Obviously, in the case of mutual constraints, there is no best in any aspect, but only a comprehensive optimum, because the increase in the heat exchange area per unit volume will inevitably lead to the reduction of the entity and the resulting decrease in heat storage capacity

Embodiment Construction

[0011] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Depend on figure 1 -Figure 5 shows that the structure of the present invention is a regular hexagon made up of 19-hole checker brick part 1a and 37-hole checker brick part 1b, and both 19-hole checker brick part 1a and 37-hole checker brick part 1b are of the same size Regular hexagonal cylinder, the first tapered lattice hole 2a is evenly and vertically opened between the two end faces of the 19-hole checker brick part 1a, and the first tapered grid hole 2a is uniformly and vertically opened between the two end faces of the 37-hole checker brick part. Two tapered lattice holes 2b, the lower end face of each checker brick is symmetrical to the center, and six first circular grooves 3a or second circular grooves 3b are arranged at an angle of 60° apart, plus the first central concave in the center The groove or the second...

Abstract

The invention relates to a combination checker brick with two types of different brick structures, which can effectively solve the problem of improving the heat exchange capability under the condition of the heat exchange area of the given unit volume of the heat storage checker brick, is a regular hexagon which consists of a 19-hole checker brick part and a 37-hole checker brick part, a conical lattice hole is respectively arranged between the two end surfaces of the 19-hole checker brick part and the 37-hole checker brick part, a total of seven grooves of round grooves and central grooves are arranged at the lower side of each checker brick, positioning bosses are arranged at the upper side of each checker brick and correspond to the round grooves alternatively, the hole pitch of the 37-hole checker brick part is 0.75 time of that of the 19-hole checker brick part, and the 19-hole checker brick part and the 37-hole checker brick part are mutually combined to form the combination checker brick. The combination checker brick fully realizes the airflow pressure regulating and flow equalizing functions and improves the heat transfer effect between the airflow and a lattice porous wall side, so convenience is brought to regulate the heat exchange capability of different upper and lower parts of a heat accumulator.

Description

technical field [0001] The invention relates to a combined lattice brick composed of two different brick types for a blast furnace hot blast stove. Background technique [0002] The hot blast stove checker brick is an important part used in the hot blast stove as a heat storage-heat transfer medium. It completes the absorption of heat energy and the quality of itself in a periodic heat exchange process through the heat exchange between the grid holes and the airflow Released, effectively transforming the enthalpy of high-temperature flue gas into the enthalpy of blast furnace hot blast. In the practice of using checker bricks, there are numerous checker bricks with different apertures and shapes. Lower the reasonable body to ensure sufficient heat capacity. Obviously, in the case of mutual constraints, there is no best in any aspect, but only a comprehensive optimum, because the increase in the heat exchange area per unit volume will inevitably lead to the reduction of the...
