Detailed ways

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary, and are intended to explain the present invention and should not be construed as limiting the present invention.

FIG. 1 is a centralized exhaust method applied to a large-scale energy storage system according to an embodiment of the present invention. The method includes the following steps:

Step 101, set a first temperature smoke alarm system, a control system and a first fire extinguishing system inside the battery energy storage container; set up an exhaust system and an exhaust gas treatment system, set an air inlet for the exhaust system, and connect the air inlet to the battery energy storage container Internally, the air outlet of the exhaust system is connected to the exhaust gas treatment system.

Step 102 , monitor the energy storage battery clusters arranged in the battery energy storage container through the first temperature smoke alarm system arranged in the battery energy storage container.

Step 103 , if the first temperature smoke alarm system detects that the temperature of the energy storage battery cluster is higher than a preset temperature, or when smoke is generated in the battery energy storage container, an alarm signal is sent to the control system.

Step 104, the control system controls the first fire extinguishing system to extinguish fire, and simultaneously controls the activation of the exhaust system and the exhaust gas treatment system, and discharges the exhaust gas generated by the first fire extinguishing system to the exhaust gas treatment system through the exhaust system.

The present invention takes a 600MW/1200MWh scale lithium iron phosphate battery energy storage power station as an example to illustrate. As a large-scale energy storage system, the capacity of each battery energy storage container is 3MW/6MWh, then the large-scale energy storage system of the large-scale energy storage system has a capacity of 3MW/6MWh. The large-scale energy storage power station has a total of 200 battery energy storage containers. The structure of the overall large-scale energy storage system is shown in Figure 2.

Each battery energy storage container is equipped with a first temperature smoke alarm system, including a temperature sensor system 3 and a smoke sensor system 5 . The temperature sensing system 3 is installed between each energy storage battery cluster 2 , detects the internal ambient temperature of the battery energy storage container 1 in real time, and sends the temperature signal to the control system 6 in real time. In the first temperature smoke alarm system, the temperature sensing system 3 sets an alarm temperature, for example, it is set to send an alarm signal when the temperature sensing system 3 detects that the ambient temperature is greater than 70°C. The smoke detection system 5 is installed above the battery cluster, detects the concentration of combustible gas in the battery energy storage container 1 in real time, such as the concentration of combustible gases such as CO and H ₂ , and sends the signal of the concentration of combustible gas to the control system 6 in real time. When its concentration is greater than the preset alarm concentration, an alarm signal is sent. When one of the temperature sensing system 3 or the smoke sensing system 5 reaches the alarm level, or both reach the alarm level at the same time, an alarm signal is sent to the control system 6 .

When receiving the alarm signal, the control system 6 sends out a linkage command to immediately cut off the connection between the alarmed battery energy storage container 1 and the entire energy storage power station, stop the charging and discharging action of the battery energy storage container 1 and cut off all power supplies to prevent the inside of the container. An electrical spark occurred causing an explosion. At the same time, the first fire extinguishing system 4 is activated, for example, perfluorohexanone fire extinguishing agent is used to spray the ignition point at a fixed point to extinguish the fire. At the same time, the signal valve 7 set on the exhaust duct of the exhaust system is opened and the exhaust system is activated, and the combustible gas generated in the battery energy storage container 1 is uniformly transported to the exhaust gas treatment through the fan 9 and the exhaust duct 8 of the exhaust system. The system 10 prevents flammable gas from accumulating in the battery energy storage container 1 to cause secondary explosion. When the detection signals of the temperature sensing system 3 and the smoke sensing system 5 are lower than the alarm level, the signal valve 7 is closed.

Each battery energy storage container 1 has a separate air exhaust system signal valve 7. When a fire occurs in one battery energy storage container 1, the battery energy storage container 1 is powered off and extinguished and exhausted without affecting other battery storage containers 1. The normal operation of the battery energy storage container. When a fire occurs in multiple battery energy storage containers, the exhaust system will be opened one by one according to the pressure of the exhaust duct 8. The battery energy storage container 1 that fires first will be exhausted first, and the battery energy storage container that fires later will be exhausted. After the pressure of the exhaust duct is reduced, open the exhaust signal valve 7 to exhaust the air to prevent the exhaust duct 8 from bursting due to excessive pressure, and also prevent the combustible gas between different battery energy storage containers 1 from collusion with each other.

The battery energy storage container 1 is connected to the exhaust gas treatment system 10 through the exhaust duct 8. The exhaust gas treatment system 10 is provided with an exhaust gas combustion device 11, and the exhaust gas combustion device 11 can burn the combustible gas generated after the battery energy storage container 1 fires. . After the exhaust system is turned on, the waste gas treatment system 10 automatically turns on the waste gas combustion device 11, and the waste gas combustion device 11 can be adjusted according to the size of the exhaust gas flow to ensure that the waste gas is fully burned. The exhaust gas after combustion is discharged into the air through the exhaust filter device 12 to ensure the safety and environmental protection of the exhaust gas. In addition, the exhaust gas treatment system 10 is provided with a second smoke and temperature alarm system 13 and a second fire extinguishing system 14. Once the exhaust gas is not completely burned and discharged, there is a flammable gas leakage, or the alarm temperature is reached, the fire extinguishing system will be activated to spray perfluorohexane Ketone fire extinguishing agent to ensure the safety of waste gas treatment process.

The exhaust duct 8 in the exhaust system plays an important role, and can timely remove the combustible gas when a fire occurs in the battery energy storage container 1 . When the combustible gas encounters the flame retardant, it may burn or even explode. Therefore, the exhaust duct 8 needs to maintain an inert environment for a long time or be filled with low oxygen content gas to ensure the safety of the combustible gas transmission. In addition, the exhaust duct 8 needs to have good airtightness and good pressure bearing, so as to avoid the leakage of flammable gas and the discharge of a large amount of flammable gas from causing the pipe to burst.

The exhaust gas treatment system 10 is arranged at the center of the energy storage power station, and the transmission distance of the combustible gas in the exhaust duct 8 is shortened as much as possible. When the scale of the energy storage power station is relatively large, multiple exhaust gas treatment systems 10 can be installed according to the actual situation to ensure the safety and timeliness of the exhaust gas during the transmission process.
