Field of the Invention The present invention relates to a muffler and a muffler for manufacturing a muffler, and more particularly, to a muffler and a muffler for muffling a muffler having a means for remarkably attenuating low-frequency noise generated from a muffler.

The tower is a facility for the discharge of gas or water vapor on the upper part of facilities requiring the discharge of gas or water vapor. The silencer of the tower is designed to reduce the noise generated by discharge of high pressure steam or gas from the tower. It is an exit structure that is connected to the upper end of the tower.

 Noises may be transmitted to the distant place from the muffler itself. In this case, the noise generated is caused by the vibration of the silencer and the noise generated by the fluid passing through the silencer. Particularly, the noise propagated far away from the silencer is a low-frequency noise due to vibration of the silencer itself, and conventionally, there is no means for attenuating such low-frequency noise.

A related art for solving such a problem is a 'silencer for a gas shield tower' disclosed in Patent Registration No. 10-0962523 (registered on June 06, 2010) shown in FIG. 1.

Especially, it is necessary to develop a technique to attenuate low frequency noise in the low-frequency noise, which causes damage to the air due to propagation far away.

Therefore, there is a need for a silencer technology which is simple in structure and has a means for remarkably attenuating noise generated in a conventional silencer for a defense tower at a low cost.

The specific structure or functional description presented in the embodiment of the present invention is merely illustrative for the purpose of illustrating an embodiment according to the concept of the present invention, and embodiments according to the concept of the present invention can be implemented in various forms. And should not be construed as limited to the embodiments described herein, but should be understood to include all modifications, equivalents, and alternatives falling within the spirit and scope of the invention.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

First, a description will be given of a muffle tower according to the present invention. Next, a method of manufacturing a muffler will be described.

Before explaining the present invention in detail, the entire structure of the diffusion tower will be briefly described.

The KOGAS Supply Management Station is responsible for lowering the gas sent to the high pressure from the natural gas production base through the underground piping to a certain pressure, measuring the amount of the supplied gas and supplying it to the city gas company or the power plant. Generally, the diameter of the underground pipe is from 0.762m to 0.508m, and the gas pressure through the pipe is from a maximum of 6.86MPa to a minimum of 0.83MPa. A supply tower is installed in the supply station in order to discharge the gas in the pipe quickly after shutdown by the shutoff valve in case of maintenance of the buried piping and emergency occurrence.

The height of the defense tower is 25m, 40m as standard, and is installed at a sufficient height so that the landing concentration of released gas is below the lower limit of explosion. A silencer is installed at the top or bottom of the tower to reduce the noise generated when the high pressure gas is discharged through the tower to the atmosphere.

Since the silencer generates high noise when the piping pressure is over 3 MPa, the cause of the noise can be found by carrying out fluid - structure ductility analysis. As a result of the ductility analysis, it is confirmed that the upper silencer mixes the structural noise generated by the fluid with the structure due to the high pressure gas discharge and the fluid noise generated by the fluid flow. In the case of the lower type, it is confirmed that the noise is divided into the flow noise at the end of the bulb top and the structural noise at the bottom through the silencer.

The muffler according to the present invention is an upper muffler, and the overall view of the muffler is similar to that of the prior art shown in Fig.

12, a vent pipe 1 connected to the gas supply station is vertically bent and extends vertically upward. The outer circumferential surface of the vent pipe 1 is surrounded by a protective pipe 8, And a drain pipe 5 is installed inside the protective pipe 8. [ The auxiliary frame 2 may be installed outside the protective pipe 8 as shown in FIG. The condensed water generated during discharge of the gas through the gas discharge hole 11 in the diffuser 10 to be described later is drained through the drain pipe 5 without flowing into the diffuser 10.

However, the silencer shown in Fig. 12 is not one of the silencers of the present invention and is one of the prior arts.

Hereinafter, the present invention will be described in detail.

The muffler according to the present invention comprises a diffuser 10, an inlet cell, an enclosure 30, and a horizontal reinforcement as shown in FIG.

The diffuser 10 is a cylinder communicating with the vent pipe 1, and a gas discharge hole is formed on the outer circumferential surface thereof. The gas discharge hole 11 acts to primarily attenuate the pressure and the noise when the gas is discharged into the gas discharge hole 11. At this time, the discharged gas is raised to the atmosphere.

The inlet cell 20 is a cylindrical body that surrounds the outer circumferential surface of the diffuser 10, as shown in Fig. The inlet cell 20 extends higher than the upper end of the diffuser 10 and widens toward the upper side. At the upper end of the inlet cell (20), an excellent cover (31) formed of a convex curved surface is disposed so that rainwater can not flow into the inlet cell.

