This will cause great obstacles to the discharge of condensed water in the pipeline. Especially in winter when there is a lot of water, the pipeline needs to be frequently unblocked and cleaned. However, the workload of frequent unblocking is too large, and pipeline unblocking and cleaning generally requires the pipeline network to stop gas for maintenance.
[0003] Existing blast furnace gas is generally only cleaned by dry dust removal. With the development of low-temperature smelting technology, the alkali metal moisture content in blast furnace gas increases, the viscosity of surface gas increases, and it adheres to the inner wall of the pipeline after long-term operation, especially at the bends of the pipeline. The change in airflow direction will cause serious dust accumulation on the opposite pipeline, causing pipeline blockage, affecting the operation of the blast furnace. The blast furnace is forced to stop the wind in advance for maintenance, which not only reduces the production operation rate, but also increases the workload of unblocking and cleaning. Therefore, a blast furnace gas pipeline opening cleaning device is proposed to address the above problems. Utility Model Content
