Abstract
The utility model discloses a hollow perforated porcelain ball. The hollow perforated porcelain ball is of a hollow ball structure. The surface of the hollow ball is provided with an opening. The hollow perforated porcelain ball has advantages of high permeability, large void fraction, low specific gravity of the porcelain ball and the like. When the hollow perforated porcelain ball is filled to the top of a reactor, a great amount of settlings in the reactor can be accommodated, therefore, the problem of high pressure drop of the reactor is effectively solved, the operation period of a device is prolonged and the hollow perforated porcelain ball has obvious economic benefits.
Description
Technical field
The utility model relates to a kind of inserts that is used for field reactors such as petrochemical industry, sewage disposal, specifically a kind of hollow perforate Ceramic Balls ceramic material.
Background technology
At petrochemical industry, be extensive use of a kind of filler of porcelain ball as reactor, it has mechanical strength, acid and alkali-resistance and corrosion resistance preferably, and can improve the redispersibility of material in the reactor, reduce circulating resistance, further improve the filter effect of gas-liquid, but it is than great, hole is little, can only hold impurity by piling up the gap, after the oil product deposit stopped up the gap, reactor pressure decrease increased, and device must be stopped work and be handled.
In order to improve the volume dirt ability of porcelain ball, a large amount of improvements have been done in this area on porcelain ball profile, honeycomb Pored ceramic ball, the CN2837299Y that proposes as CN201053000Y proposes solid Pored ceramic ball, CN2550055Y and propose Lantern porcelain ball, CN2848852Y honeycomb porcelain ball, CN2413787Y and propose Pored ceramic ball, CN2762877Y and propose that the crown porcelain ball of protrusion of surface, CN2535119Y propose the light Pored ceramic ball of bubble, CN2360151Y proposes Slot ceramic ball.These futuramic porcelain balls are compared with pure solid porcelain ball very big improvement, and packing ratio is great, porosity is little but still exist, and holds the deficiency of dirty ability.
Summary of the invention
The utility model has designed a kind of new hollow perforate Ceramic Balls, this porcelain ball has that bulk specific weight is little, porosity is big, holds the strong advantage of dirty ability, can effectively reduce the reactor bed pressure drop, the conditioned reaction logistics distributes, and this hollow Pored ceramic ball has broad application prospects.
The hollow Pored ceramic ball of the utility model is the hollow ball structure, and the hollow ball surface has perforate.
In the hollow Pored ceramic ball of the utility model, the hollow ball diameter can be determined as required, is generally 3～80mm, preferred 5～20mm.The thickness of hollow ball is generally 2%～40% of hollow ball diameter, is preferably 5%～30%.
In the hollow Pored ceramic ball of the utility model, the perforate on hollow ball surface can be various suitable shape, is preferably circle, ellipse, polygon, bar shaped etc.The quantity of perforate specifically is provided with according to the diameter of hollow ball, is generally 2～100, is preferably 4～20.Percent opening (the long-pending ratio of external table of the gross area duty bulbus cordis of perforate) is 0.1%～30%, is preferably 1%～20%.
The hollow Pored ceramic ball of the utility model has more macroporosity and the dirty ability of appearance, is applicable to impure or easy incrustation reaction system, as residual oil hydrocatalyst bed top, and coker gasoline hydrogenation catalyst bed top, the sewage disposal system reactor is medium.
