Description

Seawater vaporization device for making artificial rain clouds and a system for treating harmful fine dust and fallout in the air using the same {Seawater Vaporizer For Making Artificial Rain Clouds And System For Treating Harmful Fine Dust And Fallout In The Air Using The same}

The present invention uses artificial rain created by seawater to remove fine dust and fallout that flows into the airspace of the Korean Peninsula on winds such as westerly winds, and removes harmful fine dust and fallout from the air into the sea. This relates to a seawater vaporization device to create artificial rain that can be safely treated, and a system to treat harmful fine dust and fallout in the air using the same.

In particular, by using a seawater vaporization device consisting of an injector that sprays seawater in the form of fine droplets and a nozzle unit based on the rocket principle that emits fine mist, it instantly vaporizes a large amount of seawater into the air and releases it into a fine mist. This relates to a seawater vaporization device for creating artificial rain that causes fine dust and fallout to form rain clouds that condense and fall into the high seas before reaching land, and a system for processing harmful fine dust and fallout in the air using the same.

In the past 10 years, our country has suffered greatly from fine dust imported from abroad, and in addition, as neighboring countries plan to build more than 150 nuclear power plants, we are exposed to the threat of radioactive fallout from nuclear power plant accidents flowing into the country, but there is no way to deal with this. This is the current reality.

Looking at past cases, in the United States, research was conducted to prevent damage caused by ozone layer holes by forming artificial clouds [1], and in Russia, artificial rain was implemented during the Chernobyl nuclear power plant accident to protect Moscow from radioactive fallout, but it is a landlocked country. Due to the nature of the situation, Belarus, a region where artificial rainfall was implemented, had to suffer greatly as a result. Artificial rainfall technology to date has been implemented by artificially dropping clouds by spreading cloud seeds such as silver iodide on already existing clouds to form condensation nuclei, so in places where clouds have not formed, There are limitations to its use in that it cannot be implemented and rain cannot fall exactly where desired.

In the case of fine dust or radioactive fallout, it has hygroscopic properties, so it can function as a condensation nucleus. Therefore, if it can supply moisture intensively in a short period of time to the sky where fine dust and radioactive fallout exist, it can act as a condensation nucleus for fine dust and radioactive fallout. It can be expected that rain clouds will form and then fall as rain. If these measures are implemented on the high seas before reaching Korea, it is expected that the territory of the Republic of Korea will be more actively protected from fine dust and radioactive fallout.

However, a large amount of energy is required to supply a huge amount of water vapor into the air in a short period of time using seawater on the high seas. However, due to the nature of the distant sea, it will be impossible to draw electricity from land, so it is possible to consider using offshore wind power, wave power generation in the sea, and solar power as energy sources, which are attracting attention for their potential according to global carbon reduction scenarios. there is.

In particular, in the case of wave power generation, high waves in the distant sea are needed for effective electricity production, but the cost of cables to transmit electricity from the distant sea to land is astronomical, so it cannot be used. However, if it is produced on the high seas and consumed as is, it can be a very effective power source. will be.

In the case of offshore wind power, most of it is installed close to land and transmitted onshore through cables. However, if power is generated by offshore wind power on the high seas and this electricity is used as is, this could also be a cost-effective power source.

To this end, if we apply the LNG-FPSO technology of existing offshore plants to create a green hydrogen production base using offshore wind power, solar power, and wave power generation, and build a vaporization device using seawater on this green hydrogen production platform, It is a hydrogen plant that produces hydrogen and supplies it to land via ships, and is expected to secure economic feasibility by having a hybrid function that can be used as a device to vaporize large quantities of seawater in an emergency.

In particular, in order to produce green hydrogen, various compressors, pumps, and turbines must be installed in the hydrogen plant and must always be operated continuously or in hot standby, so these facilities can be directly applied to the seawater vaporization device, and can be used immediately when necessary. Operation will be possible.

The embodiments of the present invention do not limit the scope of the present invention, but are merely illustrative of the elements presented in the claims of the present invention, and are included in the technical idea throughout the specification of the present invention and are elements of the claims. This is an embodiment that includes components that can be replaced as equivalents.

