Description

Open cell carrier

Technical field

The utility model relates to the catalyst carrier in the industrial towers such as petrochemical industry, in particular to a kind of open cell carries Body.

Background technique

Ceramic honey comb is the catalyst of carrier, main using honeycomb ceramic specific surface area is big, aeration resistance is small, regularity is strong The characteristics of, it is made by hand work, is that prepared ceramic raw material is placed in specific extrusion moulding machine, acted in pressure Be connected to the network body containing thousands of tiny ducts after squeezing out by mold down, by the strong rare earth metal of activity, transition metal, The dipping such as noble metal is coated in ceramic honey comb surface and by reduction roasting reaches various practical performances, be widely used in petroleum, Pernicious gas in the elimination production process of the industries such as chemical industry and filter out the processed of residue liquid in process of producing product Journey.Currently, main honeycomb substrate common problem is in the market: when honeycomb substrate after a period of use, due to whole It is entirely tiny honeycomb hole on the cross section of a carrier, the honeycomb hole (especially intermediate honeycomb hole) in carrier is easy resistance Plug, molding, cause honeycomb hole intermediate liquid velocity of liquid assets slow, and circulating resistance is gradually increased, and tower pressure drop increases, and such phenomenon is not It only will cause production efficiency reduction, and increase electric flux consumption, shorten the service life of honeycomb substrate, improve production cost.

Utility model content

For above-mentioned the problems of catalyst carrier in the prior art, the utility model provides a kind of compression strength Height, velocity of liquid assets are fast, and large specific surface area, honeycomb hole is not easy the open cell carrier blocked.

The technical problems to be solved in the utility model is adopted the technical scheme that: open cell carrier, it includes ontology, The ontology is cylindrical body, several honeycomb holes axially through ontology upper and lower ends, the honeycomb are provided on the ontology Hole forms reticulate body, and the aperture of perforation ontology upper and lower ends is provided in the reticulate body, and the maximum gauge of the aperture is this The 1/4~1/3 of body diameter, the aperture cross-sectional area are not more than the 1/5 of body cross-section area, and the diameter of ontology is in 30 millis Meter or less when, honeycomb hole wall (6) is with a thickness of 0.2-0.3 millimeters, and the diameter of ontology is at 30 millimeters or more -70 millimeters or less, bee Socket bore wall is with a thickness of 0.3-0.7 millimeters, and for the diameter of ontology at 70 millimeters or more, honeycomb pore wall thickness is 0.7-1.3 millimeters.

Further, the cross section of the aperture is triangle, circle, rectangular, regular hexagon.

Compared with prior art, the utility model has an aperture due to axially disposed on honeycomb ceramics to the utility model, and Reasonably define the maximum gauge of aperture and the area of aperture, the reasonable design pass of ontology diameter and honeycomb pore wall thickness System, both can ensure that the intensity of carrier, and the ratio between honeycomb pore specific surface area and aperture sectional area can be made reasonably to be matched, had made Liquid can not only obtain adequately absorption and filtration, purification, and can reduce liquid circulating resistance in carrier honeycomb hole, improve Velocity of liquid assets, honeycomb hole are not easy obstruction and molding, reduce tower pressure drop, to improve the service life of carrier, reduce production cost.

Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention, it combines and has below according to attached drawing The utility model is described in further detail in body embodiment.

As depicted in figs. 1 and 2, the open cell carrier, it includes ontology 1, the ontology aluminium oxide and titanium dioxide Silicon etc. is that primary raw material and auxiliary material are fired through ball milling, aging mud refining, molding drying and high temperature, and the ontology is in cylinder Body, several honeycomb holes 2 axially through ontology upper and lower ends are provided on the ontology, and the cross section of the honeycomb hole is three Angular, round or rectangular, honeycomb hole mesh number is generally 80-300 mesh, and the honeycomb hole forms reticulate body, among the reticulate body It is provided with the aperture 3 of a perforation ontology upper and lower ends, two or most three perforations ontology upper and lower ends can also be set as certainly Aperture, but the sum of area of all apertures should be no more than the 1/5 of body cross-section product, and the maximum gauge of the aperture is ontology The 1/4~1/3 of diameter, the maximum gauge and area for limiting aperture are the absorption effects in order to not influence honeycomb hole in carrier as far as possible Rate, in order to ensure the intensity of ontology, when the diameter of ontology is at 30 millimeters or less, honeycomb pore wall thickness is 0.2-0.3 millimeters, when For the diameter of ontology at 30 millimeters or more (containing 30 millimeters) -70 millimeters or less, honeycomb pore wall thickness is 0.3-0.7 millimeters, when this For the diameter of body at 70 millimeters or more (contain 70 millimeters), honeycomb pore wall thickness is 0.7-1.3 millimeter, 6 thickness of honeycomb hole wall with outside The ratio between 5 thickness of 4 thickness of wall and inner wall is 1:1.2~1.3:1.1~1.15.

Preferably, the cross section of the aperture is triangle, circle, rectangular, regular hexagon etc..

In use for some time, honeycomb hole can generate blocking and molding because of adsorbing contaminant to previous existing honeycomb substrate The case where, for this defect, the aperture bigger than honeycomb hole aperture is provided on carrier, in the absorption effect for not influencing carrier In the case where rate, the circulating resistance of honeycomb hole can be effectively reduced, improves flowing velocity, therefore reduce honeycomb hole plug and molding The case where occur, further reduce replacement carrier number, saved production cost.

Embodiment of above is merely intended for describing the technical solutions of the present application, but not for limiting the present application, although referring to specific embodiment The utility model is described in detail, those skilled in the art should understand that, it can be to the skill of the utility model Art scheme is modified or replaced equivalently, and without departing from the spirit and scope of the technical scheme of the present invention, should all be covered In the protective scope of the claims of the utility model.
