Therefore it is not considered as limiting the invention.
Refering to fig. 1, embodiment of the Fig. 2 for high-efficiency and energy-saving type electric precipitator of the present invention, high-efficiency and energy-saving type electric precipitator, including
Cathode line, cathode frame 201 and anode plate, the cathode frame 201 and anode plate have several, alternating parallel arrangement, often
Several cathode lines are provided in a cathode frame 201；
As shown in figure 3, each cathode frame 201 includes vertical beam 202, top beam 203, bottom beam 204 and crossbeam 205, institute
Stating vertical beam 202 has at least two, and the top beam 203 is fixedly connected on the top of all vertical beams 202, and the bottom beam 204 is fixed to be connected
It connects and is connected with crossbeam 205 described at least one between the bottom of all vertical beams 202, the adjacent vertical beam 202, it is two rows of adjacent
201 middle cross beam 205 of cathode frame is not in same level；
As shown in Figure 7, Figure 8, the cathode line includes support tube 101 and prickle 102, and the both ends of the support tube 101 are solid
It is scheduled on cathode frame 201, the prickle 102 is divided into two rows in the axial direction, is separately fixed at a left side for 101 lateral wall of support tube
The top of right two sides, the prickle 102 is equipped with the front tip 103 before being respectively facing and the rear tip 104 after, the paracone
End 103 is greater than maximum spacing L2, best L1 between 101 front and back of support tube to the spacing L1 between rear tip 104
10mm or more；
As shown in Figure 11, Figure 12, the anode plate includes several pieces of anode plate plate bodys 301, and the anode plate plate body is length
Plate shape, the right of the anode plate plate body 301 are equipped with the collection ditch 302 for preventing reentrainment of dust, the collection ditch 302 at hook-type,
Equipped with the opening 303 towards 301 front or behind of anode plate plate body, the left side of the anode plate plate body 301 is position-limited edge
304。
By the way that prickle is distributed in support tube lateral wall two sides by row pattern, prickle is allowed to play corona discharge effect as far as possible, together
When front tip be greater than support tube to the spacing between rear tip before and after between maximum spacing, to avoid support tube to prickle tip
The shielding action of corona discharge makes the corresponding region of prickle wire intermediate supports pipe have corona current, realizes energy-efficient mesh
's.
Adjacent two rows cathode frame middle cross beam is not in same level, in this way, the crossbeam of adjacent two rows cathode frame belongs to
Staggered floor setting, so that the ash-laden gas near a upper electric field cathode frame is in the case where can not be charged, entrance is next
Electric field can be by effectively charged.In addition, the cathode frame crossbeam can effectively collect an electricity nearby since there are electric field forces
The charged dust particle in field.
By original both sides have collect ditch anode plate plate body be changed to be on one side collect ditch another side be position-limited edge, to have
Effect reduces the weight of anode plate, to reduce the weight of installation difficulty, shell support column, reduces cost, while making on one side
For position-limited edge, effectively anode plate plate body can be limited, the position of stable anode plate plate body, it is ensured that anode dust-collecting and vibrating
When anode plate plate body do not shift.
As shown in Figures 2 to 6, particularly for cathode frame, wherein crossbeam 205 in row's cathode frame 201 with it is adjacent
The spacing arranged in cathode frame 201 between its immediate two crossbeam 205 is equal, uniform to keep crossbeam 205 to be distributed
Property, it can produce equally distributed non-corona discharge area in this way, it can also be excessive to avoid regional area electric field strength.
And the length direction of the crossbeam 205 in general cathode frame is all parallel with flow of flue gas direction, can reduce in this way
To the obstruction of flue gas, at the same at the top of every vertical beam 202 can fixed negative pole insulating suspension 206, in order to by cathode frame 201
It hangs up, and cathode line is parallel with vertical beam 202 and is fixed between top beam 203 and crossbeam 205 or crossbeam 205 and crossbeam
Between 205 or between crossbeam 205 and bottom beam 204.
Using corona direction and corona blind area schematic diagram as shown in Figure 6 after this programme, in figure two cathode frames 201 it
Between accompany one piece of anode plate 216, be formed about corona blind area 215 in the crossbeam 205 of cathode frame 201, but use this programme
Afterwards, although there are also corona blind areas, corona blind area, which belongs to, to be uniformly distributed, and even if dust has passed through a corona blind area,
Also corona zone can be entered after leaving corona blind area with flow of flue gas, can't as previous electric precipitator the company of being formed
Continuous corona blind area allows dust to flee from, to effectively raise standard limit of smog release.
As shown in Figure 7 to 10, and for cathode line, the cross section of support tube 101, which can be made, meets above-mentioned requirements
Polygon, class polygon, ellipse etc. are preferably made as ellipse, and oval short axle is directed toward the front-back of support tube, ellipse
Circular long axis is directed toward the left and right face of support tube, this avoid the generation of wedge angle, advantageously reduces air drag, while oval
Shape is also easy to process, as long as the long axis both ends that two rows of prickles 102 are fixed on ellipse can be met above-mentioned condition, eliminates corona
Electric current blind area.
For the ease of the transport and manufacture of support tube 101, support tube 101 can be divided into preceding semicanal 105 with after along axis
Semicanal 106, preceding semicanal 105 and rear semicanal 106 include arc-shaped tube body 107, are combined by preceding semicanal 105 and rear semicanal 106
Cross section is the support tube 101 of ellipse, and in the integrally manufactured connecting plate in the both ends of preceding semicanal 105 and rear semicanal 106
108, preceding semicanal 105 is fixedly connected with rear semicanal 106 by connecting plate 108, while connecting plate 108 can be used to fix prickle
102。
And the fixation of prickle 102 and support tube 101, preferably with plug welding mode, under the premise of guaranteeing bonding strength, also
It can reduce resistance, specifically can open up at least two plug welding holes 109 in the lower part of prickle 102, while right on connecting plate 108
That answers is also provided with plug welding hole 109, is then fixedly connected with prickle 102 by plug welding with connecting plate 108.
Further, in order to reduce influence of the support tube 101 to corona current, the short axle of best 101 cross section of support tube is long
Degree is less than 102 front tip 103 of prickle to the half of spacing between rear tip 104.And in order to keep corona current more uniform, may be used also
It is in the horizontal direction to be staggered on 101 axis direction of vertical support pipe by the two rows of prickles 102 in left and right, and the right and left prickle
102 on 101 axis direction of support tube spacing it is equal.
For 102 body structures of prickle, in order to preferably generate corona current, prickle 102 includes pedestal 110 and mainboard
111, the mainboard 111 is fixed on pedestal 110, and two secondary tips are respectively equipped on the pedestal 110 of 111 two sides of mainboard
112, an advanced bending one is bent backwards in two secondary tips 112, and the front tip 103 and rear tip 104 are arranged at
The top of mainboard 111 forms multiple discharge tips in this way, and discharges towards different directions, not only improves raising corona current
Uniformity can also reduce the generation of source current blind area.
As shown in Fig. 1, Figure 11 to Figure 15, and the specific structure of anode plate is, in order to reinforce the strong of anode plate plate body 301
Degree, is pressed with concave-convex alternate die mould slot 305 on anode plate plate body 301, i.e. a die mould slot 305 to anode plate plate body 301 just
Face is prominent, and adjacent die mould slot 305 is prominent to the reverse side of anode plate, and die mould slot 305 is arranged along stiffening plate plate body short transverse.
