Description

[0001] Apparatus for reducing pollutant [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust gas pollutant abatement apparatus, and more particularly, to an exhaust gas pollutant abatement apparatus having a structure capable of effectively purifying pollutants contained in exhaust gas and discharging the pollutants.

Generally, various engines installed on a ship generate power by burning fossil fuels. At this time, the exhaust gas generated in the combustion process of the fuel includes harmful substances such as SOx, NOx, and PM, It can cause pollution. For these reasons, environmental regulations for air pollution of vessels are being strengthened, and various processing devices are being applied to ships in order to satisfy various regulations.

In the environmental regulations on air pollution, regulations that specify the sulfur content in the exhaust gas emitted from the engine when operating and docking the marine emission control area (ECA) are less than 0.1% As a method for removing the cargo, it is possible to use an ultra low sulfur fuel having a sulfur content of 0.1% or less or a wet scrubber. However, since the super low sulfur oil is very expensive and the system such as the production equipment is insufficient, a wet scrubber is usually used.

A wet scrubber removes sulfur oxides by vapor-liquid contact with seawater, fresh water or alkaline solution and exhaust gas. Oxidation of sulfur oxides and nitrogen oxides before gas-liquid contact can reduce sulfur oxides and nitrogen oxides at the same time. Accordingly, it is possible to improve the efficiency of oxidation of sulfur oxides and nitrogen oxides contained in the exhaust gas, improve the contact efficiency between seawater, fresh water, or an alkaline solution and exhaust gas to effectively remove contaminants contained in the exhaust gas A reduction apparatus of the present invention has become necessary.

Korean Patent Publication No. 10-2005-0003335 2005. 01. 10

An object of the present invention is to provide an exhaust gas pollutant abatement apparatus having a structure capable of effectively purifying and discharging contaminants contained in exhaust gas.

The technical objects of the present invention are not limited to the technical matters mentioned above, and other technical subjects not mentioned can be clearly understood by those skilled in the art from the following description.

According to an aspect of the present invention, there is provided an exhaust gas pollutant reduction apparatus comprising: a flow line through which exhaust gas flows; a radical generator that generates radicals and supplies the flow to the flow line; A scrubber for spraying clean water on the reactant material of the exhaust gas and the radical supplied through the scrubber to remove contaminants, and a magnetized water generator for supplying magnetized water to at least one of the radical generator and the scrubber.

The magnetized water generating unit may be installed in a water supply line for introducing moisture into the radical generating unit.

The magnetized water generating unit may be installed in the radical generating unit to convert moisture into magnetized water in the radical generating unit.

The magnetized water generating unit may be installed in a nozzle for spraying washing water into the scrubber.

The magnetized water generating unit may be installed in the scrubber to convert the washing water sprayed into the scrubber into magnetized water.

The exhaust gas pollutant abatement apparatus may further include a storage tank for storing the washing water that has passed through the scrubber, and a magnetic holding unit installed in the storage tank to maintain the magnetism of the washing water stored in the storage tank.

The magnetism generating portion or the magnetic holding portion may include a permanent magnet or an electromagnet.

The exhaust gas pollutant abatement apparatus may further include a heat exchange unit for exchanging heat between the radical generating unit and the flow line to raise the temperature of the radical generating unit with the heat of the exhaust gas.

According to the present invention, since a magnetized water having a high solubility in the production of radicals for oxidizing sulfur oxides and nitrogen oxides contained in the exhaust gas is used, radicals can be effectively generated even in a small amount. In addition, by generating radicals using the activated magnetized water, the binding force with the O radical can be improved to promote the OH radical generating reaction, thereby improving the oxidation efficiency of sulfur oxides and nitrogen oxides.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. To fully disclose the scope of the invention to those skilled in the art, and the invention is only defined by the scope of the claims. Like reference numerals refer to like elements throughout the specification.

Hereinafter, the exhaust gas pollutant abatement apparatus according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 3. FIG.

