In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model, but the present utility model may be practiced in other ways other than those described herein, and persons skilled in the art will readily appreciate that the present utility model is not limited to the specific embodiments disclosed below.

Furthermore, the terms "first" to "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In order to improve the safety of the battery during use or storage, the thermal runaway smoke generated by thermal runaway of the battery needs to be subjected to centralized treatment, so that the treated thermal runaway smoke can not generate potential safety hazards, and the potential hazards of pollution and damage of the thermal runaway smoke to the environment are avoided.
At present, when thermal runaway flue gas is treated, generally, a explosion venting channel of a battery or a battery pack is connected with a thermal runaway flue gas treatment device through a flue gas pipeline, and the thermal runaway flue gas treatment device is used for treating the thermal runaway flue gas generated by the thermal runaway of the battery, so that the risks of safety accidents such as explosion are reduced. The thermal runaway flue gas treatment device can be specifically a cooling device for cooling the thermal runaway flue gas, or an adsorption device for carrying out adsorption treatment on gas in the thermal runaway flue gas, or an ignition device for directly igniting the thermal runaway flue gas, or a combination of two or three modes.
However, when the battery is in thermal runaway, the generated thermal runaway flue gas has a large amount of combustible gas and part of impurities, namely solid sticky matters, solid particles, caking matters and the like except gas and vaporized electrolyte in the thermal runaway flue gas, and if the impurities are not treated, the flue gas pipeline and devices in the thermal runaway flue gas treatment device are likely to be blocked.
At present, two types of impurity removal modes exist in the thermal runaway flue gas: filtering and adsorbing. When the impurity is removed by adopting a filtering mode, for example, when the impurity is filtered by adopting a filter screen and the like, if holes in the filter screen are dense, the impurity in the thermal runaway flue gas is easy to be attached to the surface of the filter screen, and the impurity can block the filter screen to influence the passing of the thermal runaway flue gas; if the holes in the filter screen are loose, impurities can directly pass through the filter screen and enter the subsequent pipeline, and the filtration cannot be realized. Therefore, when impurities are removed by filtration, the filter screen is more likely to be clogged as the filtration accuracy increases, and the filtration effect is more likely to be lost as the filtration accuracy decreases. When adopting ordinary adsorption equipment to get rid of impurity, because adsorption material closely sets up in the adsorption shell, increased the resistance that thermal runaway flue gas flows, make the unable quick discharge of thermal runaway flue gas, probably produced the potential safety hazard.
Based on the problems, the utility model provides a battery thermal runaway flue gas pretreatment device. The battery thermal runaway flue gas pretreatment device not only can fully adsorb impurities in the thermal runaway flue gas so that the thermal runaway flue gas passing through the pretreatment device can not block a flue gas pipeline and the thermal runaway flue gas treatment device, but also has smaller resistance when the thermal runaway flue gas passes through the pretreatment device, and the thermal runaway flue gas can quickly pass through the pretreatment device so that the thermal runaway flue gas can be quickly discharged to the rear thermal runaway flue gas treatment device.
As shown in fig. 1 to 6, the battery thermal runaway flue gas pretreatment device provided in the present embodiment specifically includes an adsorption casing 1 and a plurality of adsorption plates 2 mounted on the adsorption casing 1. The flue gas channel 11 that this absorption casing 1 interior has thermal runaway flue gas to pass through, a plurality of absorption boards 2 are installed in proper order on absorption casing 1 along the direction that thermal runaway flue gas flows, and adjacent absorption board 2 stagger arrangement in flue gas channel 11 for the flow of thermal runaway flue gas is the wave in the flue gas channel. At the same time, the adsorption surface 21 of each adsorption plate 2 is provided with an adsorption material 22, and the adsorption material 22 is used for adsorbing impurities in the thermal runaway flue gas. The adsorption surface 21 of the adsorption plate 2 refers to the end surface or side surface of the adsorption plate 2 that is in contact with the thermal runaway flue gas. In this embodiment, the adsorption surface is preferably a surface of the adsorption plate 2 facing the inflow direction of the thermal runaway flue gas, and the adsorption surface 21 is preferably perpendicular to the flow direction of the thermal runaway flue gas, and an adsorption material is disposed on the adsorption surface, so that the adsorption material can sufficiently contact with the thermal runaway flue gas, and further can sufficiently adsorb impurities in the thermal runaway flue gas, so that the discharged thermal runaway flue gas is as free of solid substances as possible.
