Abstract
The utility model relates to a natural gas emptying device, which comprises an inner cylinder, an outer cylinder, a flame arrester and an igniter, wherein the bottom of the outer cylinder is connected to a natural gas pipeline through a connecting pipe, the inner cylinder is arranged in the outer cylinder and is connected with the connecting pipe, and the side wall of the inner cylinder is a noise elimination screen plate with a plurality of pore channels; the upper end of the outer barrel is connected with the flame arrester, and the igniter is arranged on the outer side wall of the outer barrel and is opposite to the outlet end of the flame arrester. The utility model discloses a noise elimination otter board forms the noise elimination interception effect to high-pressure natural gas to the lug that the air current can strike the urceolus inner wall further reduces the kinetic energy of gas molecule, what produce when effectively reducing the operation of unloading device squeals.
Description
Technical Field
The utility model relates to a natural gas emptying devices.
Background
When the pipeline transports the natural gas overpressure and the pipeline equipment needs to be maintained, the natural gas in the pipeline needs to be emptied through the emptying device, and the equipment safety is ensured. When the existing emptying device works, the high pressure in the pipeline can generate severe noise in the emptying device, and a noise pollution source is formed for a production living area near the emptying device.
Disclosure of Invention
An object of the utility model is to solve above-mentioned problem, provide a natural gas emptying devices, specifically realize by following technical scheme:
a natural gas emptying device comprises an inner cylinder, an outer cylinder, a flame arrester and an igniter, wherein the bottom of the outer cylinder is connected to a natural gas pipeline through a connecting pipe, the inner cylinder is arranged in the outer cylinder and connected with the connecting pipe, and the side wall of the inner cylinder is a silencing screen plate with a plurality of pore channels; the upper end of the outer barrel is connected with the flame arrester, and the igniter is arranged on the outer side wall of the outer barrel and is opposite to the outlet end of the flame arrester.
The natural gas emptying device is further designed in that a plurality of convex blocks opposite to the silencing screen plate are distributed on the inner wall of the lower part of the outer barrel.
The natural gas emptying device is further designed in that the inner wall of the upper part of the outer cylinder is arc-surface-shaped.
The natural gas emptying device is further designed in that a cooling sleeve is arranged on the upper side wall of the outer barrel, and the flame arrester is arranged on the cooling sleeve.
The natural gas emptying device is further designed in that a cooling water pore channel is arranged in the cooling sleeve.
The beneficial effects of the utility model reside in that:
the utility model discloses a noise elimination otter board forms the noise elimination interception effect to high-pressure natural gas to the lug that the air current can strike the urceolus inner wall further reduces the kinetic energy of gas molecule, what produce when effectively reducing the operation of unloading device squeals.
Drawings
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
the natural gas emptying device comprises an inner cylinder 1, an outer cylinder 2, a flame arrester 3 and an igniter 4, wherein the bottom of the outer cylinder is connected to a natural gas pipeline through a connecting pipe 5, the inner cylinder is arranged in the outer cylinder and connected with the connecting pipe, and the side wall of the inner cylinder is a silencing screen plate 11 with a plurality of pore channels; the upper end of the outer barrel is connected with the flame arrester, and the igniter is arranged on the outer side wall of the outer barrel and is opposite to the outlet end of the flame arrester.
When the pressure relief valve is used, the pressure relief valve connected with the connecting pipe 5 is opened when overpressure occurs, natural gas enters the inner cylinder 1 through the connecting pipe, the high-pressure natural gas collides with the side wall of the inner cylinder through a pore channel of the silencing screen plate and finally passes through the flame arrester from the upper part of the outer cylinder to be discharged, and the igniter 4 is matched to avoid the detonation danger caused by local gathering of the natural gas. The utility model discloses a noise elimination otter board forms noise elimination interception effect to high-pressure natural gas flow.
And a plurality of lugs 6 opposite to the silencing screen plate are distributed on the inner wall of the lower part of the outer barrel. The air flow can impact the bumps on the inner wall of the outer barrel to further reduce the kinetic energy of air molecules, and effectively reduce squeak generated during the operation of the emptying device.
The inner wall of the upper part of the outer cylinder is arc-surface-shaped, and the kinetic energy of gas molecules is further reduced while the arc-surface-shaped inner wall guides natural gas to flow to the flame arrester.
And a cooling sleeve 7 is arranged on the upper side wall of the outer barrel, and the flame arrester is arranged on the cooling sleeve. The cooling jacket is internally provided with a cooling water pore channel 71; thereby cooling cover both can reduce the urceolus internal temperature and meet cold decompression when making the natural gas get into the urceolus inside, can reduce the temperature of spark arrester again, ensures that spark arrester operating condition is normal.
