Description
本新型是關於一種電池滅火系統，特別是關於一種應用於電池的淹浸式電池滅火系統。 The present invention relates to a battery fire extinguishing system, and more particularly to a flooded battery fire extinguishing system applied to a battery.
電動車、儲能設備等，都是以電池為儲能及動力的來源。由於電動車的動力來源為電池，因此，無論是哪一種電動車，如BEV(純電動車)、HEV(混合動力車)、PHEV(插電式混合動力車)與REEV(增程式電動車)、燃料電池車、太陽能電池車等，都需要能夠提供大電流的電池來進行動力的轉換。目前，大電流的電池以高能量密度電池為主流，例如，鋰離子電池，其具有能量密度高的特性，同時，其也是以有機溶液為電解液的電池。 Electric vehicles, energy storage equipment, etc., all use batteries as a source of energy storage and power. Since the power source of the electric vehicle is the battery, no matter which kind of electric vehicle, such as BEV (pure electric vehicle), HEV (hybrid vehicle), PHEV (plug-in hybrid vehicle) and REEV (extended electric vehicle) , fuel cell vehicles, solar battery vehicles, etc., all need to be able to provide a large current battery for power conversion. At present, high-current batteries are dominated by high-energy-density batteries, for example, lithium-ion batteries, which have high energy density characteristics, and are also batteries in which an organic solution is used as an electrolyte.
然而，層出不窮的鋰離子電池的***、碰撞後燃燒等事件，也讓鋰離子類的高能量密度電池的安全性蒙上一層陰影。而鋰離子電池失火的特性在於，即便外部的火焰已經熄滅，但內部電池的化學反應仍在持續，因此，常常發生二次燃燒的狀況。目前為止，仍無具體有效的滅火系統可支應鋰離子電池類的高能量密度電池的滅火，甚至，能夠防止其二次燃燒的狀況。 However, the explosion of lithium-ion batteries and the post-collision combustion events have cast a shadow on the safety of lithium-ion high-energy-density batteries. The characteristic of the lithium-ion battery misfire is that even if the external flame has been extinguished, the chemical reaction of the internal battery continues, and therefore, secondary combustion often occurs. So far, there is no specific effective fire extinguishing system that can support the fire extinguishing of high energy density batteries of lithium ion batteries, and even prevent secondary combustion.
因此，如何開發一種新的電池滅火系統，讓其可在電池因故而發生燃燒(無論是因為碰撞、內部短路、熱失控等)的狀況下，可以在燃燒初期立即撲滅火勢，甚至，進一步防止其發生二次燃燒，成為電池滅火系統開發的重要發展方向。 Therefore, how to develop a new battery fire extinguishing system that allows the battery to burn immediately after the combustion (whether due to collision, internal short circuit, thermal runaway, etc.), or even further prevent it The occurrence of secondary combustion has become an important development direction for the development of battery fire extinguishing systems.
有鑑於此，本新型提出一種淹浸式電池滅火系統，運用一封閉的電池空間，並提供以水溶液為主體的滅火系統，在偵測到電池發生燃燒的狀況下，將水溶液注滿此電池空間後進行電池的滅火。如此，可達到災害發生的第一時間點就將災害鎖定於該電池空間內，進而降低災害損失，並預防電池二次燃燒的特殊技術功效。 In view of this, the present invention proposes a flooded battery fire extinguishing system that uses a closed battery space and provides an aqueous solution-based fire extinguishing system that fills the battery space with an aqueous solution under the condition that the battery is detected to be burning. After the battery is extinguished. In this way, the disaster can be locked into the battery space at the first time point of the disaster, thereby reducing the disaster loss and preventing the special technical effect of secondary combustion of the battery.
本新型提供一種淹浸式電池滅火系統，包含：至少一水溶液容置空間，用以容置一水溶液；至少一電池箱，每個該電池箱具有一電池空間，用以容置至少一電池；一配水管路，連接該水溶液容置空間與該至少一電池箱，並於每個該電池箱體內配置至少一個出水口；及至少一個出水控制閘，於該出水口配置一個該出水控制閘，於該電池發生燃燒時出水，以使該水溶液淹浸該電池箱內的該電池而進行滅火。 The present invention provides a flooding type battery fire extinguishing system, comprising: at least one aqueous solution accommodating space for accommodating an aqueous solution; at least one battery case, each of the battery cases having a battery space for accommodating at least one battery; a water distribution pipe connecting the aqueous solution accommodating space and the at least one battery box, and arranging at least one water outlet in each of the battery case bodies; and at least one water outlet control gate, wherein the water outlet control gate is disposed at the water outlet The water is discharged when the battery is burned, so that the aqueous solution is flooded by the battery in the battery case to extinguish the fire.

