Description
Technical field
The air cleaning unit that dust contaminant particles are excluded using ionization technique is the utility model is related to, it is especially improved
Ionize section and the independently-powered electrostatic dust-collecting device of dust section.
Background technology
Electrostatic precipitation commonly used in the prior art is to make gas ionization using electrostatic field so that dust particles are adsorbed onto electricity
Collecting method on extremely.Electrostatic precipitation air purifier ionizes the gas molecule in air using high-voltage dc, produces
A large amount of electronics and ion, are moved in the presence of electric field force to the two poles of the earth, encounter in moving process dust granules in air-flow and
Bacterium makes its charged, and electrically charged particle is taken exercises under electric field force effect with air-flow point to opposite pole plate, empty under electric field action
Free ion in gas will move to the two poles of the earth, and voltage is higher, electric-field intensity is higher, and the movement velocity of ion is faster.Due to ion
Motion, interpolar forms electric current.During beginning, the free ion in air is few, and electric current is less.Voltage is increased to certain numerical value
Afterwards, the ion near discharge electrode obtains higher energy and speed, when they hit the neutral atom in air, neutral atom
Positive and negative ion can be resolved into, this phenomenon is referred to as air ionization.After air ionization, due to chain reaction, interpolar motion from
Subnumber greatly increases, and shows as the electric current of interpolar, or corona current sharply increases, and air captures into conductor, high strong voltage
Subsidiary bacteria particles, the cell membrane that instant conductive breakdown is made up of protein, reach and kill bacterial adsorption dedusting.
The course of work of electrostatic precipitator is generally divided into two parts：Section and dust section are ionized, ionizes section in the prior art
Merged together with dust section.Due to reasons such as radiation frictions, contain a small amount of free ion in air, depend merely on these freedom
Ion is impossible to make the grit in dust laden air fully charged.Therefore it is so-called ionization section to need by external force, ionization
Section is usually by metal wire superfine one by one, generally tungsten filament and metallic plate, as aluminium sheet forms.The gold under high voltage power supply effect
Belong to line, also known as access high-tension electricity, generally positive high voltage on corona discharge electrode or anode line, on metallic plate or minus plate access ground or with
Opposite polarity high-tension electricity on metal wire, wire and metallic plate polarity of voltage must be opposite.Wire after logical upper high voltage power supply
Non-uniform electric field is formed between metallic plate, under point discharge effect, corona discharge phenomenon, ionization occur metal wire for surrounding
Air in is ionized.Under electric field action, the free ion in air will move to the two poles of the earth, and voltage is higher, electric-field intensity
Higher, the movement velocity of ion is faster.Due to the motion of ion, interpolar forms electric current.During beginning, the free ion in air
Few, electric current is less.
The voltage that electric cleaner reaches spark-over is referred to as breakdown voltage.This voltage spark punch-through is also referred to as arcing
Phenomenon, can be with electric spark and the very ear-piercing sound, and the electric spark temperature of high-voltage breakdown is very high therefore has and causes burning
Hidden danger；Section or dust Duan Junjia are either ionized due to deduster is high pressure, therefore wire and metal in galvanization
Pole piece is ceaselessly as to atmospherical discharges, so deduster exposure is to be easily that to be converted into the oxygen in air smelly in atmosphere
Oxygen.The ozone of low concentration can be sterilized, but concentration Gao Shihui is hazardous to the human body.The household electrostatic formula deduster of present main flow,
It ionizes section and dust section and connected together, and the space between collecting polar plate is in 6mm below mono-, therefore in cleaning dust cleaning case
Shi Feichang is not easy, the easily damaged tungsten filament in cleaning process, and if changing spacing between metal polar plate, so as to can then influence to purify
Effect.
Existing household electrostatic formula air purifier ionization section and dust section connect together, and the space between collecting polar plate exists
Below 6mm, therefore be not easy very much when cleaning dust cleaning case, the easily damaged tungsten filament in cleaning process, between changing between metal polar plate
Away from so as to influence clean-up effect.Even if still being remained through over cleaning on pole piece, black uses vestige, can not wash.And
And there is also following shortcoming for this kind of product：Ion chamber input voltage is continuously increased to pursue purification efficiency, after voltage rise more
Ozone is also easy to produce, is more easy to make air ionization so as to produce phenomenon of arc discharge, generation ozone.With electric spark and it can also ring very big
The very ear-piercing sound.The ozone of low concentration can be sterilized, but concentration Gao Shihui is hazardous to the human body.
