Description

SCRUBBER FOR PURIFIING EXHAUST GAS OF SHIP

The present invention relates to a scrubber for purification of exhaust gas of a ship, and more particularly to a scrubber for purification of exhaust gas of a ship which purifies the exhaust gas of a marine engine.

Regulation of sulfur oxides emissions from ship engines has been strengthened in the Emission Control Area (ECA) since 2015 and will be strengthened to 0.5% in all regions since 2020.

Techniques for removing sulfur oxides include the use of low-sulfur fuels or the use of gaseous fuels that do not contain sulfur, but low-sulfur fuels are much more expensive than heavy fuel oil, and gaseous fuel technology There are difficulties because the cost of remodeling is too high and it is possible for a ship to be newly constructed, but its application is limited due to many problems such as infrastructure.

Therefore, a post-exhaust treatment technique for reducing sulfur oxides discharged into the exhaust gas is being developed as a practical alternative.

Since sulfur oxides easily dissolve in water, a scrubber system that removes sulfur oxides by spraying water has become a typical technique. This technology is largely classified into a wet scrubber and a dry scrubber.

Dry scrubbers, which are widely used on land, are very large in size and are generally excluded from ship application, and wet scrubber technology is being applied.

Wet scrubber technology applied to ships improves the performance by filling the packing and spraying water to remove pollutants and disturb the flow path to increase the contact time, It is required to have a very large space, weight and cost.

Accordingly, by forming bubbles when the exhaust gas flows into the washing water and forming strong turbulence in the washing water, contaminants in the exhaust gas can be effectively removed as the mixing with the washing water is actively performed.

Specifically, the main body 100 includes a first housing 110 having a gas inflow portion 111 formed at an upper portion thereof and a second housing 120 having a gas outflow portion 121 formed at an upper portion thereof. One of the housing 110 and the second housing 120 may be spaced apart from the other and the bubble forming member 200 may be installed at the lower end thereof.

The exhaust gas flowing through the gas inlet 111 of the first housing 110 flows downward from the inside of the first housing 110 and then flows into the second housing 120 from the lower side, The second housing 120 flows upward through the bubble forming member 200 and passes through the receiving portion 101 containing the washing water as bubbles and then flows upward in the second housing 120, (121).

1 to 4, the second housing 120 is disposed in the first housing 110 and is pushed by the inflow pressure of the exhaust gas so that the receiving portion 101 The bubble forming member 200 may have a structure that forms a bottom portion of the second housing 120 when the bubble forming member 200 is positioned at a lower portion of the second housing 120. For reference, the second housing 120 may extend upwardly through the upper portion of the first housing 110 as shown in the figure.

[

The process of removing contaminants of the exhaust gas from the washing water through the above-described structure will be described below.

First, when the exhaust gas starts to flow through the gas inlet 111, the washing water starts to be supplied through the washing water supply line S to remove contaminants of the exhaust gas. The accommodating portion 101 to be accommodated is located at the lower portion in the second housing 120 by the pressure of the exhaust gas. For example, in order to adjust the position of the accommodating portion 101, an inflow amount of the exhaust gas and a flow rate of the exhaust gas may be adjusted. The flow rate of the exhaust gas and the speed of the exhaust gas can be controlled through various design structures such as the cross sectional area of the gas inlet 111.

The bubble forming member 200 may be formed in a bottom portion of the second housing 120 so that the exhaust gas may pass through the receiving portion 101 positioned below the second housing 120 as bubbles, The exhaust gas passes through the bubble forming member 200 having a plurality of through holes 200a immediately before or immediately after the introduction of the exhaust gas into the accommodating portion 101, As shown in Fig.

In addition, contaminated cleaning water is discharged through the cleaning water discharge line (D) at the lower end of the second housing 120 while removing contaminants from the exhaust gas. Further, such rinse water can be purified and used again through the cleaning and conditioning system R connected to the rinse water discharge line D and the rinse water supply line S, respectively.

5 to 8, the first housing 110 is disposed in the second housing 120, and the receiving portion 101 is pushed by the inflow pressure of the exhaust gas. The lower end of the first housing 110 defines an enlarged portion 112 having an enlarged space around the lower portion of the second housing 120. The lower portion of the first housing 110 forms an enlarged portion 112, As shown in Fig.

At this time, a washing water supply line S for supplying washing water to the receiving portion 101 is connected to the main body 100, and a washing water discharge line (not shown) for discharging the washing water is connected to the lower end of the second housing 120 D) can be connected.

