As shown in fig. 1, an embodiment of the present invention discloses a fire water tank for an energy storage module production line, which comprises a first tank body 100, a second tank body 200 and a heat exchange assembly 300. It should be noted that, during the production process of the battery module, because higher energy is stored in the lithium battery, and thermal runaway phenomena may occur during the manufacturing, transportation and storage processes due to short circuit, overcharge discharge or battery core damage, etc., thereby causing fire and explosion. Once a single module is out of control, the heat generated by the module can cause the adjacent modules to enter into a thermal control state quickly, so that a thermal control chain reaction is generated. According to the fire fighting water tank disclosed by the invention, the first tank body 100 and the second tank body 200 are arranged, the thermal runaway module 400 is put into the second tank body 200, and meanwhile, the second tank body 200 is put into the first cooling medium 101 of the first tank body 100, so that heat of the thermal runaway module 400 is dissipated, the adjacent modules are prevented from entering a thermal runaway state by the heat of the thermal runaway module 400, and the safety of equipment and operators is ensured while the thermal runaway chain reaction of the battery modules is avoided.
As shown in fig. 1, a first cooling medium 101 for dissipating heat of the thermal runaway module 400 is contained in the first box 100, and a liquid inlet 102 and a liquid outlet 103 are disposed on the first box 100, the liquid inlet 102 is communicated with the heat exchange assembly 300 through a liquid inlet pipeline 1021, and the liquid outlet 103 is communicated with the heat exchange assembly 300 through a liquid outlet pipeline 1031, so that the first cooling medium 101 circulates between the first box 100 and the heat exchange assembly 300, and heat of the thermal runaway module 400 is replaced to the external environment through the heat exchange assembly 300. Meanwhile, the thermal runaway module 400 is placed in the second box 200, and then the second box 200 is placed in the first cooling medium 101 of the first box 100, so that the thermal runaway module 400 is cooled and radiated, and the thermal runaway module 400 is placed in the second box 200, so that the damage to equipment and operators caused by explosion of the thermal runaway module 400 can be effectively prevented, and meanwhile, the phenomenon that the liquid inlet 102 and the liquid outlet 103 are blocked by particles generated by combustion of the thermal runaway module 400 can be avoided, so that a cooling circulation system is invalid.
As shown in fig. 3 and 4, in an embodiment, the first and second cases 100 and 200 are welded with steel plates to prevent the first and second cases 100 and 200 from being damaged when the thermal runaway module 400 is put in. In this embodiment, the number of the second cases 200 is at least two, and the first cases 100 have the dimensions of 300mm for length, 200mm for width and 200mm for height, so that 2-3 second cases 200 with thermal runaway modules 400 can be simultaneously put into, and meanwhile, the higher first cases 100 can enable the second cases 200 with thermal runaway modules 400 to be completely immersed, thereby accelerating cooling and improving cooling efficiency. In addition, as shown in fig. 4, the reinforcing plate 105 is disposed at the bottom of the first case 100, so that the bottom of the first case 100 is prevented from being broken due to a large impact generated by the gravity of the thermal runaway module 400 when the second case 200 having the thermal runaway module 400 is put in. The heat exchange assembly 300 adopts a dry coil, and a water pump 1022 is arranged on the liquid inlet pipeline 1021 to accelerate the flow of the first cooling medium 101 and improve the cooling efficiency. When the thermal runaway phenomenon of the single module is found, the single thermal runaway module 400 can be rapidly put into the second box 200, and meanwhile, the second box 200 is put into the first cooling medium 101 of the first box 100, and at this time, the water pump 1022 is started, so that the first cooling medium 101 circulates and flows between the first box 100 and the heat exchange assembly 300, as shown in fig. 2 (the arrow in the drawing is the heat exchange direction), and therefore, heat is dissipated for the thermal runaway module 400, so as to prevent the thermal runaway module 400 from burning and exploding, and cause damage to equipment and operators. In this embodiment, the first cooling medium 101 is an aqueous medium, and other cooling mediums such as mechanical oil, nitrate salt, polyvinyl alcohol, and aqueous trinitro solution may be used.
According to the fire-fighting water tank disclosed by the invention, the first tank body 100 is arranged, the first cooling medium 101 for radiating the thermal runaway module 400 is contained in the first tank body 100, and the first tank body 100 is provided with the liquid inlet 102 and the liquid outlet 103, wherein the liquid inlet 102 is communicated with the heat exchange component through the liquid inlet pipeline, and the liquid outlet 103 is communicated with the heat exchange component through the liquid outlet pipeline, so that the first cooling medium 101 circulates between the first tank body 100 and the heat exchange component, and the cooling efficiency is improved. Meanwhile, the second box 200 is arranged, and the thermal runaway module 400 is placed in the second box 200, so that the thermal runaway module 400 is prevented from exploding to cause injury to operators and equipment, and the dual protection function is achieved. When the thermal runaway phenomenon occurs in the single module, the single thermal runaway module 400 can be rapidly put into the second box 200, and meanwhile, the second box 200 is put into the first cooling medium 101 of the first box 100, so that heat dissipation is performed on the thermal runaway module 400, the thermal runaway module 400 is prevented from burning and exploding, and even if the thermal runaway module 400 explodes, the damage to operators and equipment can be avoided due to the protection of the second box 200.

When the second case 200, in which the thermal runaway module 400 is installed, is put into the first cooling medium 101 of the first case 100, since the thermal runaway module 400 burns to generate exhaust gas, the exhaust gas may be discharged from the exhaust port 106 to the exhaust gas collecting device through the exhaust gas collecting pipe 1061 and concentrated in transportation. It should be noted that, taking the lithium iron phosphate module as an example, the exhaust gas generated by the combustion of the thermal runaway module 400 will generate CO and C when the lithium battery is combusted 2 H 4 、H 2 S、HF、HCI、SO 2 And HCN and other harmful gases, which will cause irreversible harm to the environment and human body.
