Description
Technical field
The utility model belongs to generating set technical field, more particularly to a kind of engine exhaust system of generating set.
Background technology
Generating set is the plant equipment into electric energy by the energy conversion of other forms, is by dynamical system, control
System, silene system, shock mitigation system, exhaust system composition, are driven by the hydraulic turbine, steam turbine, diesel engine or other dynamic power machines, will
The energy that current, air-flow, fuel combustion or nuclear fission produce is converted into mechanical energy and is transmitted to generator, then is changed by generator
For electric energy, it is output in electrical equipment and uses.
Communication base station generator group is to be located at the area away from power grid such as field high mountain, desert for current portion of base stations,
Power supply situation is extremely unstable, the situation that frequent occurrence of large-area has a power failure, and uses when emergent.Communication base station generator group is usually adopted
Use oil-fired power generating unit.
Operationally noise is very big for oil-fired power generating unit, in order to reduce the influence to surrounding environment, it is necessary to be carried out to noise
Control.In general, in addition to the Induction and exhaust noises and the noise as caused by vibration of cooling system, engine exhaust emission
Very big noise can be produced.If reducing the noise that engine exhaust emission produces, the noise of generating set can be greatly reduced.
Therefore, the exhaust noise of the engine of generating set how is reduced to the full extent, so as to reduce generating set fortune
Noise during row, becomes those skilled in the art's technical problem urgently to be resolved hurrily.
Utility model content
Technical problem to be solved in the utility model is：A kind of engine exhaust system of generating set is provided, can be with
The exhaust noise of engine is reduced, so that noise when reducing generating set operation, environmental protection.
In order to solve the above technical problems, the technical solution of the utility model is：The engine exhaust system of generating set, bag
The first class sound arrester and secondary muffler being cascaded are included, the first class sound arrester is vertically arranged, the secondary muffler water
It is flat to set, first exhaust adapter and expansion joint, the secondary muffler are equipped between the engine and the first class sound arrester
The port of export be connected with second exhaust adapter.
As an improvement the second exhaust adapter is vertically arranged, the second exhaust adapter disappears away from the two level
One end of sound device is connected with tailpipe, and the port of export of the tailpipe is equipped with rainhat.
As a further improvement, the first exhaust adapter, the expansion joint, the first class sound arrester, the two level
Muffler, second exhaust adapter are respectively positioned on the inside of the babinet of the generating set, the tailpipe and the rain-proof
Cap is arranged on the top of the babinet.
As a further improvement, the inner wall of the babinet is equipped with noise reduction layer, the noise reduction layer include sound insulation cotton layer and
At least one layer of acoustical cotton layer, the sound insulation cotton layer are set close to the inner wall of the babinet.
After employing above-mentioned technical proposal, the beneficial effects of the utility model are：
1) since the engine exhaust system of generating set devises the first class sound arrester being cascaded and two level noise reduction
Device, thus slowed down the high temperature and pressure exhaust gas velocity that engine emission comes out using two mufflers, greatly reduce engine
Exhaust noise so that reduce generating set operation when noise, protect environment；Since the first class sound arrester is vertically set
Put, the secondary muffler is horizontally disposed with so that exhaust system connection and reasonable arrangement.Generating set provided by the utility model starts
Machine exhaust system, reduces the exhaust noise of engine, so that noise when reducing generating set operation, protects environment.
2) since the port of export in the tailpipe is equipped with rainhat, it can prevent rainwater from entering exhaust system.
3) due to the first exhaust adapter, expansion joint, the first class sound arrester, the secondary muffler, described
Second exhaust adapter is respectively positioned on the inside of the babinet of the generating set, and the tailpipe and the rainhat are arranged on described
The top of babinet, thus it is not only beautiful, but also convenience in transport.
4) since the inner wall of the babinet is equipped with noise reduction layer, the noise reduction layer includes sound insulation cotton layer and at least one layer of sound-absorbing
Cotton layer, so can at utmost completely cut off, absorption of noise.
