Using the utility model of technical solution as above, have the advantages that compared with the existing technology:
The utility model overcomes wet dedusting desulfurization water first is that water consumption is few using dry method dust desulfurization to flue gas
The problem of amount is big, be easy to cause secondary pollution；Second is that desulfurizing agent can restore regeneration, use cost is low, and enterprise is easy to connect
By easy to promote；Third is that dry method dust desulfurization is small to equipment corrosion, maintenance cost is low, long service life.
Cause what air-introduced machine can not be completely isolated to ask in addition, the utility model solves air-introduced machine exit flue gas and alters
Topic, guarantees the safety of service work.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is utility model flue-gas dust-removing and desulfurization apparatus structure schematic diagram.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Shown in Figure 1, the utility model provides flue-gas dust-removing and desulfurization device, including sequentially connected air inlet pipe 1, dedusting
Device 2, flue, air-introduced machine, annular air-guide section 5 and desulfurization cylinder 6, the flue include the first flue 21 and the second flue 22, institute
Stating air-introduced machine includes the first air-introduced machine 31 and the second air-introduced machine 32, first flue setting deduster and the first air-introduced machine it
Between, second flue is arranged between deduster and the second air-introduced machine, sets between first air-introduced machine and annular air-guide section
It is equipped with the first smoke guide pipe 41, is provided with the second smoke guide pipe 42 between second air-introduced machine and annular air-guide section, the annular is led
Gas section is arranged around desulfurization barrel outer surface, is uniformly distributed on the annular air-guide section and is provided with and communicated with multiple nozzles 51, described
Multiple nozzles 51 are connected to desulfurization cylinder.
As the utility model specific embodiment, first entrance isolating door 211, institute are provided on first flue
It states and is provided with second entrance isolating door 212 on the second flue, be provided with first outlet isolating door 411 in first smoke guide pipe,
