Description

Ion wind air purifier {IONIC WIND TYPE AIR CLEANER}

The present invention relates to an ion air purifier, and more particularly, it is easy to maintain and maintain through simple removal/installation of a configuration in which particles are collected while collecting charged particles by corona discharge, and ozone when used in a closed space It relates to an ion wind air purifier that can reduce the concentration of

Fine dust is an immediate problem that threatens public health. The public's awareness of fine dust is getting worse as time goes by, and the government is putting all its efforts into reducing fine dust at the pan-government level.

On the other hand, about 7% of the fine dust in the air in Seoul is emitted from grilled restaurants such as meat or fish, and the concentration of ultrafine dust soars to 13 times the 'very bad' standard (1013㎍/㎥). It is threatening the health of customers and customers, but at present, measures at the government level are far from being taken.

An electric precipitator that removes fine dust contained in the air flow of about 1 m/s generated by a blower using corona discharge can be an effective countermeasure to civil complaints surrounding fine dust emitted by grilled restaurants and odor pollution. .

However, the configuration in which the fine dust is collected is a consumable due to the fine dust collected on the surface, and therefore needs to be periodically cleaned or replaced. However, in the case of most ion air purifiers, it is difficult to replace such a configuration, and the solution is solved by additionally introducing a wet cleaning configuration. However, this increases the cost and is pointed out as a problem that it is difficult to use at home.

In addition, there is a decisive problem of generating ozone harmful to the human body when corona discharge is used. Although the collection efficiency increases as the applied current increases, the ozone concentration also increases, making it difficult to use indoors.

Therefore, there is a need for the development of an ion air purifier that is convenient to replace the configuration in which fine dust is collected and does not increase the ozone concentration when used indoors.

The ion wind air purifier 1000 according to an embodiment of the present invention includes an emitter 100 , a collector module 200 (see FIG. 6 ), a non-collecting unit 300 , and a case 400 .

In the ion air purifier 1000, the emitter 100, the collector module 200, and the non-collecting unit 300 can be arranged in various ways, but in this embodiment, the emitter 100 is the collector module 200 and the non-collecting unit. (300) It will be described as being arranged below.

In this embodiment, the emitter 100 may be formed of a thin wire. Alternatively, in another embodiment, by processing a thin metal plate, it may be provided in a sawtooth shape. A high voltage is applied between the emitter 100 and the collector 210. Based on the collector 210, when the voltage of the emitter 100 is high, positive discharge (+ discharge), and when the voltage of the emitter 100 is low, it is negative. Discharge (-discharge). At this time, the application of the high voltage may be supplied through a high voltage power supply (not shown).

Meanwhile, in the present embodiment, the emitter 100 uses a tungsten wire having a diameter of 0.05 mm, but is not limited thereto.

The collector module 200 is disposed above the emitter 100 , and a plurality of collectors 210 are disposed to be spaced apart from each other. The plurality of collectors 210 are connected to each other through a connecting member. This will be described later.

3 is an explanatory diagram of particle collection of an ion wind air purifier according to an embodiment of the present invention.

When a high voltage is supplied to the emitter 100 , an electric field of high intensity is formed near the surface of the emitter 100 , and when the intensity of the electric field exceeds a specific value, positive and negative ions coexist around the emitter 100 . A plasma region is formed. In this region, electrons are accelerated at a high speed and collide with air molecules, causing an ionization phenomenon that separates air molecules into positive ions and electrons. This process is also called an electron avalanche because it generates a large amount of electrons and positive ions in an instant.

Corona discharge occurs. The movement of these cations is the Coulomb force of ions in the space between the emitter 100 and the collector 210 .

: charge density,

: the strength of the electric field), and the action of this force balances the force with the reaction that occurs when ions collide with neutral molecules. The overall movement of neutral air molecules moving in the direction in which the ions move due to collision with ions is the ion wind.

As the emitter 100 is disposed below the collector 210 , the ion wind forms an upward airflow. In addition, the positive ions moving from the emitter 100 to the collector 210 collide with and attach to particles in the atmosphere, thereby charging the particles with a positive (+) charge. When the air moves toward the collector 210, which is the outlet side, due to the collision of ions and neutral molecules, a negative pressure is formed in this space, so that external air is introduced again from the emitter 100 side, which is the inlet side, and a constant flow rate is generated.

