Description
Technical field
The utility model relates to equipment therefor in a kind of mine gas extraction pipeline, is specially the mine gas extraction pipeline with the novel scummer that dewaters
Background technology
China is that the most serious country occurs the mine gas disaster in the world, and the Gas Disaster total degree of generation accounts for half of Coal Mine Disasters total degree.An important technical during mine gas is administered is that coal-bed gas is carried out extraction, namely by the some extraction boreholes of construction in the coal seam, after drilling construction is complete, the access extraction arms such as hole sealing tube, tailrace, connecting hose are installed are carried out the extraction of coal-bed gas, so as to reducing coal seam gas-bearing capacity, ensure the safe back production of mine working face.
Whether the reasonable operation of extraction system, not only is related to the quality of extracting result, closely affects the Gas of mine simultaneously, and then have influence on the safety in the coal mine excavation process.Therefore, accurately the operational factor of monitoring extraction pipe network seems particularly important, but because the particularity of conditions down-hole, there are more steam, grit in the extraction gas, elongated along with extraction time and fed distance, accumulating gradually in the pipeline has more ponding and cinder, not only increase the running resistance of extraction pipe network, reduce the efficient of whole extraction system operation, may cause corrosion to the gas pumping pump, also badly influence measuring accuracy and the length of service of some metrical instruments, instrument.Therefore, the ponding, the accumulated slag problem that solve in the mine extraction process pipeline have very strong realistic meaning.But the deslagging device principle that dewaters of at present mine use is comparatively simple, and effect of its slagging-off that dewaters is all undesirable.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, cheap, effective mine gas extraction pipeline of slagging-off that dewaters with the novel scummer that dewaters.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of mine gas extraction pipeline comprises conical eliminator with the novel scummer that dewaters, and the tangential direction on the top of described eliminator is provided with intake interface, and the upper end of described eliminator is provided with the interface of giving vent to anger, and the lower end is slag notch.
Further, described slag notch place is connected to slag ladle, and this slag ladle bottom is provided with lets out the slag door.
Further, the lower semisection of described slag ladle is conical.
Further, described slag ladle is provided with telescoping shoring column.
Further, described cone separator is provided with containment vessel, and described containment vessel is divided into upper chamber and lower chambers by separate layer; described eliminator vertically is fixed in the upper chamber; described intake interface and the interface of giving vent to anger is the pierce through the protection shell respectively, is exposed to outside the containment vessel, and the bottom of described lower chambers is provided with ash gate.
Further, the lower semisection of described lower chambers is conical.
Further, described containment vessel is provided with telescoping shoring column.
The utility model principle:
Dusty gas tangentially enters from air inlet port, is subjected to the constraint of wall for the helical movement along the eliminator inwall downwards.Under the centrifugal inertial force effect, particle is thrown to wall, and air-flow is still at internal layer, has tentatively realized separating of particle and air-flow, and particle drops down onto the cone slag notch at the end along wall under Action of Gravity Field, enter storage slag space.Air-flow is at tapered segment, and radius of gyration is dwindled and the tangential velocity increase, continues for the helical movement downwards.Near the bottom of circular cone, after air-flow was fully purified, transferring to rises rotatablely moved, and is discharged by the gas outlet, top at last.
Compared with prior art the technical program has following beneficial effect:
1, agent structure of the present invention is simple, and is cheap, do not have movable part, available multiple material manufacturing, and operating condition haves a wide reach;
2, outside just as etc. under the big or small condition, separative efficiency of the present invention has obvious lifting than existing apparatus, through experimental verification, its separative efficiency can reach more than 90%;
3, the present invention both can be used for down-hole extraction negative pressure, the slagging-off that dewaters when also can be used for malleation conveying gas;
4, at the eliminator covering containment vessel is housed, both can plays a protective role to the deslagging bucket, simultaneously, its lower chambers can be used to store water and the slag that eliminator is discharged;
5, the conical design of the lower semisection of slag ladle lower chambers can be eliminated its inner dead angle, makes deslagging cleaner.
6, the present invention is light small and exquisite, is provided with telescoping shoring column, can be used for fixing and adjusting the setting height(from bottom) of the scummer that dewaters, and is better to on-the-spot compliance, and artificial only the need get final product according to the regular draining deslagging of field condition.
