Specific details for implementing the invention

[0026] In areas of the sea, rivers, or streams where the flow velocity is low or stagnant, organic substances such as domestic sewage, industrial wastewater, and livestock excrement flow into the aquatic ecosystem. As these substances gradually settle and accumulate over time, the settled byproducts decompose as summer temperatures rise. Consequently, biodiversity is disrupted, and one or a few types of cyanobacteria become dominant and multiply in large quantities, causing the water to turn green.

[0027] Therefore, the most important cause of algal blooms is the increase in the concentration of nutrients such as phosphorus and nitrogen in the water, that is, eutrophication.

[0028] The optimal water temperature for the occurrence of algal blooms is 13 degrees or higher, and the surface water temperature of stagnant water in midsummer rises above 20 degrees.

[0029] As explained above, as summer temperatures rise, organic matter with a high Trophic State Index (TSI) decomposes, resulting in the occurrence of algal blooms.

[0030] Therefore, it follows that if the temperature of the surface water can be lowered, algal blooms can be significantly reduced.

[0031] Therefore, the present invention is a device that removes algae by installing a solar heat absorption plate to cause deep water to rise using only pure solar heat.

[0032] Secondly, a device was developed that uses wind power to upwell deep water on cloudy days when solar heat cannot be absorbed, thereby preventing or significantly reducing the occurrence of algal blooms.

[0033] Third, a device was developed that removes algae by utilizing both solar and wind power simultaneously to cause deep-sea water to upwell.

[0034] The present invention has the advantage of being eco-friendly, achieving high efficiency at low cost while having no impact on the environment.

[0035] The present invention aims to suppress algal blooms occurring in seas, rivers, or streams.

[0036] Solar heat absorption panels are constructed on the water surface.

[0037] A metal cylindrical tube is configured to enable heat transfer to the lower part of the solar heat absorption plate (100).

[0038] An eco-friendly algae bloom suppression device is configured such that the water temperature inside the metal cylindrical tube (200) rises due to the solar heat absorption plate (100), and the deep water with a lower temperature moves to the upper surface of the water due to the upwelling phenomenon caused by the temperature difference between the surface water and the deep water, thereby lowering the temperature of the surface water and preventing the occurrence of algae bloom.

[0039] An upper wind power meter (330) is configured on the upper part of the solar heat absorption plate (100), and a rotating screw (350) is configured inside the metal cylindrical tube (200) in conjunction with it, so that the rotating screw (350) is rotated by the upper wind power meter (330) to bring deep water up to the surface.

[0040] The wind meter is intended to help the upwelling of water by using wind power to rotate the rotating screw (350) at the bottom, whether there is no sun or there is sun.

[0041] A buoyancy plate (130) is configured at the bottom of the solar heat absorption plate (100).

[0042] It is preferable that the material of the solar heat absorption plate (100) and the metal cylindrical tube (200) be composed of aluminum plate, which facilitates heat transfer.

[0043] A bellows-shaped duct-type tube (400) is connected to the lower end of the metal cylindrical tube (200) to absorb the shock caused by the up-and-down movement of the solar heat absorption plate (100) due to waves from the surface water.

[0044] In the drawings and detailed description, a duct-type cylindrical tube (400) connected to a metal cylindrical tube (200), which is an aluminum cylindrical tube, is configured.

[0045] The duct-type cylindrical tube (400) prevents the solar heat absorption plate (100) from being overturned by waves and also serves as a weight to absorb vibrations and prevent shaking.

[0046] A flexible so-called bellows connected to the metal cylindrical tube (200) of the eco-friendly algae bloom suppression device is used as an auxiliary material to absorb shocks caused by the up-and-down movement of the solar heat absorption plate (100) body due to waves in the surface water, thereby maintaining the stability of the solar heat absorption plate (100) and acting as a weight to prevent the solar heat absorption plate (100) from being overturned by wind or waves in the surface water.

[0047] Flexible bellows hoses are suitable as lightweight, flexible, and cost-effective ducted cylindrical tubes.

[0048] The upper part of the metal cylindrical tube (200) is configured with a plurality of water transfer holes (210) so that the upwelled deep water can easily move to the surface.

[0049] A plurality of water transfer holes (210) formed in a metal cylindrical tube (200) below the solar heat absorption plate (100) are configured so that when the solar heat absorption plate (100) shakes due to waves and upwelling water cannot flow to the upper part of the solar heat absorption plate (100), or when solar heat absorption is impossible on a cloudy day without sunlight, the upwelling water can be easily drained by rotating a rotating screw (350) with wind power to upwell deep water.

[0050] The above upper wind power meter (330) is configured by forming a support (310) on the above solar heat absorption plate (100).