The non-collecting unit 300 is configured so that the charged particles are collected by the collector 210 . A plurality of non-collecting units 300 are provided and are alternately (alternatively) disposed with the collectors 210 . That is, a high voltage is applied to the non-collecting unit 300 so that the positively charged particles are collected by the collector 210 .

That is, in the present embodiment, the collector 210 is configured to charge particles through corona discharge and generate an ion wind in relation to the emitter 100 , and in relation to the non-collecting unit 300 , the charged particles are collected. do In other words, in the present embodiment, the collector 210 and the collecting electrode have an integrated structure.

In the present embodiment, the length of the collector 210 is longer than the length of the non-collecting part 300 . The region corresponding to the emitter 100 of the collector 210 functions as a collector, and the region corresponding to the non-collecting part 300 functions as a collecting electrode. At this time, the end of the collector 210 protrudes toward the emitter 100 compared to the end of the non-collecting part 300 . Here, protruding means that the end of the collector 210 is closer to the emitter 100 than the end of the non-collecting part 300 (see FIG. 3). The end of the collector 210 is the end of the non-collecting part 300. By protruding toward the emitter 100 compared to the end, the electric field around the emitter becomes stronger.

4 is a front view of the case of the ion wind air purifier according to an embodiment of the present invention, and FIG. 5 is an enlarged view of the main part of the case of the ion wind air purifier according to an embodiment of the present invention.

The case 400 includes a pair of sidewalls 500 spaced apart from each other and a fixing part 600 . The fixing unit 600 has a configuration in which the emitter 100 , the collector module 200 , and the non-collecting unit 300 are mounted. The fixing part 600 includes an emitter fixing part 610 , a collector fixing part 620 and a non-collecting part fixing part 630 .

The emitter fixing part 610 is mounted on the side wall 500 . In this embodiment, both ends of the emitter fixing unit 610 are mounted on the inner surfaces of the pair of sidewalls 500, respectively, but there may be various coupling examples, and any one coupling method is not limited thereto.

Meanwhile, in the present embodiment, since the emitter 100 is disposed below the collector 210 , the emitter fixing unit 610 is mounted under the sidewall 500 .

The emitter fixing part 610 may be mounted through the emitter 100 , or a mounting groove 611 may be formed to place the emitter 100 .

The collector fixing part 620 is disposed above the emitter fixing part 610 . A plurality of groove portions 621 are formed to be spaced apart from each other in the collector fixing portion 620 , and a lower end of each collector 210 is inserted into each groove portion 621 .

In this embodiment, a separation space 612 is formed between the emitter fixing part 610 and the collector fixing part 620 . The separation space 612 is formed between the mounting groove in which the emitter 100 is mounted and the groove 621 . The separation space 612 is formed to prevent insulation breakdown. In the absence of the separation space 612 , insulation breakdown may occur even at a very low voltage (2 to 3 kV). That is, creepage discharge may occur from the emitter 100 to the collector 210 at a low voltage, and if the surface is contaminated, the breakdown voltage is further lowered. Therefore, creepage discharge is prevented by forming the separation space 612 .

In addition, the emitter fixing part 610 and the collector fixing part 620 may be integrally formed. That is, the emitter fixing part 610 and the collector fixing part 620 may be integrally connected to each other, but a space 612 may be formed. In this embodiment, both ends of the emitter fixing part 610 and the collector fixing part 620 may be provided integrally with each other, and a space 612 may be formed therebetween. Since the emitter fixing part 610 and the collector fixing part 620 are integrally formed, the distance between the emitter 100 and the collector 210 is constantly maintained. If this distance is referred to as the electrode spacing, the current changes approximately in inverse proportion to the cube of the electrode spacing when the applied voltage is constant. Therefore, even a small change in the electrode spacing causes a fatal problem in that the current changes a lot. However, in this embodiment, since the emitter fixing part 610 and the collector fixing part 620 are integrally formed, the distance between the emitter 100 and the collector 210 is constant regardless of the material of the fixing part 600 . can be maintained

The non-collecting part fixing part 630 is formed on the upper surface of the collector fixing part 620 . The non-collecting part fixing part 630 is also provided in plurality, and is formed between each of the groove parts 621 .

