The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in detail.
Consult shown in Fig. 1 to Fig. 5, a kind of MBE type mobile electrode electric precipitator that the utility model discloses (in MBE, the abbreviation that M is Moving, is interpreted as moving, and BE is BE structure electric field), comprises preposition electric field 1 and last electric field 2.
Wherein, BE structure electric field is set in preposition electric field 1, end electric field 2 arranges traveling electrode structure electric field, in BE structure electric field, positive plate 11 is arranged a plurality of gas channels along airflow direction, this gas channel is communicated with the gas channel being arranged in traveling electrode structure electric field, and the utility model is combined BE structure electric field and traveling electrode structure electric field, and the advantage that is about to BE structure electric field and traveling electrode structure electric field is combined.
In BE structure electric field, positive plate 11 hangs by the boatswain chair of housing back timber 12 bottoms, between two suspension centres, arranges positive plate more an anode top electromagnetic vibratory hammer device 13 is set.Negative electrode frame 14 is arranged between two positive plates 11, and cathode line is arranged on negative electrode frame 14, and negative electrode frame 14 hangs fine strain of millet 15 by negative electrode and is fixed on two top boards 16 between back timber 12, arranges negative electrode frame 14 more and shares a cathode top electromagnetic vibratory hammer device 17.BE structure electric field is existing mature technology, is not described in further detail herein.
End electric field 2 arranges traveling electrode structure electric field, and its moving anode plate 21 is divided into interconnective polylith sheet positive plate in electric field short transverse, and as shown in Figure 2, described polylith sheet positive plate moves up and down along direction of an electric field under transmission device 22 transmissions.
