Exhaust assembly and kiln system

The utility model relates to the technical field of new energy battery material production, and discloses an exhaust assembly and a kiln system, the exhaust assembly comprises an exhaust pipeline, and a hydrophilic air-repellent film is arranged in the exhaust pipeline. According to the exhaust assembly, the hydrophilic and hydrophobic film is arranged in the exhaust pipeline and located on the exhaust path of the exhaust pipeline, when exhaust gas passes through the hydrophilic and hydrophobic film, water vapor in the exhaust gas is condensed and exhausted through the hydrophilic and hydrophobic film, and dry gas such as oxygen is intercepted and can return into the kiln again, so that the effects of water passing and gas blocking are achieved; meanwhile, the heat taken away by the oxygen is reduced, and the heat loss is reduced. 本实用新型涉及新能源电池材料生产技术领域，公开一种排气组件及窑炉系统，排气组件包括：排气管道，所述排气管道中设有亲水疏气膜。在上述排气组件中，由于排气管道内设有亲水疏气膜，亲水疏气膜位于排气管道的排气路径上，当排气经过亲水疏气膜时，其中的水蒸气会经亲水疏气膜凝结排出，氧气等干燥气体则被拦截，可以重新回到窑炉内，以达到过水阻气的作用，减少氧气的浪费，同时减少氧气