The non-collecting part fixing part 630 has a substantially plate shape long in the height direction, and a through hole 631 is formed. Fitting grooves 632 are formed above and below the through hole 631 so that the upper and lower ends of the non-collecting part 300 are fitted, respectively.

In the present embodiment, the width of the through hole 631 is formed to be wider than the width of the non-collecting part 300 . This is to prevent the creepage discharge described above. The width of the through hole 631 is formed to be wider than the width of the non-collecting part 300 , so that the air insulating space is formed on both sides of the non-collecting part 300 to maximize the air insulating thickness, thereby preventing creepage discharge.

In addition, since the non-collecting part fixing parts 630 are spaced apart from each other, a space 634 is formed between the non-collecting part fixing parts 630 , and the collector 210 is disposed in this space, and the space between the non-collecting parts 300 . is formed wider than the width of the collector 210 . In other words, the width of the non-collecting part fixing part 630 is smaller than the interval between the groove parts 621 . That is, air insulation spaces are also formed on both sides of the collector 210 . In the same manner as the air insulating space on both sides of the non-collecting part 300 , the air insulating space is also formed on both sides of the collector 210 to maximize the air insulating thickness, thereby preventing creepage discharge.

Meanwhile, a protrusion 633 protruding from the side surface is formed on the upper portion of the non-collecting part fixing part 630 . The protrusion 633 serves as a guide to be easily mounted when the collector 210 is inserted.

A guide groove, which is a space between the protrusions 633 of the adjacent non-collecting part fixing part 630, is formed, and the collector 210 is inserted/removed through the guide groove to facilitate attachment and detachment.

In this case, both sides of the collector 210 may be in contact with the protrusion 633 . That is, the lower end of the collector 210 may be fixedly inserted into the groove 621 , and both sides of the collector 210 may be in contact with the protrusion 633 .

6 is an explanatory diagram for replacing a collector of an ion wind air purifier according to an embodiment of the present invention.

The case 400 has a structure in which the upper and lower sides are open. The lower portion is a passage through which air is introduced through corona discharge, and the upper portion is a passage through which the ion wind is discharged. The case 400 has an open top and bottom structure, and the collector 210 has a lower end inserted into the groove 621 and both sides of the upper end are guided by the protrusion 633, so the collector 210 has a top and bottom detachable structure. has

Specifically, the collector 210 grips the upper end when mounted on the case 400 and then inserts the lower end into the guide groove, which is the space between the protrusions 633 , into the groove 621 , and grips the upper end when detaching. Then, it can be completely separated from the case 400 by pulling it out upwards. Therefore, it has a very simple detachable structure.

Meanwhile, as described above, in the collector module 200 , a plurality of collectors 210 are connected to each other through a connecting member (not shown). At this time, the connection member has a clamp-type terminal at the end like an alligator clip, so the connection between the collectors 210 is simple and modularization is also simple.

Since the collector 210 is a configuration in which particles charged by corona discharge are collected on the surface, the dust collection power is lowered after collecting dust to a certain extent, so it is a consumable item that needs to be replaced and needs to be cleaned or replaced periodically.

In the present embodiment, the collector 210 has a structure in which the lower end is inserted into the groove 621 and the protrusion 633 guides it, so it is convenient to attach and detach it, which makes it easy to replace it with another collector module 200 . That is, it is used for one-time use and maintenance through replacement is easy. Alternatively, since it is convenient to attach and detach, it is removed from the case 400 upwards, washed, and then the lower end is inserted into the guide groove, which is the space between the protrusions 633 , and inserted into the groove 621 , so that easy maintenance is possible.

Accordingly, in this embodiment, the collector 210 may have a lightweight structure to be described later, or the collector 210 may be manufactured using an aluminum plate (or a thin SUS plate), and each collector 210 is a connecting member (eg, a crocodile). clip, etc.). In the case of having a lightweight structure, the collector 210 is more suitable for one-time use, and when used as an aluminum plate or a thin SUS plate, a washing method is more suitable.

