Technical Field

[0001] The utility model relates to the technical field of blast furnace gas pipeline drainage equipment, in particular to a blast furnace gas pipeline and drainage pipe connecting device. Background Art

[0002] Blast furnace gas comes out from the gas downcomer on the top of the blast furnace and enters the downstream users after gravity dust removal and gas dry dust removal. As the gas temperature continues to drop, condensed water in the gas continues to precipitate. If it is not discharged in time, the condensed water contains a large amount of chloride ions, which will seriously corrode the gas pipeline and downstream user equipment, posing a great hidden danger to production safety.

[0003] The utility model patent application document with publication number "CN220303096U" discloses a blast furnace gas pipeline and drainage pipe connecting device, which is mainly composed of a blast furnace gas pipeline, an outer plate, an inner plate, a drainage pipe and a bottom plate. The technical scheme manufactures and installs a hollow funnel-shaped structure welded by two outer plates, two inner plates and a bottom plate with the blast furnace gas pipeline according to the installation position relationship designed according to the depth of water accumulation, so that the effective intersection area of ​​the two is increased and the drainage effect is better. The funnel-shaped structure can be customized according to the designed proportion as the outer diameter of the gas pipe changes.

[0004] The blast furnace gas pipeline and drain pipe connecting device disclosed in the above document has the following defects: the blast furnace gas pipeline, connecting pipeline and drain pipe are welded together, however, condensed water will slowly corrode the gas pipeline, connecting pipeline and drain pipe during long-term use. When the connecting pipeline is corroded and condensed water leaks, the connecting pipeline cannot be replaced separately, resulting in waste of resources and poor practicality.

[0005] It can be seen from this that the existing blast furnace gas pipeline and the drainage pipe do not have a good connection structure, and it is necessary to improve the existing deficiencies and provide a blast furnace gas pipeline and drainage pipe connection device. Utility Model Content
