Slag flushing and water vapor treatment system for blast furnace

The invention provides a slag flushing and water vapor treatment system for a blast furnace. The system comprises: a slag flushing unit connected with the slag outlet of the blast furnace and used forflushing slag generated in the blast furnace; a collecting unit movably arranged above the slag flushing unit and used for collecting water vapor generated by slag flushing water for flushing the slag in the slag flushing unit in a closed manner; a filtering unit arranged on the collecting unit and used for filtering the water vapor collected by the collecting unit; a condensing unit positioned at the outlet end of the collecting unit and used for condensing the water vapor filtered by the filtering unit; and a recovery unit connected with the condensing unit and used for collecting condensedwater condensed by the condensing unit. The system can collect the water vapor generated by slag flushing in a closed manner, so the collection effect of the water vapor is improved. 本发明提供了种用于高炉的冲渣水蒸气治理系统，该系统包括：冲渣单元，冲渣单元与高炉的出
