Abstract

The invention discloses a converter movable hood flexible ring mechanical sealing device and a sealing method. The device comprises a fixed flue, a movable hood and a protective flange fixed on the upper end of the movable loop. The movable loop is sleeved outside the fixed flue. The protective flange is provided with a flexible ring for sealing the annular air duct between the protective flange and the fixed flue. The invention has simple structure, avoids the pipeline and valve block facility necessary for nitrogen gas or steam sealing. The invention uses cheap seal ring and simple mechanical means to solve the seal problem of the converter movable hood, thus achieving good sealing effect, reducing the construction investment and production operating cost, and improving the recovered coal gas quality.

Description

Mechanical sealing device and sealing method of flexible ring of converter movable fume hood technical field The invention relates to a sealing device and a sealing method, in particular to a flexible ring mechanical sealing device for a converter movable fume hood and a flexible ring mechanical sealing method for a converter movable fume hood. Background technique In the production of steelmaking converters, due to the requirements of gas recovery and process technology, the movable hood above the furnace mouth not only needs to be able to move up and down along the vertical section below the fixed flue of the furnace mouth, but also needs to control the movement of the movable hood within the lifting stroke. The annular gap formed between the fixed flues performs good dynamic and static sealing. Although the currently known nitrogen or steam sealing technology for the movable hood of the converter is an advanced technology to replace the previous water sealing technology...
