Fig. 1 is the structural representation of specific embodiments of the invention one;
Fig. 2 is the structural representation of specific embodiments of the invention two.
Detailed description of the invention
The dust pelletizing system that the defeated ash of a kind of flue gas combines with filtration, see Fig. 1, Fig. 2: it comprises dirt source 1, fume trap cover 2, deduster 5, storage ash silo 10, dedusting fan 13, chimney 14, the upper outlet of chimney 14 is communicated with air, the top in dirt source 1 is provided with fume trap cover 2, deduster 5 comprises at least two bins 16, the flue dust that fume trap cover 2 is caught is assigned to each flue gas arm 4 by flue gas house steward 3, flue gas arm 4 passes into a side-entrance of the bottom of each bin 16 of corresponding deduster 5 respectively, pure qi (oxygen) house steward 7 is accessed by corresponding pure qi (oxygen) arm 6 in the top of each bin 16, the opposite side outlet of the bottom of each bin 16 accesses defeated grey house steward 9 by the defeated grey arm 8 of correspondence, flue gas mouth is entered at the middle part that defeated grey house steward 9 connects storage ash silo 10, the top pure qi (oxygen) outlet of storage ash silo 10 is circumscribed with fresh-air duct 11, dedusting fan 13 is furnished with in pure qi (oxygen) house steward 7, defeated grey blower fan 12 is provided with in fresh-air duct 11, the middle and upper part of storage ash silo 10 is provided with filtrating equipment of the filter bag 17, jetting deashing device 18, jetting deashing device 17 is positioned at the top of filtrating equipment of the filter bag 18.
Specific embodiment one: see Fig. 1, the end of pure qi (oxygen) house steward 7 is connected directly to the bottom air inlet of chimney 14, and fresh-air duct 11 connects the middle part of pure qi (oxygen) house steward 7, and dedusting fan 13 is positioned at the rear portion of the end of fresh-air duct 11.
Its operation principle is as follows: its workflow is as follows:
The flue gas that dirt source 1 is distributed or the dust cover 2 that is captured traps, flue gas after trapping or dust enter flue gas house steward 3, then the bin entering deduster 5 correspondence respectively by each flue gas arm 4 carries out dedusting, clean gas after each bin dedusting enters each pure qi (oxygen) arm 6 respectively, then enter pure qi (oxygen) house steward 7, finally send into chimney 9 by dedusting fan 8 through pure qi (oxygen) house steward 7 and discharge.
Deduster 5 deashing is undertaken by room in order.When deduster 5 starts deashing, first bin top pure qi (oxygen) port closing, its underpart exhanst gas outlet is opened, first bin stops filtration carrying out deashing, the dust that deashing gets off mixes with the flue gas entering this room, then discharged by this bottom, room exhanst gas outlet, enter the defeated grey arm 8 connecting this room, then enter storage ash silo 10 by defeated grey house steward 9.When the first bin deashing terminates to filter, when the second bin carries out deashing, the first bin top pure qi (oxygen) outlet is opened, and its underpart exhanst gas outlet is closed; Second bin top pure qi (oxygen) port closing, its underpart exhanst gas outlet is opened; Each bin carries out work successively respectively.Storage ash silo 10 is with filtrating equipment of the filter bag 17, and filter the flue gas mixed with dust entered, dust is delayed at filter bag superficial layer, and bin clean air enters the top clean room of storage ash silo 10 through filter bag, and the gas after up to standard is discharged.Be blocked in the dust on filter bag, after the process of jetting deashing device 18 jetting deashing, dust falls to concentrate and is stored in ash silo 10, regularly discharges.From the clean gas that storage ash silo 10 is discharged, pure qi (oxygen) house steward 7 is sent into by defeated grey blower fan 12 by fresh-air duct 11, mix with from the clean gas after other bin dedustings of deduster 5, mixed clean gas is finally sent into chimney 9 by dedusting fan 8 through pure qi (oxygen) house steward 7 and is discharged.
Specific embodiment two: see Fig. 2, pure qi (oxygen) house steward 7, fresh-air duct 11 are connected to the bottom air inlet of chimney 14 respectively, and flue gas house steward 3 is communicated to defeated grey house steward 9 by bypass pipe 15.
Its operation principle is as follows: the flue gas that dirt source 1 is distributed or the dust cover 2 that is captured traps, flue gas after trapping or dust enter flue gas house steward 3, then the bin that most flue gas or dust enter deduster 5 correspondence respectively by each flue gas arm 4 carries out dedusting, clean gas after each bin dedusting enters each pure qi (oxygen) arm 6 respectively, then enter pure qi (oxygen) house steward 7, finally send into chimney 9 by dedusting fan 8 through pure qi (oxygen) house steward 7 and discharge; Another part flue gas or dust successively enter storage ash silo 10 by bypass pipe 15, defeated grey house steward 9 and carry out dedusting, and the clean gas after dedusting is sent into chimney 9 by fresh-air duct 11 by defeated grey blower fan 12 and discharged.
Deduster 5 deashing is undertaken by room in order.When deduster 5 starts deashing, bypass pipe 15 cuts out.First bin top pure qi (oxygen) port closing, bypass pipe 15 cuts out, first bin bottom exhanst gas outlet is opened, first bin stops filtration carrying out deashing, the dust that deashing gets off mixes with the flue gas entering this room, then discharged by this bottom, room exhanst gas outlet, enter the defeated grey arm 8 connecting this room, then enter storage ash silo 10 by defeated grey house steward 9.When the first bin deashing terminates to filter, when the second bin carries out deashing, the first bin top pure qi (oxygen) outlet is opened, and its underpart exhanst gas outlet is closed; Second bin top pure qi (oxygen) port closing, its underpart exhanst gas outlet is opened; Each bin carries out work successively respectively.Storage ash silo 10 is with filtrating equipment of the filter bag 17, and filter the flue gas mixed with dust entered, dust is delayed at filter bag superficial layer, and clean air enters clean room through filter bag, and the gas after up to standard is discharged.Be blocked in the dust on filter bag, after the process of jetting deashing device 18 jetting deashing, dust falls to concentrate and is stored in ash silo 10, regularly discharges.From the clean gas that storage ash silo 10 is discharged, send into chimney 9 by fresh-air duct 11 by defeated grey blower fan 12 and discharge.After deduster 5 deashing terminates, bypass pipe 15 is opened.