The terms used in the present invention are terms defined in consideration of the functions in the present invention, and may vary depending on the intention or custom of the user or operator, so the definitions of these terms are defined in accordance with the technical details of the present invention. It should be interpreted as a concept.

Additionally, optional terms in the following examples are used to distinguish one component from another component, and the components are not limited by the terms.

First, before explaining the embodiment according to the present invention, looking at Korea's geographical situation, Korea is located in the mid-latitudes of the northern hemisphere and is greatly influenced by westerly winds. Therefore, in order to prevent fine dust and radioactive fallout from flowing in from abroad, an artificial cloud barrier is built in the west coast. Artificial rainfall is the most effective method.

In order to create a cloud barrier 100 meters wide and 400 kilometers long as shown in Figure 11, assuming a strong rain of 10 mm per hour, at least 400,000 tons of water must be vaporized per hour. Trying to evaporate such an astronomical amount of water using heat or electricity would consume enormous amounts of energy, making it very difficult to actually implement it.

However, in the case of the Russian RD-170 engine, a rocket engine can burn by injecting 166 kg of fuel and 432 kg of oxidizer per second. In order to continuously burn such enormous amounts of fuel and oxidant, rocket injectors are specialized in pulverizing liquid fuel and liquid oxidant into fine droplets to make them highly reactive.

If you use this injector to turn seawater into fine droplets (mist), rapidly accelerate them, and release them into the air, you can instantaneously vaporize a large amount of seawater using only the heat of vaporization. Based on the RD-170 engine, which can vaporize about 160 kg of seawater per second per injector, using about 69,500 injectors can vaporize 400,000 tons of water per hour. This amount can be achieved by operating 35 engines based on the RD-170 engine, which consists of 200 injectors. Therefore, if rocket engine technology is used, it will be possible to form a cloud band for artificial rainfall at an economical cost.

The present invention was developed with this in mind, and with reference to the accompanying drawings below, a seawater vaporization device for creating artificial rain clouds created by seawater according to the present invention and a harmful fine dust and fallout treatment system in the air using the same. Examples will be described in detail.

Figure 1 is a cross-sectional view schematically showing only the double swirl injector in the seawater vaporization device for creating artificial rain clouds according to the present invention, Figure 2 is a diagram schematically showing the operating principle of Figure 1, and Figures 3a and 3b are Figure 1 It shows cross-sectional views along lines I-I and lines II-II, respectively.

As shown in the drawing, the seawater vaporization device 100 (see FIG. 4) for creating artificial rain clouds according to the present invention includes a liquid-gas dual swirl injector (hereinafter abbreviated as 'swirl injector') and a dr. It is configured to include a De Laval nozzle (130). First, the swirl injector 110 will be described.

A liquid-gas dual swirl injector, that is, a swirl injector 110, can be used to atomize seawater. This swirl injector 110 provides a compressed air inlet 112-1 and a compressed air outlet 112-2, and compressed air arranged radially at a position adjacent to the compressed air inlet 112-1. A compressed air discharge path (112-5) formed with an annular compressed air injection path (112-4) in which supply nozzles (112-3) are installed, and the compressed air is discharged from the outside of the compressed air discharge path (112-5). It is formed in a state surrounding the furnace (112-5) and located on the inside, and is identical to the compressed seawater inlet (114-1), which is separate from the compressed air inlet (112-1), and the compressed air discharge path (112-5). It has a compressed seawater discharge port (114-2) open in the direction, and a plurality of radially arranged compressed seawater supply nozzles (114-3) are installed at a position adjacent to the compressed seawater inlet (114-1). It includes a compressed seawater discharge path (114-5) formed with a compressed seawater injection path (114-4).

And the air and seawater supply from the compressed air supply nozzle (112-3) and the compressed seawater supply nozzle (114-3) are supplied obliquely in the tangential direction of each discharge path (112-5, 114-5) to compress. Air and compressed seawater were discharged while rotating in the same or different directions along the discharge passages 112-5 and 114-5.

The swirl injector 110 with this configuration has compressed air (gas) and seawater (liquid) formed on the side of the injector 110, respectively, by an air compressor and a pump to be described later, as shown in the drawing. It is supplied fluidly along each discharge path (112-5, 114-5) through the air inlet (112-1) and the compressed seawater inlet (114-1).