[0051] The above solar heat absorption plate (100) is composed of a solar heat absorption paint layer (110) that absorbs solar heat on the upper part of a metal plate (120) and a buoyancy plate (130) on the lower part of the metal plate (120).

[0052] The above buoyancy plate (130) may be constructed by applying a foaming agent to the bottom or attaching styrofoam or block air cushions to float the solar heat absorption plate (100) on the water surface.

[0053] The thickness of the foaming agent applied may vary depending on the size and weight of the solar heat absorption plate (100). Another method is to process and attach a styrofoam or block air cushion to a thickness suitable for the weight of the eco-friendly algae growth suppression device, and then apply an eco-friendly paint to the surface to waterproof it.

[0054] By configuring the foaming agent at the bottom in this way, appropriate buoyancy is created so that the position of the solar heat absorption plate (100) is positioned on the water surface.

[0055] At this time, the depth of the eco-friendly algae growth suppression device is adjusted so that it has appropriate buoyancy to be positioned above the water surface by varying the thickness of the coating according to the weight of the eco-friendly algae growth suppression device based on its size, adjusting the thickness of the styrofoam, or adjusting the amount of block air cushion.

[0056] The reason why it is most desirable for the upper surface of the solar heat absorption plate (100) to be installed 10 to 20 mm below the water surface in the second embodiment is as follows.

[0057] If the solar heat absorption plate (100) is located below the water surface above that level, it is difficult to continuously transfer solar heat to the solar heat absorption plate (100) due to the refraction of light.

[0058] In addition, since the water heated by being located on the water surface flows over the upper part of the solar heat absorption plate (100), it also has the effect of preventing the heat of the solar heat absorption plate (100) from dropping due to the cold water.

[0059] During the time when the summer sun is at its hottest (2-3 pm), the temperature of the metal plate (120) due to solar heat rises to a maximum of 70-80 degrees, taking into account the loss due to light reflection.

[0060] Therefore, the solar heat-absorbing paint layer (110) applied to the upper part of the metal plate (120) absorbs solar heat at an absorption rate of approximately 95% ± 2, so the surface temperature of the metal plate (120) can rise to approximately 70 to 80 degrees or higher.

[0061] Solar heat absorbed from the solar heat absorbing paint layer (110) is transferred to the metal plate (120), and solar heat absorbed is transferred to the metal cylindrical tube (200) through the metal expansion part (122) connected to the metal plate (120) and the metal cylindrical tube (200).

[0062] To transfer heat from the solar heat absorption plate (100), an aluminum tube that facilitates heat transfer is used through a metal plate (120) and a metal cylindrical tube (200) connected to the bottom.

[0063] In addition, it is configured to raise the temperature of the water inside the metal cylindrical tube (200) using the solar heat.

[0064] The heat transferred to the metal cylindrical tube (200) heats the water inside the metal cylindrical tube (200), and thus upwelling occurs due to the temperature difference between the upper and lower parts of the water inside the metal cylindrical tube (200).

[0065] Heat absorbed from the top of the solar heat absorption plate travels through the cylindrical tube and is transferred from top to bottom; consequently, the cold water at the bottom of the tube is heated and undergoes upwelling. The warm water at the top mixes with the water rising from the bottom, causing its temperature to drop and push out in all directions, circulating downwards (convection).

[0066] Due to upwelling, deep water with a low temperature at the bottom of rivers, seas, or streams rises to the surface and lowers the temperature of the surface water to 13 degrees or lower, which inhibits the occurrence of algal blooms.

[0067] For the solar heat absorption paint layer (110), a special paint is used to maximize the solar heat absorption rate.

[0068] Special paints are mainly used in flat-plate solar collectors and exhibit an absorption rate of about 95% ± 2 with a deposition coating of Cu-DHP (copper oxide).

[0069] The above solar heat absorption plate (100) is configured with a fixed anchor on the bottom of the water surface so that the solar heat absorption plate (100) is positioned on the water surface or below the water surface.

[0070] To fix the body of the eco-friendly algae growth suppression device to the bottom of a river or sea, a fixing anchor (500) and a rope (600) are used.

[0071] The rope (600) connected to the body of the eco-friendly algae growth suppression device is made about three times longer than the depth of the river, sea, or stream to allow the absorption plate body to move left and right.

[0072] In an embodiment of the present invention, the material of the metal plate (120) that absorbs solar heat is composed of an aluminum plate that facilitates heat transfer.

[0073] The metal cylindrical tube (200) forms a water transfer hole (210) in a portion adjacent to the solar heat absorption plate.

[0074] The lower deep water moves to the upper part and the upper hole (115, 125, 135) is formed to allow the rotation axis to be inserted.

[0075] Drawing 3a shows a solar heat-absorbing paint layer (110) obtained by applying solar heat-absorbing paint to a metal plate (120).

