Abstract
A method for cleaning a plurality of drainpipes installed in a movable equipment by causing a flow of a cleaning solution through the drainpipes includes the steps of connecting provisional pipes to the plurality of drainpipes, feeding a cleaning solution into the provisional pipes and the drainpipes, and applying negative pressure suction force to the provisional pipes and the drainpipes to cause a flow of the cleaning solution in the opposite direction to a drain direction in normal use, to thereby clean the drainpipes.
Claims11
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.
