Abstract

The utility model relates to a two-stage silencer for diesel generating set, which comprises an air inlet pipe, an air outlet pipe and a silencing cylinder, wherein the air inlet pipe and the air outlet pipe are respectively fixed at two ends of the silencing cylinder; the silencing cylinder has at least one baffle fixed within, the baffle being provided fixedly with at least one air pipe the central axis of which is parallel to that of the silencing cylinder. The utility model achieves silencing effect by reflection and absorption by the baffle and the gas pipe to attenuate the exhaust noise. The utility model has excellent silencing effect of noise with medium and low frequency; the working efficiency of devices will not be influenced by the mounting of the silencer and the exhaust gas may be discharged smoothly; the utility model has the advantages of small size, easy processing, economic practicability and freedom from regenerated noise etc., and may be used on equipment of high temperature, high velocity and pulse air current etc.

Description

Diesel generating set secondary baffler

Technical field:

The utility model relates to the baffler technical field, particularly diesel generating set secondary baffler.

Background technique:

Along with the progress of science and technology, industrialized production is more and more flourishing, and still, environmental pollution is also more and more serious thereupon, and noise pollution is exactly one of them.A lot of machinery can be sent very big noise in running, general, except the noise of motor or motor generation, toxic emission also can produce very big noise, and big more than the noise of motor and motor generation, becomes the main source of noise in the industrial production.The noise that produces when how to reduce toxic emission becomes a great problem in the modern production.

The model utility content:

The purpose of this utility model is to provide a kind of diesel generating set secondary baffler at the deficiencies in the prior art, and it can control and reduce air power noise effectively, reduces the pollution to surrounding environment.

For achieving the above object, the utility model adopts following technological scheme: it comprises suction tude, outlet pipe and hush pipe, suction tude, outlet pipe are individually fixed in the two ends of hush pipe, and the hush pipe internal fixation has at least one dividing plate, are fixed with at least one breathing pipe on the dividing plate.

The central axis of described breathing pipe is parallel to the central axis of hush pipe.

The utility model utilizes dividing plate and breathing pipe to the reflection and the absorption of waste gas noise, makes it obtain decay, thereby reaches the effect of noise reduction.The utlity model has good in, the low frequency acoustic attenuation performance; After loading onto silencing apparatus, do not influence the working efficiency of equipment, can guarantee that intake and exhaust are unobstructed; Also have simultaneously volume little, be convenient to characteristics such as processing, economical and practical, no regenerated noise, can be used for high temperature, at a high speed, use on the equipment such as pulse pneumatic.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is that the A-A of Fig. 1 is to schematic representation.

Embodiment:

See accompanying

drawing

1,2, the utility model comprises suction tude 1, outlet pipe 2 and hush pipe 3, and suction tude 1, outlet pipe 2 are individually fixed in the two ends of hush pipe 3.

Described hush pipe 3 adopts cylindrical tube.

Described suction tude 1 and outlet pipe 2 are connected with external mechanical by flange.

Described hush pipe 3 internal fixation have at least one dividing plate 4, are fixed with at least one breathing pipe 5 on the dividing plate 4.

The central axis of described breathing pipe 5 is parallel to the central axis of hush pipe 3.

The utility model adopts a dividing plate 4 that hush pipe 3 is separated into left and right sides two-part, is fixed with six roots of sensation breathing pipe 5 on the dividing plate 4; For having good aerodynamic quality, also promptly load onto silencing apparatus after, the drag losses that is increased do not influence equipment working efficiency, can guarantee that intake and exhaust are unobstructed, the central axis of each root breathing pipe 5 all is parallel to the central axis of hush pipe 3.

The utility model is a reactive muffler.The noise sound wave that produces when waste gas is during by the utility model hush pipe 3, and the acoustic reflection echogenicity of some special frequency channel of transmitting along pipeline reduces the output of acoustic energy, makes along the sound wave of pipe transmmision to be absorbed and to reflect and decay, thereby reaches the purpose of noise elimination.

The utility model can be used on diesel generating set and other machinery, have good in, the low frequency acoustic attenuation performance; After loading onto silencing apparatus, do not influence the working efficiency of equipment, can guarantee that intake and exhaust are unobstructed; Also have simultaneously volume little, be convenient to characteristics such as processing, economical and practical, no regenerated noise, can be used for high temperature, at a high speed, use on the equipment such as pulse pneumatic.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
