Specific embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of coal bed gas gathering line powder purification apparatus, including filter cylinder 1, cyclone cylinder 2, gas bag
5th, injection tube 6, pulse valve 7, air pump 8 and isolating cylinder 10, the top of the cyclone cylinder 2 is cylindrical shape, and middle and upper part is truncated cone-shaped, in
Bottom is infundibulate, bottom connection ash bucket 13；Gas outlet 4 is provided with the top sidewall of the cyclone cylinder 2, on the wall of middle and upper part side
It is provided with air inlet 3；
The filter cylinder 1 is fixed on the top of the middle and upper part of cyclone cylinder 2, the central shaft of filter cylinder 1 and the central shaft one of cyclone cylinder 2
Cause, the internal diameter of filter cylinder 1 is consistent with the top ports diameter of cyclone cylinder 2；Isolating cylinder 10, the side wall of isolating cylinder 10 are cased with outside the filter cylinder 1
On be provided with helical form deflector 11；
One end of the injection tube 6 is provided with gas bag 5, and middle-end is provided with pulse valve 7 and the air pump being in parallel with pulse valve 7
8, the nose end of injection tube 6 is passed through in top sidewall to the cyclone cylinder 2 of cyclone cylinder 2, and the nose end of the injection tube 6 is provided with vertically
In injection tube 6 and spout nozzle 9 directed downwardly；In order to reduce in cyclone cylinder it is adherent on dust fly upward again, the cyclone cylinder 2
Structure is connected as one by cylindrical drum 2-1 between middle and upper part and middle and lower part, is provided with infundibulate in the middle and lower part of cyclone cylinder 2
Blanking conically shaped 12, the bottom of blanking conically shaped 12 is connected with ash bucket 13；The external diameter of the upper end of blanking conically shaped 12 cylinder is less than circle
The internal diameter of column casing 2-1 and form annular blanking channel 14.
In order that the dust on adherent in cyclone cylinder is successfully slid to ash bucket 13, fly again so as to be better protected from dust
Raise, the bevel altitude of the blanking conically shaped 12 is 1~3cm, and blanking conically shaped 12 is at least with the gap of the middle and lower part of cyclone cylinder 2
2cm。
In order to increase the wind speed of swirling eddy, strengthen the centrifugal force effect to dust granules, the helical form deflector 11
Lead angle be 10 °~25 °, horizontal range between the outward flange of helical form deflector 11 and isolating cylinder 10 is isolating cylinder 10
The 1/2~2/3 of horizontal range between outer wall and the inwall of cyclone cylinder 2.
In order to reduce local air flow resistance, the isolating cylinder 10 is the pyramidal structure that top is small, bottom is big, the taper knot
The cone angle of structure is 5 °~12 °.
When using, the coal bed gas for carrying dust enters cyclone cylinder 2 by air inlet 3, in the presence of centrifugal force and inertia force,
Air ring rotates around the wall of cyclone cylinder 2, and in the effect of deflector 11 and the outer wall of division board 10 and the inwall of cyclone cylinder 2
Lower spiral is descending；Dust-laden coal bed gas produces centrifugal force in rotary course, severe is overcome air-flow more than the dust granules of gas
Resistance shifts to the inwall of cyclone cylinder 2；Dust granules after being contacted with the inwall of cyclone cylinder 2, inertia force will be lost and in gravity and
It is adherent under the drive of rotating fluid to slide downwards.Outer formula structure of isolating cylinder 10 causes that the inside of the middle and upper part of cyclone cylinder 2 is empty
Between taper into from top to bottom, air-flow wind speed rotation downwards during become larger so that rotation decline air-flow it is more past
Lower produced centrifugal force is stronger, and dust granules are also better with the separating effect of coal bed gas, when swirling eddy reaches isolating cylinder 10
Adjacent bottom portions position after, turned back by down again with same direction of rotation and be upwardly into inside isolating cylinder 10.Air-flow is in the He of filter cylinder 1
Rise in space between isolating cylinder 10 and progress into filter cylinder 1, i.e., the air-flow between filter cylinder 1 and isolating cylinder 10 is in filter cylinder 1
The position of bottom is maximum, therefore in order to reduce local air flow resistance, the isolating cylinder 10 is using the taper knot that top is small, bottom is big
Structure.Unsegregated subparticle is intercepted at the outer of filter cylinder 1 with air-flow arrival filter cylinder 1 position under the effect of cyclone centrifugal power
Wall, clean air-flow is then discharged through filter cylinder 1 from gas outlet 4.
Under the influence of centrifugal force, the dust granules of air-flow are departed from from the adherent landing in the top of cyclone cylinder 2 and middle part, and by
It is cumulative many；Continue to rotate and begin to ramp up into inside isolating cylinder 10 after reaching bottom position due to the interior air-flow of cyclone cylinder 2,
That is the bottom position air turbulence of cyclone cylinder 2 is most severe, and the dust of adherent downslide is easily rolled by air-flow and flown upward again, therefore in order to
Prevent the dust of adherent downslide from being flown upward by volume suction again in the bottom of cyclone cylinder 2, the middle and lower part of the cyclone cylinder 2 is provided with annular blanking
Passage 14, when the dust glided from top is reached on the wall of cylindrical drum 2-1, will directly by annular blanking by Action of Gravity Field
Passage 14 enters ash bucket 13.
When the outer wall of filter cylinder 1 trapping dust reach it is a certain amount of after, it is necessary to when carrying out deashing to filter cylinder 1, booster air pump 8 goes out
The gas of the position of gas port 4 enters into injection tube 6 from the position of nozzle 9, then by entering gas bag 5 after the supercharging of air pump 8；Work as gas bag
When pressure in 5 reaches deashing requirement, starting impulse valve 7 is accumulated in the compressed air in gas bag 5 through injection tube 6 and pulse valve 7
Moment is sprayed from nozzle 9, and the air pulse of generation carries out blowback to filter cylinder 1, and the dust that the outer wall of filter cylinder 1 is trapped is blown off to ash
In bucket 13, so as to reach ash-removal effect.
