The purpose of this utility model is to provide a kind of cyclone dust removal and two kinds of dust collection methods of cyclone electrostatic dedusting of integrating, and in the cyclone electrostatic dust pelletizing system, reaching the dedusting effect with the dust-cleaning principle of similar revolution electric field, reasonable in design, compact conformation, consumable quantity be little, remove big, the tangible spiral-flow type electrostatic precipitator of dust removing effects of dust quantity.
In order to achieve the above object, spiral-flow type electrostatic precipitator described in the utility model comprises dust arrester and vibrator.Dust arrester is made up of cyclone system and cyclone electrostatic dust pelletizing system, in the cyclone electrostatic dust pelletizing system, be provided with fixedly discharge electrode, dusty gas after the cyclone system dedusting divides upper and lower passage to enter the cyclone electrostatic dust pelletizing system, is respectively equipped with in the import of upper and lower passage the dusty gas swirl velocity is accelerated and the whirlwind guide vane and the single flow swirl vane of direction unanimity.
Owing to adopted cyclone system and cyclone electrostatic dust pelletizing system in the technique scheme, in the cyclone electrostatic dust pelletizing system, be provided with fixedly discharge electrode, the grit that some quality are bigger at first is removed in cyclone system; Remaining dusty gas enters the cyclone electrostatic dust pelletizing system after upper and lower channel entrance is accelerated, and forms strong eddy flow.In electrostatic field, dust is ionized, and is removed under the acting in conjunction of electric field force and centrifugal force.Thereby realized that the change discharge electrode rotates to dusty gas rotates, reached the purpose of carrying out dedusting with the dust-cleaning principle of similar revolution electric field, also solved the Insulation Problems of discharge electrode simultaneously.Spiral-flow type electrostatic precipitator described in the utility model is to integrate cyclone dust removal and cyclone electrostatic dedusting advantage, have reasonable in design, compact conformation, consumable quantity little, remove big, the tangible advantage of dust removing effects of dust quantity.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is the structural representation of spiral-flow type electrostatic precipitator described in the utility model;
Fig. 2 is the cutaway view of spiral-flow type electrostatic precipitator shown in Figure 1 along the A-A line.
By Fig. 1 and Fig. 2 as seen, spiral-flow type electrostatic precipitator described in the utility model comprises dust arrester and vibrator 16, and dust arrester is made up of cyclone system and cyclone electrostatic dust pelletizing system.Cyclone system is by upper box 1, promptly the volute housing, tubularly be close to paths 2, butterfly valve 3, shutter dust-precipitator 4, inertia ash-collecting tube 5, gravity type air valve 6, be that double-deck automatic panel-turnover valve is formed.The cyclone electrostatic dust pelletizing system is by: the whirlwind guide vane 7 of upper box 1 bottom, fixing arranging the annular dust collector pole 9 and the lower box that form by pipe and form in the outer barrel dust collector pole 8 of discharge electrode, discharge electrode and the discharge electrode.Fixedly discharge electrode is an annular combination discharge electrode, and every group of discharge electrode arranged the auxiliary electrode 11 that forms by the pipe discharge electrode 10 of a hairtail spur and several pipes and formed.Lower box is mainly by radiation shield 12, ash bucket 13, single flow swirl vane 14 and star discharge valve 15, promptly automatically the revolution ash-valve is formed.
The dusty gas that has certain inlet velocity at first enters the upper box 1 of cyclone system by air inlet, be to rotate in the volute housing, after the grit that some quality are bigger is assembled under action of centrifugal force, enter tubular type through diffluence pass and be close to paths 2, be close to paths 2 bottoms in tubular type and collected, and finally fall in the inertia ash-collecting tube 5 by shutter dust-precipitator 4.The remaining gas that has a small amount of grit forms rotational gas flow in the cyclone electrostatic dust pelletizing system after passage is quickened by the single flow swirl vane on the lower box 14.Be close in tubular type and be provided with butterfly valve 3 on the paths 2, regulate chimneyings, reach adjusting enters the dusty gas of cyclone electrostatic dust pelletizing system through single flow swirl vane 14 from the bottom flow by butterfly valve 3.
At upper box 1, be to be removed in the volute housing to enter the cyclone electrostatic dust pelletizing system after dusty gas behind a part of grit is quickened by the whirlwind guide vane under the upper box 17, form rotational gas flow down, because it is identical with the dusty gas eddy flow direction that enters the cyclone electrostatic dust pelletizing system from lower box from upper box 1, so two strands of air-flows are met in the cyclone electrostatic dust pelletizing system and are formed strong eddy flow, in the electric field of fixing discharge electrode, dust is ionized, charged dust is under electric field force and centrifugal force acting in conjunction, move to barrel dust collector pole 8, and be collected into barrel dust collector pole 8 surfaces, a spot of dust is to annular dust collector pole 9 motions of being made up of pipe at fixing discharge electrode center, and is collected into annular dust collector pole 9 surfaces.Thereby realized carrying out with the dust-cleaning principle of similar revolution electric field the purpose of dedusting, because the effect of gravity, dust finally drops in the ash bucket 13 of lower box.
When if the dust on dust collector pole 8,9 or the shutter dust-precipitator 4 can not in time drop to ash bucket 13 or inertia ash-collecting tube 5, then can remove by the rapping of vibrator 16.
