Description

On-site disposal system and method connected with the treatment of deep-sea mining tailings

The present invention relates to harmful substances contained in residues including manganese nodules, etc. generated in the process of developing deep-sea mineral resources (collecting, lifting, ore dressing). It relates to a system and method that can develop and dispose of treated solids at the site of development in connection with treatment that reduces pollutants such as heavy metals and stabilizes and solidifies them.

The self-sufficiency rate of metal minerals in Korea is only 0.4%. In particular, as economic activity increases, the depletion of domestic and foreign terrestrial mineral resources intensifies, and the demand for development of marine mineral resources such as deep-sea mineral resources is increasing. Competition for sea area investigation, exploration rights, and development rights is intensifying in Korea, and from 1994 to 2020, South Korea secured exclusive exploration rights in 5 blocks (water areas such as the Pacific and Indian Oceans, total area of 115,000 km ² , 1.16 times that of the southern part of the Korean Peninsula) did.

In addition, as the commercial development of deep-sea mineral resources by multinational companies in major advanced countries (eg Lockhed Martin, Nautilus Minerals, etc.) becomes visible, international organizations are setting environmental standards related to this (2022-2023).

In general, the space for developing deep-sea mineral resources is the high seas, so it can be applied to sea areas, and a purification treatment method and system that can respond to international environmental standards is essential.

The purification necessary for the development of deep-sea mineral resources is to collect minerals that exist in the deep seabed in the seas far from Korea, such as the Pacific and Indian Oceans, lift them to the sea level, and then recover only useful minerals from mining vessels. Ore dressing), the remaining materials (slurry state in which tens to 100 um of fine solids and waste fluid are mixed) are treated and disposed of with minimal impact on the environment at the site.

Techniques directly or indirectly related to deep-sea mining remnants remediation mainly use techniques used for onshore mining, sediment or soil remediation. Treatment system) is composed of several unit treatment processes, and infrastructure such as tap water and electricity is required, and the size of each unit unit is about several m to several tens of m. Therefore, considerable space is required for installation and operation.

However, unlike land, sea areas have limited infrastructure and space, so land-based technologies cannot be implemented in sea areas. In particular, since the sea area is an environment where living things live together, a system that can be disposed of in the sea area after processing the mining remnants of the deep sea floor to be suitable for the marine environment should be constructed.

In describing the present invention, the terms or words used in the present specification and claims are based on the principle that the inventor can appropriately define the concept of the term in order to best describe his or her invention. It should be interpreted as meaning and concept consistent with the technical idea of

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

The system of the present invention can be built on a mining vessel (1) for developing mineral resources in the deep sea, and the sludge-form deep sea mining residues (a) generated after the recovery of mineral resources are treated in a form suitable for the marine environment. Afterwards, it is characterized in that it is configured to be disposed of in the sea area of the mining site.

Referring to FIG. 1, the system of the present invention includes a treatment tank 10 in which the deep-sea mining residues (a) separated in the resource recovery process are introduced and aggregated and discharged, and the aggregated in the treatment tank 10 The first transfer conveyor 20 for transferring the treated product until the time when the treated product in the state proceeds to solidification, and the second transferring to dispose of the treated solid (c) solidified in the first transfer conveyor 20 to the on-site sea area It includes a transfer conveyor (30).

In the treatment tank 10, the deep-sea mining residue (a) and the stabilizer (b) in the form of a slurry are introduced and mixed, respectively, and the residue (a) is stabilized and solidified by the flocculation reaction of the stabilizer (b), It is to be discharged as a processed product in an agglomerated state having a certain size.

As shown in FIG. 2 , the treatment tank 10 may include a stirring drum 100 , a transfer screw 110 , and an end drum 120 .

First, the stirring drum 100 has an inner space 101, and at one end communicates with the inner space 101 and the first inlet 102 through which the deep-sea mining residue (a) flows and the stabilizer (b) A second inlet 103 through which is introduced may be provided, and an outlet 104 communicating with the inner space 101 may be provided at the other end.

Although not shown in the drawing, the first inlet 102 may be connected to a first storage hopper accommodating the deep-sea mining remnants (a) separated during the mineral resource recovery process, and the second inlet 103 is a stabilizer. It can be connected to the second storage hopper accommodating (b).

The stirring drum 100 is installed along a predetermined interval in the inner space 101 and communicates with the second inlet 103 and further includes a plurality of injection nozzles for spraying the stabilizer (b), It allows the fire (b) to be mixed with the deep-sea mining residue (a) more efficiently.

The transfer screw 110 is installed to be rotatable in the transverse direction from the center of the inner space 101 of the stirring drum 100, and is introduced through the first inlet 102 and the second inlet 103, respectively. While stirring the deep-sea mining residues (a) and the stabilizer (b), the mixture is transferred to the outlet 104 formed at the other end of the stirring drum 100 .

