Abstract
Description
Technical Field
[0001] This application relates to the field of waste incineration power generation technology, and in particular to an energy storage device for waste incineration power generation. Background Technology
[0002] Waste-to-energy incineration is a device that converts the heat energy generated by incinerating waste into electrical energy. However, because the electrical energy generated by incinerating waste is fluctuating and unstable, some of the electrical energy cannot be fully utilized. Therefore, it is necessary to store the electrical energy to avoid energy waste.
[0003] One related method for storing electrical energy in waste incineration power generation is to use a hydroelectric power generation system. When excess electrical energy needs to be stored, the excess electrical energy is used to drive a water pump to transport water to a high-level water tank for storage. When the demand for electricity increases, the water in the high-level water tank is released to drive a water turbine to generate electricity, thereby realizing the storage and reuse of electrical energy.
[0004] When using the above-mentioned methods to store electrical energy, the requirements for terrain are relatively high, so it can only be applied under specific geographical conditions. Furthermore, the loss of electrical energy is relatively large when using the above-mentioned methods to store electrical energy, resulting in low energy storage efficiency, which in turn cannot meet the demand when the electricity consumption is large. Utility Model Content
[0005] In order to improve the storage efficiency of electrical energy, this application provides an electrical energy storage device for waste incineration power generation.
[0006] This application provides an energy storage device for waste incineration power generation, which adopts the following technical solution: An energy storage device for waste incineration power generation includes: The outer casing is fixedly installed on the ground. An energy storage device is fixedly installed inside the outer casing. The energy storage device is capable of converting the alternating current generated by incinerating waste into direct current and storing it.
[0007] By adopting the above technical solution, when it is necessary to store excess electrical energy generated from waste incineration, an energy storage device for the alternating current (AC) generated by waste incineration is electrically connected to the energy storage device. After the energy storage device is electrically connected to the energy storage device, the AC generated by waste incineration can enter the energy storage device. After the AC enters the energy storage device, the energy storage device can convert the AC into direct current (DC) and store the converted DC, thereby achieving the purpose of storing excess electrical energy. By storing the electrical energy generated from waste incineration in this way, the energy loss that occurs when the electricity drives the water pump to transport water to the elevated water tank is avoided, thus effectively improving the efficiency of energy storage.
[0008] Optionally, the energy storage device includes: A transformer, which is fixedly installed on the ground and electrically connected to the waste-to-energy incineration equipment; A rectifier diode is fixedly disposed inside the housing and is electrically connected to the transformer. A capacitor module is fixedly disposed inside the housing and is electrically connected to the rectifier diode. A voltage regulator, which is fixedly disposed inside the housing and electrically connected to the capacitor module; The lithium-ion battery includes multiple lithium-ion batteries, each of which is fixedly disposed within the casing. The lithium-ion battery is electrically connected to the voltage regulator, and each lithium-ion battery is connected in series with the others.
[0009] By adopting the above technical solution, when it is necessary to store the electrical energy generated by incinerating waste, the transformer is electrically connected to the energy storage device for waste-to-energy power generation. After the transformer is electrically connected to the energy storage device, the AC power generated by incinerating waste can be stepped down. The stepped-down AC power is then passed to a rectifier diode, and after passing through the rectifier diode, the AC power is converted into DC power. The converted DC power enters the capacitor module for filtering. The filtered DC power ensures that the current output from the capacitor module is stable and does not fluctuate. The filtered DC power enters the voltage regulator, which further regulates the DC power to ensure that the DC power output from the voltage regulator is stable. The stable DC power flows out of the voltage regulator and enters the lithium-ion battery. Since multiple lithium-ion batteries are connected in series, the DC power entering the lithium-ion battery can be evenly distributed to each lithium-ion battery, thereby achieving the purpose of storing the electrical energy generated by incinerating waste. By storing the electrical energy generated from incinerating waste in the above manner, the energy loss that occurs when the electrical energy drives the water pump to transport water to the high-level water tank is avoided, thereby effectively improving the efficiency of storing electrical energy.
