Description
Technical field
The present invention relates to a kind of filter, relate in particular to a kind of constructure ventilation air-conditioning system highly effective air electronic filter.
Background technology
The time of one day life of modern about 80% is spent indoor.The air quality of indoor environment directly influences people's healthy and operating efficiency.Modern building is equipped with central ventilation and air conditioning system, yet present most ventilation and air conditioning systems lack effective filter, cause the ventilation and air conditioning system severe contamination, and these dirty systems good breeding ground of bacterium, mould, virus just.Along with the raising of expanding economy and living standard, people are to the indoor air quality in the building, and the energy consumption of keeping indoor air quality has proposed more and more higher requirement.Recently, during China and world's the SARS epidemic, nation-building portion, the Department of Science and Technology and the Ministry of Public Health unite the emergency measure of having assigned about the safe handling of constructure ventilation air-conditioning system.The filter of constructure ventilation air-conditioning system is as the important means of improving indoor air quality, prevent disease propagation, and its importance has caused the common concern of government and industry circle.Healthy for the protection people, wait in expectation a kind of birth of more effective, more economical filtration means of people.
At present, the ventilation and air conditioning system of building is normal to adopt traditional filtrate formula to filter means, comprises elementary, middle and high three-stage filtration.Normal bigger first effect or the middle effect filtrate formula filter of energy consumption that adopt in the less demanding building of lustration class, and these filters generally can only filter the air suspension more than 1 micron, and the air suspension of submicron order (particle diameter is 0.001 micron to 1 micron) is difficult to filter, and the air suspension of these submicron orders (as smog, bacterium, virus etc.) exactly the harm to human health and environment is bigger.A kind of electronic air filter more and more causes the attention of industry circle, conventional electronic air filter is as a kind of filtration means of central ventilation and air conditioning system, adopt electrostatic absorption principle, by air is carried out high pressure ionization, allow electric charge on the airborne particulates band, when charged suspended particulates are flowed through the heteropolarity dust collecting electrode, be collected.Conventional electronic air filter often adopts two-region (ionized region, accumulation area) electro static filtering principle, and as shown in Figure 1, through current-sharing, prefiltration net, bulky grain thing (as leaf, bird etc.) is stopped at this dust-contained airflow earlier.Then dust-contained airflow is through ionized region, distinguish air by (8～12KVdc) ionization of non-homogeneous high voltage electric field at this, form a large amount of negative ions, owing to adopt the positive corona utmost point, the negative aeroion that is ionized flows to the just dizzy utmost point and is neutralized, the remaining cation in most of zone in the electric field, airborne grit and cation collision are by the lotus that becomes positively charged.Then, the grit of positively charged flows to accumulation area, and this district is made up of positive and negative staggered parallel plate electrode, and (4～6KVdc), because the same sex is repelled each other, there is a natural attraction between the sexes, and the positively charged grit is adsorbed on the negative plate, thereby reaches filter effect approximately for voltage across poles.
Air suspended particulates charged mode in high voltage electric field comprises electric-field charge and diffusional charging dual mode.Air is separated into a large amount of cations and electronics in high voltage electric field, electronics is shifted to the just dizzy utmost point and is neutralized thereon, and cation is done in the well-regulated motion process under electric field action, when running into neutral suspended particulates just attached to top, make the suspended particulates positively charged, Here it is, and first kind of charged mechanism is electric-field charge.Secondly, cation not only moves under electric field action, and also has warm-up movement, and cation is attached to suspended particulates and makes particulate charged in the warm-up movement process, then be that second kind of charged mechanism is diffusional charging.According to the static theory, electric-field charge mainly works for the particulate more than 1 micron, and for mainly relying on diffusional charging to work less than the particulate below 0.2 micron, for 0.2～1 micron particulate, then electric-field charge and diffusional charging work simultaneously.For the particulate more than 1 micron with square being directly proportional of charge number and its particle diameter, mean particle dia is big more, the charged quantity of particulate is big more, the effect that particulate is collected is good more.For the particulate below 1 micron, because the effect of diffusional charging makes its charged number bigger than what calculate.Studies show that for the particulate below 1 micron, the charged several n that obtain because of the diffusional charging effect are stable with ratio (n/Dp) maintenance of its particle diameter Dp, in the time of can not causing particle diameter Dp to reduce, charged several n obviously reduce.When charged particulate enters positive and negative accumulation area staggered, that is made up of parallel plate electrode, under the Coulomb force effect of uniform electric field, on the collecting plate of heteropolarity, move and sink and collect.When particulate is done transverse movement in the accumulation area electric field, be subjected to the resistance of air, when Coulomb force equals air drag, the external force sum that acts on the particulate equals zero, like this, particulate is laterally moving at the uniform velocity, and this moment, the movement velocity (W) of particulate was called migration velocity (or separating rate).Migration velocity is big more, and the effect that particulate is collected is good more.
Therefore, for set particulate group, when other conditions were constant, particle diameter was big more, and migration velocity is big more, and filter effect is good more; And particle diameter is more little, and migration velocity is more little, and filter effect is poor more.According to the electronic air filter of Beijing Kangfu Environment Control Co research and development examining report, also meet above-mentioned rule at national air-conditioning equipment quality supervision and test center.The testing result of different-grain diameter classified counting efficient is as follows:
Sequence number particle diameter (micron) counting efficiency (%)
1 0.3 81.8
2 0.5 84.1
3 1.0 98.2
4 2.0 99.4
5 5.0 100
As can be seen: when particulate its filter efficiency more than 1 micron the time satisfied, when particulate below 0.5 micron the time, its filter efficiency is unfavorable.And smog, bacterium, virus stick to the particle diameter of airborne suspended particulate substance, about about 0.01 micron to 1 micron (as its particle diameter of present SARS virus greatly about about 0.01 micron) promptly can not guarantee smog, bacterium, virus are given high efficiency filter greatly.The existing electronic air filter of being researched and developed both at home and abroad all is to adopt above-mentioned dual zone type electro static filtering structure.That existing electronic filter is used for is civilian, during the industrial building ventilation and air conditioning system, compare with traditional filtrate formula filtration means, though the filter quality that can be greatly improved, still smog, bacterium, the virus in the filtered air efficiently.Also can illustrate from above-mentioned examining report: the air-borne particulates diameter is more little, and filter effect is low more.Therefore, this dual zone type electronic filter is to handling the micron-sized suspension in the air Central Asia (as smog, bacterium, virus etc.), though certain effect is arranged, filter efficiency is high not enough, can't fundamentally improve IAQ, improves indoor air quality.How making the electronic air filter improve filter efficiency, with the micron-sized suspension in the filtered air Central Asia (as smog, bacterium, virus etc.) effectively, is an important topic of industry scientific research.
