Abstract

PURPOSE:To increase the surface area of a dust collecting plate and to carry the dust surely to the position of the plate by constituting the collecting plate as one electrode of many metallic disks which are provided at regular intervals, and forming a liquid film on the surface of the metallic disk. CONSTITUTION:Plural metallic disk 2 are fixed at regular intervals to the same shaft to obtain a rotary disk 1, and the disk 1 is furnished rotatively in a housing 4. The air sucked from an air suction port 6 is passed between each disk 2, and discharged from an air discharge port 7. An ionization part 8 (positive high- voltage electrode) for charging positively particles in the passing air is appropriately provided in the vicinity of the air suction port 6, and a scraper plate 9 is provided between each disk 2. Both side edges of the scraper plate are brought into contact with the surface of each disk 2, and a liquid is coated on the surface of each disk 2 with an appropriate means to form a liquid film always on the surface of each disk 2. Besides, the disk 1 is used as a cathode, and appropriately grounded.

Description

[Detailed description of the invention] ■)...Object of the present invention The present invention relates to an air cleaner using static electricity,
In particular, by configuring the negative pole dust collection plate as a rotary disk in which a large number of metal discs are installed at equal intervals, the surface area of the dust collection plate can be significantly increased, while the rotary disk can be In addition, liquid (for example, a suitable surfactant, water, oil, etc. ) to form a liquid film on each disk surface at all times, which allows particles in the air (mainly While passing between the disks, particles (dust) are attracted to the one-pole disk, but at this time, the surface of the conventional dust collection plate is 1l-j: the particles are only attracted by static electricity and are in an unstable state. However, in the case of the present invention, since it adheres to or adheres to the liquid film, it is characterized in that it can be reliably conveyed by scraping board positioning without fear of falling off.

It )...Structure of the present invention Next, the structure of the present invention will be explained with reference to its embodiments. A plurality of disc discs made of metal discs (e.g. stainless steel plates) are set on the same axis 3 and arranged at equal intervals (e.g. , 5 recessed intervals), a rotary disk l is provided, and the rotary disk l is fixed at
...Installing the housing so that it can be rotated appropriately, and covering the rotor 11 disc L with an appropriate insulating cover S, the air entering from the intake ROM passes between each disc of the rotary disc and then the exhaust lower. For example, an ionizing part (+ high voltage electrode) is installed near the intake port 6 to apply a high voltage to the particles in the air passing through. Many stainless steel fine mg
; i A narrow flat scraping plate 9 is interposed between each disc of the rotary disc l, and its both side edges are brought into contact with the plate surface of each disc; A liquid such as an appropriate surfactant, water, aromatic oil, etc. is applied to the plate surface of each disc of the rotary discs by an appropriate means, and a liquid film 10 is constantly applied to the plate surface of each disc. The rotary disk 1 is used as one pole and is grounded as appropriate or connected to one electrode of a high voltage generator.

ll indicates an exhaust fan.

As the means for forming the liquid level IO, for example, application piece/2
(e.g., non-woven fabric, felt tyranny) is immersed in the liquid tank 13, the liquid is sucked up by capillary action, and the upper part of the same plate/J in a wet state is immersed in the liquid bath 13, and the upper part of the same plate/J in a wet state is immersed in the liquid bath 13.
Applying liquid to the board surface by intervening contact between the parts, or
It is conceivable to directly dip the lower part of the rotary disk 1 into the liquid tank 13 and apply the coating, but this is not the only option and any suitable method is possible.

■) Actions and effects of the present invention In the above configuration, by rotating the 3-exhaust fan //, air enters the air intake ψ from the intake port 6 and flows between the discs of the rotary disc l. At the same time, the rotary disk l is driven to rotate, and a high voltage is applied to the thin stainless steel wire g' between the ionization parts, making the rotary disk l a single pole. When connected to the negative electrode of the high-pressure generator, the particles in the air entering from the intake port 6 are given ten electric charges while passing through the ionization zone, and the particles of each disc of the rotary disc l, which is the next pole, are Although it is electrostatically attracted to the plate surface, at this time, since the liquid film 10 is formed on the plate surface of each disc as described above, the rotary disk lO is attached or adhered to and held by the liquid film 10. It is conveyed to the position of the scraping board 9 by the rotation of.

The scraping plate 9 is located between each disk 2 as described above, and its both side edges are brought into contact with the plate surface, so that the liquid in the liquid film 10 that adheres or sticks to the particles is scraped off and the scraping plate 9 is It flows downward and is appropriately removed to the outside.

4- As described above, the air cleaner of the present invention has (1) a rotary disk constructed by installing a large number of disks on the same axis at equal intervals, which is different from the case where the circumferential surface of a drum is used, for example. , it has the feature of obtaining an extremely wide dust collection area, (11)... In particular, by forming a liquid surface on the plate surface of each disk 1-, electrostatically attracted particles are held and conveyed only by electrostatic adsorption force. Instead, fine particulate matter adheres to or adheres to a highly adhesive liquid film and is transported together with the liquid to the target location, making it possible to collect particles with high precision. In addition, it exhibits an excellent effect in that particles once attached can be transported without falling off and removed together with the liquid.

(iii)...Furthermore, the present invention does not require any consumable parts or replacement parts such as filters, does not require cleaning of the dust collecting plate, and replenishes the liquid for forming a liquid film, which is slightly reduced. It also has the characteristic of being maintenance-free and can be used continuously for a long time.

Figure 1 (a) 7- 1982 patent No. 1194032, title of invention: Rotary disk electrostatic air cleaner 3, relationship with the case of the person making the amendment: patent applicant 4, agent l), The following sentence is added between page 4, line 18 of the specification and 'M l line 9.

[In the housing ψ, the rotary disk l
If it is installed parallel to the straight direction of the air in the passage of air entering from the intake port 6 and being discharged from the exhaust lower, the air will pass straight between each disk unit of the rotary disk l and come into contact with each disk unit surface. Therefore, as shown in FIG. 2, the rotary disk l is installed in the air passage at a set angle (for example, 45 degrees) at an angle.

As a result, when the air entering from the intake ROM passes between each disk unit of the rotary disk l, it always contacts and collides with the disk unit surface, creating a turbulent vortex flow.As a result, particles adhere to the disk unit surface. Efficiency can be greatly improved. 2), the following sentence is added between lines 15 and 16 on page 5.

[At this time, as described above, if the rotor 11 disk l is installed in the air passage with a set angle of inclination, the passing air will definitely come into contact with and collide with the disk surface, which will result in X. Therefore, the adhesion efficiency of particles will be reduced. It can be improved.
