[0046] The core of the present application is to provide a contaminated water treatment method, a contaminated water treatment device and an energy storage system to reduce water pollution.

[0047] In order to enable those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in conjunction with the drawings and embodiments.

[0048] Please refer to Figures 1 to 4 .

[0049] In one specific embodiment, the contaminated water treatment method provided by the specific embodiment of the present application comprises the step of collecting waste water at an electrical appliance position. Specifically, the waste water at the electrical appliance position is collected, wherein the collection of waste water at the electrical appliance position can flow to a predetermined position under the action of gravity of the waste water itself, or pumped to the predetermined position by a pump body.

[0050] Specifically, the electrical appliance installed at the electrical appliance position can be an energy storage device 100, a power device, etc. For example, Figure 1 As shown, when the energy storage device 100 is working normally, the internal substances will not be discharged. When the battery cell in the energy storage device 100 is out of control, the water fire-fighting spray water equipped in the battery compartment will mix with the pollutants of the battery cell electrolyte to form contaminated fire-fighting water, at this time, the fire-fighting water will overflow from the door gap 102 of the housing 101 of the energy storage device 100 and the position of the ventilation device 103, wherein the ventilation device 103 can be a fire-fighting ventilation device or a ventilation device.

[0051] When the electrical appliance is operating normally, the wastewater from its location is discharged into drainage ditch 400, which is connected to external drainage equipment. This process does not involve waste material pollution and requires no purification. "Once the appliance is operating normally" means the appliance is undamaged and its internal components have not mixed into the wastewater at its location. The wastewater from the appliance's location can be rainwater falling on it or water sprayed onto it, which does not require purification.

[0052] When substances from the electrical appliances mix with the wastewater from the appliance's location, the wastewater from that location is discharged into a sewage collection device. At this point, the wastewater from the appliance's location may contain substances from the electrical appliances.

[0053] As described above, in the wastewater treatment method provided in the specific embodiments of this application, when the electrical appliance is working normally, the wastewater flowing through the appliance location is usually rainwater or clean water, which does not contain pollutants. In this case, the wastewater from the appliance location can be directly discharged into the drainage ditch 400. However, when substances from the electrical appliance are mixed into the wastewater at the appliance location, the wastewater is discharged into a sewage collection device to prevent substances from the electrical appliance from being discharged through the drainage ditch 400, thereby reducing water pollution.

[0054] In one specific implementation, after the wastewater collection device completes the wastewater collection, it can send the wastewater to a designated location for purification by a purification device.

[0055] In another specific embodiment, the wastewater entering the wastewater collection device is purified by a purification device within the wastewater collection device. In this case, the purified wastewater can be directly discharged through the drainage ditch 400. The wastewater purification process involves selecting appropriate purification equipment based on the required purifying substances; this application does not impose specific limitations.

[0056] In one specific embodiment, the polluted water treatment device provided by this invention is used to implement the above-described polluted water treatment method. The polluted water treatment device includes a foundation 200, a valve assembly, a polluted water collection device 300, and a first drainage channel 500. The valve assembly is used to control the flow direction of the water discharged from the discharge tank.

[0057] In one specific embodiment, the polluted water treatment device further includes a controller connected to electrical equipment to receive the operating status of the electrical equipment, and connected to a valve assembly to control the opening and closing of the valve assembly. For example, the controller can determine whether the electrical equipment is operating normally or whether substances inside the electrical equipment have mixed into the wastewater at the location of the electrical equipment.

[0058] The foundation 200 includes a base 203, with a support platform 201 on its upper surface. The base 203 has a drainage groove 204 with an open top. Specifically, the drainage groove 204 can be located on one side of the support platform 201. In use, the foundation 200 supports electrical appliances. During installation, the electrical appliances are mounted on the support platform 201. The surface of the support platform 201 where the electrical appliances are mounted is preferably flat, but it can also be a mounting bracket adapted to the electrical appliances.

[0059] The wastewater collection device can be connected to the drainage tank 204 to collect wastewater from the electrical appliance location. Specifically, when the wastewater collection device needs to collect wastewater, it is connected to the drainage tank 204. When wastewater collection is not required, the wastewater collection device is isolated from the drainage tank 204, and the water in the wastewater tank is directly discharged into the drainage ditch 400 through the first drainage pipe.

[0060] The first drainage channel 500 can be connected to the drainage trough 204 to collect wastewater from the electrical appliance location, and the first drainage channel 500 discharges the wastewater from the electrical appliance location to the drainage ditch 400. The first drainage channel 500 can be a pipe structure.

[0061] like Figure 2 As shown, in one specific embodiment, the polluted water treatment device further includes a second drainage channel 600. The valve assembly includes a first valve body 800 and a second valve body 700, and the two ends of the second drainage channel 600 are respectively connected to the polluted water collection device 300 and the outlet 205 of the drainage tank 204. Specifically, the first drainage channel 500 and the second drainage channel 600 can both be connected to the outlet 205 of the drainage tank 204; or, the inlets of the first drainage channel 500 and the second drainage channel 600 can be connected to the outlet 205 of the drainage tank 204 through a T-connector.

