In order to solve the above-mentioned technical problem the present invention provides a kind of array type silencer, noise elimination effect is good.
Technical solution used by the present invention solves the above problems is:
A kind of array type silencer, including frame and the noise elimination column being arranged in frame, the noise elimination column is in array
Arrangement, the noise elimination column includes pod, and the pod is partitioned into air inlet pod and out conductance by the first spacing board
Stream cover, is provided with into horn-like inlet cylinder in the air inlet pod, the one end of the inlet cylinder being relatively large in diameter with
The opening of air inlet pod matches and is provided with air-flow through-hole on the lesser one end of diameter, is arranged on first spacing board
There is air-flow through-hole, is provided on the side wall of silencing plate and outlet pod and is provided with inwardly on the inner wall of the outlet pod
Protrusion, be provided with anechoic sheet in the outlet pod, the anechoic sheet is at annular shape and coaxial with outlet pod.
Preferably, being provided with protrusion or/and groove on the anechoic sheet.
Further, the anechoic sheet has multiple, and diameter is different but coaxial.
Preferably, being provided with the second spacing board outside the inlet cylinder, second spacing board is located at inlet cylinder
The lower section of air-flow through-hole.
Further, silencing plate is provided with above second spacing board.
To sum up, the beneficial effects of the present invention are:
1, noise enters in air inlet pod through horn-like inlet cylinder of the invention, realizes that level-one is eliminated the noise；Again through first
Air-flow through-hole on spacing board enters outlet pod, realizes that second level is eliminated the noise；Inside protrusion is set on outlet pod, is increased
The contact area of big air-flow and silencing plate, improves noise elimination effect；Anechoic sheet is provided in outlet pod to inhale noise
It receives, noise elimination effect of the invention is good.
2, anechoic sheet of the invention is circular and coaxial with outlet pod 12, and the noise elimination effect at each position is uniform.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of noise elimination column of the invention.
Label and corresponding parts title in attached drawing: 11, air inlet pod；12, outlet pod；2, the first interval
Plate；3, silencing plate；4, anechoic sheet；5, inlet cylinder；6, the second spacing board.
Specific embodiment
Below with reference to examples and drawings, technical scheme in the embodiment of the invention is clearly and completely described, shows
So, the described embodiment is only a part of the embodiment of the present invention, instead of all the embodiments.Based on the implementation in the present invention
Example, every other embodiment obtained by those of ordinary skill in the art without making creative efforts belong to
The scope of protection of the invention.
Embodiment 1:
A kind of array type silencer as shown in Figure 1, including frame and the noise elimination column being arranged in frame, the noise elimination
Column is arranged in array, and the noise elimination column includes pod, it is characterised in that: the pod is by between the first spacing board 2
It is divided into air inlet pod 11 and outlet pod 12, horn-like inlet cylinder 5, institute are provided with into the air inlet pod 11
It is provided with air-flow through-hole on the lesser one end of state and diameter, is provided with air-flow through-hole on first spacing board 2, it is described
It is provided on the inner wall of outlet pod 12 on the side wall of silencing plate 3 and outlet pod 12 and is provided with inside protrusion, it is described
Outlet pod 12 in be provided with anechoic sheet 4, the anechoic sheet 4 is at annular shape and coaxial with outlet pod 12.
The one end of inlet cylinder 5 being relatively large in diameter and the opening of air inlet pod 11 match, i.e. inlet cylinder 5 is relatively large in diameter
One end shape it is identical as the opening of air inlet pod 11.The present invention has done excellent in the structure that silencer mainly offsets sound column
Change.It sets horn-like for inlet cylinder, enters convenient for wind.Gas turbine, aircraft engine test stand, mine, tunnel, subway,
The wind in the air ducts such as building enters in air inlet pod 11 through horn-like inlet cylinder, realizes that level-one is eliminated the noise；Again through the first spacing board 2
On air-flow through-hole enter outlet pod 12, realize that second level is eliminated the noise.Inside protrusion is set on outlet pod 12, is increased
The contact area of air-flow and silencing plate improves noise elimination effect.It is provided with anechoic sheet in outlet pod 12, and anechoic sheet is set
It is set to annular shape and coaxial with outlet pod 12, keeps the noise elimination effect at each position uniform.The noise elimination column of silencer of the invention
After being installed using 4*4 array arrangement, noise elimination effect can be dropped more than 35 dB (A) by highest noise 110dB (A)
Below to 55 dB of noise figure (A).
Embodiment 2:
A kind of array type silencer as shown in Figure 1, in order to further enhance noise elimination effect, the present embodiment is in existing skill
Optimize on the basis of art, i.e., is provided with protrusion or/and groove on the anechoic sheet 4.On anechoic sheet be arranged protrusion or
Set wavy for anechoic sheet section, the effective contact area for increasing anechoic sheet and wind enhances noise elimination effect.
The quantity of anechoic sheet is more, and noise elimination effect is better, therefore sets multiple for anechoic sheet 4, in order to use gas pod
The diameter of uniform in effect in 12 everywhere, multiple anechoic sheets is different but coaxial.
Embodiment 3:
A kind of array type silencer as shown in Figure 1, in order to further improve noise elimination effect, the present embodiment is in above-mentioned reality
It applies and optimizes on the basis of example, i.e., be provided with the second spacing board 6 outside the inlet cylinder 5, second spacing board 6 is located at
The lower section of the air-flow through-hole of inlet cylinder 5.Noise is obstructed using the second spacing board 6 to flow to 11 opening of air inlet pod.
In order to further improve noise elimination effect, the top of second spacing board 6 is provided with silencing plate.
As described above, the present invention can be realized preferably.
