From the foregoing, the profile of the utility model checker brick is the inverse-T-shaped structure of positive six prismatic combinations, these checker brick have two regular hexagon end faces and orthohexagonal annular end face that is parallel to each other and varies in size, and the area sum of regular hexagon small end face and regular hexagon annular end face is the area that equals the regular hexagon large end face, have the through hole (checkerwork cell) of arranging by equilateral triangle between the checker brick parallel end faces, hole shape is taper, namely end face aperture is large and another end face aperture is little, intactly the perforate number is 19 on large end face, intactly the perforate number is 7 on small end face, and there is not complete perforate on the regular hexagon annular end face, perforate on the small end face and the perforate of annular end face are combined, consist of 19 perforates.
For this checker brick, because 19 complete checkerwork cells are arranged on the large end face, thereby except the checkerwork cell at center, the medullary ray that connects its six checkerwork cells on every side can consist of first regular hexagon ring, its 12 outer checkerwork cells can be linked to be second regular hexagon ring, the medullary ray that 12 checkerwork cells that cut half of its outside and six cut 2/3 checkerwork cell also can be linked to be the 3rd regular hexagon ring, the sideline of Here it is checker brick six prismatic sidelines or large end face.So 19 complete checkerwork cells, 12 half holes and 6 1/3 holes around adding, effectively flowing and the opening that conducts heat of checker brick, the hole inner-wall surface area sum that its effective heat transfer area is exactly these checkerwork cells, central recess just is arranged within first regular hexagon ring, and its width of rebate is the width of hexagonal rings for this reason, and its bottom land width is slightly less than the width of notch, 7 checkerwork cells can be ganged up mutually, and its cross section is the inverted trapezoidal shape.
When checker brick are mutually piled up or are piled up the composition heat storage, its mutual location is to adopt equilateral triangle to arrange the structure that locating convex block and detent cooperatively interact, the cross section of its locating convex block and detent is two prismatics that positive triangle forms, its seamed edge is the line at adjacent four checkerwork cell centers namely, because the existence of checkerwork cell, detent and locating convex block are not have quadrangular prismatic.Detent is that opening surface is large and the bottom surface is little in design, and locating convex block is that end face is little and the bottom surface is large; For cooperating between detent and the locating convex block, the bottom surface of detent is greater than the end face of locating convex block, and the opening surface of detent is greater than the bottom surface of locating convex block.Because the summit of hexagonal centre groove and the inner vertex of detent share, thereby so that 9 checkerwork cells that are connected with three detents also be interconnected with 7 checkerwork cells of central recess.
Adopt the mode of Heterogeneous Permutation to stack such checker brick, except effective Stability Analysis of Structures that has guaranteed to stack, the existence of hexagonal ring groove of also piling up out because of central recess and the stepped appearance checker brick of checker brick, realized the from top to bottom intercommunication of air-flow between the checkerwork cell, thereby effectively regulated the pressure distribution of air-flow, reached the homogeneity of air current flow in the checker brick heat storage.Because piling up flowing in the body at this checker brick, air velocity distribution becomes more even than the distribution that is flowing in air-flow in the checker brick that do not have central recess and ring groove, and the flow pattern in the checkerwork cell is also more complicated, thereby except the effective rate of utilization of heat storage effectively improved, the heat transfer between air-flow and checkerwork cell been significantly enhanced.Main is the diversity (referring to flow direction) that flows in the checker brick, has created favourable condition for realize the super-thermal insulating burning temperature in checker brick.
Adopt in use a kind of form of stacking to be placed in the regenerator, for the stability of stacking, here adopt the top centering of all three blocks of splicing checker brick to place checker brick, its six sides are corresponding parallel with six sides of following three blocks of checker brick respectively, this namely descends the stacking of one deck brick and last layer brick to place by this dislocation mode, and the location of stacking is to realize by locating convex block 8 is final with the mutual interlock of detent 7.If locating convex block and detent have the dislocation that differs 60 °, dislocation this moment is stacked and just can be hocketed between three layers of checker brick, is conducive to the stability of packing structure.If locating convex block is corresponding setting with detent, dislocation this moment is stacked and is hocketed between two-layer checker brick exactly; Its stability of piling up still can guarantee.Because the vertical section of the utility model checker brick is stairstepping (namely inverse-T-shaped), the result of alignment just forms orthohexagonal annular horizontal channel of a company, add the effect of central recess, the effect that is interconnected of checker brick checkerwork cell is just very good, and the gas channel of checkerwork cell is just more complicated.
During implementation, checker brick will be piled up in hotblast stove in a manner described, to enter the heat storage that checker brick form at the combustion period flue gas flow, state meeting that be interconnected of checkerwork cell this moment is so that the pressure of the air-flow by adjacent checkerwork cell progressively tends to balance, and the velocity distribution of correspondence will progressively become even.Because the effect of this checkerwork cell air-flow intercommunication that realizes by groove and the hexagon circuit that is communicated with, and the application of taper checkerwork cell, not only improved the through-hole rate of checker brick, and the interior flow pattern of the tube seat that can produce a kind of complexity, except helping to regulate stream pressure and the even velocity of flow, can also enter smoothly lower floor checker brick hole to guarantee it so that the dust in the flue gas is concentrated to the checkerwork cell centre because of the mass force effect, avoid accumulation and the bonding of dust in the groove; Simultaneously, the fluidised form of this complexity also makes the Convective Heat Transfer between itself and the checkerwork cell be able to significant reinforcement, is conducive to lower the whole height of heat storage.
Use this notch cuttype checker brick with central recess in the air-supply cycle, its effect is particularly outstanding.Because being subject to structural limitations sends in the process of hotblast stove at cold wind, cold air chamber does not have the effect that uniform air flow distributes at all, when inhomogeneous air-flow after the bottom enters checker brick, can only realize the intercommunication of checkerwork cell air-flow with the hexagon circuit that is communicated with and produce complicated mixed flow through the groove of checker brick, thereby the distribution of the air-flow on the heat storage section is become evenly step by step, and then improve the utilization ratio of checker brick and the heat transfer between enhancing air-flow and the checker brick.So no matter in the air-supply cycle or at combustion period, can both make it to obtain fully and effectively utilizing and bringing into play on the basis that changes the air-flow distribution effect of its enhancement of heat transfer with the notch cuttype checker brick of central recess.
The utility model proposes a kind of with offering the intercommunication of central recess realization checkerwork cell on the checker brick end face, and pass through stepped appearance six prism structures and strengthen the new texture checker brick that crossflow circulates, this checker brick of strengthening the crossflow circulation provide a kind of porous material or vesicular structure for realizing the application of multi-hole medium combustion technology on hotblast stove.