If a plurality of adsorption plates 2 are not staggered in the flue gas channel 11 of the adsorption shell 1, only the adsorption plates 2 are installed on the same side, and because the thermal runaway flue gas has a certain pressure, when the thermal runaway flue gas passes through, the thermal runaway flue gas can directly pass through the side of the flue gas channel 11, on which the adsorption plates 2 are not installed, and at the moment, the effect of adsorbing impurities by the adsorption plates 2 is difficult to achieve. Therefore, the plurality of adsorption plates 2 in this embodiment are staggered in the flue gas channel 11 of the adsorption housing 1, so that the flow of the thermal runaway flue gas is in a wave shape, the thermal runaway flue gas is arranged in the battery, and when the thermal runaway flue gas enters the adsorption housing 1 and passes through the multi-layer adsorption plates 2, the thermal runaway flue gas can be ensured to be fully adsorbed with impurities by the adsorption plates 2, and meanwhile, the thermal runaway flue gas can be ensured to smoothly pass through without generating larger resistance. In addition, the plurality of adsorption plates 2 are arranged in the flue gas channel 11 of the adsorption shell 1 in a staggered manner, so that the travel of the thermal runaway flue gas in the adsorption shell 1 can be increased, the thermal runaway flue gas can be cooled as much as possible in the adsorption shell, and impurities in the thermal runaway flue gas can be fully adsorbed.
As shown in fig. 2 and 3, the adsorption housing 1 has a flue gas channel 11 through which the thermal runaway flue gas flows, the flue gas channel 11 may be a straight-through channel or a curved channel, and the cross section of the flue gas channel 11 may be circular, square, etc., so long as the thermal runaway flue gas can smoothly pass through and the adsorption plate 2 is convenient to install.
In this embodiment, considering the overall aesthetic property and installability, the adsorption housing 1 is preferably made of a circular straight pipe, and the pipe diameter of the circular pipe can be consistent with the pipe diameter of the flue gas pipeline and the pipeline in the thermal runaway flue gas treatment device. Meanwhile, for convenient installation, the inlet and the outlet of the adsorption shell 1 are also provided with a connecting plate 15, the connecting plate 15 is provided with a mounting hole, the connecting plate 15 is convenient for the pretreatment device to be connected with a flue gas pipeline or a pipeline in a thermal runaway flue gas treatment device, further, the end surface of the connecting plate 15 is provided with an annular groove 16 for placing a sealing ring, and the sealing ring can be installed in the annular groove 16 so as to ensure the tightness when the adsorption shell 1 is connected with an external pipeline. In other embodiments, the inlet and outlet of the adsorption housing 1 may also be provided with connection flanges, through which it is connected to a flue gas line or a thermal runaway flue gas treatment device.
During actual installation, the adsorption plate 2 and the adsorption shell 1 can be assembled in a fixed connection manner, and the adsorption plate 2 can be detachably installed on the adsorption shell 1, specifically, the following installation manner can be adopted.
