Description

Simultaneous removal device for ultra fine dust and volatile organic compounds

The present invention relates to a device for simultaneously removing ultrafine dust and volatile organic compounds, and more particularly, to a device for simultaneously removing ultrafine dust and volatile organic compounds contained in polluted air.

Dust is a particulate matter that floats or is blown down in the atmosphere, and it is generated a lot when burning fossil fuels such as coal and petroleum, or from exhaust gases from factories and automobiles.

Dust is divided into total dust (TSP), which is less than 50 µm, and particulate matter (PM), which has a very small particle size, depending on the particle size.

Fine dust is divided into fine dust PM10 with a diameter of less than 10 μm and fine dust PM2.5 with a diameter smaller than 2.5 μm. Moving into the body can adversely affect health.

In particular, the World Health Organization (WHO) has presented air quality guidelines for fine dust since 1987, and in 2013, the International Agency for Research on Cancer (IARC) designated fine dust as a group 1 carcinogen confirmed to be carcinogenic to humans. did

The composition of such fine dust may vary depending on the region, season, and weather conditions in which it is generated.

In general, it is composed of lumps such as sulfate and nitrate formed by the reaction of air pollutants in the air, carbons generated when fossil fuels are burned, black substances formed by agglomeration of soot or smoke, minerals generated from ground dust, etc.

Fine dust composed of these components is generated through a chemical reaction in which sulfuric acid emitted during the combustion of fossil fuels combines with water vapor and ammonia in the atmosphere, or nitrogen oxides from automobile exhaust combine with water vapor, ozone, and ammonia in the atmosphere. do.

Compared to major advanced countries, Korea's fine dust concentration is still high, 1.5 times, 2.1 times, and 2.3 times higher than those of the United States, France, and Paris, respectively.

This is because India's density of India is high, urbanization and industrialization are advanced, so there is a lot of fine dust emission per unit area, and geographical location and weather conditions are not advantageous.

It is an invention that removes dust.

Document 2 is an invention that creates a comfortable indoor environment by removing fine dust in the air through washing and purification while being smeared on the spray particles in which polluted air introduced into the fine dust removal device is sprayed.

Document 3 is an invention for installing a fine dust collector on the top of a vehicle or installing it inside a house to remove fine dust contained in the air and then discharging clean air to the outside.

Document 4 is an invention that effectively adsorbs harmful substances in the air by maximizing the contact area between indoor air and washing water flowing into a purification device for a wet air purifier.

Hereinafter, with reference to the accompanying drawings, the ultrafine dust and volatile organic compound simultaneous removal device 1 (hereinafter, referred to as “simultaneous removal device 1”) according to the first embodiment of the present invention will be described in detail. Let me explain.

1 is a block diagram showing the configuration of an apparatus for simultaneously removing ultrafine dust and volatile organic compounds according to a first embodiment of the present invention, and FIG. 2 is a perspective view schematically showing an electric dust collector according to a first embodiment of the present invention. , Figure 3 is a schematic diagram showing the arrangement of the ionizer, the medium filter and the mesh filter according to the first embodiment of the present invention, Figures 4a to 4d are coated glass according to the first embodiment of the present invention and volatility by the ultraviolet irradiator It is a diagram showing the removal process of organic compounds.

Referring to FIG. 1 , the simultaneous removal device 1 according to the first embodiment of the present invention includes an electric dust collector 10, an ionizer 20, and a medium to simultaneously remove ultrafine dust and volatile organic compounds (VOCs). It is configured to include a filter 30 , a mesh filter 40 , a coated glass 50 , and an ultraviolet irradiator 60 .

In addition, the simultaneous removal device 1 according to the first embodiment of the present invention can be applied indoors or outdoors, the length and width of the components can be adjusted.

Referring to FIG. 2 , the electrostatic precipitator 10 is configured with an ACF bundle 11 that guides polluted air containing ultrafine dust and volatile organic compounds to move in a direction perpendicular to the direction in which it flows from the outside.

Here, the contaminated air is moved toward the ACF bundle 11 by a blowing fan (not shown), and the ACF bundle 11 is made of a plurality of active carbon fibers (ACF) extending in a right angle direction. and the external polluted air flowing into the plurality of activated carbon fibers (11-1, 11-2, 11-3, 11-4, 11-5) is moved in a right angle direction and guided to the ionizer (20).

At this time, since the ACF bundle 11 is made of activated carbon fiber used as an adsorbent, it is possible to filter by adsorbing ultrafine dust contained in polluted air.

A plurality of activated carbon fibers (11-1, 11-2, 11-3, 11-4, 11-5) to allow external polluted air to flow in and to move external polluted air to the ionizer 20 For this purpose, it is spaced at the same or different intervals from the adjacent activated carbon fibers to form a movement path of external polluted air.

The electrostatic precipitator 10 not only induces movement of the polluted air to the ACF bundle 11, but also provides a negative charge to the ultrafine dust so that the ultrafine dust has an electric charge, and the power supply 12 is configured.

