Description

好ましくは、分離装置１０は、冷却気流３１を導入するための冷却気流入口３０と、冷却気流３１を放出するための冷却気流出口３２とを備える、冷却システムをさらに有する。冷却気流出口３２は、たとえば筐体１１の上面の中央領域に設置され、冷却気流入口３０は、筐体１１の周方向壁１２に対向するロータリ分離ユニット１４の外面上に設置される。したがって、冷却気流３１は、フィルタブロック１５を通過する再生流２７とは反対の径方向１８ｒに、ロータリ分離ユニット１４のフィルタブロック１５を通過する。冷却システムは、再生システムに隣接して、特にロータリ分離ユニット１４の回転方向２０において再生システムの後に設けられ、再生処理後にフィルタブロック１５を冷却する。 Preferably, the separating device 10 further comprises a cooling system comprising a cooling air inlet 30 for introducing the cooling air flow 31 and a cooling air outlet 32 for discharging the cooling air flow 31 . The cooling air outlet 32 is installed, for example, in the central region of the upper surface of the housing 11 , and the cooling air inlet 30 is installed on the outer surface of the rotary separation unit 14 facing the circumferential wall 12 of the housing 11 . The cooling airflow 31 thus passes through the filter blocks 15 of the rotary separation unit 14 in a radial direction 18r opposite the regeneration flow 27 passing through the filter blocks 15 . A cooling system is provided adjacent to the regeneration system, particularly after it in the direction of rotation 20 of the rotary separating unit 14, to cool the filter block 15 after the regeneration process.

任意に、バッフル５０は、変化可能に制御されるように構成されてもよい。さらに、気流入口２２は、任意に、流れ領域が変化可能に制御され得るように構成されてもよい。 Optionally, baffle 50 may be configured to be variably controlled. Additionally, the air inlet 22 may optionally be configured such that the flow area may be variably controlled.