At this time, the pressure of air and seawater is supplied at approximately 12 barA, and the gas rotates on the inside and the liquid on the outside along the walls of each discharge passage (112-5, 114-5) of the injector (110). It is directed to each discharge port (112-2, 114-2). Gas and liquid flow while rotating along the walls of each discharge passage (112-5, 114-5) of the injector because the compressed air supply nozzle (112-3) and the compressed seawater supply nozzle (114-3) are connected to each discharge passage. This is because it is installed to be supplied diagonally in the tangential direction of (112-5, 114-5) (see Figures 3a and 3b).

The rotation direction of the air and liquid is rotated in the same or different directions depending on the installation direction of the compressed air supply nozzle 112-3 and the compressed seawater supply nozzle 114-3, while each discharge port 112-2, 114- It can be discharged through 2).

The air and water that flow while rotating at a pressure of 12 barA toward the discharge ports 112-2 and 114-2 along each discharge path 112-5 and 114-5 of the injector 110 are directed to the discharge ports 112-2 and 114-2. They meet each other as they are discharged through the outlet. At this time, the pressurized air discharged through the discharge port 112-2 is discharged with a pulse of approximately 7000 Hz. As it tries to go out in the tangential direction due to centrifugal force, it meets the liquid film sprayed around, so in the cross section, When viewed, the liquid film (film), which is discharged in a cylindrical shape, is struck at an angle, thereby breaking the liquid film itself into fine droplets (see Figures 1 and 2).

An actual double swirl injector was manufactured and an experiment was conducted through the above process, and the results were as shown in FIG. 6. From Figure 6, it can be seen that the liquid film was pulverized into a fine mist droplet.

When using the double swirl injector 110 as described above, in the case of a rocket engine, the rotation directions of the gas and liquid must be matched due to combustion instability caused by perturbation, but in the present invention, combustion occurs. Therefore, there is no need to consider concerns such as combustion instability. Therefore, the liquid film can be efficiently pulverized even if the rotation directions of the gas and liquid are reversed.

On the discharge port side of the double swirl injector 110, air is sprayed under pressure on the seawater that is divided into fine droplets and discharged through the discharge ports 112-2 and 114-2 to create a mistized state in which liquid film formation is suppressed. In addition, by maintaining acceleration by maintaining the differential pressure that is different from the internal and external atmospheric pressure, it is possible to release a large amount of misted seawater into the atmosphere at the speed of sound, creating moisture that can generate rain clouds that condense fine dust and fallout. The De Laval nozzle 130 that acts as a is coupled.

This De Laval nozzle 130 will be described with reference to FIGS. 4 and 5. Figure 4 is a diagram schematically showing the configuration of a vaporization device by combining a de laval nozzle with the double swirl injector shown in Figure 1, and the double swirl injector shows only a portion of the discharge portion. Figure 5 is an enlarged view of a portion of Figure 4.

As shown in the drawing, the De Laval nozzle 130 forms a seawater vaporization chamber 131 with a diameter corresponding to the diameter of the swirl injector 110 and is directly connected to the discharge port side of the swirl injector 110. A fuselage section (chamber 132) capable of being combined with a body portion (132) and a misted seawater formed along the main wall of this body portion (312) and supplied to the vaporization chamber (131) are formed along the body portion (132). ) toward the front end of the fuselage 132 and a plurality of air injection holes 134 that allow air at a predetermined pressure to be sprayed into the vaporization chamber 131 to prevent it from forming a liquid film while flowing along the inner circumferential wall of the A nozzle portion 135 that is gradually narrowed to form a nozzle neck portion 135-1 for accelerating the discharge of misted seawater from the fuselage portion 132 at the speed of sound, and a nozzle neck portion 135-1 from the nozzle neck portion 135-1. It is formed to be open to the outside, but is wider than the diameter of the nozzle neck 135-1 and narrower than the diameter of the fuselage 132, and is formed as a discharge port 136 that quickly accelerates and discharges the mistized seawater into the atmosphere. It is composed.

This de laval nozzle 130 utilizes the characteristics of a convergence and divergence nozzle, and in the subsonic range, acceleration occurs until the fuselage 132 narrows to the nozzle throat 135-1. It reaches the speed of sound (convergence), and is then accelerated to the speed of sound through the widened discharge port 136 of the fuselage 132 and is emitted (divergence).

