Abstract
The utility model is related to noise control technical field in a kind of low temperature muffler, category oil field system and pressure vessel pressure leak process.The low temperature muffler includes hush pipe, sleeve pipe, hush pipe is round tube shape, one end is welded with the first flange for being connected with pressure vessel, ring week is evenly equipped with noise reduction through hole in the middle part of hush pipe, at the pipeline section of noise reduction through hole in the middle part of hush pipe, sleeve pipe, sleeve pipe two ends and noise reduction duct occlusion are set with, annular silencing cavity is formed.In safety valve opens pressure leak process, by bloop, sound-absorbing storehouse and low temperature acoustical cotton collective effect, reduce oil field system or Pressure-Container-Exceeding Pressure opens the noise pollution that safety valve pressure release triggers, good muffling effect, and make simple, it is easy to operate.
Description
Technical field
The utility model is related to noise control skill in a kind of low temperature muffler, category oil field system and pressure vessel pressure leak process
Art field.
Background technology
In oil field system and pressure vessel running, when operating pressure exceedes setting, safety valve opens pressure release, from
And ensure system and pressure vessel and normally run.Under normal circumstances, safe valve outlet only connects blow-down pipe, in safety valve pressure release
Cheng Zhong, noise pollution is serious, especially night, disturbs resident's normal life nearby and rest, individual pressure container is in the external world
When environment temperature is higher, pressure release frequency is higher, during such as carbon dioxide injection, feeds liquid pump pressurized circulation, and carbon dioxide storage tank surpasses
Pressure causes safety valve pressure release frequently, and noise pollution causes resident's kickback nearby, has damaged the image of oilfield enterprise.To alleviate
Contradiction between the noise pollution and neighbouring resident's normal life that are produced in production process, to spend very big energy and time with
Neighbouring resident links up, and is even forced night stopping production when serious, have impact on the normal operation of oil field production, be produced into while adding
This.
The content of the invention
The purpose of this utility model, be in order to overcome noise pollution caused by safety valve pressure release present in prior art,
And there is provided one to the influence brought is normally produced for the contradiction between the oil field production because of noise pollution initiation and resident nearby
Plant simple in construction, make easy, installation, easy to use, the low temperature muffler of good muffling effect.
Low temperature muffler of the present utility model, including hush pipe, sleeve pipe, hush pipe is round tube shape, and one end is welded with use
In the first flange being connected with pressure vessel, ring week is evenly equipped with noise reduction through hole in the middle part of hush pipe；Noise reduction in the middle part of hush pipe is led to
At the pipeline section in hole, sleeve pipe, sleeve pipe two ends and noise reduction duct occlusion are set with, annular silencing cavity is formed.
Low temperature acoustical cotton is packed with the annular silencing cavity, for improving noise reduction.
Ring support is installed between described sleeve pipe and hush pipe.
Described sleeve pipe one end and hush pipe welded closure, one end is connected by second flange and closed, is convenient for changing annular and disappear
The low temperature acoustical cotton of sound intracavitary.
The utility model is opened in safety valve in pressure leak process, by bloop, sound-absorbing storehouse and low temperature acoustical cotton collective effect,
Reduce oil field system or Pressure-Container-Exceeding Pressure opens the noise pollution that safety valve pressure release triggers, good muffling effect, and make letter
It is single, it is easy to operate.
Brief description of the drawings
Fig. 1 is the utility model topology view；
Fig. 2 is the utility model Section A-A view.
Embodiment：
As seen from Figure 1, Figure 2, low temperature muffler of the present utility model, including hush pipe 1, sleeve pipe 2, hush pipe 1 are pipe
Shape, one end is welded with the first flange 4 for being connected with pressure vessel, and noise reduction through hole is evenly equipped with the middle part ring week of hush pipe 1
8；At the pipeline section of the noise reduction through hole 8 at the middle part of hush pipe 1, sleeve pipe 2 is set with, the two ends of sleeve pipe 2 are closed with hush pipe 1, forms annular
Silencing cavity 7.
Low temperature acoustical cotton 6 is packed with described annular silencing cavity 7, noise reduction can be improved.
Ring support 3 is installed between described sleeve pipe 2 and hush pipe 1.
Described one end of sleeve pipe 2 and the welded closure of hush pipe 1, one end is connected by second flange 5 and closed, conveniently replaced
Low temperature acoustical cotton 6 in annular silencing cavity 7.
The utility model is connected with the safety valve on field pressure container, forming annular with sleeve pipe 2 by hush pipe 1 disappears
The noise that the collective effect of the low temperature acoustical cotton 6 of filling in sound chamber 7 and its cavity, effectively reduction are triggered by safety valve pressure release is dirty
Dye.
