Abstract

The present invention provides a dust collecting electrode for an electric dust collector capable of suppressing deformation of a wavy shape to a flat shape when pulled in the longitudinal direction.
A linear flat portion having a predetermined width h is formed along a longitudinal direction at a central portion in the width direction of a strip-shaped conductive member made of aluminum, and the width of the flat portion is determined in the width direction of the conductive member. On both sides, wavy uneven portions 104 and 106 in which unevenness is repeated in the longitudinal direction are formed. Deformation in the longitudinal direction of the dust collecting electrode 100 as a dust collecting electrode for an electric dust collector is suppressed by the flat portion 102 not being extended even when pulled in the longitudinal direction, and as a result, the uneven portions 104 and 106 become flat. In addition, when the dust collecting electrodes 100 and 100 are stacked and wound, the fluctuation of the distance between the dust collecting electrodes 100 and 100 is suppressed, the contact area with air is increased, and the dust collecting ability is remarkably improved.

Description

  The present invention relates to a dust collecting electrode for an electric dust collector disposed in a dust collecting portion of an electric dust collector.

  Electric dust collectors are used as dust collectors for air purifiers, air conditioners, etc., and ionize pollutants that are fine particles in the air, such as dust and dust, by discharging, and these pollutants have strong dust collecting power. The air is adsorbed by a dust collecting electrode for an electric dust collector (hereinafter, also simply referred to as a dust collecting electrode) having an air purifier.

More specifically, pollutants in the air sucked into the electrostatic precipitator are charged with a (+) charge due to a high voltage, and the (+) charged pollutant is disposed in the dust collector. While being passed between the dust collection electrode as a cathode and the dust collection electrode as a cathode, the negative electrode receives a repulsive force from the anode and an attractive force from the cathode, thereby adsorbing to the dust collection electrode as the cathode. For this reason, contaminants are removed from the air.
Such a dust collection electrode is formed in a cross-sectional wave shape in order to increase the contact area with air and improve the dust collection capability (see Patent Document 1).

FIG. 5 is an exploded perspective view of a dust collecting portion of an electric dust collector including conventional dust collecting electrodes 16 and 18. FIG. 6 is a plan view showing a conventional dust collecting electrode 16, and FIG. 7 is also a side view in the width direction.
The dust collection electrodes 16 and 18 have substantially the same shape, and one is used as an anode and the other is used as a cathode. 6 and 7 illustrate the dust collecting electrode 16.

Each of the dust collecting electrodes 16 and 18 has a strip shape and is made of thin plate or film aluminum. As shown in FIGS. 6 and 7, the dust collection electrode 16 has a wave shape in which unevenness is repeated in the longitudinal direction. More specifically, the dust collection electrode 16 alternately protrudes toward the one surface side and the other surface side at regular intervals in the longitudinal direction. Bending protrusions 16a, 16a,... Are formed.
Such dust collecting electrodes 16 and 18 are stacked in a state in which the coated paper is in close contact with both surfaces of each dust collecting electrode 16 and 18 and further wound up in the longitudinal direction by a predetermined longitudinal length, It becomes a roll-shaped dust collector that occupies the required space.

  At this time, the dust collection electrode 16 wound up with the bent projections 16a, 16a,... Projecting on both surfaces of the dust collection electrode 16 and a plurality of folding projections projecting on both surfaces of the dust collection electrode 18 as spacers. And a dust collecting electrode 18. Further, a shaping operation is performed to relax and / or expand the dust collector so that the collected dust collecting electrode 16 and the collected dust electrode 18 are separated from each other by a substantially constant distance. In such a shaping operation, the bent protrusions 16a, 16a,... Of the dust collecting electrode 16 and the bent protrusions of the dust collecting electrode 18 serve as spacers, and therefore, between the dust collecting electrode 16 and the dust collecting electrode 18. It is easy to provide a substantially constant gap.

The dust collecting electrodes 16 and 18 as the dust collector formed as described above are arranged in the dust collecting portion of the electric dust collector.
For this purpose, the dust collector of the electric dust collector is provided with a box 8 having an air inflow hole formed on the bottom surface and an air outflow hole formed on the top surface. A lid 13 covering the opening of the part is provided, and a filter 12 using a metal net and dust collecting electrodes 16 and 18 as dust collectors are mounted inside the box 8.

The air sucked into the dust collector of the electric dust collector receives repulsive force from, for example, the dust collection electrode 16 as the anode while passing through the gap between the dust collection electrode 16 and the dust collection electrode 18 and collects as the cathode. It receives an attractive force from the dust electrode 18 and adsorbs to the dust collection electrode 18.
Japanese Utility Model Publication 2-311156

  However, since the conventional dust collecting electrode 16 has a simple wave shape in which unevenness is repeated in the longitudinal direction, when the dust collecting electrode 16 is pulled in the longitudinal direction by being wound in the longitudinal direction, the bent protrusion 16a. , 16a,... Are opened in the longitudinal direction of the dust collecting electrode 16, and the dust collecting electrode 16 may be deformed flat.