Therefore, when seawater is injected from the swirl injector 110 at a pressure of 12 barA and air at a pressure of 12 barA into the vaporization chamber 131 of the fuselage 132 of the de laval nozzle 130, In the vaporization chamber 131, it forms an atomization state like fog and flows toward the nozzle portion 135 under pressure. At this time, the inside of the vaporization chamber 131 is the body portion 132. Air having a pressure of 12 barA, which is sprayed from an air sprayer (not shown), is injected from the air injection hole 134 installed along the main wall. The reason for injecting air at a pressure of 12 barA into the vaporization chamber 131 is to prevent the formation of a liquid film on the inner circumferential wall of the fuselage 132 and to prevent the formation of a liquid film inside the vaporization chamber 131 of the fuselage 132. This is to maintain a pressure of at least 9 barA, which is higher than the external atmospheric pressure.

The reason for maintaining the vaporization chamber 131 and the external atmospheric pressure and the differential pressure (9 barA or more) is that the fine droplets (mist) sprayed into the vaporization chamber 131 create an atmosphere with a lower air pressure than the inside of the fuselage 132. The purpose is to accelerate toward the discharge port 136 of the fuselage 132 to reach the speed of sound through the nozzle neck 135-1 and then discharge it into the air at high speed. The mist, which is accelerated and released from the nozzle 130 at the speed of sound, is instantly vaporized into the air when it comes into contact with air, which can have the effect of evaporating a large amount of seawater.

When the seawater vaporization device 100 instantly vaporizes a large amount of seawater and releases it into the air, the moisture at this time can serve as a raw material for forming rain clouds. The rain clouds formed in this way are fine dust in the air. And it can act as a condensation nucleus that condenses fallout, acting as an artificial rainfall that causes fine dust and fallout to fall on the high seas in advance, making it possible to be safe from the risk of fine dust and fallout on land.

Figure 7 is a photograph of a liquid film formed on the wall of the body part 132 of a DeLaval nozzle when seawater is sprayed from the injector 110 to examine the characteristics of the liquid film formation on the wall.

It can be seen that when the liquid droplets hit the inner wall of the body 132, they stick to the wall rather than bounce off, forming a liquid film and flowing down the chamber wall.

If a liquid film is formed in this way, seawater cannot be effectively vaporized, so measures to prevent the formation of a liquid film are necessary. Therefore, instead of the chamber having the structure shown in Figure 8, a pressure of 12 barA, which is the same as compressed air, is injected from the injector 110 on the main wall of the body 132 as shown in Figures 4 and 5. By coating the inner circumferential wall of the fuselage 132 with an air layer to form a boundary and crushing the liquid droplets that try to stick to the inner circumferential wall, the interior of the fuselage is filled with fine droplets maintaining a pressure of at least 9 barA to prevent rain clouds. Create a favorable mist environment, which is the raw material for formation.

Figure 9 is a block diagram showing the configuration of a system for treating harmful fine dust and fallout in the air using a seawater vaporization device to create artificial rainfall according to the present invention.

As shown in the drawing, the harmful fine dust and fallout treatment system 200 in the air using the seawater vaporization device according to the present invention includes a solar power generator 201a and an offshore wind power generator 201b installed in the form of an offshore platform on the high seas. and a wave power generator (201c), and some of the new and renewable energy obtained from the generator is stored in an electric power storage system (ESS) (202) linked to each of the generators or provided to the green hydrogen production facility (203) to produce green energy. Makes it possible to produce hydrogen. In normal times, hydrogen gas produced in the green hydrogen production facility (203), which is a green hydrogen production plant, is connected to the power storage system (ESS) (202) and the green hydrogen production facility (203) and compressed air is supplied to the seawater vaporization device (100). The air compressor (205) and seawater pressurization pump (206), which supply compressed seawater, respectively, and the hydrogen gas compressor (204-1) of the hydrogen gas power generation unit (204) are constantly operated and connected to the hydrogen gas compressor (204-1). Electricity is produced by operating the generator (204-3) using the hydrogen gas turbine (204-2) of the micromix combustion method as the main power.

