Description

Fine Dust Removal Device using Static

The present invention relates to an apparatus for removing fine dust using static electricity, and more specifically, to remove fine dust through ion bonding by passing air containing fine dust in which a large amount of metal ions and salt ions pass through an ionization solution. Furthermore, the present invention relates to a fine dust removal device capable of keeping the air quality of the emergency room or intensive care unit where the respirator is sensitive and clean by additionally removing fine dust through electrostatic attraction.

As the industry develops, the problem of air pollution due to various soot is getting more and more serious. In particular, as China develops into a full-fledged industrialized country, various pollution problems are serious. However, various pollutants from China, especially fine dust, continue to cross over to Korea in a whistle wind, and the Meteorological Agency announces the concentration of fine dust several times a day.

 Fine dust is a small substance that is invisible to our eyes and is a particulate matter with a diameter of 10 μm or less that floats or scatters in the air for a long time. Fossil fuels such as coal and petroleum are combusted, or come from exhaust gases from manufacturing and automobile fumes. They are adsorbed into the lungs through bronchial tubes and cause various waste diseases.

Fine dust is composed of ionic components such as nitrate (NO3-), ammonium (NH4 +), sulfate (SO42-), carbon compounds, and elements compounds. The World Health Organization (WHO) Black carbon (BC) from diesel has been designated as a primary carcinogen. When exposed to fine dust for a long time, the immunity is rapidly lowered and can be exposed to various diseases such as cardiovascular disease, skin disease, eye disease, as well as respiratory diseases such as cold, asthma and bronchitis. In particular, ultrafine dust having a diameter of 2.5 μm or less easily penetrates deep into the bronchus and lungs in the human body and causes various diseases in the bronchus and lungs.

Meanwhile, the World Health Organization (WHO) has proposed air quality guidelines for fine dust (PM10, PM2.5) since 1987, and in 2013, the International Agency for Research on Cancer under the World Health Organization (IARC). ) Was designated as a group 1 carcinogen (Group 1) confirmed to be carcinogenic to humans.

In addition, the housing 10 is made of a material having a strong durability and chemical resistance, such as acrylic, is suitable for long-term operation of the fine dust removal device.

In addition, the air injection unit 100 is a place where the air containing the fine dust is injected, specifically for this purpose includes a support 110 and the fan 120.

The support unit 110 extends to the bottom at regular intervals along the bottom circumference of the housing 10, and the shape of the support 110 may be any shape that can support the housing 10, such as a plate shape or a column shape. The support 110 may be extended in plural to provide a function of more securely supporting the housing 10.

The fan 120 is located at one side of the bottom of the housing 10, and provides a function of sucking air into the housing 10 including fine dust due to the driving of the fan 120.

Furthermore, the first chamber 200 is a place where the fine dust is removed through the first filter 230 soaked in the ionization solution while the air introduced through the air inlet 100 flows. ), A first guide 220, a first filter 230, and a second guide 240.

The air inlet 210 is formed through one side portion of the bottom surface of the housing 10 in which the fan 120 is installed. The air inlet 210 may be stably mounted in a smaller size than the fan 120 to stably mount the fan 120. Because it is preferred. This air inlet provides the function of a passage for the air sucked by the fan 120 to enter the first chamber 200.

The first guide 220 stands as a predetermined height around the air inlet 210 with a diameter smaller than that of the housing 10, and may have a pipe shape with an open top surface. At this time, since the air is a fluid, it is swirled by the driving of the fan 120 and enters into the first chamber 200 in an upward direction. When the shape of the first guide 220 is a square pipe, the fluid flows smoothly. Air may not reach the second chamber 400 (which is located in the upper portion of the housing 10, which will be described later) after passing through the first chamber 200. Therefore, the first guide 220 has a cylindrical pipe shape, so that the fluid may rise smoothly. The first guide 220 may be made of the same material or different materials as the housing 10.

