Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of energy storage container, especially relates to a dehumidification system of energy storage container. BACKGROUND

[0002] Energy storage containers are widely used in energy storage and power systems, especially during the charging and discharging process of energy storage batteries, the batteries release a large amount of heat, causing the internal temperature to rise. Therefore, it is usually necessary to equip a refrigeration device to reduce the temperature inside the energy storage container and ensure that the energy storage batteries and their environment are in a safe working condition. However, due to the temperature difference between the inside of the energy storage container and the outside environment, it is easy to cause the internal moisture to condense into water droplets on the top of the energy storage container and the surface of the battery. This condensation phenomenon not only affects the safety of the energy storage equipment, but also may cause circuit short circuit and electrical failure, and in severe cases, it may even affect the stability and service life of the energy storage system.

[0003] In order to reduce the condensation in the energy storage container, the existing technology usually adopts the methods of controlling the temperature inside the container, using industrial air conditioning dehumidification mode or placing dehumidifier, etc. Specifically, the industrial air conditioning dehumidification mode removes moisture by reducing the overall temperature, but its disadvantage is high energy consumption, inaccurate dehumidification effect, and unable to effectively control according to the humidity conditions of different areas. In addition, although the traditional dehumidifier can absorb moisture, its effect is limited, and it cannot maintain the dehumidification effect for a long time, and the overall solution has poor economy and reliability.

[0016] On the basis of the above technical scheme, preferably, the liquid discharge pipe and the box body are provided with a sealing element at the connection position.

[0017] Compared with the prior art, the utility model has the following beneficial effects:

[0018] (1) The energy storage container dehumidification system disclosed by the utility model constructs a closed loop flow system through the air suction pipeline, the cluster dehumidifier, the air return pipeline and the plug-in box chamber. Firstly, the humidity is extracted from each plug-in box chamber to the cluster dehumidifier through the air suction pipeline, and after the dehumidification treatment, the dry air is sent back to the plug-in box chamber through the air return pipeline. The structure arrangement ensures the rapid removal of humidity and effective control of humidity. Since the dehumidification system adopts the design of local dehumidification and dry air return, the humidity in each energy storage cluster can be processed individually.

[0020] (3) Through the setting of the humidity sensor and the controller, the humidity sensor is responsible for real-time monitoring of the humidity level in the plug-in box chamber. The controller judges whether the air suction electromagnetic valve and the air return electromagnetic valve need to be opened or closed according to the real-time data from the humidity sensor, and adjusts the operating state of the cluster dehumidifier. The humidity sensor and the controller are linked to make the system have automatic adjustment capability. The controller automatically controls the opening and closing of the air suction electromagnetic valve and the air return electromagnetic valve according to the change of humidity in different areas, adjusts the working state of the cluster dehumidifier, thereby avoiding excessive dehumidification of the plug-in box chamber or energy waste, and the humidity control of each area is more accurate, which improves the overall dehumidification efficiency and system energy efficiency.

[0021] (4) Through the setting of the main dehumidifier, when the cluster dehumidifier corresponding to a certain energy storage cluster fails, the main dehumidifier can participate in the dehumidification task in time, ensuring that the humidity control in the energy storage container is not affected, thereby improving the fault tolerance, reliability and stability of the system.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the present application will be described clearly and completely in combination with the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] As shown in the figure, in combination with the present application, the present application discloses an energy storage container dehumidification system, comprising a box 1 and a plurality of dehumidification assemblies 2. Figure 1 Figure 2

[0029] Among them, the box 1 is a cuboid structure, and a plurality of energy storage clusters 11 are arranged inside along the length direction thereof, the energy storage cluster 11 is an independent space, and a plurality of plug-in box chambers 12 are arranged in each energy storage cluster 11 along the height direction, and the plug-in box chamber 12 is used for storing battery packs.

[0030] ​​In order to realize the dehumidification of the inside of the box 1, the energy storage container dehumidification system of the embodiment is provided with a plurality of dehumidification assemblies 2, which are respectively arranged in the energy storage clusters 11. By means of the arrangement, each dehumidification assembly 2 respectively performs dehumidification operation on the corresponding energy storage cluster 11. Specifically, the dehumidification assembly 2 comprises a cluster dehumidifier 21, an air suction pipeline 22 and an air return pipeline 23.

