Abstract
The present invention discloses the device of a kind of efficient removal flue gas of refuse burning dust and dioxin, belong to the dedusting of burning power plant and except dioxin technical field, it, which is disclosed, increases oblique deflector with holes and bluff body to existing bag filter inlet, two bag filters are connected simultaneously, export injection active carbon in level-one bag filter.The present invention improves bag filter interior flow field uniformity and reduces impact of the air-flow to filter bag, extends cloth bag service life；Simultaneously because flying dust and the part dioxin being attached on flying dust are removed by level-one cloth bag, remaining dioxin then passes through level-one cloth bag and mixes with active carbon to be removed by second level cloth bag, what is unloaded when from second level cloth bag deashing is the clean active carbon of comparison, the recycling of active carbon may be implemented, while greatly improving the removal efficiency of dioxin.
Description
Technical field:
The invention belongs to garbage-incineration smoke purifying field, is related to bag filter, specifically a kind of efficient removal
The system of flue gas of refuse burning dust and dioxin.
Background technique:
Currently, it is most widely " active carbon injection+bag-type dust that the dioxin in removing burning power plant flue gas, which uses,
Device " technology, although this method has preferable removal effect to dioxin, active carbon consumption is larger, operating cost is high,
And due to dioxin, some is adsorbed on fly ash granule, there are flue gases in the form of gaseous suspension for another part
In because in flue gas flying dust and heavy metal etc. influence, active carbon is less desirable to the dioxin adsorption effect of gaseous suspension.
Meanwhile existing bag filter inlet is there are apparent jet effect, it is uneven that this will lead to deduster interior air-flow, to filter bag
Greater impact is generated, efficiency of dust collection is reduced, shortens life-span of the filter bag.
Summary of the invention:
The object of the present invention is to provide the devices of a kind of efficient removal flue gas of refuse burning dust and dioxin, can be improved
Dioxin removal effect reduces activated carbon dosage, reduces operating cost, extends life of bag filter.
Compressed air cylinder (1) of the present invention in the prior art, injection tube (2), solenoid valve (3) seal card (4), cabinet
(6) and compressed air cylinder (1.1), injection tube (2.2), solenoid valve (3.3) seal card (4.4), cabinet (6.6), this hair
It is bright that especially two bag filters (13 and 14) are connected in the form of firsts and seconds, it is in firsts and seconds bag-type dust
Deflector (7 and 7.7) are arranged behind device gas inlet channel, and activity is set at level-one bag filter (13) outlet (11)
Charcoal injection apparatus (12).
The above deflector of the present invention is in tilted layout.
Through-hole is had in deflector of the present invention.
The height of the above deflector of the present invention is gradually increased along flow of flue gas direction.
Radius on deflector of the present invention with bluff body gradually becomes smaller along flow of flue gas direction.
Compared with prior art, the invention adopts the above technical scheme following technical effect:
1, at the smoke inlet behind deflector is set, keep the air flow method in bag filter more uniform, raising removes
Dirt efficiency reduces jet stream and washes away to filter bag, extends cloth bag service life.
2, firsts and seconds bag filter is connected, sprays active carbon in level-one bag filter smoke outlet, flies
Ash and the solid phase dioxin being attached to above flying dust and heavy metal are removed by level-one cloth bag, and gas phase dioxin then passes through level-one cloth bag
It is mixed with active carbon, the active carbon of level-one cloth bag outlet injection can more effectively be inhaled under the interference of the particulate matters such as no flying dust
Attached gas phase dioxin greatly improves the removal efficiency of dioxin and heavy metal, reduces activated carbon dosage.Simultaneously as particulate matter
Deng being removed by level-one cloth bag, what when second level cloth bag deashing was unloaded is more clean active carbon, and the weight of active carbon may be implemented
It is multiple to utilize, reduce operating cost.
A kind of " the waste incinerator both ends formula flue gas purification system " of the prior art is a flue gas purifying technique, it is used
Two-stage bag-type dust among there are also SCR, semidry method, active carbon flue gas purifying techniques.And without appointing between two-stage of the invention
What his technique, removing is pollutant of the same race, and structure is also different at cloth bag smoke inlet.
Detailed description of the invention:
Fig. 1 shows general structure schematic diagrams of the invention.
Specific embodiment:
According to Fig. 1, compressed air cylinder 1 of the present invention in the prior art, injection tube 2, solenoid valve 3 seal card 4,
Cabinet 6 and compressed air cylinder 1.1, injection tube 2.2, solenoid valve 3.3 seal card 4.4, on the basis of cabinet 6.6, this hair
It is bright that especially two bag filters 13 and 14 are connected in the form of firsts and seconds, deduster is arranged in level-one 13 and second level
Even distribution device deflector 7 and 7.7 behind 13.13 gas inlet channels 8 and 8.8 is set at the outlet of level-one bag filter 13 11
Set active carbon injection apparatus 12.
The above deflector of the present invention is in tilted layout.Through-hole is had in deflector, the height of deflector is along flow of flue gas direction
It gradually increases, the radius on deflector with bluff body is gradually small along flow of flue gas direction.
Basic functional principle and workflow of the invention:
Flue gas of refuse burning enters from 13 gas inlet flue 8 of level-one bag filter, passes through filter bag by flow apron 7
5 flow from bottom to top, and particulate matter filters and formed dust layer by filter bag 5, as time increases, the powder of 5 surface layer of filter bag attachment
Dirt particle is more and more, needs to carry out deashing to filter bag at this time.Using pulse dust cleaning system by periodically or constant DP control into
Row deashing, when deashing work carries out, particle falls off from filter bag surface layer, will be in ash bucket 10 by unloading valve 9 into ash bucket 10
Flying dust be discharged to ash-transmission system.Dust in flue gas and the dioxin and heavy metal being adsorbed on above dust are removed by level-one cloth bag
Dirt device 13 is removed, and filtered clean gas is sufficiently mixed by 13 exhanst gas outlet channel 11 of level-one bag filter and active carbon
It closes, enters second level bag filter 13.13 from 13.13 gas inlet channel 8.8 of second level bag filter, by same principle
By active carbon particle and it is adsorbed on dioxin and heavy metal removing above.Due to dust and it is attached to dioxin above and again
Metal is removed by level-one bag filter 13, and the active carbon of the outlet of level-one bag filter 13 injection is in particles such as no flying dusts
Dioxin and heavy metal can be more effectively adsorbed under the interference of object, are greatly improved the removal efficiency of dioxin and heavy metal, are subtracted
Few activated carbon dosage.Simultaneously as particulate matter etc. is removed by level-one bag filter 13, second level bag filter 13.13 is clear
What is unloaded when grey is the clean active carbon of comparison, and active carbon can reuse, and reduces operating cost.
