Abstract
The utility model relates to a muffler with a plurality of coaxial perforated pipes, which is mainly used for muffling of air and corrosive gas in the chemical industry. The muffler comprises perforated pipes (1) and an outer sleeve (4), and is characterized in that the perforated pipes (1) are multiple in numbers, and pluralities of the perforated pipes (1) are coaxially arranged inside the outer sleeve (4). In the plurality of perforated pipes, a perforated pipe arranged in the middle of the outer sleeve (4) is a middle perforated pipe (1.1), the others are peripheral perforated pipes (1.2), an air inlet end of the middle perforated pipe (1.1) is a front end opened and the other end is a rear end enclosed, both ends of the peripheral perforated pipes (1.2) are enclosed, and the front end of the outer sleeve (4) is enclosed and the rear end is open. The muffler of the utility model can increase the muffling area on the premise of guaranteeing the original overall dimension of the muffler.
Description
Technical field
The utility model relates to a kind of silencing apparatus, is mainly used in the noise elimination of chemical industry air, corrosive gas.
Background technique
Before the utility model was made, the silencing apparatus that is used for chemical industry air, corrosive gas at present mainly was made up of perforation center tube, outer cylinder body and filler etc.Such silencing apparatus has only a perforation center tube to play the noise elimination effect, and the noise elimination area is little, and noise elimination speed is fast, the noise elimination weak effect.For reaching the noise elimination requirement of user expection, common way is that the length by lengthening perforation center tube strengthens the noise elimination area.The length of silencing apparatus but this way has extended again greatly, this has brought trouble again for installation of user, and also be not suitable for the extending use of silencing apparatus of some installation site.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of silencing apparatus with a plurality of coaxial perforated pipes that can strengthen the noise elimination area under the prerequisite that guarantees the original boundary dimension of silencing apparatus is provided.
The purpose of this utility model is achieved in that a kind of silencing apparatus with a plurality of coaxial perforated pipes, comprises perforated pipe and outer sleeve, it is characterized in that:
Described perforated pipe has a plurality of, and a plurality of perforated pipes are coaxial to be arranged in the outer sleeve,
In described a plurality of perforated pipe, place a perforated pipe at outer sleeve center to be referred to as the central hole pipe, all the other perforated pipes then are referred to as peripheral perforated pipe,
Described central hole pipe inlet end is that front end is uncovered, and the other end is a back-end closure, described peripheral perforated pipe closed at both ends, described outer sleeve front end sealing, rear end opening.
Working principle:
Air or corrosive gas are entered by the central hole pipe front end of perforated pipe, after a plurality of perforated pipe multi-stage speed-reducings are eliminated the noise, are gone out by the outer sleeve rear end at last.
Because the utility model has adopted a plurality of perforated pipes, under the prerequisite that guarantees the original boundary dimension of silencing apparatus, can increase the noise elimination area of silencing apparatus greatly like this, reduce the source of the gas movement velocity, it is effective therefore to eliminate the noise.
Description of drawings
Fig. 1 is the vertical section structure schematic representation that the utlity model has the silencing apparatus of a plurality of coaxial perforated pipes.
Among the figure: perforated pipe 1, outer sleeve 2, supporting frame I 3, supporting frame II 4, central hole pipe 1.1, peripheral perforated pipe 1.2.
Embodiment
Referring to Fig. 1, the silencing apparatus with a plurality of coaxial perforated pipes that the utility model relates to mainly is made up of perforated pipe 1 and outer sleeve 2.
Described perforated pipe 1 has a plurality of, and a plurality of perforated pipe 1 coaxial being arranged in the outer sleeve 2 are supported with supporting frame I 3 between the adjacent perforated pipe 1, supports with supporting frame II 4 between perforated pipe 1 and the adjacent outer sleeve 2.
In a plurality of perforated pipes 1, place a perforated pipe at outer sleeve 2 centers to be referred to as central hole pipe 1.1, all the other perforated pipes then are referred to as peripheral perforated pipe 1.2.
Described central hole pipe 1.1 inlet ends are that front end is uncovered, and the other end is a back-end closure, described peripheral perforated pipe 1.2 closed at both ends, described outer sleeve 2 front ends sealing, rear end opening.
Claims (2)
1, a kind of silencing apparatus with a plurality of coaxial perforated pipes comprises perforated pipe (1) and outer sleeve (2), it is characterized in that:
Described perforated pipe (1) has a plurality of, and a plurality of perforated pipes (1) are coaxial to be arranged in the outer sleeve (2),
In described a plurality of perforated pipe (1), place a perforated pipe at outer sleeve (2) center to be referred to as central hole pipe (1.1), all the other perforated pipes then are referred to as peripheral perforated pipe (1.2),
Described central hole pipe (1.1) inlet end is that front end is uncovered, and the other end is a back-end closure, described peripheral perforated pipe (1.2) closed at both ends, the sealing of described outer sleeve (2) front end, rear end opening.
2, a kind of silencing apparatus with a plurality of coaxial perforated pipes according to claim 1 is characterized in that: support with supporting frame I (3) between the adjacent perforated pipe (1), support with supporting frame II (4) between perforated pipe (1) and the adjacent outer sleeve (2).
