Abstract
A cleaning device for cleaning an orifice in a condensate removal device that is capable of use while the condensate removal device is on-line, i.e. during operation. In one aspect, the cleaning device provides a reciprocally movable cleaning rod that can be retractably insertable into the orifice. This can be done without affecting the sealed volume defined around the orifice. In another aspect, the cleaning device includes a retractable hood or shield over the cleaning rod, to protect when not inserted in the orifice.
Claims16
A condensate removal device for mounting in a pipeline, the device comprising:
- an inlet connectable to the pipeline to receive a condensable gas flow;
- an outlet connectable to the pipeline downstream of the inlet, the inlet and outlet being disposed on a pipeline axis through the device;
- a condensate drainage channel providing fluid communication between the inlet and outlet, the condensate drainage channel having an entry port from which the condensate drainage channel extends in a longitudinal direction, and an orifice that is occludable by condensate flow therethrough to restrict condensable gas flow therethrough;
- an access opening facing the entry port from an upstream side thereof, the access opening being offset from the pipeline axis;
- a cleaning device for cleaning the orifice, the cleaning device comprising:
- a cap which is mountable in the access opening of the condensate removal device;
- and
- a rod carrier having a cleaning rod thereon, the cleaning rod being receivable in the orifice,
- wherein the rod carrier is reciprocally movable relative to the cap, and
- wherein, when the cap is mounted in the access opening, the cleaning rod is aligned with the orifice in the longitudinal direction, and the cleaning rod is retractably insertable into the orifice by moving the rod carrier in the longitudinal direction;
- and
- a shield mounted on the rod carrier, the shield being movable relative to the rod carrier between a first position in which a portion of the cleaning rod is covered by the shield and a second position in which the portion of the cleaning rod is exposed.
A cleaning device for cleaning an orifice of a condensate drainage channel in a condensate removal device, the orifice being occludable by condensate flow therethrough to restrict condensable gas flow therethrough, the cleaning device comprising:
- a rod carrier having a cleaning rod at one end;
- and
- a shield mounted on the rod carrier, the shield being movable relative to the rod carrier between a first position in which a portion of the cleaning rod is covered by the shield and a second position in which the portion of the cleaning rod is exposed,
- wherein the cleaning device is insertable into an access opening of the condensate removal device at an upstream end of the condensate drainage channel, wherein the shield is retractable to the second position to permit insertion of the cleaning rod through the condensate drainage channel into the orifice.

- an access opening facing the entry port from an upstream side thereof, the access opening being offset from the pipeline axis;
- and
- a cleaning device mountable on the access opening, the cleaning device comprising:
- a rod carrier having a cleaning rod at one end;
- and
- a shield mounted on the rod carrier, the shield being movable relative to the rod carrier between a first position in which a portion of the cleaning rod is covered by the shield and a second position in which the portion of the cleaning rod is exposed,
- wherein the cleaning device is insertable into the access opening of the condensate removal device, wherein the shield is retractable to the second position to permit insertion of the cleaning rod into the orifice in the longitudinal direction.
