Body, lower box is divided into multiple dirt pocket, and lower box side arranges air inlet 4, is provided with baffle plate 5, upper box at air inlet 4
Side arranges air outlet 6, is vertically installed with multiple cloth bag 7 at lower box interior parallel, and cloth bag 7 upper end open is arranged on card 2
On, outside each cloth bag 7, it being respectively provided with marsupial cage 8, injection tube 1 downside is provided with multiple puff prot, each puff prot divides
Not corresponding cloth bag 7 upper end open, the internal diameter of described injection tube 1 is gradually reduced along air circulating direction, at each puff prot
Being additionally provided with guiding air jet pipe 14, the internal diameter of described guiding air jet pipe 14 is inverted cone, guides air jet pipe 14 under stream pressure
Extending downwardly from injection tube 1, injection tube 1 connects the second compressed air bag 12 by pulse valve, is additionally provided with the first compressed air bag
11, between first compressed air bag 11 and the second compressed air bag 12, it is provided with compressed air except water oil removal filter 13.
Preferably, described compressed air is disposed with oil water separator, efficient degreasing except water oil removal filter 13 is internal
Device, greasy dirt accurate filter, micro-greasy dirt accurate filter, dust filter unit and high accuracy accurate filter；Described cloth bag 7 is tool
Having the cloth bag of antistatic performance, including antistatic base fabric and be arranged on the teflon coatings outside it, described bag cage 8 is spring bone
Frame bag cage or organosilicon dedusting skeleton bag cage, be additionally provided with one layer of electrostatic prevention film outside bag cage.
Further, being arranged above assisting soot cleaning system at card 2, described auxiliary soot cleaning system includes multiple sound wave
Dust remover or multiple mechanical vibration deashing device 9, be arranged above a circle cleaning brush 10, described cleaning at each bag of cage 8
Brush 10 can move up and down along bag cage 8, and the adjustable angle of described cleaning brush 10, and adjusting angle is the footpath relative to bag cage 8
Rotate in the range of-30 °-30 ° of face.
The soot cleaning system for kiln tail Low-Pressure Pulse Bag Filter of the present invention, blowing pipe structure is arranged rationally, and
The air of winding-up is through processing, it is to avoid moisture content and oil point, pollutes cloth bag and bag cage, causes being stained with ash, injection tube internal diameter gradual change, protects
Demonstrate,prove the air pressure in whole pipeline identical, it is ensured that the efficiency of cloth bag deashing.
Cloth bag and bag cage are disposed as antistatic, to avoid producing Electrostatic Absorption dust, bring obstruction for deashing.
In bag cage upper end, Venturi tube is installed, the guiding air jet pipe stretched out can apart from Venturi tube closer to, be directed at Venturi tube
Opening part jet, reduces the compressed-air actuated pressure loss, and guides air jet pipe and do not have the pressure of gas when injection tube does not works

The soot cleaning system for kiln tail Low-Pressure Pulse Bag Filter of the present invention, arranges soot cleaning system and auxiliary deashing system
System, promote cleaning efficiency, and box house set up multiple dirt pocket separately, can cooperate work and deashing work, cloth bag with
The setting of bag cage also promotes filter efficiency.Air inlet arranges baffle plate, tentatively stops the flue dust come in and drops, bigger
Dust granule can drop in ash bucket under the stop of baffle plate, and lighter flue dust can enter follow-up bag-type dust, and baffle plate is permissible
Arranging certain angle, effect is more preferable.
The soot cleaning system for kiln tail Low-Pressure Pulse Bag Filter of the present invention, cleaning efficiency is high, processes gas capacity
Greatly, stable performance, life-span of the filter bag is long, easy to operate, ensure while dust removing effects can service life of extension device.
During the work of kiln tail Low-Pressure Pulse Bag Filter, particle dust is sent into by dusty gas by air inlet, removing dust room
Ash bucket, initially strikes the baffle plate in the middle of air inlet, and air-flow just turns to inflow ash bucket, and air velocity slows down simultaneously, owing to inertia is made
With, making crude particle dust in gas flow directly into ash bucket, play the effect gathered dust in advance, the air-flow entering ash bucket is rolled over subsequently and is upwards led to
Cross Bag filter, so that oarse-grained dust falls directly into the less dust of hopper bottom and is upwardly into cloth bag with air-flow turnover
Filtering, and be delayed at filter bag outer surface, the flue gas purified enters in bag, and enters air outlet through bag mouth and upper box, by
Air outlet is discharged.Along with that filters is constantly carried out, the dust of cloth bag outer surface is continuously increased, and equipment resistance rises therewith, when setting
When standby resistance rises to certain value, deashing operation should be carried out, remove the dust stratification on cloth bag surface.
During soot cleaning system work, the lifting valve that first dirt pocket needing deashing promotes system cuts out, by filtered airflow
Blocking, then electromagnetic impulse valve is opened, and connects air compressor machine outside the first empty compressed package, compressed air with time of extremely short rush upper
Expand rapidly in casing, pour in cloth bag through the Venturi tube of cloth bag opening part, make cloth bag dilatancy produce vibration, and at reverse gas
Under the effect that stream washes away, the dust being attached on cloth bag outer surface is stripped and falls in ash bucket, carries out subsequently assisting deashing, opens
Acoustic wave soot blower or mechanical vibration deashing device, carry out vibration cleaning to each cloth bag and bag cage, and utilize cleaning brush simultaneously
Cleaning cloth bag and the outside of bag cage, or after waiting vibration cleaning to complete, recycling cleaning brush clears up cloth bag and the outside of bag cage.Clearly
After ash, electromagnetic impulse valve is closed, and promotes valve and opens, and this dirt pocket recovers again filtration condition.The each dirt pocket of deashing enters successively
OK, start to deashing next time to start to be a cleaning cycle from the first Room deashing, be trapped down with deashing work through filtering
The dust come falls into ash bucket, then is concentrated discharge by the Star-like unloader of ash quarrel.
