Description

Technical Field

[0001] The utility model relates to a cleaning device for a long straight waste pipe, belonging to the technical field of cleaning waste pipes of carbonizing furnaces. Background Art

[0002] During carbon fiber production, pre-oxidized fibers undergo carbonization reactions at temperatures between 400°C and 1500°C. This process cross-links the macromolecules within the fibers, transforming them into fused ring structures and increasing the carbon content of the fibers to over 92%. High-purity nitrogen is used as a protective atmosphere during the carbonization process, cracking elements such as nitrogen, hydrogen, and oxygen within the fibers. These elements are then removed from the carbonization furnace exhaust duct primarily as gases such as HCN, NH3, H2O, CH4, CO2, and CO. However, during fiber carbonization, waste solids are generated, primarily fiber lint and carbon dust. These waste solids accumulate in the carbonization furnace exhaust duct, blocking it and causing poor exhaust flow.

[0003] Carbonization furnaces with larger orifices can be cleaned manually on a regular basis. However, the long straight pipes of the carbonization furnace are not easy to clean. Since the pipes are long, it is not convenient to reach into the pipes to clean the entire pipe section, and it is also impossible to clean them completely. The workload is large, the working environment is poor, and the health of the cleaning staff is endangered.

[0004] In summary, the existing technology has obvious inconveniences and defects in actual use, so it is necessary to improve it. Utility Model Content