本新型係運用淹浸式的方式，讓電池(例如鋰離子電池等高能量密度的有機類電池)於發生燃燒時(火災)，透過將水溶液將其淹浸，而達到主動滅火的目的。更進一步地，由於電池所擺置的電池箱中已經充入了水溶液而將電池淹浸，因此，立即達到電池箱中的電池降溫而滅火與降低電池內部化學反應速率，並且，由於電池已經經由水溶液與外界隔離，而使電池不會接觸空氣，進而阻斷了氧氣的供應，進一步阻斷了電池的進一步燃燒的可能。此外，藉由水溶液中的其他電解液而使得電池能進行放電釋放電池能量與降溫，更進一步地防止了電池的二次自燃的可能性。因此，藉由本新型的淹浸式電池滅火系統，可達到降低或災損失到發生事件的該電池箱，而不 會進一步擴散到其他的電池箱。 The present invention uses a flooding method to allow a battery (such as a lithium-ion battery or the like, a high-energy-density organic battery) to be actively fire-extinguished by inhaling an aqueous solution when it is burned (fire). Further, since the battery box in which the battery is placed has been filled with the aqueous solution to flood the battery, the battery in the battery box is immediately cooled to extinguish the fire and the internal chemical reaction rate is lowered, and since the battery has passed through The aqueous solution is isolated from the outside world, so that the battery does not contact the air, thereby blocking the supply of oxygen, further blocking the possibility of further combustion of the battery. In addition, the battery can be discharged by the other electrolyte in the aqueous solution to release the energy and temperature of the battery, and the possibility of secondary spontaneous combustion of the battery is further prevented. Therefore, with the flooded battery fire extinguishing system of the present invention, it is possible to achieve the reduction or damage to the battery box in which the event occurs, without Will spread further to other battery boxes.
請參考第1圖，其為本新型之淹浸式電池滅火方法流程圖，包含： 步驟S101：提供一電池所需之一電池箱與一水溶液容置空間，該水溶液容置空間注入一水溶液。其中該水溶液係選自自來水、氯化鈉(NaCl)溶液、氫氧化鈉(NaOH)溶液、硫酸鈉(NaSO4)溶液，各溶液之電解質重量百分比濃度介於0.2%~26%；或者，各溶液之電解質重量百分比濃度介於0.2%~20%介於0.2%~5%；或者，各溶液之電解質重量百分比濃度介於10%~20%。 Please refer to FIG. 1 , which is a flow chart of the method for extinguishing a flooded battery of the present invention, comprising: Step S101: Providing a battery box required for a battery and an aqueous solution accommodating space, the aqueous solution accommodating space injecting an aqueous solution. Wherein the aqueous solution is selected from the group consisting of tap water, sodium chloride (NaCl) solution, sodium hydroxide (NaOH) solution, sodium sulfate (NaSO4) solution, and the electrolyte concentration percentage of each solution is between 0.2% and 26%; or, each solution The electrolyte concentration percentage ranges from 0.2% to 20% between 0.2% and 5%; or, the electrolyte concentration percentage of each solution is between 10% and 20%.
採用如氯化鈉(NaCl)溶液、氫氧化鈉(NaOH)溶液、硫酸鈉(NaSO4)溶液等不同電解質溶液，可有效地快速對電池當中的鋰離子電池進行放電釋放能量。 The use of different electrolyte solutions such as sodium chloride (NaCl) solution, sodium hydroxide (NaOH) solution, sodium sulfate (NaSO4) solution, etc., can effectively discharge the lithium ion battery in the battery to release energy.
