Fig. 10 is a schematic perspective view of an electric field device including discharge electrodes and adsorption electrodes according to an embodiment of the present invention.
In the present embodiment, the electric field device includes a plurality of discharge electrodes including a first discharge electrode 619, a second discharge electrode 629, a third discharge electrode 639, a fourth discharge electrode 649, and the remaining eight discharge electrodes, and an adsorption electrode which is the electric field adsorption device 1100 shown in fig. 9A and 9B, and the plurality of electric field units in the electric field adsorption device 1100 have the same structural form. The adsorption pole refers to the related description of the electric field adsorption device shown in fig. 9A and 9B, and will not be described in detail here. As shown in fig. 10, no air inlet hole or air outlet hole is provided at the portion of each side wall of each electric field unit at the shortest distance 617 from the discharge electrode, for example, when the cross section of the channel of the electric field unit perpendicular to the axis is a regular polygon, no air inlet hole or air outlet hole is provided at the center line of each side wall (the electric field adsorption device shown in fig. 9A and 9B). For example, the portion of each sidewall of the first electric field unit 610 closest to the discharge electrode 619 is not provided with an air inlet hole or an air outlet hole, so that the portion forms a dust collecting portion.
Referring to fig. 10, the first discharge electrode 619 is inserted into the channel of the first electric field unit 610, a first electric field is formed between the first discharge electrode 619 and the first electric field unit 610, a second electric field, a third electric field, and a fourth electric field are respectively formed by the second electric field unit 620, the third electric field unit 630, the fourth electric field unit 640, the second discharge electrode 629, the third discharge electrode 639, and the fourth discharge electrode 649, and so on, and the rest of the electric field units respectively form an electric field with one discharge electrode.
Because the cross section of the channel of each electric field unit, which is surrounded by the side wall and is vertical to the axial direction, is a regular hexagon, the discharge electrode is preferably arranged parallel to the side wall of the channel and passes through the center of the inscribed circle of the cross section of the corresponding electric field unit, and the discharge efficiency is highest here. For example, a first discharge electrode 619 is disposed within the channel of the first electric field unit 610, and is preferably disposed parallel to the sidewall of the channel and passes through the center of the inscribed circle of the cross-section of the first electric field unit 610, and so on for the relationship of the other discharge electrodes to the electric field unit.

In addition, because the first electric field has two inclined planes, the air current flows more disorderly in hollow first electric field unit 610 because of the air inlet of the inclined planes, and after the collision with the side wall is increased, the frequency of passing through the vicinity of first discharge electrode 619 is improved, so that the adsorption efficiency is higher. After the first electric field treatment, the gas is discharged from the gas outlets on the third sidewall 613, the fourth sidewall 614, and the fifth sidewall 615, and enters the second electric field and the third electric field through the gas outlets on the third sidewall 613 and the fifth sidewall 615.
For the second electric field, a part of gas enters the second electric field through the gas inlet holes on the fourth side wall 624 and the fifth side wall 625 in the adsorption unit 620 of the second electric field, another part of gas from the first electric field enters the second electric field through the holes on the third side wall 613 in the first electric field unit 610, the gas entering direction is not perpendicular to the ion flow direction in the second electric field, due to the staggered arrangement of the gas inlet holes and the gas outlet holes, the gas flow is turbulent in the hollow electric field unit 620, the more the gas flow passing through the vicinity of the discharge electrode 629, the more the particulate matters collide with the second discharge electrode 629, the more the charged particles are, and the adsorption efficiency is improved. In addition, because the second electric field still has an inclined plane, and in the same way, the inclined plane air inlet makes the air current flow more disorderly in hollow second electric field unit 620, and adsorption efficiency is higher. After the second electric field treatment, the gas is discharged from the gas outlets on the first side wall 621, the second side wall 622, and the third side wall 623 of the second electric field unit 620.
For the third electric field, a part of gas enters the third electric field through the gas inlet holes on the fifth side wall 635 in the third electric field unit 630, another part of gas from the first electric field through the holes on the fifth side wall 615 in the first electric field unit 610 and gas from the fourth electric field through the holes on the fourth side wall 634 in the third electric field unit 630 enter the third electric field, the gas entering direction is not perpendicular to the ion flow direction in the third electric field, due to the staggered arrangement of the gas inlet holes and the gas outlet holes, the gas flow is disturbed in the hollow third electric field unit 630, the more gas flow passing through the vicinity of the discharge electrode 639, the more particulate matters collide with the third discharge electrode 639, the more charged particles are, and the adsorption efficiency is improved. After the third electric field treatment, the gas is discharged from the gas outlets on the first side wall 631, the second side wall 632, and the third side wall 633 of the third electric field unit 630.
And similarly, the process that the gas enters other electric field generating units is analogized.
The electric field unit of this embodiment electric field device has the structure of trompil on the lateral wall, makes gas flow disorder in the electric field through the side air inlet, and the collision increases with third discharge electrode 639, and the charged particle increases, has improved holistic adsorption efficiency.
