Description
Technical field
The present invention relates to a kind of wet cottrell moisture film forming apparatus, belong to mechanical field.
Background technology
Electric cleaner is that one curvature of placement is comparatively small (tapering) between higher curvature (plane) dust collecting electrode
Discharge electrode, then applies high voltage in discharge electrode, and unbalanced electric field is formed between discharge electrode and dust collecting electrode.Intensive electric field
Line, the corona (corona) occurred using the enhanced discharge electrode end points (spray point) of electric-field intensity discharges, and makes the grain of inflow
Sub- state material (dust, mist) is powered, and charged particle moves to dust collecting electrode by electrostatic force and adsorbs and remove in continuous electric field
Device.
0.1~1 μm of sized particles of diameter are in the case of with common mechanical formula deduster, and its dust removal method is by inertia
What power was dominated, dedusting purpose is unable to reach because particle is too small, in the case of scrubbing tower dedusting, its dust removal method is mainly use
Extension, because particle can not meet greatly very much dedusting purpose, can not possibly be realized efficient using common cleaner in a word
Dedusting.But electrostatic force acts on relatively large for the particle of 0.1~1 μm of size of diameter, for handling less than 1 μm fine
Particle is especially suitable for.The wavelength of visible rays is 0.38~0.78 μm, so once the particle of 0.1~1 μm of size is discharged greatly
During gas, there is white cigarette phenomenon in the excessive scattering of visible rays, the big reason complained as people.Utilize this electrostatic force dedusting
Device be exactly electrostatic precipitator, electrostatic precipitator is divided into dry type and wet type two according to the mode difference for removing dust collecting electrode dust
Kind, dry electrostatic cleaner is that the dust for setting rapping apparatus to will be attached in dust collecting electrode removes, and wet cottrell is logical
Cross intermittency mode to be cleaned, traditional mode has：Intermittence injection and fine liquid (vaporific) continuously spray.For dimension
Holding cleaning efficiency needs huge water flow, and is difficult to clean electrode comprehensively, it is necessary to periodically carry out stop cleaning；With fine
Liquid (vaporific) is continuously all evaporated in the case that sprinkling is cleaned to almost all of moisture during electrode front end, electrode interior
Depths has no idea to get effective washing, if hypervolia also can reduce efficiency because of spark discharge during sprinkling.
The dust that dust collecting electrode is collected is mainly non-conductor, if cleaning will form dielectric film in dust collecting electrode not in time, is hampered
Hinder discharge electrode smoothly to discharge, spark discharge is induced by minor insulation breakoff phenomenon, this is reduction electric cleaner operating efficiency
Principal element.Therefore the dust catching efficiency for improving electric cleaner in the long run essentially consists in the cleaning for keeping dust collecting electrode.
