Description

Energy storage cabinet and flue gas treatment device Technical Field The application relates to the technical field of energy storage, in particular to an energy storage cabinet and a flue gas treatment device. Background In the electrochemical energy storage industry, batteries (e.g., lithium batteries) are widely used in various fields due to their advantages of stable performance, long life, low cost, and the like. However, the battery is susceptible to thermal runaway under the influence of factors such as short circuit, overcharge, overdischarge, high-level environments, and the like. After thermal runaway of the battery, a large amount of combustible gas (such as hydrogen, carbon monoxide, methane and the like, simply referred to as flue gas) is generated, and when the combustible gas is accumulated in a limited space, a high explosion risk exists. The prior art generally adopts a smoke exhaust channel to exhaust the combustible gas generated after the thermal runaway of the battery. For example, in the energy storage cabinet, the cabinet body is internally provided with a smoke exhaust channel, an adsorbent bag for filtering gas is arranged in the smoke exhaust channel, after the battery in the cabinet body is out of control, the combustible gas can enter the smoke exhaust channel, and the combustible gas is filtered by the adsorbent bag and then is conveyed to the outside of the cabinet body, so that the risk of aggregation of the combustible gas in the cabinet body is reduced. However, in this arrangement, the position of the adsorbent bag in the smoke exhaust passage may be moved, which may easily block the explosion-proof valve, and there is a high safety risk. Disclosure of utility model The application provides an energy storage cabinet and a flue gas treatment device applied to the energy storage cabinet, so as to reduce the risk of blocking an explosion-proof valve after thermal runaway of a battery pack. In order to achieve the above purpose, the application adopts the following technical scheme: In a first aspect of the application, an energy storage cabinet is provided, comprising at least one adsorption device and at least one battery pack. The battery pack comprises a battery shell, an explosion-proof valve and a plurality of battery cores, wherein the battery cores are positioned in the battery shell, and the explosion-proof valve is arranged on the battery shell. The adsorption equipment includes the casing and is used for filtering gaseous adsorption piece, and the casing is including holding chamber, entry and export, holds the intracavity and is provided with first board, holds the chamber including the first cavity and the second cavity that are located the different sides of first board, entry and first cavity intercommunication, export and second cavity intercommunication. A plurality of first through holes are formed in the first plate and are communicated with the first cavity and the second cavity. The end parts of the explosion-proof valve, which deviate from the plurality of battery cores, extend into the first cavity through the inlets, and the absorption part is accommodated in the second cavity. In the energy storage cabinet provided by the application, after the battery Bao Re is out of control, gas such as hydrogen, carbon monoxide, methane and the like (short for flue gas) can be generated in the battery shell and can be sprayed out from the explosion-proof valve. Because the one end that the explosion-proof valve deviates from a plurality of electric cores stretches into in the first cavity through the entry, so from explosion-proof valve spun gas can get into in the first cavity to in the second cavity through the first through-hole on the first board, adsorb the filtration of absorbing member in the second cavity after, discharge adsorption equipment from the export. Through setting up first board, can prevent that the absorbing member from getting into in the first cavity from the second cavity, reduce the possibility that absorbing member blockked up explosion-proof valve in the first cavity to reduce the risk that explosion-proof valve blockked up after the battery package thermal runaway, thereby improve the security of energy storage cabinet. In some embodiments, a gap is formed between the end of the adsorbing member, which faces away from the plurality of electric cores, and the first plate, so that the explosion-proof valve is prevented from extending into the second cavity through the first through hole, and further, the situation that the adsorbing member blocks the explosion-proof valve due to the fact that the explosion-proof valve extends into the second cavity is prevented. In one embodiment, the adsorption device further comprises a second plate disposed between the outlet and the adsorbent member. The second plate is provided with a plurality of second through holes which are communicated with the outlet and the second chamber. The flue gas after bei
