Apparatus and method for inhibiting attachment of marine organisms to a power plant intake port using carbon dioxide captured from a power plant stack

The present invention relates to an apparatus and a method for restraining attachment of a marine life to a power plant intake port using carbon dioxide captured from a power plant stack, and more particularly, to an apparatus and method for suppressing marine life adherence using carbon dioxide captured from a power plant stack, And an apparatus and a method for inhibiting attachment of marine organisms that lower the pH of seawater.

The performance of a heat exchanger in an electricity generating plant is an effective means for reducing fuel and carbon dioxide gas (CO ₂ ) emissions. Conventionally, seawater is frequently used as cooling water. However, since marine life (barn, flow, etc.) attaches to the outside of piping of the heat exchanger and performance deteriorates, measures against pollution and adhesion of marine life are needed.

Chlorine treatment, which has been used as long ago as painting and painting, has a power plant that can not be applied in some areas. In addition, even if chlorine treatment is applied to prevent marine organisms from adhering to the heat exchanger, if too much residual chlorine is available, even beneficial marine organisms can be killed. If too little residual chlorine is added, marine organisms are adhered to the cooling water cooler It is very difficult to control the concentration of residual chlorine, so that the damage caused by the attached organisms can not be completely prevented.

On the other hand, greenhouse effect, which is the main cause of global warming, is known to be the main cause of carbon dioxide, water vapor, methane, freon gas and ozone. Among them, fossil fuels such as coal, Carbon dioxide.

This is why carbon capture and storage (CCS) technology, which is a technology to store carbon stocks at a high concentration before the release of a large amount of CO ₂ into the atmosphere, and stores it, is attracting worldwide attention .

Japanese Patent Publication No. 5295819, which is a conventional technique for suppressing slime that forms a film on the surface of a facility and attachment of living things in the seawater, which is the main damage target of such a power plant, and solves the problem of carbon dioxide which becomes increasingly problematic, (Carbon dioxide gas / sea water) of 0.1 to 4/100 with the seawater is injected into the decompressed seawater to introduce carbon dioxide gas having a diameter of 10 to several tens of m A method and an apparatus for preventing marine organisms from adhering to marine organisms within the pH range while generating micro bubbles and dissolving carbon dioxide gas in seawater to adjust the pH of seawater to within a range of 6.4 to 8.1. . According to the above-mentioned literature, carbon dioxide, which is an exhaust gas, can be effectively utilized, and carbon dioxide injected can be adjusted to a pH range effective for preventing the attachment of marine organisms, thereby preventing the attachment of marine organisms .

However, in the above-mentioned prior art, since the microbubble generator for introducing and depressurizing the seawater taken from the seawater channel into the mixing portion and supplying the carbon dioxide introduced from the gas channel to the decompressed seawater is used, the entire amount of the introduced carbon dioxide is hardly dissolved , And the apparatus for microbubbing a large amount of gas is also large.

Therefore, in order to adjust the pH of the seawater to an appropriate range, it is necessary to inject an excessive amount of carbon dioxide, and the dissolved carbon dioxide is released into the atmosphere, which may cause another problem.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an apparatus and a method for suppressing the attachment of marine organisms to the intake port of a power plant using carbon dioxide captured from the power plant stack of the present invention will be described in detail with reference to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram of an apparatus for suppressing the attachment of a marine life to a power plant intake port using carbon dioxide collected from a power plant stack according to an embodiment of the present invention. FIG.

1, the apparatus for inhibiting attachment of marine life according to an embodiment of the present invention includes a carbon dioxide collector 20, a bubble trap 40, a suction pump 50, a carbon dioxide dissolution tank 60, a circulating water pump 70, And a micro bubble generator (80).

The carbon dioxide collector 20 is a device for collecting carbon dioxide generated from the power plant stack 10. The carbon dioxide collecting device or the collecting method is not particularly limited and a known apparatus or method can be used.

The bubble trap 40 is a device for dissolving the carbon dioxide captured from the carbon dioxide collector 20 in the cooling seawater of the heat exchanger so that the marine life is not adhered to the power plant heat exchanger.

2 to 4, the bubble trap 40 can be roughly classified into a carbon dioxide generating unit 41 and an unreacted carbon dioxide collecting unit 43.

