Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The disclosed technology belongs to the structural technical field of an airship that mass-transports carbon dioxide gas generated from a power plant or the like to a predetermined treatment facility in a gaseous state.

[0002]

2. Description of the Related Art As is well known, energy is indispensable for so-called industries, and in most cases, the form of supplying the energy depends on electric power from a power plant.

Although there are hydroelectric power plants, nuclear power plants, thermal power plants, etc. in the power plants, there are geographical restrictions in the hydropower plants, and in the nuclear power plants. Is restricted by the residents' resistance in terms of safety. Therefore, fossil fuels such as petroleum and coal have various advantages such as freedom of installation and easy operation and management with highly complete technology. The mainstream is the thermal power plant by
A large amount of petroleum and the like is used in terms of transportation and cost of the fuel used and ease of handling.

By the way, in recent years, not only in the pursuit of productivity in various industries, but pollution problems and environmental harmony problems cannot be ignored, and the target is closed not only locally but also on a global scale. It has been uploaded.

In a thermal power plant, for example,
A trial calculation of carbon dioxide emissions from a 1 million kW thermal power plant yields 200 tons per hour and 20 per day.
It is a large amount of emissions such as 00 tons, which cannot be ignored from the viewpoint of environmental pollution on a global scale as well as pollution problems.
As a matter of course, it is necessary to carry out a treatment to prevent pollution and prevent environmental damage, and inevitably a large amount of carbon dioxide gas is emitted. Due to pollution problems, etc., the extraction / separation technology of the carbon dioxide gas will be used in recent years. The carbon dioxide treatment facility, which was researched and developed and separated and extracted, is installed at a site that is separated from the normal power plant by a considerable distance from the viewpoints of location restrictions, independence as a business, and environmental pollution control. In most cases, it is necessary to transport the carbon dioxide gas separated and extracted at the power plant to the treatment facility.

[0006] Therefore, generally, regarding gas transportation, it may be considered to be liquefied and transported by ships, tank trucks, etc. from the economical and technical point of view, but usually by land transportation by tank trucks, etc. In most cases, a mode in which marine transportation by a ship is intervened during this is general.

By the way, as mentioned above, 2000 per day
To transport a large amount of tonnes of carbon dioxide to a treatment facility by tank truck, etc., for example, a 7-ton tank truck is used, and as many as 300 reciprocating operations per day with a treatment facility per thermal power plant. It is necessary, and problems such as traffic congestion, securing workers such as engineer workers, and economic efficiency cannot be avoided.

Considering the cost, which is the biggest bottleneck, the liquefaction of carbon dioxide gas requires 10 power generation costs.
In Japan, which consumes -20% of the cost and consumes liquefied energy, it is a non-negligible loss in Japan, and it has a drawback against energy saving.

Therefore, considering the gas transportation from each power plant to the treatment facility, in the case of mass transportation in terms of its transportation mode, depending on the route, the airship is more advantageous than the ship etc. by taking advantage of the straight transportation. Yes,
For the idea of this point, see, for example, JP-A-63-121.
As disclosed in Japanese Patent No. 598, a gas chamber for a gas lighter than air such as hydrogen or natural gas is provided in a chamber of an airship, and one kind of a predetermined gas is filled in the gas chamber for flight, and the facility is treated. There is a disclosure that the gas is extracted and collected, the technology is not limited geographically, the number of transportations can be increased, and there is a merit in terms of facility and economy.

Such an airship does not require a road or the like for mass transportation of gas although it is a single type of gas, has a high degree of freedom in transportation, and does not take a heavy-structure transporter such as a ship, and is relatively free to navigate. It has excellent features such as easy operation.

[0011]

Meanwhile, in the gas transportation mode of the airship disclosed in the related art, the airship of the airship is the same gas as the levitation gas and the transportation gas, and the levitation gas is separately provided on the return path. However, there is a problem that carbon dioxide gas cannot be transported because only hydrogen or natural gas, which is lighter than air, can be transported.

Therefore, there is a minus point that cannot be put to practical use for transportation from a power plant to a treatment facility for a large amount of carbon dioxide gas generated.

[0013]

OBJECT OF THE INVENTION The object of the invention of this application is to solve the problem of mass transportation by airship to the next-stage treatment facility of carbon dioxide gas generated in large quantities from the thermal power plant.
While taking full advantage of the transportation by the airship, it is easy to hold and store the floating gas such as helium, the transported gas such as carbon dioxide, and the balancing air, and the shape retention is good, as well as the forward transportation route. In this way, an excellent airship structure for gas transportation that can be smoothly navigated even on the return path and can be reliably transported regardless of the type of carbon dioxide gas and which will benefit the field of processing technology application in the energy industry It is intended to be provided.