  When the flat dust collecting electrodes 16 and 18 are stacked, the dust collecting electrode 16 and the dust collecting electrode 18 are close to each other, and the gap between the dust collecting electrodes 16 and 18 is reduced. As a result, the density of the dust collector using the dust collection electrodes 16 and 18 is increased, and in order to form a dust collector of a required volume, the required amount of the length in the longitudinal direction of the dust collection electrodes 16 and 18 is required. Will increase.

Further, it is difficult to provide a gap having a certain separation distance between the flat dust collecting electrodes 16 and 18. Moreover, the separation distance between the flat dust collecting electrodes 16 and 18 is likely to change due to shaking, impact, or the like.
For this reason, the flow rate of air passing through the dust collector of the electric dust collector becomes non-uniform, and the flow rate of air may decrease. Moreover, the contact area between the flat dust collection electrodes 16 and 18 and the air is smaller than the contact area between the corrugated dust collection electrodes 16 and 18 and the air.
From the above, the dust collection capacity of the electric dust collector is reduced.

  This invention is made | formed in view of such a situation, The main objective is that the flat part is formed along the longitudinal direction of a strip | belt-shaped electroconductive member, and the uneven part is formed in the both sides of a flat part. Accordingly, it is an object of the present invention to provide a dust collecting electrode for an electric dust collector that can prevent the uneven portion from being flatly deformed when pulled in the longitudinal direction.

  Another object of the present invention is to provide a dust collecting electrode for an electrostatic precipitator that can improve the dust collecting ability of the electrostatic precipitator, because the uneven portions on both sides of the flat portion are symmetrical about the flat portion. It is in.

  Another object of the present invention is to provide a dust collecting electrode for an electrostatic precipitator that can improve the dust collecting ability of the electrostatic precipitator by arranging the uneven portions on both sides of the flat portion in a staggered arrangement.

  Still another object of the present invention is to provide a dust collecting electrode for an electric dust collector, which can easily form a required shape because the conductive member is made of aluminum.

  The dust collector electrode for an electrostatic precipitator according to the first device is a dust collector electrode for an electrostatic precipitator disposed in a dust collector of the electrostatic precipitator, using a strip-like conductive member, and a central portion in the width direction of the conductive member. In addition, a linear flat portion having a predetermined width is formed along the longitudinal direction, and wavy uneven portions in which the unevenness is repeated in the longitudinal direction are formed on both sides of the flat portion in the width direction. It is characterized by being.

  The dust collecting electrode for an electrostatic precipitator according to the second device is characterized in that the concavo-convex portion is formed in a substantially symmetrical shape with the flat portion as a symmetry axis.

  The dust collecting electrode for an electrostatic precipitator according to the third device is characterized in that the uneven portion on one side in the width direction of the flat portion and the uneven portion on the other side are arranged in a staggered manner.

  In the dust collecting electrode for an electrostatic precipitator according to the fourth device, the conductive member is made of aluminum.

In the case of the dust collecting electrode for the electrostatic precipitator of the first device, a linear flat portion having a predetermined width is formed along the longitudinal direction at the central portion in the width direction of the belt-like conductive member, On both sides in the member width direction, wavy uneven portions having unevenness in the longitudinal direction are formed.
The flat portion has a smaller deformation amount with respect to the tensile force in the longitudinal direction of the conductive member than the uneven portion. For this reason, when the conductive member is pulled in the longitudinal direction, the flat portion suppresses deformation of the entire conductive member in the longitudinal direction, and along with suppression of this deformation, deformation of the uneven portion in the longitudinal direction is also suppressed. .
As a result, it is possible to suppress the wave-shaped electrostatic precipitator dust collecting electrode from being deformed into a flat electrostatic precipitator dust collecting electrode.

A dust collector is formed by winding up such a plurality of wave-shaped dust collector electrodes for an electrostatic precipitator in a state of being stacked. At this time, a gap having a certain separation distance is easily provided between the stacked dust collector electrodes for the electrostatic precipitator, for example, using the convex portion of the concave and convex portions of each dust collector electrode for the electrostatic precipitator as a spacer.
For this reason, the density of the dust collector which uses the dust collection electrode for electric dust collectors of this invention becomes low. And the malfunction that the required amount of the longitudinal direction length of the dust collector electrode for electric dust collectors used in order to form the dust collector of a required volume increases excessively is suppressed.

