Description

Cleaning, cooling and snow removal systems for facilities using oxygen water

[0001] This application claims priority to Korean Patent Application No. 10-2023-0141576, filed October 20, 2023, the entire disclosure of which is incorporated herein by reference.

[0002] The present invention relates to a washing, cooling and snow removal system for a facility, and more particularly, to a washing, cooling and snow removal system for a facility using oxygen water having a structure capable of spraying a washing liquid or snow removal liquid onto a solar panel after water treatment.

[0003] In general, closed water bodies such as rivers, ponds, lakes, dams, and reservoirs, where water flow is slow and stagnant, have a continuous inflow of surface sewage, domestic wastewater, factory and agricultural and livestock wastewater, which increases the concentration of pollutants in the water.

[0004] Nutrients, including nitrogen compounds and phosphates among pollutants, promote the growth and proliferation of microorganisms that decompose organic matter, thus causing eutrophication in freshwater.

[0005] Eutrophication refers to the phenomenon of excessive algal blooms in freshwater caused by the decomposition of organic matter by microorganisms, leading to increased levels of nutrients such as nitrogen and phosphorus. This eutrophication causes serious damage to the lake ecosystem, including reduced freshwater turbidity, foul odors from decaying waste, and, in severe cases, mass fish deaths. Furthermore, in enclosed waters with little water flow, oxygen is depleted in the lower layers, exacerbating water pollution from the bottom.

[0006] Therefore, in closed waters, it is important to maintain a balance so that the amount of nutrients such as nitrogen and phosphorus contained in the aquatic ecosystem does not exceed its self-purification capacity, and it is also very important to increase the dissolved oxygen in the water as much as possible so that the purification process of sinking organic matter and heavy metals can be carried out smoothly.

[0007] However, despite the increase in sewage treatment facilities on the upstream side, many dams, reservoirs, and lakes in the country are still experiencing a deterioration in water quality due to the inflow of large amounts of pollutants and the formation of dense layers over long periods of fresh water.

[0008] Among the major conventional water quality improvement methods, direct purification methods using physical methods include coagulation and sedimentation, direct sedimentation, filtration, aeration, circulation, water purification, and phosphorus recovery technology, while biological methods include direct oxidation, vegetation purification, microbial preparations, and fixation by enzymes. However, as previously discussed, they have limitations in purifying lakes due to short-term purification and local side effects.

[0009] Advances in science and technology have led to the mass production and use of a wide variety of chemicals, raising environmental pollution caused by synthetic chemicals as a social problem. Water pollution caused by non-biodegradable substances, which are difficult to treat using conventional methods, is particularly serious. The problem with hazardous non-biodegradable pollutants is that they are difficult to treat using conventional physical or biological methods alone.

[0010] In addition to the environmental pollution problem of closed water bodies where water flow is slow and stagnant, water pollution caused by early rainfall is also causing serious environmental problems.

[0011] In areas paved with concrete or asphalt, when it rains, the infiltration and retention functions of rainwater are reduced, and highly polluted substances from the initial rainfall flow into nearby sewers or rivers, adversely affecting the water system.

[0012] Pollution that occurs through unspecified emission routes, such as roads, farmland, and construction sites, is called nonpoint pollution. Fine tire dust accumulated on roads, nitrogen oxides (NOx), which are the main culprit of fine dust, pesticide components remaining in farmland, and dust generated at construction sites are all nonpoint pollutants. These are the main cause of river pollution when they are washed away with rainwater when it rains. The reason why these nonpoint pollutants are a problem is that pollutants generated in unspecified places flow directly into rivers when it rains without any special filtration, so they quickly contaminate water quality. Water pollution is much more serious than other types of pollution because it does not simply make water turbid; it can cause mass fish deaths or destroy habitats for plants and animals, disrupting the ecosystem.

[0013] Recently, interest in non-point source pollution reduction devices such as infiltration facilities, retention facilities, and filtration facilities has been increasing to treat non-point source pollution caused by early rainfall.

