Description

Technical Field

[0001] This invention relates to the field of air purification, specifically to an intelligent ventilation and air purification structure for an energy storage container. Background Technology

[0002] Energy storage containers are modular energy storage units that integrate energy storage battery systems, battery management systems, temperature control systems, and fire protection systems within a standard container structure. They are widely used in power storage and peak-shaving scenarios on the generation, grid, and user sides. Because the densely deployed energy storage batteries inside the container generate a large amount of heat during charging and discharging, energy storage containers must be equipped with reliable temperature control systems.

[0003] Air conditioning is the most commonly used active temperature control device. By cooling or heating, it maintains the internal temperature of the container within the optimal range of 15℃-25℃ for battery operation, ensuring the safe, stable, and long-term operation of the energy storage system. At the same time, the air circulation during the operation of the air conditioner can also promote the uniform distribution of internal gas. Combined with the ventilation design, it can achieve orderly exchange of gas inside and outside the container, avoiding the local accumulation of harmful gases.

[0004] The aforementioned existing technologies have the following drawbacks: In the traditional ventilation structure design of energy storage containers, the air conditioner is usually directly installed on the container's door—that is, the air conditioner unit is embedded or externally mounted on the door panel, and the air inlet of the air conditioner faces the outside of the container horizontally or obliquely. In severe weather conditions such as the rainy season or when there is a lot of wind and sand, strong winds carrying rainwater and sand can directly impact the air inlet area horizontally, causing the internal filter components to quickly become clogged or even fail. Rainwater may also seep into the air conditioner or the container, causing battery short circuits or electrical equipment failures.

[0005] Therefore, an intelligent ventilation and air purification structure for energy storage containers is proposed to address the above problems. Summary of the Invention

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Specific implementation examples are given below.

[0024] Please see Figures 1 to 10 As shown in the figure, an intelligent ventilation and air purification structure for an energy storage container according to an embodiment of the present invention includes: a container body 1, wherein the side wall of the container body 1 is provided with an exhaust port; an outer shell 12, which is fixedly installed on the top of the container body 1; an air conditioner 13, which is fixedly installed inside the outer shell 12, having an air inlet end and an air outlet end, and the air outlet end is fixedly provided with an air outlet pipe 15 located at the top of the inner part of the container body 1; an air inlet unit, which is installed on the outer shell 12, including an air inlet located at the bottom of the end of the outer shell 12 and an air inlet pipe 14 located inside the outer shell 12, wherein the air inlet and the exhaust port are detachably provided with mesh plates 16, one end of the air inlet pipe 14 is connected to the air inlet, and the other end is connected to the air inlet end of the air conditioner 13, and the air inlet pipe 14 is provided with a dehumidifying plate 17 for dehumidifying the incoming air; and a regeneration mechanism, which is installed inside the outer shell 12, including a hot air blower 3 fixedly installed inside the outer shell 12; the hot air blower 3 is used to deliver hot air to the dehumidifying plate 17 for thermal regeneration, and its input end is connected to the outside air; During operation, the air conditioner 13 starts running according to preset parameters and creates negative pressure in the air inlet duct 14. External air enters through the air inlet at the bottom of the outer casing 12 under the influence of the pressure difference. Because the air inlet is located at the bottom, large particles in the external air are not easily drawn up by the airflow due to their own gravity, achieving gravity settling and separation. After entering the air inlet, the air first passes through the mesh plate 16, which intercepts and filters suspended particles in the air. Then, the air enters the air inlet duct 14 and passes through the dehumidifier plate 17. The wet plate 17 can absorb moisture from the air. The dehumidified air enters the air inlet of the air conditioner 13. After temperature adjustment, it enters the air outlet duct 15 from the air outlet. The bottom of the air outlet duct 15 has an air vent, which allows airflow to enter the housing 1. The air inside the housing 1 can be discharged through the exhaust vent under pressure. Through the above bottom-up air intake path, the principle of gravity settling can be used to pre-separate particulate impurities before the air enters the system, reducing the load on the mesh plate 16 and the dehumidifying plate 17 and extending their service life. In specific implementation, to achieve the aforementioned gravity settling pre-separation effect, the matching relationship between the total area of ​​the air inlet and the rated air volume of the air conditioner follows the following principles: Under the maximum air volume condition of the air conditioner, the airflow velocity at the air inlet should have a safe upper limit (e.g., it is recommended not to exceed 2.0 m / s), so that particles are difficult to be carried by when the airflow changes direction, and thus settle at the air inlet to ensure the effectiveness of gravity settling. In addition, the lower edge of the air inlet should be lower than the lowest point of the air inlet duct 14, that is, a safety height difference of at least 50 mm should be reserved to form a natural settling area, which is convenient for the accumulation of impurities and subsequent maintenance and cleaning. The mesh plate 16... Specifically, it can be a metal mesh or a nylon filter, and its mesh size can be selected according to the particle size distribution in the environment, usually 20 mesh to 100 mesh. The dehumidification plate 17 can be made of adsorption materials such as silica gel, molecular sieve or activated alumina, and its shape can be a honeycomb plate or filled with a granular layer to increase the contact area. The air conditioner 13 is an integrated air conditioning unit, and its cooling and heating capacity should be matched and calculated according to the heat generation inside the container and the external ambient temperature. As for the connection between the outer shell 12 and the top of the container 1, welding or bolt fixing can be used, and a sealing gasket is set at the connection to prevent rainwater from seeping in.

[0025] Please see Figure 4 As shown, the air intake units are a pair and arranged symmetrically; the air intake end of the air conditioner 13 is connected to a pair of air intake pipes 14 simultaneously through the first three-way pipe 2, and the first three-way pipe 2 is configured to selectively conduct at least one of the air intake pipes 14. By setting up two sets of symmetrical air inlet pipes 14 and mesh panels 16, redundancy can be formed. The air conditioner 13 is connected to the two air inlet pipes 14 respectively through the first three-way pipe 2. During normal operation, the first three-way pipe 2 can simultaneously conduct the two air inlet pipes 14 to maximize the air intake. When the dehumidification plate 17 or mesh panel 16 in one of the air inlet pipes 14 is blocked or malfunctions, it can be switched through the first three-way pipe 2 to only conduct the normal air inlet pipe 14 on the other side. The faulty side can be maintained without stopping the machine. In specific implementation, the first three-way pipe 2 can be an electric three-way valve or a valve group consisting of two independent valves. The method for detecting the fault of the mesh plate 16 can be a differential pressure sensor installed in the air inlet pipe 14 to monitor the pressure difference between the two ends of the mesh plate 16. When the pressure difference exceeds the preset value, the controller can determine the fault of the circuit and perform switching. The method for detecting the fault of the dehumidification plate 17 can be to install a humidity sensor at the end of the dehumidification plate 17 to monitor the real-time humidity of the air after dehumidification. When the humidity exceeds the preset value, the controller can also determine the fault and perform switching.

