Abstract

The utility model discloses an air purifying device which is used by two-stage polarization pots connected in series, and the polarization pots are filled with glass fiber. The positive and the negative electrode in the polarization pots are connected with a high-frequency and high-voltage generator. When the air passes through the utility model, the dust, the bacteria, and the micro organisms in the air can be absorbed on the glass fiber, and all the bacteria and the micro organisms are killed, achieving the super purification of the air. The utility model has the advantages of simple structure, low cost, strong practicality, high air purification rate, wide application, and high purification purity.

Description

Electronic super-pureness air purifier

This utility model is a kind of air cleaner.Be applicable to electronics industry, semiconductor element and pharmacy, microbial fermentation, plant tissue and cell liquid culture, health care, aspects such as national defence scientific research are specially adapted to big-and-middle scale, super large-scale integration production.

At present, clean room, superclean bench, the required filtrated air of fermentation engineering all are the modes that adopts the passive type filter both at home and abroad.The shortcoming that this mode purifies air is: if the structure of medium is excessively tight, though can play the purity that improves air cleaning, the resistance that air is passed through is too big, and the wind screen is too little.If the structure defective tightness of medium, dust, antibacterial just might pass through, can not reach the effect of air high purification, if adopt electrostatic filtration can produce ozone again, because aeroscope is not high when production, operation, cause many electronic products (element) will lean on external import, influenced the development of high-tech such as China's electronics, national defence, space flight and biology.

The purpose of this utility model is exactly in order to overcome the problems referred to above, and a kind of electronics ultra-pure purification air assembly is provided.

Technical solution of the present utility model is to adopt air pump that air is squeezed into polarization jar air inlet, and the polarization jar is fixedly formed by screw rod and clamp nut by sealing hollow vessel, upper end cover and bottom end cover.Rubber gasket is equipped with in the junction between upper and lower end cap and the tank body.To strengthen the sealing effectiveness of polarization jar, upper and lower end cap and tank body are to make of nonmetallic materials.Be covered with glass fibre in the polarization jar.In order to the dust in the absorbed air.There are a positive electrode plate and a negative electrode plate in the middle part in the polarization jar.Anelectrode on the positive electrode plate is drawn from upper end cover, the negative electrode of negative electrode plate is drawn from bottom end cover, positive and negative electrode is received the outfan of high-frequency and high-voltage generator, when high-frequency and high-voltage is connected, the polarization jar interior highfield that produces, glass fibre shows positively charged when highfield polarizes, at this moment air enters from air inlet, highfield just can be airborne dust grand slam, and kills airborne all antibacterials, microorganism, thereby reaches the purpose of ultra-pure purification air.

This utility model is simple in structure, with low cost, air cleaning rate and purification based on very high purity, and use wide, practical.

Fig. 4 is this utility model high-frequency and high-voltage generator electrical schematic diagram.

Below in conjunction with the embodiment explanation, as Fig. 3, this utility model uses with a secondary polarization jar series connection, best results, when air is squeezed in the air inlet 9 of first order polarization jars 14 by air pump 13, first order polarization jar 14 can all adsorb the dust more than the 0.5 μ m, when the air after first order polarization jar 14 processing is sent in the air inlet 9 that is directly inputted to second level polarization jar 15 from its air outlet 10, second level polarization jar 15 can all adsorb the dust of 0.3～0.5 μ m, and kill airborne all antibacterials and microorganism, from second level polarization jar 15 air of sending is exactly filtrated air, thereby reaches the purpose of ultra-pure purification air.The positive and

negative electrode

7,8 of the first order, second level polarization jars 14,15 all is connected with high-frequency and high-voltage generator 12, its high-frequency and high-voltage generator 12 as shown in Figure 4, the 220V civil power is via mains transformer B ₁, bridge rectifier ZLQ and capacitor C ₁, C ₂The smoother DC voltage of forming of current rectifying and wave filtering circuit output is supplied with oscillating circuit, and oscillating circuit is by full parallel transistor BG ₁, BG ₂, line output transformer B ₂And B ₃Elementary L ₁, L ₂And L ₄, L ₅And resistance R ₄, capacitor C ₃The common composition, oscillating circuit is transformed into the low-voltage AC of certain power with low-voltage dc voltage, supplies with line output transformer B ₂And B ₃, make line output transformer B ₂And B ₃Secondary L ₃And L ₆On high frequency (5KHz) high pressure (1.5～1.7 ten thousand volts) alternating current that all output phase is identical, line output transformer B ₂Secondary L ₃The high-frequency and high-voltage of last output is through diode D ₅, D ₆Deliver on the positive and

negative electrode

7,8 of first order polarization jar 14 line output transformer B behind all wave rectification ₃Secondary L ₆The high frequency voltage of last output is through diode D ₇, D ₈Deliver on the positive and

negative electrode

7,8 of second level polarization jar 15 light emitting diode D behind all wave rectification ₁, D ₂And resistance R ₂Form failure indicating circuit, when high-frequency and high-voltage generator 12 internal circuit break down, light emitting diode D ₁, D ₂Bright, show that circuit breaks down, light emitting diode D ₃, D ₄And resistance R ₃, R ₄Form the under-voltage indicating circuit of high pressure, when polarizing voltage is not enough, light emitting diode D ₃, D ₄Luminous, indicate the clean-up effect of polarization jars 14,15 indirectly, so that regulator potentiometer W at any time ₁, guarantee that polarizing voltage is normal.After the positive and

negative electrode

7,8 of polarization jar connected high-frequency and high-voltage, then the polarization jar glass fibre 4 of positive plate more than 5 was nonpolarity.Glass fibre 4 near positive plate 5 parts is positively charged, the glass fibre 4 of negative plate below 6 is also nonpolarity, glass fibre 4 near negative plate 6 parts is electronegative, and just, negative two-plate 5, glass fibre 4 between 6 is positively charged under electric field action, when air passes through the polarization jar, because airborne dust, antibacterial and microorganism all have polarity, then positively charged dust, antibacterial and microorganism are filtered through glass fibre 4 earlier, absorption in most of nonpolarity glass fibre 4 that is repelled its top by positive plate 5, minority is by near 4 absorption of the glass fibre the negative plate 6, electronegative dust, antibacterial and microorganism just then are being sucked into, negative plate 5, in the positively charged glass fibre 4 between 6, because the polarization jar just, negative electrode 78 meets high-frequency and high-voltage (5KHz, 1.5～1.7 ten thousand volts), two-plate 7, electric field frequency per second conversion between 8 20,000 times.It makes airborne antibacterial and microorganism move back and forth in glass fibre 4 with electric field frequency.Thereby all killing bacteria and microorganisms guarantee the air high purification of sending.
