Description

Therefore, the independent power generation system can be used for various purposes, such as building an independent energy production facility in remote areas such as Africa, or building an emergency energy supply facility for disaster or military use. In order to increase the energy utilization efficiency of the independent power generation system, a structure that can efficiently store solar power generation modules and an energy storage system (ESS) that can efficiently store and manage the generated power is required.

In remote areas such as Africa, developing countries or rural areas, it may be difficult to directly link the existing power grid. Therefore, it may be effective to install an off-grid power generation system capable of independently generating power. A standalone power generation system is a system that can generate and store power using sustainable energy such as sunlight or solar heat. In order to secure the efficiency and sufficient power generation capacity of the stand-alone power generation system, it may be important to collect and utilize solar energy to the maximum. To this end, it is possible to increase the energy that can be obtained by increasing the number of solar panels. However, in the process of exporting or transferring the independent power generation system, each module and component must be stored in an export-type container, and there may be a limit on the number of solar panels that can be stored due to a limitation of space inside the container. Accordingly, in order to store as many solar panels as possible in a limited space, a structure capable of efficiently storing solar panels is required. On the other hand, after packaging the stand-alone power generation system in a container and transferring it to a corresponding area, an installation process such as deploying the stored solar panel is required. In order to reduce installation cost and installation manpower, an efficient deployment structure is required. In addition, structural stability should be secured while installing the solar panel at an appropriate angle. On the other hand, in an area where an independent power generation system needs to be installed, it may be difficult to directly supply purified water and hot water essential for life as well as a power grid. For example, in remote areas such as Africa or in military areas, it may be difficult to directly supply purified water and hot water by connecting existing water networks. As a method of purifying water, distillation, reverse osmosis, deionization, or filter purification may be used. In remote areas such as Africa, given that the medical system is not developed, a distilled water purification method that can completely remove bacteria, chlorine, mercury and nitrate, and even viruses and microorganisms may be the most suitable. Solar heat can be used to distill water, and hot water can be produced using collected solar heat. In addition, by connecting the independent power generation system and the water purification system to each other, it is possible to construct a module combination package system capable of producing both purified water and hot water at the same time while generating power using solar heat or the like. A modular package system capable of producing all of power, purified water, and hot water using solar heat or the like can be stored in one container and exported and transported. When a modular package system is installed in remote areas such as Africa, it can be efficient in that it can produce all of the electricity, purified water, and hot water required for living in one package system.

1 is a schematic diagram of a module combination package system according to an exemplary embodiment. 2 is a block diagram of a module combination package system according to an exemplary embodiment.

1 and 2, a module combination package system 1 according to an embodiment includes a solar power generation system 11, an energy storage system 12, a purified water-hot water system 13, and a solar thermal composite module. (14) and a waste heat recovery unit 15 may be included.

The module-combined package system 1 is a single package system, and may be a system that independently produces and stores electric power, purified water, and hot water using sunlight and solar heat. The modular combination package system 1 can be supplied to areas where electric power, purified water, and hot water are required, such as Africa, developing countries or military areas. The module combination type package system 1 may be stored in one container C so that export and transport are conveniently performed. The solar power generation system 11 may generate electric power using sunlight. The energy storage system 12 may store power produced by the solar power generation system 11. The energy storage system 12 may be disposed under the container C. According to this arrangement, the storage efficiency of the energy storage system 12 can be increased while maintaining the center of gravity of the container C. The purified water-hot water system 13 may produce purified water and hot water using solar heat. The solar thermal composite module 14 may generate electric power using sunlight and solar heat, and supply the collected solar heat to the purified water-hot water system 13 to assist in the production of electric power, purified water, and hot water. The waste heat recovery unit 15 supplies waste heat generated from the energy storage system 12 to the purified water-hot water system 13 to maximize the use of wasted heat. According to such a configuration, it is possible to produce and supply all of power, purified water and hot water with one module combination package system 1, and thus, it is possible to provide an independent and comprehensive solution in remote areas such as Africa.