The carbon dioxide gasifier 41 is a device for discharging the carbon dioxide collected from the carbon dioxide sorter 20 in the seawater. The carbon dioxide gasifier 41 separates the carbon dioxide captured from the carbon dioxide sorter 20 A feeding pipe for feeding is connected to the connection port 412 and is installed standing up in the seawater.

The carbon dioxide generating unit 41 includes a main accumulator 411 coupled to the connector 412, a first supporting tube 416, a first primary collector 419, a second supporting tube 420, The second support body 420 and the second support body 420 are provided on the upper side of the second base body 423 in consideration of the depth of the water to be treated and the dissolution rate of carbon dioxide, The organ 422 can be stacked with a plurality of air bag assemblies that are the same as the first air bag collection 419 and the second air bag collection 4230.

The operation principle of the carbon dioxide gas dissolving apparatus of the present invention having the above-described structure is as follows. Carbon dioxide introduced through the connecting port 412 is raised to the side of the main air diffusing pipe 411, Not only the carbon dioxide can be dissolved smoothly but also the stirring action with seawater can be performed smoothly.

Particularly, in the gas confinement space 413 formed in the main air diffusing pipe 411, compression and expansion of carbon dioxide occurs and vibration can be generated. Therefore, even if a separate vibration means is not provided, So that the dissolution efficiency and rate of carbon dioxide can be increased.

The carbon dioxide emitted from the main air diffusing pipe 411 is collected in the first air bag collection unit 419 and then conveyed upward through the first outlet 418 and supported by the second support member 421 The auxiliary engine 422 is closed at its upper surface to perform a function similar to that of the main air diffuser 411.

The second air bag assembly 423 covers the upper part of the auxiliary air intake assembly 422 and collects the gas emitted from the auxiliary air intake assembly 422. The collected air is supplied to the upper side of the second air bag assembly 423 And is discharged to the upper portion through the second outlet 424 formed at the center portion.

3 is a conceptual view showing an embodiment of an unreacted carbon dioxide collecting device constituting a bubble trap. Unreacted carbon dioxide collecting device 43 includes collecting device supporting portions 431 and 432, And a collecting device ceiling portion 434 having a plurality of connected carbon dioxide generating devices 41, a diffuser fixing portion 433 and an unreacted carbon dioxide exhausting pipe 435.

The collecting device 43 has a predetermined shape having a space portion capable of accommodating the carbon dioxide gas generating device 41. It is preferable that the collecting device body 43 has a lower surface and a side surface, and the upper surface, that is, the ceiling portion 434, is closed. It is more preferable that the ceiling portion 434 is closed except for the unreacted carbon dioxide discharge pipe 435. The ceiling portion 434 has an upwardly downward bulging structure in which the cross- It is most preferable to provide the carbon dioxide exhaust pipe 435 near the vertex of the upper surface having the smallest cross-sectional area.

By forming the upper surface with the above-described structure, unreacted carbon dioxide can be collected in a container, and it is also very easy to supply the unreacted carbon dioxide to a carbon dioxide dissolution tank 60 to be described later.

In addition, at a predetermined position of the inner space of the plurality of collecting device supports 431 and 432 for fixing and supporting the unreacted carbon dioxide collecting device 43 to the bottom of the seawater, the carbon dioxide generating device 41 is separated from the bottom of the seawater by a predetermined distance And a fixing unit 433 for fixing the carbon dioxide gas. The carbon dioxide gasifier unit 433 is preferably configured to communicate with the connection port 412 of the carbon dioxide gasifier 41 so that the carbon dioxide transferred from the carbon dioxide sorter 20 can be supplied.

Due to the above structure, the seawater in which the carbon dioxide is dissolved can freely flow through the space between the side and bottom spaces between the plurality of collecting device supporting portions 431 and 432, and is discharged through the second outlet 424 of the air diffuser 41 The unreacted carbon dioxide discharged is collected in a collecting device ceiling portion 434 located at the upper portion of the air diffuser 41. The unreacted carbon dioxide is sucked by the suction pump 50 communicated with the unreacted carbon dioxide discharge pipe 435 And is transferred to the carbon dioxide dissolution tank 60. Of course, it is natural that not only unreacted carbon dioxide but also some seawater can be transferred to the carbon dioxide discharge pipe 435.

4 is a conceptual view showing a modified embodiment of the unreacted carbon dioxide collecting apparatus constituting the bubble trap. The carbon dioxide discharge pipe 435 may be provided to interconnect the second outlets 424 of the plurality of carbon dioxide generating units 41 .

