Abstract
The utility model relates to a large-hole reduction voltage dissipative muffler. The utility model comprises a muffling barrel and a flow controlling (equal) pipe. Holes whose bore diameters are D[1] (10 mm < D[1]< = 25 mm) are distributed in the wall of the muffling barrel. The holes whose bore diameters are D[2] (7 mm < D[2]< = 25 mm) are distributed in the wall of the flow controlling (equal) pipe of the muffling barrel. By utilizing the large-holes for the voltage reduction and the noise elimination, the utility model has the advantages of big noise eliminating quantity, light weight, safe operation, simple manufacture and simple installation.
Description
The utility model relates to a kind of macropore step-down silencing apparatus that is used for the silencing apparatus, particularly a kind of full steel structure of exhaust (vapour) noise reductions such as boiler, pressurized container.。
At present, a kind of micropole diffusor is arranged, distributed aperture is the aperture of 1-3mm on its noise elimination barrel, its noise-cancelling theory is to utilize the discharging of air communication small holes, the noise peak frequency is risen to more than the 20000Hz by 1000-2000Hz, the sentient acoustic energy of people's ear is reduced significantly, thereby reach the noise reduction purpose.The pressure that bears in the micropole diffusor work still belongs to the pressurized container scope, manufacturing technology is had relatively high expectations, requirement to material is also higher, increased manufacture difficulty, simultaneously, there is the easily stifled shortcoming of aperture in micropole diffusor, may cause because of the unusual rising of internal pressure explosion, even cause more serious consequence, so its Security is not enough.
The purpose of this utility model is, overcomes the deficiency of micropole diffusor, provides a kind of and is convenient to make, safe and reliable macropore step-down silencing apparatus.
Composition of the present utility model comprises the level of eliminating the noise, and---silencing pot and control (all) stream level---controls (all) stream pipe, the silencing pot upper and lower end has end socket, control (all) stream Guan Yiduan is connected with the pipeline of fed sheet of a media, one end stretches in the silencing pot, and fixedly connected with the silencing pot lower end, it is characterized in that distributed aperture is D on the noise elimination barrel
1The hole, 10mm＜D
1≤ 25mm, distributed aperture is D on the control in silencing pot (all) the stream tube wall
2The hole, 7mm＜D
2≤ 25mm.The utility model utilizes double-deck macropore step-down to eliminate the noise, different with the noise-cancelling theory of micropole diffusor, owing to adopt macroporous structure, can make the medium air-flow rapid depressurization of discharging, obtain big sound deadening capacity, also make simultaneously in the silencing apparatus working pressure reduce to minute-pressure, thereby make the macropore step-down silencing apparatus can be not according to the standard manufacture of pressurized container, reduce manufacture difficulty and to the requirement of material, the corresponding minimizing of cost.On the other hand, adopt the macropore step-down to eliminate the noise, overcome the easily stifled shortcoming of aperture, guaranteed the safety reliability of silencing apparatus, allow to contain solid shape impurity and corrosive gas in the discharge medium, enlarged the use occasion of silencing apparatus.
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.
Fig. 1 is the utility model structural representation.
As shown in Figure 1, the composition of the utility model macropore step-down silencing apparatus comprises silencing pot 2 and current-sharing pipe 1, the silencing pot upper and lower end has end socket (not drawing among the figure), current-sharing pipe 1 one ends are connected with the pipeline (not drawing among the figure) of fed sheet of a media, one end stretches in the silencing pot 2 and with the silencing pot lower end fixedlys connected, and distributed aperture is D on silencing pot 2 walls
1Hole 4,10mm＜D
1≤ 25mm, distributed aperture is D on current-sharing pipe 1 wall in silencing pot
2Hole 3,7mm＜D
2≤ 25mm, the distribution in hole can be certain geometric figure, for example rhombus, rectangle etc.The quantity in internal and external layer hole is according to the sound deadening capacity decision of design, and total effective cross section in hole should be greater than total effective cross section of control (all) stream Guan Shangkong on the silencing pot, and the two all should be when designing discharge capacity desired total effective cross section.In order to guarantee the structural strength of macropore step-down silencing apparatus, all should there be certain lay ratio (ratio of adjacent two hole centre distance and bore dia) in inside and outside layer hole, and the lay ratio in the hole on hole on the utility model silencing pot and control (all) the stream pipe all is 1.5-10.0.Among the embodiment, it is that quality carbon steel, the alloy steel or stainless steel of 0.5mm-30mm manufactured that silencing pot and control (all) stream pipe can be selected thickness for use.One ton of medium of every discharging, one decibel of noise of reduction, the utility model consumes metallic material and is lower than 0.07 kilogram, and micropole diffusor is the 0.07-0.1 kilogram, the noise elimination effect under equal conditions surpasses micropole diffusor 5-7 decibel, simultaneously, because the utility model silencing apparatus does not have the discharging reaction force in running, so simple installation, can not need specific bearing, directly by the media discharge piping support that is connected with silencing apparatus, maintenance, maintenance workload is very little, and the layout of silencing apparatus can adopt multiple modes such as level, vertical even inclination.The utility model is particluarly suitable for superhigh temperature (600 ℃), overcritical (30Mpa) and following each class parameter state and uses down.
