Bag opening, filter bag frame, hanging bag plate are positioned at cabinets cavity top, middle part, and filter bag is vertically disposed to middle part casing
In the inner chamber connected with lower part box.Described filter bag a size of Φ 130mm, filtrate is that PPS filter bag adds overlay film.
Further, described deashing mechanism includes pulse control instrument 9, differential pressure controller, pulse valve 5, spray
Blowpipe 7.Pulse control instrument is positioned at outside lower part box, connects differential pressure controller and pulse valve.Pulse valve position
Outside upper box body, pulse valve admission line arranging gas bag structure 4, pulse valve outlet connects injection tube.
Gas bag structure is positioned at the outside on casing top, middle part, and gas bag structure admission line arranges moisture trap 6, gas
Separator is positioned at the outside of middle part lower box.Injection tube is positioned at upper box body inner chamber bottom, and injection tube is led to
Cross Venturi tube 16 and filter bag inner space.
Further, described middle part casing is provided with maintenance door 8, and the outlet of described ash bucket is provided with star-shaped ash unloading valve
13, the connection between maintenance door and middle part casing, between star-shaped ash unloading valve and ash bucket outlet all uses asbestos pad
Compression seal connects, and improves the sealing of dust catcher device.
Further, welding procedure between described upper box body, middle part casing, lower part box, is used to connect,
Technological operation realizes simple.
Concrete removing dust and clearing ash process is as follows:
Former flue gas is entered filter chamber by air inlet 10, and particle dust big, heavy, due to the effect of gravity
Settling down, fall directly into ash bucket 12, the gas containing relatively fine dust is up, when by filter bag 14,
Airflow direction ecto-entad, dust is delayed at filter bag 14 outer surface, makes gas be purified, through filter bag
Neat stress after 14 purifications, discharges through exhaust outlet 11.
During deduster dust removal by filtration, by the detection poor to outside pressure in filter bag in filter chamber 14,

Unbalanced pulse valve 5, allows compressed air into injection tube 7 and sprays into filter bag 14 inner chamber, gas by Venturi tube 16
From inside to outside, under the effect of back draught, the dust investing filter bag 14 outer surface departs from rapidly filter to flow path direction
Bag 14 falls into ash bucket 12, it is achieved the jetting deashing to filter bag 14.Filter bag 14 is sprayed by injection tube 7 by row
Blowing-out ash, the filter bag 14 now not carrying out jetting deashing is still normally carried out dust removal by filtration, and jetting deashing process is not
Affect the properly functioning of deduster.
Further, during jetting deashing, first compressed air carries out, through moisture trap 6, place of anhydrating
Enter gas bag structure 4 after reason, then enter injection tube 7 through pulse valve 5.Moisture trap 6 can remove compression
Steam in air, prevents containing steam in the compressed air of entrance injection tube 7, and then affects filter bag 14
Dust removing effects.Gas bag structure 4 can store compressed air, provides enough compressed airs for jetting deashing process
And air pressure.Whole process is carried out automatically, and the winding-up time of pulse valve 5 and jetting pressure are by Pulse Width Control
Instrument 9 adjusts, and efficiency of dust collection is high, can reach optimal dust removing effects, has saved compressed air simultaneously.Finally,
Dust in ash bucket 12 is discharged through star-shaped ash unloading valve 13.
