Abstract
The utility model belongs to the technical field of acoustics, which relates to a silencing device for an air stream system containing acid, alkali and a large amount of moisture content. The silencing device is composed of an outer box body, a metal perforated pipe and a perforated sound absorbing material with high hydrophobicity. The bottom part of the silencing device is provided with a drainage baffle plate, a water collecting chamber, a drainage pipe, etc. The utility model can be combined by a plurality of silencing devices according to the sizes of system air volume. The utility model has the advantages of wide silencing frequency band, good aerodynamic quality, large silencing quantity, small size, simple structure, wide range of application of air volume, etc. The utility model can be widely used for the silencing to an air stream system containing acid, alkali and a large amount of moisture content.
Description
The utility model belongs to the acoustic technique field, relates to a kind of acid, alkali, air flow system wet type silencing equipment that water content is big of containing.
Present domestic silencing apparatus is of a great variety, but according to actual requirement of engineering, for containing the silencing equipment of acid, alkali, air flow system that water content is big, all has noise elimination frequency band narrow, bulky, and complex structure is invested high deficiency.
The purpose of this utility model is to provide a kind of wet type silencing apparatus, and anechoic frequency bandwidth is simple in structure, can be widely used in the noise elimination that contains acid, alkali, air flow system that water content is big.
The utility model is achieved in that modular silencing apparatus is made up of external box of microvave, metal piercing pipe, sound-absorbing porous material that hydrophobicity is high, in the silencing apparatus bottom draining dividing plate, collecting chamber, waste pipe etc. is installed.According to the systematic air flow size, silencing apparatus can a plurality ofly make up.
The utlity model has anechoic frequency bandwidth, good aerodynamic quality, sound deadening capacity is big, and volume is little, and is simple in structure, is suitable for advantages such as the air quantity scope is wide.
Below in conjunction with accompanying drawing the utility model is elaborated:
Fig. 1 is a front elevation view of the present utility model.
Fig. 2 is a side elevational view of the present utility model.
Part 1 is the silencing apparatus external box of microvave among the figure, and part 2 is end plates, and part 3 is rectangular metal perforated pipes, part 4 is the high sound-absorbing porous materials of hydrophobicity, part 5 is draining dividing plates, and part 6 is collecting chambers, and part 7 is water conservancy diversion reducer pipes, part 8 is supports, part 9 is waste pipes, and part 10 is control valves, and part 11 is weep holes, part 12 is soil cleaning ports, and part 13 is masks.
Contain the big strong noise air-flow of acid, alkali, water content when silencing apparatus rectangular metal perforated pipe 3, because the resistance of wall perforation place and the transmission of sound-absorbing porous material 4, absorption portion acoustic energy, when through the airspeed of silencing apparatus rectangular metal perforated pipe 3＜15m/s, the noise elimination value is 25-30db, resistance is 100-150pa, thereby noisiness is reduced, and reaches the noise elimination purpose.When acoustic energy is absorbed transmission, part water smoke is adsorbed by sound-absorbing material 4 in the air-flow, form droplet and be deposited on the silencing apparatus bottom discharge dividing plate 5, flow into collecting chamber 6 through weep hole 11, timing is opened control valve 10 water is discharged through waste pipe 9, thereby has guaranteed the physical property of sound-absorbing material 4.
Present embodiment is that two groups of modular silencing apparatuss combine up and down.According to the size of air flow system air quantity, more silencing apparatus can be organized and combine.
Material of the present utility model adopts carbon steel, stainless steel or glass fibre reinforced plastics, the metal piercing pipe except that rectangle, also available circle, other shape such as square, punching rate＞20%.Sound-absorbing material 4 is the super glass wool of hydrophobicity＞98.5%, porosity ratio 90%.
Claims (3)
1 one kinds of wet type silencing apparatuss of forming by external box of microvave (1), metal piercing pipe (3), sound-absorbing porous material (4) that hydrophobicity is high, it is characterized in that communicating at the draining dividing plate (5) of silencing apparatus bottom mounting strap weep hole (11) and with collecting chamber (6), the water of condensation of collecting chamber (6) regularly effluxes the sound-absorbing porous material (4) that the filling hydrophobicity is high between rectangular metal perforated pipe (3) through control valve (10).
2 wet type silencing apparatuss according to claim 1, the outside that it is characterized in that rectangular metal perforated pipe (3) wrap up in through the glass fiber cloth of silicidation as mask (13).
3 wet type silencing apparatuss according to claim 1, the cross section that it is characterized in that the metal piercing pipe is for circular or square, and punching rate is greater than 20%.
