Abstract
A coal gas purifier for a safety protection system for drilling and spraying orifice is characterized in that a dust collecting square box is arranged, the front side of the dust collecting square box adopts an openable slag removing door, an air inlet pipe and an air outlet pipe communicated with the dust collecting square box are arranged on two side walls of the dust collecting square box respectively, a baffle positioned in the front of an inlet flow channel is arranged in the dust collecting square box, and a sprayer is arranged and positioned above the inlet flow channel; and a filter screen is arranged at the airflow inlet of the air outlet pipe. In the underground construction, extracting and mining and drilling processes in coal mine, after massive methane gas and coal dust caused during the orifice spraying process are primarily shunted, the coal gas purifier is used for further purifying the methane gas mixed with a certain quantity of dust, so as to prevent the dust from entering a methane gas extracting and mining system with the methane gas together. The utility model has good use effect, can effectively prevent the coal dust from entering the methane gas extracting and mining pipeline, avoid the stoppage of the methane gas extracting and mining pipeline, ensures stable and reliable extracting and mining system and realizes high negative pressure connection extracting and mining operation.
Description
Technical field
The utility model relates to gas purifier, more specifically say so and be applied in the extraction borehole process of constructing under the coal mine, a large amount of gas and coal dust were after the preliminary shunting by process when spray orifice took place, further purify for the gas that is mingled with a certain amount of dust, with the gas purifier that stops dust together to enter the gas pumping system with gas.
Background technology
In the strong projecting coal bed boring procedure of construction, the spray orifice phenomenon is comparatively serious, and spray orifice is accompanied by a large amount of coals and high dense gas ejection drilling orifice in the short time, may work the mischief to mine and personal security.Have some some measures are arranged, be included in the drilling orifice place devices such as porous channel are set, can make the coal and the high dense gas of ejection obtain collecting and shunting, but,, still be mingled with a certain amount of coal dust in the gas after the shunting because spray orifice pressure is big, the coal dust that is mingled with enters the obstruction that the extraction system then causes the extraction pipeline with gas, can not realize the high negative pressure extraction that the extraction pipeline is reliable and stable, may cause gas accident, work the mischief still can for personnel and mine.
The utility model content
The utility model is for avoiding above-mentioned existing in prior technology weak point, a kind of drill hole spray safety protection system gas purifier is provided, in the hope of effectively separating for the coal dust that is mingled with in the gas, stop the coal dust coal dust to enter the gas pumping pipeline, avoid the obstruction of gas pumping pipeline, thereby guarantee that the extraction system stability is reliable, realize that high negative pressure connects extraction.
The utility model technical solution problem adopts following technical scheme:
The design feature of the utility model drill hole spray safety protection system is that the square chest that gathers dust is set, the gather dust front of square chest is openable skimming door, the two side is provided with air inlet pipe and the escape pipe that is communicated with the square chest that gathers dust respectively, in the square chest that gathers dust, be positioned at the place ahead of air inlet runner, baffle plate is set, and the top that is positioned at air inlet runner is provided with drencher; Air flow inlet at escape pipe is provided with filter screen.
The central axis that design feature of the present utility model also is air inlet pipe and escape pipe respectively with the upright square chest in the vertical direction angle at 45 that gathers dust.
Compared with the prior art, the utility model beneficial effect is embodied in:
1, the utility model can reduce the coal dust that the extraction pipeline sucks effectively when spray orifice, accomplishes coal dust and gas separating for several times.
2, the utility model can be caught and atomizes coal dust by spraying, reduces coal dust effectively and enters the extraction pipeline.
3, the utility model can prevent the extraction line clogging, realizes continuous extraction under the high negative pressure state.
The technical barrier that gas was taken away smoothly when 4, the utility model had solved spray orifice can realize that rig creeps into continuously and healthily, has improved drilling efficiency.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model master TV structure schematic diagram.
Number in the figure: 1 hinge, 2 drenchers, 3 filter screens, 4 carrying handgrips, 5 skimming doors, 6 air inlet pipe, 7 escape pipes, 8 baffle plates, 9 square chest that gathers dust.
Below pass through the specific embodiment, and the utility model is described in further detail in conjunction with the accompanying drawings
The specific embodiment
Referring to Fig. 1, Fig. 2, the present embodiment setting square chest 9 that gathers dust, the square chest 9 of gathering dust is positive to be openable skimming door 5, is connected with hinge 1 between skimming door 5 and the casing, when needing, directly opens skimming door 5 cleaning dirt slags, skimming door is answered the liner sealing mat, prevents gas leakage; The gather dust two side of square chest 9 is provided with air inlet pipe 6 and the escape pipe 7 that is communicated with the square chest 9 that gathers dust respectively, and the both sides external of the square chest that gathers dust is provided with carrying handle 4 respectively, so that move; In the square chest 9 that gathers dust, be positioned at the place ahead of air inlet runner, baffle plate 8 is set, coal dust because of be subjected to baffle plate 8 stop to fall; The top that is positioned at air inlet runner is provided with drencher 2, implements wet dust removal with drencher, makes the coal dust atomizing, no longer with gas air-flow associated movement; Air flow inlet at escape pipe 7 is provided with filter screen 3, constitutes the defence line, another road of coal dust in the gas channel.
In concrete the enforcement, the central axis of air inlet pipe 6 and escape pipe 7 respectively with the upright square chest 9 in the vertical directions angle at 45 that gathers dust.
Claims (2)
1, drill hole spray safety protection system gas purifier, it is characterized in that being provided with the square chest (9) that gathers dust, the described square chest that gathers dust (9) is positive to be openable skimming door (5), the two side is provided with air inlet pipe (6) and the escape pipe (7) that is communicated with the square chest that gathers dust (9) respectively, in the described square chest that gathers dust, be positioned at the place ahead of air inlet runner, baffle plate (8) is set, the top that is positioned at air inlet runner is provided with drencher (2); At the air flow inlet place of described escape pipe (7) filter screen (3) is set.
