Description

  The present invention relates to a dust collector capable of removing airborne particulate matter in the field of air purification.

  Particulate suspended matter in the air, that is, dust, has been known as a cause of illnesses such as asthma and has been a target for removal in the past, but in recent studies, the particle size is 2.5 micrometers or less. There is a report that dust (so-called PM2.5) may induce diseases such as lung cancer, and further improvement of the collection technology is required. Among them, dust collectors that use electrostatic precipitating technology are excellent at collecting small particles with a particle size of micrometer or less, and have a low-pressure loss characteristic. There is a need for improved performance.

  Conventionally, as a dust collector of this type, a charging unit that charges dust by electric discharge is provided in the previous stage, and electrodes are stacked in the subsequent stage, and different voltages are applied alternately to form an electric field to collect charged dust. The thing which provided the dust collection part which collects is known. As an example in which this configuration is applied, Patent Document 1 is provided with a dust collection portion composed of an anode plate in which a metal foil is molded with an insulating resin, and a dust collection electrode plate provided in parallel with the anode plate. A dust collector is shown. Hereinafter, the dust collector will be described with reference to FIGS. 13 and 14. As shown in FIG. 13, the charging unit 101 includes a linear electrode 102 and a counter electrode plate 103, and a dust collection unit 104 is provided on the downstream side of the charging unit 101 in the ventilation direction. The dust collecting portion 104 has a structure in which an anode plate 105 and a dust collecting electrode plate 106 made of a conductive material such as metal are overlapped and wound in a roll shape. In addition, in order to allow air to pass through the dust collector 104, the dust collector electrode plate 106 is provided with conductive protrusions 107 in which arbitrary portions are bent zigzag, and the anode plate 105 and the dust collector electrode plate 106 are provided. Are superimposed at regular intervals. Further, as shown in FIG. 14, the anode plate 105 is formed by coating a metal foil 108 with a molding material 109 made of an insulating synthetic resin, and is short-circuited even if it contacts the dust collecting electrode plate 106 and the conductive projection 107. It has a structure that does not cause Further, the anode plate 105 is devised to provide a water repellent layer 110 on the surface by mixing a water repellent in the mold material 109 or applying or adhering a water repellent material to the mold material 109. In the charging unit 101, a voltage of +4 to +10 kV is applied to the linear electrode 102 by the high-voltage power source 111 to give a potential difference with the counter electrode plate 103 connected to the ground. In the dust collecting unit 104, A voltage of about +2 kV is applied to the anode plate 105 by the high-voltage power source 111, and a potential difference is given to the dust collection electrode plate 106 connected to the ground.

In the above configuration, a very strong electric field is created in the vicinity of the linear electrode 102 in the charging unit 101. Therefore, a substance having a charge in the air collides with air molecules, and electrons are separated from the air molecules, or the separated electrons adhere to other air molecules to become air ions. This is called air ionization. A discharge phenomenon in which air, which is an insulator between the earth electrodes, causes dielectric breakdown and ionization of the air with a certain large discharge current is called corona discharge. Air ions generated by corona discharge are collected. It adheres to dust contained in the air supplied to the dust device and charges the dust positively. The positively charged dust is introduced into the dust collecting portion 104 along the flow of the air flow, and is mainly applied to the dust collecting electrode plate 106 under the action of an electric field provided between the anode plate 105 and the dust collecting electrode plate 106. Clean air from which dust has adhered and has been removed is blown out from behind the dust collection unit 104. Further, since the water repellent layer 110 is provided on the surface of the mold material 109 of the anode plate 105, the surface does not get wet even when the humidity becomes high, and the charge on the surface of the mold material 109 disappears. The device which maintains dust collection performance by preventing is made.
Japanese Examined Patent Publication No. 6-45017

  In the dust collection part of the dust collector described in Patent Document 1, a space for allowing air to pass between the anode plate and the dust collection electrode plate is provided by providing a projection by bending on the dust collection plate. However, when the anode plate and the dust collecting electrode plate are bent, a portion where the distance between both electrode plates is large and a small portion can be formed, and the dust collecting performance is deteriorated at a portion where the distance between both electrode plates is large. There is a problem, and it is required to obtain a dust collecting action at every part of the dust collecting part.

  In addition, the folding height of the projection provided on the dust collection electrode plate is the stacking interval between the anode plate and the dust collection electrode plate, and the strength of the electric field in the space provided between both electrode plates depends on the folding height of this projection. However, if the distance between the two electrode plates is reduced by reducing the bending height of the protrusions in order to increase the electric field, the electric field in the space between the two electrode plates increases and the dust collection performance increases, but the space through which air passes is increased. There is a problem that it becomes smaller, that is, the pressure loss of the dust collecting part increases and it becomes difficult for air to pass through, and it is required to improve the dust collecting performance without increasing the pressure loss of the dust collecting part.

