Abstract
The utility model relates to a silencer for diesel generator sets which are arranged in a center compartment mode. An interlayer arranged all around can serve as a channel for air intake or air exhaust and has the function of sound insulation and sound attenuation. An insulation baffle can be added on the channel for air exhaust according to need to prolong emptying travel and increase the effect of noise reduction.
Description
The present invention relates to silencing apparatus, particularly a kind of silencer that is suitable for the employing of internal combustion engine generator group.
Noise pollution has become the problem of people's growing interest, and is the generator set of power with the internal-combustion engine, as a kind of easy to use, flow or the power supply of emergency, also be people produce and live in requisite.In order to obtain a kind of low noise internal combustion engine generator group, generally be unit to be placed on an inside be lined with in the single-layer metal railway carriage or compartment of sound absorbing material, heat and waste gas for discharging internal combustion engine process generates need be installed on envelope, air bells exhauster.But just the noise standard of internal-combustion engine finished product permission at present adds noise enterprising, air bells exhauster (though may have silencing apparatus).Even adopt the envelope of sound absorbent of inner liner, its overall noise level also is difficult to be reduced to below 75 decibels.
The object of the present invention is to provide a kind of new silencer, it can satisfy internal combustion engine generator group proper functioning, prevent the necessary ventilation of high temperature rise, the noise level in the time of can reducing this unit work again effectively.
Further aim of the present invention provides the silencer that a kind of internal combustion engine generator group of compact structure is used, by rational deployment, make full use of the space and make necessary ventilation system have the function of sound insulation, sound-absorbing and damping sound-deadening simultaneously concurrently.
An other purpose of the present invention provides a kind of existing means of transportation that is particularly suitable for installing, and for example installs the silencer that the internal combustion engine generator group on the automobile is adopted.
This realizes by following proposal.To be placed in the central compartment intake grill and interior exhaust port in appropriate location offers as the internal combustion engine generator group of noise source.Outer periphery at this central authorities' compartment is equipped with air intake passage and the ventilation channel that plays sound insulation, noise elimination effect simultaneously; relatively have away from the far-end of the passage of interior intake grill, interior exhaust port the external air inlet mouth that communicates with ambient atmosphere and outside exhaust port.The barrier plate also can be set on demand going on ventilation channel,, on passage, also can adopt existing sound-absorbing in the prior art and reduce the measure of noise in order further to increase sound insulation and noise elimination effect into the returning type passage.
Below in conjunction with accompanying drawing, the present invention is done to describe further with embodiment's form.
Fig. 1 is the longitudinal profile schematic representation according to most preferred embodiment of the present invention.
Fig. 2 is quite at the sectional drawing of Figure 1A-A position.
Fig. 3, Fig. 4 are the generalized sections among other two kinds of embodiments similar to Fig. 2 of position.
Fig. 5, Fig. 6 are other two kind embodiments' similar to Fig. 1 longitudinal sectional drawings.
Fig. 7 is all adoptable partial cross section schematic representation of all passages.
In each figure, act on identical part and all adopted identical label as far as possible.
One is that the generator set 1 of power is fixed among the central compartment 2 with the internal-combustion engine, in order to make the unit proper functioning, then need introduce fresh air and discharging waste gas simultaneously.Intake grill 3 on the sidewall of central compartment 2, having.Around the peripheral disposition of sidewall air intake passage 4 is arranged, communicate with ambient atmosphere by the external air inlet mouth 11 on the peripheral railway carriage or compartment wall 5.
During work, can be by internal-combustion engine itself, the air cooling equipment suction air inlet such as at air-cooled engine self device also can as required in position be provided with blower fan 6 such as interior intake grill 3 places at central compartment, facilitates air intake.
In central authorities' compartment 2, relatively away from the appropriate location of interior intake grill 3, for example shown in Fig. 1,5,6, exhaust port 10 in top or bottom are provided with.It reaches by ventilation channel 7 and is connected with ambient atmosphere away from outer exhaust port 8 interior exhaust port 10, that be arranged on the peripheral tank wall 5 relatively.Can set up barrier plate 9 as required on ventilation channel 7, the returning type ventilation channel to go into double-deck and even multilayer can prolong the stroke of exhausting air before atmosphere is advanced in final discharging, like this so that increase the attenuation to noise.
In order to improve isolated and damping vibration attenuation effect to noise, effectively reduce noise level to reach, known various oise-reducing means in the prior art can be set on passage.Such as additional silencing apparatus, and around passage, lay porous sound absorbing material 12 or the like.
As required, can also conversion advance, the ventilation channel spatial arrangement, and the position of import and export separately and quantity.
Self-evident, here the embodiment who provides is just in order to specify conception of the present invention, is not in order to limiting scope of the present invention, and those skilled in the art are according to aim of the present invention in any related domain, can both make multiple conversion and modification, but these all do not surpass scope of the present invention.
Claims (5)
1, a kind of silencer that supplies the internal combustion engine generator group to use, by central compartment for placement internal combustion engine generator group, composition such as air intake passage and ventilation channel, the appropriate location that it is characterized in that said central compartment has intake grill and exhaust port, they play sound insulation, noise elimination effect when being arranged at this compartment periphery, and air intake passage that is communicated with ambient atmosphere and ventilation channel.
2, according to the said silencer of claim 1, it is characterized in that said central compartment can be a hexahedron, wherein have interior intake grill 3 on a sidewall, at least three outer periphery is equipped with air intake passage 4 in the sidewall of said hexahedron four sides, is locating to have external air inlet mouth 11 on the peripheral railway carriage or compartment wall 5 away from the passage outer end of interior intake grill 3 relatively; Exhaust port 10 in having in central compartment by ventilation channel 7, is linked to each other with ambient atmosphere by outer exhaust port 8.
3, according to claim 1 or 2 said silencer, it is characterized in that to be provided with barrier plate 9 in the said ventilation channel.
4, according to claim 1 or 2 said silencer, it is characterized in that can saidly advance, ventilation channel around lay the porous sound absorbing material and in this passage, set up silencing apparatus.