The first filter 230 is seated in the circumferential space between the inner wall of the housing 10 and the outer wall of the first guide 220. The first filter 230 is soaked in an ionization solution containing sodium chloride, that is, a component of fine dust. Nitrate (NO ₃ ⁻ ), sulfate (SO ₄ ^2- ) and ammonium salt (NH ₄ ⁺ ) can be removed.

Referring to FIG. 2, the air (air containing fine dust) that has risen on the inner wall of the first guide 220 through the air inlet 210 is spaced apart from the first guide 220. The second guide 240 (the detailed description thereof will be described later) is passed down the top of the first guide 220 to the outside of the first guide 220 again, the air is the first filter 230 active ingredient, sodium chloride (NaCl) and the nitrate component of the particulate matter as it passes through the solution of the ionized (NO ₃ ^-), sulfate (SO ₄ ^2-), ammonium salt (NH ₄ ⁺⁾ in the fine as to the ionic bonds air Dust can be removed. That is, specifically, sodium cation, sodium nitrate, and sulfate of sodium chloride may be combined and removed, and chloride ions may be ion-bonded with ammonium salt to form ammonium chloride (NH ₄ Cl), which is a white sediment, to remove ammonium salt. The air from which the fine dust is removed rises again through the first filter 230 and moves to the second chamber 400 through the air distribution hole to be described later, which will be described later.

The first filter 230 that performs this function is preferably made of a porous porous material formed with pores for air to pass through, for example, may be made of a material having visible pores such as a scrubber, sponge, or fine It can be made of plastic resin (silicon or PVC) with pores.

3 is an exploded perspective view showing the laminated structure of the first filter 230 of the present invention.

Referring to FIG. 3, the first filter 230 may form a laminated structure including an upper filter and a lower filter made of the same or different foamed porous materials. For example, the upper filter may be a sponge or the lower filter. It may be made of a loofah, or as shown in Figure 3 by varying the shape of the porous porous material of the upper filter and the lower filter to increase the area of the first filter 230 is in contact with the outer wall of the first guide 220 by air The area that can contact the first filter 230 may be larger.

Furthermore, the upper layer filter is soaked with an ionization solution, and the lower layer filter includes a coherent substance that causes the salt of fine dust and the sodium chloride in the ionization solution to aggregate, and the salt of the fine dust ionizes the ionization solution with the upper layer filter. By the lower layer filter, the ion binder aggregates and is filtered by the first filter 230, thereby improving the removal efficiency of fine dust.

In this case, the first filter 230 may be provided to have a shape different from that of FIG. 3 since the embodiment is illustrated in FIG. 3.

Furthermore, referring to the second guide 240 described above, the second guide 240 has a larger diameter than the first guide 220 in a closed state of the first guide 220 to be spaced apart from the first guide 220. It is supported on the filter 230 to surround the first guide 220 at a predetermined interval, so that the shape of the second guide 240 also has a cylindrical shape to correspond to the shape of the first guide 220, the flow of air Is preferred. As described above with reference to FIG. 2, the second guide 240 includes a first guide through which air rises to allow the air to pass through the first filter 230 in the description of the air flow of the fine dust removing device of the present invention.

At this time, the air distribution hole is formed by penetrating one side of the partition wall, the air in the first chamber 200 is an air distribution hole for rising to the second chamber (400). In order for the second chamber 400 to secondaryly remove fine dust in the air, the second chamber 400 is formed by penetrating the second filter 410 and the side surface of the second chamber 400. It may include an air outlet 420 for discharging.

As shown in FIGS. 1 and 2, the second filter 410 is positioned around the air distribution hole, and may stand up at a predetermined height from the air distribution hole to form a pipe shape. The second filter 410 performs a function of removing fine dust by electrostatic attraction. Specifically, the second charger 414 and the second charger 414 contacting the first charger 413. By the friction of the first and second electrical charge is generated by the electrostatic attraction can be additionally removed metal ions and salts forming the fine dust.

As such, the second filter 410 may include a driving unit for rotating the first charging unit 413 so that the first and second charging bodies may be rubbed. ) And a plurality of first electrifications 413 extending outward in a pinwheel shape at an end of the shaft 411, and a second electrification 414 is provided with the first electrification ( It may be formed to stand up to the first charged material 413 wrapped around the motor 412 to contact the 413.