More specifically, the washing water supply line S is connected to the first injection nozzle N1 and the second injection nozzle N2, respectively, which will be described later in the main body 100, and the first injection nozzle N1 and the second The washing water is sprayed through the spray nozzle N2 and the washing water can be supplied to the receiving portion 101. [

The process of removing contaminants of the exhaust gas from the washing water through the above-described structure will be described below.

First, when the exhaust gas starts to flow through the gas inlet 111, the washing water starts to be supplied through the washing water supply line S to remove contaminants of the exhaust gas. The accommodating portion 101 to be accommodated is located at the lower portion in the second housing 120 by the pressure of the exhaust gas. For example, in order to adjust the position of the accommodating portion 101, an inflow amount of the exhaust gas and a flow rate of the exhaust gas may be adjusted. The flow rate of the exhaust gas and the speed of the exhaust gas can be controlled through various design structures such as the cross sectional area of the gas inlet 111.

The bubble forming member 200 may be inserted into the extension portion 112 of the first housing 110 so that the exhaust gas may be passed through the accommodating portion 101 located in the lower portion of the second housing 120 as bubbles, So that the exhaust gas passes through the bubble forming member 200 having a plurality of through holes 200a immediately before or immediately after the introduction of the exhaust gas into the receiving portion 101, As shown in Fig.

In addition, contaminated cleaning water is discharged through the cleaning water discharge line (D) at the lower end of the second housing 120 while removing contaminants from the exhaust gas. Further, such rinse water can be purified and used again through the cleaning and conditioning system R connected to the rinse water discharge line D and the rinse water supply line S, respectively.

At least one or more first injection nozzles N1 are formed in the first housing 110 so that the washing water injected through the first injection nozzle N1 is discharged through the gas inlet portion 111, And can be mixed with the exhaust gas.

The exhaust gas flowing through the gas inlet 111 of the first housing 110 flows into the first housing 110 through the gas inlet 111, The washing water is evaporated by heat exchange with washing water sprayed from the first spray nozzle N1.

The cleaning water that has been evaporated and thus atomized is water vapor, which is actively mixed with the exhaust gas. Thus, the exhaust gas is washed out and finally condensed to be combined with the washing water contained in the receiving portion 101, The substance can be effectively removed.

As shown in FIG. 2, the first injection nozzle N1 may have a structure in which a plurality of first injection nozzles N1 are disposed in the upper portion of the first housing 110, as shown in FIG. 2. In another embodiment, As shown in FIG. 1, a plurality of the exhaust gas may be arranged in the first housing 110 downwardly along the central portion of the first housing 110, so that mixing with the exhaust gas can be performed more effectively.

For reference, the first injection nozzle N1 can be easily evaporated by the high temperature of the exhaust gas by reducing the cleaning water injection flow rate to be smaller than the second injection nozzle N2 described later. The main pipe M provided with the first injection nozzle N1 of FIG. 6 may be configured to extend to the outside so as to be connected to an external supply pipe, although not shown in the drawing.

Further, the gas inlet 111 may be inclined to the side of the first housing 110 such that the exhaust gas is pivoted inside the first housing 110.

As the exhaust gas flows into the first housing 110 and is circulated in this way, the flow route in the first housing 110 is made uniform to minimize the dead space, thereby increasing the mixing rate with the evaporated and cleaned cleaning Accordingly, contaminants of the exhaust gas can be effectively removed.

In addition, at least one second injection nozzle N2 is formed on the upper portion of the second housing 120, and a porous packing P (P) is formed on the lower side of the second injection nozzle N2 in the second housing 120, May be disposed.

Here, the porous packing P may be formed by filling a plurality of porous ceramic balls as an example.

The porous packing P flows down through a large number of holes injected by the upper second injection nozzle N2 so that the exhaust gas passes through the porous packing P and contaminants are washed away in the washing water The pollutants of the exhaust gas can be effectively removed according to the load.

Further, the first housing 110 and the second housing 120 are formed into a double pipe structure by respectively having a tubular shape as shown in the figure, so that the exhaust gas flowing through the gas inlet 111 flows downward It is possible to increase the removal efficiency of the pollutants of the exhaust gas even in a ship in which the installation space is relatively smaller than the land level by maximizing the flow length of the exhaust gas within a certain space.

As a result, according to the present invention, the bubble forming member 200 in the washing water of the receiving portion 101, the evaporation and mixing region in which the washing water is sprayed and mixed with the exhaust gas by evaporating the washing water into heat of the exhaust gas before passing through the received washing water, A water mixing region in which the exhaust gas is passed in the form of bubbles and mixed with the washing water and a packing mixing region where the exhaust gas is mixed with the washing water while passing through the porous packing P are constituted, The pollutants of the exhaust gas can be effectively removed even at a low cost.
