Abstract

The utility model discloses grid type smoke uniformly dispensing equipment for a hot blast stove of a blast furnace. The utility model is characterized in that the grid type smoke uniformly dispensing equipment is arranged on the top part of a regenerator for the hot blast furnace; the plane surfaces of grids are crescent-shaped, and the lateral surfaces are inequilateral trapezoidal; the grids are composed of multilayer bar-shaped side bricks; the bar-shaped side bricks have a definite inner bevel angle towards one surface of the inner side of the regenerator; bar-shaped transverse bricks and vertical bricks are all alternatively laid in layers, and connecting fasteners are separated on the bar-shaped transverse bricks and the bar-shaped vertical bricks with a definite distance. The utility model has the advantages of less brick shapes, and simple processing and installation. When the hot blast stove is under large repair and medium repair, the utility model is convenient in use.

Description

Blast funnace hot blast stove is put with the grid type flue gas is all equipped

The utility model relates to blast funnace hot blast stove heat storage technology field, especially blast funnace hot blast stove and puts with the grid type flue gas is all equipped.

At present, to the shape (circle, eyes shape, apple shape) of blast furnace Cowper stove regardless of the combustion chamber, when the high-temperature flue gas stream that burner produced is flowed through the regenerator top, flue gas flow always is partial to the regenerator periphery, most of heat all passes to the checker brick of regenerator periphery, and want heated cold wind main air stream exactly via the inboard checker brick of the low regenerator of temperature near partition wall, make that being heated the interior heat of the peripheral checker brick of the higher regenerator of temperature can not get reasonable use, only accounts for about 80% chamber of hot-blast stove checker brick utilization ratio.

The purpose of this utility model is the defective that overcomes the heat exchange of above-mentioned blast funnace hot blast stove regenerator, provides a kind of blast funnace hot blast stove to put with the grid type flue gas is all equipped.

The utility model blast funnace hot blast stove is sketched with all equipped technology contents of putting of grid type flue gas.

A kind of blast funnace hot blast stove is put with the grid type flue gas is all equipped, it is characterized in that: all equipped top that is arranged on chamber of hot-blast stove of putting of grid type flue gas, raster plane is arranged and is crescent, the side is that scalene is trapezoidal, grid is made of multilayer bar brick, and bar shaped limit brick has 30-40 ° inner bevel to the inboard one side of regenerator; The horizontal brick of bar shaped, brick-on-end all are alternating layer to be put, and the horizontal brick of bar shaped, has at interval connector link above the brick-on-end.

Characteristics of the present utility model are: the brick type is few, processing and simple installation, and the big or middle Shi Junneng of repairing conveniently uses at hotblast stove.Owing to adopt lath brick, it is few that the regenerator lattice brick checkerwork cell is blocked, and kept original regenerator heating surface constant, improved the accumulation of heat utilization ratio of regenerator lattice brick.

Embodiment

Embodiment of the present utility model is the (see figure 1) of implementing like this.Blast funnace hot blast stove is put with the grid type flue gas is all equipped, the all equipped top that is arranged on chamber of hot-blast stove 2 of putting of grid type flue gas, one side of grid 1 floor plan 3 partition walls 4 in the combustion chamber is crescent, the side is that scalene is trapezoidal, grid 1 constitutes (see figure 2) by multilayer bar brick, bar shaped limit brick 5 is to the inboard inner bevel that simultaneously has 30-50 ° of regenerator, and the horizontal brick 6 of bar shaped, brick-on-end 7 all are alternating layer to be put, the horizontal brick 6 of bar shaped, the brick-on-end 7 top connector links 8 (seeing Fig. 3,4) that have at interval.

Claims

1. a blast funnace hot blast stove is put with the grid type flue gas is all equipped, it is characterized in that: all equipped top that is arranged on chamber of hot-blast stove of putting of grid type flue gas, raster plane is arranged and is crescent, the side is that scalene is trapezoidal, grid is made of multilayer bar brick, and bar shaped limit brick has certain inner bevel to the inboard one side of regenerator; The horizontal brick of bar shaped, brick-on-end all are alternating layer to be put, and the horizontal brick of bar shaped, keeping at a certain distance away above the brick-on-end has connector link.