Here, the stabilizing agent (b) induces agglomeration between particles of the sludge-form deep-sea mining residue (a) and solidifies it, thereby reducing the mobility of pollutants such as harmful heavy metals. Among various flocculants used in the soil environment field, Since a suitable one can be selected, a detailed description thereof will be omitted.

The agglomeration drum 120 receives the mixture discharged from the outlet 104 of the stirring drum 100, and aggregates the introduced mixture into a shape of a predetermined size so as to be discharged as a processed product.

As an example, the inlet drum 120 has an inlet pipe 121 having an open upper portion to communicate with the outlet 104 and a discharge hole 125 formed on the lower outer periphery, as shown in FIG. 2 , and the Located inside the inlet pipe 121 and provided with an opening 123 at the upper portion, the mixture introduced through the inlet pipe 121 is accommodated therein, and both sides are provided with pins 124 on the inner periphery of the inlet pipe 121, respectively. ) coupled and selectively rotated inside the inlet pipe 121 so that the opening 123 includes a formwork 122 facing the discharge hole 125 .

That is, the mixture sequentially discharged through the outlet 104 of the stirring drum 100 is introduced into the form 122 while being introduced into the inlet pipe 121, and is fed into the form 122 for a certain period of time. As the input mixture is gradually stacked inside the mold 122 , agglomeration proceeds in a form corresponding to the internal shape of the mold 122 .

When the mixture is aggregated in the form of a certain size in the form 122 in this way, the form 122 is rotated inside the inlet pipe 121 so that the opening 123 of the form 122 is formed through the discharge hole of the inlet pipe 121 ( 125), the processed product in the aggregated state can be discharged from the inside of the mold 122 to the outside.

As such, in the system of the present invention, the size of the group can be adjusted by appropriately adjusting and selecting the inner space and shape of the above-described form 122 . For example, the processed product in the agglomerated state may have a ball or block shape, and a mold 122 having an internal space and shape corresponding thereto may be selectively mounted inside the inlet pipe 121 .

In the first transfer conveyor 20, the processed product in the aggregated state discharged from the treatment tank 10 is placed there, and the processed product in the aggregated state is transported for a predetermined time to solidify the processed product in the aggregated state. and discharged as treated solid (c).

That is, in the case of a treated product having a certain size by mixing the stabilizer (b), it should proceed in a solidified state in which liquid or contaminants do not flow out. The processed product in the aggregated state is transferred, but sufficient time is allowed until the processed product in the aggregated state is solidified in the first transfer conveyor 20 .

Here, the transfer time by the first transfer conveyor 20 may be appropriately set in proportion to the size of the aggregated state processed product. For example, in the case of a processed product having a processing time until solidification of 30 minutes, the transfer time before disposal may be set to 45 minutes in consideration of a safety factor of 1.5.

However, in setting the transfer time of the first transfer conveyor 20, if the operating speed of the first transfer conveyor 20 is adjusted, the processed products in the aggregated state processed and discharged from the treatment tank 10 may be stagnant. Therefore, it is preferable to avoid this, and to adjust the transfer time through the distance and arrangement structure of the first transfer conveyor 20 .

In this case, it is natural that the distance and arrangement structure of the first transfer conveyor 20 may be changed to suit the signage area and field conditions of the mining vessel 1 . For example, the first transport conveyor 20 may be configured to have one or more turning sections around the treatment tank 10 in consideration of the limited signage situation of the mining vessel 1 as shown in FIG. 4 . And, in the case of the moving direction, it may be configured to be changeable to the left, right, or up or down.

The first transfer conveyor 20 separates and discharges waste liquid containing liquid and contaminants generated in the process of transferring the treated product, and prevents marine pollution from occurring as the waste liquid is disposed of together into the sea. means may be included.

For example, the separation means forms a plurality of through-holes 210 along the conveyor belt 200 as shown in FIG. 4A to remove the waste liquid discharged from the processed products in the process of transferring the processed products in the aggregated state to the first To be separated and discharged from the transfer conveyor (20).

As another example, the separation means forms a downward gradient from the center of the conveyor belt 200 toward the outside as shown in FIG. 4b to remove the waste liquid discharged from the processed products in the process of transferring the processed products in the aggregated state. By guiding to the outside of the conveyor belt 200, the waste liquid can be separated and discharged.

At this time, it is preferable to install a catching net on the conveyor belt 200 so that only the waste liquid can flow down while preventing the processed products in the set-up state from rolling to the outside.