Here, the power source 12 applies a negative voltage to the ACF bundle 11 so that ultrafine dust moving along the ACF bundle 11 has an electric charge, and the negative voltage is applied to the ACF bundle 11 This is possible because the ACF bundle 11 is made of activated carbon fibers with excellent electrical conductivity.

Referring to FIG. 3 , the ionizer 20 coarsens the ultrafine dust by coupling the ions of the positive electrode to the ultrafine dust included in the polluted air passing through the electric dust collector 10 .

In addition, the ionizer 20 crosses the movement direction of the polluted air passing through the electrostatic precipitator 10 in order to coarsen the ultrafine dust without interfering with the movement of the polluted air passing through the electrostatic precipitator 10 . It is arranged to generate ions of the anode in the direction, and may be implemented as a pair of ionizers 20-1 and 20-2 in order to maximize the coarsening efficiency of ultrafine dust.

In addition, the ionizer 20 may be provided with a discharge needle 21, which is a component for generating positive ions, on one side.

It is preferable that the discharge needle 21 generate positive ions in a direction transverse to the movement direction of the polluted air passing through the electrostatic precipitator 10 according to the arrangement direction of the ionizer 20 .

Furthermore, a plurality of discharge needles 21 may be provided to generate ions of the anode as well as ions of the cathode. That is, one discharge needle 21 may generate positive ions, and the other discharge needle 21 may generate negative ions.

As described above, if the discharge needle 21 is implemented to generate positive and negative ions, if the power supply 12 applies a positive voltage to the ACF bundle 11 , the ultrafine dust is charged by the positive electrode charge. In the case of having a , it is to coarsen the ultrafine dust by binding the ions of the negative electrode to the ultrafine dust.

Meanwhile, the ultrafine dust coarsened by the ionizer 20 may have a particle size of 1.0 to 3.0 μm.

The medium filter 30 filters the coarsened ultrafine dust contained in the polluted air passing through the ionizer 20 .

The medium filter 30 is preferably processed into a filter capable of filtering ultra-fine dust of 1.0 to 3.0 μm coarsened by the ionizer 20 .

The mesh filter 40 filters harmful microorganisms contained in the polluted air passing through the medium filter 30 .

Here, the harmful microorganisms may be harmful substances harmful to the human body, such as house dust, mites, viruses, mold, and the like.

Accordingly, the mesh filter 40 is preferably processed into a filter capable of filtering harmful microorganisms.

In addition, the mesh filter 40 may be processed in the form of an antibacterial non-woven fabric filter to have antibacterial activity against harmful microorganisms.

As such, the mesh filter 40 has antibacterial activity because the antibacterial material dispersed in a fine particle size on the surface of the antibacterial nonwoven filter inhibits the growth of harmful microorganisms on the surface to prevent secondary contamination.

Referring to FIGS. 4A to 4D , the coated glass 50 is coated with a mixture 55 for removing the volatile organic compounds contained in the polluted air passing through the mesh filter 40 on the surface.

Here, the polluted air passing through the mesh filter 40 may contain oxygen and moisture as well as volatile organic compounds, and the mixture 55 includes titanium dioxide (TiO ₂ ), copper (Cu) and aluminum (Al) at least. may include

In the mixture 55, titanium dioxide is activated by ultraviolet rays (UV) irradiated from the ultraviolet irradiator 60 to generate electrons and holes, and oxygen and moisture in the polluted air are converted into radicals (or hydroxyl groups) using electrons or holes. and volatile organic compounds are removed from the polluted air by radical oxidation.

The UV irradiator 60 removes volatile organic compounds, oxygen, and moisture contained in the polluted air passing through the mesh filter 40 , and the process is as shown in FIGS. 4A to 4D .

Referring to FIG. 4A , the polluted air passing through the mesh filter 40 is in a state in which ultrafine dust has been removed by the medium filter 30 of the previous stage, and the volatile organic compounds (A), oxygen (B) and moisture (C) includes

Referring to FIG. 4B , when the polluted air passes through the mesh filter 40 , the UV irradiator 60 irradiates the coated glass 50 with UV light to induce the mixture 55 to generate electrons and holes.

Here, the UV irradiation time of the UV irradiator 60 is preferably when the polluted air passes through the mesh filter 40, but the volatile organic compound process can be omitted depending on the fast movement speed of the polluted air, It is more preferable to irradiate the ultraviolet rays from the time they flow into the electrostatic precipitator 10 .

Referring to FIG. 4C , oxygen and moisture contained in polluted air are converted into radicals (D) by electrons or holes.

Here, the radical (D) refers to an OH- radical generated as the titanium dioxide of the mixture 55 is activated by ultraviolet rays.

Referring to FIG. 4D , the volatile organic compounds contained in the polluted air are decomposed by the oxidation reaction of radicals (D) and removed from the polluted air.