[0014] Although infiltration facilities and retention facilities, which are called natural non-point source pollution reduction technologies, are said to have good installation effects, they have the disadvantage of taking up a lot of land. Therefore, filtration facilities called filtration-type non-point source pollution treatment facilities are often installed along with natural non-point source pollution reduction facilities. For example, Korean Patent Publication No. 10-1311903 discloses a non-point source pollution filtration treatment device characterized in that a plurality of fiber unit filters are arranged adjacent to each other and continuously inside a debris collection pipe, and polluted water flows through the debris collection pipe, filtering out pollutants and passing through the drain hole of the debris collection pipe to be discharged outside the sedimentation tank.

[0015] Filtration-type non-point source pollution treatment facilities have the advantage of requiring less land area and faster treatment speed than natural types, but have the disadvantage of requiring maintenance such as regular cleaning and replacement of filter media.

[0016] In addition, existing filters only have the function of filtering out pollutant particles, so they have a weakness in that they cannot decompose harmful substances such as nitrogen oxides (NOx) and sulfur oxides (SOx), which are the main culprits of fine dust, and instead pass them through.

[0017] Rainwater or river water collected in the aforementioned storage facilities can be used as cleaning water for solar panels. For example, Korean Patent No. 10-1213146 discloses a solar panel cleaning and remote control system that cleans and remotely controls solar power modules to improve their power generation efficiency.

[0018] However, conventional solar power generation cleaning systems have vulnerabilities in that they cannot treat organic contaminants or various foreign substances remaining in the cleaning water and instead spray them directly onto the surface of the solar panel (power generation module) through the spray nozzle, which can cause the spray nozzle to become clogged, cause stains on the surface of the solar panel, or cause physical and chemical damage to the surface.

[0019] Additionally, since the washing water contains harmful substances such as nitrogen oxides (NOx) and sulfur oxides (SOx), as well as bacteria such as E. coli, there is a concern that it may cause secondary pollution such as water pollution or soil pollution after being sprayed on solar panels.

[0020] The present invention was created in consideration of the above problems, and its purpose is to provide a washing, cooling and snow removal system for facilities using oxygen water, which can spray cleaner and more powerful water on objects such as solar panels by increasing the dissolved oxygen content of the washing liquid or snow removal liquid.

[0021] Another object of the present invention is to provide a washing, cooling and snow removal system for a facility using oxygen water that can improve the air quality around an area where a washing liquid or snow removal liquid is sprayed and does not cause secondary pollution such as water pollution or soil pollution.

[0022] In order to achieve the above object, the present invention comprises: a storage tank for storing a cleaning solution or a de-icing solution; an oxygen generating unit positioned at one selected from the periphery of the storage tank and the interior of the storage tank to increase the dissolved oxygen content of the cleaning solution or de-icing solution; a pipe installed as an embedded or external type; a pump for transporting the cleaning solution or de-icing solution discharged from the storage tank through the pipe; and a plurality of spray nozzles positioned at a set interval and connected to the pipe to spray the cleaning solution or de-icing solution onto the surface of an object; and when the oxygen generating unit is positioned at the periphery of the storage tank, the oxygen generating unit comprises a first oxygen generating unit configured with an oxygen supplier positioned outside the storage tank for providing oxygen gas and an oxygen bubble generator for atomizing the oxygen gas supplied from the oxygen supplier to generate microbubbles or nanobubbles having an average diameter of 1 micrometer (㎛) or less, and when the oxygen generating unit is positioned inside the storage tank, the oxygen generating unit is injected into the storage tank and generates a mixture of potassium superoxide (KO2), perfluorodecalin (C), and the like. 10 F 18 ), a second oxygen generating unit including an oxygen generating composition composed of sodium percarbonate (2Na2CO3·3H2O2) and hydrogen peroxide (H2O2), wherein the first oxygen generating unit generates fine oxygen bubbles so that the dissolved oxygen content of the washing liquid or snow removal liquid sprayed from the spray nozzle is 10 to 55 ppm, and the second oxygen generating unit generates perfluorodecalin (C 10 F 18 ) is 0.5 to 10 wt% of the total weight of the oxygen generating composition.

