Description
Technical field
The utility model is related to the online ash removal of dedusting filter cylinder, is particularly suitable for use in for easily firing the clear of dust purification filter core
Ash.
Background technology
Trapping of the filtering type dedusting technology to dust is efficient, is industrially widely used.With product of the dust on filtrate
Poly-, the running resistance of dust pelletizing system can increase, and now need to carry out the dust of accumulation the regeneration that filtrate is realized in deashing processing.
Conventional 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 suitable for rigid cartridge formula deduster；Reverse gas cleaning pair
Filtrate damage is smaller and effect is preferable, but complicated, can only influence continuing for dust pelletizing system by the way of off-line ash-clearing
Stable operation.Now widely used pulse jetting deashing, small with structure, technique is simple, the advantages of ash-removal effect is good.
Taken off however, pulse jetting deashing and other several purge modes are all present after same problem, i.e. deashing from filtrate
The dust that the part fallen is not lumpd, which only relies on Action of Gravity Field, can not quickly fall into ash bucket, when the dust cloud of these high concentrations can be longer
Between be suspended in the casing of deduster.Under the conditions of this, for inflammable and explosive dust, its concentration is greatly likely located at
Within explosive range, with serious explosion danger.
Utility model content
In view of the deficiency of prior art, the utility model provides a kind of inward flow filtration-type filter core jet entrainment deashing device, not only

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.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to Fig. 1 and Fig. 2, a kind of inward flow filtration-type filter core jet entrainment deashing device mainly includes pulse valve 1, nozzle 2, filter
Cylinder 3, flue-dust retainer 7, it is characterised in that also including junction station 4 and lock dirt window 6；The bottom end opening of filter cylinder 3 and the flower for being arranged on deduster
On plate 5, the top closure of filter cylinder 3 simultaneously connects nozzle 2, the connection pulse valve 1 of nozzle 2 in end face center opening；The inside of filter cylinder 3 is fixed
Junction station 4 is installed, junction station 4 is open just to nozzle 2 and 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 provided with lock dirt window 6；Locking dirt window 6 includes thistle board 11, filter plate 12, crossbeam 8 and spring 13, and thistle board 11 is adopted
It is arranged on the hinge with limiter I9 on the crossbeam 8 on lock dirt window 6, the filter plate 12 positioned at the lower section of thistle board 11, which is used, to be carried
Limiter II10 hinge is arranged 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 cross-sectional area hollow cylinder structure tapered from top to bottom, 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 limiter I9 anglec of rotation is defined to upward 90 ° to downward 90 °, and the limiter II10 anglec of rotation is defined to water
Put 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
Inwall on.When needing deashing, pulse valve 1 is opened, and compressed air stream is blown by pulse valve 1 from nozzle 2, in the inside of filter cylinder 3
The heart produces jet at a high speed down.Due to the Involving velocity of jet, negative pressure, the dust of the inwall of filter cylinder 3 attachment are produced around jet
By suction function, come off and carried secretly by jet from filter cylinder 3.
Because jet dilating effect section can gradually increase, to prevent jet boundary from impacting the inwall of filter cylinder 3, in jet route
Junction station 4 is set at upper suitable distance, such as the 30cm cm of position inlet porting diameter 12 is being exported apart from nozzle 2, is exporting straight
Footpath 4cm junction station 4.Meanwhile, when the jet of expansion is after junction station 4, the section of jet reduces again, to keep jet
Suction function, the dust for continuing to be attached near zone the inwall of filter cylinder 3 carries out volume suction.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 but also can extend to realize
The effect of jet entrainment operating distance.
When carry secretly dust jet reach it is corresponding with deashing filter cylinder 3 lock dirt window 6 when, due to respectively with thistle board 11 and filter
The connected limiter I9 and limiter II10 of plate 12 has an anglec of rotation for rotating down 90 °, the effect of being hit of thistle board 11, together
When promote filter plate 12 downwards open, dust-contained airflow enter flue-dust retainer 7.Now, the pressure rise in flue-dust retainer 7, non-deashing filter cylinder 3
The corresponding lock dirt window 6 in position by the pressure effect from flue-dust retainer 7 inside, corresponding thistle board 11 and filter plate 12 attempt all to
It is upper to open.But it is due to that limiter I9 has the anglec of rotation for being rotated up 90 °, limiter II10 does not have the upward anglec of rotation
Degree, therefore, non-deashing position only thistle board 11, which is upwardly opened, realizes the exhaust pressure relief of flue-dust retainer 7, and filter plate 12 remains stationary as guarantee powder
Dirt is intercepted not to be escaped.In brief, the deashing jet containing dust is simultaneously downward by thistle board 11 and filter plate 12 in deashing position
Unlatching gets enter into flue-dust retainer 7, and in the interception that upwardly opens with filter plate 12 to dust of the non-deashing position by thistle board 11, most
The dust that deashing comes off is realized eventually is limited in flue-dust retainer 7.
After deashing jet terminates, 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 the internal pressure power of flue-dust retainer 7 effect also return.It is now distinguished and admirable in flue-dust retainer 7
It is static, dust settling.By above-mentioned action, the high concentrate dust that deashing is produced is able to quickly control in flue-dust retainer 7, reduces
Suspension time of the dust in dust collector box body is so as to reduce explosion danger.
