Adhere to particles to reduce discharge capacity. In addition, the dust collection efficiency η can be obtained according to the equation (1). Where A is the area of the collecting plate, Q is the air volume, and w is the drifting speed of the particles. However, there is still a large amount of space available between the collecting plates 12 of the prior art to add a collecting plate, thereby increasing the collecting plate area. Therefore, the dust collection efficiency η is still not maximized. Moreover, since the upper and lower sides of the prior art collecting plate 12 are not closed, the design of the prior art parallel collecting plate 12 will cause the problem of particle scattering, thereby reducing the flow of air into the dust collecting module and reducing the flow rate. The amount of gas that can be processed per unit of time.

Therefore, how to effectively increase the area of the collecting plate, avoid the adhesion of the side surface of the discharge portion, and avoid the problem of particle scattering caused by the design of the parallel collecting plate is a major problem for those skilled in the art.

Further, in the discharge portion of the present invention, the electric charge is charged, and the collecting portion has a charge having a polarity opposite to that of the electric discharge portion, or the collecting portion is grounded. Further, the collecting portion is composed of a plurality of plates or integrally formed. When the collecting portion is composed of a plurality of plates, the plates have coupling portions adapted to each other, so that the plates are combined into the collecting portion having the collecting units.

Furthermore, when the outer portion of the collecting portion of the present invention has a protruding portion, the dust collecting module further includes a outer frame having an inner side surface to surround the outer portion of the collecting portion. And the inner side surface has a plurality of outer frame grooves for the protrusion to be inserted. Moreover, the dust collecting module of the present invention further includes a seat having a plurality of openings corresponding to the upper surface and the lower surface and corresponding to the upper surface and the lower surface of the collecting unit, and the collecting portion is placed at the openings The upper surface is between the plurality of seat grooves between the openings of the upper surface for interposing the collecting portion.

The collecting unit 220 of the complete inner surface 220a of the side surface of the discharge portion 20 can obtain a greatly increased additional collection area in the fixed volume, thereby achieving the dust collecting efficiency of the equation (1) by increasing the collection area. effect. In addition, since the collecting unit 220 of the present invention has a "complete" inner surface 220a surrounding a side surface of a discharge portion 20, that is, the inner surface 220a has no gap Or opening, so that the airflow does not generate particles when the airflow passes through the collecting unit 220, that is, the inflow airflow leaks from the incomplete inner surface 220a, thereby maintaining the flow of the airflow into the dust collecting module, thereby greatly increasing the unit time. The amount of gas that can be handled inside. Furthermore, since the airflow passes through the entire collecting unit 220 in the longitudinal direction (ie, the airflow direction A is parallel to the longitudinal direction of the discharge portion 20), the contact area of the discharge portion 20 with the airflow particles can be minimized to avoid the entire prior art.