  In addition, since the projections of the dust collecting electrode plate come into contact with the mold material of the anode plate and become very close to each other, the capacitance increases at this contact portion, and a large amount of charge is accumulated in both electrode plates. There is a problem that a large noise is generated when the plate is short-circuited at a terminal portion or the like, and it is required not to increase the capacitance of the dust collecting portion.

  In addition, tobacco smoke floating in the air contains a large amount of conductive components such as solids such as carbon, liquid oils such as tar, and moisture. Further, the exhaust gas from automobiles and the like discharged into the air contains carbon particles having conductivity. The dust collecting apparatus described in Patent Document 1 completely prevents a short circuit between the anode plate and the dust collecting electrode plate by using an anode plate coated with a metal foil with a molding material made of an insulating synthetic resin in a dust collecting portion. However, a conductive film may be formed on the surface of the molding material by collecting dust containing a conductive component. When a conductive film is formed on the surface of the mold material, the charge on the surface of the mold material expressed by applying a voltage to the metal foil of the anode plate is released to the dust collecting electrode plate in contact with the mold material. And the electric field is not formed in the space provided between the anode plate and the dust collecting electrode plate, resulting in a problem that the dust collecting performance is deteriorated. And the conductive film which causes the disappearance of the electric charge developed on the surface of the mold material is not only the film formed by adhering so that the moisture gets wet. When the dust collection unit collects tobacco smoke or the like, a conductive film is formed by adhering not only moisture but also dust containing a conductive component to the surface of the insulator covering the electrode. And the movement of charge occurs due to the contact between the insulator covering the voltage application electrode and the earth dust collecting electrode, and as a result, the charge expressed on the surface of the insulator disappears and is not replenished to the surface of the insulator thereafter. The electric field is not formed in the space provided between the earth dust collection electrode and the voltage application electrode, and the dust collection performance is lowered. Therefore, there is a problem that dust collection performance deteriorates even if only water repellency is given to the surface of the insulator, and no matter what dust is collected, a conductive film is formed on the surface of the insulator covering the electrode There is a demand to prevent this.

  In addition, in the dust collecting part, there is a problem that strength cannot be obtained unless the contact part between the spacer and the electrode provided to hold the electrode at a constant interval and allow air to pass therethrough, and the spacer and the electrode It is required that the contact portions of the two are adhered.

  Some substances floating in the air enter the human body, such as fungi, mold, viruses, or allergens, and have adverse effects such as diseases. The substances that induce disease in the human body are collected by the dust collector. And inactivation is required.

  The present invention solves such a conventional problem, obtains uniform and high dust collection performance in all parts of the dust collection unit, and at the same time, does not increase pressure loss and capacitance when passing air, In addition, it can stably maintain high dust collection performance even when dust is collected and the dust collection section becomes dirty, and it has high strength and elasticity, and receives impact from the outside, or Dust collection unit that does not cause destruction or damage even when performing washing operations such as washing with water, or that enters the human body such as bacteria, mold, viruses, or allergens that float in the air and induces disease An object of the present invention is to provide a dust collecting device that can be collected and inactivated by using an air conditioner and an air conditioner equipped with the dust collecting device.

  According to the present invention, uniform and high dust collection performance can be obtained without increasing the pressure loss and capacitance of the dust collection unit, and the dust collection unit is in a dirty state by collecting dust. In addition, it is possible to obtain a stable and high dust collection performance semipermanently by preventing the charge on the electrode surface from disappearing.

It is possible to provide a dust collector and an air conditioner having an effect that a substance that induces a disease can be collected and inactivated by a dust collector.

