Abstract
The utility model relates to a high-pressure exhausting silencer belonging to a silencing device, which comprises a silencer body, wherein a silencing device in the silencer body adopts a double-layer micro perforated panel structure, the silencer body is arranged in an oil-proof sheath, the oil-proof sheath is connected with an oil-proof sheath supporting plate, and a pollutant discharging outlet is arranged on the oil-proof sheath supporting plate. The silencer is characterized in that the oil-proof sheath is added on the silencer body for preventing oil content from entering a pipeline of a device from the position of the silencer, and effectively prevents the silencer body from pollution, the silencing device in the silencer body adopts the double-layer micro perforated panel structure, which guarantees the silencing effect of a wide band, and the path during designing is bigger, thereby enabling air flows to slowly discharge, and prevents air from vibration, thereby realizing the aim of good silencing. The high-pressure exhausting silencer provided by the utility model has reasonable design, simple structure, convenient manufacturing and rapid installation, and can solve the problem of emptying silencing of high-pressure and high flow rate air, and also can prevent pollution to the integral device from external environment, and prolongs the service life of the silencer.
Description
Technical field
The utility model relates to a kind of exhaust noise silencing equipment, particularly a kind of high pressure silencer that is applicable to oil field oil drilling supercharging equipment mesohigh gas exhaust emptying.
Background technique
The influence of noise on human and harm are a lot, and noise pollution has become the problem of contemporary world.Suppressing noise from sound source, is the essential measure of control noise.Therefore, generally take now to insulate against sound, absorb sound, the noise in the technology control propagation path such as noise elimination.
Now the baffler on the market is divided into following severally, and a kind of be resistive baffler, and it is a kind of absorption silencer, when utilizing sound wave to propagate in porous sound-absorbing material, because of rubbing acoustic energy is converted into heat energy and dissipates, thereby reach the purpose of noise elimination.Resistive baffler has good medium-high frequency acoustic attenuation performance, and is relatively poor to the low frequency acoustic attenuation performance but in general.A kind of is reactive muffler, it does not use sound-absorbing material, but rely on the sudden change of pipeline section or otherly connect that resonant cavity etc. causes the change of impedance in the propagation of sound process and the reflection, interference and the resonance sound-absorbing that produce acoustic energy reduces silencing apparatus to extraradial acoustic energy, reach the noise elimination purpose.From energy point of view, dissipative muffler adopts is that the method for transformation of energy (converting acoustic energy to heat energy by acting) reduces the acoustic energy in silencing apparatus outlet port, and the method that reactive muffler mainly utilizes acoustic energy to shift reduces the acoustic energy in silencing apparatus outlet port.Also has a kind of exhaust emptying silencing apparatus that is.High pressure gas is a kind of jet flow. this stream pressure height, flow is big, exhaust emptying noise is produced by the unstability that high velocity air flows, airflow flowing generally has the characteristics of high temperature, high pressure, high flow rate, it is the important noise source in the industrial production such as chemical industry, oil, electric power, metallurgy, the noise of its discharging has the advantages that intensity is big, frequency spectrum is wide and the influence of noise scope is big, and the very strong health hazard to people of this noise is very big.The principal mode of exhaust emptying silencing apparatus has micropore jet silencing apparatus, porous diffusor, expenditure and pressure silencing apparatus etc.
Baffler during now design is used general only merely the noise when eliminating exhaust emptying do, can not adapt in the varying environment fully.
Summary of the invention
The purpose of this utility model provides convenient, the big latus rectum of a kind of loading, big discharge capacity, simple in structure, and is light, can be in air uses in the oil field mine of many, the poor working environment of oil molecule, has the high pressure gas baffler of oil-resistant function.
The purpose of this utility model is achieved in that a kind of high pressure gas baffler, comprise the baffler body, the intrinsic muffling device of baffler adopts double-deck microperforated panel structure, and the baffler body places in the oil shield, oil shield is connected with the oil shield support plate, and the oil shield support plate is provided with sewage draining exit.
The high pressure gas baffler that the utility model provides has installed oil shield additional outside the baffler body, stop oil content to enter into the pipeline of equipment from the baffler position, has effectively avoided the baffler body to be polluted; Muffling device adopts microperforated panel to eliminate the noise in the baffler body, and that the micropunch plate muffler of its Structural Hardware has is high temperature resistant, damp proof, fire prevention, characteristic such as anticorrosion, and is adapted at use high-voltage high-speed airflow under.Because of the noise of exhaust emptying has broadband properties, existing low frequency is given birth to ripple.The medium-high frequency sound wave is arranged again, and the gas pressure height of this baffler institute emptying of process, therefore when design, adopt double-deck microperforated panel structure, guarantee wide band noise elimination effect, and latus rectum is bigger during design, thereby air-flow is slowly emitted, avoid air vibration, thereby reach the purpose of good noise reduction.High pressure gas baffler provided by the utility model is reasonable in design, simple in structure, easy to make, quick for installation, can solve the problem of high pressure, big discharge capacity gas emptying noise reduction, can avoid external environment again, prolong the working life of baffler the pollution that integral device caused.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present utility model.
Embodiment
As shown in Figure 1, the utility model comprises baffler body 1, and the muffling device in the baffler body 1 adopts double-deck microperforated panel structure, and baffler body 1 places in the oil shield 2, and oil shield 2 is connected with oil shield support plate 3, and oil shield support plate 3 is provided with sewage draining exit 4.
When the utility model was installed: the welding height-diameter flange was connected with pipeline bolt in the complete equipment in the baffler body 1; The outer wire bond of welding is connected on the reserved location of oil shield support plate 3, becomes sewage draining exit 4; Oil shield support plate 3 is welded on the baffler body 1, oil shield 2 is connected with oil shield support plate 3 usefulness bolts.Weld seamless steel pipe 5 and welded flange 6 welding, be welded on another stomidium of oil shield 2 then, the welding complete equipment is connected to the pipeline of prying body on the last welded flange 6, and the gaseous emission that makes the process noise reduction is in the external world.