[0062] A first valve body 800 is disposed in a first drainage channel 500, with its two ends connected to the outlets 205 of a drainage ditch 400 and a drainage trough 204, respectively. A second valve body 700 is disposed in a second drainage channel 600. Both the first valve body 800 and the second valve can be manual or electric valves, etc.

[0063] Specifically, during use, the energy storage device 100 is installed on the support platform 201 of the foundation 200; under normal conditions, the second valve body 700 is always closed and the first valve body 800 is always open. When it rains, the rainwater collected is discharged into the ordinary drainage ditch 400 through the first drainage channel 500.

[0064] If thermal runaway occurs in the battery cell of the energy storage device 100, the first valve body 800 and the second valve body 700 are linked to the thermal runaway via manual or electric means. Specifically, the second valve body 700 opens and the first valve body 800 closes; then the polluted water is discharged into the polluted water collection device 300 through the second drainage channel 600. After the polluted water is collected by the polluted water collection device 300, it is discharged through the second valve body 700, and then the entire second valve body 700 is sent to a specialized sewage treatment plant for treatment.

[0065] The first valve body 800 and the second valve body 700 can be manually controlled by the operator. Specifically, the first valve body 800 and the second valve body 700 can be controlled on-site or remotely.

[0066] The controller is a first valve body controller. The first valve body 800 and the second valve body 700 are signal-connected to the first valve body controller. Specifically, the first valve body controller can be signal-connected to the thermal runaway monitoring equipment of the energy storage device 100. Under normal conditions of the energy storage device 100, when the first valve body controller does not receive a thermal runaway signal from the thermal runaway monitoring equipment, it controls the first valve body 800 to open and the second valve body 700 to close. When the first valve body controller receives a thermal runaway signal from the thermal runaway monitoring equipment, it controls the first valve body 800 to close and the second valve body 700 to open, reducing the workload of the staff.

[0067] like Figure 3 As shown, in one specific embodiment, the polluted water treatment device further includes a second drainage channel 600 and a third drainage channel 900. The valve assembly includes a second valve body 700 and a third valve body 1100. The two ends of the second drainage channel 600 are respectively connected to the outlets 205 of the polluted water collection device 300 and the drainage trough 204. The second valve body 700 and the third valve body 1100 can be manually controlled by operators to open and close. Specifically, the opening and closing of the second valve body 700 and the third valve body 1100 can be controlled on-site or remotely. The polluted water collection device 300 is specifically detachable.

[0068] The second valve body 700 is installed in the second drainage channel 600. The two ends of the third drainage channel 900 are respectively connected to the outlet 205 of the polluted water collection device 300 and the drainage trough 204; the two ends of the first drainage channel 500 are respectively connected to the drainage ditch 400 and the outlet of the polluted water collection device 300. The third valve body 1100 is installed in the third drainage channel 900.

[0069] Under normal conditions, when the energy storage device 100 is operating normally or the polluted water collection device 300 has completed its purification operation, both the second valve body 700 and the third valve body 1100 remain open. Rainwater collected during rainfall is discharged into the sewage collection device through the second drainage channel 600, and then into the ordinary drainage ditch 400 through the third drainage channel 900. When a battery cell experiences thermal runaway, the third valve body 1100 is manually or electrically linked to the thermal runaway and shut off. Once the polluted water collection is complete, the second valve body 700 is closed, and the third valve body 1100 remains closed, allowing the entire polluted water collection device 300 to be transported to a specialized sewage treatment plant for further processing.

[0070] To reduce the workload of staff, the controller is the second valve body 700 controller, and the third valve body 1100 is signal-connected to the second valve body 700 controller. When substances inside the electrical appliance are mixed into the wastewater at the appliance location, the third valve body 1100 controls the second valve body 700 to close. Under normal conditions of the energy storage device 100, when the first valve body controller does not receive a thermal runaway signal from the thermal runaway monitoring device of the energy storage device 100, the second valve body 700 controller controls the second valve body 700 and the third valve body 1100 to open. When substances inside the electrical appliance are mixed into the wastewater at the appliance location, the second valve body 700 controller controls the second valve body 700 to open and the third valve body 1100 to close.

[0071] like Figure 4 As shown, in one specific embodiment, the polluted water treatment device further includes a third drainage channel 900 and a third valve body 1100. The two ends of the third drainage channel 900 are respectively connected to the outlet 205 of the polluted water collection device 300 and the drainage trough 204. At this time, the drainage trough 204 is always in communication with the polluted water collection device 300.

