[0037] When the battery pack in a new energy vehicle fails safely after thermal runaway occurs, a large amount of smoke will be released, which contains a large amount of smoke, a large amount of particulate matter, and a large amount of toxic gas, which seriously endangers the health of passengers and reduces the quality of new energy vehicles. At present, many feasible solutions have been proposed for the high temperature and high pressure problems caused by thermal runaway, but no effective solution has been proposed for the particulate matter and harmful gases generated by thermal runaway.
[0038] Reference below Figure 1-Figure 8 A thermal runaway processing device for a battery according to an embodiment of the utility model is described.
[0039] According to the utility model, the thermal runaway processing device 1 for the battery 20 includes a first adsorption device 11 and a second adsorption device 12. The first adsorption device 11 is provided with a filter inlet suitable for communicating with the battery 20, and the first adsorption device 11 is suitable for filtering large particles in the gas exhausted by the battery 20; the second adsorption device 12 is communicated with the first adsorption device 11 and is arranged downstream of the first adsorption device 11, and a accommodating cavity and an exhaust hole connecting the accommodating cavity with the outside are formed in the second adsorption device 12, and a filter medium for reacting with the residual gas is provided in the accommodating cavity, and the reacted gas is discharged through the exhaust hole.
[0040] like Figure 1 and Figure 2 As shown, according to the thermal runaway treatment device 1 of the utility model, a first adsorption device 11 and a second adsorption device 12 are respectively arranged on the outside of the battery 20 pack, and the gas generated by the thermal failure of the battery 20 passes through the first adsorption device 11 and the second adsorption device 12 in sequence, wherein the first adsorption device 11 is suitable for filtering large particles in the gas, and the large volume of substances in the gas are controlled in the first adsorption device 11, and the gas filtered by the first adsorption device 11 enters the second adsorption device 12, and a filter medium that reacts with the remaining gas is arranged in the second adsorption device 12, and the filter medium can adsorb and dissolve the small particles in the remaining gas, so that the remaining small particles in the gas are retained in the filter medium, without The method is to be discharged to the outside along with the gas. In addition, the filter medium can react with harmful gases in the gas to generate harmless gas. Among them, the gas generated by thermal runaway of the battery 20 first passes through the first adsorption device 11 to filter large particles to ensure that large particles in the gas will not enter the second adsorption device 12. The filter medium in the second adsorption device 12 will not be affected by the large particles, ensuring that the filter medium can fully react with the remaining gas. The reacted gas flows out to the outside and is harmless to the human body, thereby ensuring the safety of the passengers. At the same time, the liquid filter medium 122 can take away the heat in the gas, cool the gas, reduce the damage of high-temperature exhaust to inflammable materials such as wiring harnesses and decorations in the vehicle, and improve the safety of the vehicle.
[0041] According to the thermal runaway processing device 1 for a battery 20 of the utility model, a first adsorption device 11 and a second adsorption device 12 are arranged outside the battery 20 to process the gas generated by the thermal runaway of the battery 20. The gas passes through the first adsorption device 11 and the second adsorption device 12 in sequence. The first adsorption device filters large particles in the gas. The second adsorption device 12 reacts with the gas through a filter medium to adsorb and filter small particles in the gas, and reacts with harmful components in the gas to generate harmless gas. The gas is first filtered by the first adsorption device 11, and large particles in the gas are retained in the first adsorption device 11 to prevent large particles from entering the second adsorption device 11 with the gas, thereby ensuring that the filter medium in the second adsorption device 11 fully reacts with the gas and improves the filtering effect. At the same time, the gas passes through the first adsorption device 11 and the second adsorption device 12 in sequence for adsorption and filtration, which can achieve cooling of the gas and reduce the damage of high-temperature gas to items such as wiring harnesses and decorations in the vehicle.