[0010] Optionally, a plurality of heat dissipation holes are provided at intervals on one side of the housing, and a heat dissipation component is rotatably disposed on the housing, the heat dissipation component comprising: A cooling fan is rotatably mounted on the side of the housing away from the heat dissipation holes; A filter plate is fixedly disposed inside the housing, and the filter plate is located on the side of the housing near the heat dissipation hole.
[0011] By adopting the above technical solution, since multiple lithium-ion batteries are connected in series, they generate a significant amount of heat during energy storage. Activating the cooling fan draws cool air from outside the casing into the battery, cooling the lithium-ion batteries inside. The filter plate removes impurities from the incoming air, preventing them from adhering to electrical components and causing short circuits or damage. This method of cooling the lithium-ion batteries prevents damage due to overheating, effectively improving the stability of lithium-ion energy storage.
[0012] Optionally, each of the lithium-ion batteries is fixedly provided with heat dissipation fins on both sides, and the heat dissipation fins are fixedly connected to the lithium-ion battery by thermally conductive adhesive.
[0013] By adopting the above technical solution, the heat dissipation fins are fixedly connected to the lithium-ion battery through thermally conductive adhesive. The thermally conductive adhesive ensures that the heat generated by the lithium-ion battery can be quickly transferred to the heat dissipation fins. The heat dissipation fins ensure that after the cooling fan draws cold air into the casing, the cold air can quickly carry away the heat on the heat dissipation fins, thereby further improving the efficiency of heat dissipation treatment of lithium-ion batteries.
[0014] Optionally, multiple cooling fans are provided at intervals along the housing.
[0015] By adopting the above technical solution, the arrangement of multiple cooling fans allows cold air from outside the casing to quickly enter the casing, and the arrangement of multiple cooling fans ensures that the cold air from outside the casing can enter the casing evenly, avoiding the situation where the cold air can only dissipate heat on part of the lithium-ion battery after entering the casing, thereby further improving the comprehensiveness of heat dissipation treatment of lithium-ion batteries.
[0016] Optionally, multiple moisture-proof cotton layers are fixedly disposed inside the outer casing.
[0017] By adopting the above technical solution, the moisture-proof cotton layer can absorb the water vapor that enters the casing with the cold air, avoiding the situation where water vapor adheres to the surface of electrical components during the heat dissipation treatment of lithium-ion batteries, which may cause short circuits or corrosion of the electrical components, thereby further improving the stability of the heat dissipation treatment of lithium-ion batteries.
[0018] Optionally, a grounding terminal is fixedly provided on one side of the housing.
[0019] By adopting the above technical solution, the grounding terminal can release the charge generated by the electrical components during operation, avoiding damage to the electrical components due to static electricity accumulation, thereby further improving the stability of the electrical components during operation.
[0020] Optionally, a door is rotatably provided on the side of the housing away from the grounding end.
[0021] By adopting the above technical solution, when the moisture-proof cotton layer and electrical components inside the shell need maintenance, the door can be rotated and opened to replace and maintain the moisture-proof cotton layer and electrical components inside the shell, thereby making it easier to inspect and maintain the various components inside the shell, and thus effectively improving the convenience of maintaining the electrical components inside the shell.
[0022] In summary, this utility model embodiment provides an energy storage device for waste incineration power generation, which includes at least one of the following beneficial technical effects: 1. When it is necessary to store excess electrical energy generated from waste incineration, an energy storage device for the alternating current (AC) generated by waste incineration is electrically connected to the energy storage device. After the connection, the AC power generated by waste incineration enters the energy storage device. Once inside, the energy storage device converts the AC power into direct current (DC) power and stores the converted DC power, thus achieving the purpose of storing excess electrical energy. Storing electrical energy generated from waste incineration in this way avoids energy loss during the process of driving a water pump to transport water to an elevated water tank, thereby effectively improving the efficiency of energy storage.