Further, the separation distance between the corrugated dust collector electrodes is difficult to change due to, for example, shaking or impact because the convex portions of the concave and convex portions of each dust collector electrode serve as spacers.
As a result, the flow rate of the air passing through the dust collector of the electric dust collector becomes substantially uniform, and the problem that the flow rate of the air decreases is suppressed. In addition, the contact area of the corrugated electrostatic precipitator with the air is larger than the contact area of the flat electrostatic precipitator with the air.

  From the above, it is possible to improve the dust collection capability of the electric dust collector by using the minimum dust collecting electrode for the electric dust collector.

In the case of the dust collecting electrode for the electrostatic precipitator of the second device, the concave and convex portions are formed in a substantially symmetrical shape with the flat portion as the symmetry axis, so that the dust collecting electrode for the electrostatic precipitator is wound into a roll shape. The shape of the air flow passage formed inside the dust collector is simplified.
For this reason, air can smoothly flow in and out of the dust collector, and the dust collection capability of the electric dust collector can be further improved. Moreover, generation | occurrence | production of the noise by the inflow / outflow of air being inhibited can be suppressed.
Furthermore, the external appearance of the symmetrical dust collector electrode for an electric dust collector is improved.

  In the case of the dust collecting electrode for the electric dust collector of the third device, the uneven portions are staggered on one side and the other side of the conductive member width direction of the flat portion. That is, the concave and convex portions on one side in the width direction of the conductive member and the concave and convex portions on the other side in the width direction of the conductive member are alternately formed.

When a roll-shaped dust collector using such a dust collecting electrode for an electrostatic precipitator is shaken or impacted from the outside, the staggered arrangement of the dust collecting electrode for an electric precipitator effectively applies external force. Therefore, a gap having a certain separation distance is maintained between the stacked dust collecting electrodes for the electrostatic precipitator.
As a result, the flow rate of air passing through the dust collector of the electrostatic precipitator becomes substantially constant, and the problem that the flow rate of air decreases is suppressed, so that the dust collection capability of the electrostatic precipitator can be further improved. it can.

In addition, the concave and convex portions are arranged in a staggered manner on one side and the other side of the conductive member width direction of the flat portion, so that the dust collector electrode for the electrostatic precipitator is formed inside the dust collector that is wound up in a roll shape. The shape of the air flow passage is complicated.
For this reason, the amount of air flowing into and out of the dust collector in contact with the dust collecting electrode for the electric dust collector can be increased, and as a result, the dust collecting capability of the electric dust collecting device can be further improved.

  In the case of the dust collecting electrode for the electric dust collector according to the fourth device, the flat portion and the uneven portion are formed on the aluminum conductive member. Although the shape of such a dust collecting electrode for an electrostatic precipitator is complicated, a desired shape can be easily formed by, for example, molding using aluminum that is easy to process.

  Hereinafter, the present invention will be described in detail with reference to the drawings showing embodiments thereof.

Embodiment 1.
1 is a plan view showing a dust collecting electrode 100 as a dust collecting electrode for an electrostatic precipitator according to Embodiment 1 of the present invention. FIGS. 2 and 3 are side views in the width direction showing the dust collecting electrode 100 and FIG. It is a longitudinal direction side view.

Dust collecting electrode 100 is formed by molding a thin strip or film strip of an aluminum conductive member into a required shape, and has a thickness of about 0.1 mm in the present embodiment.
As shown in FIG. 1, the dust collecting electrode 100 is formed with a linear flat portion 102 having a predetermined width h along the longitudinal direction at the central portion in the width direction of the conductive member. A wavy uneven portion 104 in which unevenness is repeated in the longitudinal direction is formed on one side of the conductive member width direction, and an uneven portion 106 substantially similar to the uneven portion 104 is formed on the other side of the flat portion 102 in the conductive member width direction. It is formed.

  The uneven portions 104 and 106 in the dust collecting electrode 100 shown in FIGS. 1 to 3 are formed in a substantially symmetrical shape with the flat portion 102 as the axis of symmetry. That is, with respect to the longitudinal direction of the dust collection electrode 100, the convex portion (or concave portion) of the concave and convex portion 104 and the convex portion (or concave portion) of the concave and convex portion 106 are arranged at substantially the same position.

A dust collector is formed using two such dust collecting electrodes 100.
The dust collecting electrodes 100 and 100 are laminated in a state where a coated paper (not shown) is adhered to both surfaces of each dust collecting electrode 100, and further, the dust collecting electrodes 100 and 100 are wound in the longitudinal direction by a predetermined longitudinal direction length, thereby obtaining a required space. It becomes a roll-shaped dust collector.

