Description
Technical field
The invention belongs to water coal separation tailrace field more particularly to a kind of gas drainage pipeline air water coal separators.
Background technique
In the tunneling process of lane, (5m is reached since gas emission is big3/ min) influence being normally carried out for excavation operation.It is effective
Reduce return gas density, it is ensured that tunnel safety driving, if usually in digging laneway coal side, arrangement intervention is taken out at regular intervals
Drilling, connection extraction pipeline carry out pre-mining drainage using drainage pump.Extraction process is being carried out to drilling using gas drainage pipeline
In, in addition to having coal seam gas extraction, it is often accompanied by cinder and crevice water outflow, such as handles not in time, on the one hand causes extraction
Bye-pass blocking, extraction pipeline is obstructed, leads to pipeline ponding；On the other hand since water increase will affect extraction supervisor
The negative pressure on road causes negative pressure unstable.
Existing air water coal separator includes pallet, side guide rod, magnet, centre pilot bar, outer cylinder, discharge water valve protection
Cover, discharging valve, guide holder, buoy, filter vat etc., structure is complex, higher cost.In addition, air water coal separator occurs
After damage, replacement components are relatively complicated and time-consuming and laborious, delay the separation of air water coal.
It can be seen that the existing technology needs further improvement and improves.
Summary of the invention
The present invention is that provide structure simple in place of avoiding above-mentioned the shortcomings of the prior art, convenient for operation and replacement
The gas drainage pipeline air water coal separator of components.
The technical scheme adopted by the invention is as follows:
A kind of gas drainage pipeline air water coal separator, including pressure-resistant square metal shell, sieve plate, intake valve, pumping
Hole, discharging valve.
The left-external side of pressure-resistant square metal shell is arranged in the intake valve, and intake valve is connected with gas drainage pipeline.
The right outside of pressure-resistant square metal shell is arranged in the aspirating hole, and aspirating hole is connected with gas drainage pipeline.
The sieve plate is fixed on the inner wall of pressure-resistant square metal shell, one of them is fixed on front housing half point
Closely connect on inner wall and with upper inner wall by welding manner, another is fixed on shell latter half inner wall, and with it is lower interior
Wall is at regular intervals.
The configuration of the present invention is simple, ingenious in design, during mash gas extraction, the mixture of gas and water coal is first taken out from intake valve
Enter in tailrace, after sieve plate, water cinder is deposited on tailrace bottom, and the gases such as gas are inhaled through top line portals
It walks, the water cinder of deposition is discharged by discharging valve again, thus the operation for completing extraction, separating, discharging water, and then efficiently solve
Pipeline blockage, pipeline ponding, the problems such as negative pressure is unstable.
By adopting the above-described technical solution, obtained by the present invention have the beneficial effect that
1, in the tunneling process of lane, return gas density is effectively reduced, it is ensured that tunnel safety driving is no longer helped in digging laneway coal
When arrange several pre-draining boreholes at regular intervals, connection extraction pipeline utilizes drainage pump to carry out pre-mining drainage.It is taken out using gas
During pipeline is put to drilling progress extraction, in addition to having coal seam gas extraction, it is often accompanied by cinder and crevice water outflow, this hair
Bright thoroughly to solve the blocking of extraction bye-pass, extraction pipeline is obstructed, leads to pipeline ponding.
2, in terms of safe handling, solving water increase will affect the negative pressure of extraction main line, cause negative pressure unstable
The problems such as, safe effect is preferable.
3, the configuration of the present invention is simple, ingenious in design, low manufacture cost substantially increases gas drainage efficiency, overcomes perhaps
More drawbacks can be promoted the use of in similar coal bed gas drainage.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