7 is a longitudinal sectional view of the collector of the ion wind air purifier according to an embodiment of the present invention, FIG. 8 is a longitudinal sectional view of the non-collecting part of the ion wind air purifier according to an embodiment of the present invention, and FIG. 9 is the present invention is an explanatory diagram of the connection relationship between the non-collecting parts of the ion wind air purifier according to an embodiment of the present invention.

The collector 210 and the non-collecting unit 300 may have a lightweight structure.

In this case, the collector 210 has a structure in which a first conductive member 230 is covered on a light first foam 220 .

Since it is difficult to form a structure when only the thin first conductive member 230 is used to reduce the weight of the collector 210, in this embodiment, the first conductive member 230 is covered with the first foam 220 having a low density. As a result, the structure is very light and easy to form, and it functions as an electrode through which current flows by the first conductive member 230 (refer to (a) of FIG. 7).

In the collector 210 , the first conductive member 230 is covered on the first form 220 , and the first conductive member 230 may form a round 240 from one end of the first form 220 . Here, the round 240 means a protruding shape located at one end of the first form 220 . More preferably, the round 240 means a semicircle having a cross-section having a radius R (see (b) of FIG. 7).

When the round 240 is formed on the collector 210 , the reverse discharge phenomenon is minimized and the dust particle collecting performance can be maximized. In addition, since the round 240 is formed, spark generation may be minimized. Here, the reverse discharge phenomenon refers to a phenomenon in which negative ions travel from the collector 210 to the emitter 100 according to an increase in voltage. When the electric field exceeds a predetermined size, reverse discharge may occur. Since the strength of the electric field on the surface of the round 240 is inversely proportional to R, it is preferable to maximize R as much as possible so that this voltage does not occur.

The non-collecting part 300 has a structure in which the second foam 320 is covered on the electrode. Specifically, in the non-collecting part 300 , the electrode is provided as a second conductive member 310 , and has a structure in which the second conductive member 310 is covered with a second foam 320 .

In addition, since the second foam 320 is covered on the electrode, sparks that may be generated in the electrode are prevented, thereby increasing the dielectric breakdown voltage. When a voltage is applied to the electrode, a spark may be generated at a low voltage. As the voltage is increased and the strength of the electric field is increased, the collection efficiency of fine dust collectors is increased, but there is a problem in that a spark is generated when a voltage is applied. In particular, at the end of the metal, leakage current occurs even below the breakdown voltage, which may consume a lot of energy. In this embodiment, the wood lock is wrapped around the electrode to prevent sparks at the electrode, especially the end, and the breakdown voltage is maximized to collect fine dust. Efficiency is excellent.

Particles are collected in the collector 210 by the voltage difference applied to the emitter 100 and the collector 210 . That is, since the emitter 100 is an anode and the collector 210 is a cathode, positively charged particles are collected in the collector 210 during corona discharge. In addition, particles are collected by the collector 210 by a voltage difference applied to the electrode (the second conductive member 310 ) of the non-collection unit 300 and the collector 210 . Although particles are collected at the end of the collector 210 facing the emitter 100 due to the voltage difference applied to the emitter 100 and the collector 210 , the amount of particles collected may be insufficient by this mechanism alone. Accordingly, when the electrode of the non-collecting part 300 is the same anode as the emitter 100 , most of the particles are collected on the surface of the collector 210 , which is a cathode facing the non-collecting part 300 . The particle collection amount by this mechanism is much greater than the particle collection amount at the end of the collector 210, and as the area of the collector 210 increases, the collection efficiency of ultra-fine particles is increased.

On the other hand, the first foam 220 and the second foam 320 of the collector 210 and the non-collecting part 300 are expanded polystyrene (EPS: expanded polystyrene or Styrofoam), expanded polypropylene (EPP: expanded polyprop), expanded polyolefin (EPO: expanded polyolefin), Woodrock (Woodrock), defron (Deprone, closed cell polystyrene) may be any one.

In addition, the first conductive member 230 and the second conductive member 310 may be a conductive film or an aluminum foil (Al foil). When a conductive film is used, aluminum may be deposited on the PET film.

The electrodes of the plurality of non-collecting units 300 may be connected to each other through lead wires 340 .

