Device for reducing flue gas leakage in front of converter furnace

Abstract

The invention relates to a device for reducing out-leakage of furnace-front smoke of a rotary furnace. The device comprises a furnace-front smoke cover and a furnace-front protective door, wherein the furnace-front smoke cover is arranged close to the upper part of the furnace-front protective door; the furnace-front protective door comprises a protective door frame and a heat insulating plate which is arranged at the inner wall of the protective door frame; the furnace-front smoke cover comprises a side plate which is arranged close to the furnace-front protective door; the side plate comprises a first inclined segment arranged at the lower part; the first inclined segment is obliquely downwards arranged towards the furnace-front protective door; the heat insulating plate comprises a second inclined segment close to the first inclined segment; the second inclined segment and the first inclined segment are arranged in parallel and form a flue; a sealing mechanism is arranged at the upper end of the flue. In the device disclosed by the invention, the furnace-front smoke cover and the furnace-front protective door are respectively provided with the flue formed by the inclined segments in order to increase the contact area between the flue and smoke dust and reduce the rising speed of the smoke dust, so dust removal is facilitated. The sealing mechanism is arranged at the upper end of the flue so that overflowing of the smoke dust can be effectively reduced, and thus the furnace-front work environment can be improved.

Description

technical field [0001] The invention relates to a device for reducing flue gas leakage in front of a converter, belonging to the technical field of steelmaking. Background technique [0002] There is a lot of smoke and dust coming out in front of the converter during the production process such as mixing molten iron. Although there is a dust removal system, there is still smoke and dust coming out in the gap between the fume hood and the protective door in front of the furnace, causing pollution. [0003] Therefore it is necessary to design a device to reduce the leakage of flue gas in front of the converter to overcome the above problems. Contents of the invention [0004] The purpose of the present invention is to overcome the defects of the prior art and provide a device for reducing the leakage of flue gas in front of the converter, which can effectively reduce the amount of smoke and dust in front of the furnace and improve the working environment in front of the furn...
