Description

Electronic air purifier

The utility model belongs to air cleaning unit, the self-loopa air cleaning of particularly suitable confined space.

Existing in the market air purifier or air cleaner, nothing more than or anion generator, or the air filter made from filtering material, purification efficiency to air is low, particularly to airborne molecule, smog can not effectively be removed, and can not effectively remove for airborne harmful chemical, peculiar smell.

The purpose of this utility model is the deficiency that exists at existing air purifier, and a kind of electronic air cleaner that adopts three grades of air filtrations to improve dust removing effects of designing, it has removed harmful substances in air and peculiar smell effectively, for people provide a cleaning, comfortable work, living environment.

The utility model is by the prime screen pack, the high-pressure electrostatic precipitation plate, high-voltage dc pulse power, blower fan, rotating vane, casing is formed, characteristics are that the high-pressure electrostatic precipitation plate is made up of auxiliary pole plate, laying dust pole plate and framework, be provided with corona wire between auxiliary pole plate, and the laying dust pole plate is connect high-voltage dc pulse power negative pole and ground connection, corona wire connects the high-voltage dc pulse power positive pole; At the rear of high-pressure electrostatic precipitation plate one active carbon fiber felt is arranged.

The utility model is rational in infrastructure, and udst separation is effective, is applicable to laboratory, automobile, aircraft, office, room etc., to the place that surrounding air is had relatively high expectations, also can be used for air self-purification aseptic, dustless space.

Fig. 1 is the vertical view of a kind of embodiment of the present utility model;

Fig. 2 is the structural representation of the utility model mesohigh electrostatic precipitation plate;

Fig. 3 is the fundamental diagram of the utility model mesohigh electrostatic precipitation plate;

Fig. 4 is the circuit theory diagrams of high-voltage dc pulse power of the present utility model.

In conjunction with Fig. 1, Fig. 2, Fig. 3: the auxiliary pole plate 12-of 1-high-pressure electrostatic precipitation plate 2-active carbon fiber felt 3-prime screen pack 4-high-voltage dc pulse power 5-blower fan 6-rotating vane 7-casing 8-high-pressure electrostatic precipitation plate framework 9-corona wire support 10-laying dust pole plate 11-connects the screw rod that anodal screw rod 13-corona wire 14-connects negative pole

The course of work of the present utility model: after connecting power supply, dirty air by blower fan 5 in the bonnet inhalation machine, remove dust granule bigger in the air and floating dirty foreign material such as fiber through prime screen pack 3 earlier, enter the high-pressure electrostatic precipitation plate of forming by parts such as auxiliary pole plate 11, laying dust pole plate 10, corona wire 13, frameworks 81 again, this plate is a two-period form, laying dust pole plate 10 connects the high-voltage dc pulse power negative pole, corona wire connects the direct current pulse power source positive pole, and air enters the charging area of being made up of corona wire 13 and auxiliary pole plate 11 (the g district among Fig. 3).Air is ionized under the effect of high-voltage dc pulse electricity, wherein anion by corona wire 13 with positive charge neutralization, cation and dust in air, molecules such as bacterium collision contact, make their lotuses that becomes positively charged, the dust granule that these are charged, bacterium inhales under effect of electric field to laying dust district (the h district among Fig. 3), thereby be captured, pile up, bacterium also is killed under the effect of high-voltage electrostatic field, owing to adopt the high-voltage dc pulse power supply, make field operation stable, be difficult for producing ozone, dust is difficult for secondary fly-up, and airborne most pollutants of process high-pressure electrostatic precipitation plate are removed.The third level filter course that air is formed by active carbon fiber felt 2 again, contained harmful chemical in the air, be adsorbed as formaldehyde, benzene, ozone, radioactive substance and peculiar smell and remove, the air of cleaning enters indoor by blower fan 5, rotating vane 6, go round and begin again like this, room air is purified very soon.

In conjunction with Fig. 4, the working power of the utility model mesohigh electrostatic precipitation plate is the high direct voltage pulse power, and circuit is by integrated circuit a, b, c, transistor f, rectifier bridge heap d, power transformer T, pulse booster transformer e and resistance R ₁, R ₂, R ₃, R ₄, capacitor C ₁, C ₂, C ₃, C ₄, C ₅Form.The energising back is by transformer T, and rectifier bridge is piled d, integrated regulator b, c and capacitor C ₁, C ₂, C ₃, resistance R ₃, R ₄To high-voltage dc pulse power provide+12V ,+working power that 15V is stable.Wherein transformer T is a step-down transformer, capacitor C ₁, C ₂, C ₃Be filter capacitor, resistance R ₃, R ₄Forming bleeder circuit makes the voltage of integrated regulator b output certain adjustment can be arranged, integrated circuit a and resistance R ₁, R ₂, capacitor C ₄, C ₅Form multivibrator, get electric back and produce the 18000Hz high frequency electric, this electric current amplifies through transistor f, and again through pulse transformer e, the rectification of boosting obtains the work of 6000V high direct voltage pulsed drive high-pressure electrostatic precipitation plate.

The utility model third level screen pack has used active carbon fiber felt, it is high 30 times that the adsorption capacity of its specific activity carbon granule is wanted, and active carbon fiber felt also has very strong filtering effect to the molecule of air, after it uses a period of time, can activate easily, prolong service life.

External form of the present utility model can be made various difformities.
