Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
Fig. 1 is a centralized air exhaust method applied to a large-scale energy storage system according to an embodiment of the present invention. The method comprises the following steps:
step 101, arranging a first temperature smoke sensing alarm system, a control system and a first fire extinguishing system in a battery energy storage container; and an exhaust system and a waste gas treatment system are arranged, the exhaust system is provided with an air inlet, the air inlet is connected into the battery energy storage container, and an air outlet of the exhaust system is connected to the waste gas treatment system.
And 102, monitoring an energy storage battery cluster arranged in the battery energy storage container through a first temperature smoke sensing alarm system arranged in the battery energy storage container.
And 103, if the first temperature smoke sensing alarm system monitors that the temperature of the energy storage battery cluster is higher than the preset temperature or smoke is generated in the battery energy storage container, sending an alarm signal to the control system.
And 104, controlling the first fire extinguishing system to extinguish a fire by the control system, simultaneously controlling and starting the exhaust system and the waste gas treatment system, and discharging waste gas generated by fire extinguishment of the first fire extinguishing system to the waste gas treatment system through the exhaust system.
The invention is explained by taking a 600MW/1200MWh scale lithium iron phosphate battery energy storage power station as an example, and as a scale energy storage system, the capacity of each battery energy storage container is 3MW/6MWh, and the large scale energy storage power station of the scale energy storage system has 200 battery energy storage containers in total. The structure of the whole large-scale energy storage system is shown in figure 2.
A first temperature smoke sensing alarm system is arranged in each battery energy storage container and comprises a temperature sensing system 3 and a smoke sensing system 5. The temperature sensing system 3 is arranged among the energy storage battery clusters 2, detects the internal environment temperature of the battery energy storage container 1 in real time, and sends a temperature signal to the control system 6 in real time. The temperature sensing system 3 in the first temperature smoke sensing alarm system sets an alarm temperature, for example, the temperature sensing system 3 is set to send an alarm signal when detecting that the ambient temperature is more than 70 ℃. The smoke sensing system 5 is arranged above the battery cluster and detects the concentration of combustible gas such as CO and H in the battery energy storage container 1 in real time 2 And waiting for the concentration of the combustible gas, sending a signal of the concentration of the combustible gas to the control system 6 in real time, and sending an alarm signal if the concentration of the combustible gas is greater than the preset alarm concentration. When one of the temperature sensing system 3 or the smoke sensing system 5 reaches an alarm level or both the temperature sensing system and the smoke sensing system reach the alarm level, an alarm signal is sent to the control system 6.
The control system 6 sends out a linkage instruction when receiving the alarm signal, immediately cuts off the connection between the battery energy storage container 1 which alarms and the whole energy storage power station, stops the charging and discharging actions of the battery energy storage container 1 and cuts off all power supplies, and prevents the explosion caused by electric sparks in the container. At the same time, the first fire extinguishing system 4 is activated, for example, by using a perfluorohexanone fire extinguishing agent to perform a spot spray fire extinguishing. Meanwhile, a signal valve 7 arranged on an exhaust pipeline of the exhaust system is opened, the exhaust system is started, combustible gas generated in the battery energy storage container 1 is uniformly conveyed to a tail gas treatment system 10 through a fan 9 and an exhaust pipeline 8 of the exhaust system, and the combustible gas is prevented from being gathered in the battery energy storage container 1 to generate secondary explosion. When the temperature sensing system 3 and the smoke sensing system 5 detect that the signals are lower than the alarm level, the signal valve 7 is closed.
Each battery energy storage container 1 is provided with an independent exhaust system signal valve 7, when a fire disaster occurs to one battery energy storage container 1, the battery energy storage container 1 is subjected to power-off treatment and is subjected to fire extinguishing and exhaust, and the normal operation of other battery energy storage containers is not influenced. When a plurality of battery energy storage containers all have a fire, the exhaust system is opened one by one according to the pressure of the exhaust pipeline 8, the battery energy storage container 1 which has a fire firstly carries out exhaust treatment, the battery energy storage container which has a fire later carries out exhaust treatment after the pressure of the exhaust pipeline is reduced, the exhaust signal valve 7 is opened to exhaust air, the exhaust pipeline 8 is prevented from bursting due to overlarge pressure, and combustible gases among different battery energy storage containers 1 are prevented from being communicated with one another.
Battery energy storage container 1 passes through exhaust duct 8 and is connected to exhaust-gas treatment system 10, sets up exhaust gas combustion device 11 in exhaust-gas treatment system 10, and exhaust gas combustion device 11 can carry out the combustion processing with the combustible gas that battery energy storage container 1 produced after taking place the fire disaster. After the exhaust system is opened, the waste gas combustion device 11 is automatically opened by the waste gas treatment system 10, and the waste gas combustion device 11 can be adjusted according to the exhaust flow, so that the waste gas can be fully combusted. And the combusted tail gas is discharged to the air through the tail gas filtering device 12, so that the safety and the environmental protection of the discharged gas are ensured. In addition, a second smoke temperature sensing alarm system 13 and a second fire extinguishing system 14 are arranged in the waste gas treatment system 10, once waste gas is discharged due to incomplete combustion and combustible gas leaks or the temperature reaches an alarm temperature, the fire extinguishing system can be started to spray a perfluorohexanone fire extinguishing agent, and the safety of the waste gas treatment process is ensured.
The exhaust duct 8 in the exhaust system has an important function, and can timely discharge combustible gas when the battery energy storage container 1 is in a fire. However, the combustible gas may be burned or even exploded when encountering the flame retardant, so the exhaust duct 8 needs to maintain an inert environment for a long time or be filled with gas with low oxygen content, thereby ensuring the safety of the combustible gas during transportation. In addition, the exhaust duct 8 needs to have good air tightness and good pressure bearing performance, so that the duct is prevented from bursting due to leakage of combustible gas and discharge of a large amount of combustible gas.
The waste 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 large, a plurality of waste gas treatment systems 10 can be arranged according to actual conditions, and the safety and timeliness of waste gas in the transmission process are guaranteed.
In addition, as shown in fig. 3, the present invention provides a centralized air exhaust device applied to a large-scale energy storage system, comprising:
