Description

Technical Field

[0001] The present invention relates to the technical field of cooling and temperature reduction, and in particular to a UPS fire protection system. Background Art

[0002] An uninterruptible power supply (UPS) is a power protection device that uses batteries as energy storage devices and an inverter as its main unit to ensure stable voltage. Existing UPS battery cabinets typically incorporate fire detectors and fire extinguishers within the cabinet, forming a fire detector and fire extinguisher system to address potential battery fires within the UPS. This relatively simple automatic fire extinguishing system utilizes a fire detector that ruptures upon reaching a preset temperature. Due to the pre-set internal pressure, the fire extinguishing agent is released from the rupture, achieving point-to-point fire suppression.

[0003] When a fire breaks out, the fire detection tube ruptures due to the high temperature, spraying fire extinguishing agent from the rupture. However, battery fires are highly specific. Once the battery is short-circuited, overheated, or squeezed, it can generate a large amount of heat, triggering a chain reaction in the internal electrolyte and electrode materials, leading to thermal runaway and potentially large-scale explosions and fires. These fires are characterized by spontaneous combustion, easy reignition, rapid progression, and susceptibility to explosion, making them completely different from ordinary fires. UPS battery cabinets are particularly numerous and large-capacity, making it very easy for the fire extinguishers in each cabinet to fail to extinguish the fire, or for the fire to reignite after being extinguished.

[0045] Figure 1is a structural schematic diagram of a UPS fire extinguishing system provided by an embodiment of the present application; Figure 2 is a structural block diagram of a UPS fire extinguishing system provided by an embodiment of the present application.

[0046] The existing UPS fire extinguishing system adopts a fire detection tube and a fire extinguisher. The storage capacity of the fire extinguisher is limited. When a fire occurs in a battery cabinet, it cannot cover every area. Moreover, the shelf life of the fire extinguisher is limited, and it needs to be replaced every year. For military, nuclear power, data center and other application scenarios, it may involve security issues, which makes the cost of later maintenance higher. Moreover, the fire detection tube is manually arranged by artificial, and the arrangement position of the fire detection tube may deviate from the position where the fire occurs, which affects the fire extinguishing effect.

[0047] As shown in Figure 1 An embodiment of the present application provides a UPS fire extinguishing system, which comprises:

[0048] a plurality of UPS battery cabinets 1;

[0049] a plurality of fire detection mechanisms 2, at least one fire detection mechanism 2 is arranged in each UPS battery cabinet 1, which is used for detecting whether a fire occurs in the corresponding UPS battery cabinet 1 and outputting a corresponding detection signal;

[0050] a supply and recovery mechanism 3, which is connected with each UPS battery cabinet 1 through a supply pipeline 301 and a recovery pipeline 302, and is used for performing a corresponding fire extinguishing operation on the corresponding UPS battery cabinet 1 according to the detection signal.

[0051] In the embodiment, the UPS fire extinguishing system of the present application is provided with a supply and recovery mechanism 3, which is connected with each UPS battery cabinet 1 through a supply pipeline 301 and a recovery pipeline 302, and is used for providing a fire extinguishing agent to the corresponding UPS battery cabinet 1 through the supply pipeline 301 and extracting the smoke in the corresponding UPS battery cabinet 1 through the recovery pipeline 302 when the fire detection mechanism 2 detects that a fire occurs in the UPS battery cabinet 1, and recovering the fire extinguishing agent from the smoke, so as to continuously supply the fire extinguishing agent to the UPS battery cabinet 1, ensure that the fire in the battery cabinet can be extinguished, effectively avoid the situation that the fire reignites after being extinguished, and further reduce the possibility that the battery module in the UPS battery cabinet 1 explodes. Moreover, the supply and recovery mechanism can extract the smoke in the UPS battery cabinet 1, continuously drive the air in the UPS battery cabinet 1, isolate the battery module and oxygen, and reduce the possibility that a fire and explosion occur in the UPS battery cabinet 1. It can be applied to important fields such as subways, airports, aerospace, military industry and data centers. The plurality of UPS battery cabinets 1 and the supply and recovery mechanism 3 are separately arranged in the same space or different spaces, which is convenient for maintenance.

[0052] Specifically, the fire detection mechanism 2 can use a fire detector, and can also use a smoke detection sensor, a temperature detection sensor, a gas detection sensor, etc., which are arranged at different positions inside the UPS battery cabinet 1. When a fire occurs inside the UPS battery cabinet 1, the fire detector (or the smoke detection sensor, the temperature detection sensor, and the gas detection sensor) converts the characteristic physical quantity of the fire, such as temperature, smoke, gas, and radiant light intensity, into an electrical signal as the detection signal.

