Abstract:
An apparatus for cleaning a plurality of drainpipes installed in a movable equipment by causing a flow of a cleaning solution through the drainpipes, the apparatus comprising:provisional pipes to be connected to the respective drainpipes so as to allow a flow of a cleaning solution in the opposite direction to a drain direction in normal use; a cleaning solution preparation tank for preparing and storing the cleaning solution; a cleaning solution feeding pump for feeding the cleaning solution into the provisional pipes and the drainpipes; a vacuum pump for causing a flow of the cleaning solution filled in the provisional pipes and the drainpipes in the opposite direction by applying a negative pressure suction force to the provisional pipes and the drainpipes; a gas-liquid separation tank for separating the cleaning solution after having cleaned the drainpipes by flowing the cleaning solution in the opposite direction into gas components and liquid components; and a cleaning solution suction pump for returning the liquid components of the cleaning solution separated in the gas-liquid separation tank into the preparation tank.
