A cleaning hose conveying module is proposed for the simple and quick cleaning of flue gas tubes, with which the cleaning hose can be conveyed from a hose store into a hose guide. A hose cleaning means is formed by a rinsing and drying unit for a hose after its withdrawal from the flue gas tube.
Claims14
A device for the cleaning of flue gas passes between heat exchanger tubes of a boiler plant comprising:
- a cleaning hose, which can be inserted through an entrance in a flue gas pass,
- a hose store, for providing the cleaning hose outside the flue gas pass,
- a plurality of hose guides, configured to allow insertion of the cleaning hose into the flue gas pass, each of the plurality of hose guides extending from a roof of the boiler plant to a platform, each of the plurality of hose guides comprising, between the roof of the boiler plant and the platform, a first arc of larger than 30° and a second arc of larger than 30°, and
- a cleaning hose conveying module, with which the cleaning hose can be pushed from the hose store into a selected hose guide of the plurality of hose guides.
A method for cleaning of flue gas passes between heat exchanger tubes of a boiler plant with a cleaning hose, wherein the cleaning hose is unrolled from a hose store and inserted through an opening into a flue gas pass, wherein the cleaning hose is pushed using a cleaning hose conveying module from the hose store through a pipe-shaped hose guide into the opening, wherein a hose cleaner with a pneumatic blast unit and a spraying unit having nozzles which spray a cleaning fluid onto the cleaning hose is located between a platform and the cleaning hose conveyor module, and wherein the hose cleaner is arranged in such a way that when the cleaning hose is pulled out from the hose guide, the cleaning hose is first sprayed with the cleaning fluid via the nozzles and is then dried using the pneumatic blasting unit.