Referring to FIG. 3, the purified water-hot water system 13 according to an embodiment may produce and supply purified water and hot water using solar heat. When the purified water-hot water system 13 is installed in a remote area such as Africa, purified water and hot water required for living may be simultaneously produced by using natural energy such as solar heat. In remote areas, such as Africa, where health and medical facilities are scarce, it can be particularly important to completely remove contaminants from raw water to make drinking water available. To this end, the purified water-hot water system 13 may purify raw water by distillation. Using distilled water, arsenic, bacteria, cadmium, calcium, chloride, chlorine, copper, cryptosporidium, detergents, fluorides, lead, magnesium, mercury, nitrates, minerals, pesticides, phosphates, radon, precipitates, sodium, Contaminants including sorbatiazole and viruses can be completely removed from raw water. Solar heat can be used for distillation water purification. In addition, hot water can be produced by heating raw water with solar heat. The purified water-hot water system 13 efficiently circulates and uses heat, thereby increasing the productivity of purified water and hot water. The purified water-hot water system 13 may include a structure in which hot water vapor is condensed with cold raw water in a raw water tank, and heat is supplied from the hot water vapor to preheat raw water.

The purified water-hot water system 13 according to an embodiment includes a raw water tank 131, an evaporation chamber 132, a condensation part 133, a collection chamber 134, a water purification tank 135, a raw water supply line 136, A raw water filter unit 137, a hot water tank 138, a solar heat collector 1391, a heat exchange circulation line 1392, and an auxiliary raw water tank 1301 may be included.

The raw water tank 131 may store raw water. The raw water tank 131 may be disposed above the evaporation chamber 132. The bottom surface of the raw water tank 131 may be an upper surface of the evaporation chamber 132. The raw water tank 131 may supply raw water to the evaporation chamber 132.

The evaporation chamber 132 may evaporate raw water. The evaporation chamber 132 may be disposed below the raw water tank 131. The evaporation chamber 132 may receive and store raw water from the raw water tank 131. The evaporation chamber 132 may evaporate the supplied raw water. The evaporation chamber 132 may receive heat from a heat exchange circulation line 1392 to be described later in order to promote evaporation. In the evaporation chamber 132, raw water may be evaporated to generate water vapor.

The condensation part 133 may be a region in which water vapor generated in the evaporation chamber 132 is condensed. Water vapor generated in the evaporation chamber 132 may move upward and condensate in the condensation part 133. As water vapor is condensed in the condensation part 133, purified water from which contaminants are removed may be formed. The condensation part 133 may be formed on the bottom of the raw water tank 131. For example, the condensation part 133 may be integrally formed with the bottom surface of the raw water tank 131. That is, the condensation part 133 may correspond to the bottom surface of the raw water tank 131. According to this structure, by the cold raw water stored in the raw water tank 131, hot water vapor can be rapidly condensed. At least a portion of the condensation portion 133 may be formed to be inclined downward so that the purified water formed by condensation in the condensation portion 133 can be collected in one place. For example, the condensation portion 133 may be formed to be inclined downward from the central portion toward the edge. That is, the condensation portion 133 may be formed in a shape in which the center rises higher than the edge. According to this structure, even if the raw water tank 131 is disposed on the upper side of the evaporation chamber 132, structural stability can be obtained. Meanwhile, an inclined space S may be formed in a lower portion of the raw water tank 131 to be inclined from the center of the bottom to the edge. Since cold water is denser than warm water, relatively cold raw water may be located in the inclined space S formed under the raw water tank 131. The cold raw water stored in the inclined space S may perform heat exchange with hot steam through the condensing part 133. That is, the hot water vapor is condensed into purified water while taking heat to the cold raw water in the inclined space (S) through the condensation unit 133, and the cold raw water in the inclined space (S) receives heat from the hot water vapor to increase the temperature. I can. The raw water whose temperature has risen in the inclined space S moves to the upper portion of the raw water tank 131 due to a convection phenomenon, and cold raw water may be filled in the inclined space S again. Therefore, since cold raw water is continuously located in the inclined space S where heat exchange with hot steam is performed, condensation of steam can be efficiently promoted.

The water collecting chamber 134 may collect purified water formed by condensation in the condensation part 133. The collection chamber 134 may be disposed at an end of the condensation portion 133 in a direction in which the slope is low. For example, when the central portion of the condensation portion 133 is formed high, the collection chamber 134 may be disposed at the edge of the condensation portion 133. The purified water formed by condensation in the condensation part 133 may flow to the edge along the inclination of the condensation part 133 and may be collected in the water collecting chamber 134 disposed at the edge.

