Description

Noise reduction device for special generator set

Technical Field

The utility model relates to a device of making an uproar falls for special type generating set.

Background

When the engine assembly is in use, a large amount of gas is generated, a certain amount of noise is generated by the gas which is exhausted violently outwards, and in order to reduce the influence of the noise on personnel, a noise reduction device is often needed to be used for carrying out noise reduction treatment on the exhausted gas.

The silencer is used for the airflow pipeline with noise transmission, and can attenuate or reflect the noise in the pipeline by using noise reduction devices such as pipelines and elbows with sound absorption linings or pipelines with suddenly changed sectional areas and other discontinuous acoustic impedances.

The common noise reduction device is a pore plate which has the characteristics of strong noise reduction capability, simple structure and low cost. However, the existing orifice plate noise reduction device is often heavy and has a large volume.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, and providing a noise reduction device which is convenient to connect and used for a special generator set.

The utility model provides a device of making an uproar falls for special type generating set, includes the outer tube, the both ends of outer tube link respectively has go-between and amortization stopper, and the inside of outer tube is equipped with the spiral board, the spiral board be the inside that the heliciform is located the outer tube, the middle part of spiral board is equipped with main inner tube, the round of main inner tube is equipped with the branch inner tube that a plurality of is circumference array distribution around, the branch inner tube pass the spiral board, the pipe wall of outer tube, main inner tube and branch inner tube on all be equipped with the through-hole that a plurality of is circumference array distribution.

Preferably, the outer end face of the spiral plate is connected with the inner wall of the outer pipe.

Preferably, the number of the branch inner tubes is six.

Preferably, the connecting ring is annular.

Preferably, the outer surface of the connection ring is provided with a thread.

Preferably, the diameter of the through hole on the outer pipe is larger than that of the through hole on the main inner pipe, and the diameter of the through hole on the main inner pipe is larger than that of the through hole on the branch inner pipe.

Preferably, the material of the main inner pipe is brass.

Has the advantages that:

in the device, a mode of combining the main inner pipe and the inner pipe is adopted, so that a plurality of silencing pipes are comprehensively arranged in the inner pipe, and the noise reduction capability of the noise reduction device is enhanced.

When the device is used, a large amount of tail gas generated by the special generator set is guided out through the drainage effect of the spiral plate, the flow rate of the tail gas can be gradually reduced through the spiral plate, the noise of the tail gas generated by the special generator set can be reduced to the minimum through the noise reduction effect of the inner pipe, and the noise reduction capability of the whole noise reduction device is greatly improved.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 1-2, the noise reduction device for the special generator set comprises an outer tube 2, wherein two ends of the outer tube 2 are respectively connected with a connecting ring 1 and a silencing plug 3, the connecting ring 1 is annular, and the outer surface of the connecting ring 1 is provided with threads.

The inside of outer tube 2 is equipped with the spiral board, spiral board 6 be the heliciform and be located the inside of outer tube 2, the outer terminal surface of spiral board 6 links to each other with the inner wall of outer tube 2.

The middle part of spiral plate 6 is equipped with main inner tube 4, and the round of main inner tube 4 is equipped with six branch inner tubes that are circumference array distribution around, interior pipe pass the spiral plate, the pipe wall of outer tube 2, main inner tube 4 and interior pipe 5 on all be equipped with the through-hole that a plurality of is circumference array distribution, the through-hole diameter is greater than the through-hole diameter on main inner tube 4 on outer tube 2, the through-hole diameter on main inner tube 4 is greater than the through-hole diameter on the branch inner tube 5.

When using, a large amount of tail gases that special generating set produced are outwards derived through the drainage effect of spiral plate 6, and the flow rate of tail gas can be reduced gradually to spiral plate 6 to through the effect of making an uproar of falling of inner tube 5, can fall to the tail gas noise that special generating set produced to minimumly, thereby promote the ability of making an uproar of falling of whole noise reduction device greatly.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