That is, unlike the embodiment of FIG. 3, the ceiling portion 435 for collecting unreacted carbon dioxide is not provided, while the unreacted carbon dioxide emitted through the second outlet 424 of the carbon dioxide generating unit 41 The carbon dioxide discharge pipe 435 is connected to the second discharge port 424 so that the carbon dioxide discharge pipe 435 is directly connected to the second discharge port 424 so that the carbon dioxide discharge pipe 435 is connected to the suction pump 50 and is transferred to the carbon dioxide dissolution tank 60.

On the other hand, it is apparent that the arrangement and the number of the carbon dioxide generating units 41 can be freely changed.

Next, the carbon dioxide dissolving tank 60 will be described with reference to Fig.

The carbon dioxide dissolving tank 60 is provided with a tank main body 61, a liquid forming container 62 provided in the tank main body 61, unreacted carbon dioxide and a circulating seawater mixture supply pipe 63 and a discharge pipe 64 have.

The liquid-producing container 62 is provided in the tank main body 61 and has a neck shape. The reason why the liquid-condition generating container 62 is in the shape of a bottle as described above is to make it possible to make the liquid film of the liquid film capable of improving the dissolution efficiency of carbon dioxide.

That is, unreacted carbon dioxide not dissolved in the bubble trap 40 and seawater circulated by the circulating water pump 70 are injected into the vacuo production container 62 inside the tank main body 61 through the supply pipe 63 . The mixture of the injected carbon dioxide and the seawater forms a liquid film in the form of droplets in the upper part of the liquid production container 62, and moves to the lower part over the liquid production container 62 in a very thin film state. Therefore, since the circulating water amount of the seawater maintains the thin film shape as described above, the contact efficiency between the carbon dioxide and the seawater increases and the dissolution rate increases as a result.

Here, circulating seawater in which carbon dioxide is dissolved by liquid film formation is transferred to a micro bubble generator 80 to be described later through a discharge pipe 64 provided at one side of the tank main body 61.

Although the shape and size of the tank body 61 are not particularly limited, it is preferable that the bottom surface and the side surface have smooth curved surfaces so that the carbon dioxide and the circulating water can flow easily. Also, since the seawater is introduced, It is preferable to coat with a strong substance.

Next, the carbon dioxide-containing circulation seawater transferred from the carbon dioxide dissolution tank 60 flows into a micro bubble generator 80 that forms fine bubbles, and the micro bubble generator 80 generates bubbles having a size of several tens of micrometers, .

Here, the type and method of the micro bubble generator 80 are not particularly limited, and a known generator to which an ejection method, an acid generation method, or the like is applied can be used.

Hereinafter, with reference to FIG. 6, a description will be made of a method for restraining attachment of marine life to a power plant intake port using carbon dioxide captured from a power plant stack of the present invention.

The method for attaching marine organisms according to the present invention includes a first step of collecting carbon dioxide generated from a power plant coland 10, a step of supplying the collected carbon dioxide to a bubble trap 40 through a transfer blower 30, The unreacted carbon dioxide not dissolved in the bubble trap 40 and the seawater for circulation are supplied to the carbon dioxide dissolution tank 60 to dissolve the carbon dioxide in the seawater for circulation And a fourth step of supplying microbubble generator 80 with circulating seawater in which unreacted carbon dioxide is dissolved to generate microbubbles.

The method for suppressing the attachment of marine organisms will be described in detail. First, carbon dioxide gas generated by burning fossil fuel is collected from the power plant stack 10. Here, the carbon dioxide can collect carbon dioxide generated from the stack 10 by using a known method or apparatus.

The captured carbon dioxide is then subjected to a step of lowering the pH of the seawater to dissolve the marine organisms in the cooling seawater of the heat exchanger so as not to adhere to the power plant heat exchanger. The collected carbon dioxide is transferred to the bubble trap 40 through the carbon dioxide transfer blower 30 and the transfer pipe 31. The carbon dioxide in the bubble trap 40 dissolves in the seawater.

The bubble trap 40 includes a carbon dioxide generating unit 41 and an unreacted carbon dioxide collecting unit 43. The specific configuration and function of the carbon dioxide generating unit 41 and the unreacted carbon dioxide collecting unit 43, Are omitted since they are the same as described above.

