Abstract
The utility model discloses a silencer suitable for chemical plant relief valve, characterized by, include superimposed a plurality of layer of barrel in proper order, be provided with decibel tester in the middle of the barrel top of the superiors, every evenly be provided with a plurality of baffle on the barrel inner wall, the lower surface of baffle is provided with the drier, it is adjacent through screw thread swing joint between the barrel, the upper surface of the barrel of the superiors is provided with the catch basin. The utility model discloses the beneficial effect who reaches: the quantity of barrel can be adjusted according to the noise elimination sound effect of reality to this device, meets the requirements up to setting up the decibel that detects at the decibel tester of the superiors, the setting of baffle is used for upsetting sound wave and air current to the noise reduction, through the water direct reaction noise suppression effect in the catch basin of top surface, be convenient for go on adjusting fast to the number of barrel, adjust again rather than the postdetection through decibel tester.
Description
Technical field
The utility model relates to a kind of silencing apparatus being applicable to chemical plant safety valve, belongs to noise elimination equipment technical field.
Background technique
The silencing apparatus being applicable to chemical plant safety valve is a kind of silencing apparatus, be mainly used in electric power, chemical industry, safety valve in the industries such as metallurgy, effective noise elimination of the high temperature and high pressure steam discharge of Pcv valve and exhaust steam valve, for boiler safety door and exhaust steam valve, it can look at is a constituent element of pipeline, after Acoustic treatment is made in inside, generation and the propagation of noise can be weakened, outlet silencing noise amount is made to reach 20 ∽ 30 decibels (A sound level), correspondingly loudness reduces by more than 50%, subjective sensation has positive effect, silencing apparatus is the device of abatement pneumatic noise, installed in the duct or enter, on relief opening, while air-flow passes through, to noise, there is certain consumption.Existing silencing apparatus is because complex structure, weight are large, high temperature oxidation sound absorption filler, high velocity air impacts sound absorption filler, the reasons such as aqueous vapor infiltration sound absorption filler, silencing apparatus is easy to occur that maintenance is frequent, soundproof effect is poor, the situations such as life cycle is short, soundproof effect is poor, and intake and exhaust resistance is larger, air flow property is poor, greatly reduces the reliability of silencing apparatus work.
Model utility content
For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of structure simple, the silencing apparatus of what durability degree was high be applicable to chemical plant safety valve.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
Be applicable to a silencing apparatus for chemical plant safety valve, it is characterized in that, comprise the some layers of cylindrical shell superposed successively; The cylindrical shell crown center of the described the superiors is provided with a decibel testing instrument; Each described cylinder inboard wall is evenly provided with several dividing plates; The lower surface of described dividing plate is provided with siccative; Be flexibly connected by screw thread between adjacent described cylindrical shell; The upper surface of the cylindrical shell of the described the superiors is provided with water storage tank.
The aforesaid silencing apparatus being applicable to chemical plant safety valve, is characterized in that, the dividing plate of adjacent described cylindrical shell is interspersed.
The aforesaid silencing apparatus being applicable to chemical plant safety valve, is characterized in that, the sound absorption inwall of described cylindrical shell being provided with uneven distribution is cotton.
The aforesaid silencing apparatus being applicable to chemical plant safety valve, is characterized in that, described dividing plate is provided with equally distributed small sircle hole.
The aforesaid silencing apparatus being applicable to chemical plant safety valve, is characterized in that, the middle part of described undermost cylindrical shell is provided with suction port.
The aforesaid silencing apparatus being applicable to chemical plant safety valve, is characterized in that, described undermost cylindrical shell bottom is provided with rubber sheet gasket.
The beneficial effect that the utility model reaches: this device can regulate the quantity of cylindrical shell according to the noise elimination sound effect of reality, until the decibel that the decibel testing instrument being arranged on the superiors detects meets the requirements; The setting of dividing plate is used for upsetting sound wave and air-flow, thus reduces noise; Directly react soundproof effect by the water in the water storage tank of end face, be convenient to adjust rapidly the number of cylindrical shell, instead of by adjusting again after the detection of decibel testing instrument.
Accompanying drawing explanation
Fig. 1 is the structural representation of this device.
The implication of reference character in figure:
1-cylindrical shell, 2-decibel testing instrument, 3-water storage tank, 4-dividing plate, 5-suction port, 6-rubber sheet gasket.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
As shown in Figure 1, this device is collected in cylindrical shell 1 by the gentle suction port 5 that flows through of noise sent by equipment relief opening, reduces widely after the effect of the small sircle hole of noise on dividing plate 4 and dividing plate 4.When specifically using, substantially reflecting soundproof effect according to the fluctuation of water in water storage tank 3, being tested by decibel testing instrument 2 afterwards, if still defective, then increasing the number of cylindrical shell 1, until the position that meets the requirements.Owing to being threaded connection between cylindrical shell 1, therefore increase and decrease get up very convenient, simple to operate.
The rubber sheet gasket 6 that cylindrical shell 1 bottom is arranged is for fixed cylinder 1, and the frictional force of rubber sheet gasket 6 is comparatively large, and has certain deformation, can fill up gap, thus ensure the erasure effect of self.
During practical operation, because how many safety door or exhaust steam valves have water vapour out, make moist after dividing plate 4 Long-Time Service thus reduce soundproof effect, the lower surface of dividing plate 4 is provided with siccative.The sound absorption of the uneven distribution that the inwall of cylindrical shell 1 is arranged is cotton, can improve erasure effect further.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the utility model know-why; can also make some improvement and distortion, these improve and distortion also should be considered as protection domain of the present utility model.
