In contrast to smog and dust, fine dust is divided into general fine dust and ultrafine dust. General fine dust is less than 10 micrometer, but it is one tenth of the thickness of hair. Ultrafine dust is less than 2.5 micrometer in diameter, which is only one-thenth of the thickness of hair. It is a mixture of heavy metals and harmful substances It is not only visible, but also visible to the naked eye. Especially, 47% of the total micro dust measured on the Korean peninsula, 41% of the domestic industrial pollution, and 41% of the vehicle soot are increasingly frequent, and various diseases caused by fine dust are increasing rapidly.

In the following description of the present invention with reference to the accompanying drawings, the same components are denoted by the same reference numerals regardless of the reference numerals, and redundant explanations thereof will be omitted. In the following description of the embodiments, a detailed description of related arts will be omitted if it is determined that the gist of the embodiments may be unnecessarily blurred.

1 is a block diagram showing a schematic configuration of a fine dust removing apparatus using a line segment electric field according to an embodiment of the present invention.

Referring to FIG. 1, a fine particle removing apparatus 100 using a line electric field includes an ionizing unit 101, a dust collecting unit 103, a power source unit 105, a controller 107, an air heating unit 115, a sterilizing unit 129 And an electron-emitting portion 131. The electron-

The ionization unit 101 ionizes the negative (-) and positive (+) ions in accordance with the negative / positive ionization sequence of foreign substances such as dust contained in the incoming air. The ionization part 101 includes an ionization part (EI) 109 and a separation part (Radiation Wire of Positive Ionizer) 111.

The anionization unit (EI) 109 adsorbs electrons to the fine dust by an electron generating device to anionize the fine dust. The cationization unit (RPI) 111 is a strong electric field that absorbs electrons in the fine dust, and releases the electrons to the ground to be cationized.

Fine dust is a mineral. Organic matter, and metal elements, which have different ionization degrees, and are divided into an element that is liable to be a cation and an element that is liable to be an anion. Therefore, it is impossible to ionize all the fine dusts by the configuration of the negative ionization portion EI as in the conventional art. In the embodiment of the present invention, both the anionizing unit (EI) 109 and the cationizing unit (RPI) 111 are separated and the fine dusts are all made negative / cationized to increase the fine dust ionization rate, can do.

The dust collecting unit 103 collects the (+) ion or the (-) ion of the fine dust that is negative / cationized in the electric field by moving the electrode in a specific direction and attaching it to the adhesive filter 125. The dust collecting part 103 is composed of a wire mesh type line electric field and an adhesive filter 125 for collecting ionized super fine dust particles. Conventionally, a parallel plate dust collecting plate requires a high voltage in order to generate an electric field, and the collection effect is not high due to a constant electric field intensity distribution. The electric field strength of the wire mesh type according to the embodiment of the present invention is such that a strong chaotic electric field diverges super fine dust particles even at a low voltage, so that the velocity is reduced and vortexed to be easily collected in the adhesive filter.

Specific configurations of the ionization part 101 and the dust collection part 103 will be described with reference to Figs. 2 to 6. Fig.

The power supply unit 105 supplies a voltage to the ionization unit 101 and the dust collection unit 103. The controller 107 controls the operation of the power supply unit 105 and controls the voltage applied to the ionization unit 101 and the dust collection unit 103 by the power supply unit 105. In addition, the power supply unit 105 may alternately change 10 to 30 times / sec (+) and (-) as well as a DC voltage to supply an alternating current voltage, that is, an alternating direct current voltage PAEF (Pulse Alternative E-Field) We add more features of supply method. The controller 107 can output a control signal for turning on and off the voltage applied to the ionization unit 101 and the dust collection unit 103 and for controlling the voltage from the power supply unit 105 to the power supply unit 105.

And is adsorbed to the dust collecting part 103 at a maximum while preventing negative / cationized fine dust from being neutralized.

FIG. FIG. 6 is an exploded perspective view of an apparatus for removing fine dust according to another embodiment of the present invention. FIG. 6 is a perspective view illustrating a dust collecting unit in which cationized super fine particles are collected in a line segment electric field.