[0031] The cluster dehumidifier 21 is arranged at the top end or the bottom end of the energy storage cluster 11. The cluster dehumidifier 21 is used as a core device for dehumidification work and reduces the humidity inside the energy storage container by absorbing moisture in the air. The arrangement position (top or bottom) can be optimized according to the characteristics of air flow to improve the dehumidification efficiency.

[0032] One end of the air suction pipeline 22 is connected with the inlet end of the cluster dehumidifier 21, and the other end sequentially passes through each box insertion chamber 12. The air suction pipeline 22 is used for sucking the humidity in the box insertion chamber 12 into the cluster dehumidifier 21. The air suction pipeline 22 can help to concentrate and effectively suck humidity from the plurality of box insertion chambers 12, so as to ensure that the humidity of the plurality of box insertion chambers 12 in the energy storage cluster 11 is effectively controlled.

[0033] One end of the air return pipeline 23 is connected with the outlet end of the cluster dehumidifier 21, and the other end sequentially passes through each box insertion chamber 12. The air return pipeline 23 is used for introducing the dehumidified air into the box insertion chamber 12. Such a structure can ensure that the dry air after dehumidification is uniformly distributed in each box insertion chamber 12, effectively reducing the humidity.

[0034] The energy storage container dehumidification system disclosed in the embodiment forms a closed loop flow system through the air suction pipeline 22, the cluster dehumidifier 21, the air return pipeline 23 and the box insertion chamber 12. First, the humidity is sucked from each box insertion chamber 12 to the cluster dehumidifier 21 through the air suction pipeline 22, and then the dry air is sent back to the box insertion chamber 12 through the air return pipeline 23 after dehumidification. Such a structure ensures the rapid removal of humidity and effective control of humidity.

[0035] Since the dehumidification system adopts the design of local humidity extraction and dry air return, the humidity in each energy storage cluster 11 can be processed individually. Compared with the traditional whole dehumidification mode of industrial air conditioner or dehumidifier, the system has higher energy efficiency. The localized dehumidification design can accurately regulate according to the humidity demand of different areas, avoiding unnecessary energy consumption of the whole system.

[0036] Compared with the traditional dehumidification mode using industrial air conditioner or dehumidifier, the design of the dehumidification assembly 2 is simple and efficient, and can be operated stably for a long time, reducing the maintenance frequency and cost. In addition, the design of the cluster dehumidifier 21, the air suction pipeline 22 and the air return pipeline 23 makes the system structure more modular, and it is also relatively convenient to repair and replace parts.

[0037] As some preferred embodiments, the air suction pipeline 22 comprises a cluster air suction pipeline 221 and a plurality of box air suction pipelines 222, one end of the cluster air suction pipeline 221 is connected with the inlet end of the cluster dehumidifier 21, the other end of the cluster air suction pipeline 221 sequentially passes through each box chamber 12, the plurality of box air suction pipelines 222 are respectively located in the box chamber 12 and connected with the cluster air suction pipeline 221, each box air suction pipeline 222 is responsible for sucking the humidity from the respective box chamber 12, and then transmits the humidity to the cluster dehumidifier 21 for dehumidification operation, each box chamber 12 has a separate air suction pipeline 22, so that the humidity of each box chamber 12 can be independently processed, avoiding the problem of uneven or incomplete humidity extraction that may occur in the traditional design.

[0038] The air return pipeline 23 comprises a cluster air return pipeline 231 and a plurality of box air return pipelines 232, one end of the cluster air return pipeline 231 is connected with the outlet end of the cluster dehumidifier 21, the other end of the cluster air return pipeline 231 sequentially passes through each box chamber 12, the plurality of box air return pipelines 232 are respectively located in the box chamber 12 and connected with the cluster air return pipeline 231, and are responsible for introducing dry air into each box chamber 12 to ensure air circulation and timely removal of humidity.

