The high-efficiency electric precipitator is capable of reducing secondary raise dust loss, greatly accelerating the migration velocity of charge mill dust, remarkably improving the dust removing efficiency and ensuring the smoke dust emission concentration to reach 20mg/ Nm<3> and below.
Description
Technical field
The present invention relates to a kind of electric cleaner that is used for the purifying industrial smoke dust, make smoke dust discharge concentration reach 20mg/Nm
3And below.
Background technology
At present, known conventional electric cleaner body is to be made up of the individual or more a plurality of conventional electric field series connection of 3-6.In the electric field, polylith positive plate (dust collecting pole plate) constitutes an anode arranged plate (plus earth).Adjacent anode plate row intermediate arrangement is installed corona wire (negative electrode), and constitutes an exhaust gases passes, and each electric field has the dozens of passage.After negative and positive two interpolars applied high voltage and produce corona discharge, charged dust was captured by positive plate and cathode line facing south respectively under the electric field force effect motion of pole plate and cathode line and heavy the collection on it.When dust deposition arrived certain thickness, deashing mechanism work came off dust layer, falls into the bottom ash bucket.Through this electric field flue gas after being purified, enter next electric field and continue to purify, purify the back by last electric field and discharge from the smoke box of giving vent to anger.
But in the conventional electric field, the suffered electric field force of charged dust becomes 90 ° with the flue gas flow rate direction, and flue gas flows along the anode arranged plate horizontal direction, not only influences ash-removal effect, causes reentrainment of dust, simultaneously, the dust characteristic is had stronger sensitiveness.The result causes the decay of electric cleaner efficiency of dust collection, though electric cleaner has a plurality of electric fields, the discharging of flue dust stably reaching standard is still difficult.
Summary of the invention
Technical problem to be solved by this invention be overcome that conventional electric cleaner reentrainment of dust is serious, the deficiency of efficiency of dust collection decay, soot emissions difficulty up to standard; A kind of high efficiency electric cleaner is provided; Can reduce the reentrainment of dust loss; Increase substantially the migration velocity of charged dust, significantly improve efficiency of dust collection, make the electric cleaner concentration of emission can reach 20mg/Nm
3And below.
In order to achieve the above object, the technical scheme that the present invention adopted is:
A kind of high efficiency electric cleaner; Comprise the electric field of one or more mutual series connection, it is characterized in that: said electric field comprises the aeration type anode row who laterally arranges, and corona wire places in the middle of the adjacent anode row; Constitute many exhaust gases passes; Arrival end at the partial fume passage is provided with the mixed type spoiler, at the port of export of partial fume passage the mixed type spoiler is set, and the entrance and exit of each exhaust gases passes has a place to be provided with the mixed type spoiler at least.
Aforesaid electric cleaner is characterized in that: M the exhaust gases passes place continuous at the exhaust gases passes arrival end is provided with the mixed type spoiler, and continuous N exhaust gases passes place is not provided with the mixed type spoiler, and M exhaust gases passes and N exhaust gases passes layout of being separated by; M the exhaust gases passes place continuous at the exhaust gases passes port of export is provided with the mixed type spoiler, and continuous N exhaust gases passes place is not provided with the mixed type spoiler, and M exhaust gases passes and N exhaust gases passes layout of being separated by.
Aforesaid electric cleaner is characterized in that: M=1, N=1.
Aforesaid electric cleaner is characterized in that: M=2, N=1.
Aforesaid electric cleaner is characterized in that: M=3, N=1.
Aforesaid electric cleaner is characterized in that: entablature and vibrating rod are drawn together in the package of said aeration type anode, and the fence bar is arranged between entablature and the vibrating rod, are provided with the rapping anvil in vibrating rod one side.
Aforesaid electric cleaner is characterized in that: said fence bar is a S shape, and is arranged in parallel.
Aforesaid electric cleaner is characterized in that: said fence bar be semicircle in one's ear, and be crisscross arranged relatively.
During the electric cleaner operation, flue gas is discharged after several electric fields purify after getting into from the air inlet smoke box.In electric field, flue gas is N passage entering of opening from passage, because this channel outlet sealing, flue gas turns to, and at a certain angle through anode row, charged dust is arranged by anode and captured, and flue gas after being purified flows out from N channel outlet of the other end.Because M port number value of mixed type spoiler choked flow is different, also inequality through anode row's number behind the flue gas admission passage, its dust collection effect also has nothing in common with each other.Therefore, in practical application, can select the numerical value of M according to different situations.
When the last dust that captures of anode row reached certain thickness, deashing mechanism work came off dust layer, falls into the bottom ash bucket.Dust stratification on the corona wire also carries out deashing through deashing mechanism, to keep the good discharge performance of corona wire.Deashing mechanism adopts the tangential to hammer rapping, top electromagnetic rapping or shifting brush into shape around arm.
The invention has the beneficial effects as follows:
1. reduce the reentrainment of dust loss significantly.
2. can high efficiency capture industrial fumes, smoke dust discharge concentration reaches 20mg/Nm
3And below.
3. simple in structure, cheap, maintenance is convenient with operation maintenance, and operation and maintenance cost is low.
4. be applicable to the conventional electric cleaner upgrading of flue dust qualified discharge difficulty, also be applicable to newly-built electric cleaner Selection and Design and manufacturing.
