Be generally 450-460mm with die opening in the dust arrester 23 at present, because less with die opening, more easily collecting is to the dust of larger particles, in order further to improve the efficiency of dust collection of Mobile pole plate electric cleaner, in the Mobile pole plate electric cleaner that above-described embodiment provides, the same die opening of the first Mobile pole plate dust arrester 231 is 450mm, the same die opening of the second Mobile pole plate dust arrester 232 is 420mm, the spacing that is adjacent two the first dust collecting pole plates 2311 is 450mm, the spacing of two adjacent the second dust collecting pole plates 2325 is 420mm, the spacing of two adjacent the first corona wires 2313 is 450mm, and the spacing of two adjacent the second corona wires 2326 is 420mm.By reducing the same die opening in the second Mobile pole plate dust arrester 232, strengthened the collection to the larger particles dust, and then improved the efficiency of dust collection of this Mobile pole plate electric cleaner.Certainly, the same die opening in the first Mobile pole plate dust arrester 231 and the second Mobile pole plate dust arrester 232 also can be other values, and the embodiment of the invention does not limit particularly to this.
In order further to improve the efficiency of dust collection of Mobile pole plate electric cleaner, in the Mobile pole plate electric cleaner that above-described embodiment provides, the second Mobile pole plate dust arrester 232 is adjacent with the first Mobile pole plate dust arrester 231, the first corona wire 2313 of the first Mobile pole plate dust arrester 231 and the second corona wire 2326 in the second Mobile pole plate dust arrester 232 all are longer than the 3rd corona wire of the dust arrester 23 that is positioned at the second Mobile pole plate dust arrester 232 front ends, and be longer than at least 1m, namely the first corona wire 2313 and the second corona wire 2326 are longer than respectively the 3rd corona wire 1m.Owing to existing the part dust directly to be discharged from from the top of corona wire, so increase the length of the first corona wire 2313 and the second corona wire 2326, reduced and directly discharged the Dust Capacity of housing 21 from housing 21 tops, thereby improved the efficiency of dust collection of Mobile pole plate electric cleaner.
In order to reduce the electric current between pole plate and to improve the uniformity of plate current density, corona wire uses the line style of line electric discharge type, preferably, it is linear that the first corona wire 2313 of the first Mobile pole plate dust arrester 231 and the second corona wire 2326 in the second Mobile pole plate dust arrester 232 are respectively fried dough twist, as shown in Figure 7.The first corona wire 2313 and/or the second corona wire 2326 also can be astroid, as shown in Figure 8, certainly, also can use the corona wire of an electric discharge type, be that this corona wire is so that the electric current between pole plate is larger, current density is more inhomogeneous, and the embodiment of the invention does not limit particularly to the shape of corona wire.
In order to guarantee that above-mentioned Mobile pole plate electric cleaner has better security, first initiatively back shaft and second initiatively back shaft all by fatigue design, and projected life be infinite life.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can be in the situation that do not break away from the spirit or scope of the present invention, in other embodiments realization.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