[0072] The first drainage channel 500 is connected at both ends to the drainage ditch 400 and the first outlet of the polluted water collection device 300, respectively. The polluted water collection device 300 is provided with a second outlet that is independently set from the first outlet. The polluted water collection device 300 is equipped with a purification device. The purification device may be selected according to the need for purification substances, and this application does not make specific limitations.

[0073] The third valve body 1100 is installed in the third drainage channel 900. The third valve body 1100 can be opened and closed manually by the operator. Specifically, the third valve body 1100 can be opened and closed on-site or remotely.

[0074] Under normal conditions, the third valve 1100 does not receive a thermal runaway signal from the thermal runaway monitoring device of the energy storage device 100, and therefore remains open. Rainwater collected during rainfall is discharged through the second drainage channel 600 into the polluted water collection device 300, and then into the ordinary drainage ditch 400. When a battery cell experiences thermal runaway, the third valve 1100 is manually or electrically closed in conjunction with the thermal runaway. After the polluted water collection is complete, the third valve 1100 is closed. The polluted water is then thoroughly purified by a purification device within the polluted water collection device 300 before being reopened and discharged.

[0075] To reduce the workload of staff, the controller also includes a third valve body controller, with the third valve body 1100 connected to the third valve body controller via signal connection. Specifically, the third valve body controller can be connected to the thermal runaway monitoring equipment of the energy storage device 100 via signal connection. Under normal conditions of the energy storage device 100, if the third valve body controller does not receive a thermal runaway signal from the thermal runaway monitoring equipment of the energy storage device 100, the third valve body controller controls the third valve body 1100 to open. When substances inside the electrical appliance are mixed into the wastewater at the location of the electrical appliance and purified by the purification device, if the third valve body controller receives a thermal runaway signal from the thermal runaway monitoring equipment of the energy storage device 100, the third valve body controller controls the third valve body 1100 to close, at which point the polluted water is retained in the polluted water collection device 300.

[0076] The purification device can use an adsorber or chemical reagents to combine pollutants in the polluted water, purifying it into qualified wastewater for discharge. This setup avoids the need for secondary treatment by the polluted water collection device 300.

[0077] like Figures 5 to 7 As shown, the foundation 200 also includes a vent cover 202, which covers the drainage ditch 204. The bottom of the drainage ditch 204 gradually decreases towards the outlet 205. Specifically, the vent cover 202 is detachably installed on the base 203 for easy cleaning. To facilitate timely passage of liquid through the vent cover 202, the vent cover 202 can be a grating plate.

[0078] like Figure 6 and Figure 7 As shown, the drainage channel 204 is arranged in a ring around the outer periphery of the support platform 201. Specifically, the drainage channel 204 is arranged in a ring.

[0079] like Figure 8As shown, in one specific embodiment, the polluted water treatment device further includes a manifold 1200. Multiple foundations 200 are provided, which can be arranged in rows or arrays. Each foundation 200 is equipped with an electrical device, or multiple foundations 200 can support the same electrical device. The outlets 205 of the drainage channels 204 in at least two foundations 200 are connected to the inlet of the first drainage channel 500 via the manifold 1200. Preferably, the outlets 205 of the drainage channels 204 in all foundations 200 are connected to the inlet of the first drainage channel 500 via the manifold 1200.

[0080] Specifically, when the electrical equipment is an energy storage device 100, the wastewater treatment device can treat the wastewater from the entire station. In the specific setup, each energy storage device 100 is first interconnected via a manifold 1200, and then connected to the first drainage channel 500. The third valve 1100 remains open under normal conditions for the energy storage devices 100, allowing rainwater to be discharged directly. Firefighting wastewater is purified by the wastewater treatment device and discharged into the station-level drainage ditch, which is connected to the ordinary drainage ditch 400 for direct water discharge.

[0081] To reduce water pollution, preferably, each energy storage device 100 is linked to the third valve body 1100. If any cell of the energy storage device 100 experiences thermal runaway, the feedback is sent to the third valve body controller, triggering the third valve body 1100 to close, thereby ensuring the collection and effective purification of fire-fighting wastewater.

[0082] Of course, the wastewater treatment device can control the operation of the corresponding valve assembly through the first valve body controller or the second valve body controller. The control logic has been described above and will not be repeated here.

[0083] The treatment measures and solutions for fire-fighting wastewater from energy storage systems have solved the environmental pollution problem caused by fire-fighting wastewater from current energy storage systems. Furthermore, the special design of the foundation 200 and the logic control strategy of the water valves ensure the timely collection and treatment of fire-fighting wastewater.

[0084] The energy storage system provided in this application also includes a wastewater treatment device and an energy storage device 100. The wastewater treatment device is any of the aforementioned wastewater treatment devices, and the energy storage device 100 is installed on the support platform 201 of the wastewater treatment device. The specific structure of the wastewater treatment device has been described above. This application includes the aforementioned wastewater treatment device and also has the aforementioned technical effects.