[0053] Preferably, the supply and recovery mechanism 3 comprises:

[0054] The fire control controller 4 is electrically connected to each fire detection mechanism 2, and is configured to output a fire extinguishing agent release instruction and a smoke recovery instruction according to a fire detection signal from the fire detection mechanism 2, and output a stop fire extinguishing instruction according to a no-fire detection signal from the fire detection mechanism 2.

[0055] The fire extinguishing operation mechanism is configured to release the fire extinguishing agent to the corresponding UPS battery cabinet 1 through the supply pipeline 301 according to the fire extinguishing agent release instruction, perform smoke recovery on the corresponding UPS battery cabinet 1 through the recovery pipeline 302 according to the smoke recovery instruction, and stop performing the release of the fire extinguishing agent and the recovery of the smoke according to the stop fire extinguishing instruction.

[0056] Specifically, the automatic control of the UPS fire extinguishing system is realized by arranging the fire control controller 4. When the fire detection mechanism 2 detects that a fire occurs inside the corresponding UPS battery cabinet 1, the fire detection mechanism 2 sends a fire detection signal to the fire control controller 4. The fire control controller 4 generates and outputs corresponding fire extinguishing agent release instructions and smoke recovery instructions according to the received fire signal. The fire extinguishing operation mechanism receives the fire extinguishing agent release instructions and continuously provides the fire extinguishing agent to the corresponding UPS battery cabinet 1 through the supply pipeline 301 to extinguish the fire, and performs smoke recovery on the corresponding UPS battery cabinet 1 through the recovery pipeline 302 according to the smoke recovery instructions to recover the fire extinguishing agent from the smoke. After the fire extinguishing is completed, the stop fire extinguishing instruction is generated and output according to the no-fire detection signal from the fire detection mechanism 2. The fire extinguishing operation mechanism stops performing the release of the fire extinguishing agent and the recovery of the smoke according to the stop fire extinguishing instruction. The fire detection mechanism 2, the fire control controller 4, and the fire extinguishing operation mechanism are used to realize automatic control, and the action efficiency is high. The fire control controller 4 can provide the fire extinguishing agent to the UPS battery cabinet 1 where the fire occurs in the first time through the fire extinguishing operation mechanism, extinguish the fire in time, perform smoke recovery to recover the fire extinguishing agent from the smoke, avoid the expansion of the fire, and cause greater losses.

[0057] In another embodiment, the UPS fire extinguishing system further comprises a manual input module for inputting a manual fire signal and a manual no-fire signal, the fire control unit 4 can further generate and output an extinguishing agent releasing instruction and a smoke recovering instruction according to the manual fire signal, make the extinguishing operation unit release the extinguishing agent to the corresponding UPS battery cabinet 1 through the supply pipeline 301, execute smoke recovering to the corresponding UPS battery cabinet 1 according to the smoke recovering instruction through the recovering pipeline 302, and generate and output a stop extinguishing instruction according to the manual no-fire signal to make the extinguishing operation unit stop executing the extinguishing agent releasing and smoke recovering. The manual input module can be arranged at a duty room, a monitoring room or the like.

[0058] As shown in Figure 2 In another embodiment, the UPS fire extinguishing system further comprises:

[0059] an alarm device 5 electrically connected with the fire control unit 4 for generating an alarm according to an alarm instruction;

[0060] The fire control unit 4 is further configured to output the alarm instruction to the alarm device 5 according to the fire signal from the fire detection unit 2.

[0061] Specifically, the alarm device 5 is an audible and visual alarm.

[0062] More specifically, when the fire control unit 4 receives the fire signal sent by the fire detection unit 2, the fire control unit 4 generates and outputs an alarm instruction to the alarm device 5, and the alarm device 5 generates an alarm to alert the staff to take corresponding measures in time to avoid causing loss of personnel and property; in addition, the fire control unit 4 outputs a stop alarm instruction according to the no-fire detection signal from the fire detection unit 2 and sends it to the alarm device 5, and the alarm device 5 stops alarming. The alarm device 5 can be an audible and visual alarm, and the audible and visual alarm can be arranged at different locations such as a duty room, a monitoring room or the like.

