Abstract
The utility model relates to a honeycomb ceramic packing. The main outer shape of the honeycomb ceramic packing is a cuboid; the cross section of the honeycomb ceramic packing is an irregular square; evenly distributed honeycomb square through holes are designed on the cross section perpendicular to an axial direction; the bore diameter of each hole ranges from 1mm to 3mm; the thickness of the inner wall of each hole ranges from 0.2mm to 0.7mm; the thickness of a honeycomb ceramic outer wall is 2-3 times of that of the inner wall of each hole; evenly distributed grooves are arranged on the honeycomb ceramic outer wall; the width of each groove conforms to the bore diameter; the depth of each groove is a half to a quarter of the thickness of the honeycomb ceramic outer wall; and the thickness of each wall between two grooves is 2-3 times of the thickness of the inner wall of each hole. The honeycomb ceramic packing has the advantages of inexpensive and easily obtained raw materials, large specific surface area of products, more even gas and liquid distribution and the like, and can be used as a packing applied to the fields such as gas-liquid separating towers in chemical industry, bioreactors of waste water treatment and the like.
Description
Technical field
The utility model relates to a kind of ceramic honey comb filler that is used for chemical separating tower packing and bioreactor.
Background technology
Ceramic honey comb is a kind of functional porous material of developing in recent years, has obtained using widely in vehicle exhaust processing, industrial waste gas processing, heat storage type combustion stove.The application of ceramic honey comb at aspects such as petrochemical industry gas-liquid separation tower packing, wastewater treatment bioreactor fillers also received researcher's concern.Ceramic packing has excellent acidproof heat-proof performance, and the corrosion of various inorganic acids, organic acid and the organic solvent of ability except that hydrofluoric acid is applicable to the occasion of various high and low temperatures and severe corrosive.Compare the ceramic packing of other types, ceramic honey comb filler geometrical surface is bigger, and intensity is higher, and gas-liquid is more evenly distributed, and bed resistance reduces.
Existing ceramic honey comb mainly is the product of cordierite, and the selected raw material of its suitability for industrialized production all requires high-quality kaolin, talcum and aluminium oxide, causes cost higher.In addition, present ceramic honey comb product outermost wall is thicker relatively, and is generally smooth flat.This type of ceramic honey comb is as chemical filler, during regular filling, the dead band that place's gas-liquid all can't be passed through must occur between two blocks of adjacent fillers in knockout tower or the reactor, causes the gas-liquid skewness.Simultaneously, the specific area of ceramic honey comb should be increased as much as possible,, more gas-liquid contact area can be provided, better effects if because for chemical separating tower packing and bioreactor filler, specific area is big more.Present ceramic honey comb inwall is the smooth passage, and surface area only depends on its geometric jacquard patterning unit surface to provide, if can handle the ceramic honey comb inwall, produces nano level micropore, then can increase the specific area of ceramic honey comb filler greatly.
The utility model content
The purpose of this utility model is in order to solve above-mentioned weak point, the ceramic honey comb filler that a kind of cost of material is low, specific area big, gas-liquid is more evenly distributed to be provided.
The design feature of ceramic honey comb filler of the present utility model is: the main body profile is a cuboid, and cross section is irregular square, highly is 50～300mm, and the cross section length of side is 50～150mm.Cross section Design perpendicular to axis direction has equally distributed cellular through hole, and the hole is a square, and the aperture is 1～3mm, wall thickness 0.2～0.7mm in the hole.The ceramic honey comb outer wall thickness is 2～3 times of hole inwall, on equally distributed groove is arranged, recess width is consistent with the aperture, the degree of depth is 1/2～1/4 of a ceramic honey comb outer wall thickness, wall thickness is 2～3 times of hole inwall between groove.The groove of ceramic honey comb filler outer wall both can have been eliminated the dead band between adjacent filler, and gas-liquid is more evenly distributed, and also can increase the geometrical surface of filler.
Ceramic honey comb filler of the present utility model prepares by the following method: gangue, magnesite and talcum are after crushed, add sesbania powder expanding agent, after water and glycerine mix, after pugging, old, extrusion modling, drying, calcining, obtain ceramic honey comb, ceramic honey comb after will calcining is again put into 20%～50% oxalic acid solution and is boiled, and keeps 2～4h.
The utility model is owing to adopt gangue as primary raw material, and production cost is lower.And the carbon that contains in the gangue becomes gas in calcination process overflows, and has increased the micropore quantity in the ceramic honey comb inwall.Adding sesbania powder expanding agent and carrying out post processing with oxalic acid also can increase quantity nanometer level microporous in the ceramic honey comb inwall greatly, thereby the specific area that makes the ceramic honey comb filler is up to 80～260m

Specific embodiments
Embodiment 1
To mix after gangue, magnesite, talcum and the weighing of sesbania powder, mixture usefulness gas grinding machine is ground into fine powder, after adding water and glycerine and stirring, after pugging, old, extrusion modling, drying, calcining, boil 2h with 50% oxalic acid again and promptly get the ceramic honey comb filler.As shown in Figure 1, gained ceramic honey comb filler is a cuboid, and cross section is irregular square, highly is 150mm, and the cross section length of side is 50mm.Cross section Design perpendicular to axis direction has equally distributed cellular through hole 1, and the hole is a square, and the aperture is 2mm, and the thickness of hole inwall 2 is 0.5mm.The thickness of ceramic honey comb outer wall 5 is 1.5mm, on equally distributed groove 3 is arranged, recess width is 2mm, the degree of depth is 0.5mm, the thickness of groove partition 4 is 1.5mm.
Claims (2)
1. ceramic honey comb filler, it is characterized in that its main body profile is a cuboid, cross section is irregular square, highly be 50～300mm, the cross section length of side is 50～150mm, Cross section Design perpendicular to axis direction has equally distributed cellular through hole, the hole is a square, the aperture is 1～3mm, and wall thickness 0.2～0.7mm in the hole, ceramic honey comb outer wall thickness are 2～3 times of hole inwall, on equally distributed groove is arranged, recess width is consistent with the aperture, and the degree of depth is 1/2～1/4 of a ceramic honey comb outer wall thickness, and wall thickness is 2～3 times of wall thickness in the hole between groove.