The apparatus for reducing exhaust gas pollutants according to an embodiment of the present invention is an apparatus for exhausting air suited to exhaust standards by reducing the concentration of various pollutants (nitrogen oxides, sulfur oxides, dust, etc.) contained in exhaust gases, So that pollutants of the exhaust gas generated in the ship can be removed. However, the exhaust gas pollutant abatement device is not limited to being mounted on a ship, and can be applied to various uses where pollutant removal of exhaust gas is required.

Since the exhaust gas pollutant abatement apparatus uses magnetized water having high solubility in the production of radicals for oxidizing sulfur oxides and nitrogen oxides contained in the exhaust gas, radicals can be effectively generated even in a small amount. In addition, by generating radicals using the activated magnetized water, the binding force with the O radical can be improved to promote the OH radical generating reaction, thereby improving the oxidation efficiency of sulfur oxides and nitrogen oxides. Further, by injecting magnetized water having a high solubility with scrubber and using it as cleaning water, it is possible to effectively remove contaminants contained in the exhaust gas even in a small amount. Further, since the magnetized water has a high sterilizing power, a separate treatment process for killing the microorganisms in the washing water can be omitted.

Hereinafter, the exhaust gas pollutant reduction apparatus will be described in detail with reference to Figs. 1 to 3. Fig.

FIG. 1 is a block diagram schematically showing an exhaust gas pollutant reduction apparatus according to an embodiment of the present invention. FIG. 2 is a view for explaining a process of generating magnetized water in the magnetized water generating unit of FIG. 1, Is an operational view for explaining the operation of the exhaust gas pollutant abatement apparatus according to an embodiment of the present invention.

An exhaust gas pollutant reduction apparatus 1 according to the present invention includes a flow line 10, a radical generator 20, a scrubber 30, and a magnetized water generator 40.

The flow line 10 is a hollow tube through which exhaust gas flows, one side connected to a combustion engine (not shown) and the other side connected to a scrubber 30, which will be described later. The flow line 10 is directly connected to the exhaust pipe of the combustion engine and can be a passage through which exhaust gas of high temperature is directly moved or passes through various heat exchangers to recycle most of the exhaust gas heat and the remaining waste gas moves. Here, the combustion engine refers to a device that generates various kinds of power required for a ship by burning fuel, and may be formed of, for example, a main engine, a generator engine, or the like.

Exhaust pipes of a plurality of combustion engines may be connected to the flow line 10, and a plurality of combustion engines may be selectively operated as needed. Such a combustion engine usually generates fossil fuel to generate power, and thus generates exhaust gas resulting from combustion of fossil fuel. That is, the exhaust gas generated in the combustion engine contains a large amount of nitrogen oxides, sulfur oxides, dust, and the like, and is supplied to the scrubber 30 through the flow line 10.

The radical generator 20 generates radicals to oxidize the nitrogen oxides and the sulfur oxides. The radical generator 10 has a connection line 10a connected to the flow line 10 at one side thereof. The generated radicals are connected to the flow line 10 Can supply. At this time, a control valve (not shown) for adjusting the supply of radicals may be provided at the connection portion between the connection line 10a and the flow line 10. [

The radical generator 20 generates radicals by supplying air and moisture irradiated with ultraviolet rays. Radicals are chemical species that have draft electrons that are not paired with the valence electron orbital. They are electrically neutral but very reactive. Thus, the radicals supplied to the flow line 10 react with the nitrogen oxides and the sulfur oxides contained in the exhaust gas, thereby oxidizing the nitrogen oxides and the sulfur oxides to a state of high solubility in water. The reaction formula in which nitrogen oxides and sulfur oxides are oxidized by reacting with radicals is as follows.