步驟S102：偵測該電池燃燒狀態。其中偵測該電池燃燒狀態之步驟，係以一密閉型灑水頭的感熱模式感知後，連動該水溶液容置空間當中的該水溶液進行注滿該電池箱。其中，密閉型灑水頭之感熱自動灑水溫度介於攝氏60度至攝氏150度之間。 Step S102: detecting the burning state of the battery. The step of detecting the burning state of the battery is sensed by a heat sensitive mode of a sealed sprinkler head, and the aqueous solution in the aqueous solution holding space is linked to fill the battery case. Among them, the heat-sensitive automatic sprinkling temperature of the sealed sprinkler head is between 60 degrees Celsius and 150 degrees Celsius.
或者，偵測該電池燃燒狀態之步驟，係以一火災感知器感知，再由一控制主機切換一開放式灑水頭以控制一電磁閥而連動該水溶液容置空間當中的該水溶液進行注滿該電池箱。 Alternatively, the step of detecting the burning state of the battery is sensed by a fire sensor, and then an open sprinkler is switched by a control host to control a solenoid valve to interlock the aqueous solution in the aqueous solution housing space to fill the battery box.
步驟S103：當該電池箱中的該電池發生燃燒狀態時，將該水溶液容置空間中之該水溶液淹浸該電池箱內的該電池而進行滅火。 Step S103: when the battery in the battery box is in a burning state, the aqueous solution in the aqueous solution accommodating space is flooded with the battery in the battery box to extinguish the fire.
如前所述，當含有電解質的水溶液淹浸電池箱內的電池後，可即刻降低電池的溫度與降低電池內部化學反應速率，而直接進行滅火。其二，由於電池被淹浸在水溶液中，而與外界空氣隔絕，進而隔絕了氧氣，而降低了進一步燃燒的可能。其三，水溶液中的電解質可將電池進行放電與釋放能量，進一步降低電池燃燒的可能。 As described above, when the aqueous solution containing the electrolyte floods the battery in the battery case, the temperature of the battery can be immediately lowered and the chemical reaction rate inside the battery can be lowered, and the fire can be directly performed. Second, since the battery is flooded in the aqueous solution, it is isolated from the outside air, thereby isolating the oxygen, thereby reducing the possibility of further combustion. Third, the electrolyte in the aqueous solution can discharge the battery and release energy, further reducing the possibility of burning the battery.
此外，更可包含另一步驟：對該水溶液容置空間當中的該水溶液進行加壓，以使該水溶液可加速注滿對應的該電池箱。加壓的方式可透過重物加壓法，也就是，將水溶液容置空間上方擺置重物，運用重物下壓。或者，採用高度加壓法，也就是，將水溶液容置空間擺置於高處。或者，外加一馬達進行加壓等。此外，其他的加壓技術有非常多種，於此不詳細列舉。 In addition, a further step may be included: pressurizing the aqueous solution in the aqueous solution accommodation space so that the aqueous solution can accelerate the filling of the corresponding battery case. The pressurized method can be carried out by a heavy object pressing method, that is, a heavy object is placed above the aqueous solution holding space, and the weight is pressed down. Alternatively, a high pressure method is employed, that is, the aqueous solution accommodation space is placed at a high position. Alternatively, a motor is added for pressurization or the like. In addition, there are many other pressurization techniques, which are not enumerated in detail herein.
如前所述者，對電池箱中的電池進行淹浸的技術：首先，要提供一個供水溶液的系統，也就是，儲水裝置(也就是水溶液容置空間)以及對應的配水管路；其次，要提供偵測電池燃燒的機制，如前所述，可採用密封型灑水器或者火災感知器；其三，要於發生電池燃燒的狀況，即刻提供水溶液，讓燃燒的電池淹浸到水溶液中；水溶液若能採用鈉系電解液，將可加速電池的放電速度。以下，將列舉數個具體實施例，來說明本新型的淹浸式電池滅火系統。 As mentioned above, the technique of flooding the battery in the battery box: first, to provide a system for supplying an aqueous solution, that is, a water storage device (that is, an aqueous solution accommodation space) and a corresponding water distribution pipe; To provide a mechanism for detecting the burning of the battery, as described above, a sealed sprinkler or a fire sensor can be used; thirdly, in the case of battery burning, an aqueous solution is provided immediately, and the burning battery is flooded into the aqueous solution. If the aqueous solution can use a sodium-based electrolyte, the discharge rate of the battery can be accelerated. Hereinafter, a plurality of specific embodiments will be cited to illustrate the flooded battery fire extinguishing system of the present invention.

