Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described, and example is served only for explaining the present invention, is not intended to limit
Determine the scope of the present invention.
It is that a kind of vortex in the present invention restrains dedusting demister 100, including housing 10, poly- liquid as shown in Fig. 1~Fig. 2
Case 20, flusher 30 and multiple dedusting demisting monotubulars 40.The housing 10 be vertically arranged and it is interior be provided with a dedusting demisting cavity,
The liquid collector 20 is arranged at the lower section of the housing 10, and the liquid collector 20 is an internal diameter diminishing taper from top to bottom
Body, the flusher 30 is arranged at the dedusting demisting cavity upper strata, and the flusher 30 includes multiple shower nozzles 31, multiple
The dedusting demisting monotubular 40 is arranged in the dedusting demisting cavity, and each top of the dedusting demisting monotubular 40 is respectively provided with
There is a shower nozzle 31, multiple dedusting demisting monotubulars 40 are in matrix arranged adjacent, and the side wall of the housing 10 is additionally provided with one and is located at
Air inlet 11 between the liquid collector 20 and multiple dedusting demisting monotubulars 40, the top of the housing 10 is provided with an outlet
Mouth 12.
As the dedusting demisting main body of whole device, it is disposed with from top to bottom in each described dedusting demisting monotubular 40
Primary separator 41, rectifier 42, second-stage separator 43, manifold 44, three-level separator 45 and water conservancy diversion collection ring 46.Such as Fig. 3
It is shown, the primary separator 41, second-stage separator 43 and three-level separator 45 include with the dedusting demisting monotubular 40 in
The connected retainer ring 411 of wall overlaps the central shaft 412 and multiple that set with the axis of the retainer ring 411 along the central shaft 412
Circumferential equally distributed swirl vane 413, multiple other ends of the swirl vane 413 are fixedly connected the retainer ring 411.It is described
The spacing between the swirl vane 413 on primary separator 41, second-stage separator 43 and three-level separator 45 is gradually reduced,
Specifically, the spacing between the swirl vane 413 on the primary separator 41 is 25~30mm；The second-stage separator
The spacing between the swirl vane 413 on 43 is 20~25mm；The swirl vane 413 on the three-level separator 45
Between spacing be 15~20mm.In order to ensure preferably to collect the liquid for gathering, remittance is provided with the swirl vane 413
Ji Gou, collector groove is provided with the inwall of dedusting demisting monotubular 40.
Operation principle of the invention：Flue gas enters the dedusting demisting cavity from the air inlet 11, subsequently into multiple
The dedusting demisting monotubular 40 carries out purified treatment, finally via the gas of the discharge purification of the gas outlet 12.Specifically, flue gas
Purification process in each described dedusting demisting monotubular 40 is as follows, and flue gas first passes through the primary separator 41, is set in inclination
Under the guide functions of the swirl vane 413 put, the gas of direct current starts rotation and rises, and flue gas rotates uphill process in speed and direction changing
It is middle produce turbulent flow, realize flow of flue gas state by direct current shape transition curl, make the big droplet and big grit phase in flue gas
Mutually collide, be bonded, being condensed into larger dust-laden drop, drop becomes larger after constantly accumulation and comes together in the eddy flow leaf
Collecting in ditch on piece 413, because the drop that is carried in flue gas and flue gas, the separation inertia of flue dust are different, can cause inertia compared with
Big drop, flue dust collect the collector groove that ditch is thrown on the inwall of dedusting demisting monotubular 40 described in, and collect along described
Groove flows into the liquid collector 20, because the spacing of the swirl vane 413 of the primary separator 41 is larger, flue gas flow rate change compared with
It is small, the grit and droplet of the bulky grain in flue gas can be removed.Continuing by the flue gas after the separation of the primary separator 41
During flowing up, by the rectification of the rectifier 42, flow of flue gas state is transited into direct current shape by helical form, gone forward side by side again
One step improves flue gas flow rate.Through the direct current flue gas after the rectification of the rectifier 42, proceed immediately to the second-stage separator 43 and enter
Row purification separation again, because the swirl vane 413 of the second-stage separator 43 is smaller than the primary separator 41
The spacing of swirl vane 413, when by the second-stage separator 43, rotation flow velocity is bigger, and inertia is stronger for flue gas, therefore, it is possible to
Remove the grit and droplet of larger particles in flue gas.Flue gas after the second-stage separator 43 is further separated, and then
Into the manifold 44, tiny drop and the grit collision probability in the manifold 44 are significantly increased, so that further
It is condensed into drop and flows into the liquid collector 20.Can be carried out more via the three-level separator 45 by flue gas after the manifold 44
Profound isolation of purified, because the spacing of the swirl vane 413 of the three-level separator 45 further reduces, can cause flue gas
Rotation flow velocity further lifted, the droplet and grit smaller such that it is able to separate particle so that flue gas is thoroughly purified.It is thorough
Flue gas after purification can enter the water conservancy diversion collection ring 46, be produced with the phenomenon for avoiding secondary elegant entrainment, eventually through described
Discharge the gas outlet 12 on the top of housing 10.After multiple long-plays of dedusting demisting monotubular 40, inside can accumulate
Certain dust and dirt, now, the controllable flusher 30 is started running, and certain speed is produced by multiple shower nozzles 31
Current are rinsed to multiple dedusting demisting monotubulars 40, and the sewage after flushing eventually flows into the liquid collector 20.
Beneficial effects of the present invention：By interval setting primary separator, rectifier, second-stage separator, manifold successively
With three-level separator, the swirl vane spacing being gradually reduced using primary separator, second-stage separator and three-level separator, with by
Step improves the flow velocity of gas, and enhancing dedusting removes fog effect, and has widened the use scope that the vortex restrains dedusting demister, can
To ensure the normal work when BMCR is as 30%-110% scopes.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and
Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
