Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a steam drain silencer.
[0002]
[Prior art]
In general, in a boiler plant, as shown in FIG. 3, a part of the steam generated in the boiler body 1 is supplied to a desired facility in the plant via a service steam pipe 2 and used. In this case, however, the service steam pipe 2 may be bent and arranged to avoid structures in the plant, as in the case of normal pipes. Vapor drain tends to stay in the tank.
[0003]
For this reason, a steam drain pipe 3 is connected to a required location in the middle of the service steam pipe 2, a steam trap 4 is provided at the end of the steam drain pipe 3, and the steam drain discharged from the steam trap 4 is placed in the side groove 5 or the like. By directly discharging, steam drain is prevented from staying in the service steam pipe 2.
[0004]
[Problems to be solved by the invention]
However, as described above, when the steam drain is directly discharged from the steam drain pipe 3 to the side groove 5 or the like, there is a problem that noise is generated and the steam drain is rebounded.
[0005]
In view of such circumstances, an object of the present invention is to provide a steam drain silencer that can suppress the generation of noise at the time of steam drain discharge and can prevent the steam drain from rebounding.
[0006]
[Means for Solving the Problems]
The present invention provides a silencer body in which a closing plate is fixed to an opening on one end side of a cylindrical body that is inclined with respect to the horizontal at a required angle, and an opening / closing lid is detachably attached to the opening on the other end side of the cylindrical body. ,
Steam drain for projecting steam drain piping to be connected to the required location on the top of the silencer body, and for allowing steam drain separated from steam discharged from the steam trap through the steam drain piping to flow into the silencer body. A piping nozzle;
A silencer for filling the silencer body, and for eliminating noise caused by steam drain flowing into the silencer body;
A steam drain discharge seat for discharging the steam drain, provided at a required position at the lower end of the silencer body,
The sound deadening material is a stainless steel chip-like member,
The present invention is directed to a steam drain silencer characterized in that the silencer can be replaced by opening an open / close lid of the silencer body.
[0007]
[0008]
[0009]
According to the above means, the following operation can be obtained.
[0010]
The steam drain separated from the steam discharged from the steam trap through the steam drain pipe flows into the silencer main body from the steam drain pipe nozzle, but the silencer main body is filled with a sound deadening material. The silencer weakens the momentum of the steam drain and suppresses the generation of noise, and the steam drain gently flows down in the inclined silencer body and is discharged from the steam drain discharge seat to the side groove, etc. Released.
[0011]
As a result, compared with the conventional case where steam drain is directly discharged from the steam drain pipe to the side groove or the like, no noise is generated and the steam drain does not rebound, and it is a light and simple structure. The cost is also cheap.
[0012]
In the steam drain silencer, since the sound deadening material is made of stainless steel chips, there is no fear that rust or the like is generated in the sound deadening material.
[0013]
Further, in the steam drain silencer, when such deterioration of sound-deadening material with use for a long period of time is concerned, by opening the lid, it is possible to replace the sound-deadening material from the opening On the other hand, the inside of the silencer body can also be checked.
[0014]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0015]
1 and 2 show an example of an embodiment of the present invention. In the figure, the same reference numerals as those in FIG. 3 denote the same parts, and a cylindrical silencer body 6 with both ends closed is shown. A steam drain pipe nozzle 8 connected to the steam drain pipe 3 is projected at a required position on the silencer body 6 at a required angle with respect to the horizontal by the leg member 7, and the silencer is inserted into the silencer body 6. A silencer 9 for eliminating noise caused by steam drain flowing into the main body 6 is filled, and a steam drain discharge seat 10 for discharging the steam drain to the side groove 5 or the like is provided at a required position at the lower end of the silencer body 6. Thus, a steam drain silencer is configured.
[0016]
In the case of this illustrated example, the silencer body 6 is fixed by welding a closing plate 13 to an opening 12 on one end side of a cylindrical body 11 such as a steel pipe, and a flange at the edge of the opening 14 on the other end side of the cylindrical body 11. 15 is welded and fixed, and an open / close lid 16 such as a blind flange is detachably attached to the flange 15 by a bolt / nut 17. The open / close lid 16 is opened as necessary. Thus, the silencer 9 can be replaced.
[0017]
Further, the sound deadening material 9 is a stainless-steel chip-like member so that rust and the like are not generated.
[0018]
FIG. 1 shows an example in which two steam drain piping nozzles 8 are provided protruding from the silencer main body 6. However, the number of the steam drain piping nozzles 8 may be one or more if necessary. Needless to say, it may be more than one.
[0019]
Next, the operation of the illustrated example will be described.
[0020]
The steam drain separated from the steam discharged from the steam trap 4 through the steam drain pipe 3 flows into the silencer body 6 from the steam drain pipe nozzle 8, and the silencer body 6 is filled with a silencer 9. Therefore, the silencer 9 weakens the momentum of the steam drain and suppresses the generation of noise. The steam drain gently flows down through the inclined silencer body 6 to discharge the steam drain. It is discharged from the seat 10 and discharged to the side groove 5 or the like.
[0021]
As a result, compared to the case where the steam drain is directly discharged from the steam drain pipe 3 into the side groove 5 or the like as in the prior art, no noise is generated and the steam drain does not rebound, and the light weight and simple structure. Because it is, the cost is low.
[0022]
Further, since the sound deadening material 9 is a stainless steel chip-like member, there is no fear that rust or the like is generated.
[0023]
Furthermore, in the case where there is a concern about deterioration of the sound deadening material 9 due to use over a long period of time, it is possible to replace the sound deadening material 9 from the opening 14 by opening the opening / closing lid 16. Inspecting the silencer body 6 and the like can also be performed.
[0024]
In this way, it is possible to suppress the generation of noise at the time of steam drain discharge and to prevent the splashing of the steam drain, and to prevent the occurrence of rust etc. by using the sound deadening material 9 as a stainless steel chip-like member. Furthermore, the silencer 9 can be replaced and the silencer body 6 can be inspected by opening and closing the opening / closing lid 16.
[0025]
Note that the steam drain silencer of the present invention is not limited to the above-described illustrated example, and it is needless to say that various changes can be made without departing from the gist of the present invention.
[0026]
【The invention's effect】
As described above, according to the steam drain silencer according to the first aspect of the present invention, as described, to give suppressing the occurrence of noise at the time of steam drain discharge, and rebound like obtained also prevent the steam drain, also, the sound-deadening material By using stainless steel chips, it is possible to prevent the occurrence of rust, etc., and also, by opening and closing the open / close lid, the silencer can be replaced and the silencer body can be inspected. obtain.
