ABSTRACT:
An apparatus designed to efficiently and positively clean a main piping not only totally, but also partially by the reciprocation of a pig. The cleaning apparatus is provided with a launcher (4) for projecting a pig (1) and a catcher (36) for receiving the pig (1) at both ends of a main piping (37). A compressed gas is supplied from a feed nozzle of the launcher to thereby send the pig to the catcher (36). In consequence to the arrival of the pig, the compressed gas is discharged through a discharge nozzle (29) of the catcher (36), when the pressure is decreased and the pig is accordingly stopped. The decrease of the pressure is detected by a pressure sensor (33) of the launcher (4). When the pig arrives at the catcher (36), it is detected by a pressure sensor (33) of the catcher (36). The compressed gas is supplied from a feed nozzle (22) of the catcher (36) based on the detecting signal of the pressure sensor (33 ) of the launcher (4), to thereby send the pig towards the launcher (4). The reciprocating motion of the pig is executed by opening/closing electromagnetic valves of the launcher (4), catcher (36), main piping (37) and branch pipes (41a, 41b) by means of a controller.