The non-collecting part 300 may further include an insulating member 330 to further improve insulating performance.

Excellent insulation performance may be required due to the integrated structure of the collector 210 and the collecting electrode, and in this case, the insulation member 330 may have a structure surrounding the second foam 320 . In this embodiment, the insulating member 330 may be an insulating film, more specifically, may be an insulating film such as a PVC film. When an insulating film is used as the insulating member 330 , it has a double insulating effect along with the primary insulating of the second foam 320 , and has flame retardant and ozone resistance effects.

In order to improve insulation performance, the lead wire 340 may also have an insulating structure, and in this case, the lead wire 340 may be disposed inside the double insulation tube 350 . Here, the double insulating tube 350 may be a heat shrinkable tube or a silicon tube. The double insulating tube 350 and the insulating member 330 may be bonded to each other through high-frequency bonding or ultrasonic bonding. A spark with the sharp end of the collector 210 can be prevented by using the double insulating tube 350 .

On the other hand, in the present embodiment, the case 400 is preferably mounted on a mounting portion fixed to the upper portion of the ceiling or wall when mounted in an indoor space. This is to allow the ion wind discharged from the air purifier to hit the ceiling. Therefore, if the ion wind, which is an updraft, can hit the ceiling, various installation examples can be provided as shown in FIG. 10 . At this time, a plurality of ion air purifiers 1000 for indoor use according to the present embodiment may be connected in series or in parallel to be mounted on a mounting unit fixed to the ceiling or wall of an indoor space, and the mounting unit may be mounted on various types of rods, rails, etc. It can be implemented by configuration.

Due to the lightweight structure of the collector 210 and the non-collecting part 300 , it is easy to fix even when installed on a ceiling or an upper part of a wall, and there is no risk of falling.

As described above, the emitter 100 is disposed below the collector 210, and in the plasma region around the emitter 100, free electrons present in the air are rapidly accelerated to a high speed due to a very strong electric field. It creates positive ions by colliding with air molecules. Positive ions are generated in the plasma region around the emitter 100 and corona discharge moving to the collector 210 occurs. Through this, the ion wind forms an upward airflow, and the dust particles also flow in from the bottom and move upwards.

When the generated cation collides with an oxygen molecule (O2) and dissociates to form an oxygen atom (O), the oxygen atom meets two oxygen molecules to form a three-body collision that produces ozone (O). +O ₂ +O ₂ →O ₃ +O ₂ ) is accompanied, so a large amount of ozone is unavoidable to generate ions.

Since ozone generated in the plasma region has no electrical polarity, it is discharged out of the air purifier along the streamline of the ion wind. That is, there is a problem in that the ozone concentration increases in the indoor space. The ozone concentration inhaled by the human body is preferably 0.03ppm or less.

In summary, when dust collection through corona discharge is used to remove fine dust from indoors, there is a problem in that the concentration of ozone in the indoor space increases. Ozone has the advantage of excellent sterilization/deodorization power, but it is because it adversely affects the human body. In fact, when a person inhales ozone, the pulse rate and blood pressure decrease, and symptoms complaining of dizziness appear. In severe cases, it can cause lung damage, and exposure to the eyes can cause inflammation. In particular, if children with weakened immunity are exposed to ozone for a long time, they may complain of shortness of breath and dizziness, and in severe cases, asthma and chronic respiratory diseases.

11 is an explanatory view of air flow in an indoor space to which an ion wind air purifier according to an embodiment of the present invention is applied.

However, in the present embodiment, the concentration of ozone generated during corona discharge is reduced by the mounting position of the case 400 and the rising airflow of the ion wind. The cause of the decrease in ozone concentration in the indoor space in this embodiment is as follows.

) to carbon monoxide (

) and the self is annihilated. ⓓ Ozone has the advantage of sterilizing and deodorizing air due to its strong oxidizing power. ⓔ Ozone collides with aerosol particles (fine dust, Saharan dust, volcanic ash, etc.) and decomposes. ⓕ The generated ozone is dispersed into the atmosphere as it convections with the air, and its concentration decreases as it diffuses in the atmosphere. This phenomenon is a general property of gases in air and is governed by the transport equation.

