Zusammenfassung:	To provide an extraction device capable of reducing accumulation and adhesion of dust, reducing thermal loss of cement kiln, and stabilizing an operation of a chlorine bypass facility.SOLUTION: A chlorine bypass extraction device 90 comprises: an extraction pipe 12 which is coupled to a kiln tail part 52 and/or a rising duct 51 of cement kiln, and extracts a kiln gas 60 from an extraction hole 12a; and a coolant gas introduction part 16 for introducing a coolant gas 62 along a peripheral direction of the extraction pipe. The extraction pipe 12 has a dam shaped member 10 on which a notch 11 is formed at the extraction hole 12a.SELECTED DRAWING: Figure 2 【課題】ダストの堆積及び付着を低減すること、及び、セメントキルンの熱損失を低減することが可能であり、塩素バイパス設備の運転を安定化することが可能な抽気装置を提供すること。【解決手段】塩素バイパスの抽気装置９０は、セメントキルンの窯尻５２及び／又はライジングダクト５１に連結され、抽気口１２ａからキルンガス６０を抽気する抽気管１２と、その周方向に沿うように冷却ガス６２を導入する冷却ガス導入部１６と、を備える。抽気管１２は、抽気口１２ａに切り欠き部１１が形成された堰状部材１０を有する。【選択図】図２
