Description

Dust removal device {DUST REMOVAL APPARATUS}

The present invention relates to a dust removal device.

In particular, the present invention relates to a dust removal device capable of reducing ozone generation below an indoor permissible standard while based on generation of ion wind induced by high voltage.

Dust refers to small-sized particles emitted into the atmosphere by wind, volcanic eruptions, natural activities, and the like. As the industry develops, dust also increases, and accordingly, dust has a bad effect on human lungs, bronchial tubes, etc., causing respiratory diseases. Recently, it is known that dust has an adverse effect on the brain, heart, organs, sensory organs, etc. in addition to the human bronchus, and great attention is being paid to dust removal.

Various methods are used for dust removal, such as a filter method that passes a filter and a cyclone method that removes dust by rotating air.

The discharge-type dust removal method applies a high voltage to give polarity to dust and collects ionized dust. However, this method of removing dust has the disadvantage of not being able to remove dust in the air satisfactorily and contaminating the air by forming ozone. In addition, when a high-voltage voltage is applied, problems such as damage to wire-type electrodes mainly used in dust collectors have also occurred.

Accordingly, the voice of demand for a dust removal device that solves these problems is increasing.

In addition, in describing the present invention, if it is determined that a detailed description of a related known configuration or function may obscure the gist of the present invention, the detailed description will be omitted.

In addition, the size or shape of the components shown in the drawings may be exaggerated for clarity and convenience of description. In addition, terms specifically defined in consideration of the configuration and operation of the present invention are only for describing the embodiments of the present invention, and do not limit the scope of the present invention.

1 is an exploded perspective view of a dust removal device of the present invention according to an embodiment.

The dust removal device of the present invention according to an embodiment includes a fixed frame 300, a high voltage plate pole 100, and a high voltage wire pole 200.

The fixing frame 300 is composed of two, and each inlet groove 130 may be formed. The fixing frame 300 is composed of two and may be disposed on the upper side 310 and the lower side 320, respectively. An inlet groove 130 may be formed in each fixing frame 300 .

The inlet groove 130 may be formed to have a specific length so that the length of the gap between the high voltage wire pole 200 and the high voltage plate pole 100 can be changed as needed. The reason why the inlet groove 130 is formed to have a specific length is that the efficiency of dust in the air and the amount of ozone generated differ depending on the distance between the high voltage wire pole 200 and the high voltage plate pole 100, so it is necessary to change this distance as necessary. because there is This will be explained in detail later.

Meanwhile, the lower part 320 of the fixing frame may serve as a ground. Thus, the charged dust can be located and stored on the lower side.

The high voltage plate electrode 100 may serve as a ground. The high voltage plate electrode 100 is composed of a plurality of pieces. Preferably, the high voltage plate electrode 100 may be composed of six. Each of the high voltage plate electrodes 100 may be connected so that one side and the other side come into contact with each other. That is, one side of one high voltage plate electrode 100 is disposed while abutting the other side of another high voltage plate electrode 100 . The high voltage plate electrode 100 may be arranged in a specific shape by being arranged in this way. For example, six high-voltage plate-shaped electrodes 100 may be disposed so as to abut each other so that a cross section has a shape of a hexahedron.

The high voltage plate electrode 100 may include a main part 110 and a wing part 120 . The main part 110 may be formed in the shape of a flat plate. The wing portion 120 may also be formed in the shape of a flat plate, but may be formed in a form extending from both ends of the main portion 110 at an angle set with the main portion 110 . Here, the angle between the main part 110 and the wing part 120 may be greater than 100 degrees and less than 150 degrees. Preferably, the angle between the main part 110 and the wing part 120 may be 120 degrees. The angle between the main part 110 and the wing part 120 will be described later in detail.

The high voltage wire pole 200 may be spaced apart from the high voltage plate pole 100 by a set distance. The number of high voltage wire poles 200 may correspond to the number of high voltage plate poles 100 . More precisely, the number of high voltage wire poles 200 corresponding to the number of main parts 110 may be configured. Fixed bodies may be disposed on both sides of the high voltage wire pole 200 . The fixing body can be inserted into the inlet groove 130 to fix the high voltage wire pole 200 to the fixing frame 300 .

