[0034] As a preamble to the embodiments of this application, with the development of industrial and commercial liquid-cooled energy storage systems, liquid chillers may experience coolant leakage during operation. The coolant is composed of 50% ethylene glycol and 50% water, and is toxic and hazardous. Leaked liquid needs to be collected and disposed of properly; indiscriminate discharge will cause environmental pollution. Furthermore, significant coolant leakage can have a substantial impact and cause damage to other components.
[0035] In view of this, embodiments of this application provide a coolant collection and processing device, which aims to solve at least one of the above-mentioned technical problems.
[0036] Please see Figures 1 to 6 As shown in the figure, the coolant collection and treatment device disclosed in this application includes a collection tank 1 and a reaction tank 2. The reaction tank 2 is disposed within the collection tank 1 and has an inlet 21 and an outlet 22. The inlet 21 is used to receive coolant, and the outlet 22 connects the reaction tank 2 and the collection tank 1. The reaction tank 2 contains a reactant (not shown) capable of neutralizing the coolant, positioned between the inlet 21 and the outlet 22. It should be understood that by placing a reactant capable of neutralizing the coolant within the reaction tank 2 and positioning it between the inlet 21 and the outlet 22, the coolant can promptly and fully contact the reactant and undergo a neutralization reaction as it flows through the reaction tank 2, effectively improving the efficiency of coolant neutralization treatment. Placing the reaction tank 2 within the collection tank 1 reduces the area occupied by the device, saving space. The reaction tank 2 and the collection tank 1 are connected through the outlet 22. After the neutralization reaction, the coolant can flow directly into the collection tank 1 for collection. The collection tank 1 provides a temporary storage space for the subsequent coolant treatment process, ensuring the continuity and orderliness of the coolant treatment work, facilitating the unified disposal of the treated coolant, avoiding the random discharge of coolant, and meeting environmental protection requirements.
[0037] Specifically, the reactants in this application undergo a neutralization reaction with the coolant, effectively adjusting the coolant's pH to meet discharge or reuse standards, reducing environmental pollution, and also improving the coolant's recyclability. The reactants can be sodium dihydrogen phosphate (a colorless crystalline powder) and sodium hydroxide solids, etc. The reactants can be evenly distributed within the reaction tank 2, such as by coating the bottom or side walls.
[0038] It should also be understood that, in this embodiment, the liquid inlet 21 is located at the open end of the reaction tank 2, and the liquid outlet 22 is located on the side wall of the reaction tank 2, forming a porous structure.
[0039] In some embodiments, the coolant collection and treatment device further includes a baffle plate 3 disposed within the reaction tank 2. It should be understood that by placing the baffle plate 3 within the reaction tank 2, the flow direction of the coolant is altered due to the obstruction of the baffle plate 3 as it flows through the reaction tank 2. This lengthens the flow path of the coolant within the reaction tank 2, extending the contact time between the coolant and the reactants, which is beneficial for a more complete neutralization reaction and further improves the treatment effect of the coolant. The presence of the baffle plate 3 complicates the flow state of the coolant, creating turbulence, promoting mixing between the coolant and the reactants, and allowing all parts of the coolant to react more evenly with the reactants, reducing the possibility of incomplete local reactions. It should be understood that the baffle plate 3 can guide the coolant to flow along a specific path, making the coolant distribution within the reaction tank 2 more rational, ensuring that the coolant can fully flow through the area where the reactants are located, and improving the utilization rate of the reactants.
[0040] In some embodiments, the surface of the baffle plate 3 is provided with protrusions or grooves. By providing reactants on the protrusions or grooves, the contact area between the coolant and the reactants is increased when the coolant flows through the baffle plate 3. At the same time, the grooves or protrusions further disrupt the flow of the coolant, forming more micro eddies, which makes the mixing of the coolant and the reactants more thorough and enhances the neutralization reaction effect.
[0041] In some embodiments, the baffle plate 3 adopts a porous structure. When the coolant passes through the pores of the baffle plate 3, it will be dispersed into multiple small streams, further increasing the contact area between the coolant and the reactants. At the same time, the porous structure can also play a certain filtering role for the coolant, removing some impurities in the coolant.
[0042] Please see Figure 1As shown, in some embodiments, the coolant collection and treatment device includes multiple baffles 3, which are arranged at intervals. The height of the baffles 3 near the outlet 22 is lower than that of the baffles 3 far from the outlet 22. It should be understood that by arranging multiple baffles 3 at intervals, the flow path of the coolant within the reaction tank 2 and the contact time with the reactants are further increased. By using baffles 3 of different heights to guide the coolant in a gradient manner, the flow rate and direction of the coolant are rationally adjusted according to the reaction stage within the reaction tank 2, ensuring that the coolant maintains a good reaction state throughout the entire reaction process. The lower height of the baffles 3 near the outlet 22 creates a gradient flow of the coolant, making efficient use of space and improving the processing time of the coolant and the uniformity of the reaction with the reactants. Meanwhile, the height difference design of the baffle plate 3 gradually increases the flow rate of the coolant in the reaction tank 2. In the early stage of the reaction, the coolant flow rate is relatively slow, which can fully react with the reactants and effectively prevent the coolant from accumulating locally in the reaction tank 2. This ensures that the coolant is evenly distributed in the reaction tank 2, so that each part of the coolant can be fully treated, thus improving the consistency of coolant treatment. As the reaction proceeds, the coolant gradually approaches the outlet 22, and the flow rate increases. This ensures both the sufficiency of the reaction and the timely discharge of the treated coolant, thereby improving the overall processing efficiency of the device.