[0023] The above facility is a clean road system, and the spray nozzles may be 360-degree floor nozzles arranged at set intervals along the road.

[0024] The above facility is a solar power generation facility having a plurality of solar panels arranged, the object is a solar panel, and the plurality of spray nozzles can be arranged at a set interval adjacent to the plurality of solar panels.

[0025] It may further include a filter disposed at the front end of the storage tank and having a filter disposed inside that can filter raw water.

[0026] The filter may further include a first flow meter disposed at the inlet side of the filter and measuring the flow rate before filtration; a second flow meter disposed at the outlet side of the filter and measuring the flow rate after filtration; and a filter replacement controller that determines the time of filter replacement based on the difference between the measurement values ​​of the first flow meter and the measurement values ​​of the second flow meter.

[0027] The above-mentioned deicing solution may further include 2 to 10 wt% of potassium formate, 2 to 10 wt% of potassium acetate, 0.5 to 2 wt% of urea, 3 to 15 wt% of propylene glycol, 0.01 to 0.02 wt% of potassium hydroxide, 0.2 to 0.5 wt% of sodium metasilicate, and 0.15 to 2.0 wt% of potassium triphosphate.

[0028] Seawater and carbon dioxide (CO2) can be introduced into the above storage tank.

[0029] It may further include a remote control device including a mobile phone or central control device that communicates with a control panel capable of controlling the operation of the above pump.

[0030] The washing, cooling and snow removal system of a facility using oxygen water according to the present invention has the following effects.

[0031] First, by increasing the dissolved oxygen content of the cleaning solution or de-icing solution, the water quality of the cleaning solution or de-icing solution can be improved, and the cleaner water with improved cleaning power can be used for cleaning, cooling, and de-icing of facilities such as clean road systems or solar power plants.

[0032] Second, when oxygen gas is contained in the cleaning solution or deicing solution in the form of microbubbles or nanobubbles, the cleaning power of the target object can be further enhanced by the large amount of hydroxyl radicals (OH-radicals) generated when the bubbles collapse.

[0033] Third, the power generation efficiency of solar panels can be improved by using a cleaning solution or an eco-friendly deicing solution that is clean and has improved cleaning power with simple facilities and low cost for washing, cooling, and deicing solar panels.

[0034] Fourth, applying the present invention can prevent corrosion of solar panels when using eco-friendly de-icing fluids and prevent water and soil contamination. Furthermore, the microbubbles in the oxygen water effectively break down and remove fine dust and organic contaminants accumulated on the surface of solar panels, thereby improving the surface condition of solar panels and the air quality around power generation facilities.

[0035] Fifth, by introducing seawater and carbon dioxide into the storage tank, converting the oxygen gas into nanobubbles in the oxygen generator, and combining it with electrons (e-) from chlorine, large-scale hydrogen production is possible. The captured carbon dioxide can then be supplied to factories and other facilities, effectively reducing carbon dioxide emissions and contributing to carbon neutrality.

[0044] The storage tank (100) has an internal space capable of containing a cleaning solution or snow removal solution for surface cleaning or snow removal of an object installed in the facility. Here, the facility may be a variety of facilities requiring cleaning, cooling, and snow removal. Preferably, the facility may be a solar power generation facility. In this case, the cleaning, cooling, and snow removal functions are performed on a plurality of solar panels (1, power generation modules) installed in the solar power generation facility as objects. Hereinafter, the configuration of the invention will be described in detail with a focus on an embodiment in which the facility is a solar power generation facility.

[0045] The main component of the above cleaning solution or deicing solution may be rainwater secured through rainwater storage tanks in subway stations, groundwater, spring water, river water procured from rivers connected to various non-point pollution sources, tap water used for household, industrial, or agricultural purposes, or reclaimed water.

[0046] The upper part of the storage tank (100) is provided with an inlet for injecting water and a cover, and the lower part is provided with a discharge part for discharging the stored water to the outside.

