In Fig. 2, an electrode is made of a wall (12), and one of them face of this wall is provided with the fin (13) of some very thin thickness.The direction of these fins (13) is vertical with wall (12), but these fins are parallel to each other.The distance that adjacent two fins (13) separate to each other is about several microns.Wall (12) flow direction with air-flow (14) in housing (1) is vertical, and like this, fin (13) stretches abreast with airflow direction.For making air-flow can pass through the both sides of wall (12), this wall comprises that some run through its hole (15).These holes (15) occupy most of area of wall (12), and between adjacent two fins (13) along extending transversely.Connector (16) between the fin (13) is realized wall (12).The merging area of connector (16) is the merging area of (15) much smaller than the hole, thereby makes air-flow best by wall (12), the restriction windage loss.The merging area of connector (16) is essential just for enough mechanical strength is provided for electrode.Under the little situation of volume, such electrode has very big particle and collects the surface, the setting of electrode in this gathering-device (16) realizes that by arranging a unique member this member combines the wall (12) that connector (16) constitutes with the fin of combining to each other by these connectors (13).
In Fig. 3 a and 3b, just as shown in Figure 2, gathering-device (6) comprises pair of electrodes (7,8), each fin (13) of these two electrodes (7,8) is interlaced arrangement to each other, and a fin (13) of an electrode is clipped between two adjacent fins (13) of another electrode.The wall (12) of two electrodes (7,8) is parallel to each other, the connector separately (16) that these two electrodes are included and hole (15) setting that faces each other.This layout of connector (16) and hole (15) makes the windage loss minimum.The fin vis-a-vis (13) of these two electrodes (7,8) forms the gas channel (17) that extends to a relative hole (15) of another electrode from a hole (15) of an electrode.Utilize the electrode fin (13) relevant to attract and hold back and be brought into the interior charged particle of air-flow (14) with power supply terminal (10).
In Fig. 4 a and 4b, gathering-device comprises three electrodes (7,8,18), and these three electrodes are arranged in the air-flow in order.Target (18) is made of the electrode of form shown in two image pattern 3a and the 3b, and these two electrodes link to each other by their wall (12).This lean against formula can by welding, by bonding, by pleating or other can realize thisly being finished by the mechanical technique of mode.Two quilts against the hole (15) and the connector (16) of electrode preferably positioned opposite to each other respectively.From same type electrode, this layout can make particle collect surperficial optimization and/or increase filter capacity.
In Fig. 5 a and 5b, gathering-device (6) comprises three electrodes (7,8,18).Target (18) surface at its upstream comprises some fins (13) of alternately arranging with its downstream surface.Be in the fin (13) of target (18) upstream and downstream and the fin (13) of corresponding two tip electrodes respectively and be staggered, these two tip electrodes are exactly the sort of electrode shown in Fig. 3 a and the 3b.
No matter in 5b, is in the upstream of air-flow (14) or the wall (12) of the electrode in downstream (7,8,18) all comprises the hole (15) that allows air pass through at Fig. 3 a.
In Fig. 6, by to a metal tape (19) boring, and it is folding, so that the sort of electrode shown in shop drawings 3a and the 3b.Specifically, the first step making spreads all over belt (19) and cuts, and particularly cuts into rectangle, so that form each hole (15).Realize described cutting by the hole of belt (19) being bored the square or rectangular grid, like this, in these cuttings that distribute symmetrically of belt (19) upper edge multirow and multiple row.Some cutting wherein is to carry out according to the mode that fold line (20) is folded mutually, these fold lines are in order to form fin (13), these cuttings will be disintegrated the certain distance of line (21) and carried out, and this broken line is used to make two the adjacent solid area of this belt (19) between each cutting close mutually.In Fig. 6, fold line (20,21) is represented with chain-dotted line.
In 7e, belt (19) is folding along fold line (20) and broken line (21) at Fig. 7 a so that form the fin (13) of electrode, with the solid section of belt (19) between two row cuttings along broken line (21) to pressing down.In Fig. 7 f, two identical electrodes (7, the 8) arrangement interlaced with each other that will make according to above-mentioned method for folding is so that form the gathering-device shown in Fig. 3 a and the 3b.It should be noted that these two electrodes (7,8) are identical, they all are to make with identical method, have so just reduced the manufacturing cost of gathering-device (6).
In Fig. 8 a,, make plastics become conductor by metal-loaded particle or coating electrically conductive coating by the plastics that become conductor being pushed to make electrode.According to another kind of modification Implementation Modes, can make electrode by the extrusion metal material.In the first step shown in Fig. 8 a, obtain electrode by mold pressing, this electrode comprises a solid wall (22), and some fins (13) are arranged on one of them face of solid wall.In Fig. 8 b, give wall (22) boring of electrode, so that realize hole (15) and connector (16).According to another kind of Implementation Modes, can obtain electrode by the plastic material that mold pressing becomes conductor, make plastics become conductor by metal-loaded particle or coating electrically conductive coating.In this case, the electrode that becomes form shown in Fig. 8 b directly obtains by mold pressing.
In Fig. 9, first basic framework (23) has two combs (24), and these two combs are used to accept two staggered electrodes (7,8) fin (13) is so that guarantee to make electrode (7,8) accurately to locate between these two combs, guarantee the accurate location of fin (13) of each electrode (7,8) simultaneously.It should be noted that the fin (13) that this configuration of first basic framework (23) can be suitable for the electrode (7,8,18) that obtains with above-mentioned arbitrary Implementation Modes cooperates.These layouts will make each fin (13) keep accurately constant separation distance to each other, discharge between these fins so that prevent.First basic framework (23) forms by the solid memder that combines with comb (24), an outer wall (25) with the interconnective stiff rib of each outer wall (25) (26) of framework (23).Comb (24) stretches along the direction vertical with the fin (13) of its electrode that receives between two relative basic frameworks (23).Comb (24) preferably constitutes the mechanical reinforcement of framework (23), and comb is preferably relative with the connector (16) of electrode (7,8), so that make windage loss drop to minimum.
In Figure 10, first basic framework (23) and the common support that forms a framework (28) shape of second basic framework (27) assembling accommodate two staggered electrodes (7,8) in this support.By welding, by bonding, by inlaying, can realizing this assembling by methods such as folder pincers.The structure of second basic framework (27) is similar with first basic framework (23) preferably, just can be limited on the structural member, and described structural member for example by welding, by bonding, by inlaying, being fixed on first basic framework (23) by technology such as folder pincers etc.Framework (28) comprises an aperture (29), and this aperture constitutes the passage of the electrical connection mechanism separately (30) of each electrode (7,8), electrical connection mechanism respectively will be separately the corresponding electrode terminal (10) that is connected to power supply (11) go up and be connected with ground (9).Each electrical connection mechanism (30) is preferably disposed on the prolongation of one of them connector (16).Such layout can make gathering-device (6) be electrically connected easily.
Figure 11 and 12 is cutaway views of apparatus of the present invention.Framework (27) in the basic framework has comb (24).In Figure 11, analyse and observe in the interval in the hole (15) that comb (24) is occupied.In this interval, air-flow (14) can not pass through framework, and reason is that the part of comb (24) has occupied the air duct that hole (15) constitutes.In Figure 12, the interval in the hole (15) that do not occupied by comb (24) to be analysed and observe, this interval is used to allow air-flow (14) pass through.