[0014]

In order to solve the above-mentioned problems, a large amount of carbon dioxide gas is generated from a thermal power plant in order to solve the above-mentioned problems. When intermittently transporting a large amount of a predetermined amount to a treatment facility installed a predetermined distance apart, when transporting by an airship that floats by a gas such as helium and travels, a film body stretched laterally in the outer skin of the airship. The upper part of the levitation gas chamber and the lower part of the non-floatation gas chamber are enclosed by the levitation gas chamber, and the levitation gas chamber is filled with levitation gas such as helium to levitate the airship. A gondola is hung on the lower end of the body via a hanging rope so that the levitation force and weight cancel each other out in each cross section so that the shape retention of the airship is always maintained and a good balance can be maintained. Regarding the chamber, The inner membrane is divided into an upper air chamber and a lower transported gas chamber to maintain the internal pressure balance.For the lower transported gas chamber, the membrane is divided into a plurality of chambers to balance the pressure before and after. It is a technical measure taken to keep it.

[0015]

Embodiments of the invention of this application will be described below with reference to FIGS. 1 to 5.

The illustrated embodiment is an embodiment of an airship used for transporting a large amount of carbon dioxide gas generated by fossil fuel combustion in a thermal power plant to a treatment facility that is separated by a predetermined distance. The embodiment shown in FIGS. 1 is a teardrop-type airship that forms the center of the invention of this application, and a flexible outer skin 2 is provided with a mooring metal fitting 3 at a tip portion thereof, and a rudder 4 is provided at a rear portion thereof. A vertical stabilizer 5 is erected, and horizontal stabilizers 7, 7 having elevators 6 are laterally installed at a right angle to the vertical stabilizer 5, and a passenger, engine room, and ballast are provided in the lower central portion. A gondola 8 (which may be equipped with a liquefied gas chamber) having a tank is provided, and ducted fan type propulsion devices 9 are provided on both sides of the engine chamber.

The external structure of such hardware is substantially the same as that of the conventional airship, and in the invention of this application, the chamber 10 in the outer cover 2 of FIG. A substantially triangular sagging film body 1 made of a synthetic resin is provided along the longitudinal direction at the top of the outer skin 2.
A predetermined number of plural upper edge portions are fixedly attached to the outer skin 2 in a predetermined manner, and suspended from the lower end thereof.
12 ... are connected to suspend the gondola 8 so that the shape retention is maintained.

In the chamber 10, a lateral membrane 13 made of a flexible synthetic resin or the like is used to store a floating gas storage chamber 14 such as helium in the upper portion and a non-floating gas chamber in the lower portion. 15 are mutually sealed airtightly.

Then, in the non-floating gas chamber 15, two film bodies 16 made of synthetic resin or the like are longitudinally arranged at a predetermined interval.
6 is stretched and the front, middle and rear sections (a),
(B) and (c) are defined as three chambers, and further, in the non-floating gas chamber 15, the film bodies 16 and 16 and the outer skin 2 are adhered to each other in a sealed state with flexibility. That is, the foldable film body 17 is stretched in a horizontal state and the inside of the non-floating gas chamber 15 is provided with the shape maintaining property and the pitch trim function of the upper air chamber 18 and the lower transported gas. The chamber 19 is divided into three chambers 19 19 ′ and 19 ″, and each is filled with a predetermined amount (predetermined pressure) of carbon dioxide gas so that the airship 1 can maintain a longitudinal balance.

The structure of the non-floating gas chamber 15 will be described in more detail. The cross-sectional characteristics of the non-floating gas chamber 15 are as follows: below the film body 13, along each suspension line 12 and in the same plane as the suspension line 12. The direction separating film bodies 20, 20, ...
3, the non-floating gas chamber 15 is divided into five chambers in the lateral direction in FIG. 3 by the membrane units 20, 20 ... Each chamber is made up of a flexible membrane 17 and has an upper air chamber 18 and lower transported gas chambers 19, 19.
It is divided vertically into ', 19''.

Further, in each of the front and rear chambers, as shown in FIG. 4, since the flexible film bodies 17 may be one set, the structure is simple, and the air chamber 18 and the transported gas chamber 19 are also the same. , 19 ',
19 '' is separated into upper and lower parts.

Although not shown, an appropriate air intake / exhaust duct is provided in the air chamber 18 so as to control the inflow / outflow of air from the outside atmosphere as necessary.