[0047] It is preferable that the above-mentioned deicing solution does not contain a chloride-based component to prevent corrosion of the solar panel (1). Considering this, it is preferable that the above-mentioned deicing solution is an environmentally friendly composition comprising 2 to 10 wt% of potassium formate, 2 to 10 wt% of potassium acetate, 0.5 to 2 wt% of urea, 3 to 15 wt% of propylene glycol, 0.01 to 0.02 wt% of potassium hydroxide, 0.2 to 0.5 wt% of sodium metasilicate, and 0.15 to 2.0 wt% of potassium triphosphate. This technical composition is disclosed in more detail in Korean Patent No. 10-1787963, which the applicant of the present invention previously applied for and was granted a patent for.

[0048] It is preferable that a vertically arranged stirrer (not shown) be provided at the inner center of the storage tank (100). The stirrer has a structure in which a stirring blade is installed below a motor fixed to the upper portion of the storage tank (100). The stirrer can more effectively prevent functional substances or deicing particles remaining in the water stored in the storage tank (100) from settling or the water from freezing by slowly rotating the stirring blade. The installation structure of the stirrer is disclosed in more detail in the registered patent publication No. 10-2073520, which the applicant of the present invention previously applied for and was granted a patent for.

[0049] The first oxygen generating unit (20) is arranged around the storage tank (100) and performs the function of increasing the dissolved oxygen content of the cleaning solution or de-icing solution to be injected (or injected) into the storage tank (100). Preferably, the first oxygen generating unit (20) can generate oxygen so that the dissolved oxygen content of the cleaning solution or de-icing solution injected from the injection nozzle (120) is 10 to 55 ppm.

[0050] As shown in Fig. 2, the first oxygen generating unit (20) includes an oxygen supply unit (20a) that provides oxygen gas, and an oxygen bubble generator (20b) that atomizes the oxygen gas supplied from the oxygen supply unit (20a) to generate fine oxygen bubbles in the cleaning solution or snow removal solution.

[0051] It is preferable that the oxygen bubbles generated from the oxygen bubble generator (20b) are microbubbles or nanobubbles having an average diameter of 1 micrometer (㎛) or less.

[0052] Seawater and carbon dioxide (CO2) can be introduced into the storage tank (100). In this case, the first oxygen generating unit (20) can convert oxygen gas into nanobubbles and combine them with electrons (e-) from chlorine contained in the seawater to produce hydrogen. In this case, the captured carbon dioxide can be supplied to factories and other locations, thereby substantially reducing carbon dioxide emissions and contributing to carbon neutrality.

[0053] The filter (10) is arranged at the front end of the storage tank (100) and has a configuration in which a filter capable of filtering raw water is arranged inside. Preferably, a first flow meter (11) is arranged at the inlet side of the filter (10) to measure the flow rate of raw water before it is filtered. In addition, a second flow meter (12) is arranged at the outlet side of the filter (10) to measure the flow rate after filtering.

[0054] A filter replacement controller (not shown) determines the time for filter replacement based on the difference between the measurement values ​​of the first flow meter (11) and the second flow meter (12). For example, if the measurement value of the second flow meter (12) is half that of the first flow meter (11), the filter replacement controller may determine that the filter of the filter (10) is approximately 50% clogged and output an alarm to notify filter replacement.

[0055] As illustrated in FIG. 3, the washing, cooling and snow removal system of a solar power generation facility according to another embodiment of the present invention includes a second oxygen generating unit (20'), which is an oxygen generating unit that is disposed inside a storage tank (100) and purifies the washing liquid or snow removal liquid by treating it.

