Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of forming a block using coal ash or other waste, installing the block on a continental shelf or the like, and breeding, breeding and new reefs for migratory fish and other fish. The present invention relates to blocks, fish reefs and construction systems using coal ash and other wastes and by-products for the purpose of creating a marine ecosystem, and a system for breeding marine resources.

[0002]

2. Description of the Related Art Conventionally, it has been known that concrete blocks are installed along the coast to form a fish reef. Further, a porous molded body for growing aquatic organisms in which a gypsum-containing silicon-containing pellet is consolidated by a binder has been proposed (Japanese Patent Application Laid-Open No. 7-5).
0952).

[0003] Next, as an invention using sulfur as a solidifying material, a composition using sulfur and asphalt is used, and a roadbed material, an aggregate, and a building material using coal ash, combustion ash, FCC waste catalyst, and the like. Has been proposed (JP-A-9-194737).

[0004] Further, there is known an invention of a sulfur composition comprising a mixture of sulfur and a mineral fine powder. Using this sulfur composition, high-strength sulfur concrete can be produced. (JP-A-11-349372).

[0005] Next, a soil solidifying agent, which is a composition comprising silicon oxide, aluminum oxide, calcium oxide, sodium aluminate, magnesium oxide and sulfur oxide, has been proposed (JP-A-8-165467).

[0006] Further, as for the invention of ocean dropping, as an invention for constructing a structure systematically, when there is no flow (natural fall) due to the depth of water at the place where earth and sand, stones and the like are put in and the size and shape of the earth and sand and stones, etc. Predict and estimate the state of sedimentation at the bottom of the water, calculate the sedimentation shift of sediment, etc. injected by the flow, move the input position by that amount and correct it, and sediment, stones, etc., which accumulate in the correct shape (Japanese Patent Laid-Open No. 11-81316) has been proposed.

[0007]

Since the conventional fish reef aims at a relatively shallow sea (for example, at a depth of about 10 m), it cannot be used in many cases where the installation location is more than 50 m.

[0008] The strength of the sulfur concrete block utilizing industrial waste is unknown, except for the invention of a sulfur composition using a fine mineral powder (the invention of Japanese Patent Application Laid-Open No. 11-349372). When installed, the reliability of cracks and other destructive forces is unknown, but the invention of Japanese Unexamined Patent Application Publication No. 11-349372 can be sufficiently used for implementing the present invention.

Japanese Patent Application Laid-Open No. H11-81316 discloses a method of dumping sulfur concrete blocks into the ocean. However, in view of the variety of dumping methods, it is an effective method for dumping.

[0010] Since the above-mentioned fish reef is permanently left on the seabed, elution of harmful substances is not allowed in any state. Particularly, in the case of coal ash and other incineration residue ash, since various substances (hazardous heavy metals and the like) are also contained, the water pressure at the sea bottom (for example, a water depth of 100 m to 200 m) is used.
The physical properties when exposed to seawater under a temperature of 10 to ²⁰ kg / cm < ² > for many years where temperature change is possible must be sufficiently studied.

Next, when dropping into the ocean, it is possible to use a small amount,
Since necessary effects (for example, the height of the upwelling current) must be obtained, the outer shape as simulated must be maintained without sinking or collapse. Therefore, if the seabed is rocky, it is necessary to predict the displacement when subjected to external force, and if it is sandy ground, it must be subjected to heavy pressure and to prevent settlement when vibrated by external force. If it is relatively lightweight and is deposited on a flexible structure, there is no possibility of sinking due to heavy pressure and resilience to deformation due to external force is given to prevent breakage.

In general, it is difficult to effectively use industrial waste because, despite the fact that mass processing and mass use are economical, the accumulation of waste and the transportation of the product to the place of use are economically balanced. Because there is no.

In the present invention as well, coal ash and sulfur are generated at different places, so they must be efficiently collected, and the manufactured sulfur concrete block is generally used at a distant place. If the quantity is sufficient, it will be completely useless afterwards, so there is a problem of supply unnecessary which is no different from that of general buildings after the construction is completed.

[0014]

SUMMARY OF THE INVENTION In view of the fact that wastes are constantly generated in large quantities and the use of sulfur concrete blocks is almost infinite, the present invention is intended for selection of a manufacturing place, collection and transportation, and the like. If you do not make mistakes in planning and management, you can continue for more than several decades and become a global business.

