Abstract

The utility model relates to an electric dust collector with conductive filter cells. The electric dust collector comprises a plurality of anode plates and cathode wires arranged between the anode plates, and further comprises the conductive filter cells of which the quantity is the same as that of the anode plates, wherein the conductive filter cells are arranged at the tail ends of the anode plates; the conductive filter cells take the shapes of deep notches, the open ends of the conductive filter cells face to the tail ends of the field anode plates, and the other ends of the conductive filter cells are semicircular; breather holes are formed in the conductive filter cells. The electric dust collector has the benefits that dust with low specific resistance can be effectively collected; after dust with high specific resistance is collected by the conductive filter cells, a back-corona field can not be formed; as rapping and soot cleaning reentrainment is collected, the dust removal efficiency of the electric dust collector is remarkably improved.

Description

The electric cleaner of band conduction filter pocket
Technical field
The utility model relates to a kind of electric cleaner, relates in particular to the positive plate in this electric cleaner.
Background technology
Electrostatic precipitator be flue gas under the effect of high voltage electric field, air ionization makes the dust in flue gas charged, under electric field force effect, Charged moves to electrode, is deposited on gradually anode and cathode surface, and dust and flue gas are departed from, thereby reaches the object of purifying smoke.Along with domestic and international environmental administration is to the improving constantly of granular material discharged requirement, old electric cleaner major part is difficult to adapt to.Actual measurement shows, is best suited for the dust specific resistance value of electric cleaner work 10 6~10 11Ω cm.Beyond this number range, the performance of electric cleaner is fallen.
When flue dust has just entered the electric field of electric cleaner, the dust concentration of circulation section distributes substantially equally even, but the end to electric field, effect due to electric field force, the dust concentration of circulation section distributes and has greatly changed, trend is: in the space between dust collector pole and discharge electrode, higher the closer near dust concentration dust collector pole, and the dust concentration of discharge electrode is relatively low.Near dust collector pole, partial state of charge dust, owing to mutually repelling and part dust exists charged deficiency, can not be trapped by dust collector pole part dust, along with the air-flow electric field of escaping out along plate surface.In addition,, when electric field vibration dust-cleaning, most reentrainment of dust is also the electric field of escaping out along plate surface.So if can effectively trap the dust that electric field end is escaped along positive plate surface, the dust-collecting efficiency of electric cleaner will significantly improve.
Summary of the invention
The utility model technical issues that need to address have been to provide a kind of electric cleaner with conduction filter pocket, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: a plurality of positive plates and be placed in the cathode line between positive plate; Also comprise: with the conduction filter pocket of a plurality of positive plate same number; Described conduction filter pocket is placed in the end of positive plate; Described conduction filter pocket is deep trouth shape, and openend is facing to the end of electric field positive plate, other end semicircular in shape; On described conduction filter pocket, have air-vent.
Compared with prior art, the beneficial effects of the utility model are: effectively trap low resistivity dust; High resistivity dust is conducted electricity after filter pocket trapping, can not form anti-corona field; Trap the reentrainment of dust of vibration dust-cleaning, obviously improve the efficiency of dust collection of electric cleaner.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 conducts electricity filter pocket structural representation in Fig. 1.
Fig. 3 is electric field dust motion schematic diagram after employing the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described in further detail:
From Fig. 1, Fig. 2: the utility model comprises: a plurality of positive plates 1 and be placed in the cathode line 2 between positive plate 1; Also comprise: with the conduction filter pocket 3 of a plurality of positive plate 1 same number; Described conduction filter pocket 3 is placed in the end of positive plate 1; Described conduction filter pocket is deep trouth shape, and openend 31 is facing to the end of electric field positive plate 1, the other end 32 semicirculars in shape; On described conduction filter pocket, have air-vent 33.
The utility model comprises positive plate, cathode line, by negative electrode and high-voltage rectifying transformer, is connected to form high pressure charging area, and electric field end arranges conduction filter pocket.Conduction filter pocket is placed on the every row's pole plate of each electric field end, when trapping high resistivity dust, can not produce anti-corona; For easily charged low resistivity dust, because it is under electric field force and wind-force effect, its direction of motion is pointed to the import of conduction filter pocket (as shown in Figure 3, in figure: positive plate 1, cathode line 2 and conduction filter pocket 3; D represents electric field force, and F represents bisque, and L represents wind-force), the dust entering in groove is effectively trapped under Electrostatic Absorption and interception filtration double action.