[0023] 2. When it is necessary to store the electrical energy generated by incinerating waste, the transformer is electrically connected to the energy storage device for waste-to-energy power generation. After the transformer is electrically connected to the energy storage device, the AC power generated by incinerating waste is stepped down. The stepped-down AC power is then passed to a rectifier diode, and after passing through the rectifier diode, the AC power is converted into DC power. The converted DC power enters the capacitor module for filtering. The filtered DC power ensures that the current output from the capacitor module is stable and does not fluctuate. The filtered DC power enters the voltage regulator, which further regulates the DC power to ensure that the DC power output from the voltage regulator is stable. The stable DC power flows out of the voltage regulator and enters the lithium-ion battery. Since multiple lithium-ion batteries are connected in series, the DC power entering the lithium-ion battery is evenly distributed to each lithium-ion battery, thereby achieving the purpose of storing the electrical energy generated by incinerating waste. By storing the electrical energy generated from incinerating waste in the above manner, the energy loss that occurs when the electrical energy drives the water pump to transport water to the high-level water tank is avoided, thereby effectively improving the efficiency of storing electrical energy.
[0024] 3. Because multiple lithium-ion batteries are connected in series, they generate considerable heat during energy storage. Activating the cooling fan draws cool air from outside the casing into the battery compartment, cooling the lithium-ion batteries inside. The filter plate removes impurities from the incoming air, preventing them from adhering to electrical components and causing short circuits or damage. This method of cooling the lithium-ion batteries prevents damage due to overheating, effectively improving the stability of lithium-ion energy storage. Attached Figure Description

Detailed Implementation
[0027] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0028] Combination Figure 1 This application discloses an energy storage device for waste incineration power generation, including a shell 1 and an energy storage component 2. The shell 1 is fixedly installed on the ground, and the energy storage component 2 is fixedly installed inside the shell 1. The energy storage component 2 can convert the alternating current generated by incinerating waste into direct current and store it.
[0029] In this embodiment, the outer shell 1 is a rectangular structure and is fixed to the ground by bolt connection. The energy storage component 2 matches the specifications of the outer shell 1 and is connected to the energy storage device in the waste incineration power generation system by wire 11.
[0030] In practical use, when it is necessary to store the excess electrical energy generated by incinerating waste, the energy storage device 2 is connected to the energy storage equipment of the waste incineration power generation system through the wire 11. After the energy storage equipment is connected to the energy storage device 2, the alternating current generated by incinerating waste is transmitted to the energy storage device 2 through the wire 11. After entering the energy storage device 2, the alternating current is converted into direct current and stored in the energy storage device 2.
[0031] Combination Figure 2 and Figure 3 In a specific embodiment, the energy storage device 2 includes a transformer 21, a rectifier diode 22, a capacitor module 23, a voltage regulator 24, and a lithium-ion battery 25. The transformer 21 is fixedly installed on the ground and electrically connected to the waste incineration power generation equipment. The rectifier diode 22 is fixedly installed inside the housing 1 and electrically connected to the transformer 21. The capacitor module 23 is fixedly installed inside the housing 1 and electrically connected to the rectifier diode 22. The voltage regulator 24 is fixedly installed inside the housing 1 and electrically connected to the capacitor module 23. Multiple lithium-ion batteries 25 are provided, each lithium-ion battery 25 is fixedly installed inside the housing 1, and the lithium-ion battery 25 is electrically connected to the voltage regulator 24. Each lithium-ion battery 25 is connected in series with the others. Multiple heat dissipation holes 31 are spaced apart on one side of the outer casing 1. A heat dissipation component 3, including a cooling fan 32 and a filter plate 33, is rotatably mounted on the outer casing 1. The cooling fan 32 is rotatably mounted on the side of the outer casing 1 away from the heat dissipation holes 31, and the filter plate 33 is fixedly mounted inside the outer casing 1, located on the side of the outer casing 1 closest to the heat dissipation holes 31. Each lithium-ion battery 25 has heat dissipation fins 4 fixedly mounted on both sides, and the heat dissipation fins 4 are fixedly connected to the lithium-ion battery 25 by thermally conductive adhesive. Multiple cooling fans 32 are spaced apart along the outer casing 1. Multiple moisture-proof cotton layers 5 are fixedly mounted inside the outer casing 1. A door 6 is rotatably mounted on the side of the outer casing 1 away from the grounding terminal 7.