  The dust collector of the present invention includes a fully insulated electrode in which the entire sheet-like conductor is covered with an insulator, and a non-conductive corrugated electrode in which an electrode terminal is provided in an arbitrary portion of the sheet-like non-conductor to form a corrugated shape Are alternately stacked to form a dust collecting portion, and different voltages are applied to the completely insulated electrode and the non-conductive corrugated electrode, respectively. Insulation between the two electrodes is ensured by using a completely insulated electrode covered with the. The non-conductive corrugated electrode means one having a surface resistivity of 10 8 Ω / □ or more, preferably 10 11 Ω / □ or more, and a volume resistivity of 10 10 Ω · cm or more, An electrode terminal for supplying electric charge to an arbitrary position on the surface is provided. The surface of the non-conductive corrugated electrode is non-conductive, but has an electrical property that allows a slight charge to pass therethrough and allows the charge supplied from the electrode terminal to be placed on the entire surface. The non-conductive corrugated electrode has a corrugated corrugated shape when viewed from the ventilation direction, and a uniform corrugated space is provided between the two electrodes by alternately laminating with a flat, completely insulated electrode. Yes. The corrugated shape here is not limited as long as it can create a space such as a wave shape, a triangular shape, or a square shape. Then, a charge corresponding to the voltage applied to the electrode terminal provided in an arbitrary part of the nonconductive corrugated electrode is uniformly applied to the surface of the nonconductive corrugated electrode through the electrode terminal, and a voltage different from that of the nonconductive corrugated electrode. It is a structure that makes it possible to provide a uniform electric field in each of the corrugated spaces surrounded by the fully insulated electrode and the non-conductive corrugated electrode to which is applied. The air containing dust charged by the charged part is uniform in shape, introduced into the space where the same electric field is provided, and receives the Coulomb force by the force of the electric field and adheres to the electrode surface. It is collected. The fully insulated electrode and the non-conductive corrugated electrode are stacked at the height of the corrugated non-conductive corrugated electrode, but the average value of the electrode spacing in the corrugated space provided between the two electrodes. Corresponds to a value smaller than the height of the corrugated peak, so that a stronger electric field can be obtained than when two electrodes are stacked in parallel with the height of the corrugated peak as the actual electrode interval. However, the size of the space through which the air passes is the same as that of the dust collecting part in which two electrodes are stacked in parallel with the corrugated crest height as the actual electrode interval, and the pressure loss when the air passes through does not increase. This has the effect of obtaining a dust collection part with improved dust collection performance without increasing pressure loss. In addition, the corrugated structure of the non-conductive corrugated electrode provides a space for dust-containing air to pass through the dust collecting part. The dust collecting part is formed by only two of the fully insulated electrode and the non-conductive corrugated electrode. Since it can be configured, a spacer or the like for providing a space is not required separately. In addition, since the surface of the non-conductive corrugated electrode is non-conductive, there is no effect of accumulating a large amount of charge at the contact portion at the apex of the corrugated mountain between the fully insulated electrode and the non-conductive corrugated electrode. The electrostatic capacity of the dust collecting portion does not increase.

  2. The dust collector according to claim 1, wherein the electrode terminal provided on the non-conductive corrugated electrode and the sheet-like conductor provided inside the fully-insulated electrode are connected to the fully-insulated electrode and the non-conductive electrode. It is characterized in that it does not overlap in projection when viewed from the direction in which the corrugated electrode is laminated. That is, when the dust collection part with the air intake surface in front is viewed from above, the electrode terminals provided on the non-conductive corrugated electrode and the sheet-like conductor provided inside the fully insulated electrode are projected. The electrode terminal provided on the non-conductive corrugated electrode and the sheet-like conductor provided inside the fully insulated electrode are very close to each other with the insulator of the completely insulated electrode interposed therebetween. Since the structure can be such that it does not become a distance, the electrode terminal provided on the non-conductive corrugated electrode and the inside of the fully-insulated electrode are also in the part where the peak of the non-conductive corrugated electrode and the fully insulated electrode are in contact with each other. The electric charge is not concentrated on the sheet-like conductor provided on the substrate. For this reason, it has the effect | action that the electrostatic capacitance of a dust collection part can be made small and the insulator of a fully insulated electrode can raise | generate a dielectric breakdown at the contact part of both electrodes, and can prevent an insulation failure.

  The dust collector according to claim 1 or 2, wherein the non-conductive corrugated electrode is provided with an electrode terminal at a side position of the non-conductive corrugated electrode in front and back with respect to the direction of air passing through the dust collecting portion. It is what.

A sheet-like conductor is provided. That is, as a structure of a completely insulated electrode, a sheet-like conductor is overlapped so that a center line is sandwiched between insulators having a larger width, or an end-face of the sheet-like conductor is covered with an insulator. By molding, it is possible to provide only an insulating portion without a sheet-like conductor at the side position which is front and rear with respect to the direction of air passing through the dust collecting portion. By doing so, the electrode terminal of the non-conductive corrugated electrode and the sheet-like conductor of the completely insulated electrode can be made continuous without being scattered, so that the capacitance and pressure loss during ventilation are small. It has the effect | action that a dust collector with high insulation and dust collection performance can be obtained easily.