That is, the pressure pump 206, air compressor 205, and hydrogen gas compressor 204-1 are operated with the power obtained from the ESS and the hydrogen turbine, and the hydrogen compressed in the hydrogen gas compressor 204-1 is It can be stored in the hydrogen storage facility (207) connected to the hydrogen gas compressor (204-1) and sent to land using a hydrogen carrier, etc.

The hydrogen gas compressor (204-1) and the air compressor (205) are connected to the hydrogen gas turbine (204-2) of the hydrogen gas power generation unit (104) in the hydrogen gas compressor (204-1). Compressed hydrogen gas and compressed air compressed in the air compressor 205 are used together to operate the hydrogen gas turbine 204-2. At this time, the exhaust heat generated from the hydrogen gas turbine (204-2) is recovered through the waste heat recovery boiler (WHRU) 210 connected to the hydrogen gas turbine (204-2) to generate steam required for the waste heat demand source (211). The moisture generated from the waste heat demand source (211) is condensed through the condenser (212) and then supplied to the waste heat recovery boiler (210) through the feed water pump (213) to form a cycle in which it can be reused. .

The air compressor 205 and the seawater pressure pump 206 are connected to the seawater vaporization device 100 to supply a large amount of moisture necessary for forming a cloud zone to create artificial rain toward the seawater vaporization device 100 (see FIG. 4). Pressurized air and seawater are supplied to create and evaporate continuously into the air. That is, the air compressor 205 and the seawater pressure pump 206 inject air and seawater into the fuselage of the DeLaval nozzle 130 through the swirl injector 110 of the seawater vaporization device 100 at a pressure of approximately 12 barA, respectively. It is sprayed into the vaporization chamber 131 of the chamber 132.

The inside of the vaporization chamber 131 of the fuselage (chamber 132) can maintain a pressure of approximately 10 barA by pressurized seawater and compressed air at 12 barA injected by the swirl injector 110. At this time, the swirl injector 110 For the purpose of preventing the fine droplets of seawater sprayed in an atomized state from (110) from hitting the inner circumferential wall of the fuselage portion 132 and condensing back into a liquid state while forming a liquid film, the fuselage portion ( 132), compressed air of approximately 12 barA is sprayed using a conventional air sprayer (not shown) through air injection holes 134 (see FIGS. 4 and 5) formed at regular intervals along the entire main wall of the fuselage. By forming a boundary layer (coating layer) of air on the inner circumferential wall of the chamber 132, the formation of a liquid film along the inner circumferential wall of the chamber 132 is prevented and the inside of the vaporization chamber 131 of the chamber 132 is prevented. By creating a pressurized state full of fine droplets maintaining a pressure of 10 barA, the vaporization chamber 131 of the fuselage 132 and the external atmospheric pressure are maintained at a difference of at least 9 barA or more. .

In this state, the pressurized fine droplets are driven through the convergence area of the nozzle neck 135-1 due to the convergence-divergence nozzle characteristics of the DeLaval nozzle 130 and are accelerated to at least the speed of sound while forming the discharge unit 136. ) to release fine droplets into the air at the speed of sound (see Figure 4). This condition continues as long as seawater and air are supplied.

Fine droplets accelerated beyond the speed of sound are quickly vaporized into the air and spread into the air, supplying moisture, which is the material for rain clouds. In the process of spreading into the air, when they encounter fine dust or fallout layer, the moisture becomes condensation nuclei that condense the fine dust and fallout layer. By acting as a condense and forming a rain cloud band that causes strong rain, it is possible to cause fine dust or fallout layers to fall on the high seas before reaching land, thereby minimizing pollution on land due to fine dust or radioactive fallout. You can.

Figure 10 is a block diagram schematically showing a meteorological satellite communication network that provides cloud generation location information linked to the system of Figure 9.

As shown in the drawing, a communication information network can be formed with the marine platform of the harmful fine dust and fallout treatment system 200 in the air using a seawater vaporization device installed at sea and the Cheollian weather satellite 300. Building a communication information network with the Cheollian weather satellite 300 can identify the rain cloud generation point (P) formed by the system 200.

Based on data on the rain cloud generation point (P) tracked and observed by the Cheollian weather satellite 300, the marine platform of the system 200 is quickly towed and moved at sea to create rain clouds that can create artificial rainfall. It can help create more effectively.
