Description

Multi-spindle type centrifugal blower {Multiple Disk Centrifugal Separation Fan}

    The present invention relates to a multi-rotating plate-type centrifugal blower, which will be described in detail, when a plurality of disks are formed at regular intervals in a snail-shaped case and installed in a longitudinal direction in a gas flow to rotate the disks. In the direction of disk rotation, the gas introduced through the inlet flows through the disk together, and the dust contained in the gas is collected toward the case by the specific gravity of the dust while flowing through the disk, which is rotated with the gas. As it rotates as it is discharged through the dust outlet formed in the lower side of the case back, the gas without dust in the center of the disc is discharged through the outlet formed in the lower portion of the inlet, the disk is rotated to reach the inlet to the gas containing dust Flow into the case and repeat the same operation Relates to a multi-rotating plate-type centrifugal blower.

Gravity, inertial force, centrifugal force, washing, filtration, electrostatic precipitation are methods for separating solid particles from gas streams. Recently, the charges and the ionizer through electrostatic separation alternately wash the dust collector. A method using an electrode acting in the passage between the disk-shaped pens formed by the above has been developed.

Korean Patent Application Publication No. 0156540 is provided by continuous electrostatic separation of impurity particles ionized in a separation means comprising a dust collecting surface disposed along passages through which the charge augmentation and gas flows pass through the ionization means. Is formed between the fixed voltage-transmitting plate and the rotatable ground disk, and the plate and the disk have the same space as each other, and the gas purifying device is described in which the fixed washing means removes the deposited impurity particles on the disk.

Korean Patent Laid-Open Publication No. 1999-37636 discloses a disk-shaped impeller formed with a plurality of pumping grooves recessed in a radial direction along a ship surface to prevent body parts from being worn during rotation.

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 entering 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 rotary plate-type centrifugal blower.

   In order to achieve the above object, the present invention forms a plurality of disks at regular intervals in the vertically installed snail-shaped case installed in the longitudinal direction of the gas flow to rotate the disks, the direction in which the disk rotates Accordingly, the gas introduced through the inlet flows together between the disks, and the dust contained in the gas is collected toward the disk rim by the specific gravity of the dust while flowing through the 1 ~ 30mm, the space between the disks which are rotated up and down with the gas. While being rotated together with the gas, it is discharged through the dust outlet formed at one side of the lower rear of the case, and gas without dust at the center of the disc is discharged through the outlet formed at the lower part of the inlet, and the disc is rotated to reach the inlet to contain dust. Injected gas into the case and repeat the same operation It relates to a multi-rotating plate-type centrifugal blower.

In general, when rotating a plurality of disks, the gas flows along with the rotating disk and the rotating disk by the friction force. 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.

The dust-containing gas moves through the intake pipe 2 into the space 5 between the plurality of disks of the rotor and rotates. Particles are transferred to the transverse wall 9 of the body case 1 by the influence of centrifugal force. 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. ), And the purified gas is discharged through the exhaust pipe (3). It removes the dust contained in the gas in the apparatus continuously transported to the 1 ~ 30mm space in the original disk and rotated continuously in this way, and centrifuged the dust of the impregnated gas in the multi-turn plate centrifugal blower without a separate dust collector. It is the principle of elimination.

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 fine particles in the air. According to the present invention, several outlets 7 are provided on the lateral wall 9 for discharging air containing particles and a high concentration of dust, and the concentrated high concentration impregnated air passes through the recovery port 8 and the dust bag 17. Through this, complete separation of air and dust occurs. At this time, the clean air from which the dust is separated is discharged through the exhaust pipe (3).

In the present invention, a plurality of disks are formed in the longitudinal direction in the flow direction of the gas, and the gap between the disk and the disk is made wider, and the friction forces formed between the rotating disks induce the gas to rotate together in the rotational direction of the disk between the disks. And

By installing a centrifuged dust outlet on the rear side of the case of the rotating disk is a multi-rotating plate-type centrifugal blower with an improved structure to naturally discharge the dust separated toward the rim of the disk by centrifugal force.

The dust bag 17 is connected to the lower part of the recovery port 8 for collecting dust by a dust bag connection part 18, and the dust bag 17 is a type of a filter that is usually used in a filter bag. The dust remains inside and some of the air that comes in with the high concentration of dust is filtered through a filter and then discharged to clean air. If gaseous contaminants remain in the air filtered through the filter, the dust bag storage 19 may be sealed and the duct may be connected to the exhaust pipe 3 to be discharged through the chimney.
