Description
Technical field
The present invention relates to silencing means field, is specially a kind of microperforated panel muffler.
Background technology
Microperforated panel silencer is the silencer of lining dress microperforated panel structure.Air-flow can be eliminated in wider frequency range
Noise, and have high temperature resistant, resistance to greasy dirt, corrosion resistant performance, even if carrying large quantity of moisture in the gas flow, nor affect on work.
Since penetration hole diameter is small, plate face is smooth, silencer resistance damage is smaller than general dissipative muffler.Disappear to basic, normal, high each frequency band
Volume is more straight, and sound deadening capacity is big, more apparent to low frequency noise elimination effect, suitable for ventilation and air conditioning system, low pressure blower, air
Kinetic noise is eliminated the noise.It is more suitable for the air conditioner systems such as more demanding clean room, desinfection chamber, food hygiene industry, hotel
To unite, orifice plate is fixed with keel inside and outside microperforated panel silencer, by selecting the orifice plate and different cavity deep combination of different punching rates,
Good noise elimination effect can be obtained in wider frequency range.
Microperforated panel muffler is generally made of proof gold metal thin plate of the thickness less than 1mm in the prior art, and thin plate is opened
Porosity is 1%-3%, and small drag losses is 7-30Pa.Sound deadening capacity is 20-25Bb (A) during high frequency, sound deadening capacity 15-25 Bb during low frequency
(A).Since microperforated panel silencer is chiefly used in having the clean room of purity requirements, desinfection chamber, food hygiene industry etc., because
This requires microperforated panel to have moisture-proof dust-proof effect the more demanding of cleanliness factor, in high temperature, high-speed flow and its can have
Applied under the particular surroundings such as steam, greasy dirt, dust.
The content of the invention
To solve the above problems, the invention discloses a kind of microperforated panel muffler.
In order to reach object above, the present invention provides following technical solution：
A kind of microperforated panel muffler, including air inlet pipe, casing, air outlet pipe, described sleeve pipe side is equipped with air inlet pipe, another
Side is equipped with air outlet pipe, and described sleeve pipe is divided into first chamber, second chamber, the 3rd chamber, institute by first partition and second partition
State and through hole is equipped with first partition and second partition, the air inlet pipe is through first partition, second partition and is fixedly connected on
On the edge of through hole, the air outlet pipe is through first partition, second partition and is fixedly connected on the edge of through hole, the air inlet
Micropunch is equipped with tri- chambers of Guan, the air outlet pipe is equipped with micropunch in first chamber；The air inlet pipe with it is described go out
Hush pipe is additionally provided between tracheae, the hush pipe is through first partition, second partition and is fixedly connected on the edge of through hole,
The hush pipe is equipped with micropunch in first chamber, the 3rd chamber, and microperforated panel is equipped with the hush pipe；Described sleeve pipe
Inner side is equipped with noise reduction layer.
Further, the air outlet pipe is equipped with filter layer in the 3rd chamber, and the filter layer is made of active carbon layer.
Further, the noise reduction layer is made of silencing cotton.
Further, the air inlet pipe in the first chamber, hush pipe, the micropunch that sets in air outlet pipe shift to install；
The indoor air inlet pipe of 3rd chamber, hush pipe, the micropunch that sets in air outlet pipe shift to install.
Further, the aperture of the micropunch is 10-30mm, and the spacing between the micropunch is 10-30mm.So set
Put is to farthest utilize microporous pipe surface area, reach best aperture erasure effect.
Further, the length that the air inlet pipe is inserted into the 3rd chamber is the 1/2 of the 3rd chamber axial length, the outlet
The length of pipe insertion first chamber is the 1/2 of the 3rd chamber axial length.
The course of work and operation principle of the present invention：After exhaust gas enters the 3rd chamber by air inlet pipe, pass through air inlet pipe
Micropunch enters the 3rd chamber, and the micropunch subsequently into hush pipe enters first chamber, from the 3rd indoor hush pipe of chamber
Enter first chamber in micropunch, air outlet pipe is then entered by the micropunch of air outlet pipe, the filter layer filtering heel row through air outlet pipe
Go out.Noise reduction layer and micropunch first through the 3rd chamber carry out noise reduction, utilize resistance noise reduction and microperforated panel noise-cancelling theory so that
Noise in exhaust gas rubs in hole and changes into thermal energy consumption and dissipate, and weakens exhaust gas noise sound wave, eliminates wherein most
High-frequency noises.Exhaust gas enters the micropunch of hush pipe being connected with the 3rd chamber through the 3rd chamber afterwards, on hush pipe
It is covered with micropunch, exhaust gas utilization micropunch noise-cancelling theory, the middle low-frequency spectra in waste gas noise will shift to high frequency and hyperfrequency,
Noise substantially reduces, and the microperforated panel in hush pipe has the effect for effectively removing noise.At the same time first chamber noise reduction layer and
Micropunch continues to eliminate the high-frequency noises in waste gas noise, is finally discharged from air outlet pipe.Whole process employ resistive noise reduction,
Microperforated panel noise reduction, aperture noise reduction and the combination of resistant noise-reducing mode, the low frequency in waste gas noise and high-frequency noises is effective
Remove.While noise is removed, without using resistive filler, when work, does not play dirt, is not afraid of mist of oil, aqueous vapor, high temperature resistant is corrosion-resistant
Impacted with high-speed flow, there is moisture-proof dust-proof effect, the place for being very suitable for high cleanliness requirement uses.Air inlet pipe is micro- at the same time
Perforation realization is uniformly distributed exhaust gas, diffusing air current, further effective noise reduction.
In conclusion it is an advantage of the invention that：1st, the present invention has good sound deadening, and good muffling effect；2nd, exist
There is cooling, dust-proof effect while effective noise reduction, while settle the effect of dust；3rd, the apparatus structure is simple, easy to use,
Without artificially safeguarding after input, economic value is high, and cost is low.