[0032] In this embodiment, the transformer 21 is fixed to the ground by bolts. The transformer 21 is connected to the energy storage device for waste incineration via wire 11. The rectifier diode 22 is fixed inside the casing 1 by a clamping strip and is connected to the transformer 21 via wire 11. The capacitor module 23 can be fixed to the casing 1 by integral molding or by bolts. The capacitor module 23 is connected to the rectifier diode 22 via wire 11. The voltage regulator 24 can be fixed to the casing 1 by integral molding or by bolts; no specific limitation is made in this embodiment. The voltage regulator 24 is connected to the capacitor module 23 via wire 11. The lithium-ion battery 25 is fixed to the casing 1 by bolts and is connected to the voltage regulator 24 via wire 11. The heat dissipation hole 31 is circular. The cooling fan 32 is fixed to the casing 1 by bolts. The filter plate 33 can be fixed to the casing 1 by integral molding or by welding; no specific limitation is made in this embodiment. The moisture-proof cotton layer 5 is fixedly connected to the outer shell 1 by adhesive bonding. The door 6 has a rectangular structure.
[0033] In practical use, when it is necessary to store the excess electrical energy generated by incinerating waste, transformer 21 is connected to the energy storage device in the waste incineration power generation system. After the transformer 21 is connected to the energy storage device, the high-voltage current generated by incinerating waste can be transmitted to transformer 21 and the high-voltage current is stepped down. After being stepped down by transformer 21, the high-voltage current is transmitted to rectifier diode 22. The stepped-down current is converted from AC to DC by rectifier diode 22. After being converted from AC to DC, it is transmitted to capacitor module 23 for filtering. After being filtered by capacitor module 23, the DC current can be ensured to maintain a stable output current. After being filtered by capacitor module 23, the DC current is transmitted to voltage regulator 24. Voltage regulator 24 further regulates the DC current to ensure that the DC voltage remains constant. The stable DC current regulated by voltage regulator 24 is transmitted to lithium-ion battery 25. Since multiple lithium-ion batteries 25 are connected in series, the stable DC current can be evenly distributed to each lithium-ion battery 25, thereby achieving the purpose of storing the excess electrical energy generated by incinerating waste.
[0034] During the energy storage process of the lithium-ion battery 25, heat is generated during charging. To prevent the lithium-ion battery 25 from overheating, multiple cooling fans 32 are activated during energy storage. These fans draw cool air from outside the casing 1 into the casing 1, quickly removing the heat generated during charging. The thermally conductive adhesive and heat sink fins 4 allow the heat generated during charging to be transferred to the heat sink fins 4. Because the heat sink fins 4 have a large heat dissipation area, the cool air quickly removes the heat from the heat sink fins 4 when the cooling fans 32 draw it in, further improving the heat dissipation efficiency of the lithium-ion battery 25. After the cool air enters the casing 1, the filter plate 33 intercepts impurities in the air, preventing them from entering the casing 1 and adhering to the surface of electrical components, thus affecting their normal operation. The moisture-proof cotton layer 5 absorbs moisture that enters the casing 1 with the cold air, preventing moisture in the air from corroding electrical components. After the filter plate 33 and the moisture-proof cotton layer 5 have been used for a period of time, a lot of impurities and moisture will accumulate on them. At this time, the door 6 can be turned to clean and replace the filter plate 33 and the moisture-proof cotton layer 5.
[0035] Combination Figure 1 In a specific embodiment, a grounding terminal 7 is fixedly provided on one side of the outer casing 1. In actual use, the grounding terminal 7 can conduct the static electricity generated by the lithium-ion battery 25 during current storage and by electrical components during operation to the ground, thereby avoiding damage to electrical components due to static electricity accumulation.
[0036] The principle of this embodiment is as follows: When it is necessary to store the excess electrical energy generated by incinerating waste, the energy storage device 2 is connected to the energy storage device of the waste incineration power generation system through the wire 11. After the energy storage device is connected to the energy storage device 2, the alternating current generated by incinerating waste is transmitted to the energy storage device 2 through the wire 11. After the alternating current enters the energy storage device 2, it can be converted into direct current and stored in the energy storage device 2.
