Electrostatic precipitator is the cleaner for being come out the dust in gas or drop separation using electrostatic force (Coulomb force),
Also referred to as electric cleaner, cottrell.Electrostatic precipitator obtains in the industry such as smelting, cement, coal gas, sulfuric acid, papermaking, coal-burning power plant
Extensive use is arrived.Distinguishing feature of the electrostatic precipitator compared with other types deduster be：Almost to various dust, smog
Deng until subparticle has high efficiency of dust collection；It can also be applied even if high temperature and high pressure gas；Equipment crushing is small；Energy consumption is low；
Safeguard and maintenance is all relatively simple；Operating cost is low.In view of its advantage is numerous, and with the equipment requirement of coal-burning power plant extremely
Match somebody with somebody, so electrostatic precipitator technology is introduced into after the country, become the standard configuration equipment of vast coal-burning power plant.There is substantial amounts of section
Grind, school, enterprise are directed to the correlative study of electrostatic precipitator, promoted the application development of electrostatic precipitator.But electrostatic removes
Dirt device is very limited for fine particle removal ability, still has a large amount of fine grained flying dusts to enter environment after electrostatic precipitation, causes dirt
Contaminate and influence human health.Reason is that fine particle flue dust composition is mostly osmanthus mistake matter mineral, and its high specific resistance characteristic causes
Removal efficiency is low, and the ＂ secondary droplets ＂ problems that mechanical vibrator triggers, all causing flying dust can not be trapped by electrostatic precipitator completely,
And disadvantages mentioned above is also exactly the problem of flying dust recovery system is difficult to overcome in biomass boiler dust pelletizing system.

Plate is fixed on the support plinth in flue and is electrically connected with high voltage package.
The electrode group plywood is Carbon fibe conductive electrode plate or metal electrode board.
Described secondary combustion chamber is provided with backboard, and air inlet is provided with backboard.
The beneficial effects of the utility model are：
The utility model coordinates negative high voltage electrostatic precipitation filter screen, so as to realize to entering by designing brand-new air channel structure
The flue gas for entering flue is first filtered, then carries out effective second-time burning；Flue gas has not only been purified, while has prevented dust and cotton-shaped
Thing influences the service life of boiler, and electrostatic filter screen is realized to the effective net of the pollutants such as dust by electrostatic precipitation and laying dust filter screen
Change；Electrostatic filter screen includes three layers, bulky grain dust in air etc. tentatively can be filtered, to improve electrostatic precipitator
With the service life of filter screen.
Brief description of the drawings
Fig. 1 is overall structure figure of the present utility model.
Embodiment
The utility model is described further below in conjunction with the accompanying drawings.
As shown in figure 1, the circulating direction of flue gas is shown in arrow, the utility model includes boiler flue 1, secondary combustion chamber
2nd, tail gas control system 3, trough plate 4 is installed in described boiler flue, it is straggly to be placed in boiler flue both sides, boiler flue
The pipe connecting secondary combustion chamber made by alumina material, burning-point 5, secondary combustion chamber and tail gas are provided with second-time burning room
Control system connects, and tail gas control system includes three sections of condenser pipes 6, a filtration system 7, described filtration system by
The three-level filter screen for being connected with electrostatic is formed.The utility model is provided with trough plate by brand-new Flue duct design in flue, first
