Problems solved by technology
[0004] The invention mainly solves the problem of poor dust removal effect caused by the collection of high specific resistance dust and secondary dust raising in the traditional single-zone electrostatic precipitator, and the excessively large volume and complex structure of the dust remover due to too many electric fields in the dust remover. Provides a dual-zone electrostatic precipitator with simple structure, less setting electric field, and separate charging and dust collection

Embodiment
[0025] Example: A double-zone electrostatic precipitator (see attached figure 1 , 2 ), composed of an electrostatic precipitator room and a high-voltage power supply. The electrostatic precipitator room includes a flue gas inlet component 1, a labyrinth air uniformly distributed device 2, a charging electrode plate 3, a charged area discharge corona electrode 4, an I-shaped dust collecting electrode plate 5. Dust collection corona 6, flue gas outlet parts 7, shell 8, ash hopper 9, rapping device 10, dust collection high-voltage power supply 11, charged high-voltage high-frequency power supply 12, the dust removal room is divided into charged area and dust collection Area, such as figure 1 . The dust-containing smoke flow passes through the inlet part 1, the labyrinth air distribution device 2, enters the charging area, and then enters the dust collection area. After purification, the smoke flow is sent into the smoke window by the outlet part 9 for discharge. After the charged ...

The invention discloses a double-region electrostatic dust collector. The double-region electrostatic dust collector comprises a smoke gas inlet part, a labyrinth type gas flow uniform-distribution device, a charged plate, a charged region discharging corona electrode, an I-shaped dust collecting polar plate, a dust collecting corona, a smoke gas outlet part, a shell, an ash bucket, a rapping device, a high-voltage dust collecting power supply and a charged high-voltage and high-frequency power supply, wherein a dust collecting chamber is divided into a charged region and a dust collecting region; a gas flow containing smoke gas enters the charged region via the inlet part and the labyrinth type gas flow uniform-distribution device and then enters the dust collecting region; and after being purified, the smoke gas flow is fed into a smoke window for exhaustion via the outlet part; after the charged region and the dust collecting region are respectively supplied with high voltages, a large amount of ions and electrons are generated through corona discharge of the charged region, so that the passed particles are substantially provided with saturated charges; in the dust collecting region, the transverse I-shaped polar plate is used for depositing the charged particles on the polar plate by means of comprehensive action of an electrostatic force and an inertia force; and through rapping dust into the ash bucket, the smoke gas containing dust is purified.
Description
Technical field [0001] The invention relates to a flue gas dust removal device, in particular to a double-zone electrostatic precipitator. Background technique [0002] Electrostatic precipitator is one of the most used devices for the purification of flue gas particles, and has been widely used in flue gas dust removal and purification treatment in various industries. The electrostatic precipitator has the advantages of a large particle size range and high dust removal efficiency. However, the conventional single-zone electrostatic precipitator with the dust collecting electrode plate in the same direction as the airflow has anti-corona phenomenon for some flue gas with high temperature and high specific resistance. The secondary dust generated during dust removal is serious, resulting in a decrease in dust removal efficiency; in addition, electrostatic dust removal affects fine particles ( <PM2.5) is difficult to effectively remove, and these fine particles pose serious harm...