In this case, it is said that the first charged material 413 extends outward in a pinwheel shape at the end of the shaft 411, and the vane wings made of the first charged material 413 are preferably provided with at least two or more. Also, although not shown in FIGS. 1 and 2, the larger the contact portion between the end of the vane wing and the inner circumferential surface of the second electrification 414, the greater the electrostatic attraction may occur, resulting in higher fine dust removal efficiency. The size of can be made larger than shown in the figure.

The first and second electrifications 413 and 414 may be made of a cloth material. For example, the first electrification 413 may be made of polyester fiber, and the second electrification 414 may be made of fur. When the two fibers are rubbed with each other, a charging phenomenon occurs, and they have different charges (that is, positive charges and negative charges) .As a result, the positively charged battery has fine dust metal ions and the negatively charged battery. There is a fine dust salt, such as nitrates and sulfates can be attracted by the electrostatic attraction to remove the fine dust. Therefore, the first and second charges further filter out fine dust not filtered through the first filter 230 to discharge clean air through the air outlet 420.

In addition, the shaft 411 of the driving unit may be provided by being wrapped by the porous medium 416, wherein the porous medium 416 is a fine dust aggregate contained in the air passing through the first filter 230 (which It refers to the result of agglomeration of the ionized solution and the salt of the fine dust, which is filtered by the first filter 230, but may not be filtered out of the aggregate may be included in the air passing through the first filter 230.) It is made of a material such as a non-woven fabric that performs the function of filtering the air, and the air passing through the porous medium 416 passes through the first and second major bodies, so that fine dust is filtered once more by electrostatic attraction. .

Further, a third charger 415, which is another charger, may be further provided on one side of the outer circumferential surface of the second charger 414. The third charger 415 may be formed of a material of the second charger 414. It is preferable that the friction is made of any one of nylon, cotton, silk, PVC which is a material that is easily generated. The third charged material 415 generates positive or negative charges by the second charged material 414 that is in friction with the first charged material 413. For example, the first charged material 413 and the second charged material are generated. When the first electrical charge 413 is negatively charged and the second electrical charge 414 is positively charged by the friction of the entirety 414, the third electrical charge 415 is negatively charged to the first electrical charge 413. As a result, it is possible to additionally remove fine metal ions that could not be removed. In addition, the static electricity is characterized by the fact that the surface is rougher and more contaminated, so that the first, second, third charges (413, 414, 415) has a large surface area and has a contaminated or oxidized surface. More preferably).

The third charged material 415 generates an electrostatic attraction due to friction with the second charged material 414, through which metal ions and salts of fine dust are additionally removed to further maximize the fine dust removal efficiency. have.

In addition to the above-described configuration, since the fine dust removal efficiency is reduced when the ionization solution soaked in the first filter 230 is reduced, the fine dust removal apparatus of the present invention may further include a structure for spraying the ionization solution. A description thereof will be given below with reference to FIG. 4.

When the ionization solution in the first filter 230 is evaporated it may further include a structure for spraying the ionization solution.

To this end, the fine dust removing apparatus of the present invention may include a moisture detection sensor 250, the injector 260, the injection drive unit 270.

The moisture sensor 250 is provided at one side of the injector 260 to be described later, and provides a function of measuring the amount of moisture of the first filter 230. The moisture sensor 250 measures the amount of the ionization solution (that is, the amount of water) of the first filter 230, and the injection driver 270 (which will be described later) according to the measured value is the ionization solution. It provides a function to determine whether the injection of. At this time, the reference of the amount of water to determine whether the injection may be set in advance.

When it is determined whether the injection by the injector 260 is to inject the ionization solution toward the first filter 230. At this time, it is a matter of course that the plurality of injectors 260 may be installed in the first chamber 200 (that is, a plurality of injectors may be installed on the inner circumferential surface of the housing 10).

The injection driving unit 270 determines whether the injector 260 is driven according to the amount of moisture when the amount of moisture is measured by the moisture detection sensor 250.