2, the fine dust removing apparatus 100 includes a first dust filter 113, an air heating unit 115, a fan 117, a second dust filter 119, an anionization unit (EI) 109, a cationizing unit (RPI) 111, an adhesive filter 125, a dust collecting unit 103, a third dust filter 127, a sterilizing unit 129, Generator (EIG)

The first dust filter 113 primarily removes external dust and prevents contamination and electrical shorts due to dust adhering to the anionizing unit (EI) 109, the cationizing unit (RPI) 111, and the dust collecting unit 103 do. The first dust filter 113 may include a deodorization filter (not shown).

The air heating unit 115 heats the air introduced into the fine dust removing apparatus 100, thereby increasing the fine dust ionization rate. The heater 115 may be a quartz tube heater. The super fine dust that receives the thermal energy by the heater 155 becomes an excited state which is liable to be ionized, so that the ionization rate is rapidly increased. On the basis of this principle, the air heating unit 115 is turned off when the temperature of the air is relatively low and in the summer when the temperature is relatively high. On the other hand, when the temperature is relatively low, Thereby increasing the ionization rate and improving the fine dust removing function.

The blower 117 is adjustable in air volume of 1 to 3, 3 to 5, and 5 to 8 m ³ / min, and is realized as low noise at bedtime. The blower 117 is disposed inside the fine dust removing apparatus 100. The air blower 117 sucks the outside air of the fine dust removing apparatus 100 into the fine dust removing apparatus 100 to form an anionizing unit (EI) 109, a cationizing unit (RPI) 111, a dust collecting unit 103, And passes through the adhesive filter 125 and flows air so as to be discharged to the outside of the fine dust removing apparatus 100. The blower 117 may include a motor (not shown) generating a rotational force and a blowing fan (not shown) rotated by a motor (not shown).

The second dust filter 119 secondarily removes the external dust that has passed through the first dust filter 113 to prevent contamination and electrical shorting due to dust on the cationizing part (RPI) 111 and the dust collecting part 103 do. The ionization part 101 and the dust collection part 103 can maintain electrical safety and exhibit their performance through the first dust filter 113 and the second dust filter 119. The second dust filter 119 may include a deodorization filter (not shown).

The anionization unit (EI) 109 can use low power (e.g., AC 220 Volt, 0.5 Watt). The anionization unit (EI) 109 adsorbs electrons to the fine dust to thereby become anion. The anionization (EI) 109 is optimized in configuration and placement to create a homogenous anionic distribution when the fine dust is anionized.

The anionization unit (EI) 109 includes a carbon brush 133 for ionizing molecules in air to generate electrons (e-). The carbon brush 133 serves to stably generate a larger amount of electrons (e) stably in the air, and such electrons (e) are adsorbed on the fine dust to increase the anionization rate of the fine dust.

The positive ionization part (RPI) 111 includes a positive electrode and a negative electrode, which are formed so that a plurality of fine needles are radially opposed to each other. The positive electrode is grounded and the negative electrode is charged with a negative voltage to provide electrical safety. The electrons are absorbed and then discharged to the ground to be cationized. The electric field of the cationizing unit (RPI) 111 absorbs and ionizes electrons according to the ionization sequence of the fine dust. Due to the fine needles formed on the positive and negative electrodes of the cationizing part (RPI), a strong converging / diverging line electric field is formed around the fine needle, and in particular, the electric field strength is maximized at the fine needle tip part. As a result, electrons can be effectively absorbed from the fine dust and can be discharged to the ground. The cationizing part (RPI) 111 increases the ionization efficiency of the fine dust that is cationized according to the ionization sequence among various various fine dusts, thereby increasing the efficiency of removing the dust from the dust collecting part 103.

