Abstract

The utility model relates to a honeycomb ceramic checker brick, belonging to regenerative heat exchange element field, which mainly comprises a casing of the checker brick and a plurality of honeycomb pores distributed in the casing. The casing of the checker brick can be of regular polygonal prism shape or of round column shape, and the cross section of each honeycomb pore can be of regular polygon shape or of round shape; the material of the checker brick is corundum-mullite, and the utility model is used mainly for heat storage and heat exchange of industrial furnaces such as heating furnaces, annealing furnaces and shuttle furnaces. The utility model has the advantages of large heat exchange area, high heat exchange efficiency, uniform pressure of honeycomb pores, no deformation and crack and other advantages.

Description

The ceramic honey comb checker brick

One, technical field:

The utility model relates to a kind of regenerative heat-exchange element, particularly a kind of preparing heat-accumulating ceramic honeycomb lattice brick that is used for industrial furnaces such as process furnace, annealing furnace, shuttle-type stove, hotblast stove.

Two, technical background:

At present, being used for the regenerative heat-exchange body of industrial furnaces such as process furnace, annealing furnace, shuttle-type stove, mainly is two kinds of checker brick and solidspheres, and these two kinds of regenerative heat-exchange bodies are because heating surface is little, heat exchange efficiency is low, can not bring into play accumulation of heat effectively, the effect of heat exchange.And the existing ceramic honey comb checker brick that are used for purifying vehicle exhaust, although increased contact area effectively with gas, increased the catalysis area, but because the honeycomb hole generally only has 1.5 millimeters of less thaies, the too little and cross-sectional shape honeycomb hole of hole is a square, thereby the clean gas of contact gear ratio that can only be used to circulate, as vehicle exhaust, as the relatively dirty industrial gasses that are used to circulate, be easy to stop up hole and heat storage capacity is little, secondly, the cross section is that foursquare honeycomb hole mechanical stability is poor, when cold and hot gas alternately passes through, because rapid heating and cooling, be easy to make honeycomb pore wall strain cracking and damage, influenced heat exchange efficiency.

Three, summary of the invention:

For overcoming the deficiency of existing regenerative heat-exchange body and ceramic honey comb checker brick, it is bigger that the purpose of this utility model just provides a kind of honeycomb hole, and honeycomb hole cross-sectional shape is practical relatively flexibly, is difficult for rimose ceramic honey comb checker brick.

For achieving the above object, the utility model has adopted following technical scheme.

A kind of ceramic honey comb checker brick, mainly by the checker brick housing be distributed in the intravital honeycomb through hole of checker brick shell and constitute, described checker brick housing can be regular polygon prism or right cylinder, the shape of cross section that is distributed in the intravital honeycomb through hole of checker brick shell can be regular polygon or circle, the quantity of honeycomb through hole can be arranged arbitrarily according to the big or small wall thickness and the service requirements of checker brick, the wall thickness of checker brick housing and honeycomb through hole is 0.5 to 3 millimeter, and the main material of ceramic honey comb checker brick is diamond spars---mullite.

Owing to adopted such scheme, the utility model has not only increased the heat interchanging area of heat exchange body effectively, and hole is bigger, be difficult for making hole to stop up, can be applicable to effectively industrial furnace accumulation of heat and heat exchange owing to adopted hole cross section, improved the mechanical stability of honeycomb through hole as other shapes such as regular hexagons, stress is even, and pore wall is difficult for strain cracking.

Four, description of drawings:

The utility model is described in further detail below in conjunction with accompanying drawing.

Fig. 1 is the stereographic map of regular hexahedron housing of the present utility model and honeycomb pass;

Fig. 2 is the structural plan figure of regular hexahedron housing of the present utility model and honeycomb pass.

Five, embodiment:

Mainly a kind of ceramic honey comb checker brick of introducing are, checker brick housing 1 is a regular hexagon, and the honeycomb hole that is distributed in the checker brick housing 1 is through hole 2, and the shape of cross section of honeycomb through hole 2 is a regular hexagon.Ceramic honey comb checker brick described in the utility model are a kind of regenerative heat-exchange elements.Be mainly used in process furnace, annealing furnace, the gas accumulation of heat and the heat exchange of industrial furnaces such as rib formula stove, the main material of described ceramic honey comb checker brick is diamond spars---mullite, the ceramic honey comb checker brick are made up of checker brick housing 1 and the honeycomb through hole 2 that is distributed in the checker brick housing 1, the checker brick housing is the regular hexagon prism, the cross section of honeycomb through hole 2 is a regular hexagon, the wall thickness of checker brick housing 1 and honeycomb hole 2 is 0.5 to 3 millimeter, the size of honeycomb hole and quantity can be processed arbitrarily according to need of work, and the overall dimension of ceramic honey comb checker brick also can be adjusted arbitrarily according to worker's needs that spread.The housing of ceramic honey comb checker brick described in the utility model can also be the prism or the right cylinder of other shape; the cross-sectional shape of honeycomb hole can also be other Polygons or circle; in a word; the conversion of other Any shape, wall thickness, honeycomb pass all should belong to elementary factor of the present utility model and replace; be mentality of designing of the present utility model, should belong to protection domain of the present utility model.
