Description

The sterilization type aircleaner

The utility model relates generally to electrostatic separation, is the air cleaning facility that a kind of electrostatic separating device combines with solid separating device.

In general room, particularly ward, in the air except that the various dust particles that waving, also containing various peculiar smell, be mixed with a large amount of bacteriums and virus, mainly is carbon monoxide, ammonia, the gas that goes mouldy, staphylococcus aureus, Bacterium prodigiosum, mould, acarid, Legionella, common cold virus and influenza virus etc.The existence of these peculiar smell, bacterium and virus seriously influences people's health, so the cry that an urgent demand improves the indoor air condition is more and more higher.But existing air cleaning facility as various electrostatic precipitator, mostly is can only dedusting and can not sterilize.The Chinese patent communique discloses " electrostatic air cleaner " patent that the patent No. is ZL93226519.7 in 1994, this is a kind of air purifier with honeycomb needle bar shape two-region high-pressure electrostatic field structure, its electrostatic field structure is made up of honeycomb type earth plate and the bar-shaped discharge electrode of light-wall pipe and the needle-shaped discharging electrode that are arranged on honeycomb type earthing pole (also claiming dust collector pole) center with one heart, and scribbles bactericidal agent on dust collector pole.This device can electrostatic precipitation, has bactericidal action again.But in the electrostatic field structure of this device, there is the not high shortcoming of precision in cantilever position in its discharge electrode, makes the utilization rate of electric field lower; And this device just relies on the medicine of coated on dust collector pole to come sterilization, and can not be in order to deodorization and kill virus.So this device still is difficult to satisfy the major requirement that purifies the air of a room.

The purpose of this utility model provides a kind of sterilization type aircleaner with dedusting, deodorization, sterilization effect, making it to be suitable for the various occasions of air cleaning that need uses, particularly be applicable to the place that air cleaning is had relatively high expectations or needed suitably to sterilize, as office, senior house, hospital operating room, ward etc., patients such as asthma, burn, lift face, rhinitis, pneumonia, leukaemia also there are health care and supplemental treatment effect.

Realize in the technical solution of the utility model of above-mentioned purpose, comprise body, centrifugal blower, air filter, high pressure generator and static field device that general air cleaning unit has, static field device in the utility model is a kind of combined static field device, includes the second static place, and the 3rd static place that formed by this first, second static place combination that are constituted and be with the first static place of positive high voltage, constituted and be with negative high voltage by tubular type discharge electrode and barrel type earth plate by fine rule type discharge electrode and cylindrical shell shape earthing pole; Fine rule type discharge electrode and tubular type discharge electrode respectively are positioned on the central shaft of corresponding barrel type earth plate, and its two ends are fixed on the fixed head, are filled with the composite filter from porous type activated carbon and nonwoven fabric of long fibers composition in the 3rd static place.The length of the first static place and the second static place is different, and it depends on bacterium and viral charged time and transit time, and the length of getting the second static place in the utility model approximately is two times of the first static place.For removing airborne carbon monoxide, ammonia efficiently, further remove ozone and other various peculiar smell, the port of export of the utility model in the second static place is provided with the rugosity acf layer.Activated carbon fiber is made rugosity, to increase filter area, reduces filtering velocity.

As everyone knows, negative aeroion is explained to being a kind of air vitamin by U.S..An amount of anion in the pure air has certain health care and medical assistance effect to patients such as hypertension, heart diseases; The ionspray device can improve air quality with the various liquid mists (as clear water, perfume, disinfectant, freshener, treatment soup etc.) of ejection.The air outlet place of the utility model in housing can be provided with anion generator or/and ionspray gas.

Pure qi (oxygen) process of the present utility model is: room air enters from air inlet under the swabbing action of centrifugal blower, at first by filter, and major diameter particles such as elimination hair, fiber, dust; Enter combined static field device then.The first static place of this static field device can make bacterium, virus implement electric-field charge or diffusional charging.This electric field also can evenly produce the ozone of trace because of corona discharge.After charged bacterium, virus enter the composite filter that is filled in the 3rd electrostatic field with air, can be on the hole wall attached to nonwoven fabric of long fibers or porous active carbon because of the effect of image force, on the other hand, long fibre nonwoven is furnished with the electret effect, a large amount of cation and the ozone of meeting absorption, and cation and ozone have significant kill bacteria and viral effect, so just killed by the cation and the ozone of absorption on nonwoven attached to bacterium on the hole wall of nonwoven fabric of long fibers or porous active carbon and virus.Processed thereupon air enters the second static place.This static place is similar to uniform electric field, has higher electric-field intensity, make charged particulate, bacterium and virus in the higher migration velocity of this district acquisition and move to dust collector pole (that is earthing pole), the bacterium of not obtaining electricity can obtain more to obtain motor with virus at this and meet, and accumulates on this dust collector pole; At last, by the rugosity acf layer of further flowing through of the pure air behind dedusting, the sterilization, because of this activated carbon fiber has physics, chemisorbed and catalytic reduction effect concurrently, so can remove carbon monoxide, ammonia, various peculiar smell and remaining excessive ozone further.The air that purifies (first, level V fibrage, middle three grades of static places) through above-mentioned Pyatyi becomes aseptic pure air basically.The anion generator and the ionspray device that are arranged on this device outlet air end can add quantitative anion and increase humidity or an amount of light perfume (or spice) in air.

The utility model has the advantages that, owing to the utlity model has pre-filtering, comprise that Pyatyis such as the combined static field device of first, second, third 3 static places and rugosity acf layer purify, add multiple treatment facilities such as anion generation and ionspray, therefore can utilize multiple methods such as diffusional charging, electric-field charge, positive charge sterilization, ozone sterilization sterilization, activated carbon absorption and spraying, dedusting efficiently and kill airborne bacterium, virus and other microorganism can also be removed carbon monoxide, ammonia and multiple peculiar smell simultaneously efficiently.See that thus the utility model is the protection indoor air environment, the propagation that wards off disease ensures health, and electronic products such as protection computer etc. provide a very effective means.Outstanding advantage of the present utility model is to kill Legionella bacteria, effectively prevents air conditioner disease; Remove archive office, reference room, library, the airborne mould in museum, make document information intact, it can also be for the patient who cures the disease that recuperates at home provides one family aseptic clean environment, for therapy rehabilitation is created good condition.
