Description
Technical field
The utility model relates to silencer fields, and in particular to a kind of foamed aluminium two-phase gas release silencer.
Background technique
The positions such as air reservoir bottom blow-down mouth, cooling driers discharge outlet, steam tank bottom sewage draining exit are discharged
Medium be all the high gas-liquid medium of pressure.Medium is sucked out surrounding air volume with pouring atmosphere at a high speed, empty around disturbance
Gas forms noise, and sound moves rate and pollutes the environment at 90 decibels or more, is detrimental to health, and discharge medium speed is faster,
Noise is bigger, and since the technical difficulty for administering this noise like is larger, there are no mature silencers can be used so far.
It is entitled " a kind of application No. is 201210372360.5, applying date 2012.09.29 in existing patent
The underwater units and its method of foamed aluminium noise elimination, draining ", which is directly arranged flue for foamed aluminium, passes through loudspeaker
Shape slows down the flow velocity of liquid, then is discharged after foamed aluminium noise elimination, also utilizes the inside tortuous passageway structure of foamed aluminium
Carry out noise elimination processing.However, the flow velocity due to liquid is excessive, it can be first to foamed aluminium when actually liquid reaches tubaeform foamed aluminium
It is impacted, to be easily destroyed the internal structure of foamed aluminium, is minimized the acoustic attenuation performance of foamed aluminium, service life subtracts
Short, further, the channel gross area inside the foamed aluminium of horn shape is less than horn shape aisle spare, for liquid kinetic energy
Consumption effect it is obvious, but it is general for the pressure energy of two-phase gas consumption effect.
Summary of the invention
The purpose of this utility model is that: in view of the above problems, the utility model provides a kind of foamed aluminium two-phase
Gas release silencer solves existing two-phase discharge medium noise using the special construction of silencer seat and foam aluminum tube
Handle problem.
The technical solution adopted in the utility model is as follows:
The foamed aluminium two-phase gas release silencer of the utility model, including air inlet pipe and silencer seat, the air inlet pipe
It is connect with silencer seat, foam aluminum tube is installed, the silencer seat is from air inlet pipe to seam allowance on the seam allowance of the silencer seat
The pipeline area at place is gradually increased, and gas containing liquid enters silencer seat from air inlet pipe, then is discharged from foam aluminum tube.
Further, the foam aluminum tube is tubular structure.
Further, it can be closed at the end outlet of the tubular structure.
Further, the foam aluminum tube is pressed on silencer seat with flange, the seam allowance and flange of the silencer seat
Between with flat muscle be connected.
Further, the flat muscle is four.
In conclusion by adopting the above-described technical solution, the beneficial effects of the utility model are:
1, foam aluminum tube is installed on silencer seat, it is tortuous, curved inside foam aluminum tube when two-phase medium passes through foamed aluminium
Bent aperture consumes pressure energy, makes pressure reduction, medium velocity is greatly reduced, to reach good noise elimination effect.
It 2, is that discharge area is greater than inlet -duct area by the structure setting of silencer seat, to work as two-phase gas from air inlet pipe stream
When entering silencer seat, enlarged-diameter, flow velocity is reduced, then when reaching foam aluminum tube, can not only reduce the impact to foam aluminum tube,
Foam aluminum tube is protected, is prolonged the service life, additionally it is possible to so that gas-liquid medium is passed through foam aluminum tube at a slow speed, it is made to obtain sufficient noise
It is then exhausted from after processing, so that noise treatment effect is more preferable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model Foamed-aluminum silencer；
Fig. 2 is the diagrammatic cross-section of the utility model foam aluminum tube.
Marked in the figure: 1- flange, 2- foam aluminum tube, 3- silencer seat, 4- inlet tube.
Specific embodiment
With reference to the accompanying drawing, the utility model is described in detail.
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain
The utility model is not used to limit the utility model.
As depicted in figs. 1 and 2, the foamed aluminium two-phase gas release silencer of the utility model, including air inlet pipe 4 and noise elimination
Device seat 3, the air inlet pipe 4 are connect with silencer seat 3, and foam aluminum tube 2 is equipped on the seam allowance of the silencer seat 3, described to disappear
Pipeline area of the sound device seat 3 from air inlet pipe 4 to stop portion is gradually increased, thus when gas containing liquid flows into silencer from air inlet pipe 4,
Enlarged-diameter, flow velocity reduce, then when reaching foam aluminum tube, can not only reduce the impact to foam aluminum tube, protect foam aluminum tube,
Prolong the service life, additionally it is possible to so that gas-liquid medium is passed through foam aluminum tube at a slow speed, is then exhausted from after so that it is obtained sufficient noise treatment,
To which noise treatment effect is more preferable.
Further, foamed aluminium is various shape can be made, the use of the new type is in the recent period come the new material to grow up
Tubular structure is made in foamed aluminium, there is small size tunnel that is tortuous, being bent, interpenetrate, the small size tunnel gross area inside foamed aluminium
Decades of times bigger than the circulation area of pipe.When two-phase medium passes through foamed aluminium, the airflow direction for flowing into foamed aluminium is intricate, mutually
It mutually interferes, tortuous, curved aperture consumes pressure energy, makes pressure reduction, speed is greatly reduced.When two-phase medium (generally with
Based on gas) it is diffused by foam aluminum tube, when gas-liquid medium flows into atmosphere from tube wall surrounding, speed can be down to very low, noise
It is reduced, not recontamination environment, plays noise elimination.Preferably, can be closed at the end outlet of tubular structure, thus gas-liquid
Medium is discharged to atmosphere again after capable of obtaining sufficiently processing from foamed aluminium tube wall and top closed structure.Simultaneously as tubulose
The setting of structure, foam silencer can work normally under any ratio of gas-liquid.
In a preferred embodiment, in order to not influence the noise elimination effect of foam aluminum tube, while to expand to the maximum extent
Big gas-liquid flow leads to area, and the foam aluminum tube 2 is pressed on silencer seat 3 with flange 1.Further, the silencer seat 3 only
It is connected between mouth and flange with four flat muscle, flange can be firmly secured on seam allowance by flat muscle, so that foam aluminum tube is steady
Surely it is fixed on silencer seat, avoids two-phase gas that foam aluminum tube impact falls off.
A kind of foamed aluminium two-phase gas release silencer provided by the utility model is described in detail above.
Specific embodiment used herein is expounded the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model.It should be pointed out that being led for this technology
For the those of ordinary skill in domain, without departing from the principle of this utility model, if can also be carried out to the utility model
Dry improvement and modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
