Problems solved by technology
[0002] With the intensification of blast furnace smelting, the industry pursues the production requirements of high blast temperature and low energy consumption. At present, domestic hot blast stoves generally have problems such as brick dropping, wind blowing, masonry tilting, and collapse in the hot blast stove structure, which affect normal operation.
At present, the air temperature that the hot blast stove can provide is 1000 ℃ ~ 1300 ℃. Increasing the hot air temperature is an important means to reduce the coke ratio and increase the coal injection ratio. normal production, and caused a serious waste of fuel and a decline in production output, and even caused the masonry to be damaged by irregular airflow.

Embodiment Construction
[0020] The present invention will be described in detail below in conjunction with accompanying drawing and specific embodiment:
[0021] Such as Figure 1-2 As shown, a brick type of diversion device includes a brick body 1, the section of the brick body 1 is a right-angled trapezoidal structure, the brick body a surface and the brick body d surface are parallel to each other, the brick body c surface and the brick body The e surfaces are parallel to each other, there is a brick body b surface with a certain inclination angle between the brick body a surface and the brick body c surface, and there are several tongue grooves 2 on the brick body d surface. The tongue and groove 2 is a ∩-shaped structure. The tongue and groove 2 are parallel to each other. The height and width of the tongue and groove 2 are the same. The d-surface of the brick body is an isosceles trapezoidal structure. The d side of the brick body is wide on the left and narrow on the right.

The invention discloses a brick type flow guide device which comprises a brick body. The section of the brick body is of a right-angled trapezoid structure. A face a and a face d of the brick body are parallel with each other. A face c and a face e of the brick body are parallel with each other. A face b inclined at a certain angle is arranged between the face a and the face c of the brick body. The face d of the brick body is provided with a plurality of parallel tongue grooves of an n-shaped structure. The heights of the tongue grooves are equal, and the widths of the tongue grooves are equal. The face d of the brick body is of an isosceles trapezoid structure. The face d of the brick body is provided with the wide left portion and the narrow right portion. The brick type flow guide device is reasonable in airflow mixing effect and flow distribution, high in heat stability and structural stability, long in service life and good in comprehensive performance, overcomes defects of an existing combustor, and is simple and practical in design, stable and reliable in effect, convenient to manufacture, use and maintain and beneficial to application and popularization.
Description
technical field [0001] The invention relates to the technical field of hot blast stove burners, in particular to a brick-type diversion device. Background technique [0002] With the intensification of blast furnace smelting, the industry pursues the production requirements of high blast temperature and low energy consumption. At present, there are common problems in domestic hot blast stoves, such as falling bricks, blowing wind, masonry tilting, and collapse, which affect the normal operation of the hot blast stove structure. At present, the air temperature that the hot blast stove can provide is 1000 ℃ ~ 1300 ℃. Increasing the hot air temperature is an important means to reduce the coke ratio and improve the coal injection ratio. The normal production was interrupted, and it caused a serious waste of fuel and a decline in production output, and even caused the vicious consequences of masonry being damaged by irregular airflow. [0003] According to the situation of some ...
