Abstract
The utility model relates to a feeding-type gas muffler which is mainly composed of a metal inner sleeve pipe, a metal outer sleeve pipe, granular materials and end covers. The utility model has the characteristics of high strength, simple manufacturing process, low cost and convenient replacement, which has a wide material source and is suitable to eliminate noise produced by exhausting compressed air by pressure and heating liquid by vapor. The feeding-type gas muffler can be used singly or in series.
Description
The utility model relates to a kind of material filling type gas silencing apparatus.
At present, the micropore sintered formula silencing apparatus of use, cost height, manufacturing process difficulty are greatly, the stoneware pipe surface micropore is easily blocked, working life short.
The utility model is exactly in order to overcome above-mentioned deficiency, designs a kind of material filling type gas silencing apparatus of more effectively eliminating noise.
The utility model is achieved in that the inner metal sleeve pipe that a metal jacket pipe that is installed with porous and intermediate section are installed with porous at one end welds, the other end is connected to end cap, between two sleeve pipes, be filled with granular material, its state of rest can be regulated with end cap, in order to prevent irregular leakage, fill with particle layer between end cap and inner sleeve, see shown in the accompanying drawing 1.When gas passes the inner sleeve aperture and enters the countless micropore that granular material forms, because its tortuous passageway has consumed the kinetic energy of gas, gas has been divided into fine a fluid stream, thereby has reduced the impact to medium, make turbulent noise drop to floor level, played the effect of eliminating noise.
This kind material filling type gas silencing apparatus, have the compressive strength height, can be acidproof, alkaline-resisting, the technology manufacturing is simple, cost is low, replacing is convenient, applied widely and packing material employing building stones or metal species, advantages such as its source is wide, according to different needs, can select for use different materials, different size of grain to adapt to, during practical application, can use by one or more series connection.
A specific embodiment below in conjunction with accompanying drawing narration material filling type gas silencing apparatus.
The longitudinal sectional drawing of Fig. 1, material filling type gas silencing apparatus.
1---outer sleeve 2---inner sleeve 3---end cap 4---particle layer 5---granular material.
Inner sleeve (2) is according to different air demands, adopt the stainless steel pipe of the caliber different sizes such as ", 6 " that is respectively 4,250 of the apertures of processing φ 3mm on tube wall, outer sleeve (1) is formed by stainless steel turning or with the commercially available Stainless Steel Tube material of φ 65mm, 500 of the apertures of same processing φ 3mm on the tube wall, then inner sleeve (2) is packed into wherein, (δ=3mm) locate by welding with end cap (3) for one end, the irregular geometric form granular material (5) that with particle diameter is 3～5mm is again inserted between two sleeve pipes, and filling density is 36g/cm
3, weld the other end sealing at last, because the vent sectional area of 500 φ 3mm on the outer sleeve (1) is 35.5cm
2Be 5 times of the steam pipe sectional area, resistance is very little.
The noise that this kind material filling type gas silencing apparatus produces when being fit to eliminate discharge of pressure pressurized air or steam heated liquid, dyed pot test shows that acoustical absorptivity is 100%.
The adhesion test condition:
Vapor tension 4kg/cm
2, container volume 2 * 0.6 * 0.5m
Heat medium: water volume is 0.4m
3
The original noise of experimental enviroment: 64dB(A) (boiler room influence)
The noise figure that 20 ℃ of water temperatures (heating)/(12 minutes) are 90 °
When not installing this silencing apparatus work additional: 76dB(A)～85dB(A)
When having installed this silencing apparatus work additional: 64dB(A) (basic noiseless produces)
Claims (2)
1, a kind of material filling type gas silencing apparatus, inner sleeve (2), outer sleeve (1) that the porous of being installed with is arranged, two sleeve pipes at one end weld, and it is characterized in that being filled with between two sleeve pipes granular material (5), and the other end of two sleeve pipes is connected to the end cap (3) of the state of rest of can regulate granular material (5).
2, end cap according to claim 1 (3) is characterized in that being filled with particle layer (4) between end cap (3) and inner sleeve (2).
