Description
Technical field
The present invention relates to control of coalmine gas field, specifically, removed the present invention relates to a kind of gas drainage pipeline negative pressure
Dirt device.
Background technology
Gas drainage under suction is to administer the maximally effective measure of gas, and either high-order drilling holes at the drilling yard extraction or upper corner pipe laying are taken out
Put, during gas drainage under suction, because gas drainage pipeline pipeline is long, negative pressure is big, the interior gas flow rate of pipe is big, easily causes gas
Coal petrography powder and a large amount of ponding occur in extraction pipeline, if cannot exclude in time, gas drainage under suction effect will be had a strong impact on.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of negative pressure dust removing device suitable for gas drainage pipeline.
In order to solve the above-mentioned technical problem, the technical solution adopted in the present invention is：Gas drainage pipeline depression dust-removing is filled
Put, including deduster body, negative pressure inlet pipe, depression outleting pipe and dewatering outlet, the negative pressure inlet pipe is fixed on deduster sheet
A side at the top of body, depression outleting pipe is fixed on another side of deduster bodies top, and the length of negative pressure inlet pipe is longer than
Depression outleting pipe, deduster body bottom portion connection water storehouse, water storehouse bottom connection dewatering outlet, the inside of the deduster body
Separate mesh and filter are set, and the separate mesh is arranged on above filter, negative pressure inlet pipe exports the bottom for putting in separate mesh, born
Extrude the top that tracheae is located at separate mesh.
It is preferred that, a side of the front panel of the deduster body sets water level observation hole.
It is preferred that, the front panel center of the deduster body, which is set, removes cinder notch.
Using technical scheme, following beneficial effect can be obtained：
The gas drainage pipeline negative pressure dust removing device of the present invention can enter gas in extraction pipeline, ponding, coal petrography powder three
Row is efficiently separated, and gas is pumped, and the sediment of ponding and the formation of coal petrography powder is discharged by osculum, thoroughly solves releasing pipe
The problem of coal petrography powder on road is gathered, it is ensured that the extraction of gas drainage pipeline, dedusting, slag dumping drainage effect, without termination of pumping just can and
When dedusting, deslagging, discharge water, ensure coal-face safety in production.
Brief description of the drawings
Brief description is made to the content expressed by each accompanying drawing of this specification and the mark in figure below：
Fig. 1 is structural representation of the invention；
Mark in above-mentioned figure is：1st, deduster body；2nd, negative pressure inlet pipe；3rd, depression outleting pipe；4th, separate mesh；5th, every
Net；6th, water storehouse；7th, dewatering outlet；8th, except cinder notch；9th, water level observation hole.
Embodiment
Below against accompanying drawing, by the description to embodiment, to the embodiment of the present invention such as involved each structure
Mutual alignment and annexation, the effect of each several part and operation principle between the shape of part, construction, each several part etc. are made further
Detailed description.
As shown in figure 1, this gas drainage pipeline negative pressure dust removing device includes deduster body 1, negative pressure inlet pipe 2, negative pressure
Escape pipe 3 and dewatering outlet 7, negative pressure inlet pipe 2 are fixed on a side at the top of deduster body 1, and depression outleting pipe 3, which is fixed on, to be removed
Another side at the top of dirt device body 1, the length of negative pressure inlet pipe 2 is longer than depression outleting pipe 3, the connection of the bottom of deduster body 1
Water storehouse 6, the bottom of water storehouse 6 connection dewatering outlet 7, the inside of deduster body 1 sets separate mesh 4 and filter 5, and separate mesh 4 is set
Put above filter 5, negative pressure inlet pipe 2 exports the bottom for putting in separate mesh 4, depression outleting pipe 3 is located at the upper of separate mesh 4
Portion；One side of the front panel of deduster body 1 sets water level observation hole 9, and the water level in deduster body 1 is observed at any time, is removed
The front panel center of dirt device body 1, which is set, removes cinder notch 8.
During extraction, the high-pressure water pipe on two sides of deduster is opened, the coal petrography powder that negative pressure is extracted out passes through height
The seizure of current is pressed, dust-laden atomized water is formed, when gas and water, dirt mixture with aerosol foam shape enter dedusting by negative pressure inlet pipe 2
After device, on the basis of mist inertia, the principle mutually collided using mist and filter 5, the mist on the surface of filter 5 is in diffusion
On gravity foundation, gas and water, dirt mixture speed diminish, and mist is gradually formed larger drop, drop is just from filter 5
Separate, autodeposition to bottom half, and gas density is small, swims in casing top, in the presence of negative pressure of suction, with
Depression outleting pipe 3 is pumped, and the debris after ponding and precipitation is discharged by dewatering outlet 7, and the larger solids of particle is then deposited on
On filter 5, staff is by opening except cinder notch 8 takes out sediment after accumulating to a certain extent.
Separate mesh 4 is a kind of high density separate mesh, change separate mesh can allow the pernicious gases such as gas by but can not allow and mix
The miscellaneous dust in gas passes through, and so the dust of gas surplus can be separated with pernicious gas, reach the purpose of dedusting.
The gas drainage pipeline negative pressure dust removing device of the present invention can make gas, ponding, the coal petrography powder three in extraction pipeline
Person is effectively separated, and gas is pumped, and the sediment of ponding and the formation of coal petrography powder is discharged by dewatering outlet 7, is thoroughly solved
The problem of coal petrography powder of extraction pipeline is gathered, it is ensured that the extraction of gas drainage pipeline, dedusting, slag dumping drainage effect, without termination of pumping
With regard to energy timely dedusting, deslagging, discharge water, ensure coal-face safety in production.
The present invention is exemplarily described above in conjunction with accompanying drawing, it is clear that the present invention is implemented not by aforesaid way
Limitation, as long as the improvement of the various unsubstantialities of inventive concept and technical scheme of the present invention progress is employed, or without changing
Enter and the design of the present invention and technical scheme are directly applied into other occasions, within protection scope of the present invention.