[0015] That is, the invention of the block is that one or more kinds of coal ash, slag, marine waste and other wastes are used as they are, or a main aggregate obtained by pulverization and a solidifying agent are mixed with a solidifying agent to form and solidify. It is a block made of coal ash and other wastes and by-products, and the marine waste is oyster shell, scallop or other shells. In the solidification molding, sulfur is used as the solidification material, and the powder obtained by pulverizing the sulfur and the marine waste is heated, kneaded in a temperature range of 110 ° C to 150 ° C, and formed into an arbitrary shape. The solidification is molding using a mold, vibration molding, pressure molding, or vibration / pressure molding.

Further, blast furnace slag 70% -30% (mass), coal ash 20% -1%

Next, the invention of the fish reef group includes a coal-fired power plant and other coal ash and other waste generated by burning coal,
Coal ash and other waste and by-products, which are characterized by being made into a fish reef by constructing a sulfur concrete block manufactured at a predetermined height and width on the continental shelf at the appropriate position on the continental shelf using recovered sulfur generated during oil refining The fish reef group used, and the sulfur concrete block is a block or briquette, and is mainly composed of 10% to 60% (mass) of heated molten sulfur and 90% to 40% (mass) of coal ash, and is uniform. Mix,
Molded and solidified. The fish reef is located at a relatively shallow place on the continental shelf at a height of 5 m to 30 m and a bottom area of 100 m ² to
100,000 m ^{2 of} an arbitrary-shaped structure,
%, And said fish reef is formed at a height which can form a flow direction of seawater to a relatively deep place on a continental shelf and can induce an upwelling flow. Fish reefs using other waste and by-products,
The height at which the upwelling can be induced is 10% or more of the water depth.

Further, the sulfur concrete block is one in which waste and other fillers are provided inside a sulfur concrete box, and the waste includes, for example, incineration ash, incineration sludge,
Various types of powdered industrial waste such as molten slag, sedimentation sludge, and waste catalyst, and other fillers were briquettes made of coal ash or slag, concrete waste, gravel, or slag. It is.

Next, the invention of the system is to produce coal concrete ash and sulfur through a means of transporting coal ash and the like (including briquettes) from a place where coal ash is generated and a means of transporting sulfur from a place where sulfur is generated. While being transported to the factory as quantitatively as possible, a sulfur concrete block having a predetermined shape is manufactured at the factory, the sulfur concrete block is transported to a predetermined sea area by a transport means, and the sulfur concrete block is previously indicated by a charging means. It is a system for constructing a reef group using coal ash and other waste and by-products, characterized by dropping the indicated quantity to the designated sea area by the indicated method and constructing the reef group at the set density and height, Coal ash and sulfur are transported through a means of transporting coal ash from the area where coal ash is generated and a means of sulfur transport from the area where sulfur is generated. Narukaku with quantitatively transported, manufactured sulfur concrete blocks of a predetermined shape 該工 field,
The sulfur concrete block is transported to a predetermined sea area by the transportation means, and the designated quantity is dropped by the sulfur concrete block charging means to the designated sea area by the instruction method, and the fish reef having the length and height of the upwelling flow is generated. This is a fish reef construction system using coal ash and other wastes and by-products, characterized by the construction of a group.

The means for transporting coal ash and the like and the means for transporting sulfur are transported by pipe, vehicle or ship, and the factory for producing sulfur concrete blocks is transported on land or offshore.

Further, the invention of the method is a method for breeding marine resources, which comprises setting up a fish reef group comprising the sulfur concrete block and arranging a seaweed cultivation block to create a new rocky ecosystem. . The above-mentioned fish reef group is set up in a sea area where a new ecosystem is created, and an induced sea area by the fish reef group is constructed between the sea area where the new ecosystem is created and the marine ranch. In another invention, the seaweed breeding block is characterized in that the seaweed cultivation block is formed and solidified with an enzyme-treated product of waste or an enzyme-treated product such as food residue during processing of fish, and coal ash, slaked lime and a binder. Is the way. In the above invention, coal ash, incinerated ash (including city incinerated ash, domestic incinerated ash), sludge, waste catalyst and marine waste (oyster shell, scallop and other shells) as industrial waste, and sulfur as by-product However, as described in the above-mentioned known example, it is not necessary for the binder to be sulfur alone if it has the same strength as sulfur and is non-toxic.