The high voltage wire electrode 200 may be formed of a carbon fiber electrode. Therefore, the high voltage wire pole 200 can allow a high current to flow when a specific voltage is applied, and may not be damaged even when a high current is applied at the same time.

The high voltage wire pole 200 is formed in the form of a conductor bar through which a current can flow and a conduction frame in which an inlet hole is formed at set intervals surrounding the conductor bar, and a carbon fiber electrode is inserted into the inlet hole. Here, the position of the carbon fiber electrode is preferably disposed in the opposite direction (radial direction) instead of facing the main part 110.

As described above, the present invention includes the fixed frame 300, the high voltage plate electrode 100, and the high voltage wire pole 200, so that dust in the air can be removed and at the same time, ozone generation can be significantly reduced. Hereinafter, the reason why each component of the present invention is formed as above will be described in detail.

2 illustrates a direction in which ion wind moves in a dust removal device according to an embodiment of the present invention.

As a result of analyzing the ion wind formed by the discharge of the dust removal device according to the present invention, it was confirmed that the ion wind moved in a symmetrical shape with respect to the center of the main part 110. It was confirmed that the ion wind moved from the center of the main part 110 in a direction closer to the main part 110, then moved roundly in the direction of the wing part 120, and then moved in a direction further away from the main part 110. In the present invention, since such ion wind is formed in the main part 110 and the wing part 120 arranged in a hexahedral shape, dust in the air can be effectively removed. In addition, the ion wind was formed better as a higher current was applied to the high voltage wire pole 200.

Figure 3 shows an experiment for setting the angle of the present invention wing portion according to one embodiment in order.

In order to form the shape of the high voltage plate electrode 100 of the present invention, the angle of the main part 110 and the wing part 120 was changed in various ways and the strength of the current was checked.

For example, as shown in FIG. 3, the angle between the main part 110 and the wing part 120 was set to 135 degrees and also set to 120 degrees. In addition, the high-voltage plate-shaped electrode 100 is arranged to have a square cross section, or to have a pentagonal cross section, or to have a hexagonal cross section. Also, the distance between the high voltage wire pole 200 and the high voltage plate pole 100 was changed.

As a result, when the angle between the main part 110 and the wing part 120 is formed between 100 and 150 degrees, a high current flows between the high voltage plate pole 100 and the high voltage wire pole 200 compared to the application of the same voltage Confirmed. Specifically, it was confirmed that the highest current flows when the angle between the main part 110 and the wing part 120 is 120 degrees.

In addition, when the cross section of the high voltage plate electrode 100 is arranged to form a hexagon, it was confirmed that a high current flows between the high voltage plate electrode 100 and the high voltage wire electrode 200 with respect to the same applied voltage. In addition, it was confirmed that the closer the distance between the high voltage wire electrode 200 and the high voltage plate electrode 100 is, the higher the current compared to the applied voltage flows.

(However, the relationship between the distance between the high voltage wire pole 200 and the high voltage plate pole 100 versus the size of the flowing current can obtain slightly different results from the experimental results when the high voltage plate pole 100 is arranged in a pentagonal shape or more. The reason for this will be explained in detail later.)

In conclusion, as shown in FIG. 3, the angle between the main part 110 and the wing part 120 is 120 degrees, arranged in a hexagonal shape, and the angle between the relatively high voltage wire pole 200 and the high voltage plate pole 100 is In the case of proximity, a high current flows between the high voltage plate pole 100 and the high voltage wire pole 200 with respect to the same applied voltage, so that the CADR (Clean Air Delivery Rate) value can be large.

4 shows an experimental process for selecting a material for the high voltage wire pole 200 of the dust removal device according to an embodiment of the present invention.

As described in FIG. 3 , when a high current flows between the high voltage plate electrode 100 and the high voltage wire electrode 200 when the same voltage is applied, it was confirmed that dust removal (CADR value) in the air increases. Here, the flow of high current when the same voltage is applied may also affect the material of the wire.

As a typical type of wire, as shown in FIG. 4, a common wire (shown as STATIC WIRE in FIG. 4), a copper and zinc alloy wire used for guitar strings (Guitar in FIG. 4), carbon fiber electrode replaced There is a high voltage wire pole 200 (Metal fiber is indicated above in FIG. 4, SUS fiber is indicated below and above in FIG. 4, and the shape of the high voltage wire pole 200 is the same as in FIG. 1).

