Description
Technical field
It the utility model is related to a kind of closing space diesel generating set water cooled silencer.
Background technology
The work noise of diesel generating set is a kind of serious environomental pollution source, endangers pole to the physical and mental health of people
Greatly, but because the advantages of diesel generating set is intrinsic, is still applied to all trades and professions more and more widely.With people's environmental consciousness
Generally improve, diesel generating set user is to environmentally friendly requirement also more and more higher, the mute type machine of low-noise environment protection function admirable
The group market demand is increasing always, but due to diesel generating set design feature, this bulk noise is larger, how to realize great drop
It is always the problem for perplexing diesel generating set industry that the amount of making an uproar, which reaches user's acceptable noise requirements,.
Diesel-driven generator can produce very big heat and noise when working, according to the operation principle of fuel engine power generation unit,
The generation of its noise is extremely complex.Divide from Producing reason and position, the noise of fuel engine power generation unit can include following
Several parts：
(1) smoke evacuation noise；(2) mechanical noise；(3) combustion noise；(4) cooling fan and exhaust noise；(5) air intake is made an uproar
Sound；(6) generator noise；(7) other noises.
Diesel engine unit noise is the complicated sound source being made up of a variety of sound sources.Mainly comprising aerodynamic noise, surface
Radiated noise and electromagnetic noise.For the noise of diesel generating set especially based on exhaust noise, noise is in obvious low frequency.Making an uproar
In the case that sound source can not reduce, sound insulation, sound absorption and the comprehensive regulation eliminated the noise can be taken the diesel generating set as needed.
The method for reducing noise is a lot, and most general designs a high-performance unit acoustic hood and high performance exhaust silencer, with
Reduce mechanical noise and exhaust noise；Vibration reducing measure is taken, vibration is reduced, to reduce the production of solid sonic propagation and regenerated noise
It is raw.
But concurrently, need constantly to carry out during diesel generating set normal operation fresh air exchange for radiating and
Burning, body, smoke evacuation system, high speed rotary grinding position, generator windings etc. all can produce big calorimetric, it is necessary to logical during work
Wind radiates, therefore not only to consider the reduction of noise during acoustic hood design, but also to consider air intake, air discharging and radiating etc., and noise reduction will
Ask closed with protecting that enough to enter both exhaust areas be conflicting.If reducing noise, sound insulation cover opening will be smaller,
But opening is too small, and diesel generating set combustion air and ventilation and heat can not meet again, opening is too big, and noise can leak again.
Acoustic hood will consider two aspects of this contradiction when designing.
Using the Jing Yin box structure of totally enclosed type so that unit noise is at utmost isolated with the external world, but need balanced consideration unit
Radiating and ventilation, using full water cooling radiating mode, can make that dress hole need not be opened on casing, to greatest extent ensure noise suppression
System, while fully dissipated because cooling water circulation flows heat in guard box body, ensureing unit appropriate working temperature condition
Maximum noise control can be achieved down.
Exhaust noise in aerodynamic noise caused by diesel engine work is the most prominent, turns into pollution from environmental noise
One of principal element.It is to use exhaust silencer to reduce exhaust noise most efficient method.
Silencer can be divided into dissipative muffler, reactive muffler and impedance muffler by its operation principle.It is resistive to disappear
Sound-absorbing material come abating noises, is fixed on the inner-walls of duct of airflow or by certain way by sound device mainly with sound-absorbing material
Arrangement in the duct, when sound wave enters silencer, most of acoustic energy is absorbed, play noise elimination act on, dissipative muffler it is excellent
Point is to be eliminated the noise in the range of wider medium-high frequency, especially there is prominent noise elimination effect to high frequency sound wave.Shortcoming is in high-temperature water
Steam and there is service life in the gas of corrosion function shorter to sound-absorbing material.It is generally used for family, office's air conditioner；Greatly
Type wind-tunnel, jet engine test cell etc..Reactive muffler is also known as acoustic filter, and it is divided into resonant, expansion chamber again
It is several with interference formula etc..Simplest expansion chamber is that one section of larger extra heavy pipe in section is connect on gas channel pipe, but its terminal
It is tubule, the section button length of regulation expansion chambers (big pipe) is to change the reflection of sound wave and interference performance, so as to change sound deadening capacity
With maximum frequency of noise elimination.It is with dissipative muffler difference without placing sound-absorbing material, reactive muffler it is excellent
Point is simple in construction, the resistance to gas pickling of high temperature resistant, there is good low frequency acoustic attenuation performance, is mainly used in engine and other pistons hair
The air inlet of motivation and exhaust outlet.
Waste gas in diesel generating set after each cylinder operation of engine is sent to blast pipe and silencer, then drains into air
In.Silencer is approached with exhaust gas temperature because of metal material conduction of heat hull-skin temperature when diesel engine works, and about 500
Degree, is very strong thermal source within the enclosed space, can cause closing space thermal accumlation if do not handled, temperature is stepped up, most
Cause generating set can not normal work eventually.