The object to be solidified is not limited to coal ash or incineration ash, but it is necessary to prevent harmful substances from being eluted or to prevent harmful substances from being eluted. Furthermore, even if hazardous waste is enclosed in the sulfur concrete block of the present invention and proved that it is never destroyed, all industrial waste can be used as a block in the state of inclusion. .

In such a case, it is of course possible to effectively utilize the fish as a reef, and a mountain range may be formed on the deep sea floor as a mere drop.

In the above invention, 1% to 5% (by mass) of calcium hydroxide is added to prevent elution of dents. Further, if 1% to 5% (by mass) of sodium sulfide is added, sulfide can be generated and elution of harmful substances can be prevented. Further, if crude oil of 1 to 5% (mass) is added as a dispersant, it is possible to prevent the crystal of sulfur from becoming large and to maintain the strength of the block.

The specific gravity of the block according to the present invention varies depending on the material used, but the specific gravity is preferably higher because it is discarded into the sea. For example, coal ash and sulfur are 50% ×
The specific gravity at 50% is about 1.7, which is close to the lighter limit. Therefore, it is desirable to mix a relatively heavy material (2.0 to 3.0) such as slag, incinerated sludge, and steelmaking slag to an appropriate amount, and adjust the specific gravity of the block to about 2.0 to 2.5. However, if a briquette having a high specific gravity is used as the core of the block, the specific gravity can be set to 3.0 or more.

When the input site is located at a long distance, heating and mixing of coal ash and sulfur in the existing block manufacturing plant do not directly produce blocks of a predetermined size, thereby stabilizing them. Processing, processing into briquette, gravel and granular solids that are convenient for storage and long-distance transport, and a simple block manufacturing plant (heating / kneading / casting plant) near the block loading site Is installed and a block is manufactured, whereby a more rational construction system can be obtained.

When forming the seaweed cultivation block, the block should not be easily collapsed by waves.
For example, 0.3 to 1.5 parts by mass of cement mortar is mixed with 0.5 to 1.0 parts by mass of fish waste, 1.0 part by mass of briquettes and other calcium particles, and molded.

[0028]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention is a sulfur concrete block formed by solidifying coal ash, marine waste, and other industrial waste with sulfur, and is used for a fish reef. Therefore, the shape of the sulfur concrete block is not limited, and the first condition is that the block can be stably deposited on the sea floor. Further, the present invention relates to a fish reef group, a construction system thereof, and a marine resource propagation method for constructing a continuous structure on the sea floor using the sulfur concrete block. This continuous structure creates an upwelling at the right place on the continental shelf, supplying nutrients in the seawater to the euphotic layer on the sea surface, breeding plankton, growing seaweed, and creating new reefs. The aim is to create an ecosystem and supply nutrients that can withstand it.

The sulfur concrete block is molded and solidified in a land-based molding plant (or a molding plant on a ship) that collects coal and ash, marine waste, other industrial waste, and sulfur, and uses a gravel dropping ship or the like. The above purpose is achieved by dropping the fish on the continental shelf at the appropriate location and creating a fish reef group or building a submarine mountain range.

[0030]

Embodiment 1 The present invention will be described with reference to FIGS.
It transports coal ash, which is the combustion residue from thermal power plants, to the sulfur concrete block molding plant built near the coast, and also transports sulfur recovered from oil refineries. The coal ash is performed like handling, transport and storage of powder,
The sulfur is subjected to a raw material transporting step like handling, transporting and storing liquid sulfur, and then fixing and stabilizing the coal ash by heating and mixing sulfur and coal ash and suppressing and stabilizing the release of harmful substances. After the steps, a block manufacturing step is performed. In this case, it is processed and formed into a predetermined strength and shape.

The sulfur concrete block (hereinafter, referred to as a block) that has passed through the above steps is dropped to manage the fish reef at a predetermined position and in a predetermined shape, and the step of dropping, depositing and building is completed. The above is the case of constructing a reef mountain range for generating an upwelling flow. When a large number of reef groups are constructed at a predetermined density, a predetermined amount (for example, 500 tons to 1
In some cases, it may be sufficient to drop a block of (000 tons).

