Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is described in further detail, and embodiment of the present utility model includes but not limited to the following example.
Embodiment
As shown in Fig. 1 ~ 8, a kind of centrifugal type demister, comprises equilateral hexagon cylindrical shell 1, is arranged at the centrifugal compounded plate group 2 of bottom in equilateral hexagon cylindrical shell, and is arranged at the wash tub pipe assembly 3 of equilateral hexagon cylindrical shell outer bottom; Also be provided with in described equilateral hexagon cylindrical shell and be connected with wash tub pipe assembly and run through the Flushing nozzle 4 of centrifugal compounded plate group.According to actual conditions, multiple demister of the present utility model can be adopted, during concrete operations mode, multiple demister is connected successively from top to bottom, arrange grid type demister support at side to be fixed, make each demister of the present utility model keep up and down near, thus realize relatively fixing, thus meet required demist effective area.
When using the utility model, flue gas is entered by the bottom of demister, upwards flows, and reaches dedusting, demist effect through centrifugal compounded plate group; Meanwhile, the flue gas flowing through centrifugal compounded plate group forms eddy flow in equilateral hexagon cylindrical shell, causes remaining most of dirt, mist in flue gas to invest on barrel, and with barrel downstream to slurry pool.
Particularly, it is orthohexagonal cylindrical shell 11 that described equilateral hexagon cylindrical shell comprises cross section, and is arranged at the fixture 12 for fixing centrifugal compounded plate group on cylinder lateral wall; The end of described centrifugal compounded plate group is then fixed on fixture.Centrifugal compounded plate group can be fixed on bearing, easy installation and removal by above-mentioned setting.
Described centrifugal compounded plate group comprises center retainer ring 21, and is arranged at several blades 22 of center retainer ring surrounding; All blade leans are arranged, and are uniformly distributed in center retainer ring surrounding.Wherein, described blade plane is varied angle, and namely blade plane and horizontal plane angle α are 20 ° ~ 50 °, and blade top and horizontal plane angle are-5 ° ~ 20 °; It is 5 ° ~ 15 ° at blade air outlet edge knuckle β, β, to form blade flanging shape.By above-mentioned restriction, make blade be distributed in center retainer ring surrounding uniformly, and define the angle of blade, thus make flue gas can not prolong straight line to rise, but can ascending track be changed, from but flue gas forms eddy flow.Concrete, flue gas through centrifugal compounded plate group, due to special design make dirt, mist is more prone to is removed, also can be flue gas easier formation eddy flow when upwards flowing, thus greatly increase dedusting of the present utility model, demist effect.Certainly in order to control flue gas flow rate further, can add guide ring between multiple demister of the present utility model, thus can control the flow velocity of flue gas through each demister, that improves each demister removes fog effect.
Due to dust-laden in flue gas, reach a certain amount of containing mist, after demister, part dirt, mist can accumulate in centrifugal compounded plate group and equilateral hexagon cylinder inboard wall.For preventing longtime running fouling, blocking, in the utility model, be also provided with Flushing nozzle, and this Flushing nozzle is also connected to wash tub pipe assembly.Carry out interruption by Flushing nozzle to centrifugal compounded plate group and equilateral hexagon cylindrical shell to rinse, thus avoid fouling, clogging generation, improve dedusting accordingly, except fog effect; Rinse break time and rinse and continue duration, then regulate as the case may be.
But above-mentioned wash tub pipe assembly concrete structure is as follows: described wash tub pipe assembly comprises wash tub pipe 31, the wash tub pipe joint 32 be connected with wash tub pipe; Described wash tub pipe is connected with Flushing nozzle.Described Flushing nozzle is equilateral hexagonal cylindricality, and middle part is provided with the vertical passageway be communicated with wash tub pipe, and be provided with interconnection in vertical passageway surrounding, this interconnection end is then the outlet of flushing water simultaneously.Flush head of the present utility model can not only be communicated with external water pipe; When adopting multiple the utility model overlap to use, flush head can also be connected with the Flushing nozzle of another demister be positioned at below it.
What deserves to be explained is, the female pipe of water inlet supplied water for the utility model is positioned at bottom or the top of whole device when reality supplies water, thus conveniently to install, run, maintenance.
According to above-described embodiment, just the utility model can be realized well.What deserves to be explained is; under prerequisite based on said structure design; for solving same technical problem; even if some making on the utility model are without substantial change or polishing; the essence of the technical scheme adopted is still the same with the utility model, therefore it also should in protection domain of the present utility model.