Firstly, fixedly connecting the adsorption plate 2 with the inner surface of the side wall of the adsorption shell 1, for example, fixing the adsorption plate 2 with the inner surface of the side wall of the adsorption shell 1 by adopting a welding mode and the like;
Secondly, processing a plurality of blind grooves 13 on the inner surface of the side wall of the adsorption shell 1, wherein one end of the adsorption plate 2 is embedded into the blind grooves 13;
When the structure is installed, firstly, the adsorption plate 2 is placed in the flue gas channel 11 from the inlet or the outlet of the adsorption shell 1, and then, one end of the adsorption plate 2 is tightly embedded into the blind groove 13; this detachable mounting method can replace the new adsorption plate 2 or the adsorption material 22 when the adsorption material 22 on the adsorption plate 2 loses the adsorption effect, but has the following disadvantages: during installation, the adsorption plates 2 are required to be placed into the flue gas channels 11 one by one from the inlet or the outlet of the adsorption shell 1 for assembly, the installation process is complicated, and meanwhile, when the adsorption material 22 on the adsorption plates 2 fails and needs to be replaced, the whole battery thermal runaway flue gas pretreatment device is required to be detached from the pipeline system, so that the adsorption plates 2 or the adsorption material 22 can be replaced, the replacement is inconvenient, and the replacement efficiency is low;
Thirdly, a plurality of inserting through grooves 12 communicated with the flue gas channel 11 are processed on the side wall of the adsorption shell 1, and the adsorption plate 2 is arranged on the adsorption shell 1 through the inserting through grooves 12;
When the structure is installed, the adsorption plate 2 can be directly inserted into the flue gas channel 11 of the adsorption shell 1 from the outside of the adsorption shell 1 through the plugging through groove 12, and then the adsorption plate 2 and the adsorption shell 1 are fixed.
Among the above three structures, the third structure is the optimal mode, and this kind of structure not only can realize the quick installation of adsorption plate 2 or adsorption material 22, and foremost can realize the change of adsorption plate 2 or adsorption material 22 when not dismantling whole battery thermal runaway flue gas preprocessing device, and change efficiency is higher.
The structure of the adsorption plate 2 will be described below taking a third external plug-in type of installation as an example.
The side of the adsorption plate 2 in this embodiment is vertically connected with the mounting plate 4, the adsorption plate 2 and the mounting plate 4 are vertically installed to form a T-shaped structure, and when in specific assembly, the adsorption plate 2 and the side of the mounting plate 4 can be directly fixedly connected, and through grooves can be processed on the mounting plate 4, and the adsorption plate 2 is connected with the mounting plate 4 by embedding the through grooves. The mounting plate 4 not only can limit the adsorption plate 2 so that the adsorption plate 2 can be accurately mounted in the insertion groove 12, but also can facilitate reliable assembly of the adsorption plate 2 and the adsorption shell 1. When this mounting panel 4 is connected with absorption casing 1, can set up installation boss 14 around absorption casing 1 plug-in slot 12, mounting panel 4 passes through the fix with screw to this installation boss 14 on, and this kind of connected mode not only makes the installation of absorption board 2 comparatively reliable, simultaneously, also is convenient for the change of whole absorption board 2. In addition, on the basis of the structure, a sealing gasket 3 or a sealing ring can be added between the mounting plate 4 and the mounting boss 14 for sealing. In other embodiments, if the adsorption plates 2 are not provided with connection plates, there may be installation errors at the positions of the plurality of adsorption plates 2 on the same side of the flue gas channel 11.
After the adsorption plates 2 with the above structures are installed, the flow of the thermal runaway flue gas in the adsorption shell 1 is wavy, so that the adsorption material 22 can fully adsorb impurities in the thermal runaway flue gas. The adsorbing material 22 may be specifically coated, smeared, or the like on the adsorbing surface 21 of the adsorbing plate 2. In the present embodiment, a mounting groove 23 is formed in the suction surface 21 of the suction plate 2, and the suction material 22 is fitted into the mounting groove 23. This kind of mounting means can realize the reliable installation of adsorbing material 22, can also not increase the thickness of adsorption plate 2, and the mode of being convenient for adsorption plate 2 adoption extrapolation is installed on adsorption shell 1. The adsorbent 22 is specifically made of a material capable of adsorbing impurities, such as activated carbon, molecular sieve, alumina, and the like. In the specific installation, the activated carbon is made into a block structure matching the shape of the installation groove 23 by pressing or the like, and then is embedded into the installation groove 23.
The embodiment also provides an energy storage device, which comprises at least one battery pack and a thermal runaway flue gas treatment device, wherein the battery pack comprises at least one battery. The explosion venting channel of the battery pack is communicated with the thermal runaway flue gas treatment device through a flue gas pipeline, and meanwhile, a battery thermal runaway flue gas pretreatment device is arranged between the explosion venting channel of the battery pack and the thermal runaway flue gas treatment device.