When a block forming factory is constructed close to a thermal power plant where coal ash is emitted, pipe transportation may be used. After adjusting the particle size of the coal ash to a certain range (for example, 100 μm is 50% or more) by a ball mill or the like in order to obtain a high-density solidified material,
The mixture is heated to 5 ° C., and the sulfur is heated and liquefied (for example, 125 ° C.), uniformly mixed by stirring while adding an equal amount thereof, and the mixture is transferred to a pressure molding machine. , 0.
After applying a pressure of 05 N / mm ² , vibrating and consolidating, cooling to 20 ° C. and demolding, a block used in the present invention is obtained (FIG. 3). The shape of the block 1 is determined by the type of the molding machine and is various, but in consideration of easiness of handling, stability as a fish reef, ease of attitude control at the time of dropping, etc., for example, FIG. , (B), but there is no restriction on the shape. Although the specific gravity is about 1.5 to 2.0, in order to make it relatively heavy, waste having a large specific gravity (various metals and slags) is mixed as an aggregate of sulfur concrete, or waste 2 ( For example, various metals) may be provided inside the outer shell 1a of sulfur concrete. In such a case, an arbitrary specific gravity can be selected, and the waste can be safely treated. The interior material is hardened into briquettes with sulfur concrete to prevent elution of harmful substances.

The block 1 has a thickness of 15 to 30 N / mm ^2.
Because of its compressive strength, there is no danger of breakage due to wave force etc. even if it sinks on the sea floor.

The block 1 is loaded on the drop ship 3 and transported to a predetermined sea area on the continental shelf and dropped. At the time of the drop, the position of the drop ship 3 must be accurately managed.
As an example, the satellites 5 are used to manage the injection in real time under the close link with the instructions of the land base station 4 and the computer 3b in the cab 3a of the drop ship 3. Next, the shape management of the fish reef 6 of the block 1 put in is carried out by transmitting ultrasonic waves from the oscillator 8 of the survey ship 7, grasping the shape of the accumulation block 6a every time the dropping is completed, and incorporating it as management data at the time of the next drop. (FIGS. 5 and 6).

When a fish reef group is constructed in a certain sea area of the continental shelf 9, a position in the sea area is regulated, and a predetermined amount (for example, 10,000 tons) is dropped at each dropping position. Since a group is formed, the purpose can be sufficiently achieved by mainly controlling the input position during the input management of the drop ship 3.

On the other hand, regarding the construction of the fish reef mountain range 6b for generating the upwelling current, the size thereof is, for example, 120 m in width, 40 m in height, and 300 m to 400 m in water at a depth of 150 m.
Therefore, in order to improve the efficiency, the input management and the data management are strictly performed, and the construction cost and the like are minimized.

In the above, if there is an ocean current as indicated by an arrow 10 in FIG.
As shown by arrows 1a, 11b, 11c, 11d, and 11e, vortices are generated, and ascending and descending are repeated, and ascending sequentially.
Move in the directions of 2 and 13. 14 in the figure is the water surface,
The eutrophic seawater that was in the relatively deep part A rises to the water surface due to the upwelling and generates a large amount of phytoplankton by photosynthesis, so that fish 15, 15 gather, grow and breed fish, and The area can be fish-inhabiting or migratory.

In the above embodiment, the gravel drop ship 3 is assumed to transport the manufactured blocks to the reef sea area in need (FIG. 5), but there are no restrictions on the method of transporting and dropping the blocks. A method that is feasible, safe, suitable for mass transport, and easy, simple and reliable in loading and dropping is preferred. Therefore, in addition to the gravel drop ship 3, the following method can be considered. A method of lifting a plurality of block groups 17 with a crane 18 and dropping the block groups 17 as they are into the sea instead of the gravel drop ship 3 instead of the luggage ship 3 can collectively drop each block into each block group 17. Therefore, there is an advantage that scattering is small after reaching the sea floor (FIG. 10A).

Next, a method in which a large number of blocks 20 are suspended and carried on the raft 19, and the suspension wires 21 are cut and dropped is as follows.
Since there is no need for lifting and the buoyancy of the block itself acts, the raft 19 has only to compensate for the lack of buoyancy of the block with the floating body 22 (FIGS. 10B and 10C).

