Abstract
The utility model discloses a double layer noise reduction and explosion proof device, which comprises an air inlet pipe connected with a baffle plate I by a short tube.A silencing means arranged between the baffle plate I and a baffle plate II is equipped with a plurality of noise reduction holes.The silencing means comprises an external-layer noise reduction board and an internal-layer noise reduction board.Both the external-layer noise reduction board and the internal-layer noise reduction board are cylindrical, which are matched with each other.When in use, the double layer noise reduction and explosion proof device is horizontally installed without vertical pipelines.The condensed water in the pipes can be automatically discharged to prevent the waterlogging.Meanwhile, the water flow impact and the crackle are avoided, thereby eliminating the danger of water flow bursting.In addition, the double layer noise reduction board is adopted instead of the conventional single layer noise reduction board, and the size and the density of noise reduction holes are rearranged, thereby improving the noise cancelling effect.The noise of discharging tail gas is reduced from 90 dB to 35 dB.
Description
Technical field
The utility model relates to the board-like noise reduction explosion-proof device of a kind of bilayer.
Background technique
Air compressor is widely used in industrial field as the pressure source of pneumatic equipment.The pressure gas of air compressor output is directly supplied with the user after generally all cooling through aftercooler; But all will carry out further drying process again to the gas of compressor output to the user that source of the gas is had relatively high expectations, the tail gas after the drying process is provided with silencing apparatus through outlet valve emptying at drain, to reduce exhaust sound.Present exhaust emissions silencing apparatus is vertical mounting type, and silencing apparatus is the single-layer type acoustical panel.In use there is the shortcoming of two aspects in the baffler of this kind form: the one, and the individual layer acoustical panel, erasure effect is poor, and 3 meters noises reach 90dB; The 2nd, overhead 4 meters in baffler, outlet pipe has one section horizontal segment, and this Duan Yiji condensed water is followed the impact and the cracker of current often during exhaust.
Summary of the invention
At above-mentioned prior art, the utility model provides a kind of tail gas that discharges safely and steadly, reduces the level of noise double-deck board-like noise reduction explosion-proof device is installed.
For achieving the above object, the utility model adopts following technological scheme:
The board-like noise reduction explosion-proof device of a kind of bilayer, it comprises suction tude, described suction tude is connected with silencer.
Described silencer comprises two cylindric acoustical panels that are nested, the two ends of acoustical panel are welded with baffle plate respectively, one of them baffle plate is connected with an end of short tube, flange I of the other end of short tube welding, and flange I is connected by the flange II that welds on bolt and the suction tude.
Described acoustical panel is provided with some bloops.
Principle of the present invention is as follows: the high temperature after drying is handled, high pressure, high humidity pressurized air tail gas enter secondary step-down body earlier after a dilatation step-down of internal layer acoustical panel in the utility model, arrange in atmosphere after the big volume dilatation of outer acoustical panel step-down forms low-pressure gas again.Will shift to high frequency or ultra-high frequency when the frequency spectrum of air-flow during, jet noise, the audible sound composition in the frequency spectrum obviously be reduced, thereby reduced interference and injury the people through small holes.
The beneficial effects of the utility model:
1, change former vertical mounting type into horizontal mounting type, cancelled vertical duct, the condensed water in the pipe can be discharged at any time voluntarily, has prevented ponding, has also just prevented the cracker of water impact and generation, has eliminated the danger of current explosions;
2, size, the density that former individual layer acoustical panel is changed into double-deck acoustical panel and bloop arranges again and arranges that strengthened erasure effect, the exhaust emissions noise reduces to 35dB by 90dB.
3, the utility model is static part entirely, need not adjust, and can come into operation after making, installing, and is simple and easy to do.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
As shown in Figure 1, the board-like noise reduction explosion-proof device of a kind of bilayer, it comprises suction tude 10, described suction tude 10 is connected with silencer; Described silencer comprises two cylindric acoustical panels that are nested, the two ends of acoustical panel are welded with baffle plate respectively, one of them baffle plate I is connected with an end of short tube 7, flange I 8 of the other end of short tube 7 welding, and flange I 8 is connected by the flange II 12 that welds on bolt 9 and the suction tude 10; Described acoustical panel is provided with some bloops.
Described acoustical panel comprises outer acoustical panel 1, and outer acoustical panel 1 matches with internal layer acoustical panel 3, and is cylindric.Outer acoustical panel 1 diameter is greater than internal layer acoustical panel 3 diameters (general scope), outer acoustical panel 1 has identical punching rate (3～5%) with internal layer acoustical panel 3, the slightly larger in diameter of internal layer bloop 4 is in the diameter of outer bloop 2. the internal and external layer acoustical panel, baffle plate I 6 and baffle plate II5 are steel plate, and adopt welded structure.
Dryer system is formed shown in Fig. 2 or 3, the pressurized air that water content is saturation state enters the A tower through suction valve 15, after the siccative adsorption treatment in the A tower, dew point drops to below-40 ℃, most of dry gas (more than 96) is supplied with through one-way valve I 16 input dry gas pipelines and is used, another part dry gas (below 4%) can enter heater heats by regeneration adjustable valve 19, resolve regeneration through the B tower dryer that 17 couples of one-way valve II adsorbed, tail gas is through outlet valve 18 emptying (drain is provided with baffler, to reduce exhaust sound).This process is the halftime, and the time is 60 minutes.The electric signal of sending by controller afterwards, transform exhaust passage then B tower adsorbs, and the A tower is resolved regeneration.Baffler is effective equipment that control aerodynamic force noise is propagated outward, can reduce exhaust sound.As shown in Figure 2, exhaust emissions noise reduction explosion-proof device is vertical mounting type, and silencing apparatus is a single-layer type noise reduction explosion-proof device 13.In use there is the shortcoming of two aspects in the baffler of this kind form: the one, and the individual layer acoustical panel, erasure effect is poor, and 3 meters noises reach 90dB; The 2nd, overhead 4 meters in baffler, outlet pipe has one section horizontal segment, and this Duan Yiji condensed water is followed the impact and the cracker of current often during exhaust.