The lower portion of the enclosure 30 extends to the upper end of the protective pipe 8 and is inclined so as to have a narrower lowered shape toward the upper portion and is formed to surround the outer peripheral surface of the inlet cell.

The horizontal reinforcement 40 is made up of a reinforced donut plate 41. At this time, the reinforced donut plate 41 is preferably arranged so that a plurality of layers are formed as shown in FIG. 2 and FIG.

The reinforced donut plate 41 is provided as a hollow plate in which the enclosure 30 is inserted into the hollow of the reinforced donut plate 41. The reinforced donut plate 41 may be attached to the outer peripheral surface of the enclosure 30 in various ways as a rigid rigid material.

As shown in FIG. 4, the reinforcing dovetail plate 41 may be installed on the outer circumferential surface of the enclosure 30 in the form of heat shrinking. That is, the reinforced donut plate 41 may be installed by inserting the enclosure 30 into the hollow of the reinforced donut plate 41 while heating the reinforced donut plate 41 at about 250 to 600 degrees Celsius. In this case, by using the point that the diameter of the horizontal cross-sectional area becomes larger as the enclosure 30 moves from the lower part to the upper part, the reinforcing dovetail plate 41 to be disposed on the upper part in order from the reinforcing dovetail plate 41 41) in this order.

At this time, in the state where the reinforcing dovetail plate 41 is fitted in the enclosure 30, the outer circumferential surface of the enclosure 30 and the inner circumferential surface of the reinforcing dovetail plate 41 may have a clearance due to the roundness tolerance (not shown) The diffusion bonding material may be injected into the gap so that the reinforcing dovetail plate 41 and the enclosure 30 can be joined firmly without any gap.

When the reinforcement dovetail plate 41 is coupled to the enclosure 30 and air-cooled in the form of heat shrinking, the reinforcement dovetail plate 41 returns to its original size and tightly tightens the outer circumferential surface of the enclosure 30. As described above, when the enclosure 30 vibrates itself, a low-frequency noise is generated. Since the low-frequency noise diffuses greatly and propagates far away, it is a main cause of noise damage. However, if the reinforcing dovetail plate 41 is tightly fitted on the outer circumferential surface of the enclosure 30 in the form of heat shrinking, the vibration of the enclosure 30 is remarkably attenuated and the amplitude of the vibration is greatly reduced.

Preferably, the vertical reinforcing portion 50 connects the reinforcing dovetail plates 41 to further enhance the vibration damping effect by the reinforcing dovetail plate 41.

2, 5 and 6, one side of the vertical reinforcing portion 50 is formed to correspond to the shape of the outer peripheral surface of the enclosure 30 and vertically connects the reinforcing dovetail plates 41 .

In this case, as in the two embodiments shown in Fig. 6, the plate constituting the vertical reinforcement portion 50 may have a plurality of horizontal slits into which the reinforcing dovetail plate 41 can be inserted, or a plurality of short slits The plates can form the vertical reinforcement 50.

The vertical reinforcement 50 may be integrally connected to at least one of the reinforcing dovetail plates 41. As a result, the vibration of each reinforcing dovetail plate 41 is canceled with each other between the reinforcing dovetail plates 41, so that the vibration of the enclosure 30 is further attenuated. These effects will be described later with reference to the graphs shown in Figs. 9 to 11.

On the other hand, a vibration damper 60 may be attached to the outer circumferential surface of the enclosure 30 as shown in FIGS. The vibration damping material 60 is a member that acts to reduce vibration by damping vibration energy by moving with an oscillating object using the damping characteristics of the material.

Since the vibration damping material 60 is made of a viscoelastic material of a polymer, vibration of the vibration damping material 60 is suppressed. The material used as the vibration damping material 60 may be an asphalt sheet. When the polymer viscoelastic material is externally stressed and removed, the vibrational energy is transformed into heat energy by the friction between the molecules until it returns to its original position due to the ripple phenomenon.

In the case of the single layer type, the externally applied vibration energy is mainly absorbed by the tensile compression of the damping layer, and the two-layer type is absorbed by the shearing deformation of the damping layer . At this time, when the enclosure vibrates, the vibration damper (60) attached to the enclosure undergoes expansion and contraction, and the vibration energy is converted into heat energy and vibration damping occurs.

The vibration damping performance of the vibration damping material 60 has a temperature dependency. When the vibration damping material 60 is of a single layer type, the effective temperature is 10 to 40 degrees Celsius, and in the case of the double layer type, 10 to 60 degrees. Therefore, the vibration damping material 60 preferably has a double layer structure.

