Specific embodiment
In the following, in conjunction with accompanying drawings and embodiments, the present invention is described in detail.
Embodiment one：
As shown in Figs. 1-5, the present invention provides a kind of based on the electrostatic precipitator for improving pole plate, including shell 1, the shell
1 lower section is provided with ash bucket 2, is provided with dust collecting pole plate 3 and cathode plate 4 in the shell 1；Dust collecting pole plate 3 and cathode plate 4 are by more
Group pole plate is constituted, and dust collecting pole plate 3 is parallel with adjacent cathode plate 4 and spacing is fixed.The dust collecting pole plate 3 by C480 pole plate 31,
Two blocks of plate type metal plates 32 and upper cover plate 34 assemble, the length and width dimensions of the plate type metal plate 32 and C480 pole plate 31
Identical, two blocks of plate type metal plates 32 are distinguished Matching installation and are opened on the both sides of C480 pole plate 31, the plate type metal plate 32
Equipped with through-hole 33, and the percent opening of through-hole 33 is 30%-80%, and the upper end of dust collecting pole plate 3 is closed with the upper cover plate 34, therefore is received
The two sides of dirt pole plate 3 respectively form the cavity that gathers dust of the relative closure of a lower ending opening.The cathode plate 4 is parallel by more
Metal tube 41 forms, fixed in the same plane by more metal bars 43 between the metal tube 41, on every metal tube 41
The hollow needle 42 of fixed two rows metal material, the cavity of hollow needle 42 are connected to the cavity of metal tube 41, the lower end of metal tube 41
It is closed, one cavity closed at one end of formation, the upper end of all metal tubes 41 is linked together by the tracheae 6 that insulate, structure
At a closed insulation gas circuit, vibrator 5 is provided on the dust collecting pole plate 3 and cathode plate 4.By test, the present invention is received
Dirt pole plate 3 increases 120% specific collection area compared with classic flat-plate type electric precipitator, greatly improves dust-collecting efficiency.
Embodiment two：
As shown in fig. 6, being with the difference of above-described embodiment one, there are two the settings of ash bucket 2.
Lower the working principle of the invention is described below：
When work, apply 10KV negative high voltage between dust collecting pole plate 3 and cathode plate 4, maintains one in two interpolars and be enough to make gas
The high voltage electric field of volume ionization can generate electronics and cation after gas ionization, when carrying the flue gas of dust into when crossing electric field, dust
Charge can be obtained and most of dust electric polarity is negative, in this way, dust is under the action of electric field force, moved to dust collecting pole plate 3, one
Part dust can be adsorbed on the solid face of dust collecting pole plate 3, remaining dust can enter dust collecting pole plate 3 and gather dust in cavity, and
Be closed under the action of electric field force gather dust it is intracavitary.Meanwhile the tip of hollow needle 42 can generate corona wind 9, direction is perpendicular to receipts
Dirt pole plate 3, the wind force intensified effect of electric field force of corona wind 9, strengthens dust and enters and be enclosed in intracavitary effect of gathering dust
Power.
While applying negative high voltage between dust collecting pole plate 3 and cathode plate 4, compressed air 7, compressed air are passed through into gas circuit
7 are discharged by hollow needle 42, are formd using 42 endpoint of hollow needle as starting point, wind-force of the direction perpendicular to dust collecting pole plate 3, electric field
The wind-force superposition for the wind 8 that power, the wind-force of corona wind 9 and compressed air are formed forms the resultant force perpendicular to dust collecting pole plate 3, into one
Step enhances the migration velocity of dedusting particle, while further enhancing dust and entering and be enclosed in the intracavitary active force that gathers dust,
The dust granule for entering electric field is firmly locked in the cavity that gathers dust of dust collecting pole plate 3.
5 Timing vibration of vibrator on dust collecting pole plate 3 and cathode plate 4, makes to be adsorbed on dust collecting pole plate 3 and cathode plate 4
Dust is separated with pole plate, the wind for the wind 8 that the dust in the cavity that gathers dust is formed in electric field force, the wind-force of corona wind 9 and compressed air
Power is superimposed under the force action perpendicular to dust collecting pole plate 3 to be formed and is closed in the cavity, eventually falls into bottom ash bucket 2.It inhales
The dust being attached on 4 outer surface of dust collecting pole plate 3 and cathode plate can also be detached from pole plate under the action of rapping, be formed in three kinds of power
The cavity that gathers dust is entered by the through-hole 31 of 3 outer surface of dust collecting pole plate under force action, is eventually fallen into ash bucket 2, completion was gathered dust
Journey, and drain into outside deduster.Present invention reduces the possibility of reentrainment of dust, greatly improve the efficiency of dedusting.
Finally it should be noted that：Above embodiments are only to illustrate the present invention and not limit technology described in the invention
Scheme；Therefore, although this specification is referring to above-mentioned each embodiment, the present invention has been described in detail, this
Field it is to be appreciated by one skilled in the art that still can modify to the present invention or equivalent replacement；And all do not depart from this
The technical solution and its improvement of the spirit and scope of invention, should all cover within the scope of the claims of the present invention.