[0056] As shown in Fig. 4, the second oxygen generating unit (20') is composed of potassium superoxide (KO2) and perfluorodecalin (C 10 F 18 ), sodium percarbonate (2Na2CO3·3H2O2) and hydrogen peroxide (H2O2). Preferably, the perfluorodecalin (C) is added to make the dissolved oxygen content of the cleaning solution or deicing solution in the storage tank (100) 10 to 55 ppm. 10 F 18 ) may be 0.5 to 10 wt% based on the total weight of the oxygen-generating composition. As with the above-described embodiment, the washing / cooling and snow removal system of the solar power generation facility according to the present embodiment may be operated as a practical solar panel washing and cooling system that uses groundwater or rainwater storage tank water as a washing liquid in the summer, and may be operated as a practical solar panel snow removal and ice removal salt water spray system that removes snow accumulated on the surface of the solar panel (1) by adding a chemical having anti-icing and snow removal functions to the washing liquid in the winter and using it as a snow removal liquid. It is preferable that the snow removal liquid does not contain a chloride-based component in order to prevent corrosion of the solar panel (1). Considering these points, it is preferable that the above-mentioned deicing liquid be an environmentally friendly composition containing 2 to 10 wt% of potassium formate, 2 to 10 wt% of potassium acetate, 0.5 to 2 wt% of urea, 3 to 15 wt% of propylene glycol, 0.01 to 0.02 wt% of potassium hydroxide, 0.2 to 0.5 wt% of sodium metasilicate, and 0.15 to 2.0 wt% of potassium triphosphate.

[0057] As shown in FIGS. 1 and 3, the pump (104) provided in the present invention is connected to the discharge portion of the storage tank (100) through a predetermined pipe and pumps the cleaning solution or snow removal solution discharged from the storage tank (100) at a predetermined flow rate and pressure. It is preferable that at least two pumps (104) be provided, one of which serves as a main pump and the other serves as an auxiliary pump.

[0058] An air supply device (103) is installed on one side of a pipe connected to a storage tank (100) and supplies air to discharge the remaining liquid in the pipe to the outside through a spray nozzle (112). The air supply device (103) may be connected to a separate air compressor, or alternatively, the air supply device (103) itself may be configured as an air compressor.

[0059] The cleaning solution or snow removal solution discharged from the storage tank (100) and pumped by the pump (104) is supplied to the pipe (111) via the main pipe (105).

[0060] A pump station is a facility that surrounds the exterior of a pump (104), a main pipe (105), an air supply device (103), a control panel (106), etc. to protect them. The pump station may be constructed as a house made of a concrete structure, etc., or a container, etc.

[0061] A pipe (111) is installed within a solar power generation facility to transport a cleaning solution or deicing solution pumped by a pump (104) and supply it to a spray nozzle (112). A portion of the pipe (111) may be buried underground within the solar power generation facility. Another portion of the pipe (111) extends above ground around the solar panel (1) and is substantially connected to a spray nozzle (112) installed adjacent to the solar panel (1). Preferably, a plurality of spray nozzles (112) may be assembled at a predetermined interval on a predetermined pipe, and the pipe (111) may be connected to the pipe.

[0062] The control panel (106) controls the operation of the pump (104) to control the flow rate and pressure of the cleaning solution or de-icing solution, and to control on / off, etc. The control panel (106) can be remotely controlled by communicating with a remote control device (107) that is composed of a remote control system including a remote mobile phone (smartphone) (103a) and / or a central control device (103b) which is a computer located in a central control room. The remote control device (107) can perform data communication with the control panel (106) through wired or wireless Internet, various serial communications, etc. Specifically, communication between the remote control device (107) and the control panel (106) can be performed according to at least one communication protocol selected from among, for example, LoRa, CDMA, LTE, Ethernet, CAN, RS422, RS232, and RS485. At least one communication protocol selected from among LoRa, CDMA, LTE, RS422, RS232, and RS485 may be used for communication between the control panel (106), the storage tank (100), the pump (104), the sensor (113), and the electric valve (109).

[0063] The control panel (106) preferably has a metal housing and can be spatially installed within the pump station. The control panel (106) controls the valve box (108), the pump (104) or various control valves within the pump station, the main pipe (105), the operation control for the agitator, and the switching control for manual / automatic operation modes.

[0064] The wireless communication that can be used in the present invention includes various wireless communication standards, including IoT-related communication standards such as Bluetooth, LoRa communication, and NB-IOT, as well as LoRa, CDMA, LTE, and 5G.

[0065] The valve box (108) may be installed externally or embedded in at least one location within the solar power generation facility. The valve box (108) may be arranged one by one for each spray group including a plurality of spray nozzles (120). For example, if the solar panels (1) included in the solar power generation facility are arranged in a substantial matrix, a valve box (108) may be arranged for each row (or column).

