the inertial driving of the exhaust air, and electrical energy is generated by the generator through transmission of the blade shaft. Air flow is divided into multiple currents of small air flow, parts of noises are absorbed by sound deadening coatings on the blades, and then the air flow flows towards an inner cavity of the outer silencing barrel through silencing holes at the middle and upper portion of the inner silencing barrel, the air flow form the silencing holes interferes the air flow reflected by the inner wall of the outer silencing barrel, consequently silencing effect is realized, and the air flow is discharged through an air discharging pipe. The high-efficiency energy-saving multistage blades type silencer of the combustion engine has good silencing effect and small air discharging resistance, converts parts of unavoidable air discharging resistance into the electric energy for being accumulated, thereby obtaining energy saving effect.

Technical field
The utility model relates to a kind of internal combustion engine exhaust silencer, is specifically related to the multistage blade type silencing apparatus of a kind of energy-efficient internal-combustion engine.
Background technique
Existing internal combustion engine exhaust silencer can be divided into dissipative muffler, reactive muffler, impedance composite muffler three classes by noise-cancelling theory and structure.
1. reactive muffler: reactive muffler is that sound wave reflection takes place when propagating and interferes, and reduces acoustic energy and reaches the noise elimination purpose when forming various noise eliminations unit such as expansion chamber, resonant chamber by parts such as pipeline, dividing plates in inside.
2. dissipative muffler: be that filling sucting sound material absorbs the silencing apparatus that acoustic energy reaches the noise elimination purpose around the pipeline that exhaust gas inside is passed through.
3. impedance composite muffler: be the silencing apparatus that constitutes with reactive muffling unit and sound-absorbing material respectively, it has the common feature of resistance, dissipative muffler.Basic, normal, high audio-frequency noise all there is good noise elimination effect.
The prior art shortcoming has:
1. comprehensive above-mentioned three kinds of silencing apparatuss, the noise elimination effect of existing internal combustion engine exhaust silencer is directly proportional with exhaust resistance, and the good more resistance to exhaust of the effect of promptly eliminating the noise is big more, and the energy consumption that resistance increases motor increases, and noise elimination effect and exhaust resistance can't be taken into account;
2. this part exhaust resistance that can't overcome can not obtain utilizing, and all wastes in the noise elimination process.
Summary of the invention
In order to solve above-mentioned technical disadvantages, the utility model discloses the multistage blade type silencing apparatus of a kind of energy-efficient internal-combustion engine.The utility model has following good effect:
1. it is effective to eliminate the noise;
2. there is not complicated resistance noise reduction structure in the silencing apparatus, less to exhaust resistance;
3. convert unavoidable that part of exhaust resistance to electric energy, reach energy-saving effect.
The technical solution of the utility model is: the multistage blade type silencing apparatus of a kind of energy-efficient internal-combustion engine, it comprises suction tude 1, suction tude 1 is connected on interior silencing pot 2 bottoms, interior silencing pot 2 top closure, the middle and upper part of interior silencing pot 2 has many sound attenuation holes 6, outer silencing pot 3 is placed in interior silencing pot 2 outsides, outer silencing pot 3 tops one side joint outlet pipe 9, there are three grade blades 4 interior silencing pot 2 inside, blade 4 is fixed on the sharf 5, sharf 5 passes interior silencing pot 2 successively, outer silencing pot 3, bearing 7 also is connected with the generator 8 that is installed in outer silencing pot 3 upper ends, and bearing 7 is installed in outer silencing pot upper end.
Described blade 4 is made by resistant to elevated temperatures lightweight material, and scribbles sound deadening coating above the blade.
Described bearing 7 can be worked under hot environment, plays support blade axle 5.
Working principle of the present utility model is: the waste gas of internal-combustion engine enters from the suction tude 1 of silencing apparatus, at first by three grade blades 4 in the silencing pot, blade 4 rotates under the promotion of waste gas inertia, pass to generator 8 by sharf 5, produce electric energy, when air communication is crossed each grade blade 4, by the sound deadening coating absorption portion noise that is coated on the blade 4, and blade 4 is divided into the multiply little airflow with air-flow, reduces by current rate behind three grade blades so successively, reaches the noise elimination effect of the first step; Air-flow flows to outer silencing pot 3 inner chambers by the sound attenuation hole 6 of interior silencing pot 2 middle and upper parts again, and air-flow is through the increase frequency of sound attenuation hole 6 back noises, and listened to the composition in the frequency spectrum reduces, and reaches the second step noise elimination effect; The air-flow that comes out from sound attenuation hole 6 collides back reflection with outer silencing pot 3 inwalls, the air-flow that reflects is interfered with the air-flow of going out from sound attenuation hole 6, like this outer wall of interior silencing pot 2 and outside form an acoustic attenuation zone between the inwall of silencing pot 3, reach the 3rd step noise elimination effect, last air communication is crossed outlet pipe 9 and is discharged.
Therefore positive beneficial effect of the present utility model has:
1. eliminate the noise through three steps, the utility model can reach the effect of eliminating the noise preferably;
2. there is not complicated resistance noise reduction structure in the silencing apparatus, less to exhaust resistance;
3. make full use of waste gas inertia and promote blade drive generator, inevitable part exhaust resistance is converted into power storage, reach energy-saving effect.