[0039] By dividing the air suction and return system, each box chamber 12 of each energy storage cluster 11 can independently perform humidity extraction and dry air return. This design greatly improves the dehumidification efficiency, reduces the retention of humidity in the container, and ensures the safe and stable operation of the energy storage device in a low humidity environment.

[0040] In order to reduce the dehumidification energy consumption, the embodiment also constructs the following scheme.

[0041] Specifically, the air suction pipeline 22 further comprises an air suction electromagnetic valve 223 arranged on the box air suction pipeline 222, and the air return pipeline 23 further comprises an air return electromagnetic valve 233 arranged on the box air return pipeline 232. The use of the electromagnetic valve enables the system to selectively perform humidity extraction and dry air return as needed, avoiding unnecessary energy consumption. Only the box chamber 12 with excessive humidity will open the corresponding air suction and return pipeline 23, improving the overall energy efficiency of the system.

[0042] The energy storage container dehumidification system of the embodiment further comprises a controller 4 and a plurality of humidity sensors 3, the plurality of humidity sensors 3 are respectively located in the box chamber 12, and the humidity sensor 3, the air suction electromagnetic valve 223, the air return electromagnetic valve 233 and the cluster dehumidifier 21 are respectively electrically connected with the controller 4.

[0043] The above technical solution is sampled, the humidity sensor 3 is responsible for real-time monitoring of the humidity level in the box chamber 12, the controller 4 judges whether the suction electromagnetic valve 223 and the return air electromagnetic valve 233 need to be opened or closed according to the real-time data from the humidity sensor 3, and adjusts the running state of the cluster dehumidifier 21, and can also adjust the size of the opening of the electromagnetic valve. The linkage of the humidity sensor 3 and the controller 4 enables the system to have automatic adjustment capability. The controller 4 automatically controls the opening and closing of the suction electromagnetic valve 223 and the return air electromagnetic valve 233 and the size of the opening according to the change of the humidity of different areas, adjusts the working state of the cluster dehumidifier 21, thereby avoiding excessive dehumidification of the box chamber 12 or energy waste, the humidity control of each area is more accurate, and the overall dehumidification efficiency and system energy efficiency are improved.

[0044] In the embodiment, the cluster suction pipe 221 and the cluster return air pipe 231 are respectively vertically located on both sides of the width direction of the energy storage cluster 11. The direction of air flow is optimized, and the humidity is more easily removed, thereby improving the overall dehumidification effect of the system.

[0045] When a certain cluster dehumidifier 21 fails and cannot be normally dehumidified and cannot be disassembled and repaired in a short time, it will affect the dehumidification operation of all the box chambers 12 of the energy storage cluster 11, therefore, the embodiment constructs the following technical solution to solve the problem.

[0046] Specifically, the embodiment further provides a main dehumidifier 5, a main suction pipe 6 and a main return air pipe 7 in the box 1, one end of the main suction pipe 6 is connected with the inlet of the main dehumidifier 5, the other end is connected with the inlets of the cluster dehumidifiers 21 in parallel, one end of the main return air pipe 7 is connected with the outlet of the main dehumidifier 5, the other end is connected with the outlets of the cluster dehumidifiers 21 in parallel, and the inlet of each main dehumidifier 5 and the main suction pipe 6, the outlet and the main return air pipe 7 are provided with auxiliary electromagnetic valves W, and the main dehumidifier 5 and the auxiliary electromagnetic valves W are electrically connected with the controller 4.

[0047] Therefore, when the humidity detected by the plurality of humidity sensors 3 in a certain energy storage cluster 11 is large for a long time, it indicates that the cluster dehumidifier 21 corresponding to the energy storage cluster 11 has a fault, at this time, the controller 4 opens the auxiliary electromagnetic valve W corresponding to the inlet and outlet of the faulty cluster dehumidifier 21, and synchronously starts the main dehumidifier 5, the main dehumidifier 5 sucks the humidity in the plurality of plug-in box chambers 12 in the faulty energy storage cluster 11 through the main air suction pipe 6 and the air suction pipe 22, and then completes the dehumidification operation, and then the dried air is transported into the plurality of plug-in box chambers 12 in the faulty energy storage cluster 11 through the main air return pipe 7 and the air return pipe 23, so as to ensure that the plurality of plug-in box chambers 12 in the energy storage cluster 11 can be dehumidified in time, and ensure that the humidity control in the energy storage container is not affected, thereby improving the fault tolerance, reliability and stability of the system. Combined with the intelligent management of the controller 4, the automatic level of the dehumidification system is greatly improved, and the fault response ability of the equipment is enhanced, and the long-term stable operation of the system is ensured.