In order to form the high voltage wire electrode 200, various wires were spaced apart at the same distance as the high voltage plate electrode 100 selected in FIG. 3 and voltage was applied.

As a result of the experiment, when the carbon fiber electrode is disposed in the opposite direction (indicated under the SUS fiber in the bottom of FIG. ) It was confirmed that the highest current compared to the application of the same voltage was formed between the high voltage plate electrode 100 and the high voltage wire electrode 200. In addition, since the high voltage wire electrode 200 is formed of a carbon fiber electrode, it has the advantage of not being damaged even when a high current is applied.

However, even if a high current is generated, there is a problem that ozone is generated due to it, so a high voltage should not be recklessly applied.

5 is an experimental example confirming the ozone generation amount of the dust removal device of the present invention according to an embodiment.

The amount of ion generation was measured using the high voltage plate electrode 100 selected through the experiment shown in FIG. 3 and the high voltage wire pole 200 selected through the experiment shown in FIG. 4 . Here, the distances between the high voltage wire pole 200 and the high voltage plate pole 100 were set to 60 mm, 80 mm, 140 mm, and 186 mm. In addition, the high voltage wire pole 200 and the ionmeter for measuring ions were placed 100mm apart.

As a result of the experiment, it was confirmed that the amount of ozone generated increased as the applied voltage was large and the current flowed. there was.

Based on these results, a dust removal device that can best remove dust in the air can be formed. This can be seen by checking the ‘CADR/ozone production’. That is, if ozone generation cannot be prevented, but the dust removal amount in the air is high in proportion to it, this would be the most desirable dust removal device.

As a result of the experiment, as can be seen in FIG. 5, it was confirmed that the distance between the high voltage plate electrode 100 and the high voltage wire pole 200 was 184 mm, and the value of CADR/ozone production was the highest when 17 kV was applied.

6 is an experimental example confirming the cause of not increasing the value of CADR versus applied voltage in the dust removal device of the present invention according to an embodiment.

As confirmed earlier in the description of the present invention through FIG. 3, when the high voltage plate electrode 100 is arranged in a hexahedral shape, even if the applied voltage is recklessly increased, the CADR (Clean Air Delivery Rate) value does not increase in proportion to it. could confirm that

It was confirmed that the reason is that when a voltage is applied to the high voltage wire pole 200 and current is generated, interference occurs in adjacent parts as shown in FIG. 6 . In other words, it was confirmed that the current in one part affects the other part, so that the CADR (Clean Air Delivery Rate) value is reduced. In this case, it has been confirmed that this can be solved by increasing the length of the high voltage plate pole 100 and the high voltage wire pole 200 to increase the length of the fixed frame 300 disposed on the lower side.

Overall, the dust removal device of the present invention formed through FIGS. 2 to 6 is as follows.

The high voltage plate electrode 100 is composed of a main part 110 and a wing part 120, and the angle thereof is between 100 degrees and 150 degrees, but 120 degrees is preferable. The high voltage plate-shaped electrode 100 is preferably arranged to have a hexagonal cross section.

And the high voltage wire electrode 200 is replaced with a carbon fiber electrode. The high voltage wire pole 200 and the high voltage plate pole 100 are disposed at a set interval. Here, the set distance between the high voltage wire pole 200 and the high voltage plate pole 100 is preferably within a range of 50 mm to 200 mm.

Meanwhile, the control unit 500 includes the distance between the high voltage wire pole 200 and the high voltage plate electrode 100 based on the vertical length of the high voltage wire pole 200 or the carbon fiber electrode, and power applied to the high voltage wire pole 200. The intensity of (voltage) is preset.

Therefore, in the present invention, the size of the power to be applied based on the vertical length of the high voltage plate electrode 100 or the high voltage wire pole 200, the separation distance between the high voltage plate pole 100 and the high voltage wire pole 200 are regulated It is arranged to minimize the amount of ozone generated while removing dust in the air, and the high voltage wire pole 200 is not damaged even when a high current flows.

The control unit 500 may receive the sensor values transmitted by the sensor unit 400 to check the operation of each component and problem situations. As an example, when a set voltage is applied, the current between the high voltage wire pole 200 and the high voltage plate pole 100 should flow a current of a predetermined size as described above, but otherwise the result may be sensed.