On the other hand, although not shown, an additional case may be provided outside the enclosure for thorough attenuation of noise. The additional case surrounds the outer circumferential surface of the enclosure so as to be spaced apart from the enclosure, and irregular protrusions for dispersing sound can be continuously formed on the inner circumferential surface of the additional case. These projections act to disperse the noise generated from the housing without resonance.

Hereinafter, a method of manufacturing the muffler of the present invention will be briefly described.

The manufacturing method of the muffle tower silencer comprises the steps of (S1) manufacturing a diffuser (10) having a gas discharge hole formed on the outer circumferential surface and communicating with the vent pipe at the upper end of the shielding tower, (S2) of forming a cylindrical inlet cell having an open top and connecting the inlet cell to the outer circumferential surface of the diffuser (10); a cylindrical body surrounding the inlet cell outer peripheral surface, the inlet cell being spaced apart from the inlet cell outer peripheral surface, (30) is assembled to the outer peripheral surface of the inlet cell (S3), and at least one reinforcing dovetail plate (41) as a hollow flat plate is fitted to the hollow of the reinforced donut plate (41) (S4) of securing the outer casing (41) to the outer circumferential surface of the enclosure (30).

At this time, after step S4 and after step S4, a plate material is formed in the longitudinal direction, one side of which is made to correspond to the vertical shape of the outer circumferential surface of the enclosure 30, and the reinforcing dovetail plate (S5) of forming a vertical reinforcing portion (50) by inserting the reinforcing dovetail plates (41) into the slots while attaching the one surface to the outer surface of the enclosure (30) in a vertical direction .

As shown in FIG. 4, the reinforcing dovetail plate 41 is inserted into the hollow of the reinforcing dovetail plate 41 while the reinforced dovetail plate 41 is heated to a predetermined temperature in step S4 as shown in FIG. 4, The reinforcing dovetail plate 41 strongly tightens the outer circumferential surface of the enclosure 30 when the reinforced dovetail plate 41 is air-cooled by the engagement of the enclosure 30 so that the noise due to the vibration of the enclosure 30 is remarkably attenuated do.

In order to maximize the tightening effect of the reinforcing dovetail plate 41 when fabricating the reinforced dovetail plate 41, the inner diameter of the reinforcing dovetail plate 41 is made smaller than or equal to the outer circumferential face of the enclosure 30 at the position where the reinforcing dovetail plate 41 is engaged .

The step S6 of attaching the vibration damper 60 to the outer circumferential surface of the enclosure 30 may be further added after the step S4 of fixing the reinforced donut plate 41 to the outer circumferential surface of the enclosure 30. [ At this time, the vibration damping material 60 can significantly attenuate vibrations at a medium and low frequency which can not be controlled by the reinforcing dovetail plate 41 and the vertical reinforcing part 50.

The results of experiments showing the degree of noise attenuation by the muffle tower silencer according to the present invention are shown in the graphs of FIGS.

9 is the magnitude of vibration of the vibration-damping silencer tested on the left without applying the horizontal reinforcement 40 and the vertical reinforcement 50. The graph on the right of FIG. 9 shows the magnitude of vibration of the horizontal reinforcement 40 and vertical And the magnitude of vibration in the state where the reinforcing portion 50 is applied.

9, the graph on the left shows the maximum value and the minimum value of the vertical axis are 100 m / sec2 and -100 m / sec2, respectively, while the graph on the right shows the maximum value and the minimum value of the vertical axis are 20 m / sec2. Accordingly, when the horizontal reinforcing portion 40 and the vertical reinforcing portion 50 are applied, it is understood that the noise is remarkably attenuated by reducing the amplitude by about four times.

The graph of FIG. 10 also shows results similar to FIG. The graph of FIG. 11 shows a frequency analysis graph before and after the horizontal reinforcing portion 40 and the vertical reinforcing portion 50 are applied. The upper graph of FIG. 11 shows the results obtained before the horizontal reinforcing portion 40 and the vertical reinforcing portion 50 were applied. Compared with that after the horizontal reinforcing portion 40 and the vertical reinforcing portion 50 were applied, It can be seen that the vibration is remarkably attenuated. Therefore, according to the muffle tower muffler according to the present invention, it can be seen that both the magnitude of the vibration and the low frequency vibration can be remarkably attenuated as compared with the muffler muffler using only the conventional diffuser or sound absorber.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the inventions. It will be apparent to those of ordinary skill in the art.
