Description

Marine waste plastic collection and solid fuel manufacturing system ship

The present invention relates to a ship equipped with a manufacturing system that collects marine waste plastics and recycles them to manufacture solid fuel. After collecting marine waste such as waste plastics, the collected marine wastes are desalted and manufactured into pellet solid fuel for disposal. It relates to a marine waste plastic collection and solid fuel manufacturing system ship equipped with a system that can

Currently, the oceans of the five oceans are polluted with a lot of marine debris, of which plastic waste accounts for the largest proportion. According to various surveys and reports, tens of millions of tons of waste plastic waste are floating in the oceans of the five oceans, forming a huge island, and the amount is increasing every year. And among many marine debris, plastic-type garbage that does not decompose for a long time is microplastic broken into fine particles, which remains in the seawater, threatens the survival of fish and shellfish, and is absorbed into their body, causing secondary environmental pollution. .

According to various surveys and research reports, several million tons of plastic debris in the vast five oceans including the Pacific Ocean forms a kind of huge island, and it is expected that the size will increase several times over time, and almost all of it is waste plastic. Non-biodegradable marine debris made of plastics does not stop floating in the ocean, and small-sized microplastics actually have an adverse effect on the marine ecosystem.

However, the treatment of marine waste is limited to processing waste such as plastic waste that has been pushed to the coast or collecting waste floating in nets by mobilizing ships, so there is a limit to handling the large amount of marine waste that is increasing every year. Recognizing the seriousness of marine debris, active research on the collection and treatment of marine debris is being conducted.

As mentioned above, waste plastics, the main marine debris floating in the sea, take more than 500 years to decompose alone, and now they are microplastics that are broken into fine pieces and mixed into seawater, causing serious problems such as being mistaken for food by fish and shellfish. Disposal of marine debris, such as causing side effects, has become a very urgent issue that directly impacts human life and safety.

As a result, research and efforts are being made to reduce the amount of plastic used, and many efforts are being made to collect marine debris. Transport and disposal are also experiencing many technical and economic difficulties in the collection and treatment of marine debris due to the economic cost of long-distance movement from the sea to the land. .

Hereinafter, the prior art related to the treatment of marine debris will be looked at through references.

in reference 1; The floating waste collection device on the water surface has an opening through which the floating wastes floating on the surface of the water are introduced, and the floating waste is collected, the floating body installed in the meshes on both sides of the opening, and the floating body is connected to the opening direction of the mesh There is disclosed a floating waste collection device on the water surface having a collecting means connected to a towing rope mounted on a ship by guiding and collecting the floating waste as a guide.

in reference 2; A self-navigating vessel is adopted as a vessel with self-navigation capability to regularly collect marine waste generated between islands, and it is based on a carriageway that moves between islands. A marine mobile complex processing system composed of a system suitable for the limited size and stable management of the future is disclosed.

in reference 3; By collecting marine garbage floating in the sea while operating the sea and allowing it to be crushed, extruded, and incinerated on the fly, the collected garbage is incinerated directly within the incinerator without the need to transport it to land and incinerate it. A barge for marine waste treatment that reduces the volume of waste by crushing and incinerating marine waste and incinerating a large amount of waste to create a clean sea environment at a low cost through marine cleaning, treatment of polluted waste and recycling of resources This is disclosed.

References 4 and 5; By providing a marine waste resource-processing vessel including a ship load control device, the cost of land transport required for the treatment of marine waste accumulated in the sea is reduced, and since it is processed by the ship according to the present invention at sea, the transport process A marine waste recycling treatment vessel is disclosed to provide an effect that can fundamentally block environmental problems occurring in

in reference 6; A collection device including a hook to collect the floating garbage, a cylinder device connected to the ship and the cover frame to rotate one side of the collection device, a cutting device for cutting the floating garbage introduced along the conveyor, and the cutting device Disclosed is a floating garbage collection and processing vessel comprising a sorting conveyor for transported floating garbage and a treatment device for processing the sorted floating garbage by type so that floating garbage can be collected and treated at sea.

in reference 7; It is a marine waste vessel applied to a ship by mimicking the shape of a beak that can be stretched and wide to easily catch a bird such as a pelican. Disclosed is a marine waste treatment vessel that can collect and treat marine debris by using a material that is stretchable as if it is stretched.