<Reaction Scheme>

NO + O → NO 2

NO + H 2 O → NO 2 + OH

NO + OH → HNO 2

HNO 2 + OH → NO 2 + H 2 O

NO + O 3 ? NO 2 + O 2

NO 2 + OH - &gt; HNO 3

SO 2 + OH - &gt; HSO 3

HSO 3 + OH - &gt; H 2 SO 4

SO 2 + O - &gt; SO 3

SO 3 + H 2 O - &gt; H 2 SO 4

That is, the NO contained in the exhaust gas by a radical such as a hydroxyl group (OH) is oxidized in the form of NO 2, HNO 2, HNO 3, in the form of SO 2 also HSO 3, H 2 SO 4, SO 3 Oxidized. In general, NOx, and is approximately 90% exists as a NO condition, and the other is present in the NO 2. NO is not soluble due to its low solubility in water, but NO 2 , HNO 2 , and HNO 3 , which are oxidized forms of NO, are highly soluble in water and have a property of dissolving in water. That is, when NO is oxidized and supplied to the scrubber 30, the nitrogen oxide contained in the exhaust gas can be easily dissolved in the washing water, thereby effectively removing the nitrogen oxide contained in the exhaust gas. In addition, when SO 2 is oxidized and supplied to the scrubber 30, the sulfur oxides are easily dissolved in the washing water, and the sulfur oxides contained in the exhaust gas can be effectively removed.

The radical generator 20 receives moisture and air through the water supply line 21 and the air supply line 22, respectively, and generates radicals by irradiating ultraviolet rays having a frequency of 200 nm or less to the air. When the radical generating unit 20 irradiates ultraviolet rays to the air, the oxygen molecules (O 2 ) in the air undergo photodecomposition to generate O radicals, and the O radicals form water molecules (H 2 O ) To produce OH radicals as active species. The reaction scheme in which the OH radical is produced is as follows.

<Reaction Scheme>

O 2 + UV → 2O

O (1D) + H 2 O → 2OH

On the other hand, the scrubber 30 is an apparatus for spraying cleaning water on the reactant material of the exhaust gas and the radical to cause gas-liquid contact, and may be a conventional wet scrubber. The scrubber 30 is connected to the flow line 10 at one side and is connected to the exhaust gas and radical reactants such as oxidized nitrogen oxides (NO 2 , HNO 2 , HNO 3, etc.) or oxidized sulfur oxides (HSO 3 , H 2 SO 4 , SO 3, and the like), and the cleaning water supplied from the cleaning water supply line 31 is sprayed to the oxidized nitrogen oxide or sulfur oxide to remove contaminants.

As the exhaust gas and washing water come into contact with the inside of the scrubber 30, contaminants such as nitrogen oxides, sulfur oxides, and dusts contained in the exhaust gas can be removed, and contaminants such as nitrogen oxides, sulfur oxides, The removed exhaust gas may be discharged to the outside through a separate discharge pipe (not shown). Since the exhaust gas discharged through the discharge pipe is in a state in which contaminants such as nitrogen oxides, sulfur oxides, and dust have been removed, it can be discharged into the atmosphere in compliance with the exhaust standards.

Further, the magnetized water may be supplied to at least one of the radical generator 20 and the scrubber 30. In other words, the radical generator 20 can generate radicals by receiving magnetized water, and the scrubber 30 can receive the magnetized water and remove contaminants contained in the exhaust gas. Magnetized water is a water with a hexagonal arrangement of water molecules due to its strong magnetic field. It is characterized by high solubility and sterilizing power by ion activation. By supplying such magnetized water to the radical generator 20, radicals can be effectively generated even in a small amount, and the binding force with the above-mentioned O radical can be improved, so that the OH radical generating reaction can be promoted. As the OH radical generating reaction is promoted, the oxidation efficiency of sulfur oxides and nitrogen oxides can be improved. Further, since the magnetized water is supplied to the scrubber 30, the contaminants contained in the exhaust gas can be effectively removed even in a small amount, and a separate process for killing the microorganisms in the washing water is omitted, Can be saved.

The magnetized water is generated from the magnetized water generating section 40 and supplied to the radical generating section 20 or the scrubber 30. The magnetized water generating section 40 is connected to the water supply line 21, the radical generating section 20, The line 31, and the scrubber 30, as shown in FIG. Hereinafter, the structure in which the magnetized water generating section 40 is provided in the water supply line 21 will be described more specifically.

The magnetized water generating portion 40 may include a permanent magnet or an electromagnet and may be installed on a water supply line 21 for introducing water into the radical generating portion 20 as shown in FIG.

The magnetized water generating section 40 is provided on the water supply line 21 so that water can be converted into magnetized water and supplied to the radical generating section 20.

