It is a kind of that there is adaptive and self-cleaning function electrostatic precipitator
Technical field
It the utility model is related to air-treatment field of purification, and in particular to a kind of with adaptive and self-cleaning function quiet Electric dust collector.
Background technology
Current air pollution is on the rise, and seriously endangers the quality of life and health of people.Consumer is for cleaning The requirement of air is further strong, improves IAQ, purification air, removes peculiar smell, removes germ, is increasingly becoming a kind of compel The demand cut, for central ventilation system so as to increasingly popularizing, people are automatic for the air purifier that is used in VMC The requirement of change degree and function also more and more higher.
The air purifier in VMC is mainly based on conventional air cleaners on the market at present, with high efficiency filter formula The particulate pollutant that consumptive material (HEPA filter) came in air filtering, according to the quality of air quality, some cycles just need more A high efficiency filter formula consumptive material is changed, extra burden is virtually added to consumer.With the development of technology, type non-filtering Air purifier arises, and the air purifier of type non-filtering mainly uses high pressure electrostatic precipitation technology, can effectively remove The fine particle pollutant such as PM1, PM2.5, PM10 in air.The principle of electrostatic precipitator technology is as shown in figure 1, be voltage in figure With the ionization current graph of a relation of air, in curve ab sections:Gaseous conduction is only by means of original a small amount of free electron in gas;It is bent Line bc sections:Interpolar conductive current has almost no change, and illustrates electronics and the ion participation conduction not ionized out newly, increased electricity Pressure mainly improves the kinetic energy of original free electron;Curve cd sections:A) when voltage is increased to c ' points, due to the electricity in gas Son has obtained enough kinetic energy, it is sufficient to and the gas neutral molecule for making to collide therewith ionizes, and produces new electronics and cation, New electronics and ion participate in conductive;B) the so-called electron avalanche in gas ionization:When electronics obtain in the electric field it is sufficiently large After kinetic energy, and make its ionization with the collision of other neutral gas molecules, new caused electron number and number of ions are pressed as " snowslide " Geometric progression increase, in population caused by this section up to 100,000,000/more than cm3;Curve de sections:If the voltage liter of two interpolars To e ' points, because corona expands, cause to produce spark or electric arc between electrode, illustrate that interpolar gas is all breakdown.Spark discharge When, voltage across poles drastically declines, while passes through substantial amounts of electric current within the extremely short time.Electric cleaner should often be kept when running Not exclusively breakdown corona discharge state is in the gas of two interpolars, avoids producing short circuit phenomenon as far as possible.Before breakdown Corona state is the optimum state of dedusting, and air handling system uses positive corona pole.High pressure generator needs automatic detection to hit Voltage is worn, and controls high pressure being slightly less than breakdown voltage.We term it adaptive voltage control system.
