Description

Silence for a gas diffusion

The present invention relates to a movable gas silencer, and more particularly to a movable gas silencer capable of effectively reducing the noise of gas emitted during the operation of replacing or expanding piping or valves for gas supply.

(Piping) replacement (change) of the relevant valve (piping) after constructing the branch and bypass line in the piping which is already supplied in relation to the improvement / replacement of piping and valves for gas supply, And valve internal leakage check. In this process, the ventilation hose is connected to the working section which cuts off the relevant section and the gas of the section to dissipate in the air.

Noise is generated in the process of gas dissipation, which hinders the work environment and causes damage to the operator's hearing loss.

As a prior art for preventing the noise during the gas dissipation process, there has been proposed a method of reducing the noise level of a gas in a predetermined position on a gas piping connection pipe, as disclosed in Korean Patent No. 10-0962523 entitled " A diffuser pipe installed at an upper end of a vertically installed dissipation tower at a height of 20 to 30 m and a first chamber through which a gas discharged through a plurality of discharge holes formed in the diffuser pipe are introduced, An inlet cover installed to form a second chamber on the upper portion of the first sound absorbing member 130, an outer cover installed to form a discharge passage on the outer side of the inlet cell and the first sound absorbing member, A rainwater cover provided so as to prevent rainwater from flowing into the inside of the inlet cell provided inside, a plurality of sound absorbing holes formed at predetermined intervals, A sound absorbing material protection cloth attached to one side face of the sound absorbing material, a mesh network of a mesh type installed on the outer face of the sound absorbing material protecting cloth, and a plurality of And a perforated plate formed with a discharge hole and installed at the outer side of the wire net.

1, a corresponding pipe 20 requiring dissipation is connected to one side of the manifold 10 to slowly open the valve 11 to perform the dissipation, and the pipe 12 Thereby allowing the gas to escape.

However, such a conventional manifold type silencer has a structure in which gas is introduced into the manifold 10 which is expanded from the piping 20, and thus the aeration noise is still generated, which limits the improvement of the working environment.

Korean Patent Registration No. 10-0962523 "Silencer for Gas-Gas Tower" (Registered on June 3, 2010)

The present invention has been made in order to solve the above problems, and it is an object of the present invention to improve the working environment due to the high noise generated during the discharge during the maintenance work (valve leakage inspection, static pressure facility inspection, etc.) And to provide a portable gas silencer capable of greatly reducing noise to minimize the damage to the complaint of a residential area near the station.

According to the present invention, there is provided a silencer for reducing noise of exhaust gas discharged from a gas pipe of a gas facility,

A housing in an enclosed space having an inlet and an outlet,

A plurality of multi-attack plates partitioning the inside of the housing into a plurality of chambers and having a plurality of holes,

A first diffuser tube having one end supported by the inlet and connected to the gas pipe, the other end being supported through one of the multi-attack plates and having a plurality of holes formed in an outer circumferential surface thereof,

A second diffuser tube having one end connected to the other end of the first diffuser tube and having a relatively larger diameter than the first diffuser tube, a plurality of holes formed in the outer circumferential surface thereof, and the other end supported on the outlet side;

A discharge pipe connected to the second diffuser pipe,

And an end cap coupled to an upper end of the discharge pipe and having a plurality of holes.

Further, a sound absorbing material is attached to the inner wall surface of the housing.

This design silencer is equipped with the first and second offensive plates and the first and second diffuser pipes, so that the noise generated during the maintenance work (gas leakage inspection, static pressure facility inspection, etc.) And reduce the noise to minimize the damage to the complaints of the residents near the station.

FIG. 2 is a cross-sectional view showing a muffler of the present embodiment,
3 is a schematic perspective view of the main part of Fig.

The movable gas silencing silencer of the present embodiment enables the noise of the gas to be dissipated during the operation of replacing or expanding the piping or valve for gas supply to be effectively reduced.

2 and 3, which show the silencer of the present embodiment, this is to reduce the noise of the exhaust gas discharged from the gas piping 400 of the gas facility, A plurality of multi-attack plates (110, 120) dividing the inside of the housing (100) into a plurality of chambers (103, 104, 105) and having a plurality of holes; A first diffuser pipe 210 connected to the gas pipe 400 and having an opposite end supported by one of the multi-attack plates and having a plurality of holes formed in an outer circumferential surface thereof, a first diffuser pipe 210 having one end connected to the other end of the first diffuser pipe 210 A second diffuser pipe 220 connected to the first diffuser pipe 210 and having a relatively larger diameter than the first diffuser pipe 210 and having a plurality of holes formed on the outer circumferential surface thereof and the other end supported on the outlet 102 side; A discharge pipe 230 connected to the discharge pipe 220, Coupled to an end is provided with an end cap 240, a plurality of holes are formed.

A sound absorbing material 300 is attached to the inner wall surface of the housing 100 and a caster 500 is attached to the bottom surface of the housing 100 for easy movement.

When the first diffuser pipe 210 is connected to the gas piping 400 of the gas facility and the gas is dissipated, the high-pressure gas is introduced into the silencer, so that the holes of the first diffuser pipe 210 The first and second chambers 103 and 104 are firstly dissipated to attenuate the noise.

The gas dissipated into the first and second chambers 103 and 104 is diffused through the first and second multi-attack plates 110 and 120, thereby attenuating noise.

In addition, the gas passing through the first diffuser pipe 210 further attenuates the noise while passing through the second diffuser pipe 220 to be expanded, and further dissipates the noise in the third chamber 105 through the hole of the second diffuser pipe 220. [ Thereby further attenuating the noise.

The gas dissipated into the third chamber 105 is absorbed by the sound absorbing material 300 to attenuate vibrations and noise caused by the gas dissipation.

As described above, the gas that is dissipated inside the housing 100 and attenuated is discharged to the atmosphere via the discharge pipe 230 and the end cap 240.

Such silencers are used to improve the working environment due to the high noise generated during the discharge during the maintenance work (valve leakage check, static pressure facility check, etc.) requiring gas dissipation in the gas station and to minimize the noise So that it can be greatly reduced.