  Further, in the dust collector according to any one of claims 1 to 3, the electrode terminal is provided at a single or a plurality of intermediate positions of the non-conductive corrugated electrode with respect to a direction in which air passes through the dust collecting portion. It is a feature. If the dimension of the non-conductive corrugated electrode in the ventilation direction, that is, the width is large, there is a possibility that charges will not spread to the surface away from the electrode terminal, and the electrode terminal is located at the center with respect to the width direction of the non-conductive corrugated electrode By providing, it is possible to spread the charge over the entire surface of the non-conductive corrugated electrode. Thus, it has the effect | action that dust collection performance can be made high stably.

Examples of the insulating resin include polyolefins such as polypropylene (hereinafter referred to as PP) and polyethylene (hereinafter referred to as PE), polyesters such as polyethylene terephthalate (hereinafter referred to as PET) and polybutylene terephthalate (hereinafter referred to as PBT), polystyrene (hereinafter referred to as PS), polycarbonate (hereinafter referred to as PC). ) And polyurethane. Insulating resin has a dielectric strength of 15 kV / mm or higher, and has very high insulating properties and good moldability and workability. Therefore, sheet-like conductors can be laminated and molded with insulating resin. It is possible to easily produce a completely insulated electrode having high insulation properties by coating with use. Moreover, since it is highly flexible, it is possible to obtain a dust collecting portion that is not damaged even when subjected to an impact. In addition, the dust collecting portion can be formed by forming a completely insulating electrode in a strip shape and winding it in superposition with a non-conductive corrugated electrode.

  The dust collector according to any one of claims 1 to 5, wherein the surface of the sheet-like non-conductor in the non-conductive corrugated electrode is semiconductive. Examples of the semiconductive material include nylon 6 or nylon 12, and hygroscopic resins such as copolymers using these nylons. Such a material absorbs a slight amount of moisture in the air and has a surface resistivity of 10 to 11-15 Ω / □ and a volume resistivity of 10 to 11-15 Ω · cm. The material having a resistance value within this range is non-conductive but has a semi-conducting property of passing a small amount of electric charge. Therefore, the charge supplied from the electrode terminal when used as a sheet-like non-conductor. Can be spread over the entire surface. Further, since it is highly flexible and has good thermoformability, it has an effect that it is easy to perform assembly processing such as corrugating and laminating and is not easily damaged. In addition, since the non-conductive corrugated electrode can play a role of ensuring the dust collection performance when the electric charge spreads on the surface, it is not necessary to supply the electric charge into the sheet-like non-conductive body. Therefore, a sheet insulator such as a resin such as PP, PE, PET, and PBT is used as a base material for obtaining strength, and a nylon 6 or nylon 12 semiconductive resin is provided on the surface, or a base material is used.

Examples thereof include a non-stretched nylon sheet or a semi-conductive film provided on a non-stretched PBT sheet. As a method for producing a resin sheet, there is a stretching method for enhancing strength by stretching the sheet after molding to make the arrangement direction of molecules uniform, but the stretched resin sheet is not good in heat workability after production. Have On the other hand, a so-called non-stretched resin sheet that is not stretched has a feature of good thermal workability after production, and thus has an effect that it is easy to perform a process of giving a corrugated shape.

  Further, in the dust collector according to any one of claims 1 to 10, a non-conductive corrugated electrode formed in a strip shape and a completely insulated electrode formed in a similar strip shape are overlapped and wound to form a roll shape.

Dust containing conductive components such as cigarette smoke adheres to the surface of the insulator of the fully insulated electrode or the entire dust collecting part, and a conductive film is formed. The charges developed on these surfaces move and disappear. As a result, the electric field in the space where dust passes is weakened. This weakening of the electric field causes a decrease in dust collection performance. In the present invention, since a silicone polymer film having insulating properties, water repellency, and micro gaps is provided on the surface of the insulator of the fully insulated electrode or the entire dust collecting portion, dust containing conductive components such as cigarette smoke is provided. Even if dust is collected, it can be prevented from continuously adhering to the surface of the dust collecting part, and as a result, the formation of a conductive film can be prevented. Even high dust collection performance can be maintained. In addition, since the silicone polymer has a great feature that it has high chemical stability, elasticity and adhesiveness, it strongly adheres to the entire surface of the dust collecting part, and forms a stable, strong and highly elastic film. Therefore, even if an external force such as scratching the surface of the dust collection part is applied, the silicone polymer film does not spill or peel off the surface of the dust collection part, and even if washing work such as washing is performed Since the silicone polymer film does not elute into the cleaning liquid, high dust collection performance can be obtained semi-permanently and stably. In addition, when a silicone polymer film is provided on the entire dust collection part, the contact surface between the fully insulated electrode and the non-conductive corrugated electrode is bonded with a silicone polymer having high adhesion and elasticity, so that the dust collection part The whole has great strength and elasticity. Therefore, even if it receives an impact from the outside, the dust collecting part has an effect that it can maintain an integrated state by adhesion without being destroyed.