The block 2 is placed in the hull of the block ship 23.
The method of loading 4 and sinking to the seabed with the block 24 loaded on the block ship 23 does not cause scattering when dropping the block 24, it is easy to drop into the planned sea area, and the outer shape of the block ship is appropriately adjusted. By designing, it is easy to connect and sediment each block ship 23, and it is possible to easily construct a fish reef mountain range having a predetermined shape (FIG. 10).
(D)).

This is because the relationship between the width and the height of the fish reef significantly changes depending on the input environment. The following equation of motion is known as an example of a prediction model in the drop.

[0042]

(Equation 1) σ: Standard deviation (determined for each block)

FIG. 8 shows a calculation result when one point is input using the above equation. The block was tested for elution of various substances, and the results shown in Table 1 were obtained.

[0044]

[Table 1] "Note": "-" does not exist. "Not detected" existed,
Below the lower limit of quantification. The test method is based on the Notification of Environment Agency No. 59 in December 1971.

As described above, it was recognized that there was no elution of harmful substances (at least significantly below the standard).

In the above, the amount of coal ash mainly used in Japan is 7 million tons / year, and its effective use is expected to be 5 million tons / year.
10,000 tons / year will be disposed of (estimated in 1999). The future is expected to increase further, to exceed 10 million tons / year. Since there is a limit in the effective use, an infinite effective use as in the present invention is desired.

On the other hand, the amount of sulfur generated is 2 million tons / year,
Effective utilization is 1,000,000 tons / year for domestic use and 800,000 tons / year for export, so it is expected that blocks will be used for about 200,000 tons / year. On the other hand, in order to construct a fish reef for generating an upwelling in a fish reef in the above-described embodiment, it is possible to calculate that 700,000 to 900,000 tons are required for one mountain reef, so that two rows of mountain ranges can be constructed annually.

In the above, if the outer shell 1a is formed by a block and other industrial waste is provided inside, it is easy to form a block twice as large as the above, though it depends on the thickness of the block. . In addition, the use of exports enables the planning and execution of reef construction projects.

The above description is based on the continental shelf of the Japanese archipelago. Considering this on a global scale, a large reef group or mountain range reef is constructed in an area where spawning and breeding of migratory fish occurs in cooperation with each marine country. It can also be propagated.

[0050]

[Embodiment 2] In the above embodiment, a block molding factory was constructed on land, but if a block molding factory is constructed on a ship as shown in FIG. 2, it can be moved to a fish reef construction area as the block is dropped. . In such a case, the transportation of coal ash and sulfur can be rationalized, but there are restrictions due to offshore work, so selection is made according to the actual situation.

[0051]

[Embodiment 3] An embodiment of the block manufacturing of the present invention will be described. Slag discharged during steelmaking (specific gravity 2.5-3.
5) Pulverized (50 mesh to 100 mesh) slag powder 50% (mass) and sulfur 50% (mass) were uniformly mixed to form a block having a predetermined shape. The compressive strength after cooling and hardening was 20 to 30 N / mm.

The shell of a scallop (specific gravity 1.7 to 2.0)
Was ground (about 50 mesh to 100 mesh), and 50% (mass) of the shell powder and 50% (mass) of sulfur were uniformly mixed to form a block having a predetermined shape. After cooling and hardening, the compressive strength was 20 to 30 N / mm.

Next, 40% (by mass) of coal ash was mixed with cement 6
0% (mass) was uniformly mixed, an appropriate amount of water was added, and the mixture was subjected to vibration pressure to solidify the block. When the compressive strength of this block was measured, it was 20 to 30 N / mm.

In the above embodiment, since slag, shell or coal ash was used alone, the specific gravity was 2.5 to 3.5, 1.7 to 2.
However, the specific gravity of the block can be arbitrarily selected between 3.0 and 2.0 by appropriately mixing and using the slag and shells or coal ash. ,
Blocks of the required specific gravity can be injected into the required parts of the reef.

[0055]

According to the present invention, it is possible to easily and efficiently construct a fish reef mountain range or a general fish reef for generating an upwelling in a predetermined sea area by effectively utilizing coal ash and other wastes and by-products. effective. Further, since the block of the present invention is formed by solidifying coal ash or the like with sulfur, there is no risk of harmful substances being eluted, and the strength is high, so that the block can maintain a predetermined shape for a long time.

In particular, the fish reef for generating the upwelling flow has an effect of efficiently constructing a fish reef mountain range having a predetermined shape and height by input management and data management.
