Height, and according in ash bucket 5 dust accumulation height send corresponding signal；Controller receives the signal that detector is sent,
Logical close of stop valve in dusty gas import is controlled.Specific operating process is：When detector is detected in ash bucket 5
Dust accumulation height not less than alert locations, then the stop valve of controller control dusty gas import is open-minded；When detector inspection
The dust accumulation measured in ash bucket 5 highly exceedes alert locations, then the stop valve of controller control dusty gas import is closed,
Grey processing is unloaded to stop dedusting work progress.In specific dedusting work, the possible remote ash bucket 5 of staff's meeting, in order to
Staff can be notified unload the report for also including being connected with detector in ash manipulation, high density bag-type dust collector in time
Alarm device, the dust accumulation that warning device reception detector is sent highly is more than the signal of warning height, and according to the letter
Number alarmed, to remind staff to carry out unloading ash manipulation accordingly in time.
Porous plate 12 is located between filter chamber 11 and first chamber 13, and the upper end installed in filter chamber 11, porous plate 12 is set
There are multiple through holes, each through hole of porous plate 12 extends downwardly a filter bag 2, and blast pipe 3 is parallel located at the side of filter bag 2, exhaust
The port of pipe 3 is extended at porous plate 12, the axially distributed side opening having towards filter bag 2 of blast pipe 3, each side of filter bag 2, mistake
The air of filter chamber 11 can only be by entering first chamber 13, the air permeable blast pipe 3 of filter chamber 11, into filter bag after filter bag 2
2, and into first chamber 13 after the interior through hole upwardly through porous plate 12 of filter bag 2, and the side of each filter bag 2 is arranged symmetrically two
Blast pipe 3, blast pipe 3 is connected with ash bucket 5, and high density bag-type dust collector is entered in dedusting operation process by air inlet 9
Dusty gas sprays into filter chamber 11 upwards from each blast pipe 3, now, according to fluid mechanics principle, and the air pressure in blast pipe 3 is obvious
Less than the air pressure near filter bag 2, so the dust on the surface of filter bag 2 will be inhaled into blast pipe 3, and filter chamber 11 is sprayed at again
Interior, a part drops downward into ash bucket 5, and a part is inhaled into blast pipe 3 and is sprayed on filter chamber 11 again again, until reaching flat
Weighing apparatus；And the surface of filter bag 2 then remains less dust, so as to keep higher filter efficiency, deduster is set continuously to enter
Row dedusting operation；Traditional injection system is eliminated, cost is also reduced.
In addition, also including cloth bag aids in deashing device, cloth bag auxiliary deashing device is in first chamber 13, cloth bag auxiliary
Deashing device includes acoustic wave soot blower 14 and nozzle 15, and acoustic wave soot blower 14 is in first chamber 13, and one end of nozzle 15 is set
In the side of acoustic wave soot blower 14, the other end of nozzle 15 is connected with compressed air hose, and acoustic wave soot blower 14 is matched somebody with somebody with nozzle 15
Conjunction is used, and the quantity of acoustic wave soot blower 14 and nozzle 15 is several, and the happening part of each acoustic wave soot blower 14 correspond to
One filter bag 2, can start acoustic wave soot blower 14, due to the upper end of each filter bag 2 during carrying out dedusting by filter bag 2
Provided with acoustic wave soot blower 14, each filter bag 2 can realize independent online ash removal, and acoustic wave soot blower 14 is superpower to filter bag 2 one
Sound wave, successful distance of the superpower sound wave to one vibration in surface of filter bag 2, helps dust to fall into ash bucket, in the process of deashing
In can be with start by set date air compressor, compressed air by compressed air adapter can be transported to some sprays by air compressor
Realized at mouth 15 and acoustic wave soot blower 14 is blown, prevent the dust stratification of acoustic wave soot blower 14 from blocking, it is ensured that acoustic wave soot blower
14 using effect, is so ensured that in dedusting operation, does not have the ash removed when blast pipe 3 is carried out into dedusting on filter bag 2
Dirt application acoustic wave soot blower 14 carries out secondary deashing so that ash-laden gas can obtain further deashing so that the cigarette of discharge
Gas reaches discharge standard, can reach minimum discharge, and the flue gas after filtering is more cleaned, and reaches the emission request of environmental protection.
Further optimization, in addition to one by the dividing plate 10 that 11 points of filter chamber is at least two mutually isolated dedusting areas,
Each dedusting area is connected by switch valve 6 with ash bucket 5, and in high density bag-type dust collector, dusty gas is entered in ash bucket 5
Entered later by each switch valve 6 in corresponding dedusting area, dusty gas is filtered by the filter bag 2 in dedusting area,
For the flowing velocity of dusty gas being lowered into dedusting area, to reduce the impact to filter bag 2, ash bucket 5 with it is each
The position that dedusting area is connected is respectively provided with horn-like air inlet, and one end that the cross-sectional area of the horn-like air inlet is larger is located at far
From one end of ash bucket 5, by the expansion to air inlet open area, the flow velocity of dusty gas is reduced.High density bag-type dust collector exists
