Description

A DUST COLLECTOR

The present invention relates to a dust collecting apparatus, and more particularly, to a dust collecting apparatus capable of collecting harmful substances in the air.

Radon is a radioactive element resulting from the radioactive decay of uranium and thorium, a decay product of radium. It is a colorless, odorless inert gas that can be naturally generated and agglomerated anywhere in the geological environment (rock, soil, groundwater).

Radiation decay refers to the collapse of one element and the loss of protons, neutrons, electrons, etc., resulting in decomposition into other elemental forms, which occurs spontaneously.

Radium loses two protons and neutrons as longevity, and the two protons and neutrons that are lost are called alpha particles. Radiation decay includes alpha decay, beta decay, and gamma decay. Elements that emit alpha, beta, and gamma rays are called radioactive atoms (Ball, 1991).

Of the natural radioactive elements, U-235, Th-232, and U-238 produce three isotopes of Rn-219, Rn-220, and Rn-222 in each decay series.

Rn-219 has a very short half-life (about 3 seconds), is calculated from the decay series of U-235, and accounts for 0.7% of natural uranium. Therefore, the amount of Rn-219 contained in gases from most geological sources is very limited.

Rn-220 has a half-life of 54.7 seconds and belongs to the Th-232 decay series. Rn-222 (radon) has a half-life of 3.825 days and belongs to the collapsing sequence of U-238. It combines with various factors in the geological environment until it reaches the ultimate isotope Pb-206 after a half-life of 4.5 billion years It acts as a radioactive gas.

Ra-226, a parent of Rn-222, has a long half-life of about 1,622 years and is less fluid than uranium in weathering. Because of the long half-life and stability of Ra-226, a significant amount of isotopes of Rn-222, the most important concern, are created.

On the other hand, it is known that when these radon breathe air that is accumulated over the environmental standard value or drink water, radon inhaled into the lung enters the body and causes lung cancer.

According to the US Environmental Protection Agency (EPA), the environmental standard for radon (Rn-222) concentration is 4 pCi / L in the air and 10,000 pCi / L in drinking groundwater. Breathing air or drinking water with more than the environmental standard of radon concentration can be a long-term exposure due to the colorless and odorless nature of radon, and the probability of harming health is very high.

In Korea, radon was started to be managed with 10 pollutants in total through the "Indoor Air Quality Control Act of Multi-use Facilities" which came into effect on May 30, 2004. In June of the same year, And the "8-hour measurement of the two-year cycle" as the main method.

The purpose of radon management is to lower the incidence of lung cancer caused by radiation exposure to radon. Therefore, it is urgent to develop a dust collector capable of collecting radon contained in the air in order to reduce the harm to the radon.

1 is a view showing the principle of dust collection of a general dust collector.

1, the dust collecting apparatus may include a charging unit 10 for ionizing radon particles in the air, and a dust collecting unit 20 for collecting charged radon particles in the charging unit 10.

The charging unit 10 includes a discharge line 11 formed of a thin wire made of tungsten and forming an anode, and a pair of discharge electrodes 11, which are vertically provided at a predetermined height difference from the discharge line 11, And an electrode plate (12).

When a high voltage is applied to the discharge line 11, a current starts to flow due to a high potential difference formed between the discharge line 11 and the discharge counter electrode plate 12, and a corona discharge is caused to generate radon particles .

At this time, a plurality of the discharge lines 11 and the discharge corresponding electrode plates 12 may be arranged side by side at regular intervals.

The dust collecting unit 20 is formed by alternately stacking the high voltage electrode 120 and the low voltage electrode 130 in order to collect the charged radon particles in the charging unit 10.

When a high voltage is applied to the discharge line 11, a current starts to flow due to a high potential difference formed between the discharge line 11 and the discharge counter electrode plate 12, causing a corona discharge, ).

At this time, the positively charged radon particles are trapped in the relatively low voltage electrode 130 on the minus side.

The high-voltage electrode 30 is generally formed of an aluminum plate, and the low-voltage electrode 40 may be formed by coating a polyethylene film on an aluminum plate.

