Technical field
The utility model relates to a kind of heat storage, specifically a kind of board-like ceramic heat storage body that is used on the industrial furnace heat-storage type burner.
Background technology
Regenerative combustion technology is the novel combustion technology of energy-conserving and environment-protective that is widely used at present on the industry industrial furnaces such as Ferrous Metallurgy, machinery, petrochemical industry, building materials, nonferrous metallurgy.Ceramic heat storage body is that heat-storage type burner is finished the intermediate carrier that flue gas waste heat recovery utilizes, by heat storage periodically accumulation of heat and heat release, heat transferred normal temperature combustion air or coal gas with high-temperature flue gas, realize the recovery of fume afterheat and the high temperature preheating of combustion air or coal gas, reach the purpose of high-efficient energy-saving environment friendly.This shows that heat storage is the critical component in the heat-storage type burner.Domestic and international widely used heat storage mainly contains ceramic heat-storing sphere and honeycomb heat accumulation body at present, and wherein honeycomb heat accumulation body mainly contains square and two kinds of checkerwork cell structures of regular hexagon.In actual applications, because interstitial channels is irregular between the Ceramic Balls heat storage, the long-time easily dry slag of back that uses, cause flow resistance big, reduced the organic efficiency of fume afterheat, simultaneously, because heat exchange area per unit volume is little, increased the arrangement space of regenerator, brought difficulty to practical application is installed.For thin-walled checkerwork cell structure honeycomb heat accumulation body, its straight channel structure, reduced flow resistance significantly, the thin-walled feature of heat storage has improved the heat exchange area per unit volume aspect of heat storage effectively, wherein, the square checkerwork cell more helps the raising of heat exchange area per unit volume, but problems such as the stress of checkerwork cell corner is concentrated, the dry slag of the slagging of retractory of thin-walled, passage, high-temerature creep cause honeycomb heat accumulation body short service life; Simultaneously, the dislocation in the front and rear row honeycomb heat accumulation body installation process causes honeycomb channel partly to stop up, and causes flow resistance to increase, and has influenced the heat exchange property of heat storage, and energy-saving effect significantly descends.At the problems referred to above, domestic patent " a kind of heat storage " patent No.: ZL98242840.5 provide a kind of sheet broached-tooth design heat storage, strengthened the anti-stick slag performance of heat storage, avoided the blockage problem of heat storage passage effectively, but zigzag structure, the stress that has aggravated heat storage concentrates and arris protrudes the erosive wear at position, simultaneously, at the eddy current that air-flow is horizontal to be produced after plunderring sawtooth, deterioration the heat convection performance; In addition, the general ceramic material radiance is low, is unfavorable for the hyperthermia radiation heat transfer intensification, thereby this structure is unfavorable for the raising of the heat storage prolongation in service life, unit volume heat transfer sheet area and the improvement of heat storage heat exchange property.
The utility model content
For solving existing in prior technology the problems referred to above, the utility model provides the board-like ceramic heat storage body that a kind of heat exchange property is good, flow resistance is little, heat exchange area per unit volume is big, emissivity is high.
The utility model to achieve these goals, the technical scheme that is adopted is as described below: described board-like ceramic heat storage body is connected to form successively by several protruding spherical crowns 1 and several recessed spherical crowns 2, is transition face 3 between described several protruding spherical crowns 1 and several the recessed spherical crowns 2; Described heat storage profile can be rectangle or foursquare platy structure; The both sides of described heat storage are respectively equipped with edge 4, can adjust heat storage channel cross-sectional area and flow resistance by the difference of the height H between protruding spherical crown 1 end face of thickness h and heat storage both sides of adjusting edge 4.
Further, described protruding spherical crown 1 and recessed spherical crown 2 are the spherical crown of solid angle less than 2 π sr; Protruding spherical crown 1 on the described heat storage on the same side is that wrong row distributes with recessed spherical crown 2, with this board-like heat storage center line symmetric arrangement.
Further, the surface of the protruding spherical crown 1 in described heat storage both sides, recessed spherical crown 2 and transition face 3 scribbles high radiant rate coating 5.
The utility model by the superimposed assembling of finishing heat storage in regenerator, when superimposed, can adopt the high temperature mud bonding superimposed at 4 places, the edge parallel with flow direction in use, also can be directly superimposed; But adopt the superimposed comprehensive integral that improves heat storage in the regenerator of bonding.The heat storage bonding of smearing mud by 4 positions, the edge parallel with flow direction is superimposed, has guaranteed the comprehensive integral of heat storage in the regenerator.
The utility model is convenient to the demoulding of compression molding by protruding spherical crown 1, the recessed spherical crown 2 solid angles structural design less than 2 π sr (surface of sphere) spherical crowns, has avoided the corner to protrude the position air-flow and has acutely washed away, and has delayed the damaged process of heat storage.The utlity model has rational in infrastructure, flow resistance is little, long service life, good, the Remarkable Energy Saving advantage of heat exchange property are applicable to the heat-storage type burner on the various industrial furnaces.

The specific embodiment
Specify the specific embodiment below in conjunction with Figure of description.
As shown in Figure 1, the described board-like ceramic heat storage body of present embodiment is connected to form successively by several protruding spherical crowns 1 and several recessed spherical crowns 2, is transition face 3 between described protruding spherical crown 1 and several the recessed spherical crowns 2; By protruding spherical crown 1, recessed spherical crown 2 solid angles structural design less than 2 π sr (surface of sphere) spherical crowns, be convenient to the demoulding of compression molding, avoided the corner to protrude the position air-flow and acutely washed away, delayed the damaged process of heat storage.Described heat storage profile can be rectangle or foursquare platy structure, and wherein, if adopt the tabular structure of rectangle, rectangular length direction is identical with flow direction.
Particularly, as shown in Figure 2, the both sides of described heat storage are respectively equipped with edge 4.Be, can adjust heat storage channel cross-sectional area and flow resistance by the difference of the height H between protruding spherical crown 1 end face of thickness h and heat storage both sides of adjusting edge 4 according to using needs with being appreciated that.
Further, described protruding spherical crown 1 and recessed spherical crown 2 are the spherical crown of solid angle less than 2 π sr; Protruding spherical crown 1 on the described heat storage on the same side is that wrong row distributes with recessed spherical crown 2, with this board-like heat storage center line symmetric arrangement.Mistake row by the protruding spherical crown 1 on the heat storage same side, recessed spherical crown 2 distributes, and has reduced the area of transition face 3 significantly, has improved the heat exchange specific area of heat storage unit volume.By protruding spherical crown 1 and recessed spherical crown 2 symmetric arrangement at heat storage ipsilateral streamwise center line, guaranteed the symmetry of passage top and the bottom structures, improved air-flow distributes in the passage the uniformity and the surface heat exchanging utilization ratio of heat storage.
Certainly, the protruding spherical crown 1 on the described heat storage on the same side also can although the in-line arrangement distribution is unfavorable for the raising of the heat exchange specific area of heat storage unit volume, can reduce the manufacture difficulty of heat storage for in-line arrangement distributes with recessed spherical crown 2.
