Description

Water seal flame arrester

Technical Field

The utility model relates to a safety device for preventing the flame of inflammable gas from spreading and preventing the explosion caused by backfire, in particular to a water seal flame arrester.

Background

Water seal flame arrestors are safety devices used to stop the spread of a flame of flammable gases and to prevent explosions due to flashback. Are typically installed in pipelines that carry or discharge flammable and explosive gases, such as heating combustion systems, petroleum gas recovery systems, especially coal mine gas environments and other flammable gas systems. If the local climate is cold, the heat tracing device can be arranged outside.

SUMMERY OF THE UTILITY MODEL

The utility model provides a water seal fire arrestor for solving the problems existing in the prior art.

The technical scheme of the utility model is realized like this:

a water-sealed flame arrester comprising: the air conditioner comprises a shell, an air inlet, an air outlet pipe, a water inlet pipe, an overflow pipe, a water seal tank, a clean discharge port, an inspection hole blind plate and the like. The casing lower extreme is equipped with the inspection hole blind plate the casing front portion is equipped with the air intake still be equipped with tuber pipe, inlet tube and overflow pipe in the casing, the air outlet that goes out the tuber pipe is located the outside of casing, the inlet tube is located go out tuber pipe one side and the play water outlet end of inlet tube lower extreme is located the casing lower part, the overflow pipe is located one side of inlet tube and its lower extreme are followed the casing lower extreme extends, the overflow pipe lower extreme is located the water seal inslot.

Furthermore, a clean discharge opening is also arranged at the lower part of the other side of the shell.

Furthermore, the upper plane of the overflow port is higher than the lowest end of the air outlet pipe.

Furthermore, the upper part of the water seal tank is also provided with an overflow port of the water seal tank, and the overflow port of the water seal tank is higher than the lowest end of the overflow pipe.

The utility model has the advantages that: the utility model can prevent the flame of inflammable gas from spreading and preventing backfire to cause explosion, and can realize automatic pollution discharge.

Drawings

In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without creative efforts.

Fig. 1 is a schematic structural view of the present invention;

fig. 2 is a top view of the present invention.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1-2, the water-sealing flame arrester comprises: casing 1, be equipped with inspection hole blind plate 11 at 1 lower extreme of casing, be equipped with air intake 2 at 1 front portion of casing, still be equipped with tuber pipe 4 in casing 1, inlet tube 5 and overflow pipe 8, the air outlet 3 that goes out tuber pipe 4 is located the outside of casing 1, inlet tube 5 is located tuber pipe 4 one side and the play water end of inlet tube 5 lower extreme is located casing 1 lower part, overflow pipe 8 is located one side of inlet tube 4 and its lower extreme outwards extends from casing 1 lower extreme, 8 lower extremes of overflow pipe are located water seal tank 9, still be equipped with in the lower part of 1 opposite side of casing and put clean mouth 10.

The upper plane of the overflow opening 7 in the horizontal direction is higher than the lowest end of the air outlet pipe 4.

The upper part of the water seal tank 9 is also provided with a water seal tank overflow port 12, and the water seal tank overflow port 12 is higher than the lowest end of the overflow pipe 8.

Before the water seal flame arrester operates, a valve of the water inlet 6 needs to be opened, water is injected into the water seal flame arrester until the water seal flame arrester generates overflow, the water enters the water seal groove 9 from the overflow port through the overflow pipe 8, and after the water is filled, the valve of the water inlet pipe 5 can be closed when the overflow port 12 of the water seal groove overflows.

The air inlet 2 is in positive pressure, the air outlet 3 of the air outlet pipe 4 is in negative pressure, and the horizontal height difference between the lower plane of the air outlet pipe 4 and the overflow port 7 determines the pressure difference (1 mmH) of the air inlet 2 of the air outlet 3₂O10 Pa), when the pressure difference between the air outlet 3 and the air inlet 2 is greater than the pressure difference (mmH) of the water seal₂O), the asphalt smoke breaks the water pressure from the lower plane of the air outlet pipe 4, the air bubbles enter the air outlet pipe 4 to realize continuous exhaust, part of light asphalt oil can be removed by the asphalt smoke through the water bath, and the light asphalt oil enters the overflow pipe 8 through the overflow port 7 to be automatically discharged and flows into the water sealIn the groove 9, the water level between the overflow pipe 8 and the overflow port 12 of the water seal groove must be higher than the water level between the lower plane of the air outlet pipe 4 and the overflow port 7, so as to ensure that the water seal does not release pressure.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