Accordingly, the air passing through the volatile organic compound removal process of the coated glass 50 and the UV irradiator 60 may be clean air from which ultrafine dust and volatile organic compounds are all removed.

Based on the above components, the simultaneous removal device 1 of the present invention is capable of simultaneously removing ultrafine dust and volatile organic compounds contained in polluted air.

In addition, the simultaneous removal device (1) of the present invention is the material of the electric dust collector (10), the medium filter (30) and the mesh filter (40) in order to reduce the ultrafine dust contained in the external polluted air and at the same time reduce the noise and The structure may be preset.

And the simultaneous removal device (1) of the present invention can be manufactured as a device having a standard that reduces ultrafine dust of NRC 0.7 or more and PM2.5 or less by 30% or more.

Hereinafter, an apparatus for simultaneously removing ultrafine dust and volatile organic compounds according to a second embodiment of the present invention will be described in detail with reference to the accompanying drawings, focusing on parts that do not overlap with the first embodiment.

5 is a side cross-sectional view schematically showing an electric dust collector according to a second embodiment of the present invention, and FIG. 6 is a partially enlarged view of a part of the electric dust collector according to the second embodiment of the present invention.

Referring to FIG. 5 , the arrangement method of the ACF bundle 11 in the electric dust collector 10 may be different from that of the first embodiment.

As a specific example, the first activated carbon fiber (11-1), the second activated carbon fiber (11-2), the third activated carbon fiber (11-3), the fourth activated carbon fiber (11-4) and the fifth Activated carbon fibers (11-5) may be arranged in a higher position in order.

As a specific example, the first horizontal activated carbon fibers 11-1a may be disposed on a virtual horizontal line and disposed at the lowest position, and the remaining second horizontal activated carbon fibers 11-2a, the third number Balanced activated carbon fibers (11-3a), fourth horizontal activated carbon fibers (11-4a) and fifth horizontal activated carbon fibers (11-5a) in the order of the first horizontal activated carbon fibers (11-1a) As the height difference increases, the fifth horizontal activated carbon fibers 11-5a may be disposed at the highest position.

On the other hand, the vertical activated carbon fiber (11-b) is made of different lengths, unlike the first embodiment, the length is opposite to one side implemented in connection or integral with the horizontal activated carbon fiber (11-a) The height of the other side may be the same length as each other.

As a specific example, the first vertical activated carbon fiber (11-) implemented in connection with or integrally with the first horizontal activated carbon fiber (11-1a) disposed at the lowest position among the horizontal activated carbon fibers (11-a) (11-a) 1b) is made longer than the other vertical activated carbon fibers (11-b), the fifth vertical type activated carbon fiber (11-5a) and the fifth vertical type that is arranged in the highest position or integrally implemented The activated carbon fibers 11-5b are made shorter than other vertical activated carbon fibers 11-b, so that the other side of the vertical activated carbon fibers 11-b may be all arranged at the same height.

Referring to FIG. 6 , the electric dust collector 10 reinforces the connection structure of the activated carbon fiber when one side of the horizontal activated carbon fiber 11-a and one side of the vertical activated carbon fiber 11-b are connected. A reinforcing member 13 for doing so may be configured.

It may be preferable that the reinforcing member 13 is made of a flexible material (eg, silicone, rubber, etc.) for reinforcing the connection structure from external impact.

In addition, the reinforcing member 13 may be formed with a first inlet groove (not shown) through which one side of the horizontal activated carbon fiber 11-a can be drawn into one side to implement a connection structure of the activated carbon fiber, A second inlet groove (not shown) through which one side of the vertical activated carbon fiber 11-1b can be drawn may be formed on the other side.

And the reinforcing member 13 not only reinforces the connection structure of the activated carbon fiber, but also increases the movement speed of the polluted air in the vertical activated carbon fiber 11-b than in the section of the horizontal activated carbon fiber 11-a. As much as possible, a part may be bent.

As a specific example, one side of the second reinforcing member 13-2 may be bent to have a thickness of the first width 13a while surrounding the lower portion of the vertical activated carbon fiber 11-2b. In addition, the other side of the second reinforcing member 13-2 has a thickness toward the other side of the second vertical activated carbon fiber 11-2b while surrounding the side of the second vertical activated carbon fiber 11-2b. It may be bent to have a thickness of the second width 13b by increasing it.

That is, the thickness of one side of the reinforcing member 13 is the same, but the thickness of the other side may increase toward the other side of the vertical activated carbon fiber 11-b.

And since the width of the second width 13b is larger than the first width 13a, the first section width ( 11a), the second section width 11b, which is the width between the second reinforcing member 13-2 and the first vertical activated carbon fiber 11-1b, may be reduced.

Accordingly, the movement speed of the polluted air in the section of the first and second vertical activated carbon fibers (11-1b, 11-2b) than in the section of the first and second horizontal activated carbon fibers (11-1a, 11-2a) can be increased.
