Detailed description of the invention
In the present invention, identical appended drawing reference always shows identical feature, in which:
Fig. 1 is the utility model bag filter structure chart.
Description of symbols:
1, air accumulator；2, clean room；3, electromagnetic impulse valve；4, annular space injector；5, purified gas outlet；6, filter bag；7,
Filter screen；8, cabinet；9, ash bucket；10, unloading valve；11, bracket；12, dusty gas entrance；Tracheae 13；Jet pipe 14.
Specific embodiment
The technical solution of the utility model is further illustrated with reference to the accompanying drawings and examples.
In conjunction with Fig. 1, a kind of bag filter, including it is air accumulator 1, clean room 2, electromagnetic impulse valve 3, annular space injector 4, net
Change gas vent 5, filter bag 6, filter screen 7, cabinet 8, ash bucket 9, unloading valve 10, bracket 11, dusty gas entrance 12, tracheae 13,
Jet pipe 14.
Cabinet 8 is mounted on bracket 11, and cabinet 8 is divided into 9 two parts of toilet 2 and ash bucket, between toilet 2 and ash bucket 9
Filter screen 7 is installed.The top of ash bucket 9 offers dusty gas entrance 12, and the lower section of ash bucket 9 is equipped with unloading valve 10.Tracheae
13 are mounted in toilet 2, and 13 one end of tracheae is connected with air accumulator 1, and filter bag 6 is connected by electromagnetic impulse valve 3 with tracheae 13, electricity
Magnetic field impulse valve 3 is also connected with annular space injector 4.Purified gas outlet 5 is offered in toilet 2.
Tracheae 13 is metal hose, and metal hose passes through flange respectively and is connected with air accumulator, electromagnetic impulse valve.Filter bag 6
Worry cage is inside installed.Filter screen 7 can be stainless steel filter screen.Bracket 11 is stainless steel stent.In order to improve the filtering of gas
Effect is equipped with multiple jet pipes 14 in toilet 2.
When it is implemented, the negative pressure that is generated by air-introduced machine of the process flow of bag filter is by sludge after incinerator is handled
Generated flue gas enters bag filter after semi-dry desulphurization tower desulfurization and is dusted processing, discharges after up to standard.Ash-laden gas
Body enters pocket by dusty gas entrance, and the thicker grit of a part is fallen into ash bucket by inertia or gravitational settling, remaining major part
Grit rises after sock filtration with air-flow, and grit is trapped in the outside of filter bag, and purified gas inside filter bag by entering
Clean room is then discharged from purified gas outlet, atmosphere is discharged into air-introduced machine and chimney, to achieve the purpose that dedusting.
When deduster inlet and outlet resistance changes, and reaches certain differential pressure value, dust-removing control device issues deashing to electromagnetic impulse valve
Instruction, with the unlatching of impulse electromagnetic valve, deashing air-flow moment is sent into bag with impulse form by flue gas adverse current direction, makes filter bag
Strong shake is generated, the dust being adsorbed on the outside of filter bag is shaken off, achievees the purpose that deashing.
In bag filter use process failure main reasons is that:
1, the pulse gas transmission connecting pipe road of bag filter it is shorter do not buffer leeway in bag filter soot blowing cannot
Reaction force caused by compressed air when release soot blowing in time, and the connection type crystallized ability of rubber hose and anchor ear is not
Foot makes pulse gas transmission connecting pipe road generate fierce shake in soot blowing and rubber gas pipeline is caused to fall off, it is made to lose deashing
Effect.
2, bag filter is run under subnormal ambient, and after pulse gas transmission connecting pipe road falls off, atmosphere is then inhaled
Enter in bag filter, forming flue gas system negative pressure reduces, and to keep the operating pressure in incinerator, only increases air-introduced machine
Power, causing cloth bag to run under unstable high negative pressure keeps cloth bag stress seriously uneven.
3, when incinerator is stopped transport, the air being inhaled into bag filter can not be drained, when flue-gas temperature drops to
When dew point and after the external gas haptoreaction entered, and acid is generated, not only causes heavy corrosion to also add cloth bag
Corrosion to the other components in bag filter inside makes cloth bag lose its original mechanical strength, eventually leads to the powder in flue gas
Dirt direct emission, pollutes the environment.
In order to avoid the generation of above-mentioned failure, in the case where not changing its original process flow, to former pulse appendix
Road connection type optimizes: overhauling for convenience, below the former inspection platform at 2m, then to have built a width again larger
Inspection platform and stair；Air accumulator is moved down into 1.5m, is placed on newly-built inspection platform；By former rubber hose and anchor ear
Connection type is changed to be reached by the connection type of flanged (FLGD) metal hose and increased intensity and release reaction force；Jet pipe is prolonged
Rest after 0.5 meter of length is supplied former jet pipe to metal hose and is transformed between metal hose.
The purpose of optimization is to improve the operation stability of bag filter, guarantee continuous production, mitigate maintenance intensity, subtract
Few pollution to environment.
In conclusion using the technical solution of the utility model, the utility model embodiment bag filter has and removes
The feature that dirt is high-efficient, structure is simple, convenient operating maintenance, cost and operating cost are low；The utility model bag filter, subtracts
Light service work intensity reduces maintenance expense, reduces the pollution to environment, mentions for the continuous operation of drying and incineration system
Reliable guarantee is supplied；Can frequently perforate to avoid chimney over-emitting black exhaust, cloth bag, repeatedly maintenance, fluctuation of service the problems such as, effectively
Ground improves its economic benefit and social benefit.
