The beneficial effects of the utility model are:
1. improved the efficiency of dust collection of electrostatic precipitator.Changed the set-up mode of dust collecting electrode and corona discharge electrode because of the utility model, downstream direction changed into meet airflow direction, promptly vertical with airflow direction, (wind speed can reach 4.0m/s to have strengthened the wind speed of air-introduced machine simultaneously, compare with prior art 1.2m/s and to have improved nearly 4 times), accelerated grit in the dust collecting electrode boundary layer and driven into sum velocity, thereby improved efficiency of dust collection to dust collecting electrode.
2, do not produce reentrainment of dust.Because of the utility model has changed the shape of control of dust pole plate, promptly by original plate shaped two C flute profiles that change into, the dust Control that falls down in the time of can be with rapping is added the inhibitory action of electric field Coulomb force in two C grooves, therefore can not produce the secondary fly-up of dust.
3, dwindle the volume of deduster, reduced cost.In order to increase air velocity, to improve efficiency of dust collection, the utility model adopts sectional area that dwindles the electric cleaner electric field and the method that strengthens the air-introduced machine air quantity.Therefore, the volume of big wind speed deduster reduces to some extent, has realized the miniaturization of electric cleaner, has saved steel, and one-time investment reduces, and manufacturing, installation, maintenance and administrative expenses all can reduce.

The specific embodiment
The utlity model has the shell 1 that air inlet 2, air outlet 4 are set, corona discharge electrode 5 and dust collecting electrode that parallel equidistant is provided with are installed in shell 1, the ash bucket 9 that has ash exhauster 8 is installed in shell 1 bottom, the beater of rapping apparatus 3 is installed on the bottom of corona discharge electrode 5 and control of dust pole plate 6, control of dust pole plate 6 is two C grooveds, direction is set for meeting airflow direction, promptly vertical with airflow direction; Corona discharge electrode 5 direction is set also for meeting airflow direction, parallel with control of dust pole plate 6; Described corona discharge electrode 5 is a plurality of (present embodiment is 14), corona discharge electrode 5 alternate settings with dust collecting electrode, vertically be provided with a plurality of control of dust pole plates 6 (present embodiment is 5 or 6) in each dust collecting electrode, being provided with between adjacent two control of dust pole plates 6 can be by the gap 7 of air-flow, and gap 7 is corresponding with control of dust pole plate 6 centers in the dust collecting electrode of being separated by by corona discharge electrode 5.
Operation principle of the present utility model is:
Control of dust pole plate of the present utility model 6 adopts two C grooveds, and for meeting the airflow direction setting, and the dust Control that the control of dust pole plate 6 of this shape falls down in the time of can be rapping is added the inhibitory action of electric field Coulomb force in two C grooves, can not produce reentrainment of dust.
The utility model changes corona discharge electrode 5 and dust collecting electrode into and meets the airflow direction setting from downstream direction, thereby has improved the migration velocity of grit to dust collecting electrode, as shown in Figure 4, when control of dust pole plate 6 downstream directions are installed in the dust collecting electrode boundary layer sum velocity of grit
For vector closes; As shown in Figure 5, control of dust pole plate 6 meet airflow direction when installing in the dust collecting electrode boundary layer sum velocity v of grit
Close=v+w is for algebraically closes, wherein
Be air velocity,
Be migration velocity (down together); Therefore
Therefore the efficiency of dust collection of electrostatic precipitator is to meet airflow direction greater than downstream direction, and this is one of characteristics of the present utility model.
The utility model has strengthened air velocity and effect thereof in the electric field, its way that strengthens air velocity is the air quantity that dwindles the sectional area of electric cleaner electric field and strengthen air-introduced machine, under the condition after the improvement, the efficiency of dust collection of equipment is not only unaffected, can also improve its efficiency of dust collection on the contrary.Its principle is that air-flow is to detour along control of dust pole plate 6 inner surfaces in electric field, so just prolonged the movement locus of grit greatly, add of the progradation of the interior air velocity of electric field to grit, can be driven to the dust collecting electrode surface to grit with very big speed in the short period of time and be captured, thereby improve the efficiency of dust collection of equipment.
The utility model control of dust pole plate 6 changes another effect of meeting the airflow direction installation into:
Boundary layer thickness is before improving:
The run duration of grit in boundary layer when wherein Δ tp is provided with for the dust collecting electrode downstream direction;
Improving the back boundary layer thickness is: δ n=Δ tn * (w+v)
Wherein Δ tn is that dust collecting electrode is met airflow direction grit run duration in the boundary layer when being provided with;
More as can be seen because δ n＜δ p, Δ tn＜Δ tp just, so control of dust has very met the airflow direction time decreased that grit is captured by control of dust pole plate 6 when being provided with from last two formulas, from and improved the efficiency of dust collection of this equipment.
The course of work of the present utility model is as follows:
After air-introduced machine started, the gas that has grit entered in the deduster shell 1 from air inlet 2, and the corona discharge electrode 5 that feeds high voltage direct current discharges a large amount of electron ion attached on the grit, grit under the effect of wind-force and Coulomb force with sum velocity (algebraical sum) v
Close=v+w drives into to dust collecting electrode fast, grit two C groove inner surfaces along control of dust pole plate 6 in electric field detour, the grit that has negative electrical charge in a large number is very fast by 6 captures of control of dust pole plate, the grit that is partly with positive charge is captured by corona collection 5, the grit that neutral grit or remainder have electric charge enters the next stage electric field by further charged by gap 7 under the effect of air-introduced machine, capture, because of each gap all corresponding with a center of meeting two C grooved control of dust pole plates 6 that airflow direction is provided with on downstream direction, charged grit is again very fast by control of dust pole plate 6 in this grade electric field or corona discharge electrode 5 captures under the effect of wind-force and electric field Coulomb force, remaining gas enters next stage electric field again by gap 7 again, grit is captured until to air outlet 4 by the one-level one-level, is discharged from through purified gas; Attached to the grit on corona discharge electrode 5 or the control of dust pole plate 6 under the knocking of rapping apparatus 3 vibration hammers in corona discharge electrode or two C groove drop ash bucket 9, rather than diffusion has everywhere suppressed the secondary fly-up of dust effectively, after ash exhauster 8 discharge.
