Abstract
The utility model relates to a secondary silencer of a generator set. The secondary silencer of the generator set is characterized in that the secondary silencer is provided with a sub silencer body (1); a sub silencer cover (9) is arranged and matched with the sub silencer body (1); the sub silencer body (1) is provided with a gas inlet pipe (2) and a tail pipe (3); the sub silencer body (1) is internally provided with a center spacer (4); through the center spacer (4), the sub silencer body (1) is spaced in to a first cavity (10) and a second cavity (11); one ends of the gas inlet pipe (2) and the tail pipe (3) are respectively penetrated and inserted on the center spacer (4); and the sub silencer body (1) is internally provided with a first inner insertion pipe (5) and a second inner insertion pipe (6) which are respectively penetrated and inserted on the center spacer (4). In the utility model, a resistance expanding type silencer is adopted, thus the obviousness of silencing effect is ensured; and if a good ventilating heat dissipation air flue is matched, the silencing effect can reach less than 85dB (A).
Description
Technical field
The utility model belongs to the generator set technical field, relates in particular to a kind of secondary muffler of generator set.
Background technique
Along with deepening continuously of development of science and technology and basic scientific research, new material and The application of new technique have played bigger impetus to the development of generator set.But the air-cooled generator silencing apparatus of present some noise reduction is not obvious, causes the generator set noise big and influence surrounding environment.
Summary of the invention
The purpose of the utility model is the deficiency to above-mentioned existing technology; A kind of secondary muffler that is used for generator set is provided; The technological scheme that the purpose of realization the utility model is taked is: the secondary muffler of this generator set is provided with
secondary muffler body, cooperates with secondary muffler body to be provided with secondary muffler cover, and secondary muffler body is provided with suction tude and tail pipe; Be provided with central diaphragm in the secondary muffler body; Central diaphragm is spaced apart first cavity and two cavitys of second cavity with secondary muffler body, and an end of suction tude and tail pipe interts respectively on central diaphragm, and the while in secondary muffler body, is provided with first interpolation pipe and second interpolation pipe interts respectively on central diaphragm; For the purpose of firm, first interpolation pipe and second interpolation pipe are respectively equipped with first dunnage and second dunnage is used for supporting.
the utility model adopts resistance expanssion type silencing apparatus, has guaranteed the explicitly of noise elimination effect, if the ventilation and heat air channel of working good can make the noise elimination effect reach below the 85dB (A).
Description of drawings
Fig. 1 is the plan view of the utility model structural representation;
Fig. 2 is the side view of the utility model structural representation.
Among the figure, 1,
secondary muffler body, 2, suction tude, 3, tail pipe; 4, central diaphragm, 5, first interpolation pipe, 6, second interpolation pipe, 7, first dunnage; 8, second dunnage, 9, secondary muffler cover, 10, first cavity, 11, second cavity.
Embodiment
With reference to accompanying drawing; The secondary muffler of this generator set is provided with
secondary muffler body 1, cooperates with secondary muffler body 1 to be provided with secondary muffler cover 9, and secondary muffler body 1 is provided with suction tude 2 and tail pipe 3; Be provided with central diaphragm 4 in the secondary muffler body 1; Central diaphragm 4 is spaced apart first cavity 10 and 11 two cavitys of second cavity with secondary muffler body 1, and an end of suction tude 2 and tail pipe 3 interts respectively on central diaphragm 4, and the while in secondary muffler body 1, is provided with first interpolation pipe 5 and second interpolation pipe 6 interts respectively on central diaphragm 4; For the purpose of firm, first interpolation pipe 5 and second interpolation pipe 6 are respectively equipped with first dunnage 7 and second dunnage 8 is used for supporting.During use, the tail pipe of suction tude 2 and one-level silencing apparatus joins, and the gas of discharging from the one-level silencing apparatus gets into second cavity 11 after suction tude 2; Noise reduces; The part of gas gets into first cavity 10 through first interpolation pipe 5 and second interpolation pipe 6 in second cavity 11, and noise is further reduced, and is last; Gas in first cavity 10 is discharged outside the silencing apparatus through tail pipe 3, and noise is minimized at last.
Claims (2)
1. the secondary muffler of a generator set; It is characterized in that: this secondary muffler is provided with secondary muffler body (1); Cooperate with secondary muffler body (1) and to be provided with secondary muffler cover (9); Secondary muffler body (1) is provided with suction tude (2) and tail pipe (3), is provided with central diaphragm (4) in the secondary muffler body (1), and central diaphragm (4) is spaced apart first cavity (10) and (11) two cavitys of second cavity with secondary muffler body (1); One end of suction tude (2) and tail pipe (3) interts respectively on central diaphragm (4), and the while in secondary muffler body (1), is provided with first interpolation pipe (5) and second interpolation pipe (6) interts respectively on central diaphragm (4).