in reference 8; The marine waste collection structure includes a body for accommodating the waste having a passage through which the waste floating on the sea level passes, a blocking part provided on the body to prevent movement of the waste accommodated in the body, and the waste in front of the blocking part There is disclosed a marine waste collection structure comprising a transport unit for transporting the inside of the body.

in reference 9; A Basin is open at its two ends and comprises a plurality of successive sections from the bow of the ship to the stern, each provided with at least one pick-up device, the pick-up devices of each section being different A vessel for recovering marine waste configured to be able to pick up objects of sizes is disclosed.

As seen above, it is estimated that the amount of garbage collected from the sea approaches 300,000 tons per year due to multilateral efforts to cope with serious marine pollution. Although it is highly dependent on the collection of floating garbage on the coast, it is difficult to collect, and it takes a lot of time and money to transport it to land. It is facing two or three difficulties, such as the difficulty of securing a site for long-term storage of waste, as well as the incineration and disposal of the collected waste.

On the other hand, in the case of plastics among marine debris collected from the sea, pretreatment is required to remove toxic hydrogen chloride gas generated during thermal decomposition in advance when converting them into solid fuels. If the detoxification treatment is not performed, hydrogen chloride gas as well as toxic substances such as dioxins are generated when the generated solid fuel is burned.

In this way, when waste plastic is used as fuel, it cannot be used as a fuel in a state where chlorine is not removed, and cannot be used as a fuel because chlorine or dioxin is generated during combustion.

In order to solve this problem, several devices for removing chlorine from waste plastics have been developed. (References 10 and 11) On the other hand, marine debris does not stay at any specific point, but floats in a wide ocean, and its size is large enough to reach the continental United States. The problem of land transport and disposal of waste is also ubiquitous. The marine debris problem is itself a source of environmental pollution and has a significant adverse effect on the survival and breeding culture of fish and shellfish. It is increasing day by day, and attention and research from around the world are focused on solving this problem.

While sailing in the oceans of the five oceans, marine waste plastics are collected and manufactured into the collected pellets, and their processing and manufacturing system is configured on the ship so that the manufactured pellets can be stored. These ships are constructed by building large ships weighing 100,000 tons.

In the hull (A) of the ship, a collection part 10 for collecting waste plastic floating in the sea to the hull, a desalination part 20 for removing the salt of the waste plastic collected in the collection part 10, and a desalination part It consists of a pellet manufacturing line 30 for manufacturing the waste plastic desalted in (20) into pellets, and a transfer part 40 for transporting the manufactured pellets to land.

The above-described ship may be provided with a photovoltaic power generation unit 50 and a wind power generation unit (not shown), which may be implemented with photovoltaic panels, etc., in various places of the hull (A) for efficient operation of various equipment and installations.

The collection part 10 is composed of a clamp crane 1 that collects waste plastic that can be picked up due to its relatively large volume, and a unit 2 that filters the floating waste plastic by sucking it together with seawater. The clamp crane 11 can be implemented to pick up the waste plastic floating on the water surface by installing a plurality of cranes from the bow to the stern of the ship at various positions of the hull (A). The filtering unit 12 together with the tong crane 11 sucks and collects the floating waste plastic of a relatively small size together with seawater.

The filtering unit 12 installs a pump 122 on the inlet 121 side to suck the waste plastic together with seawater, and then passes through the

filters

123, 124, 125, and 126 of the four stages in turn, from large to small lungs. Waste plastics are collected from the ocean by filtering and filtering the plastics. The

filters

123, 124, 125, and 126 of the four steps are filtered sequentially from the largest size to filter the incoming seawater to collect waste plastics, and the last filter may be implemented as a microplastic filter to filter out microplastics.

On the other hand, the seawater filtered through the

filters

123, 124, 125, and 126 of the 4 steps is again filtered through the filtration filter 127 that filters other contaminants, and then discharged into the sea through the water outlet 128.

In this way, the filtering unit 12 composed of the four-

stage filters

123, 124, 125, and 126 sucks and filters seawater on one side and collects waste plastics through this filtering process. It is purified with seawater and discharged into the sea.