The dust collecting unit 20 has a disadvantage in that it can not rapidly flow a large amount of air. Particularly, when the amount of air is high, the dust collecting unit 20 is difficult to collect.

Next, a dust collecting apparatus according to the present invention, which has improved dust collecting efficiency than the dust collecting unit 20 of FIG. 1, will be described with reference to the following drawings. Since the principle of the charging section 10 is basically also applied to the embodiment of the present invention, only the dust collecting section of the present invention will be described below.

2A is a schematic view showing a dust collecting unit 200 of a dust collecting apparatus according to an embodiment of the present invention, and FIG. 2B is a sectional view taken along line i-i of FIG.

The dust collecting unit 200 of the dust collecting apparatus according to the present invention may include a high voltage electrode 220 to which a (+) electrode is applied and a low voltage electrode 230 to be grounded corresponding to the high voltage electrode 220.

More specifically, a tubular housing 210 including an air inlet 210a and an outlet 210b;

A plurality of high voltage electrodes 220 arranged in a row in the longitudinal direction inside the housing 210; And

A plurality of low voltage electrodes (230) arranged in a row in the longitudinal direction inside the housing (210) opposite to the high voltage electrode (220); / RTI >

The high voltage electrode 220 and the low voltage electrode 230 may be formed in a plate shape protruding from the inner side surface of the housing 210 so as to be alternately and vertically spaced from the longitudinal direction of the housing.

A positive voltage is applied to the high voltage electrode 220 to form a high voltage electrode and a relatively low voltage is formed in the low voltage electrode 230 which is grounded corresponding to the high voltage electrode 220, . Accordingly, attracting force and repulsive force are applied to both the electrodes 220 and 230 according to the amount of charge of the radon particles passing through the housing 210 provided with the electrodes 220 and 230, thereby collecting the radon particles inside the housing.

For example, as shown in FIG. 1, when the radon particles positively charged through the charging step before the dust collecting process reaches the dust collecting part 200, the high voltage (+ The repulsive force acts on the electrode 220 and attracts the radon particles to the low voltage electrode 230 because the attraction force acts on the low voltage electrode 230 electrically forming the negative polarity.

Meanwhile, the housing inlet 210a or the outlet 210b may be provided with a blower 250 to guide the outside air to the inlet 210a to purge the air inside the housing and discharge the air to the outlet 210b .

The housing 210 has a cross-sectional area wider toward the discharge port 210b. At this time, as the cross-sectional area of the housing 210 becomes wider, the sizes of the high-voltage electrode 220 and the low-voltage electrode 230 are also proportionally increased.

When the size of the high-voltage electrode 220 and the low-voltage electrode 230 is constant, the interval between the high-voltage electrode 220 and the low-voltage electrode 230 increases as the sectional area of the housing 210 increases toward the discharge port 210b. This is because the ratio of the radon particles that escape to the discharge port 210b without being collected may be increased because it is widened.

Accordingly, the size of the high voltage electrode 220 and the low voltage electrode 230 may be uniformly increased so that the gap between the high voltage electrode 220 and the low voltage electrode 230 may be increased So that the dust removing unit 200 can be improved in radon removing capability.

That is, since a narrow channel is formed on the inlet 210a side of the housing into which the high concentration radon flows, a large amount of radon particles can be easily collected. Further, as the housing conduit is widened toward the discharge port 210b, the transfer speed of the remaining radon particles is reduced as well as the size of the electrode is increased. Accordingly, since the separation distance between the electrodes is kept narrow, .

In the embodiment of the present invention, the electrodes of the dust collecting apparatus are arranged such that the high-voltage electrode 220 and the low-voltage electrode 230, which are dust collecting electrodes, are disposed alternately and spaced apart from each other in a basic configuration for collecting charged radon particles in the charging section 10 .

Here, the high-voltage electrode 220 includes a conductive layer coated with an insulating layer, and the low-voltage electrode 230 is configured to have a conductive portion.

In the present invention, the low-voltage electrode 230 is made of carbon fiber.

