Abstract
A cleaning apparatus includes a cable with spacers along the length of the cable for insertion into a tube with bends. Each of the spacers have a sphere-like body and have a diameter that is approximately the same as an inner diameter of the tube. Each neighboring pair of spacers are spaced apart from each other at approximately the same distance as the inner diameter of the tube. The cleaning apparatus is suited for passing through tubing within cracking furnaces and heat exchangers, which typically have many U-bends.
Claims11
A cleaning system for inner surfaces of tubing, the system comprising:
- a cable with spacers along the length of the cable for insertion into a tube with bends, each of the spacers having a sphere-like body and each of the spacers having at least two surfaces set within the body to define a pair of opposite-facing frusto-conical openings through which the cable passes, and a cleaning apparatus positioned on the cable amongst the spacers;
- a first mover configured to pull the cable within the tubing in a first direction;
- a second mover configured to pull the cable within the tubing in a second direction, opposite the first direction;
- a controller device in communication with both the first mover and the second mover, the controller device comprising memory storing a database, the database comprising at least a first entry that comprises a first point of interest associated with a first specified location within the tubing;
- and
- the controller device configured to at least:
- activate the first mover to pull the cable and the cleaning apparatus through the tubing;
- detect that the cleaning apparatus has passed the first specified location;
- activate the second mover to pull the cable and the cleaning apparatus backwards past the first specified location;
- and
- activate the first mover to pull the cable and the cleaning apparatus forwards past the first specified location.