The filtering unit 12 composed of the

filters

123, 124, 125, and 126 of the four stages filters and collects waste plastics from large to small sizes through several stages of filtering, and from semi-microplastics invisible to the naked eye to microplastics again in several stages. It can be carried out so that the filtered seawater is discharged back into the sea after filtering through microplastic filtering. The filtering unit 12 is configured to filter and purify ultra-fine plastics, and it goes without saying that various well-known filters and filtration methods can be used for various implementations.

The waste plastics collected in the collection part 10 are made into pellets through the pellet production line 30 after salt is removed from the desalination part 20 .

As already mentioned, toxic hydrogen chloride gas is generated during thermal decomposition of waste plastics collected from the sea, and when solid fuel produced without desalination is burned, not only hydrogen chloride gas but also toxic substances such as dioxins are generated, so the desalination process is difficult. it is absolutely necessary The desalting part 20 is a process of neutralizing until the pH reaches neutral (7), and consists of a warming impregnation process, a primary dehydration process, a room temperature impregnation process, and a secondary dehydration process. Let's look at this in detail.

The desalination part 20 consists of a warming impregnation and an impregnation at room temperature, and a water tank 21 containing a desalting solution for these warm impregnation and room temperature impregnation, and a filter cartridge in which desalination is performed inside the water tank 21. (23,24,25,26) and so on.

The water tank 21 is installed to be rotationally driven by the actuator 22 . The actuator 22 may be installed directly on the bottom surface of the center of the water tank 21 or may be installed to be rotationally driven by a separate power transmission means or the like.

At the bottom of the water tank 21, mounting parts 28 and 28' for inserting and fixing the

filter cartridges

23, 24, 25, 26 are formed through, and discharge covers 281,282, 283, 284 are installed outside the mounting parts 28 and 28'. do. The mounting parts 28 and 28' are formed on the bottom of the water tank 21 by passing through the mounting parts 28 and 28' as many as the dimensions (size) and the number corresponding to the outer diameters of the

filter cartridges

23, 24, 25, 26. And combine the discharge cover (281,282,283,284) to the bottom of the water tank (21). The discharge covers 281,282, 283, 284 enable opening and closing around the pin shaft (symbol omitted).

The

filter cartridges

23, 24, 25, 26 are composed of filters having the same filtering function as the four-

stage filters

123, 124, 125, and 126 of the filtering unit 12, and each size filtered through the four-

stage filters

123, 124, 125, 126 Allows the input of star waste plastics. The waste plastics injected by size into the

filter cartridges

23, 24, 25, and 26 are neutralized through salt washing by the solution of the water tank 21 inside these

filter cartridges

23, 24, 25, and 26. . The

filter cartridges

23, 24, 25, 26 are installed in the mounting parts 28 and 28' as described above, and the waste plastics for each size filtered through the four-

stage filters

123, 124, 125, and 126 of the filtering unit 12 are collected, respectively. put in

As described above, the opening/closing covers 231,241, 251,261 are installed on the upper portions of the

filter cartridges

23, 24, 25, and 26 to which the waste plastics are put, respectively.

Install the support frame 27 in the center of the water tank 21 and connect the opening and closing covers 231,241,251,261 from the support frame 27 with the connecting links 271,271' to open and close the opening and closing covers 231,241,251,261 as shown in the example shown. make it

possible Drain valves

29 and 29 ′ are installed at the bottom of the water tank 21 to discharge the solution in the water tank 21 .

The desalination part 20 of the above configuration performs a desalination operation through a step of a room temperature impregnation operation after a heating impregnation operation. Let's take a look at these.

Install the filter cartridges (23, 24, 25, 26) in the water tank 21, and put the waste plastics for each size filtered through the four-stage filters (123, 124, 125, 126) of the filtering unit 12, respectively, and open and close the cover ( 231,241,251,261).

At this time, for the warming impregnation, a solution (fresh water) of 40° C. of heated water is put into the water tank 21 to the extent that the

filter cartridges

23, 24, 25, and 26 are immersed, and the solution is heated while being impregnated to maintain the temperature of the solution for several hours. A heater can be directly installed in the water tank 21, and as another method, the solution in the water tank 21 is heated by heating by putting a heater into the water tank 21 from the outside or by continuously adding a solution at a certain temperature. It can be done, and the configuration for this is omitted.

