Abstract
The utility model discloses a muffler for a great air-delivery chimney. The muffler includes an inlet and a housing. The housing is equipped with an inner container with holes. The inner container is connected to the housing through a support device. The housing fixedly connects with the inlet as a whole. When noise caused by great air-delivery enters into a muffling barrel which is the inner container, the original frequency of the noise is changed. Then the noise is distributed through the holes in the muffling barrel and discharged into the air through an air outlet of the muffler. Thus, the aim of muffling is achieved.
Description
Technical field
The utility model relates to a kind of noise silencing equipment, particularly a kind of especially big air quantity chimney muffler that is mainly used in coking industry, thermal power generation industry, large-sized boiler, capacity coke oven cleaning shaft and chimney.
Background technology
Because the import and export air quantity of coking industry, thermal power generation industry, large-sized boiler, capacity coke oven cleaning shaft and chimney is big, reaches 18-45 ten thousand m
3/ h, the noise that blower fan produces is also big especially, and particularly concerning the people around the accommodation, have the greatest impact evening, and the muffling device that general blower fan is joined can not satisfy noise noise reduction requirement, and how to abate the noise has become people's consideration and long-term indeterminable problem.
Summary of the invention
The purpose of this utility model provides a kind of large-scale air quantity noise muffler.
For achieving the above object, the technical solution adopted in the utility model is:
Especially big air quantity chimney muffler, comprise muffler import and silencer casing, it is characterized in that: the muffler inner bag is set in the silencer casing, on the muffler inner bag aperture is set, the muffler inner bag links to each other with silencer casing by bracing or strutting arrangement, and silencer casing and silencing end are connected to one.
Hole diameter is ￠ 3-5mm on the described muffler inner bag, and bracing or strutting arrangement is the muffler connecting plate.
Described silencer casing is a cylindrical structural, silencer casing links to each other with the muffler import by flange, the muffler import is circular port and leads to the muffler inner bag, the muffler inner bag is opening of import, the enclosed cylinder barrel in other end, silencing end are that cylindrical staving and silencer casing are welded to connect.
Described silencer casing is the cylinder staving of ￠ 1000-28000mm diameter.
The utility model has the following advantages and effect with respect to prior art:
1, handles big 18-45 ten thousand m of air quantity
3/ h has solved large-scale pipeline noise reduction and the big problem of chimney noise.
2, simple in structure, no complex structural member.
3, easy for installation, can install behind the big blower fan or on the chimney.
4, elimination gives great volume, and can reduce noise 25-40 decibel.
5, once mounting, freedom from repairs throughout one's life.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is Figure 1A-A directional profile figure.
Among the figure, the import of 1-muffler, 2-silencer casing, 3-muffler inner bag, 4-bracing or strutting arrangement, 5-silencing end.
The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details.
As shown in drawings, especially big air quantity chimney muffler of the present utility model, comprise muffler import 1 and silencer casing 2, muffler inner bag 3 is set in the silencer casing 2, the aperture of ￠ 3-5mm diameter is set on the muffler inner bag 3, muffler inner bag 3 links to each other with silencer casing 2 by the bracing or strutting arrangement 4 of muffler connecting plate, and silencer casing 2 is fixing with silencing end 5.
This silencer casing 2 is the cylindrical structural of ￠ 1000-28000mm diameter, silencer casing 2 links to each other with muffler import 1 by flange, muffler import 1 is for circular port and lead to muffler inner bag 3, muffler inner bag 3 is opening of import, the enclosed cylinder barrel in other end, silencing end 5 is welded to connect for cylindrical staving and silencer casing 2.
The utility model is that the noise when big air quantity source enters the original frequency that has changed sound in the noise reduction bucket by import, and makes sound disperse out by aperture on the noise reduction bucket, is discharged by the muffler gas outlet at last and enters atmosphere, reaches the noise reduction purpose.