[0026] Please see Figures 4 to 7 As shown, the air inlet duct 14 is internally fixed with a partition 33 that penetrates the dehumidification plate 17, and externally has an adjustment mechanism. The partition 33 divides the interior of the air inlet duct 14 into a first air path and a second air path. The dehumidification plate 17 is slidably fitted with the air inlet duct 14 and the partition 33. The adjustment mechanism is configured to control the dehumidification plate 17 to selectively be located in the first air path or the second air path. The output end of the hot air blower 3 is connected to the second air path in each air inlet duct 14 through a second three-way pipe 32, and is used to deliver hot air to the second air path to perform thermal regeneration of the dehumidification plate 17. The first air path is the normal operating path, connecting the air inlet on the outer casing 12 and the air inlet of the air conditioner 13. The second air path is a dedicated regeneration path, connecting the output of the hot air blower 3. The specific distribution of the first and second air paths is as follows: the air inlet pipe 14 has a rectangular cross-section, and the partition plate 33 is integrally formed on both sides of its internal central axis along the length of the air inlet pipe 14, dividing the air inlet pipe 14 into parallel first and second air paths. A through groove is formed in the middle of the partition plate 33 and inside the air inlet pipe 14 along the width direction. The edge of the dehumidifying plate 17 is embedded in the groove and can slide back and forth along the groove. This allows the dehumidifying plate 17 to switch between the first and second air paths through the adjustment mechanism. When the dehumidifying plate 17 is in the first air path (refer to...), Figure 6 As shown), it can absorb moisture from the air inlet to complete the normal dehumidification function. When the dehumidification plate 17 is saturated, it can be switched to the second air path through the adjustment mechanism (the sliding direction of the dehumidification plate 17 can be referenced). Figure 6(in the direction of the middle arrow), then the hot air blower 3 can be started and hot air can be output. The hot air can enter the second air path in the air inlet pipe 14 through the second three-way pipe 32. After the hot air passes through the dehumidification plate 17, it can heat the adsorption material, so that the adsorbed water vapor is carried away by the hot air, thereby realizing the regeneration of the dehumidification plate 17. After the regeneration is completed, the dehumidification plate 17 can be switched to the first air path through the adjustment mechanism to restore the dehumidification function. In specific implementation, the second three-way pipe 32 can be equipped with an electrically controlled valve and connected to the second air passages in the two air inlet pipes 14 respectively, so that hot air can be delivered to the second air passage on either side as needed. The dehumidifying plate 17 is preferably made of zeolite molecular sieve, which has high thermal stability and adsorption capacity, and can be completely regenerated under hot air conditions of 150℃-250℃. The regeneration temperature is much lower than that of materials such as silica gel, which helps to reduce regeneration energy consumption. A slide rail or roller can be installed between the dehumidifying plate 17 and the air inlet pipe 14 to achieve smooth sliding. A sealing element, such as a rubber sealing strip, should be installed on the surface of the dehumidifying plate 17 at the sealing surface corresponding to the air inlet pipe 14 to improve the sealing performance of the dehumidifying plate 17 at both positions. The airtightness between the pipes 14 and the air inlet of the hot air blower 3 can also be achieved by setting a mesh plate 16 with the opening facing downwards to achieve dual filtration of gravity separation and physical screening. In order to avoid the impact of heat on the equipment inside the outer shell 12 and the sensors inside the air inlet pipe 14 during hot regeneration, a composite ceramic fiber heat insulation layer should be installed on the inner wall of the partition 33 and the outer side of the air inlet pipe. In addition, the output hot air temperature of the hot air blower 3 should be matched with the material of the dehumidification plate 17. If it is the zeolite molecular sieve mentioned above, the regeneration temperature should be controlled at 180℃-220℃, that is, it should be lower than the short-term temperature resistance limit of the air inlet pipe 14 and the partition 33. It is recommended that the regeneration cycle be triggered when the relative humidity of the air after dehumidification is continuously higher than the set value, and the regeneration time should be controlled at 20-30 minutes.

[0027] Please see Figure 6 As shown, the adjustment mechanism includes a first power source fixedly installed at the top of the air inlet pipe 14, and a push rod 4 fixedly installed at the output end of the first power source; a connecting rod 42 is rotatably provided between the push rod 4 and the dehumidification plate 17. The first power source (preferably an electric push rod) is installed on the housing of the air inlet duct 14. For example, when the dehumidification plate 17 needs to switch from the first air path to the second air path, the controller sends a signal to drive the first power source to start. Its output end pulls the push rod 4 upward and deflects the connecting rod 42. The connecting rod 42 can pull the dehumidification plate 17 to slide until the dehumidification plate 17 is completely in the second air path and stops. At this time, the regeneration operation can be performed. The recovery operation is the same. In practice, the first power source should have a self-locking function to prevent the dehumidification plate 17 from being accidentally displaced due to airflow impact.

