Dust removal method of electrostatic dust removal equipment


Electrostatic dedusting equipment is a method for removing dust particles from air currents by using the electrostatic force generated by high voltage electric field on charged particles. Apply DC voltage high enough to the electrode to form an uneven electric field between the electrodes. Near the discharge electrode The electric field Ie corona electrode is very strong, which generates a corona discharge, ionizes gas molecules, generates a large number of electrons, and migrates to the vacuum cleaner under the action of the electric field. During the migration process, the electrons easily combine with neutral gas molecules to form negative ions. Dust removal method of electrostatic dedusting equipment Dust particles collide with negative ions and attach to negative ions, and the dust particles are negatively charged. The charged dust is driven to the dust collecting pole under the coulomb force of the electric field, and is deposited on the dust collecting pole to realize the dust particles. Separation from air flow.


The electrostatic dedusting equipment dust removal method utilizes Coulomb force to remove dust. Whether the dust particles are coarse or fine, as long as they are charged in an electric field, they can be deposited based on the migration of Coulomb force to the dust collector. Therefore, the electrostatic dust removal method of the present invention High efficiency, good performance of trapping fine dust particles, it is one of the dust removal methods to remove dust particles above 0.05 μm. However, the equipment structure, flue gas velocity and dust properties have a certain effect on the performance of the electrostatic precipitator. At the same time, the electrostatic precipitator has strict requirements for the specific resistance of solid dust particles. The specific resistance of dust particles is usually in the range of 104 ~ 1010ωcm When the specific resistance of the solid dust particles is less than or equal to 104ωcm (too low), secondary dust is easily generated when the dust collector is shaken, resulting in a low efficiency of the dust collector. On the other hand, when the specific resistance of the solid dust particles is greater than When it is equal to or higher than 1010ωcm, the dust particles are not easy to fall off when the dust collector is vibrated, and a porous insulating layer is formed on the surface of the dust collector. When the critical electric field strength is reached, electrode breakdown will occur, forming many small channels full of positive ions. These small channels will emit a large amount of anti-corona charge, resulting in a reduction in the efficiency of electrostatic precipitator.

In recent years, China's electrostatic precipitator technology has developed rapidly. Independently developed advanced electrostatic precipitators, rotating electrode electrostatic precipitators, mobile electrostatic precipitators, roof electrostatic precipitators and other advanced technologies have come out one after another. Researchers continue to study technical problems such as high dust specific resistance and secondary dust. In order to solve the influence of dust specific resistance on dust removal efficiency, the research on low temperature electrostatic dust removal technology is becoming more and more extensive.


In foreign countries, the research of electrostatic precipitator focuses on the capture effect of high and low specific resistance dust. The electrostatic precipitator method uses high intensity ionization, pulse charging, electron beam ionization and other methods to overcome partial discharge. E. Electrostatic precipitator The anti-corona phenomenon caused by the high specific resistance dust layer deposited on the surface of the electrode plate increases the number of charged particles in the dust and improves the dust removal efficiency. An ionizer is installed in front of the electrostatic duster to charge the electrostatic duster to reduce operating costs. Achieve dust removal and desulfurization integration. The coagulation technology developed in recent years is also a kind of pretreatment device. Dust carries positive and negative charges when passing through the channel between the positive and negative electrodes. The agglomeration technology not only has low operating cost but is also not limited by the site.