The water purification tank 135 may store purified water formed by condensation in the condensation part 133. To this end, the water collection chamber 134 may deliver the collected purified water to the water purification tank 135. The user may receive purified water from the purification tank 135 and use it as drinking water.

The raw water supply line 136 may supply raw water from the raw water tank 131 to the evaporation chamber 132. The raw water supply line 136 may be connected to a higher slope of the bottom of the raw water tank 131. For example, when the central portion of the raw water tank 131 is formed high, the raw water supply line 136 may be connected to the central portion of the bottom of the raw water tank 131. Due to the difference in density between cold and warm water, relatively warm raw water may be located in the center, rising high from the bottom. Accordingly, the raw water supply line 136 may supply raw water having a relatively high temperature among raw water stored in the raw water tank 131 to the evaporation chamber 132. In addition, since the raw water whose temperature has risen by receiving heat from the hot steam in the inclined space S is moved to the upper portion, the raw water supply line 136 can continuously supply the raw water having a high temperature to the evaporation chamber 132. . According to such a structure, since the raw water preheated in advance by receiving heat from the steam can be supplied to the evaporation chamber 132, evaporation in the evaporation chamber 132 can be promoted. On the other hand, since the raw water supply line 136 is connected to the side with a higher slope, it is possible to structurally filter the sediment deposited in the raw water tank 131. For example, sediment may settle on the lower slope of the raw water tank 131. However, since the raw water supply line 136 is connected to the central portion having a high slope from the bottom surface, raw water without sediment may be supplied to the evaporation chamber 132.

The raw water supply valve 1361 may be applied to the raw water supply line 136. The raw water supply valve 1361 may adjust the amount of raw water supplied from the raw water tank 131 to the evaporation chamber 132. The raw water supply valve 1361 considers at least one of the raw water storage amount of the raw water tank 131, the raw water storage amount of the evaporation chamber 132, the purified water storage amount, and the purified water demand amount of the purified water tank 135 to the evaporation chamber 132. The amount of raw water supplied can be adjusted.

The raw water filter unit 137 may receive raw water from a raw water supply source. The raw water filter unit 137 may remove pollutants of raw water through a filter. The raw water filter unit 137 may supply raw water from which contaminants have been removed to the raw water tank 131. That is, the raw water filter unit 137 may primarily filter contaminants and supply them to the raw water tank 131. The raw water filter unit 137 may include various filters such as a carbon filter, a precipitation filter, a reverse osmosis filter, or a deionization filter. According to this structure, hygiene and cleanliness of the raw water tank 131 can be maintained higher, and the efficiency of purified water can be increased.

The auxiliary raw water tank 1301 may be connected between the raw water filter unit 137 and the raw water tank 131. The auxiliary raw water tank 1301 may receive and store raw water from which contaminants have been removed from the raw water filter unit 137. The auxiliary raw water tank 1301 may supply the stored raw water to the raw water tank 131.

The hot water tank 138 may be a tank in which hot water is generated and stored. The hot water tank 138 may receive and store raw water from which contaminants have been removed from the raw water filter unit 137. The hot water tank 138 may receive heat from a heat exchange circulation line 1392 to be described later. Accordingly, the raw water stored in the hot water tank 138 may become hot water by increasing the temperature. The user can use the hot water stored in the hot water tank 138.

The solar collector 1391 may collect solar heat to heat a thermal circulation medium. The solar collector 1391 is provided with a transparent cover that transmits sunlight rays and prevents heat loss at the upper end, and an absorber plate that absorbs the transmitted sunlight rays and converts it into thermal energy. Is provided, and a heat insulating material may be provided on the bottom surface. A tube through which a thermal circulating medium for collecting heat can pass may be attached to the absorber plate. The heated thermal circulating medium may be circulated and transferred to a device requiring heat along the heat exchange circulation line 1392. If necessary, the solar collector 1391 may further include a Fresnel lens to further increase the heat collection temperature.