[0048] In the daily dehumidification process, the cluster dehumidifier 21 is mainly used to complete the dehumidification operation of the energy storage container, and the main dehumidifier 5 is used as an auxiliary dehumidification function. When the cluster dehumidifier 21 fails, the main dehumidifier 5 can take over the dehumidification task in time, so as to ensure that the humidity control in the energy storage container is not affected.

[0049] However, when the cluster dehumidifier 21 works for a long time, a large amount of condensed water will accumulate in the cluster dehumidifier 21, which will reduce the initial efficiency of the cluster dehumidifier 21. Therefore, the cluster dehumidifier 21 is provided with a cluster liquid level sensor 210 electrically connected with the controller 4, which is used to detect the liquid level of the condensed water in the cluster dehumidifier 21.

[0050] Therefore, when the cluster liquid level sensor 210 detects that the liquid level of the condensed water in the cluster dehumidifier 21 is high, it indicates that the dehumidification efficiency of the cluster dehumidifier 21 is reduced, and the condensed water needs to be discharged. At this time, the controller 4 controls the main dehumidifier 5 and the auxiliary electromagnetic valve W corresponding to the inlet and outlet of the cluster dehumidifier 21, so that the main dehumidifier 5 can suck the condensed water in the cluster dehumidifier 21 while dehumidifying the plug-in box chamber 12 corresponding to the cluster dehumidifier 21. When the cluster liquid level sensor 210 is below a certain threshold, the main dehumidifier 5 and the auxiliary electromagnetic valve W corresponding to the inlet and outlet of the cluster dehumidifier 21 are closed, and the corresponding cluster dehumidifier 21 is started, so that the cluster dehumidifier 21 continues to perform normal dehumidification operation.

[0051] Since the main dehumidifier 5 will also produce condensed water when sucking the condensed water in the cluster dehumidifier 21 and participating in the dehumidification task, it is necessary to discharge the condensed water in the main dehumidifier 5 in time according to the content of the condensed water, so as to avoid reducing the working efficiency of the main dehumidifier 5.

[0052] The scheme adopted in the embodiment is that a main liquid level sensor 51 is further arranged in the main dehumidifier 5, which is used for detecting the liquid level of the condensed water in the main dehumidifier 5, and a liquid discharge pipe 52 is further arranged at the bottom of the main dehumidifier 5, the end of the liquid discharge pipe 52 extends outside the box body 1, a liquid discharge electromagnetic valve 53 is arranged on the liquid discharge pipe 52, and the main liquid level sensor 51 and the liquid discharge electromagnetic valve 53 are connected with the controller 4.

[0053] Therefore, when the main liquid level sensor 51 detects that the liquid level of the condensed water is too high, the controller 4 controls the liquid discharge electromagnetic valve 53 to be opened, so that the condensed water in the main dehumidifier 5 is discharged outside the box body 1 through the liquid discharge pipe 52, and the main dehumidifier 5 can ensure a normal working state, in addition, intelligent monitoring is not required to be manually operated, so that the energy storage container can be dehumidified in a high-efficiency, energy-saving and environment-friendly mode.

[0054] Preferably, the connection part of the liquid discharge pipe 52 and the box body 1 is provided with a sealing member 8, through the arrangement of the sealing member 8, external water vapor can be prevented from entering the inside of the box body 1 through the connection part of the liquid discharge pipe 52 and the box body 1, and the sealing reliability of the box body 1 can be ensured.

[0055] The above only describes the preferred embodiments of the utility model and is not used to limit the utility model, any modification, equivalent replacement, improvement and the like made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