In this embodiment, the emitter 100 is disposed below the collector 210 so that the ion wind forms an upward airflow.

The case 400 is mounted on the ceiling or the side wall 500 of the indoor space, and the ion wind discharged upward hits the ceiling and then moves along the wall to increase the residence time. In the process, part of it is extinguished by outdoor sunlight or indoor lighting by mechanism ⓐ.

In addition, the indoor space where the air purifier is installed has a high concentration of fine dust, which in turn destroys ozone. That is, in the case of inorganic fine dust, it disappears by the ⓔ mechanism, and in the case of organic fine dust, it disappears by the ⓒ mechanism.

And since ozone molecules collide with ceilings, walls, furniture, furniture, and the human body, they are further annihilated by mechanisms ⓑ and ⓒ.

That is, when the ion wind is discharged directly into the indoor space like a general air purifier, such as the ion wind is directed downward from the air purifier, the time for ozone to reach the human nose is much shorter, so the ozone concentration is hardly reduced. However, in the case of this embodiment, the ion wind forms an updraft and moves along the wall after hitting the ceiling, increasing the residence time before inhalation into the human body. Ozone has the potential to accumulate if exposed for a long time in an enclosed space.”

In particular, in places where highly toxic carcinogens such as aldehydes and carbon black are generated in high concentrations, such as in grilled restaurants, it is desirable to quickly remove these toxic substances by using an ion air purifier, but the inhaled ozone concentration is at a safe level (0.03ppm). should be less than A corresponding additional research hypothesis is that the sterilization and deodorization effect of ozone by the ⓓ mechanism as well as the effect of removing fine dust in a space with severe fine dust can offset the danger of ozone.

On the other hand, to additionally install an ozone filter to lower the concentration of ozone discharged from the outlet of the air purifier, the above mechanisms ⓑ and ⓒ are used. You need to add a blower. This has a problem in that the manufacturing cost is high and the blowing noise is generated.

Also, in corona discharge, the ozone concentration increases linearly as the current increases, and the speed of the ion wind increases in proportion to the square root of the current. And as the current increases, the number of ions attached to the fine particles increases, so the collection efficiency increases. Therefore, in a given ion air purifier, reducing the current to reduce the ozone concentration is an easy solution, but since the speed of the ion wind is reduced, the air purification amount is reduced and the fine particle collection efficiency is lowered.

That is, in order to increase the efficiency of collecting fine dust, the applied current must be high, but in this case, there is a problem in that the ozone concentration increases. In the present invention, the ozone in the indoor space decreases and disappears before being inhaled into the human body by causing the ion wind to become an ascending air flow and by allowing the ion wind discharged from the air purifier to collide with the ceiling and then move along the wall due to the mounting position of the case 400 . there is In addition, there is no noise because there is no need to install a separate blower. On the other hand, the ozone sterilization and deodorization process is carried out only in the ion air purifier 1000 for indoor use.

The following are the experimental results according to this example.

After operating the ion wind air purifier 1000 according to this embodiment, the indoor ozone concentration was measured. The ozone concentration meter used is UV-106M, and the applied current is 3.15mA. The ozone concentration on the table in the indoor space was measured for about 120 minutes while the indoor space was sealed. The ozone concentration at the outlet of the air purifier was measured for 200 seconds after t1 (64 minutes), and the ozone concentration at the outlet of the air purifier was measured for 200 seconds after t2 (123 minutes). The inlet / outlet concentration of the was measured.

As a result of the experiment, ① the change in the ozone concentration in the indoor space was saturated at 0.02~0.03ppm in 2 hours (3/43 times the city part), and was measured to be 'good' for indoor use. ② The outlet concentration was measured to be 0.04ppm at t1 and 0.05ppm at t2, and the outlet concentration after ventilation was measured to be 0.06ppm. Confirmed. ③ After ventilation, the difference in ozone penetration between the inlet and outlet of the air purifier was found to be 0.02ppm.

From the above experimental results, it is confirmed that the ozone concentration is partially increased due to the change in air flow after ventilation. was measured, and it was confirmed that ozone was not a problem when using the air purifier according to the present invention in an indoor space.