A thermal circulation medium may be circulated along the heat exchange circulation line 1392. The heat exchange circulation line 1392 may perform heat exchange with raw water in the evaporation chamber 132 and the hot water tank 138. The heat exchange circulation line 1392 may include heat exchangers respectively disposed in the evaporation chamber 132 and the hot water tank 138. The thermal circulating medium heated by solar heat passes through a heat exchanger disposed in the evaporation chamber 132, and supplies heat to the raw water in the evaporation chamber 132 to promote evaporation. In addition, the thermal circulating medium heated by solar heat passes through a heat exchanger disposed in the hot water tank 138, and supplies heat to raw water in the hot water tank 138 to generate hot water. The heat exchange circulation line 1392 may be connected to the evaporation chamber 132 and the hot water tank 138 in series or in parallel. As shown in FIG. 32, when the heat exchange circulation line 1392 is connected in series with the evaporation chamber 132 and the hot water tank 138, the direction in which the thermal circulation medium circulates may be appropriately set according to the situation. For example, when the production of hot water is further required, the thermal circulation medium may be circulated in a direction toward the hot water tank 138 so that the thermal circulation medium performs heat exchange with the hot water tank 138 first. Alternatively, when the production of purified water is further required, the thermal circulation medium may be circulated in a direction toward the evaporation chamber 132 so that the thermal circulation medium performs heat exchange with the evaporation chamber 132 first. According to this structure, purified water and hot water can be simultaneously produced by using solar heat.

Referring to FIG. 4, the purified water-hot water system 23 according to an embodiment may produce and supply purified water and hot water using solar heat. The purified water-hot water system 23 efficiently circulates and uses heat, thereby increasing the productivity of purified water and hot water.

The evaporation chamber 232 may evaporate the supplied raw water. The evaporation chamber 232 may receive heat from the heat exchange circulation line 2392 to promote evaporation. In the evaporation chamber 232, raw water may be evaporated to generate water vapor.

The condensation part 233 may be a region in which water vapor generated in the evaporation chamber 232 is condensed. The condensation part 233 may be connected to the upper side of the evaporation chamber. The condensation portion 233 may include a pipe. The water vapor generated in the evaporation chamber 232 moves upward and collects into the condensation part 233, and may be condensed while passing through the condensation part 233. By condensing water vapor in the condensing portion 233, purified water from which contaminants have been removed may be formed. The condensation portion 233 may be formed to be inclined downward so that the purified water formed by condensation in the condensation portion 233 can be collected in one place.

The water collecting chamber 234 may collect purified water formed by condensation in the condensation part 233. The collection chamber 234 may be disposed at an end of the condensation portion 233 in a direction in which the slope is low. The purified water formed by condensation in the condensation portion 233 may flow along the slope of the condensation portion 233 and may be collected in the water collecting chamber 234.

The raw water supply line 236 may supply raw water from the raw water tank 231 to the evaporation chamber 232. The raw water supply line 236 may be configured to perform heat exchange with the condensation unit 233. The raw water supply line 236 may be formed to surround at least a portion of the condensation part 233.

Referring to FIG. 4, the raw water supply line 236 may include a winding portion 2362a winding around at least a portion of the condensing portion 233.

Cold raw water supplied through the raw water supply line 236 may perform heat exchange with hot steam passing through the condensing portion 233 while passing through the winding portion 2362a. That is, the hot water vapor is condensed into purified water while passing through the condensation unit 233 while taking heat from the cold raw water passing through the winding unit 2362a, and the cold raw water passing through the winding unit 2362a receives heat from the hot water vapor and receives the temperature. Can rise. According to this structure, it is possible to promote condensation of water vapor in the condensing unit 233 using cold raw water, and at the same time, the cold raw water supplied to the evaporation chamber 232 can be preheated with the heat of hot water vapor. In addition, since heat exchange between raw water and steam is performed in the raw water supply line 236, cold raw water can always be stored in the raw water tank 231, and cold raw water can be continuously supplied to the raw water supply line 236. . The winding portion 2362a may be wound from a lower inclined side to a higher side of the condensed portion 233.

For example, the through portion 2362b may be a portion having a larger cross-sectional area than other portions of the raw water supply line 236. The condensation portion 233 may be formed to directly penetrate the through portion 2362b. According to this structure, cold raw water passing through the through portion 2362b can be directly contacted around the condensation portion 233. Thus, heat exchange between cold raw water and hot steam can be efficiently performed. The through part 2362b may be formed to be inclined upward with respect to the flow direction of the raw water. According to this structure, the raw water passing through the through portion 2362b and the water vapor passing through the condensing portion 233 can flow in opposite directions, so that the raw water and the steam can be continuously heat-exchanged.
