Embodiment 1

[0030] The silent machine room is a closed square room surrounded by the ceiling and the outer wall 1 of the machine room. In the silent machine room, two inner walls 2 of the machine room are set corresponding to the outer wall 1 of the machine room. 4. At least 3 soundproof grilles 5 are installed in each of the air inlet shaft 3 and the exhaust shaft 4 to form an S-shaped air duct of the sound insulation grille group. Between the air inlet shaft 3 and the exhaust shaft 4 is the inner room of the silent machine room The inner room is provided with a shock-absorbing support 13, and a silent box 11 is arranged above the shock-absorbing support 13, and a diesel generator set is arranged in the quiet box 11, and an engine muffler 9 is arranged on the exhaust pipe of the diesel generator set; Air intake louvers 6 are respectively arranged under the inner wall 2 of the machine room, and exhaust louvers 7 are arranged above the outer wall 1 of the machine room of the exhaust shaft 4...

Embodiment 2

[0032] The air enters the air intake shaft 3 from the air intake louvers 6 above the outer wall 1 of the machine room, and enters the inner room of the mute machine room from the air intake louvers 6 below the air intake shaft 3 through the S-shaped air duct of the sound insulation grille group, and enters the inner room of the mute machine room from the upper side of the mute box 11. The air intake hole 12 enters the mute box 11 to supply the diesel generator set, and the hot air and exhaust gas discharged from the diesel generator set enter the exhaust shaft 4, and are discharged from the exhaust shutter 7 through the S-shaped air duct of the sound insulation grille group; the equipment in the mute machine room The surface is equipped with sound-absorbing materials to absorb the noise generated by the diesel generator set, reducing the noise outside the silent machine room to below 45dB.

Embodiment 3

[0034] The shock-absorbing support 13 itself has a shock-absorbing function, which minimizes the vibration generated by the diesel generator set and reduces noise simultaneously.

Abstract

The invention discloses an ultra-silent diesel generating set machine room and a noise control method. The ultra-silent diesel generating set machine room is composed of an outer machine room wall, an inner machine room wall, a downcast shaft, an exhaust shaft, a sound insulation plate grid, a downcast air shutter, an exhaust shutter, a smoke exhaust shaft, an engine silencer, a wind scooper, a silent box, an air inlet, a damping support and an access door. Through the multiple sound insulation and sound absorption devices, noise is reduced under 45dB without affecting normal work of a generating set, and therefore the ultra-silent diesel generating set machine room is suitable for schools, hospitals, residences and other environments.

Description

[0001] technical field [0002] The invention relates to the technical field of noise reduction in a silent machine room, in particular to an ultra-quiet diesel generator set machine room and a noise control method. [0003] Background technique [0004] With the development of the economy and the continuous improvement of people's living standards, people's requirements for the environment are getting higher and higher. The environmental pollution of diesel generator sets mainly includes noise and harmful emissions during work. In order to reduce and control emissions, To reduce noise pollution to the environment, developed countries around the world have successively introduced corresponding laws and regulations as compulsory means to limit them. Noise pollution mainly comes from diesel engines and generators. [0005] Schools, hospitals, and residences generally install diesel generator sets in the basement of the same building, so the noise control requirements for g...