[0028] Please see Figures 6 to 8As shown, a first diffuser ring 5 is provided at the connection between the partition 33 and the second air duct; a second diffuser ring 52 is fixedly provided on the inner wall of the first diffuser ring 5, and both the first diffuser ring 5 and the second diffuser ring 52 are horn-shaped structures. The first diffuser ring 5 and the second diffuser ring 52 can be assembled in a coaxial and concentric nested manner. Specifically, the first diffuser ring 5 is fixedly installed on the inner wall of the inlet section of the second air passage, with its large opening facing the dehumidifier plate 17 to be regenerated. The second diffuser ring 52 is fixedly installed inside the first diffuser ring 5, with its large opening facing the same direction as the first diffuser ring 5. The two constitute a two-stage diffusion structure. That is, the first diffuser ring 5 can diffuse the hot air entering the second air passage into an annular airflow, while the second diffuser ring 52 further diffuses and guides the airflow in the central region of the aforementioned annular airflow, forcing the hot air to flow toward the dehumidifier plate 17 in a scattering manner, thereby increasing the flow path of the hot air in the second air passage and the contact area with the dehumidifier plate 17. In addition, considering the increased wind resistance of the above-mentioned guiding structure, both the first diffuser ring 5 and the second diffuser ring 52 can be made of thin-walled metal stamping, with a thin wall thickness. While effectively diffusing the airflow, the resistance coefficient of the airflow is also negligible.

[0029] Please see Figures 6 to 9 As shown, the second air passage is provided with an exhaust port 6 and a one-way valve assembly at the end. The exhaust port 6 is connected to the first air passage and is inclined. The one-way valve assembly is configured to allow the airflow after heat regeneration to flow unidirectionally through the exhaust port 6 to the first air passage. During the regeneration process, the hot air flows through the dehumidifying plate 17 and becomes humid and hot exhaust gas carrying water vapor. This exhaust gas is not directly discharged into the atmosphere but is discharged to the first air path through the one-way valve assembly and the exhaust port 6. Since the air inlet pipe 14 is in a cut-off state at this time, and the exhaust port 6 is set at an angle with its end facing the mesh plate 16, specifically, the axis of the exhaust port 6 is set at a certain angle (generally 30°-60°) with the surface of the mesh plate 16 (i.e., the horizontal line). This ensures that the regeneration exhaust gas is blown obliquely from inside the second air path onto the surface of the mesh plate 16 to perform reverse sweeping of the mesh plate 16, remove impurities on the outside of the mesh plate 16, and make full use of the remaining regeneration exhaust gas. The kinetic energy and one-way valve assembly ensure that external airflow will not flow back into the second air path when the air inlet duct 14 is in normal operation, reducing the energy consumption generated by the airflow in the air inlet duct 14 flowing from the first air path to the second air path. Considering that residual heat energy may exist in the regenerated waste gas, causing the temperature of the mesh plate 16 to rise during backflushing, the air inlet duct 14 on this side can be naturally cooled for a period of time after regeneration before being reconnected to the air conditioner 13. With the above settings, this application can effectively utilize the hot air energy generated by the hot air blower 3, that is, the heat energy of the hot air is used for the thermal regeneration of the dehumidification plate 17, and the kinetic energy of the hot air is used for backflushing and cleaning the mesh plate 16.

[0030] Please see Figure 7As shown, the one-way valve assembly includes a flap 7 and a baffle 72, wherein the flap 7 is rotatably disposed inside the air inlet pipe 14, and the baffle 72 is fixedly disposed on the top of the inner wall of the air inlet pipe 14 and disposed on the opening path of the flap 7. The flap 7 can be kept in the closed position, i.e., vertical state, and the valve port can be sealed by the torsion spring. When the regeneration airflow flows from upstream to the flap 7, the airflow pressure acts on the flap 7 and can overcome gravity or spring force to push it open. At this time, exhaust gas is allowed to pass through. The baffle 72 is set on the opening path of the flap 7 to limit its maximum opening angle (such as limiting it to the range of 15°-30°) in order to shorten the reset distance of the flap 7, thereby shortening the corresponding time for the flap 7 to reset and sit down. In practice, the flap 7 achieves a seal under normal conditions through a torsion spring. Specifically, when a torsion spring is used, the flap 7 relies on the torsion spring installed at the rotating shaft to generate a pre-tightening torque (generally 0.05 N·m to 0.2 N·m, which is sufficient to ensure that the flap remains closed when the air inlet pipe is working normally). In addition, a heat-resistant silicone sealing ring is provided around the flap 7 facing the valve seat to form a contact seal with the valve seat. This ensures that when the first air passage of the air inlet pipe 14 is in normal air intake, the airflow direction is consistent with the closing direction of the flap 7, and the aerodynamic force can further press the flap 7, thereby ensuring the airtightness of the flap 7 when the air inlet pipe 14 is working normally.