By using, for example, titania or silica alumina fine particles fixed with silver components as an antibacterial agent, the silver component having antibacterial action can be uniformly dispersed in the antibacterial agent and uniformly in the dust collecting part. It has the effect that it can be attached. In addition, for example, by using an antidepressant mainly composed of thiabendazole, it is possible to suppress the growth of moss classified as a fungus. In addition, by using polyphenols with a phenolic hydroxyl group in the molecular structure, such as epicatechin gallate, as an antiviral agent, envelopes the envelope of the virus and spikes present on the surface of the envelope, thereby suppressing the infecting action on cells.

By applying a negative voltage to the discharge electrode and simultaneously connecting the counter electrode to the ground, an extremely strong electric field is generated near the sharp tip of the discharge electrode. As a result, the air near the tip of the discharge electrode is ionized to become ions, and negative ions, which are said to have a relaxation effect, are released so as to be repelled from the discharge electrode to which a negative voltage is applied. Then, the air is supplied to the room by the wind of the air blowing means. By supplying negative ions into the room in this way, a resident in the room is brought to a relaxation effect, and at the same time, the dust in the room is weakly charged, and the charged dust can be taken into the dust collecting portion and collected. In addition, by applying a positive voltage to one of the electrodes of the dust collection unit, the main body can be easily charged positively, and it is possible to obtain higher dust collection performance by bringing the negatively charged dust closer to the main body. It has the action.

  Moreover, the air conditioner of this invention is provided with the dust collecting apparatus in any one of Claims 1 thru | or 25 as described in Claim 26, It is characterized by the above-mentioned. By providing the dust collector according to any one of claims 1 to 25 in front of the heat exchanger of the air conditioner, the air conditioner can be stably provided with a high air cleaning function.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1)
The non-conductive corrugated electrodes 1 and the completely insulated electrodes 2 are alternately laminated, and the air suction surface of the dust collecting unit 3 in which different voltages are applied to the respective electrodes is shown in FIG. A cross-sectional view seen from the side is shown in FIG. Further, FIG. 3 shows a top view showing an example of a non-conductive corrugated electrode 1 using a single sheet-like non-conductor 4, and FIG. 4 shows a cross-sectional view from the side. The non-conductive corrugated electrode 1 has a structure in which the electrode terminals 5 are provided at both ends in the front-rear direction, that is, in the width direction of the sheet-like non-conductive body 4 in the air passing direction. And has a corrugated shape. The sheet-like non-conductor 4 uses a semiconductive resin such as nylon, and the electrode terminal 5 is formed by applying a metal foil such as aluminum or a conductive paint containing carbon or metal. FIG. 5 is a cross-sectional view of the non-conductive corrugated electrode 1 in which the sheet-like insulator A6 is used as a base material, the semiconductive layer 7 is provided thereon, and the electrode terminal 5 is provided on the semiconductive layer 7. Show. As the sheet-like insulator A6, an insulating resin such as PP or PBT is used, and the semiconductive layer 7 is provided thereon, and the electrode terminal 5 is provided thereon. As a method of forming the semiconductive layer 7, a thin sheet of resin having semiconductivity such as nylon is attached, or various metal ions such as sodium ions and various anions such as sulfate ions, and metal oxides such as zinc oxide. Specific examples include applying a paint containing a semiconductive component. FIG. 6 shows a top view of the fully insulated electrode 2 and FIG. 7 shows a sectional view seen from the side. The fully insulated electrode 2 has a structure in which both sides of the sheet-like conductor 8 are bonded so as to be sandwiched so as to be centered by a sheet-like insulator B9 having a wider width than that. Insulating structure. The sheet-like conductor 8 may be a metal foil such as aluminum, or a sheet-like base material coated with a conductive paint containing carbon or metal. As a material of the sheet-like insulator B9, an insulating resin such as PP, PE, PET, PBT, PS, and PC is mainly used. The non-conductive corrugated electrode 1 in the dust collecting portion 3 has a corrugated corrugated shape when viewed from the direction in which air passes, and the air passes by being alternately laminated with the completely insulated electrodes 2 having a flat shape. A space is provided. By applying different voltages to the non-conductive corrugated electrode 1 and the completely insulated electrode 2, a uniform electric field is provided in each space. Since the average distance between the electrodes is smaller than the height of the corrugated peak of the non-conductive corrugated electrode 1, the average value of the electric field strength provided in the space is, for example, a corrugated shape having the same peak height as that of the non-conductive corrugated electrode 1. It becomes stronger than the electric field of the dust collecting unit 3 in which two flat electrodes are stacked with the spacers interposed therebetween, and as a result, higher dust collecting performance can be obtained. On the other hand, the pressure loss during ventilation is inversely proportional to the size of the space through which air passes. In the dust collection part 3 in the present invention, a space formed by laminating the non-conductive corrugated electrode 1 and the fully insulated electrode 2 is one of the spaces through which air passes. Pressure loss is also the same as compared with one of the spaces formed in the dust collecting portion 3 in which two flat electrodes are stacked with a spacer having a corrugated shape with the same peak height as the corrugated corrugated electrode 1 As a result, it is possible to obtain the dust collection part 3 with improved dust collection performance while maintaining a low pressure loss. Further, as shown in FIG. 2, since the electrode terminal 5 and the sheet-like conductor 8 do not projectly overlap in the stacking direction of the non-conductive corrugated electrode 1 and the fully insulated electrode 2, the electrode terminal 5 And the sheet-like conductor 8 has a structure that does not approach the sheet-like insulator B9 of the completely insulated electrode 2 across the sheet-like insulator B9. Therefore, a large amount of charge is not accumulated by the electrode terminal 5 and the sheet-like conductor 8, and at the same time, the possibility that the sheet-like insulator causes dielectric breakdown is small. Further, FIG. 8 shows a front view of the dust collecting portion 3 in which the belt-like non-conductive corrugated electrode 1 and the belt-like fully insulated electrode 2 are overlapped and wound in a roll shape. Thus, the dust collection part 3 which has the same effect can be obtained also by setting it as a roll-shaped structure. As a merit of the dust collection part 3 having a roll-like structure, there can be mentioned that the non-conductive corrugated electrode 1, the fully insulated electrode 2 and the high-voltage power supply 111 are connected to one part for each electrode and can be minimized. In addition, when a silicone polymer film having insulating properties, water repellency, and micro gaps is provided on the entire surface of the dust collecting portion 3, the silicone polymer film contains dust containing conductive components. Since it adheres discontinuously by the micro gap, it is possible to prevent a conductive film formed by continuously adhering dust containing a conductive component on the entire surface of the dust collection unit 3. For this reason, the charges developed on the surfaces of the non-conductive corrugated electrode 1 and the completely insulated electrode 2 are not neutralized and disappear, and the electric field in the space provided on both electrodes does not weaken. High dust collection performance can be stably maintained for a long period of time even if the water is collected. In addition, since the silicone polymer has high chemical stability, adhesiveness, and elasticity, it firmly adheres to the surface of the dust collecting portion, and forms a film having elasticity and chemical stability. For this reason, since the silicone polymer film is not peeled off from the dust collecting portion by an external force or eluted by washing such as washing with water, the dust collecting portion 3 having a high dust collecting performance can be obtained semi-permanently. .