[0066] The washing, cooling and snow removal system of a solar power generation facility is equipped with a detection unit (113) that detects the spraying status of the spray nozzle (112), the standby status, the temperature of the solar panel (1), etc., and transmits them to a remote control device (107) that is comprised of a remote control system including a mobile phone (107a) or a central control device (107b) through a control panel (106).

[0067] The detection unit (113) is equipped with at least one detection sensor among a fine dust detection sensor that detects fine dust, a hazardous substance detection sensor that detects at least one selected from sulfur oxides, nitrogen oxides, volatile organic compounds, and radon, and other hazardous substances prescribed by the Ministry of Environment Ordinance, a temperature and humidity detection sensor that detects temperature and humidity, and a rainfall / snowfall sensor that detects the amount of snow or rain. The detection signal output from the detection unit (113) is transmitted to the control panel (106) through the communication card box (114).

[0068] Additionally, a video surveillance camera (116) that enables real-time confirmation of the spraying status, etc., and an information display board (117) composed of an LED or liquid crystal display device that displays the spraying status of the cleaning solution or deicing solution, the concentration of fine dust, and the weather conditions may be placed around the detection unit (113). In addition, a broadcasting device (not shown) equipped with a speaker that outputs voice to guide and control the on-site situation in real time in conjunction with the information display board (117) may be installed on one side of the periphery.

[0069] The information board (118) is an LED board, for example, installed on a designated support or structure around the solar panel (1), and displays phrases such as “solar panel (1) being washed” or “solar panel (1) being snow-removed” to provide convenience for the maintenance of solar power generation facilities.

[0070] The injection nozzle (120) may be at least one selected from a fixed nozzle and a rotary nozzle. A representative rotary nozzle is the "fluid injection system" disclosed in Korean Patent No. 10-2173177, which was previously applied for and patented by the applicant of the present invention.

[0071] A washing, cooling and snow removal system for a solar power plant having the above configuration can be constructed by a construction method including a excavation process, a pipe installation process, and a nozzle installation process.

[0072] In the excavation process, excavation work is performed around the solar panel (1) placement area within a solar power generation facility to form a passage for burying pipes. Here, the solar panel (1) placement area may be a parking lot roof, a factory roof, an empty lot, a forest, a lake, or a fallow field.

[0073] In the pipe installation process, the pipe (111) is installed along the above pipe embedding passage.

[0074] The spray nozzle (120) can be assembled at a predetermined interval on a predetermined pipe. The assembly of the spray nozzle (120) and the pipe can be fixed to a predetermined frame or structure that supports the solar panel (1).

[0075] As described above, the washing, cooling and snow removal system of a solar power generation facility is provided with a first oxygen generating unit (20) or a second oxygen generating unit (20') to increase the dissolved oxygen content of the washing liquid or snow removal liquid injected into the storage tank (100). The water purified in this way is transferred to the spray nozzle (120) via a pipe (111) so that it can be evenly sprayed onto the surface of the solar panel (1).

[0076] The amount of dissolved oxygen increases by the first oxygen generating unit (20) or the second oxygen generating unit (20'), and especially when oxygen gas is contained in the cleaning solution or de-icing solution in the form of microbubbles or nanobubbles, there is a remarkable effect of further increasing the cleaning power on the surface of the solar panel (1) by a large amount of hydroxyl radicals (OH-radicals) generated when the bubbles collapse.

[0077] Although the present invention has been described above with reference to limited embodiments and drawings, the present invention is not limited thereto, and it is obvious that various modifications and variations are possible within the scope of the technical idea of ​​the present invention and the equivalent scope of the patent claims to be described below by a person having ordinary skill in the art to which the present invention pertains.

[0078] By applying the present invention, the power generation efficiency of solar panels can be improved by using a cleanly purified cleaning solution or de-icing solution with simple equipment and low cost for washing, cooling and de-icing solar panels, and further, the air, water quality and soil environment around solar power generation facilities can be efficiently improved.
