Description
Technical field
The utility model relates to a kind of silencing apparatus, particularly relates to the industrial silencing apparatus that a kind of one-level is eliminated the noise and secondary noise reduction is integrated.
Background technique
The device of the reduction noise on the air-flow path that silencing apparatus is mounted in air powered equipment (as blower, centrifugal blower, air compressor, ventilator, generator) or in inlet and exhaust system.Silencing apparatus can stop sound wave propagation, and allowing air-flow to pass through, is the effective tool of control noises.Existing silencing apparatus has employing separate type, but there is bulky, that erasure effect is not good problem.
Model utility content
In view of this, the purpose of this utility model is to provide the integrated silencing apparatus of a kind of one-level secondary noise reduction, to solve deficiency of the prior art.
In order to achieve the above object, the purpose of this utility model is achieved through the following technical solutions:
The silencing apparatus that the noise reduction of a kind of one-level secondary is integrated, wherein, comprise first order baffler and second level baffler, described first order baffler comprises two column casings, described second level baffler comprises tubular and the first order silencing pot of parallel in the axial direction storing and second level silencing pot, and described first order silencing pot and described second level silencing pot are between two described column casings;
Described first order silencing pot has the first hush tube, described second level silencing pot has the second hush tube and the 3rd hush tube, and described first hush tube, described second hush tube and described 3rd hush tube are parallel to each other and at the radial alternate of described first order silencing pot or described second level silencing pot.
The silencing apparatus that the noise reduction of above-mentioned one-level secondary is integrated, comprises further, and the barrel of two described column casings is provided with sound-absorbing material.
The silencing apparatus that the noise reduction of above-mentioned one-level secondary is integrated, comprises further, and the axis of described first hush tube, described second hush tube and described 3rd hush tube forms three articles of seamed edges of an equilateral triangulo column mutually.
The silencing apparatus that the noise reduction of above-mentioned one-level secondary is integrated, comprises further, and the tube wall of described first hush tube, described second hush tube and described 3rd hush tube is equipped with sound-absorbing material.
The silencing apparatus that the noise reduction of above-mentioned one-level secondary is integrated, comprises further, and described first order silencing pot and described second level silencing pot are all located in tubular shade.
Compared with the prior art, the beneficial effects of the utility model are:
Space is more saved than the secondary muffler of separated type in the past, size is substantially identical with common silencing apparatus, but Performance Ratio standard better effects if, 8-10 decibel can be reduced through experiment proof, this device has been used on ultra-quiet type diesel generating set in a large number, has good using effect.
Accompanying drawing explanation
The accompanying drawing forming a part of the present utility model is used to provide further understanding of the present utility model, and schematic description and description of the present utility model, for explaining the utility model, is not formed improper restriction of the present utility model.In the accompanying drawings:
Fig. 1 is the integrated acoustic wave filter structure schematic diagram of the utility model one-level secondary noise reduction;
Fig. 2 is the sectional view along A-A line in Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
It should be noted that, when not conflicting, the embodiment in the utility model and the feature in embodiment can combine mutually.
See figures.1.and.2, the integrated silencing apparatus of the utility model one-level secondary noise reduction comprises first order baffler and second level baffler, first order baffler comprises two column casings 1, second level baffler comprises tubular and the first order silencing pot 2 of parallel in the axial direction storing and second level silencing pot 3, and first order silencing pot 2 and second level silencing pot 3 are between two column casings 1.First order silencing pot 2 has the first hush tube 4, second level silencing pot 3 has the second hush tube 5 and the 3rd hush tube 6, first hush tube 4, second hush tube 5 and the 3rd hush tube 6 and to be parallel to each other and at the radial alternate of first order silencing pot 2 or second level silencing pot 3.
In present embodiment, the barrel of two column casings 1 is provided with sound-absorbing material, first order silencing pot 2 and second level silencing pot 3 are all located in tubular shade 7 in addition, first hush tube 4, the axis of the second hush tube 5 and the 3rd hush tube 6 forms three articles of seamed edges of an equilateral triangulo column mutually, the wind trap that several hush tubes are staggered formed diametrically, add the distance that wind is walked in vent passages, and wind facies has transverse movement again for first order silencing pot 2 and the existing radial motion of second level silencing pot 3, thus make the contact between wind and silencing apparatus more abundant, therefore when ensureing to ventilate, soundproof effect is more effective.
The tube wall of the first hush tube 4, second hush tube 5 and the 3rd hush tube 6 is also equipped with sound-absorbing material, select sound-absorbing material, first the material meeted the requirements should be determined from sound absorption characteristics aspect, also in conjunction with the requirement such as fire prevention, moistureproof, mothproof, intensity, outward appearance, building interior finishing, to consider and select simultaneously.The sound-absorbing material that can adopt in the present embodiment comprises porous material, as glass wool, slag wool, foamed plastics, felt etc.
As can be seen from above-described embodiment, advantage of the present utility model is:
Space is more saved than the secondary muffler of separated type in the past, size is substantially identical with common silencing apparatus, but Performance Ratio standard better effects if, 8-10 decibel can be reduced, this device has been used on ultra-quiet type diesel generating set in a large number, has good using effect.
Be described in detail specific embodiment of the utility model above, but the utility model is not restricted to specific embodiment described above, it is just as example.To those skilled in the art, any equivalent modifications and substitute also all among category of the present utility model.Therefore, not departing from equalization conversion done under spirit and scope of the present utility model and amendment, all should be encompassed in scope of the present utility model.