At this time, the water tank 21 is rotated slowly to neutralize the waste plastic in the

filter cartridges

23, 24, 25 and 26 by being washed with the solution. The neutralization time is variable depending on the amount of waste plastic input, etc., and since it is a separate invention from the present invention, a detailed description thereof will be omitted. When the neutralization operation is completed, the solution in the water tank 21 is drained from the drain valves 29 and 29', and after draining, the water tank 21 is quickly rotated to remove the waste plastic in the

filter cartridges

23, 24, 25, 26. dehydrate.

The working water that has been drained and dehydrated in the above is discharged into the sea through a purification process.

When the dehydration is completed as described above, a solution of room temperature water (25±5℃) is put into the water tank 21, and at this time, the water tank 21 is rotated slowly to remove the plastic waste in the

filter cartridges

23, 24, 25, 26 by the solution. washed and neutralized. When the neutralization is completed, the water tank 21 is rapidly rotated to repeat the process of dehydration, thereby performing the desalination operation through the neutralization action.

At this time, it is neutralized by repeating the washing operation of heated water and room temperature water until the salinity ph of the waste plastic reaches neutral (7).

When the neutralization operation is completed as described above, the discharge covers 281,282,283,284 are opened around the pin shaft to discharge and collect the neutralized waste plastic, and the desalination operation is performed again as described above.

In the above, the filter cartridges (23, 24, 25, 26) have a structure in which only the upper part is opened and the lower part is closed. 23,24,25,26) to install and work, or

The filter cartridges (23, 24, 25, 26) have a structure in which both the top and bottom are perforated, and waste plastic is put into the upper part of the filter cartridges (23, 24, 25, 26), and only the desalted waste plastic is used in the filter cartridges (23, 24). ,25,26) may be carried out by a method of discharging from it.

The desalination part 20 of the above configuration performs desalination by repeatedly performing the process of impregnating waste plastics with filtered size in warm water → dehydration → impregnation with room temperature water → dehydration.

The waste plastic desalted in the desalting part 20 is manufactured into pellets through the pellet manufacturing line 30 . The pellet manufacturing line 30 includes a pre-processing unit 3 that pre-treats the waste collected in the collection part 20 through processes such as crushing and sorting, and the waste worked in the pre-processing unit 3 into pellets. It consists of a pellet forming apparatus part (4) to shape|mold.

First, the preprocessor unit 3 includes a primary crusher 31, a vibrating screen 32, a primary magnetic separator 33, a secondary crusher 34, a high-speed dehydrator 35, and a wind separator 36. ) consists of

The pellet forming apparatus unit 4 includes an optical sorter 41, a vibrating screen discharge conveyor 42, a secondary magnetic separator 43, a dewatering grinder 44, a molding machine input screw conveyor 45, a molding machine 46, products. It consists of a cutter (47).

The primary crusher and crusher 31 of the pre-processing unit 3 is; Various plastic products such as waste plastics and PET bottles, and marine waste such as wood and cans are shredded by shredding and crushing, and the crushed waste is crushed into small particles again.

The rubbish crushed and pulverized in the primary crusher/shredder 31 is transferred to the primary magnetic separator 33 through the vibrating screen 32 . The vibrating screen 32 applies vibration to the rubbish crushed and pulverized by the primary crusher/shredder 31 to shake off moisture contained in the waste to dehydrate, and transfer the dehydrated waste to the primary magnetic separator 33 .

The primary magnetic separator 33 applies a magnetic force with a permanent magnet or an electromagnet to sort the metal materials mixed in the garbage by sorting the metal materials mixed in the combustible waste (garbage). These metal materials are mixed and formed in the process Prevent machine failures that may occur, etc.

The secondary crusher/shredder 34 crushes and pulverizes the garbage once more and finer and finer as in the case of the primary crusher/shredder 34 . The high-speed dehydrator 35 removes as much as possible the moisture contained in the garbage that has undergone the first and second crushing, pulverization, magnetic force, and wind screening processes, and also decomposes salt in the dehydration process.