[0031] Please see Figure 2 and Figure 10 As shown, the exhaust port includes an air outlet 8, which is located in the upper part of the side wall of the housing 1. By setting the air outlet 8 in the upper part of the side wall of the box 1, which is high above the ground, the possibility of rainwater splashing in through the road is extremely low. Even if a little rainwater approaches the air outlet 8 due to the wind, the positive pressure formed by the continuous exhaust at the air outlet 8 makes it difficult for the rainwater to enter the interior of the box 1.

[0032] Please see Figure 10 As shown, a rain cover 9 is fixedly installed on the outer wall of the housing 1 on the outer side of the air outlet 8; the bottom of the side wall of the rain cover 9 is arc-shaped. The bottom of the rain cover 9 is open to guide the air discharged from the air outlet 8. The rain cover 9 provides additional physical protection for the air outlet 8, which can further reduce the situation where rainwater directly enters the air outlet 8. When rainwater falls from above onto the rain cover 9, it flows down along the outer wall of the rain cover 9 under the action of gravity. The curved surface can change the direction of the water flow, making it further away from the air outlet 8.

[0033] Please see Figure 5 and Figure 10 As shown, both the bottom edge of the outer shell 12 and the bottom edge of the rain cover 9 are fixedly provided with guide plates 10 to guide water droplets away from the edge surface. The cross-sectional shape of the deflector 10 is similar to an acute angle, with its outer side extending downward and its inner side being inclined. This allows water to tend to gather at the bottom of the deflector 10 when it flows at the bottom edge of the housing 12 or the rain cover 9, rather than spreading to the bottom, so that the rainwater can drip off and be discharged as quickly as possible. In summary, the switching of the air inlet unit and the hot regeneration of the dehumidifier plate 17 in this application can be based on a PLC intelligent control system, which mainly includes the following sensors: differential pressure sensor, humidity sensor, temperature sensor, and position sensor. The differential pressure sensor is installed at both ends of each mesh plate 16 to detect the degree of blockage of the mesh plate 16. The humidity sensor is installed on the air outlet side (in the first air path) of each dehumidifier plate 17 to detect the relative humidity of the air after dehumidification. The temperature sensor is installed in each second air path and at the air inlet of the air conditioner 13 to monitor the regeneration temperature and the air conditioner inlet temperature. The position sensor is installed at both ends of the sliding path of each dehumidifier plate 17 to confirm whether the dehumidifier plate 17 is located in the first air path or the second air path. The operating sequences for each major working condition are as follows: Normal operating conditions: The first three-way pipe 2 and the two air inlet pipes 14 are all open, the dehumidification plates 17 are all located in the first air duct, the hot air blower 3 is closed, and the air conditioner 13 draws air from both sides at the same time. Single-sided mesh plate 16 blockage condition: When the differential pressure sensor on one side exceeds the limit, the PLC controls the valve of the first three-way pipe 2 to be cut off on that side, the hot air blower 3 is turned off, the dehumidification plate 17 is maintained in the first air path, and maintenance personnel can replace the mesh plate 16 online, while the other side continues to work. Single-sided dehumidifier plate 17 saturation condition: When the humidity sensor on one side reports that the air humidity after dehumidification continuously exceeds the preset value, the PLC can execute the following sequence: First, the valve on the first three-way pipe 2 is shut off, and the valve on the second three-way pipe 32 is opened. Then, the adjusting mechanism drives the dehumidifying plate 17 on this side to slide from the first air passage to the second air passage. Subsequently, the hot air blower 3 is started and delivers hot air to the second air passage on this side through the second three-way pipe 32 for a certain period of time. Then, the regeneration exhaust gas enters the first air passage through the one-way valve assembly and blows the mesh plate 16 from the inside. As the above regeneration ends, the hot air blower 3 is turned off. After a certain period of time, the components in the second and first air passages, such as the mesh plate 16, are cooled. Finally, the dehumidifying plate 17 switches to the first air passage, while the valve on the first three-way pipe 2 is opened and the valve on the second three-way pipe 32 is closed, thus restoring normal operation.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