[0063] As shown in Figure 1 and Figure 2 Preferably, the extinguishing operation unit comprises:

[0064] an extinguishing agent storage tank 31, a separation tower 32 and a cooling tower 33 connected in sequence through pipelines;

[0065] The cooling tower 33 is configured to reduce the temperature of the smoke in the recovering pipeline 302;

[0066] The separation tower 32 is configured to separate the extinguishing agent from the smoke cooled by the cooling tower 33;

[0067] The extinguishing agent storage tank 31 is configured to store the separated extinguishing agent;

[0068] The outlet of the extinguishing agent storage tank 31 is communicated with the inside of the cabinet of each UPS battery cabinet 1 through the supply pipeline 301.

[0069] The inlet of the cooling tower 33 is communicated with the inside of the cabinet of each UPS battery cabinet 1 through the recovery pipeline 302.

[0070] Specifically, when the UPS battery cabinet 1 catches fire, the battery module in the UPS battery cabinet 1 continuously generates oxygen, CO and olefin gas by itself, the extinguishing agent storage tank 31 continuously supplies the extinguishing agent to the UPS battery cabinet 1, the mixed smoke gas is generated in the UPS battery cabinet 1, the smoke gas in the UPS battery cabinet 1 is transported to the cooling tower 33 through the recovery pipeline 302, the cooling tower 33 can cool and dilute the mixed gas in a very short time, and then the mixed gas is transported to the separation tower 32 for separation of various gases and extinguishing agent, so as to avoid smoke gas explosion, and the recovered extinguishing agent is stored in the extinguishing agent storage tank 31 for continuous supply and recycling of the extinguishing agent. The separation tower 32 can be a gas separation device.

[0071] In another embodiment, the supply and recovery mechanism 3 further comprises a smoke gas treatment device connected with the gas separation tower, after the smoke gas is separated by the gas separation tower, the extinguishing agent, CO, olefin gas and other gases are obtained, the extinguishing agent is recycled into the extinguishing agent storage tank 31 for recycling, the CO, olefin gas and other gases are treated in the smoke gas treatment device to be harmless, and then discharged into the atmosphere to avoid air pollution. If the extinguishing agent is liquid nitrogen, the nitrogen gas is cooled and compressed to form liquid nitrogen, which is stored in the extinguishing agent storage tank 31.

[0072] As shown in Figure 1 and Figure 2 Preferably, the extinguishing operation mechanism further comprises:

[0073] A plurality of fans 34 are arranged on each UPS battery cabinet 1, and the exhaust outlet of each fan 34 is communicated and connected with the pipeline of the recovery pipeline 302.

[0074] Specifically, the fire extinguishing agent in the embodiment adopts liquid nitrogen. After the liquid nitrogen enters the UPS cabinet 1, it is vaporized to absorb a large amount of heat, so that the temperature in the UPS cabinet 1 is instantly reduced below the ignition point, and the low temperature can reduce the chemical activity of the battery and reduce or even directly stop the chemical reaction rate in the thermal runaway battery. In addition, the nitrogen gas generated by vaporization fills the entire UPS cabinet 1, which can effectively isolate the battery module and oxygen and reduce the possibility of fire and explosion in the UPS cabinet 1. At the same time, according to the smoke recovery instruction, the fan 34 can extract the mixed smoke of oxygen, CO, olefin gas and fire extinguishing agent generated in the UPS cabinet 1 due to the battery reaction, so as to reduce or even directly stop the chemical reaction rate in the thermal runaway battery, reduce the possibility of fire and explosion in the UPS cabinet 1, and effectively avoid the backflow of smoke into the UPS cabinet 1. Further, the nitrogen gas generated by vaporization of liquid nitrogen will not cause damage to the battery module, precision electronic equipment and the like, thereby ensuring the safety of other equipment in the machine room to the greatest extent while achieving fire extinguishing. The fan 34 can be an axial fan, a duct fan or the like, and is arranged at the bottom of the UPS cabinet 1, so that the smoke can only flow unidirectionally to the recovery pipeline 302.

[0075] As shown in Figure 1 and Figure 2 , preferably, the fire extinguishing agent storage tank 31 is provided with a first pressure relief valve 311, which is used to open the pressure relief when the internal pressure of the fire extinguishing agent storage tank 31 exceeds the first pressure relief valve set pressure.

[0076] Specifically, the fire extinguishing agent is liquid nitrogen, and the liquid nitrogen will vaporize to a certain extent, so that the pressure of the fire extinguishing agent storage tank 31 slowly rises. Therefore, the first pressure relief valve 311 is arranged at the top end of the fire extinguishing agent storage tank 31, which can relieve the pressure outside the fire extinguishing agent storage tank 31 when the internal pressure of the fire extinguishing agent storage tank 31 exceeds the first pressure relief valve set pressure, thereby avoiding explosion of the fire extinguishing agent storage tank 31 due to excessive pressure.