  Insulating resin is mainly used as the sheet-like insulator A6 and the sheet-like insulator B9. However, there is no difference in effect even if other materials such as inorganic materials are used as long as they have insulating properties. .

  In addition, as long as the completely insulated electrode 2 covers the entire sheet-like conductor 8 and is completely insulated, it is effective to use other methods such as molding the sheet-like conductor 8 with an insulator. Does not make a difference.

  Further, as a method of providing the sheet-like conductor 8 inside the completely insulated electrode 2, a conductive paint is applied to a narrower area on the sheet-like insulator B9, and the sheet-like conductor is coated on the surface to which the conductive paint is applied. Even with the method of bonding the insulator B9, the completely insulated electrode 2 having the same effect can be produced.

  Further, the non-conductive corrugated electrode 1 shown in FIG. 1 has a wave shape, but if a space through which air can pass can be provided between the non-conductive corrugated electrode 1 and the fully insulated electrode 2, There is no difference in effect even with other shapes such as a letter shape.

(Embodiment 2)
The same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. The experimental results of evaluating the dust collection efficiency of the dust collector having the dust collection unit 3 shown in the second embodiment are shown below. As shown in FIG. 9, when obtaining dust collection efficiency, an experimental apparatus installed in the order of the charging unit 101, the dust collection unit 3, and the blowing means 10 from the upstream side using a duct in a laboratory capable of controlling temperature and humidity. The air blowing means 10 was set so that the surface wind speed was 1.4 m / s, and the dust collection efficiency was obtained. Then, using a particle counter KC18 made by Lion, dust having a particle diameter of 0.1 μm or more contained in the air upstream of the charging unit 101 and downstream of the dust collecting unit 3 is measured, and the dust collection efficiency is calculated using the following formula: Was calculated.