[0076] The description of the foaming agent configured on the lower part of the metal plate (120) is as follows.

[0077] Foaming is defined as the process of creating a foamed body by acting a foaming agent on a plastic or rubber structure to generate gas and form cells under a certain temperature, pressure, and time.

[0078] This foaming is intended for the purpose of lightweighting, cushioning, buoyancy, absorbency, decorative properties, tactile properties, cost reduction, and dimensional stability of the product. The main materials for foaming include PVC, PE, PP, Rubber, EVA, PS, PU, ​​and TPR, but it is mainly used on PVC, Rubber, and EVA.

[0079] Blowing agents are broadly classified into physical blowing agents and chemical blowing agents, and chemical blowing agents are further classified into inorganic chemical blowing agents and organic chemical blowing agents.

[0080] Representative examples of physical blowing agents include butane and pentane, which are used in products such as EPS and EPP. Chemical blowing agents include inorganic blowing agents such as sodium bicarbonate (NaHCO3) and organic blowing agents such as ADAC, OBSH, and TSH; however, most chemical blowing agents are organic blowing agents, and inorganic blowing agents account for only 2-3% of total demand. Among organic blowing agents, the most widely used general-purpose product is the ADAC-based type, which has self-extinguishing properties and is non-toxic; in 1962, its incorporation at a concentration of 45 ppm was permitted as a heat-reducing agent and bleaching agent for wheat flour.

[0081] Azodicarbonamide (ADAC) is generally manufactured by reacting urea with hydrazine hydrate to produce the intermediate HDCA (Hydrazodicarbonamide), which is then oxidized using oxidizing agents such as chlorine gas or hydrogen peroxide. DPT (N,N'-Dinitrosopentamethylene tetramine) is a highly economical product with the highest gas content per unit of blowing agent, and it is primarily used for rubber applications. Its decomposition temperature is 200–250°C; it is generally used in combination with urea-based additives, and mixtures of DPT and urea-based additives are manufactured to enhance handling and loading stability. EVA foam utilizes a DPT / urea-based composite blowing agent, where the urea-based additive lowers the decomposition temperature to decompose DPT, and the resulting heat from the decomposition then accelerates the decomposition of Azodicarbonamide (ADAC).

[0082] OBSH (P,P'-oxybis(benzene sulfonyl hydrazide)) has excellent loading stability like AC, but since it does not disperse well in polymers, its dispersibility is improved by surface treatment with a small amount of mineral oil. It is used in applications such as PVC wallpaper, CR wetsuits, and EPDM W / S. TSH (P-toluene sulfonyl hydrazide) first dissolves at 170°C and exhibits initial decomposition, followed by rapid decomposition at 145–150°C, which is a different characteristic from OBSH and DPT foaming agents, which dissolve and then rapidly decompose.

[0083] Unlike AC and DPT, PTSS (P-toluene sulfonyl semicarbazide) is a high-temperature decomposition foaming agent with a decomposition temperature approximately 20 to 30 degrees higher. It is used in calendering processes where there is a risk of initial foaming during Plastisol processing, where whiteness is required. In particular, it has the advantage of being usable under controlled conditions during rigid extrusion foam processing (foamed extrusion pipes, plates, sheets, windows, polystyrene, and Enpla). The gas composition after decomposition is estimated to be N2 55%, CO2 37%, CO 2%, and NH3 3%.

[0084] Domestic foaming agent suppliers are divided between two companies, Kumyang and Dongjin Kasung. It is known to be one of the items with over 90% localization achieved, supplying the majority of domestic demand. Imports are mainly specialty foaming agents from Japan, such as Eiwa and Toyo Hydrazine, amounting to less than 10 tons per month. Types of foaming agents include ADAC, which accounts for 60% of total demand, as well as TSH, OBSH, PTSS, and DPT.

[0085] The main demand comes from its use in foamed products made of PVC, EVA, Rubber, PE, PP, PS, ABS, etc., specifically in processed PVC products (flooring, wallpaper, leather, etc.).

[0086] EVA is used in shoe soles, industrial materials, and rubber (EPDM, NBR, CR, SBR, NB) used in anti-slip tires and automotive parts. JTR grade (Kumyang) and DX73 (Dongjin Kasei) are mainly used for EVA and rubber.

[0087] PE is primarily used for automotive applications (ceiling materials, insulation, packaging, industrial materials), etc., by companies such as Youngbo Chemical and Tongil Industrial.

[0088] The main raw materials of the foaming agent are mainly Hydrazine Hydrate and industrial urea for the ADAC system.

[0089] The DPT system mainly uses hexamine, and in addition to being a foaming agent, hexamine is used as a rubber vulcanization accelerator, a raw material for pharmaceuticals, and is also used in the manufacture of explosives.
