Embodiment Construction

[0047] In order to better explain the present invention and facilitate understanding, the present invention will be described in detail below through specific embodiments in conjunction with the accompanying drawings.

[0048] like Figure 1~2 Shown: This embodiment discloses a vertical device for improving gas flow distribution in a blast furnace, which includes a furnace body 1 and a plurality of vertical ventilation elements 2 arranged inside the furnace body 1 .

[0049] The blast furnace 1 described here refers to the iron-making blast furnace. The improvement in this embodiment is mainly to provide a method for improving the air permeability of the blast furnace for the iron-making blast furnace in the prior art, improving the gas flow distribution in the furnace, and increasing the amount of pulverized coal. It is a device to improve the production efficiency of ironmaking.

[0050] The multiple vertical ventilation elements described here are all solid columnar struct...

Abstract

The invention belongs to the technical field of blast furnace iron making, and in particular, relates to a vertical device for improving coal flow distribution in a blast furnace. The vertical devicecomprises a furnace body, and multiple ventilation pieces arranged in the furnace body; the multiple vertical ventilation pieces are all solid columnar structural bodies; and the multiple vertical ventilation pieces are distributed at the top of the blast furnace in an array form, extend from top to bottom, and are inserted in a material column in the blast furnace by a period of distance. The vertical device for improving coal flow distribution in the blast furnace can improve the breathability of the material column of the blast furnace and reduce total pressure difference of the blast furnace to solve such problems as coal flow distribution and breathability of the material column, and improves the air blowing quantity and the yield under the precondition of guaranteeing invariable pressure difference of the material column to achieve the beneficial effect of improving the production benefit.

Description

technical field [0001] The invention belongs to the technical field of blast furnace ironmaking, and in particular relates to a vertical device for improving gas flow distribution in a blast furnace. Background technique [0002] The air permeability of the material column in the ironmaking blast furnace in the prior art is very poor, thus affecting the efficiency of ironmaking. [0003] If the gas permeability of the blast furnace material column can be improved, it will help to reduce the total pressure difference of the blast furnace. On the premise of keeping the pressure difference of the material column constant, the blast volume increases, and the output will also increase accordingly, which helps to improve production efficiency. Contents of the invention [0004] (1) Technical problems to be solved [0005] Aiming at the existing technical problems, the present invention provides a vertical device for improving the gas flow distribution in the blast furnace, whi...
