Korean Patent Laid-Open Publication No. 2001-24170 discloses a rotatable shaft, a disk radially mounted on the shaft, and the disk rotating into a pool containing a lower cooling liquid to blow air into the pool, and a cooling liquid attached to the disk when rotating. Is an evaporative cooler that exposes the air so that the cooling liquid evaporates from the air and the cooled disk and the remaining cooling liquid flow back into the pool.

German Patent No. 44608 describes an apparatus in which an insulator is located in the gas stream, the disk surface acting only partially as the dust collector surface and the cleaning of the disk occurs in the gas flow, and cleaning of the electrode is also described in British Patent No. 987220. And gas flow is carried out in a single stage apparatus known from Swiss Patent No. 403722, and a single stage apparatus is described in US Pat. No. 3,929,436, wherein a rod or cage type ionization electrode is radially directed into the disk passage. In addition, US Pat. No. 4,000,994 discloses a device in which cleaning means are disposed between protective plates installed transversely to a gas flow and a gas flow is formed so as to flow through a passage formed between the plates in an upper portion. There are also electro-gaseous separation means that can also interfere with ionized particles in the separation zone. A technique is described in which a plate is disposed radially with respect to a rotational axis and does not include a voltage transfer electrode and rotates laterally in a main gas flow direction. US Pat. No. 2,663,380 describes a portion of a gas induction portion of a lower half of the disk. It is prevented by the plate flowing into the lower part and is not placed in the gas flow, and the air gap insulation between the disc and the plate is disturbed during operation because of the insulation between the disc and plate of the ionizer and the disc and plate of the rotating shaft area. Techniques are disclosed, such as the direct exposure and the risk of impurity accumulation and the resulting electrical discharge, in particular in the region of the axis of rotation.

The conventional electrostatic apparatus through the electrode has a dust collecting surface that rotates in the gas flow direction and is operated in one step, and at the same time, since ionization of dust particles contained in the gas occurs in the passage between the disks, it must be cleaned. There has been a problem that requires a device.

In order to solve the above problems, since the present invention does not use an electrode, no static electricity is generated, and since there is no phenomenon in which dust is accumulated in the disk, no cleaning device is required, and the gas is generated by the frictional force of the gas flowing in the disk. The dust contained in the flowing gas is moved to the outer edge of the disk by the difference in specific gravity, and the dust is discharged by the dust outlet formed at one side of the case, and the clean gas is discharged through the exhaust pipe. The purpose is to provide a flag.

In general, when rotating a plurality of disks, the gas flows along with the rotating disk and the disk rotating by static electricity. This phenomenon has been felt a lot in the air flow (wind occurs) in the direction of the CD rotation when running the audio CD play.

The operating principle of the present invention is to use centrifugal acceleration. This centrifugal acceleration affects airflow and the particles contained in it when air is circulated through the multi-disc, and according to the principle of the disc, it uses viscous friction and adhesive boundary layer generated on the surface of the rotating disc and the transverse wall of the body. will be.

If the distance between the disks is less than the thickness of the boundary layer resulting from thin slices, the gas between the disks will rotate with the disks. And centrifugal force is generated to move the particles to the disk outer wall.

Therefore, in the present invention, the distance between the disks is 1 to 30 mm, and preferably 5 to 10 mm is the most ideal distance.

Particles are moved by the centrifugal force and the transverse walls 9 of the main body case 1 Moving to the outlet 7 along the lateral wall 9, and the particles discharged through the outlet 7 enter the tube 6 with some gas generated from the boundary layer and then collect the dust 8. Gas is purified through the exhaust pipe (3) and the pipe (not shown) connected to the exhaust pipe (3), and the gas is transferred to a space of 1 to 30 mm in the original disk and closed in a device that is continuously rotated in this way. It is a principle to remove the dust contained, and to remove the dust of the gas without a separate device.

Compared to a cyclone, the present invention has the advantage that the gas rotation speed is high in the rotor, and therefore, the centrifugal force on the influence of the particles is large.

Therefore, the present invention can not only separate lighter particles and smaller particles, but also remove small particles in the air. In the present invention, several outlets (7) are provided in the side wall (9) to blow out the air of the particles and the boundary layer, and the gas which discharges relatively clean gas is less than 20% of the total gas, and the gas containing impurities is made of cloth. Purified using a filter.

In the present invention, a plurality of disks are formed in the longitudinal direction in the flow direction of the gas, the gap between the disk and the disk is wider, and the gas is rotated together in the rotational direction of the disk between the disks by the pressure difference formed between the rotating disks. Induced

The dust discharger is installed on the rear side of the case of the rotating disk to improve the structure of the dust to naturally discharge the dust located on the side of the disk due to the specific gravity difference.

The dust bag 17 is connected to the lower part of the recovery port 8 for collecting the dust by a dust bag connection part 18, and the dust bag 17 is a paper-type filter commonly used in a vacuum cleaner. The remaining clean air is made of a bag-type filter which is discharged through the filter.