As another example, the separation means constitutes a plurality of unit belts 201 of the conveyor belt 200 as shown in FIG. 4c , and forms a space between the unit belts 201 so that the processed products in the aggregated state are transported. In the process, the waste liquid discharged from the treatment product is allowed to fall into the separation space 202 formed between the unit belts 201 so that the waste liquid can be separated and discharged.

And although not shown in the drawing, the first transfer conveyor 20 may further include a drain line for collecting the waste liquid separated and discharged from the separation means and returning the collected waste liquid to the selected purification device.

Here, the drain line may be installed on the lower portion or both sides spaced apart from the conveyor belt 200, but the present invention is not limited thereto, and the arrangement and collection structure may be different depending on the embodiment of the separation means described above. .

The second transfer conveyor 30 is installed so that one end is connected to the discharge side of the first transfer conveyor 20 and the other end is adjacent to the water surface of the field sea area, and delivered in a solidified state in the first transfer conveyor 20 Dispose of the treated solids (c) to the on-site waters.

As shown in FIG. 1 , the second transfer conveyor 30 has a certain inclination because it is arranged to be located at the sea level of the sea area in the mining vessel 1, and by forming the inclination of the second transfer conveyor 30 gently It is possible to prevent the processed solid material (c) being placed on the second transfer conveyor 30 and being transferred from rolling down due to an abrupt inclination.

As another example, the second transfer conveyor 30 adopts an escalator structure that selectively forms step-shaped steps according to the rotational direction as shown in FIG. Ensure that the treated solid (c) can be transported stably, such as not to roll off before reaching.

The first transfer conveyor 20 and the second transfer conveyor 30 described above are preferably made of a material having waterproof and corrosion resistance in order to prevent damage such as corrosion caused by the marine environment as well as waste liquid.

On the other hand, in the system of the present invention, as shown in Fig. 5a, the upper surface is opened to accommodate a part of the other end side of the second transfer conveyor 30, and an inlet 401 is formed in the center of the bottom surface so that the sea level of the field sea level is An accommodating box 400 that allows the other end of the exposed and accommodated second transfer conveyor 30 to face the sea level through the inlet 401, and the accommodating box 400 is coupled to the outer surface of the accommodating box 400 to place the accommodating box 400 at sea level It may further include an anti-disturbance unit 40 including one or more buoyancy spheres 410 to float.

For example, the anti-jamming unit 40 may have a buoyancy sphere 410 installed at a suitable position so that the bottom surface of the accommodation box 400 is in a position in contact with the sea level.

That is, in disposing of the treated solid (c) to the on-site sea area through the second transfer conveyor 30, while limiting the disposal location of the treated solid (c) to the inlet 401 space, the treated solid (c) The accommodating box 400 can limit the disturbance of the sea level and foam that may occur in the process of falling to the sea level, thereby minimizing the factors affecting the marine environment to prevent marine pollution. do.

In particular, the disturbance prevention unit 40 adjusts the installation position of the buoyancy sphere 410 as shown in FIG. 5b so that the lower part of the accommodation box 400 is configured to be submerged in water from the sea level. Bar, in this case, considering that it is difficult to input the treated solid (c) as water from the sea area flows into the inside of the accommodation box 400 through the inlet 401, the upper portion along the edge of the inlet 401 A protruding edge 402 protruding to the is further provided.

At this time, it is preferable that the protrusion height of the protruding edge 402 is equal to or slightly higher than the sea level, and accordingly, the sea level is exposed through the inlet 401 even when a part of the accommodation box 400 is submerged in water. The input location of the solid (c) can be specified.

In this embodiment, as the accommodation box 400 is configured to be located in the water, it is possible to prevent diffusion and disturbance in the water as well as at sea level when the treated solid (c) is disposed, thereby affecting the marine environment. elements can be reduced more efficiently.

Meanwhile, the system of the present invention further includes a configuration for collecting and recording the disposal information in the process of disposing the solidified treated solid (c) to the on-site sea area so that it can be managed.

Specifically, the system of the present invention is mounted on the other end of the second transfer conveyor 30 as shown in FIG. 6 and collects location information and time information for the field sea area where the treated solid (c) is disposed. It may include a unit 50 and a metering unit 60 for measuring and calculating the total amount of the treated solids c disposed of for a predetermined time through the second transfer conveyor 30 .

Here, the information collection unit 50 may be a differential global positioning system (DGPS) module, and the metering unit 70 may be a digital weighing sensor including a load cell or the like.

Record data stored in the database unit 70 can be monitored in the field through the manager terminal 80 installed with a graphical user interface (GUI), and transmitted to and reported to a related monitoring organization, It can also be used as basic data for environmental management.

Hereinafter, the method of the present invention will be described with reference to FIG. 7 .