Here, when each dust collecting electrode 100 wound up in the longitudinal direction is pulled in the longitudinal direction, the flat portion 102 is not formed with irregularities, and therefore the force that pulls the dust collecting electrode 100 in the longitudinal direction is flat. The flat portion 102 is hardly deformed in the longitudinal direction even when transmitted to. As a result, the length of each dust collection electrode 100 in the longitudinal direction is limited to the length of the flat portion 102 in the longitudinal direction, and the uneven portions 104 and 106 of each dust collection electrode 100 are extended in the longitudinal direction. It is suppressed. That is, the flat portion 102 functions as a means for suppressing the dust collection electrode 100 from being deformed in the longitudinal direction.
For this reason, each dust collecting electrode 100 becomes a roll-shaped dust collector while maintaining a wavy shape without being flattened even when pulled in the longitudinal direction.

Each of the wavy dust collecting electrodes 100, 100 has a gap between the collected dust collecting electrodes 100, 100 using, for example, the convex portions of the concave and convex portions 104, 106 protruding on both surfaces of the dust collecting electrodes 100, 100 as spacers. Is easily provided. Further, a shaping operation is performed to relax and / or expand the dust collector so that the collected dust collecting electrodes 100 and 100 are separated at a substantially constant distance.
The dust collecting electrodes 100 and 100 as dust collectors formed as described above are arranged in a dust collecting portion of a dust collecting electric dust collector (not shown) in the same manner as the conventional dust collecting electrodes 16 and 18 shown in FIG. Is done.

  The air sucked into the dust collector of the electric dust collector receives repulsive force from the dust collecting electrode 100 as an anode while passing through a gap having a substantially constant separation distance between the dust collecting electrodes 100 and 100, and serves as a cathode. The dust collecting electrode 100 receives an attractive force and adsorbs the dust collecting electrode 100.

  The concave and convex portions 104 and 106 of each dust collecting electrode 100 function as means for increasing the contact area between air and the dust collecting electrode 100 in order to efficiently collect dust in the air and contaminants such as dust. . For this reason, if the width h of the flat part 102 is too large, the concavo-convex parts 104 and 106 become small, and the dust collection capability of the electric dust collector decreases. On the other hand, if the width h of the flat portion 102 is too small, the function of the flat portion 102 as a means for suppressing the dust collecting electrode 100 from being deformed in the longitudinal direction is not sufficiently exhibited. From the above, as the width h of the flat portion 102, it is desirable to use an appropriate numerical value that achieves both the function of the flat portion 102 and the functions of the concavo-convex portions 104 and 106.

  In the dust collector using the dust collection electrodes 100 and 100 as described above, a gap having a certain separation distance is easily provided between the dust collection electrodes 100 and 100 stacked. As a result, the required amount of the length in the longitudinal direction of the dust collecting electrode 100 used for forming a dust collector having a required volume does not increase excessively.

Further, the separation distance between the wavy dust collecting electrodes 100 and 100 hardly changes due to shaking, impact, or the like.
For this reason, the flow rate of air passing through the dust collector of the electric dust collector becomes substantially uniform, and the flow rate of air does not decrease. In addition, the contact area between the wavy dust collection electrodes 100 and 100 and the air is larger than the contact area between the flat dust collection electrodes and the air.
From the above, the dust collection capability of the electric dust collector is improved by using the minimum dust collection electrode 100.

Embodiment 2. FIG.
FIG. 4 is a side view in the width direction showing a part of the state in which the dust collecting electrodes 100, 100 according to Embodiment 2 of the present invention are wound.
The dust collection electrode 100 of the present embodiment is substantially the same as the dust collection electrode 100 of the first embodiment. However, the uneven portion 104 on one side of the flat portion 102 in the width direction of the conductive member and the uneven portion 106 on the other side are staggered. That is, with respect to the longitudinal direction of the dust collection electrode 100, for example, the concave portion 104a included in the concave and convex portion 104 and the convex portion 106a included in the concave and convex portion 106 are arranged at substantially the same position.

  A dust collector is formed by winding in the shape of a roll in the state where the wave-like dust collecting electrodes 100, 100 as described above are laminated. At this time, by shaping the dust collector, a gap having a certain separation distance L is easily provided between the stacked dust collecting electrodes 100 and 100.

When such a dust collector is shaken from the outside, an impact or the like is applied, the concave and convex portions 104 and 106 arranged in a staggered manner in each dust collecting electrode 100 effectively disperse the external force. Is easily maintained.
For this reason, the flow rate of air passing through the dust collector of the electric dust collector becomes substantially uniform, and the flow rate of air does not decrease. As a result, the dust collection capability of the electric dust collector is further improved.