In the above-mentioned structure, the airship 1 is charged by the mooring metal fitting 3 into a predetermined portion of a thermal power plant (not shown) and in the levitation gas chamber 14 with helium as a levitation gas of a designed volume at a predetermined pressure by a filling device (not shown). At the same time, a predetermined amount of balancing air is pressed into the air chamber 18, and
The extracted carbon dioxide gas is filled in each of the lower transported gas chambers 19, 19 ′, 19 ″ so that the front and rear of the airship 1 can be balanced and shape retention can be maintained.

During this time, the airship 1 is gradually levitated by the helium in the levitating gas chamber 14, but in the gondola 8, the catenary curtain 11 fixed to the inner surface of the top of the outer skin 2, that is, the inner top surface of the chamber 10. , 11, ... and
Since it is suspended by the suspension lines 12, 12, 12 provided below the lower end thereof, the weight thereof is applied to the entire outer cover 2, so that the shape retention of the cross-sectional shape as designed is maintained.

The airship 1 has ducted fans 9,
The ship navigates to a predetermined treatment facility at a low altitude by 9 and is moored by the mooring metal fittings 3 to be transported gas chambers 19, 19 ',
The carbon dioxide gas in the 19 "is extracted and subjected to a predetermined treatment. On the return route, the transported gas chambers 19, 19 ', 19" are filled with air, and the ballast tank in the gondola is filled with appropriate water or the like. When fully loaded, the boat will sail in an appropriate balance and be ready for the next transportation.

Another embodiment of the non-floating gas chamber 15 shown in FIG. 5 is the same as the above-described embodiment above the dividing film body 13, and the non-floating gas chamber below the film body 13. Numeral 15 is provided laterally on the same plane as the suspension line 12 of the gondola 8, and its outer periphery is joined to the outer skin 2 by three semicircular separation membranes 1.
6, 16 ', 16''are divided into four chambers in the front-rear direction, and each chamber is also vertically divided into an air chamber 18 and a transported gas chambers 19, 19', 19 '' by a separating film body 17. ing.

The shape of the separating film body 17 in this case is as shown in the drawing in the entire cross section.

Of course, the embodiment of the invention of this application is not limited to the above-mentioned embodiments. For example, in addition to the soft airship in which the outer skin of the above-mentioned embodiment is formed of a flexible film body, When a hard airship with a light metal or a flexible film outer shell can be used, or when the transport gas can be mounted only a little due to the design, for example, the non-floating gas chamber (section (b)) in FIG. It is possible to employ various modes such as filling the levitation gas with the levitation gas.

Further, it goes without saying that the gas to be applied is not limited to carbon dioxide gas but can be applied to gases such as LNG and LPG.

However, when a gas lighter than air is transported,
First, there is a floating gas volume such as helium for the return path, and when the volume for the transported gas at atmospheric pressure is added to this, the volume of the airship 1 becomes larger than that for gas transportation that is heavier than air, and the air resistance, engine horsepower, etc. Since it becomes large and uneconomical, it may be economical to mount the liquefied gas in the gondola 8.

That is, the question is whether the economic loss of liquefaction of the transported gas or the economic loss of navigation is large. In practice, a certain transportation distance is set as a branch point, and gaseous transportation is performed at a short distance, and in a long distance. Liquefied transportation is a better option.

In response to such a situation, a gas transport airship that enables both gaseous transport and liquefied gas transport using the gondola 8 is also within the technical scope of the present invention.

[0033]

As described above, according to the invention of this application, basically, when a large amount of gas such as carbon dioxide gas generated from a thermal power plant or the like is transported from a generation source to a next stage treatment facility, the chamber in the airship is concerned. By filling and storing gas and transporting it,
There is an effect that a large amount of gas can be safely and efficiently transported all at once, and there is no restriction on traffic such as using land and sea routes, and it is possible to navigate relatively freely, therefore,
It is efficient and can be transported at low cost.

Since the gas can be filled and transported by being divided into a plurality of chambers through the film body in the chamber, the balance between the levitation gas and the air can be maintained and the levitation force and the gravity in the entire cross section can be canceled out. A moment like a hot air balloon does not work,
Shape retention is also maintained, and there is an effect that stable transportation is possible.

As a chamber structure, a flexible gas-tight film body is formed between an upper levitation gas chamber and a lower non-floating gas chamber to separate and extract gases such as carbon dioxide gas from the air. It has the effect that it can be transported in the state of being separated and extracted while avoiding the mixed state with the levitation gas, and also has the merit that it is easy to perform a predetermined treatment even at the treatment facility of the destination.

Furthermore, since the chamber can be vertically and laterally divided into a desired number of chambers through flexible airtight membranes, the pressure in the chamber can be maintained at the set pressure, and the cross-sectional shape of the airship can be maintained. There is an effect that can be surely achieved.

In gas transportation, energy is not used for liquefaction, which is extremely economically advantageous.