The magnetized water generating portion 40 may be formed of a permanent magnet on a plate as shown in FIG. 2 (a), or may be formed of an electromagnet in the form of a coil, as shown in FIG. 2 (b) And may be installed on the outer circumferential surface of the water supply line 21. At this time, the magnetized water generating section 40 can form a magnetic field in a direction perpendicular to the direction in which water flows. The magnetized water generating section 40 is formed only on a part of the outer circumferential surface of the water supply line 21 and the magnetized water generating section 40 is formed on the entire outer circumferential surface of the water supply line 21 It is possible.

In general, a water molecule (H 2 O) exists as a polymer [(H 2 O) n ] in which 13 to 15 molecules are assembled by hydrogen bonding, which is called a cluster. That is, the moisture is supplied to the water supply line 21 with a large cluster value, flows along the water supply line 21, and passes through the magnetized water generating unit 40. As described above, since the magnetic field generating portion 40 forms a magnetic field in a direction perpendicular to the direction in which the water flows, when the water passes through the magnetized water generating portion 40, the hydrogen atom at the plus (+ -) polar oxygen atoms are attached to each other to cause motion such as rotation, stretching, and vibration, so that water is converted into microparticles and activated. That is, when the moisture passes through the magnetized water generating unit 40, the number of clusters becomes smaller, and the adjacent clusters form a hexagonal structure. In other words, moisture is converted to magnetic water.

The water converted into magnetized water has a small number of clusters, which increases the solubility. Therefore, it is possible to generate radicals in a small amount, and at the same time, it can activate OH radicals because it is in an activated state.

Hereinafter, the exhaust gas pollutant abatement apparatus 1a according to another embodiment of the present invention will be described in detail with reference to FIG.

4 is an operation diagram for explaining the operation of the exhaust gas pollutant abatement apparatus according to another embodiment of the present invention.

[ Accordingly, the description of the remaining components will be replaced by the foregoing description, unless otherwise noted.

The magnetized water generating unit 40 is installed in the radical generating unit 20 and can convert moisture into magnetized water in the radical generating unit 20. [ That is, the magnetized water generating unit 40 may convert water into magnetized water and supply it to the radical generating unit 20, or may convert the water supplied to the radical generating unit 20 into magnetized water.

The magnetized water has a feature that the arrangement of water molecules is changed into a hexagonal structure by a magnetic field, and it is reduced to a circular state after a certain time passes. Since the magnetized water generating portion 40 is provided in the radical generating portion 20, moisture can be continuously maintained in the state of being converted into the magnetized water, so that the OH radical generating reaction can be promoted regardless of the passage of time.

Accordingly, the description of the remaining components will be replaced by the foregoing description, unless otherwise noted.

The magnetized water generating unit 40 is installed in the nozzle 32 for spraying the washing water into the scrubber 30, so that the washing water can be converted into magnetized water.

The cleaning water supply line 31 is branched into a plurality of nozzles in the scrubber 30, and the nozzles 32 are connected to the respective ends of the cleaning water supply line 31, so that the cleaning water converted into the magnetized water can be sprayed in the form of fine particles. Since the magnetic water is sprayed in the form of fine particles, the contact efficiency with the exhaust gas is increased, and the pollutant can be effectively removed.

The magnetized water generating section 40 is provided in front of the branching portion of the washing water supply line 31. However, the magnetized water generating section 40 is not limited to the magnetized water generating section 40, Or may be provided on the branched cleansing water supply line 31, respectively, or may be installed in the nozzles 32, respectively. When the magnetized water generating portion 40 is provided on each branched cleaning water supply line 31 or installed in the nozzle 32 respectively, the diameter of the tube may be narrow and the intensity of the magnetic field may increase, Can be performed more quickly.

[ The exhaust gas pollutant abatement device 1d according to another embodiment of the present invention is substantially the same as the above embodiment except that the exhaust gas pollutant abatement device 1d further includes the storage tank 50 and the magnetic holding portion 60. [ Accordingly, the description of the remaining components will be replaced by the foregoing description, unless otherwise noted.
