Embodiment
In order to understand the technical solution of the utility model better, below by embodiment particularly and be described in detail in conjunction with the accompanying drawings:
See also Fig. 1 and Fig. 2, low noise square compartment power station of the present utility model comprises the shelter 1 of a steel construction, control switch cabinet 2, air intake muffler 3, diesel generating set 4, smoke exhaust pipe 5, air draft muffler 6 and the smoke-discharging noise elimination device 7 of the system integration.
Top the right and left of shelter 1 and side are separately installed with electric-powered shutter as inlet and outlet 12,16, can control into, the direction of air draft; The ceiling of shelter 1 and all be equipped with sound-absorbing material on the inwall all around is made of the rock wool of zinc-plated punching steel plate and interlayer, and its structure and noise reduction and dissipative muffler are suitable.The end face of shelter 1 is coated with flashing board 10.
Smoke-discharging noise elimination device 7 is fixed on by the right-hand member of air draft muffler 6.This smoke-discharging noise elimination device 7 is combined by the ripple shock-absorbing joint, a dissipative muffler and the reactive muffler that are connected on the smoke exhaust pipe 5, the difformity that this reactive muffler is connected successively by plurality of sections or the pipeline of changes of section constitute, reflection and interference effect that the acoustic impedance that causes by means of the variation of pipeline section and shape does not match and produced reach the purpose of attenuate acoustic noise.
The dissipative muffler that air intake muffler 3 and air draft muffler 6 are arranged by the multi-disc lateral separation constitutes, and the arrangement pitch distance of these sheet dissipative mufflers can form 1～2 expansion cavity respectively when being connected with the bottom surface of exhaust outlet 16 is corresponding with air inlet 12; Dissipative muffler is made of the zinc-plated punching steel plate of nexine and the rock wool of interlayer.When noise passed punching steel plate aperture and impacts rock wool or mineral wool, just as promote piston moves, sound wave caused the air in the sound-absorbing material hole and the vibrations of fiber fines.Because friction and viscosity resistance, the kinetic energy that a part of noise energy is become the sound piston consumes, thereby has reduced the outside propagation of a part of noise.Owing to arranged expansion cavity, make noise after through the decay of chip dissipative muffler, produce unmatched reflection of acoustic impedance and interference effect through the expansion cavity expansion again, reach the purpose that noise is decayed again.Simultaneously because advance, the elongation in air draft path, noise is decayed in the process of releasing naturally, increased noise reduction.
Low noise square compartment power station of the present utility model can be guaranteed unit under the condition that satisfies ventilate cooling and exhaust back pressure allowable, is also promptly guaranteeing to reach the effect of low noise work under the prerequisite that the unit full power is exported.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