The dust collecting unit 103 includes at least one first mesh network 121 and at least one second mesh network 123. Since the first mesh network 121 and the second mesh network 123 form a complicated convergence / divergence electric field of the chaos generated between the respective line segments in the mesh by the DC voltage, the ionized fine dust is reduced in speed and / It is vortexed and adsorbed abruptly on the adhesive filter. All of the first mesh network 121 and the second mesh network 123 may use a Lotus Effect Mesh. Lotus effect mesh is similar to water-repellent effect because special material is coated on mesh and dust or water easily falls off. So dust or moisture coated on mesh is alternately applied by DC voltage (Pulse Alternative E-field) And is collected by the filter 125 so that the mesh network is always clean, so that the electric field generating effect is enhanced. At this time, since the first mesh net 121 is charged to the negative pole and the second mesh net 123 is grounded to the (+) polarity ground to indicate " zero voltage " Ensure that electrical safety is maintained internally and externally while maintaining safe chaotic field effects.

As shown in FIG. 3, the first mesh network 121 and the second mesh network 123 are disposed so as to be parallel to each other at regular intervals to generate a strong chaos segment electric field with a structure that is not resisted by the air flow path.

4 (a) is a cross-sectional view of a string type electric field intensity and density, and FIG. 4 (b) is a cross-sectional view of a parallel plate electric field intensity and density. The line electric field forms a concentration / divergence field strength and density several thousand times stronger than the parallel plate electric field. The more string lines, the stronger the concentration and divergence of the electric field. Therefore, a strong convergence / divergence Chaos electric field can be obtained without using a high voltage as in the prior art.

5, the negative / cationized fine dust introduced between the first mesh net 121 and the second mesh net 123 decreases in speed due to strong electric field intensity up / down / right / left / Vortices are generated and adsorbed to the first and second mesh screens 121 and 123 by the adhesive filter 125 according to the sign of ionization.

At this time, the (-) ionized fine dust is adsorbed to the second mesh network 123, that is, the (+) mesh network adhesive filter, and the (+) ionized fine dust is adsorbed to the first mesh network 121 -) adsorbed on the mesh network adhesive filter.

The first mesh network 121 and the second mesh network 123 are detachably installed with an adhesive filter 125 between mesh networks that generate a line segment electric field. Adhesive filter 125 may be a non-toxic, non-toxic, viscous, special liquid applied filter, and in one embodiment may be an appropriate concentration of glycerin (C3H5 (OH) 3) cohesive filter. (-) ionized fine dust and (+) ionized fine dust adhere to the adhesive filters 125 of the first mesh net 121 and the second mesh net 124, respectively.

The first mesh network 121, the second mesh network 124, and the adhesive filter 125 are all installed in a direction parallel to the air blowing direction in the fine dust removing device to obstruct the air flow path in the fine dust The ionized fine dust can be adhered to the surface without adhering thereto.

Conventionally, the fine dust was negative / cationized and then collected by a dust collecting plate, and then water was spilled on the dust collecting plate to form a water film, and the fine dust was washed out with water. Therefore, there is a safety risk due to the use of electricity and water. On the other hand, the adhesive filter system according to the embodiment of the present invention is safe because it does not use water, and the adhesive filter 125 is arranged in parallel between the mesh meshes generating the line segment electric field, . In addition, the adhesive filter 125 is detachable and is made of a glycerin material, so that the adhesive can be kept moist and sticky even after a long period of time.

The fine dust particles ionized in the dust collecting section 103 are not only adsorbed by the adhesive filter 125 but also partially adsorbed to the mesh network by an electric field. The DC voltage is changed 10 to 30 times / sec (+) and negative (-) sign by the control unit 107 in order to secondarily adhere the attracted fine dust to the adhesive filter 125, All of the fine dust is removed and reattached to the adhesive filter 125. Since only the adhesive filter is exchanged, the mesh maintains cleanliness without any cleaning, effectively generating the electric field of the line.

This PAEF (Pulse Alternative E-Field) method improves the dust collecting effect and is used to remove fine mesh dust.

The third dust filter 127 removes residual external dust that has passed through the dust collecting section 103 and sterilizes the ultraviolet C (UV-C) in the sterilizing section 129 to sterilize bacteria and pathogens, .

The electronic ion generator (EIG) 131 further includes a function of generating negative ions (e-) to remove fine dust from the electrons and to maximally diffuse negative ion electrons into sterilized clean air, thereby discharging purified negative ion air.