[0043] In some embodiments, multiple inclined baffles 3 are spaced apart in the reaction tank 2, with adjacent baffles 3 having opposite inclination directions. After the coolant enters the reaction tank 2, it first impacts the first baffle 3, changing its flow direction to flow upward or downward, and then impacts the next baffle 3 with the opposite inclination. This process is repeated, causing the coolant to flow in an "S" shape in the reaction tank 2, which greatly increases the contact time and contact area between the coolant and the reactants.
[0044] Please see Figure 1 As shown, in some embodiments, among the multiple baffles 3, the height of the baffle 3 closest to the outlet 22 is lower. It is important to understand that by specifying that the height of the baffle 3 closest to the outlet 22 should be lower, the flow rate of the coolant can be more precisely controlled in stages. In the initial stage of the reaction, the coolant flows through the higher baffles 3, slowing its flow rate and ensuring sufficient time for complete reaction with the reactants. As the coolant gradually approaches the outlet 22, it flows through the lower baffles 3, increasing its flow rate and ensuring that the treated coolant is discharged promptly, improving overall processing efficiency. This also avoids problems such as insufficient reaction or excessively long processing time due to unreasonable flow rates. The precise height design makes the flow path of the coolant within the reaction tank 2 more rational, avoiding excessive accumulation of coolant in local areas or abnormal flow rates. Thus, within the limited space of the reaction tank 2, the coolant processing efficiency is maximized, improving the space utilization efficiency of the device.
[0045] Please see Figure 2 and Figure 4 As shown, in some embodiments, the coolant collection and treatment device further includes a leak sensor 4, which is disposed within the reaction tank 2. It should be understood that by installing the leak sensor 4, the state of the reaction tank 2 can be detected. If a leak occurs in the reaction tank 2, the leak sensor 4 can quickly detect it and promptly issue an alarm signal, reminding the operator to take appropriate measures to prevent large-scale coolant leakage from causing environmental pollution and damage to other components of the equipment.
[0046] Please see Figure 6 As shown, in some embodiments, the collection tank 1 is also equipped with a drain valve 5 for discharging the neutralized coolant. It should be understood that by setting the drain valve 5, the opening and closing of the outlet of the collection tank 1 can be controlled, thereby ensuring that the collection tank 1 can collect liquid during leakage, and the accumulated liquid in the collection tank 1 can be discharged uniformly and without pollution, ensuring the orderly operation of the entire coolant collection and treatment system.
[0047] It should be noted that the drain valve 5 and the leakage sensor 4 of this application can work together to achieve automated processing and discharge of leaking liquid.
[0048] Please see Figure 6 As shown, in some embodiments, the coolant collection and treatment device includes a limiting post 6, which is disposed within the collection tank 1 and forms a limiting space with the side wall of the collection tank 1. The reaction tank 2 is disposed within the limiting space. It should be understood that by using the limiting post 6 and the side wall of the collection tank 1 to form the limiting space and positioning the reaction tank 2 within the collection tank 1, displacement and shaking of the reaction tank 2 during operation are prevented, ensuring the stability of the coolant reaction process within the reaction tank 2 and improving the reliability of the device operation. The above-mentioned limiting structure allows for rapid assembly of the collection tank 1 and the reaction tank 2. When maintenance, repair, or replacement of the reaction tank 2 is required, it can also be quickly removed from the limiting space, reducing maintenance difficulty and time costs.
[0049] Please see Figures 2 to 6 As shown in the illustration, this application discloses an energy storage system, including a coolant collection and processing device as described in the above embodiment; the coolant collection and processing device is disposed on the base plate 7 of the energy storage system. It should be understood that the integrated design of the coolant collection and processing device and the energy storage system fully utilizes the space of the base plate 7, making the layout of the entire energy storage system more compact and rational. This reduces wasted space within the system, facilitates the installation and deployment of the energy storage system in different application scenarios, and improves the space utilization efficiency of the energy storage system.
[0050] More specifically, by opening a liquid collection tank 1 on the base plate 7, the base plate 7 becomes multifunctional, reducing the number of parts and making maintenance and repair convenient.
[0051] Please see Figures 2 to 4 As shown, in some embodiments, the energy storage system further includes a leak collection tray 8 and a guide pipe 9. The leak collection tray 8 is disposed within the energy storage system; the guide pipe 9 connects the leak collection tray 8 to the reaction tank 2, and is used to guide the coolant in the leak collection tray 8 into the reaction tank 2. It should be understood that the installation of the leak collection tray 8 and the guide pipe 9 greatly enhances the energy storage system's ability to cope with coolant leaks. In the event of a leak, the leak collection tray 8 can quickly collect the leaked coolant, preventing it from flowing freely within the energy storage system and causing damage such as short circuits and corrosion. Guiding the leaked coolant to the reaction tank 2 through the guide pipe 9 allows for timely treatment of the leaked coolant, further improving the safety and stability of the energy storage system. Guiding the coolant collected by the leak collection tray 8 to the reaction tank 2 achieves environmentally friendly treatment of the leaked coolant.
[0052] This application also discloses a base plate 7 structure, including a base plate 7 and a coolant collection and treatment device as described in the above embodiments. Therefore, it can possess all the technical features and effects of the aforementioned coolant collection and treatment device, which will not be repeated here.
