Description
Technical field
The present invention relates to the online ash removal of dedusting filter cylinder, it is particularly suitable for for the deashing for easily firing dust purification filter core.
Background technology
Filtering type dedusting technology is efficient to the trapping of dust, is industrially widely used.With product of the dust on filtrate
Poly-, the running resistance of dust pelletizing system will increase, and need to carry out the regeneration that filtrate is realized in deashing processing to the dust of accumulation at this time.
Common purge mode has vibration cleaning, reverse gas cleaning and pulse jetting deashing etc..Wherein vibration cleaning simple structure
But low effort, damage filtrate, and flexible cloth-bag type is only applicable to without being suitable for rigid cartridge formula deduster；Reverse gas cleaning pair
The smaller and effect of filtrate damage is preferable, however complicated, can only influence continuing for dust pelletizing system by the way of off-line ash-clearing
Stable operation.The advantages that now widely used pulse jetting deashing has structure small, simple for process, and ash-removal effect is good.
However, pulse jetting deashing and other several purge modes all have same problem, i.e., taken off from filtrate after deashing
The dust that the part fallen is not lumpd, which only relies on gravity, cannot quickly fall into ash bucket, when the dust cloud of these high concentrations can be longer
Between be suspended in the babinet of deduster.Under the conditions of this, for inflammable and explosive dust, concentration is greatly likely located at
Within explosive range, there is serious explosion danger.
Invention content
In view of the deficiency of prior art, the present invention provides a kind of inward flow filtration-type filter core jet entrainment deashing device, can not only
The dust gathered on filtrate is effectively removed, and the dust that quickly deashing can fall off is sent into flue-dust retainer, greatly shortens deashing powder
Suspension time of the dirt in dust collector box body.

Fig. 2 is enlarged diagram at A in Fig. 1.
In figure：1 is pulse valve, and 2 be nozzle, and 3 be filter cylinder, and 4 be junction station, and 5 be card, and 6 be lock dirt window, and 7 be flue-dust retainer,
8 be crossbeam, and 9 be limiter I, and 10 be limiter II, and 11 be thistle board, and 12 be filter plate, and 13 be spring.
Specific implementation mode
Below in conjunction with attached drawing, the invention will be further described.
A kind of inward flow filtration-type filter core jet entrainment deashing device combined with Figure 1 and Figure 2, includes mainly pulse valve 1, nozzle 2, filter
Cylinder 3, flue-dust retainer 7, it is characterised in that further include junction station 4 and lock dirt window 6；3 bottom end opening of filter cylinder and the flower for being mounted on deduster
On plate 5, the top closure of filter cylinder 3 simultaneously connects nozzle 2 in end face center opening, and nozzle 2 connects pulse valve 1；3 inside of filter cylinder is fixed
Junction station 4 is installed, the opening face of junction station 4 nozzle 2 is simultaneously concentric with filter cylinder 3；The opening of filter cylinder 3 lower section sets flue-dust retainer 7, collection ash
Struggle against 7 closed upper parts and equipped with lock dirt window 6；It includes thistle board 11, filter plate 12, crossbeam 8 and spring 13 to lock dirt window 6, and thistle board 11 is adopted
It is mounted on the crossbeam 8 on lock dirt window 6 with the hinge with limiter I9, the filter plate 12 positioned at 11 lower section of thistle board, which uses, to be carried
The hinge of limiter II10 is mounted on crossbeam 8, and thistle board 11 and filter plate 12 are equipped with return spring 13.
Junction station 4 is circular in cross-section and the tapered from top to bottom hollow cylinder structure of cross-sectional area, close to nozzle 2
0.34 ~ 0.68 times of distance between a diameter of first junction station 4 of arrival end and nozzle 2 of first junction station 4.
The rotation angle of limiter I9 is limited to upward 90 ° to downward 90 °, and the rotation angle of limiter II10 is limited to water
It puts down to downward 90 °.
Flue-dust retainer 7 installs at least two lock dirt window 6.
In dedusting operation process, the dust in air-flow is trapped by the filter cylinder 3 as filter core element and is deposited on filter cylinder 3
Inner wall on.When needing deashing, pulse valve 1 is opened, and compressed air stream is blown by pulse valve 1 from nozzle 2, in 3 inside of filter cylinder
The heart generates the jet stream of high speed down.Due to the Involving velocity of jet stream, negative pressure, the dust of 3 inner wall of filter cylinder attachment are generated around jet stream
By suction function, falls off from filter cylinder 3 and carried secretly by jet stream.
Since jet stream dilating effect section can gradually increase, to prevent jet boundary from impacting 3 inner wall of filter cylinder, in jet stream route
Junction station 4 is set at upper suitable distance, such as straight in 12 cm of position inlet porting diameter, outlet for exporting 30cm apart from nozzle 2
The junction station 4 of diameter 4cm.Meanwhile when the jet stream of expansion is after junction station 4, the section of jet stream reduces again, to keep jet stream
Suction function, the dust for continuing to be attached near zone 3 inner wall of filter cylinder carry out volume suction.It similarly, can be in first junction station 4
Other junction stations 4 are set again below, similar can not only prevent jet boundary from directly impacting filter cylinder 3 to realize but also can extend
The effect of jet entrainment operating distance.
When carry secretly dust jet stream reach lock dirt window 6 corresponding with deashing filter cylinder 3 when, due to respectively with thistle board 11 and filter
The connected limiter I9 and limiter II10 of plate 12 has a rotation angle for rotating down 90 °, the effect of being hit of thistle board 11, together
When pushes filter plate 12, and unlatching, dust-contained airflow enter flue-dust retainer 7 downwards.At this point, the pressure rise in flue-dust retainer 7, non-deashing filter cylinder 3
The corresponding lock dirt window in position 6 is acted on by the pressure from flue-dust retainer 7 inside, corresponding thistle board 11 and the attempt of filter plate 12 all to
Upper unlatching.But since there is limiter I9 the rotation angle for being rotated up 90 °, limiter II10 not to have upward rotation angle
Degree, therefore, non-deashing position only have thistle board 11 and upwardly open realization 7 exhaust pressure relief of flue-dust retainer, and filter plate 12 remains stationary as guarantee powder
Dirt is intercepted not to be escaped.In brief, the deashing jet stream containing dust is downward simultaneously by thistle board 11 and filter plate 12 in deashing position
Unlatching gets enter into flue-dust retainer 7, and in non-deashing position by the interception of thistle board 11 upwardly opened with filter plate 12 to dust, most
It realizes eventually and the dust that deashing falls off is limited in flue-dust retainer 7.
After deashing jet stream, under the effect of spring 13, the thistle board 11 and filter plate 12 of deashing position are no longer by jet impulse
Power and return, the thistle board 11 of non-deashing position are no longer influenced by 7 internal pressure force effect of flue-dust retainer also return.It is distinguished and admirable in flue-dust retainer 7 at this time
It is static, dust settling.By above-mentioned action, the high concentrate dust that deashing generates is able to quickly control in flue-dust retainer 7, reduces
Suspension time of the dust in dust collector box body is to reduce explosion danger.