In this embodiment, each of the battery boxes 301, 302 is configured with three water outlets and three water outlet control gates (501-503, 504-506).
在此實施例中，係運用了密閉型灑水頭來作為出水控制閘50l-506。密閉型灑水頭之感熱自動灑水溫度介於攝氏60度至攝氏150度之間，換言之，只要到了設定的自動灑水溫度，密閉型灑水頭就會爆開後進行自動灑水，進而使水箱10當中的水溶液注入電池箱301或電池箱302當中，使電池箱301或電池箱303當中的電池91、93等被水溶液淹浸，進而達到前述的滅火效果。 In this embodiment, a sealed sprinkler head is used as the water outlet control gates 50l-506. The temperature of the closed sprinkler head is between 60 degrees Celsius and 150 degrees Celsius. In other words, as soon as the set automatic sprinkling temperature is reached, the sealed sprinkler head will burst and then automatically sprinkle water, thus making the water tank The aqueous solution of 10 is injected into the battery case 301 or the battery case 302, so that the batteries 91, 93 and the like among the battery case 301 or the battery case 303 are flooded with the aqueous solution, thereby achieving the aforementioned fire extinguishing effect.

Unlike the embodiment of the 2A-2C diagram, in the embodiment of the 3A-3C diagram, the water outlet control gates 501-506 are respectively disposed at the bottoms of the battery boxes 301, 302. And also use the airtight The sprinkler head is used as the water outlet control gate 501-506. The rest are the same as those in Figure 2A-2C and will not be described again.
由第2A-2C圖的實施例以及第3A-3C圖的實施例可知，出水控制閘501-506可以設置於電池箱301、302的頂部或者是底部或者側邊(未繪出)。相對應地，配水管路81、82也對應配置於電池箱301、302的頂部或者是底部或者側邊。換言之，由於本新型的目標是將整個電池箱以水溶液淹浸，因此，從哪裡出水均可。 As can be seen from the embodiment of Figs. 2A-2C and the embodiment of Figs. 3A-3C, the effluent control gates 501-506 can be disposed on the top or bottom or side of the battery compartments 301, 302 (not shown). Correspondingly, the water distribution lines 81, 82 are also disposed on the top or bottom or side of the battery boxes 301, 302. In other words, since the object of the present invention is to flood the entire battery case with an aqueous solution, it is possible to effluent from there.
密閉型灑水頭之感熱自動灑水，可以不需運用到控制主機20，控制主機20在第2A-2C圖的實施例以及第3A-3C圖的實施例中，係運用在控制加壓裝置40的加壓用途，例如抽水馬達，其受控於控制主機20，其在密閉型灑水頭爆裂後自動加壓以進行灑水。如前所述，加壓的方式可以另外採用高度加壓法，也就是，將水溶液容置空間擺置於高處，運用重力，此即為第2A-2C圖與第3A-3C圖的實施例所繪示，當水箱10配置於高於電池箱301、302時，即可讓水箱10當中的水溶液產生較高的位能，進而對配水管路81、82以位能來實現加壓的功能。另一種加壓方式，也可採用在水溶液容置空間上方擺置一重物來做為加壓裝置40。 The heat-sensitive automatic sprinkling of the sealed sprinkler head can be applied to the control unit 20 without using the control unit 20, and the control unit 20 is used in the embodiment of the 2A-2C diagram and the embodiment of the 3A-3C diagram. The pressurized use, such as a pumping motor, is controlled by the control unit 20, which automatically pressurizes after the sealed sprinkler head bursts to sprinkle water. As mentioned above, the pressurization method can additionally adopt a high pressurization method, that is, the aqueous solution accommodation space is placed at a high place, and gravity is used, which is the implementation of the 2A-2C map and the 3A-3C map. For example, when the water tank 10 is disposed above the battery boxes 301 and 302, the aqueous solution in the water tank 10 can generate a higher potential energy, and the water distribution lines 81 and 82 can be pressurized by the potential energy. Features. In another type of pressurization, a weight may be placed above the aqueous solution accommodation space as the pressurizing means 40.