3 is a diagram illustrating a low-voltage electrode according to an embodiment of the present invention.

The low-voltage electrode 230 includes porous carbon fibers 231 in the form of a plate-like mesh; And brush-shaped bristles 232 formed on the outer surface of the carbon fiber.

Radon is a gaseous state and contains electrons in its orbit. It is chemically neutral and corresponds to an inert gas. The electron affinity is close to zero and has a higher ionization potential than other elements. Therefore, these elements can not lose or acquire electrons in a steady state, and are difficult to achieve various combinations.

Accordingly, in the present invention, as shown in FIG. 1, a neutral radon gas can be extracted by discharging one electron to a neutral radon gas, and the (+) ion radon particles can be collected on the low voltage electrode.

At this time, in the present invention, the low-voltage electrode 230 is made of carbon fiber, so that the radon gas can be more effectively collected on the low-voltage electrode.

That is, when a low voltage electrode is constructed of a common metal, the radon is collected only on the surface of the electrode, but since the carbon fiber also includes a certain space therein, it can not only capture radon on the surface of the carbon fiber, Radon can also be trapped inside.

Also, depending on the thickness of the carbon fibers, different resistance values are generated depending on the voltage drop, and thus, the difference in electric field can induce acceleration of radon in the capture of radon.

For example, the radon particles reaching the brush portion 232 of the carbon fiber surface may be facilitated to pass through the interior of the porous carbon fiber 231 by acceleration, and thus, by this acceleration, It is possible to collect a large amount of radon particles.

That is, the resistance value of the porous carbon fiber varies depending on the voltage drop from the surface brush portion to the inner surface of the carbon fiber. As a result, the carbon fiber acts as multiple grids, and the radon ions are gradually accelerated , For example, more rapid trapping can occur to the inside of the carbon fiber.

An end of the inlet 210a of the housing 200 and an end of the outlet 210b are connected to an empty space area where the high voltage electrode 220, the low voltage electrode 230, a, b).

This is to prevent a safety accident such as an electric shock which may occur when an electrode or an electromagnet is provided in the inlet and outlet end regions when a voltage is applied.

In the embodiment of the present invention, the electromagnet 240 further includes a plurality of electromagnets 240 aligned in the longitudinal direction inside the housing 210 in proximity to the high voltage electrode 220 and the low voltage electrode 230 .

At this time, the electromagnet 240 may be replaced with a magnet, and a pair of N poles and S poles may face each other, and a plurality of electromagnets 240 may be arranged in the housing 210 in the longitudinal direction.

In addition, the electromagnet 240 may further include a coated photocatalyst. The photocatalyst adsorbed on the electromagnet 240 may be made of TiO 2 .

When the ultraviolet ray is irradiated with TiO 2 , the photoelectric effect is generated. In this case, the present invention may further include an ultraviolet ray irradiating device for irradiating the magnet or the electromagnet 240 with ultraviolet rays.

The ultraviolet irradiator may be located in a predetermined area inside the housing 210.

In addition, since the electromagnet 240 coated with the photocatalyst has a feature of adsorbing and oxidizing and decomposing organic substances contained in the outside air, it can exhibit an atmospheric purification effect such as deodorization and antibacterial activity.

In addition, since the oxidizing power of the photocatalyst not only decomposes organic matters but also removes NOx and SOx and oxidizes heavy metals and excellently oxidizes and decomposes by supplying electricity, the lifetime of the dust collecting apparatus can be permanently improved There is an effect.

Meanwhile, one set of the high voltage electrode 220 and the low voltage electrode 230, which are arranged alternately and spaced apart from each other, are provided between the pair of electromagnets 240.

At this time, a back-pressure circuit 300 is connected to the plurality of low-voltage electrodes 230, and a voltage applied to the low-voltage electrode 230 by the back-pressure circuit 300 increases toward the outlet 210b of the housing , Enabling precise and efficient dust collection.

1, a conventional dust collecting unit 20 not including an electromagnet is formed by alternately laminating a flat-type high-voltage electrode 120 and a low-voltage electrode 130 so that positively charged radon particles are separated from the low- And adsorbed to the electrode 130.

