Description
Technical field
The utility model belongs to environmental technology field, relates in particular to a kind of drainage air intake air purifier.
Background technology
In city, air quality has become one of most significant problems of people's concern in recent years, and people are day by day urgent to the demand of cleaned air.
Electrostatic precipitation is a kind of of dedusting method.Dusty gas is separated by electricity during through high-voltage electrostatic field, and grit be combined with anion and is with after upper negative electricity, tends to anode surface and discharges and deposit.In the industry such as metallurgical, chemical in order to Purge gas or reclaim useful grit.Thereby utilize electrostatic field to make gas ionization make dust particles be adsorbed onto the collecting method on electrode.In highfield, air molecule is ionized as cation and electronics, and electronics marches on towards in anodal process and runs into grit, and the electronegative positive pole that is adsorbed onto of grit is collected.Certainly, in recent years by technological innovation, also there is the mode that adopts negative plate control of dust.Factory, power station that to be usually used in take coal be fuel in the past, collect coal ash and dust in flue gas.In metallurgy, for collecting the oxide of tin, zinc, lead, aluminium etc., now also having can be for the dust cleaning and sterilizing product of household.
While adopting electrostatic precipitation, under the effects such as radiation friction, contain a small amount of free ion in air, depending merely on these free ions is impossible make the grit in dust laden air fully charged.General electrostatic precipitator adopts the method for electric charge field and separated electric field unification, and in high voltage electric field, discharge electrode connects the negative pole of high-voltage DC power supply, and dust collecting electrode connects as positive pole, and dust collecting electrode can adopt flat board, also can adopt pipe.
If further improve voltage, the scope of air ionization (corona) expands gradually, and last interpolar air all ionizes, and this phenomenon is called electric field breakdown.During electric field breakdown, flashing electric discharge, short circuit, electric cleaner quits work.In order to guarantee the proper motion of electric cleaner, the scope of corona is unsuitable excessive, generally should be confined near corona discharge electrode.If the electric-field intensity of each point is unequal in electric field, this electric field is called non-uniform electric field.In electric field, the electric-field intensity of each point is all that equal electric field is called uniform electric field.For example, with two dull and stereotyped electric fields that form, be exactly uniform electric field, in uniform electric field, as long as certain any air is ionized, interpolar air just can portion's ionization, and electric cleaner punctures.Therefore in electric cleaner, inhomogeneous field must be set.
In addition, active carbon is a kind of solid carbonaceous of black porous.By timber, xylocarp shell or beast bone etc., through charing, activation, made in early days, after use instead coal by pulverizing, moulding or with uniform coal grain through charing, activate production.Main component is carbon, and containing elements such as a small amount of oxygen, hydrogen, sulphur, nitrogen, chlorine.The specific area of common active carbon is between 500～1700m2/g.Having very strong absorption property, is the extremely wide a kind of industrial adsorbents of purposes.
Universally acknowledged: active carbon is " all-round absorbent ".Expert prompting: active carbon adsorption remove indoor pollution be at present most widely used general, the most ripe, the safest, effect is the most reliable, a kind of method of absorbing material most species.Active carbon, as a kind of good physics, chemosorbent, is more and more subject to people's attention.
Indoor all pernicious gas molecules such as the formaldehyde of high-efficiency environment-friendly active charcoal bag in can absorbed air, ammonia, benzene, dimethylbenzene, radon; eliminate fast decoration odor; even regulation space humidity; for in room, furniture wardrobe, bookcase, shoe chest, footwear, refrigerator, toilet, floor, fish jar, automobile, air-conditioning, computer, office, hotel and public place of entertainment; there is good effect; it is the jinx of formaldehyde, the expert of virus killing.
Due to independent electrostatic precipitation or charcoal absorption, effect is all not ideal in actual use, if both combine, air purification effect can be very good, but at present, the product that not yet has static to be combined to air cleaning with active carbon on market.