Meanwhile, although the bubble trap 40 of the present invention is designed to maximize the dissolution rate of carbon dioxide, some unreacted un-dissolved carbon dioxide may be generated and the unreacted carbon dioxide may be minimized And then re-dissolving unreacted carbon dioxide and seawater in order to use carbon dioxide effectively.

The carbon dioxide dissolution tank 60 used in the step of dissolving the seawater for circulation and the unreacted carbon dioxide is a device for dissolving the throat such that the mixture of the supplied carbon dioxide and seawater can be moved into a very thin film state, Is formed in the tank main body (61).

After the circulating seawater is mixed with the unreacted carbon dioxide, bubbles of several tens of micrometers in size are generated by a known micro bubble generating device using an ejection method, an acid method, and the like. It is possible to keep the dissolution rate high.

Meanwhile, the amount of carbon dioxide injected from the power plant stack 10 may vary somewhat depending on the seawater temperature and regional characteristics of the seawater. However, after the fourth step, that is, the bubble trap 40, And bubbles generated from the micro bubble generator 80 are dissolved in the seawater so that the final pH can be adjusted to a range of 6.4 to 7.7. If the final pH of the seawater is less than 6.4, the marine life is killed It is preferable to inject carbon dioxide gas so as to be adjusted to the above pH range since the effect of inhibiting the adherence of marine organisms is insufficient when the pH exceeds 7.7.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the scope and spirit of the invention as disclosed in the accompanying claims. And it is obvious that such variations and modifications are included in the appended claims.

<Experimental Example 1>

A laboratory scale apparatus similar to the apparatus shown in Fig. 1 was manufactured, and the seawater was introduced into the bubble trap reactor at a flow rate of 30 L / min while carbon dioxide was supplied from the bottom to dissolve carbon dioxide in the bubble trap. In addition, unreacted carbon dioxide was pumped into the carbon dioxide dissolution tank together with the seawater by using a pump, and then redissolved, and then supplied to a microbubble reaction tank equipped with a microbubble generator.

At this time, the maximum amount of carbon dioxide supplied to the bubble trap reaction tank was set to 200 mg / L, and the dissolution rate and pH of the carbon dioxide discharged from the bubble trap reaction tank and the microbubble reaction tank were measured.

CO ₂ injection amount
(mg / L) CO ₂ dissolution rate (%) pH Bubble trap
Reactor Micro bubble
Reactor Total dissolution rate Bubble trap
Reactor Micro bubble
Reactor 0 0 0 0 8.1 8.1 30 92 8 100 7.4 7.3 50 91 9 100 7.0 6.9 80 89 11 100 6.8 6.7 100 87 13 100 6.7 6.5 140 84 16 100 6.7 6.4 170 81 19 100 6.6 6.3 200 77 23 100 6.6 6.2

As can be seen from the results in Table 1, when the injection amount of carbon dioxide was 50 mg / L, the carbon dioxide dissolution rate in the bubble trap reaction tank was 91% and the microbubble reaction tank was 9%. In this case, the pH in the microbubble reaction tank is 6.9, and it can be understood that the pH of the seawater can be lowered by 1.2 by injecting carbon dioxide.

In addition, when the injection amount of carbon dioxide was 140 mg / L, the dissolution rate was 84% in the bubble trap reactor and 16% in the microbubble reactor. As in the case of 50 mg / L injection of carbon dioxide, the total dissolution rate was 100% It was possible to lower the sea water pH to 6.4.

On the other hand, when the injection amount of carbon dioxide was set to 200 mg / L, the total dissolution rate was 100%, and the pH of seawater was 6.2.

<Experimental Example 2>

In order to examine the effect of preventing the attachment of marine microorganisms according to the change of the amount of carbon dioxide, the rate of prevention of adhesion of marine microorganisms was examined while varying the amount of carbon dioxide injected. The results are shown in FIG.

As can be seen from FIG. 7, as the injection rate of carbon dioxide increased, the effect of preventing the attachment of marine microorganisms was increased. Especially, the effect of preventing the adhesion of 100% was observed at the injection amount of carbon dioxide of 140 mg / L.

Having thus described a particular portion of the present invention in detail, those skilled in the art will appreciate that these specific embodiments are merely preferred embodiments and that the scope of the present invention is not limited thereby, It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the invention, and that such modifications and variations are intended to fall within the scope of the appended claims.