[0077] As shown in Figure 1 , preferably, each UPS battery cabinet 1 is provided with a spraying mechanism 6, and each spraying mechanism 6 is communicated with the supply pipeline 301 through a valve 101.

[0078] The fire control controller 4 is also used to output a valve opening instruction to the valve 101 according to the flame detection signal from the fire detection mechanism 2.

[0079] Specifically, in order to ensure that the fire extinguishing agent can be evenly diffused in the UPS cabinet 1 after entering the UPS cabinet 1, and achieve better fire extinguishing effect, a spraying mechanism 6 is arranged on the UPS cabinet 1, the spraying mechanism 6 is arranged to include: a connecting pipeline arranged in the UPS cabinet 1 and a plurality of nozzles arranged at intervals on the connecting pipeline, the fire extinguishing agent sprayed by the plurality of nozzles can be evenly dispersed in the UPS cabinet 1, and the valve 101 is an electric valve, which has simple structure and is easy to maintain, and can quickly act when receiving a signal.

[0080] More specifically, in order to avoid the smoke in the recovery pipeline 302 entering the UPS battery cabinet 1 where no fire occurs, causing the fire detection mechanism 2 in the UPS battery cabinet 1 to false alarm, a valve 101 can also be arranged between each UPS battery cabinet 1 and the recovery pipeline 302, the valves between the same UPS battery cabinet 1 and the supply pipeline 301 and the recovery pipeline 302 are synchronously controlled, and the fire control controller 4 outputs a valve opening instruction to the valve 101 between each UPS battery cabinet 1 and the supply pipeline 301 and the recovery pipeline 302 according to the flame detection signal from the fire detection mechanism 2. Similarly, a valve closing instruction is output according to the no-fire detection signal from the fire detection mechanism 2.

[0083] As shown in Figure 1 , preferably, the supply pipeline 301 is further provided with a second pressure relief valve 36, and the second pressure relief valve 36 is used to open the pressure relief when the internal pressure of the supply pipeline 37 exceeds the second pressure relief valve set pressure.

[0084] Specifically, since the extinguishing agent is liquid nitrogen, there is a certain vaporization during the delivery process, and the pressure of the supply pipeline 301 is increased by the booster pump 35, therefore, a second pressure relief valve 36 is arranged on the supply pipeline 301, and when the internal pressure of the supply pipeline 301 exceeds the set pressure of the second pressure relief valve, the pressure is relieved to the outside of the supply pipeline 301, so as to avoid explosion of the supply pipeline 301 due to excessive pressure; at the same time, a pressure sensor can be arranged on the supply pipeline 301, for acquiring the internal pressure of the supply pipeline 301, as a reference basis for adjusting the working frequency of the booster pump 35.

[0085] As shown in Figure 1 and Figure 2 The fire control controller 5 is electrically connected with the separation tower 32, the cooling tower 33, the booster pump 35, each fan 34, each valve 101 and each fire detection mechanism 2; the fire detection mechanism 2 detects the fire of the UPS battery cabinet 1 and outputs a flame detection signal, the fire control controller 5 outputs an extinguishing agent release instruction, a valve opening instruction and a smoke recovery instruction according to the flame detection signal from the fire detection mechanism 2, turns on the valve 101 corresponding to the valve opening instruction, starts the booster pump 35 according to the extinguishing agent release instruction, and starts the fan 34, the separation tower 32, the cooling tower 33 and the booster pump 35 corresponding to the smoke recovery instruction; the fire detection mechanism 2 outputs a no-fire detection signal, and the fire control controller 5 outputs a stop extinguishing instruction and a valve closing instruction, and closes the valve 101 corresponding to the valve opening instruction, and stops the fan 34, the separation tower 32, the cooling tower 33 and the booster pump 35 corresponding to the stop extinguishing instruction.

[0086] Preferably, the UPS fire extinguishing system further comprises a display device, which is electrically connected with the fire control controller and can display the states of the fire detection mechanism 2 and the supply recovery mechanism 3 in real time. More specifically, the display device can display the working states of the fire detection mechanism 2, the valve 101, the fan 34, the separation tower 32 and the cooling tower 33 corresponding to each UPS battery cabinet 1; in a normal state, green color is displayed; and in case of fire, red color is displayed.