η = (1−Cin / Cout) × 100
η: dust collection efficiency (%), Cin: dust concentration on the upstream side of the charged part (pieces / L), Cout: dust concentration on the downstream side of the dust collection part (pieces / L)
The charging unit 101 used in the experiment has three tungsten linear electrodes 102 having a diameter of 80 μm installed horizontally in an ABS box having a width of 100, a height of 50 mm, and a depth of 25 mm. A plate in which four counter electrode plates 103 were installed at an interval of 16 mm so as to be positioned at the center of the electrode 102 was used. A voltage of about 4 kV is applied to the linear electrode 102, the counter electrode plate 103 is connected to the ground, and when evaluating at a temperature and humidity of 20 ° C. and 40% RH, 5 μA, and when evaluating at 30 ° C. and 80% RH, 10 μA. Corona discharge was caused so as to obtain a discharge current, and the dust passing through the charging unit 101 was charged. The parts used to create the dust collection unit 3 are as follows. A sheet-like insulator B9 made of a strip-like PET film having a thickness of 50 μm and a width of 30 mm is adhered to both surfaces of a sheet-like conductor 8 made of a strip-like aluminum foil having a thickness of 15 μm and a width of 20 mm, and completely covered with an adhesive. This was prepared and used as a fully insulated electrode 2. Further, an electrode terminal 5 made of non-stretched nylon 80 mm thick and 30 mm wide sheet-like sheet-like non-conductive body 4, and 30 mm wide and 3 mm wide at both ends in a region of 50 mm thick and 3 mm wide band-like aluminum foil. A non-conductive corrugated electrode 1 having a peak height of 1.67 mm and a corrugated corrugated shape was used. The mountain height here means the distance in the height direction between the apex of the downward mountain and the apex of the upward mountain located next to it. The dust collecting part 3 used for evaluation as an example was obtained by superposing the strip-shaped non-conductive corrugated electrode 1 and the completely insulated electrode 2 thus created and winding them in a roll shape. It is soaked in a dissolved silicone polymer solution and dried, and has a structure in which a silicone polymer film is provided on the entire surface of the dust collecting portion. The structure of the dust collection part 3 used for evaluation as a comparative example is shown in FIG. 9, and the structure of the dust collection part used for evaluation as an example is shown in FIG. As shown in FIG. 9, the dust collecting part 3 used for evaluation as a comparative example is a strip-like fully-insulated electrode 2, a sheet-like insulator made of unstretched PBT having a thickness of 80 μm and a width of 30 mm, and a wave shape having a peak height of 1.67 mm The corrugated insulating corrugated sheet 11, the electrode 12 made of a sheet-like conductor, and the insulating corrugated sheet 11 are laminated in this order and wound in a roll shape on the entire surface, although not shown in the figure. A resin film is provided. In addition, all the dust collection parts 3 used for evaluation as a comparative example and an Example were created with the dimension shown in FIG. In the experiment, the electrode 12 made of a sheet-like conductor and the non-conductive corrugated electrode 1 are connected to the ground in each dust collecting section 3, and a voltage of 4 kV is applied to the fully insulated electrode 2 in each dust collecting section. As a result, a potential difference of 4 kV was applied between both electrodes in each dust collecting section 3.

  In the experiment, the dust collecting unit 3 is dirty when the humidity is low (20 ° C., 40% RH) and is not contaminated with tobacco smoke, and when the humidity is high (30 ° C., 80% RH) and the tobacco smoke is collected. We evaluated how the dust collection efficiency changes under the two conditions of time. Specifically, a new dust collecting unit 3 was incorporated in the experimental apparatus, and dust collection efficiency was measured in a laboratory controlled at 20 ° C. and 40% RH. After that, the dust collector equipped with the charging unit 101, the dust collecting unit 3 and the air blowing means 10 is assembled and operated while burning a total of 40 cigarettes in an acrylic box having a volume of 0.5 cubic meter to produce cigarette smoke. After collecting the dust, the dust collection part was brought into the laboratory where the temperature and humidity were controlled at 30 ° C. and 80% RH, and incorporated in the experimental apparatus to obtain the dust collection efficiency.

  Table 1 shows the specifications of the dust collector 3 that was evaluated, the dust collection efficiency, and other measurement results. The dust collection part 3 shown in the comparative example has a high dust collection efficiency of 99.5% under the conditions of 0 cigarette smoke and 20 ° C. and 40% RH, but the dust collection part shown in the examples. No. 3 has a dust collection efficiency of 99.9%, which is higher than the dust collection unit 3 shown in the comparative example. Next, after collecting 40 cigarette smoke, the dust collection efficiency was evaluated under the temperature and humidity conditions of 30 ° C. and 80% RH. As a result, the dust collection part 3 shown in the comparative example was 48.5%. On the other hand, the dust collection part 3 shown in the example was 76.9%, and it was found that the dust collection part 3 had higher dust collection performance than the dust collection part 3 shown in the comparative example under poor conditions. Although the dust collecting part 3 shown in the comparative example is provided with a fluororesin film on the entire surface, if a large amount of smoke from 40 cigarettes is collected, the fluororesin film can repel moisture. The dust containing the conductive component contained in the tobacco smoke adheres so as to cover the entire surface of the dust collecting portion 3. Therefore, a conductive film is formed on the surfaces of the completely insulated electrode 2 and the insulating corrugated sheet 11, and the dust collection efficiency is greatly reduced. That is, it was found that even if only water repellency is imparted to the surfaces of the completely insulated electrode 2 and the insulating corrugated sheet 11, dust collection performance deteriorates by collecting a large amount of tobacco smoke. On the other hand, the dust collecting unit 3 shown in the embodiment is provided with a silicone polymer film on the entire surface of the dust collecting unit 3 to suppress the formation of the conductive film, thereby preventing the non-conductive corrugated electrode 1 and the complete insulation. It was found that the charge developed on the surface of the mold electrode 2 is prevented from moving and disappearing, so that the reduction in dust collection efficiency can be reduced even if 40 cigarette smokes are collected. Here, as the air blowing means 10, there are blowers such as a cross flow fan and a sirocco fan.

  The capacitance measured between the two electrodes constituting the dust collection unit 3 is 0.33 nF in the dust collection unit 3 shown in the comparative example and 0.23 nF in the dust collection unit 3 shown in the example. Was almost equivalent. The dust collecting part 3 shown in the embodiment has a structure in which the non-conductive corrugated electrode 1 and the fully insulated electrode 2 are in direct contact with each other, but is equivalent to the dust collecting part 3 having a structure not in direct contact as shown in the comparative example. The surface of the portion other than the electrode terminal 5 of the non-conductive corrugated electrode 1 is non-conductive, and the electrode terminal 5 provided on the non-conductive corrugated electrode 1 and a sheet-like shape provided inside the fully insulated electrode 2 This is because the conductor 8 does not overlap in projection. That is, the portion of the non-conductive corrugated electrode 1 that is projected and overlaps with the sheet-like conductor 8 provided inside the fully-insulated electrode 2 is non-conductive and has a small amount of charge to be stored. Even when the electrode 1 and the fully insulated electrode 2 are in direct contact with each other, the capacitance is reduced. For this reason, when the capacitance is large, a large noise is generated when the non-conductive corrugated electrode 1 and the fully insulated electrode 2 are short-circuited at the terminal portion or the like. It has a structure that prevents the generation of large noises. In addition, when the sheet-like insulator B9 of the completely insulated electrode 2 causes dielectric breakdown, it becomes impossible to apply a voltage to the dust collecting part 3 and the function as the dust collecting part 3 cannot be performed. In the dust part 3, the electrode terminal 5 of the non-conductive corrugated electrode 1 and the sheet-like conductor 8 provided inside the fully-insulated electrode 2 do not projectally overlap with each other. The sheet terminal 8 provided inside the electrode terminal 5 of the non-conductive corrugated electrode 1 and the fully-insulated electrode 2 with the body B9 interposed therebetween is structured not to be very close to the sheet-shaped insulator B9. Therefore, the sheet-like insulator B9 of the fully insulated electrode 2 is prevented from causing dielectric breakdown as much as possible, and the function of the dust collecting part 3 can be maintained semipermanently.

Is desirable. Further, when a discharge is caused by the ionization means 16, a discharge current flows between the discharge electrode 14 and the counter electrode 15. However, the dust collection performance can be obtained only by weakly charging the dust in the air in the room. It is possible to set the discharge current to 1 μA / m3 or less per blown air volume by designing the dust part voltage, electrode spacing, and dimensions, and the amount of ozone generated by discharge and harming the human body is almost zero. Can be.

Can be collected. In addition, by applying a positive voltage to either the non-conductive corrugated electrode 1 or the fully insulated electrode 2 of the dust collecting unit 3, the dust collector main body can be easily charged positively, and the negatively charged dust It is possible to obtain a higher dust collection performance by bringing the main body close to the main body.

  Although the needle-like discharge electrode 14 is used, there is no difference in the effect even if it is other shapes such as a spine or a wire as long as the shape can cause discharge.

  Further, although the plate-like counter electrode 15 is used, the same effect can be obtained even in other shapes such as a rod shape or a nail shape as long as the discharge electrode can cause discharge.
