In addition, the first dust collector 10 and the second dust collector 20 are located in parallel in the longitudinal direction.

Hereinafter, referring to FIG. 2, the operation of the combined cyclone dust collector according to the related art is as follows.

First, when the air suction unit (not shown) provided in the air discharge pipe 23 side of the second dust collector 20 is operated, air or contaminants flow into the inlet pipe 12 of the first dust collector 10, Among the pollutants, the large particles continue to move in the longitudinal direction in the same direction by the inertial force, and when moved along a certain length, the influence of gravity becomes greater than the inertial force, and is collected by the lower end of the inertial dust collecting body 11.

At the same time, the fine particles of air or non-dust collected contaminants are introduced into the second dust collector along the tangential direction of the cyclone body 21 constituting the second dust collector 20 through the contaminated air suction pipe 22. Is discharged to the outside through the air discharge pipe 23 and the fine particles are subjected to centrifugal force along the tangential direction. The microparticles subjected to the centrifugal force rotate while drawing a continuous circle and reach the pollutant outlet 24 to be collected by the dust collector of the first dust collector 10 through the pollutant outlet.

On the other hand, although not shown, the simple cyclone dust collector has only the structure of the second dust collector 20 of the above-described composite cyclone dust collector, and the polluted air outside by the polluted air suction pipe 22 is the cyclone body 21. Will be inhaled. The operation below performs the same operation as that of the second dust collector 20 of the combined cyclone dust collector.

That is, as illustrated in FIG. 3, the electrode unit 30 is provided on the contaminated air intake pipe 22 and charges particles of contaminants introduced into the cyclone body 21 and the cyclone. The collecting electrode unit 40 is included in a predetermined portion in the body to collect charged particles to the inner wall of the cyclone body.

Here, the charged electrode unit 30, as shown in Figure 3, is provided on the inside of the contaminated air intake pipe 22, the first electrode 31 to receive an external high voltage, and the inner wall of the contaminated air intake pipe A second electrode 32 is provided and grounded to the outside, and the contaminant particles are charged by an electric field formed between the first electrode 31 and the second electrode 32.

The potential difference between the third electrode 41 and the fourth electrode 42 may include the fourth electrode 41. Particles of charged contaminants are moved to the inner wall of the body of the cyclone.

Cyclone dust collector according to the present invention made as described above performs the following operation.

Contaminated air (air containing contaminants) flows into the cyclone body along the tangential direction of the cyclone body 21 through the contaminated air intake pipe 22, where air is discharged to the outside through the air discharge pipe 23 and contaminants Is subjected to centrifugal force along the tangential direction. The pollutants subjected to centrifugal force continue to circle and reach the pollutant outlet 24 to be collected by the pollutant outlet to the dust collector of the first dust collector 10.

Here, in the process of introducing the polluted air into the cyclone body 21 through the polluted air suction pipe 22, between the first electrode 31 to which a high voltage is applied and the second electrode 32 having a potential of "0". A strong electric field is formed. At this time, the particles of the contaminants are charged to a positive charge under the influence of a strong electric field. Thereafter, the positively charged contaminant particles are transferred to the cyclone body 21 and are positively charged by the potential difference formed between the third electrode 41 having a high potential and the fourth electrode 42 having a potential of "0". The charged contaminant particles move from the third electrode 41 with high potential to the fourth electrode 42 with low potential. That is, the contaminant particles are pushed out of the third electrode 41 provided at the periphery of the air discharge pipe 23 to move toward the fourth electrode 42 far from the air discharge pipe.

In addition, when different voltages are applied to each electrode, the contaminant particles may be negatively charged by the charged electrode unit 30, and the contaminant particles charged by the negative charge may be collected by the collecting electrode unit 40.

First, the collection electrode unit 40 according to the first embodiment of the present invention, as shown in Figure 3, may be located on the side of the air discharge pipe 23 of the cyclone body 21.

That is, while the contaminants are sucked into the cyclone body 21 through the contaminated air intake pipe 22, while turning from the contaminated air intake pipe 22 side to the air discharge pipe 23 side, while the centrifugal force applied to the contaminants becomes weaker, some The contaminants are piggybacked in the discharged air and exit to the air discharge pipe. At this time, the contaminants are moved to the inner wall of the cyclone body 21 by the collecting electrode unit 40 of the first embodiment of the present invention. Accordingly, the contaminants are piggybacked in the discharged air and do not escape to the air discharge pipe 23, but are effectively collected by the dust collector of the first dust collector 10. More specifically, as can be seen from the experimental data of Figure 6, when the dust collection performance of the prior art is 88%, the dust collection performance of the first embodiment of the present invention was 98%.

That is, while the contaminants are sucked into the cyclone body 21 through the contaminated air intake pipe 22, while turning from the contaminated air intake pipe 22 side to the air discharge pipe 23 side, while the centrifugal force applied to the contaminants becomes weaker, some The contaminants are piggybacked in the discharged air to exit the air discharge pipe. At this time, the contaminants are moved to the inner wall of the cyclone body 21 by the collecting electrode unit 50 of the second embodiment of the present invention. Accordingly, the contaminants are piggybacked in the discharged air and do not escape to the air discharge pipe 23, but are effectively collected by the dust collector of the first dust collector 10.

At the same time, as the contaminants which are not moved to the inner wall of the cyclone body 21 and are moved to the air discharge pipe 23 by gravity are filtered by the mesh type pipe, the contaminants are discharged to the air discharge pipe 23. Instead, the dust is effectively collected by the dust collector of the first dust collector 10. More specifically, as can be seen from the experimental data of Figure 6, when the dust collecting performance of the prior art is 88%, the dust collection performance of the second embodiment of the present invention was found to be 99%.

Third, the collection electrode unit 60 according to the third embodiment of the present invention, as shown in Figure 5, the cyclone body 21 of the contaminated air suction pipe 22 side is provided with the third electrode It can be made by having a 41 in a cylindrical shape.

That is, the contaminants are sucked into the cyclone body 21 through the contaminated air suction pipe 22, and the contaminants having a small particle size are relatively small in mass and are piggybacked into the air without being sufficiently subjected to centrifugal force, and are discharged to the air discharge pipe 23. At this time, the contaminant particles are agglomerated with each other by the collecting electrode unit 60 which is the third embodiment of the present invention. Therefore, the size of the contaminant particles is increased to improve the dust collection performance. More specifically, as can be seen from the experimental data of Figure 6, when the dust collection performance of the prior art is 88%, the dust collection performance of the third embodiment of the present invention was 98.5%.