Since the efficiency of the dust collecting unit 20 formed by stacking the electrodes 120 and 130 of the flat plate type is high only at the edges of the high voltage electrode 120 and the low voltage electrode 130, And the magnetic field is reduced toward the central portion of the plate-type electrode, so that the dust collecting efficiency is lowered.

Furthermore, since the radon particles gradually accumulate because the adsorption is good only at the inlet where the air is introduced, while the adsorption is not performed even if a high magnetic field is formed at the outlet edge, the field is blocked by the accumulated radon particles at the inlet side over time So that the dust collecting efficiency is lowered. Therefore, the low voltage electrode 130 needs to be frequently cleaned.

However, in the dust collector 200 of the present invention, the conventional problem of the electromagnet 240 is solved. The dust collecting principle of the dust collector 200 including the electromagnet 240 will be described below.

First, the high voltage electrode 220 and the low voltage electrode 230 having the potential difference by applying the voltage to the dust collecting unit 200 are connected to the low voltage electrode 230 (-) of the high voltage electrode 220, Referring to the coordinate axes shown in FIG. 2A, the direction becomes the x-axis, and the direction of the magnetic field becomes the y-axis perpendicular to the direction of the current.

Subsequently, the positively charged radon particles in the charging section 10 are bent toward the low voltage electrode 230 which is a (-) electrode while being moved to the discharge port through the inlet of the dust collecting section 200, and are adsorbed.

In this case, the electromagnets 240 are continuously arranged in the X-axis direction, which is the longitudinal direction of the housing 210, and the electromagnets 240 The N poles 240a and the S poles 240b of the N pole 240a are opposed to each other. At this time, the N pole and the S pole are disposed perpendicularly to both the electrodes 220 and 230.

The electromagnet 240 is arranged in the N-direction so that the ionized radon particles receive the force of the Lorentz, and both the electrodes 220 and 230 and the electromagnet 240 are vertically operated so that a force acts on the electrode, A magnetic field is formed in the direction from the pole 240a to the S pole 240b, that is, the magnetic field in the y direction is increased.

Therefore, the direction of the magnetic field B passing through the entire surface of the high voltage electrode 220 and the low voltage electrode 220 and the radon (F) generated in the z-axis direction perpendicular to the direction of the current I move The particles are pushed in the z-axis direction. Accordingly, the radon particles can be efficiently collected into the negative electrode (-) electrode 230 arranged in a row in the housing in the z-axis direction.

4 is a schematic view showing a dust collecting part of a dust collecting apparatus according to another embodiment of the present invention.

The dust collecting part 200 'according to another embodiment of the present invention according to FIG. 4 is different from the embodiment shown in FIG. 2 in that the tubular housing 210' has a spirally curved shape, The height of the inlet port 210a 'and the outlet port 210b' is characterized by including a step difference h.

This is because when the housing 210 'is formed into a spiral shape, a current (I) flowing from the inlet 210a' to the outlet 210b 'flows along with a circular magnetic field in the tubular housing Because the direction of the magnetic field has the same counterclockwise (CCW) direction as the spirally curved shape of the housing 210 '.

Thus, the magnetic field formed in the counterclockwise direction can be more efficiently captured in one embodiment of the present invention by trapping radon particles moving through the spiral housing 210 '.

In addition, since the transfer of the radon particles hits the inside of the spiral channel, the radon particles escape at a low speed, so that it is possible to capture more reliable radon particles.

As described above, the dust collecting device according to the present invention includes the dust collecting part for collecting the radon particles equipped with the electromagnet or the magnet, thereby improving the dust collecting efficiency.

The radon particles are a major cause of lung cancer. In the present invention, the collection rate of radon particles in the air can be reduced through the dust collecting apparatus of the present invention to reduce the incidence of lung cancer caused by exposure to radon radiation.

While the present invention has been described in connection with what is presently considered to be practical exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood. It is therefore to be understood that the above-described embodiments are illustrative in all aspects and not restrictive.
