To reliably remove impurities such as dust, nibs or the like contained in circulation liquid (such as coating material) with a simple structure in a pipeline washing device provided on pipeline facilities in which the circulation liquid accumulated in a storage tank is sent out to a liquid sending pipe by a pump.SOLUTION: A pipeline washing device includes: an air sending pipe 16 which arranges an air intake part 16a on a storage outer part of circulation liquid 3 and arranges an air discharge part 16b during storage of the circulation liquid 3; and an air supply machine 17 which turns air taken-in from the air intake part 16a of the air sending pipe 16 into air bubbles of millimeter size or more, or an air stream and ejects it from the air discharge part 16b. Therein, the air ejection part 16b of the air sending pipe 16 is proximately arranged within such a range that air ejected from the air sending pipe 16 for a suction end 6a of a liquid sending pipe 5(6,7,8) provided toward a storage tank 2 interior can be sucked.SELECTED DRAWING: Figure 1
【課題】貯槽に溜められた流通液をポンプにより送液管へ送り出す管路設備に対して設ける管路洗浄装置において、流通液（塗料など）中に含まれるゴミやブツなどの不純物を、簡単な構造により、確実に除去できる。【解決手段】流通液３の貯留外部に空気取込部１６ａを配置すると共に流通液３の貯留中に空気吐出部１６ｂを配置する送気管１６と、送気管１６の空気取込部１６ａから取り込まれる空気を空気吐出部１６ｂからミリサイズ以上の気泡又は空気流にして吐き出させる空気供給機１７とを有しており、送気管１６の空気吐出部１６ｂは、貯槽２内へ向けて設けられる送液管５（６，７，８）の吸い込み端６ａに対して送気管１６から吐き出された空気が吸い込み可能となる範囲内に近接配置されている。【選択図】図１
