Abstract

The utility model provides an electrostatic air purifier. In the electrostatic air purifier, the main structure of the electrostatic field of the electrostatic air purifier is formed from the series connection of more than two narrow-space beehive needle rod two-region electric fields. The dust collection of the electrostatic field is coated with long-acting sterilizing agent which can kill bacteria in the air. An activated charcoal filter can filter out the toxic and harmful gas in the air. The utility model which can replace ultraviolet or other germ filtering equipment can be suitable for various sterile situations; meanwhile, the utility model has all the functions of the air purifier, such as dust removal, abnormal smell removal, negative ion generation, etc.

Description

Staticelectricity air purifier

The utility model relates to a kind of electrostatic air cleaner, particularly a kind of air purifier with kill bacteria, electrostatic precipitation.

Existing air purifier generally has smoke abatement, takes off peculiar smell, removes effects such as bacterium and anion generation, but does not all have the function of kill bacteria.In the air that pollutes, anion absorption or cohesion dust, bacterium form the anion of attaching most importance to, and be harmful unhelpful.

United States Patent (USP) 4,629,482 adopt the HEPA high efficiency particulate air filter, and the bacteriological filtration ability of its start after 2 hours is 92.4%, but do not have sterilizing function, and still might be backflowed by the bacterium of elimination enters air.

The purpose of this utility model is but that a kind of air purifier that not only can kill airborne bacterium but also electrostatic precipitation will be provided.It is applicable to security institute, dining room, dance hall, computer floor, hotels and other places, makes in the air in these places bacterial content less than state health standards GB9663-9672-88.Be applicable to that also hospital operating room, pharmacy, electronics, optics, Food Monitoring, epidemic prevention etc. require cleanliness factor to reach 10,000 grades clean environment.

Task of the present utility model is achieved in that indoor air enters from air inlet, at first by electrostatic pre-filters, removes dust.Enter the electrostatic sterilization device that is in series by three thin space honeycomb needle bar two-region electric fields then, the long-acting bactericidal agent of coated on the electric field dust collection plate, in three hours the bacterium that traps approached 100% kill, the wind speed of thin space honeycomb needle bar two-region electric field is 2.8m/s, average field-strength is 8Kv/cm, effectively the holdup time is 0.028s, thereby avoids bacterium to return to the possibility of air-flow.Enter the immersion-type active carbon filter at last, eliminate Co, NH ₃, O ₃And various peculiar smell.The high-frequency and high-voltage constant current safety switch power supply supporting with it is when load variations, and the variation of its high pressure output current is less than 5%, thereby assurance electric field trouble free service does not produce ozone and sparking.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Embodiment

The cabinet-type electrostatic air cleaner mainly is made up of air inlet 1, the two air intake centrifugal machines 2 of low noise duplex, 120w power switch power supply 4, high-frequency and high-voltage constant current safety-type Switching Power Supply 3, electrostatic pre-filters 5, high-pressure electrostatic electric field 6,7,8, immersion-type active carbon filter 9, appliance controling plate 10, infrared sensing switch 11, anion generator 12 and air outlet 13.

Wherein the structure of high-pressure electrostatic electric field 6,7,8 all is identical, is honeycomb needle bar shape two-region electric field structure.Dust collector pole shell (14) and negative electrode fixed head 16 all are by the ABS plastic injection molded, and honeycomb dust collector pole sterilization pole plate 15 is shaped by the thick aluminium alloy punch die of 0.3 μ m, then its welding are positioned among the dust collector pole shell 14.Each electric field has 94 honeycombs, and 94 discharge electrodes are correspondingly just arranged.The bar-shaped discharge electrode 17 that discharge electrode is made of the brass light-wall pipe with φ 8mm and form by the needle-shaped discharging electrode of making through rounding technology with φ 0.7mm stainless steel 18.Is connected with the long brass bar of 5mm between bar-shaped discharge electrode 17 and the needle-shaped discharging electrode 18, passes through the hot cover process close-fitting between their trisomes and form.Reinforce with binding agent between discharge electrode and the negative electrode fixed head 16, be linked to be path with the welding of φ 0.6mm bare copper wire then.

In room air, be mixed with a large amount of pollutants, when mainly containing meal dirt, cigarette smoke, bacterium, virus, carcinogen, toxic and harmful, open power switch power supply 4, room air enters from air inlet 1, arrive static pre-filtering 5 and filter out meal dirt, as hair, fiber, dust etc.Entering high-voltage electrostatic field 6,7,8 three electric field cascaded structures then can make each electric field be operated in optimum state respectively.6th, 7 electric field energies make fine aerosol be condensed into meal dirt.Honeycomb needle bar two-region three electric field structures have very big dust suction surface area, can efficiently remove smog in the air, respirable dust, bacterium, virus and carcinogen.Scribble long-acting fungicide on the dust collector pole sterilization pole plate 15 of electric field, avoid that bacterium and virus are assembled, procreation, in three hours the bacterium that traps approached 100% kill thereby can kill the bacterium, the virus that are captured by electric field rapidly.At this moment, the wind speed of thin space honeycomb needle bar two-region electric field is 2.8m/s, and average field-strength is 8Kv/Cm, and effectively the holdup time is 0.028s, thereby avoids bacterium to return to the possibility of air-flow.Enter immersion-type active carbon filter 9 at last, the immersion-type active carbon has the effect of chemistry, physical absorption and catalytic reduction concurrently, to purifying Co, NH ₃, O ₃And the effectiveness of eliminating peculiar smell is fairly obvious.The pure air that comes out from immersion-type active carbon filter 9 enters anion generator 12, and in the air of cleaning, light anion plays the effect of air vitamin.Pure and fresh air is directly delivered to indoor every nook and cranny by blower fan power from the air outlet 13 on top, thereby realizes air cleaning.
