Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiment is a part of the embodiments of the present invention, rather than whole embodiments.Based on this hair
Embodiment in bright, those of ordinary skill in the art's every other reality obtained without making creative work
Example is applied, all should belong to the scope of protection of the invention.
In order to promote the dust removal performance of interior whirlpool type electrostatic cyclone, magnetic field is introduced into deduster inner space herein,
It is preferably distributed in inside deduster by the negative ions that magnetic fields generate corona discharge and dust is improved with this
Grain it is charged, and then improve efficiency of dust collection.On the basis of analyzing dust removal mechanism, using the method for numerical simulation to Analysis on Mechanism
Conclusion has made further verifying, and has obtained dedusting effect of the interior whirlpool type electrostatic cyclone under different operating conditions under magnetic fields
Rate, known to after comparative analysis: (1) in interior whirlpool type electrostatic cyclone, magnetic field can effectively facilitate negative ions and electrification
Grain moves to outer vortex air flow descending area from interior vortex air flow rising area, increases charging particle, reduces particle escape, improves and remove
The trapping performance of dirt device；(2) under identical operating condition, efficiency of dust collection increases with the increase of magnetic induction intensity, but amplification subtracts therewith
It is small；(3) as operating voltage reduces, inlet velocity increases, magnetic field constantly enhances the castering action of efficiency of dust collection.
1, electromagnetism cyclone dust removal mechanism
In interior whirlpool type electrostatic cyclone, corona wire is located at cyclone dust collectors pipeline center, along corona wire direction
Apply magnetic field, magnetic field covers entire cyclone dust collectors particle motor area, as shown in Figure 1.If applying negative high voltage on polar curve, electric field
Wall is directed toward backwards to wall, the direction of electric field force in the direction of E, and electronics keeps dust particles negatively charged during moving hair to wall,
The particle of bear electricity moves under electric field force and centrifugal force effect to wall, as shown in Fig. 1 (a).If applying on polar curve positive high
The direction of pressure, electric field and electric field force is directed to wall, and cation is collided with grit during moving to wall and adhered to thereon
It is allowed to lotus positive electricity, the particle of lotus positive electricity moves under electric field force and centrifugal force effect towards wall direction, as shown in Fig. 1 (b).
Since the installation site of corona wire is in interior vortex air flow rising area, the negative ions that a part of corona discharge generates do not have also
Have to come into full contact with dust particles and be just raised air-flow and taken electrostatic cyclone out of, so that the dust particles in the area Wai Wo are charged
It is insufficient, and then the problem of cause efficiency of dust collection to reduce.In order to efficiently solve this problem, magnetic field is introduced into electrostatic rotating here
Wind deduster, to produce new dust removal mechanism, as electromagnetism cyclone dust removal mechanism.
After introducing magnetic field B, negative ions are with electrification dust because of the connection by electric field force and Lorentz force under magnetic field environment
Cooperation is used as more complicated screw, on the one hand, promotes the outside vortex air flow of negative ions in interior vortex air flow rising area
The movement of descending area, so that the area Wai Wo dust particles are charged more sufficiently, on the other hand, so that a part of dust charge at large
Electric particle moves to outer vortex air flow descending area again, and then is re-introduced into dust collection area, to improve interior whirlpool type electrostatic
The dust removal performance of cyclone dust collectors.
2, the magnetic fields analysis under different operating conditions
For analyzing as a result, the electrostatic cyclone threedimensional model of foundation is imported for verifying electromagnetic cyclone dust removal mechanism
FLUENT, the efficiency of dust collection of interior whirlpool type electrostatic cyclone under numerical simulation magnetic fields, analyze different operating voltage and

It gradually tends towards stability, illustrates that operating voltage increases the facilitation of efficiency of dust collection with voltage and weakens；
2) difference of adjacent two curves gradually becomes smaller with the increase of operating voltage, illustrates magnetic field to efficiency of dust collection
Castering action is increased with voltage and is reduced, this may be interpreted as, and voltage raising enhances interior whirlpool type electrostatic cyclone electric field, interior
The negative ions and charged particle of whirlpool area movement can weaken magnetic field and exist by strong electrical field action to outer whirlpool hyperbar
Effect during this thereby reduces magnetic field to the castering action of electrostatic cyclone efficiency of dust collection；
3) under same operating voltage, efficiency of dust collection increases with magnetic induction intensity and is increased, but amplification reduces therewith, explanation
Magnetic field increases the facilitation of efficiency of dust collection with magnetic induction intensity and weakens, this is because magnetic induction intensity reaches certain value

It tends towards stability, illustrates that the raising of inlet velocity reduces the charged effect of particle, reduce the action time of electric field force, to drop
Low efficiency of dust collection；
2) difference of adjacent two curves becomes larger with the raising of inlet velocity, illustrates that inlet velocity is higher, magnetic
The effect that field plays is bigger, this can be construed to, and the raising of inlet velocity results in the raising of the interior vortex air flow rate of climb, air-flow
The negative ions and charged particle of corona discharge generation have quickly been taken away, so that efficiency of dust collection aggravates, however have introduced magnetic
After, the raising of inlet velocity has also resulted in the increase of Lorentz force, this effectively promotes negative ions and charged particle
The movement of outside vortex air flow descending area, slowing down interior whirlpool ascending air makes the loss in vain of negative ions, the area Shi Waiwo dust
Grain it is charged more sufficiently, reduce charged particle escape, to effectively increase efficiency of dust collection；
3) under same inlet velocity, efficiency of dust collection increases as magnetic induction intensity increases, but its amplification constantly reduces, and says
Bright as magnetic induction intensity increases, the castering action of dust removal performance is being weakened in magnetic field, this is because larger in magnetic induction intensity
When, by way of increasing magnetic induction intensity the movement of negative ions and charged particle from the area Nei Wo to the area Wai Wo cannot occur
Significant change.
