Description
Technical field
The invention discloses a kind of noise reduction computer room, more particularly to a kind of diesel-driven generator denoising device.
Background technology
With the development of society, the raising of living standards of the people, among modern civil buildings, the species of electrical equipment and
Quantity is more and more, and among these electrical equipments, the not only fire-fighting equipment such as fire pump, spray pump is also in need reliable to supply
The life pump of electricity, the electrical equipment such as elevator, to meet the reliability of these equipment electricity consumptions, when municipal power network, can not to provide two-way only
During vertical power supply, it is generally used in the design using method of the diesel generating set as stand-by power supply.Existing diesel generation
Unit computer room noise decibel value can all be more than 100 decibels, and very big influence can be brought to the environment of surrounding.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of minimum diesel oil for not interfering with surrounding environment of noise
Generating set computer room.
In order to solve the above-mentioned technical problem, the invention provides a kind of diesel-driven generator denoising device, including：Air intake noise reduction
Device, the first class sound arrester air draft wind scooper, secondary muffler and air draft muffler composition；It is characterized in that：Set in the air inlet duct
There is suction silencer；The diesel generating set is connected by damping bellows with the first class sound arrester, is set on the first class sound arrester
There is diffuser, one side of diffuser is provided with thermal wall, and thermal wall is fixed and secondary muffler is housed；It is solid on the diesel generating set
Air draft wind scooper is housed surely, is provided with air draft muffler in air draft wind scooper, the first class sound arrester is fixedly installed on silencer wall.
As a further improvement on the present invention, the diesel generating set continuous power is 100kW -1000kW.
As a further improvement on the present invention, the diesel-driven generator denoising device should be arranged on building the first floor, in
Between each layer or basement.
Using said structure, its advantage is：The present invention is using suction silencer, the first class sound arrester, two level noise reduction
The noise reduction process of the noise reducing apparatus large area such as device and air draft muffler, effectively solves existing diesel generating set computer room noise
Decibel value can all be more than 100 decibels, the problem of bringing very big influence to the environment of surrounding.

Diesel generating set 10 to be stated by damping bellows 3 with the first class sound arrester 4 to be connected, the first class sound arrester 4 is provided with diffuser 8,
One side of diffuser 8 is provided with thermal wall 7, and thermal wall 7 is fixed and secondary muffler 5 is housed；It is fixed on the diesel generating set 10
Equipped with air draft wind scooper 9, air draft muffler 6 is provided with air draft wind scooper 9；The first class sound arrester 4 is fixedly installed in silencer wall
On 11, the continuous power of diesel generating set 10 is 100kW -1000kW；The diesel-driven generator denoising device should be arranged on
The first floor of building, middle each layer or basement.
The present invention is using the present invention using the drop such as suction silencer, the first class sound arrester, secondary muffler and air draft muffler
The noise reduction process of equipment of making an uproar large area, diesel generating set noise decibel value is set there was only 50 or so, noise is minimum.
Any diesel-driven generator denoising device using designed by the technical characteristic similar with the present invention will fall into this hair
Within bright protection domain.
