Abstract
The utility model discloses a heat exchange brick, belongs to the field of heat exchange of metallurgical systems, and solves the problem of low heat exchange efficiency of an original airflow and a perforated brick. The utility model relates to a regular hexagonal grid-hole brick which comprises an upper boss, an airflow redistribution gap, a vent hole, a gas diversion hole and a lower boss, and is manufactured by adopting high-alumina or SiC material hot pressing; the vent holes are 20-30 circular holes with the diameter of 15-150 mm, are spaced by 5-10 mm, and are symmetrically and evenly distributed on the upper surface and the lower surface of the heat exchange brick according to the central axis; when the heat exchange brick is installed, the lower boss of the upper heat exchange brick is embedded in the upper boss of the lower heat exchange brick, so that the staggered arrangement of the air vents of the upper heat exchange brick and the lower heat exchange brick is ensured; in production, airflow enters the vent holes after being redistributed through the airflow redistribution gaps and the air distribution holes, and the heat exchange efficiency of the airflow and the perforated bricks is improved.
Description
Technical Field
The utility model belongs to the field of heat exchange of metallurgical systems.
Background
The heat exchange technology is common in the field of ferrous metallurgy, for example, a blast furnace hot blast stove heats cold air to 1200 ℃ by utilizing a combustion heat storage technology, and the principle is that fuel is combusted to generate high-temperature flue gas, a checker brick of the hot blast stove is heated, the cold air is discharged out of the hot blast stove after being cooled, and then the cold air is reversely heated into hot air required by the blast furnace through the checker brick of the hot blast stove. Because the air holes of the checker brick are directly communicated, the airflow resistance is small, and the heat exchange effect is poor.
Disclosure of Invention
The utility model relates to a heat exchange brick, in particular to a regular hexagonal grid hole brick, which comprises: the upper boss, the airflow redistribution gap, the vent hole, the gas shunting hole and the lower boss are manufactured by hot pressing high-alumina or SiC materials. The vent holes are 20-30 circular holes with the diameter of 15-150 mm, the distance is 5-10 mm, and the vent holes are symmetrically and evenly distributed on the upper surface and the lower surface of the grid hole heat exchange brick according to a central shaft. When the heat exchange brick is installed, the boss at the lower part of the upper heat exchange brick is embedded in the boss at the upper part of the lower heat exchange brick, so that the staggered arrangement of the upper and lower heat exchange brick air vents is ensured. In production, airflow enters the vent holes after being redistributed through the airflow redistribution gaps and the air distribution holes, and the heat exchange efficiency of the airflow and the perforated bricks is improved.

Detailed Description
The object of the utility model is achieved, as illustrated in the description accompanying fig. 1, by the following specific embodiments:
(1) the regular hexagon lattice hole heat exchange brick is manufactured by hot pressing high-aluminum or SiC materials.
(2) The side length of the heat exchange brick is 100-600 mm, and the height of the heat exchange brick is 100-600 mm.
(3) The height of a boss 1 at the upper part of the heat exchange brick body is 10-50 mm, and the thickness of the boss is 15-40 mm; the height of the boss 5 at the lower part is 10-50 mm, and the edge distance between the boss and the heat exchange brick is 16-41 mm.
(4) The edge of the air flow redistribution gap 2 and the edge distance of the heat exchange brick are 25-100 mm, and the depth is 20-50 mm.
(5) The gas distributing holes 3 are located at the center of the side length, and are 25-100 mm long, 50-100 mm wide and 30-100 mm deep.
(6) The vent holes 4 are 20-30 circular holes with the diameter of 15-150 mm, the distance is 5-10 mm, and the vent holes are symmetrically and evenly distributed on the upper surface and the lower surface of the heat exchange brick according to the central axis.
When the heat exchange brick is installed, the lower boss 5 of the upper heat exchange brick is embedded in the upper boss 1 of the lower heat exchange brick, so that the upper and lower heat exchange brick air vents 4 are arranged in a staggered manner; the gas flow enters the vent holes 4 after being redistributed through the gas flow redistribution gaps 2 and the gas distribution holes 3 in the production, so that the heat exchange efficiency of the gas flow and the grid hole bricks is improved.