The wind separator 36 separates heavy particles and light particles with a distance from the wind power means according to the difference in specific gravity while compressed air is scattered by the wind power means, and relatively heavy glass, iron, etc. are distributed to the lower part and , relatively light plastics are classified as upper.

In addition, the wind separator 36 physically separates the non-combustible materials contained in the crushed waste by using wind power. This is because, if the non-combustible materials are not separated, the machine may malfunction in the process of mixing and molding.

On the other hand, the waste processed by crushing, pulverization, etc. in the pre-processing unit 3 is transferred to the pellet forming unit 4 through the vibrating screen 5 to prepare pellets in earnest.

The vibrating screen 5 vibrates so that the garbage is transported in an evenly spread state so that the operation in the next pellet forming apparatus 4 is performed smoothly.

The pellet forming device unit 4 includes an optical sorter 41, a vibrating screen discharge conveyor 42, a secondary magnetic separator 43, a dewatering grinder 44, a molding machine input screw conveyor 45, a molding machine 46, a product. Pellets are formed with a cutter (47).

The optical sorter 41 of the pellet forming apparatus unit 4 effectively uses the RGB three-dimensional color space information so that the outer shape of the threshold area set by the determination means is accurately specified so as not to include the determination area, The raw material can be discriminated and sorted according to the threshold region, and metal, non-ferrous metal, glass, wood, and the like are sorted using the optical sorting machine 41 .

The garbage selected by the optical sorting machine 41 is transferred to the secondary magnetic separator 43 through the vibrating screen discharge conveyor 42 to be magnetically sorted, and the remaining moisture and smoke are dehydrated in the dewatering grinder 44 and pellets. The final grinding operation is performed to the optimum particle size suitable for manufacturing. The crushed waste is molded into pellets in a molding machine 46 through a molding machine input screw conveyor 45 and cut to an appropriate size by a product cutter 47 to complete pellet molding.

The pellet forming apparatus 4 can be configured to simultaneously produce pellets in the two molding machines 46 when the amount of work is large by connecting the molding machine input screw 45 to the two molding machines 46 .

Marine garbage collected in the pre-treatment process and pellet forming process is washed and dehydrated, and additional dehydration and drying processes are carried out to remove salts that are embedded or permeated in plastics (vinyl waste, resin waste) and textile waste. It is desirable to crush and pulverize the collected marine debris to a size of at least 7~8cm so that it is advantageous for melting during the pellet forming operation.

In addition, in the manufacturing process of the pellets, the mixing ratio between the waste components according to the properties of marine debris for pellet molding (material characteristics of resin, fiber, wood, etc. and combustibility, etc.) depends on the nature of these wastes and the method of manufacturing solid fuel Since there are various, detailed description of the pellet forming process will be omitted.

The waste mixture, which has been mixed and dried for pellet production, is molded to a certain size through extrusion and molding at a temperature of 110 to 150°C. It contributes to molding stability and reacts with sulfide and hydrogen chloride gas to neutralize it, thereby suppressing the emission of dioxins due to the generation of harmful gases.

In the above, the pre-processing unit 3 and the pellet forming unit 4 composed of continuous sections such as various components, and the pellet manufacturing line 3 comprising the pre-processing unit 3 and the pellet forming unit 4 ), etc., are provided with linkage means so that a plurality of continuous sections can be linked to each other to continuously perform the work.

The present invention, as described above, directly collects marine debris of mainly plastic debris, which is seriously polluting the sea, the home of human and marine life, from the oceans of the five oceans, and regenerates them into pellets with collection and manufactures, By transporting it to land and operating the power plant so that it can be used in smart farm agriculture and various industries, waste plastics that cause serious marine pollution can be collected and treated quickly, efficiently and economically, and ultra-fine plastics can also be filtered and purified. It can also contribute to the restoration of clean and clean seas and the protection of marine resources, for example, by being able to configure the existing devices together.

Although the present invention has been described above so that those skilled in the art can easily and clearly understand, descriptions and illustrations thereof are simplified or omitted for technical elements that are not directly related to the technical features of the present invention.

The present invention seeks to restore the marine ecosystem and recycle resources by providing a ship that is equipped with collection equipment to collect and process marine waste such as waste plastics while operating the five oceans and convert the collected waste plastics into solid fuel. It can be widely used in many industries.
