Abstract
The utility model provides a kind of blowout prevention filter device for gas drilling construction, first the mixture of spray volume methane gas, cinder and sewage is depressured the mixture of a large amount of high concentration gas gases and cinder, coal dust that are generated during drilling construction in anti-storehouse device to hole, and carry out the separation of vapour and water, slag, gas enters after extraction pipeline, water and slag are detached using filter device flows into drainage system again.The utility model effectively prevents gas exceeding limit in work progress and spray orifice accident occurs and damage of the waste water to draining pump in firedamp taking-out discharging drilling work progress.
Description
Technical field
The present invention relates to a kind of mine gas drilling construction safety protection devices, and in particular to one kind is applied for gas drilling
The blowout prevention filter device of work.
Background technology
China Mine Geological condition is extremely complex, and 95% is pit mining, 70% or more state-owned coal mines be high methane, coal with watt
This projecting mine, with being continuously increased for mining depth, mine gas content also increases therewith with pressure, control of coalmine gas work
Degree of feeling embarrassed increasingly sharpens, and firedamp taking-out discharging drilling of constructing is most effective mash gas harnessing method, but firedamp taking-out discharging drilling was constructed
Gas exceeding limit and the empty casualty accident of spray are easily caused in journey again, great hidden danger is brought to safety in production.
In firedamp taking-out discharging drilling work progress, what is be discharged out of drilling is not only the methane gas containing high concentration, together
Shi Hanyou largely constructs cinder, the coal dust of generation, and gas is unprocessed, enters extraction through protrusion-dispelling guiding device in existing structure
Pipeline easily causes pipeline blockage although gas exceeding limit in work progress can be solved the problems, such as, increases gas control difficulty.
Utility model content
Technical problem to be solved in the utility model is：In firedamp taking-out discharging drilling work progress, what is be discharged in hole is a large amount of
The mixture of high concentration gas gas and cinder, coal dust directly enters releasing pipe if unprocessed through protrusion-dispelling guiding device
Pipeline blockage is easily caused on road.
In view of the above technical problems, the technical solution that the utility model is taken is：It provides a kind of for gas drilling
The blowout prevention filter device of construction, the mixing for a large amount of the high concentration gas gases and cinder, coal dust that drilling construction generates in the process
First the mixture of spray volume methane gas, cinder and sewage is depressured object in anti-storehouse device to hole, and carries out vapour and water, slag
Separation, gas enters after extraction pipeline, water and slag are detached using filter device flows into drainage system again.
The rectangular configuration babinet that the blowout prevention filter device overall structure is welded by anti-corrosion steel plate, the babinet point
For anti-storehouse and filtering cabin, wherein anti-storehouse is higher than filtering cabin, in anti-storehouse by leading at the top of gas collection end cap and unidirectional anti feedback valve
It crosses steel pipe connecting and is connected to flange arrangement；Feature and resistance analysis are filtered according to water-coal-slurry, filtering cabin is low flow resistance, supercharging semitight
Formula water-coal-slurry filter device, filtering cabin are made of three segmentation warehouses, wherein by coal water sieve between a Room and two Room, to protect
Some strength and antirust are demonstrate,proved, it is filter core rotating room that filter screen, which uses stainless steel material, third room, and filter core is by Special clay ceramic ring
It is made, it is reusable.
The front and back of the entire babinet of blowout prevention filter device is connected to flange arrangement by steel pipe connecting.
The utility model advantageous effect is：In firedamp taking-out discharging drilling work progress, a large amount of high concentrations watt of discharge in hole
The mixture of this gas and cinder, coal dust first enters back into extraction pipeline after blowout prevention filter device is detached, and waste water passes through
Filter enters drainage system, and the damage with waste water to draining pump occurs for gas exceeding limit and the spray orifice accident in work progress of effectively preventing
Evil.
Description of the drawings
Fig. 1 is blowout prevention filter apparatus configuration schematic diagram provided by the utility model；
In figure：1,1# flanges；2,2# flanges；3, unidirectional anti feedback valve；4, blowout prevention baffle；5, coal water sieve；6, it filters
Filter core；7,3# flanges.
Specific implementation mode
As shown in Figure 1, the utility model provides a kind of blowout prevention filter device for gas drilling construction, structure is such as
Under, the present apparatus is welded into rectangular configuration babinet by 3 millimeters of steel plates, is divided into anti-storehouse and filtering cabin, wherein anti-storehouse is higher than filtering
Storehouse, anti-storehouse is interior to be equipped with unidirectional anti feedback valve 3 and blowout prevention baffle 4；Coal water sieve 5 and filter core 6, dress are equipped in filtering cabin
External three pipeline connecting flanges are set, wherein 1# flanges 1 are connect with opening arrangement, and 2# flanges 2 are connect with gas drainage pipeline, 3#
Flange 7 is connect with two-stage filter.