[0042] According to one embodiment of the utility model, the filter medium is constructed as a liquid filter medium 122, and a connecting pipe 121 is provided between the air outlet of the first adsorption device 11 and the air inlet of the second adsorption device 12 for conveying residual gas, and the outlet of the connecting pipe 121 is located below the liquid level of the liquid filter medium 122.
[0043] Specifically, the gas filtered by the first adsorption device 11 flows into the second adsorption device 12 through the connecting pipe 121, wherein the outlet of the connecting pipe 121 extends into the liquid filter medium 122 and is located below the liquid level of the liquid filter medium 122, ensuring that the gas flows into the liquid filter medium 122 for filtration, and the gas does not flow out directly, thereby ensuring the filtering effect of the gas. The gas passes into the liquid filter medium 122, and the gas is in full contact with the liquid filter medium 122, and small particles in the gas are dissolved and adsorbed by the liquid filter medium 122.
[0044] According to one embodiment of the utility model, the thermal runaway processing device 1 also includes a diffuser, which is arranged in the accommodating chamber and located below the liquid level of the liquid filter medium 122. The outlet of the connecting pipe 121 is located below the diffuser, and the diffuser is suitable for dividing the remaining gas discharged through the outlet of the connecting pipe 121 into bubbles.
[0045] Specifically, a diffuser is further provided at the bottom of the accommodating chamber. The diffuser is located below the liquid surface of the liquid filter medium 122 to ensure that the diffuser is completely immersed in the liquid filter medium 122. The outlet of the connecting pipeline 121 is located below the diffuser. The gas enters the liquid filter medium 122 and forms a plurality of large bubbles 123. Due to pressure reasons, the large bubbles 123 will continue to pass through the diffuser and be divided by the diffuser to form a plurality of small bubbles 124. The small bubbles 124 are in full contact with the liquid filter medium 122, and the small particles in the gas are fully absorbed. The harmful gas reacts with the chemical reagent in the liquid filter medium 122 to generate harmless gas. By providing a diffuser in the accommodating chamber, the gas can be divided into smaller bubbles, and the bubbles are in more full contact with the liquid filter medium 122, which is beneficial to improving the filtering effect of the gas and improving safety.
[0046] According to an embodiment of the present invention, the diffuser is configured as a diffuser plate 13, the outer edge of the diffuser plate 13 is sealed to the inner wall of the accommodating chamber, and a plurality of densely arranged through holes 131 are formed on the diffuser plate 13 for dividing the remaining gas.
[0047] like Figure 7 As shown, a plurality of through holes 131 are formed on the diffuser plate 13, and the plurality of through holes 131 are densely arranged, thereby improving the airflow segmentation effect of the diffuser plate 13, making the contact between the gas and the liquid filter medium 122 more complete, thereby improving the gas filtering effect, and the outer edge of the diffuser plate 13 is sealed with the inner wall of the accommodating cavity, thereby ensuring that the gas will only pass through the through holes 131, thereby improving the filtering effect.
[0048] According to one embodiment of the utility model, the diameter of the through hole 131 is smaller than the diameter of the connecting pipe 121, the gas flows out from the connecting pipe 121 and generates large bubbles, the large bubbles 123 are divided by the through hole 131 to form small bubbles, the small bubbles 124 can be more fully dissolved in the liquid filter medium 122, and the small particles in the gas can be more fully dissolved in the liquid filter medium 122.
[0049] According to one embodiment of the utility model, the thermal failure treatment device also includes a reflux device 14 and a reflux pipe 141. The reflux device 14 is arranged in the second adsorption device 12. A collecting chamber for collecting the liquid filter medium 122 is formed inside the reflux device 14. The collecting chamber is connected to the accommodating chamber and the exhaust hole respectively; the reflux pipe 141 connects the collecting chamber with the accommodating chamber, and the outlet height of the reflux pipe 141 is higher than the liquid level height of the liquid filter medium 122.
