Abstract
The utility model relates to the technical fields of noise silencing equipment, in particular to a chimney silencer, which comprises a cylindrical outer casing and an inner container, wherein the inner container is positioned in the cylindrical outer casing, and is connected with the cylindrical outer casing through a bracket, the inner container is provided with silencing holes, silencing sponges are filled between the inner container and the cylindrical outer casing, the two ends of the inner container are respectively provided with an inserting opening and a stop opening, and the two ends of the cylindrical outer casing are respectively provided with a flange. The chimney silencer has the advantages that the structure is simple; by arranging the inner container and the silencing sponges, noise generated by the chimney is greatly reduced; by arranging the inserting opening and the stop opening, the size of the silencer is smaller, and the transportation and installation are convenient; by welding a steel plate at the exterior of the cylindrical outer casing, vacuumizing is performed between the steel plate and the cylindrical outer casing, so the noise can be further reduced.
Description
Technical field
The utility model relates to noise silencing equipment technical field, relates in particular to a kind of chimney muffler.
Background technology
Due to coking industry, thermal power industry, large-sized boiler, the import and export air quantity of capacity coke oven cleaning shaft and chimney is large, reach 18-45 ten thousand m3/h, the noise that blower fan produces is also large especially, particularly concerning accommodation people around, have the greatest impact evening, around general boiler, the noise equivalent sound level of position of meters away is all more than 65 decibels, considerably beyond people to the standard of standing of noise (by the regulation of environmental protection, must not exceed 60 decibels daytime, night not exceed 50 decibels), the muffling device that general blower fan is joined can not meet noise noise reduction requirement, how to abate the noise and become people's consideration long-term indeterminable problem.
Utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and a kind of chimney muffler is provided, and reduces the noise that chimney produces, and is convenient to transportation and installs.
The utility model for achieving the above object, by the following technical solutions:
A kind of chimney muffler, it is characterized in that: comprise cylinder blanket and be positioned at the inner bag of described cylinder blanket inside, described inner bag is connected by support with described cylinder blanket, described inner bag is provided with bloop, between described inner bag and described cylinder blanket, be filled with silencing cotton, the two ends of described inner bag are respectively equipped with socket and seam, and the two ends of described cylinder blanket are respectively equipped with ring flange.
The outside of described cylinder blanket is provided with vacuum layer.
Described socket and seam are provided with spongy layer.
The beneficial effects of the utility model are: the utility model is simple in structure, by inner bag and silencing cotton are set, greatly reduce the noise that chimney produces, the setting of socket and seam can make this muffler be arranged to less mentioning so that transport and install, at cylinder blanket outside welding one deck steel plate, steel plate and cylinder blanket vacuumize, and noise further can be reduced like this.
Accompanying drawing explanation
Fig. 1 is the utility model monomer structure schematic diagram;
Fig. 2 is the utility model package assembly schematic diagram;
In figure: 1, cylinder blanket; 2, inner bag; 3, bloop; 4, silencing cotton; 5, socket; 6, seam; 7, ring flange; 8, vacuum layer; 9, spongy layer.
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in Figure 1, a kind of chimney muffler, comprise cylinder blanket 1 and be positioned at the inner bag 2 of described cylinder blanket inside, described inner bag is connected by support with described cylinder blanket, described inner bag is provided with bloop 3, between described inner bag and described cylinder blanket, be filled with silencing cotton 4, the setting of silencing cotton can reach 0.94 by sound-absorption coefficient within the scope of 125-4000HZ noise.For the ease of transportation and installation, the two ends of described inner bag are respectively equipped with socket 5 and seam 6, and the two ends of described cylinder blanket are respectively equipped with ring flange 7.When mounted, the socket of First muffler inserts in the seam of second muffler, increases according to this length of muffler.In order further to reach better erasure effect, the outside of described cylinder blanket is provided with vacuum layer 8.In order to prevent producing and leak sound two muffler junctions, described socket and seam are provided with 9, two spongy layer docking of spongy layer, have reached the complete seal of muffler.
The utility model is simple in structure, by inner bag and silencing cotton are set, greatly reduce the noise that chimney produces, the setting of socket and seam can make this muffler be arranged to less mentioning so that transport and install, at cylinder blanket outside welding one deck steel plate, steel plate and cylinder blanket vacuumize, and noise further can be reduced like this.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