[0050] like Figure 6As shown, a reflux device 14 is also provided in the second adsorption device 12. After the gas is filtered by the liquid filter medium 122 in the accommodating chamber, it is discharged to the outside through the reflux device 14. A collecting chamber for collecting the liquid filter medium 122 is formed inside the reflux device 14. During the operation of the vehicle, due to the shaking of the vehicle body, the liquid filter medium 122 in the accommodating chamber will flow into the collecting chamber, causing the loss of the liquid filter medium 122 in the accommodating chamber. The reduction of the liquid filter medium 122 in the accommodating chamber will reduce the filtering effect on the gas. Therefore, a reflux pipe 141 is provided at the bottom of the reflux device 14. The reflux pipe 141 connects the collecting chamber with the accommodating chamber. Since the height of the reflux device 14 is higher than the height of the accommodating chamber, due to gravity, the liquid filter medium 122 collected in the collecting chamber flows into the accommodating chamber through the reflux pipe 141, ensuring that sufficient liquid filter medium 122 is retained in the accommodating chamber, ensuring the adsorption effect of the liquid filter medium 122 on particulate matter and harmful gases in the gas.
[0051] According to one embodiment of the utility model, the thermal runaway treatment device 1 also includes a filter unit 15, which is arranged in the first adsorption device 11. The filter unit 15 is arranged between the air intake inlet and the exhaust outlet of the first adsorption device 11 and is suitable for filtering particulate matter contained in the gas passing through the first adsorption device 11.
[0052] Specifically, the gas generated by the battery 20 enters the first adsorption device 11 through the air inlet, and the gas is discharged from the exhaust outlet after being filtered by the filter unit 15, wherein a plurality of filter holes may be provided on the filter unit 15, and the diameter of the filter holes is smaller than the maximum diameter of large particles in the gas without affecting the filtering effect of the filter unit 15, so as to retain the large particles in the gas in the filter unit 15, thereby filtering the gas, and the gas entering the second adsorption device 12 contains only small particles, so as to facilitate the liquid filter medium 122 in the second adsorption device 12 to adsorb the gas.
[0053] According to one embodiment of the utility model, the filter part 15 is constructed into multiple parts and is arranged in sequence between the air inlet and the exhaust outlet of the first adsorption device 11; each filter part 15 includes a filter element 151 and a filter plate 152, the filter plate 152 is constructed into two parts and is arranged at intervals on both sides of the thickness direction of the filter element 151, and a plurality of filter holes 1521 penetrating in the thickness direction are formed on the surface of each filter plate 152; wherein the filter plate 152 and the filter element 151 extend in a zigzag shape respectively.
[0054] like Figure 3 and Figure 4As shown, a plurality of filter sections 15 are arranged in the first adsorption device 11, and each filter section 15 is respectively composed of a filter element 151 and a filter plate 152. Filter holes are formed on the filter element 151, and the filter element 151 will filter out particles with diameters larger than its filter holes. Filter plates 152 are respectively arranged on both sides of the filter element 151 in the thickness direction, and the filter plates 152 support and fix the filter element 151. Filter holes 1521 are arranged on the filter plate 152, and the aperture of the filter holes 1521 on the filter plate 152 is larger than the maximum diameter of the particulate matter. Without affecting the filtering effect of the filter element 151, the filter plate 152 and the filter element 151 extend in a broken line shape, which can reduce the air flow resistance while increasing the contact area between the filter section 15 and the gas, thereby improving the filtering effect.
[0055] According to an embodiment of the present invention, the outer edge of each filter portion 15 is sealed and connected to the inner wall of the first adsorption device 11 .
[0056] Specifically, the outer edge of the filter part 15 is sealed with the inner wall of the first adsorption device 11. In the direction of gas flow, the airflow passes through the filter part 15, and large particles in the gas are filtered by the filter part 15 and remain on the surface of the filter part 15, thereby ensuring the sealing of the outer edge of the filter part 15. The outer edge of the filter part 15 has good sealing performance, and the gas will not flow out from the edge of the filter part 15, which is also beneficial to improving the filtering effect of the filter part 15 on the gas.
