Described active catalyst (3) is graininess, and its diameter or peripheral minimum dimension are more than described stainless steel ripple The mesh diameter of silk screen (4) and flat screen (1).
Described active catalyst (3) is spherical, bar shaped, cube shaped or cylindrical particle.
The bale packing catalyst (2) is rolled into solid cylindrical shape, and its is a diameter of >=50 ㎜, its height is >=100 ㎜.
The bale packing catalyst(2)Active catalyst on cross section is uniformly distributed.
A kind of combining structure of the bale packing catalyst of described methanol oxidation, including tubulation, described tubulation internal diameter with The diameter of the bale packing catalyst (2) is consistent, and N number of bale packing catalyst is loaded from top to bottom in described row inner axial tube (2)。
Active catalyst (3) sendout in the tubulation is incremented by with the bale packing catalyst (2) for unit from top to bottom, Increased amplitude follows following rule:
K=(an+1-an)/an
an+1For anThe amount of the active catalyst of one layer of bale packing below;
anFor the amount of the active catalyst of N layers bale packing;
N=1,2,3,4,5,6......n natural positive integer;
Wherein k:0 < k < 1,
As k=1, active catalyst is to be uniformly distributed in as whole tubulation;As 0 < k < 1 then along tubulation axial direction Active catalyst is gradually increased in units of each bale packing, i.e., more arrives the bottom of reactor tubulation, each upper active catalytic of bale packing Amount contained by agent is more, and is uniformly increased.
Effect of the present utility model is as follows:
The utility model packs catalyst by stainless steel ripple silk net and the flat screen phase for being uniformly distributed active catalyst Superposition, which rolls, to be formed, the grain structure such as active catalyst design globulate, contained by tubulation axially each bale packing catalyst Active catalytic dosage is gradually increased, changes the physical arrangement of catalyst, significantly improves the distribution shape of reaction mass State and the type of flow, improve product quality, reduce impurity, reduce further energy consumption, material consumption, big for methanol oxidation industry Solid foundation has been laid in scale development and production.

Embodiment
Following examples are only to illustrate the utility model example to be clear, and not to reality of the present utility model Apply the restriction of mode.For those of ordinary skill in the field, other can also be made on the basis of the following description Various forms of changes or variation, and these belong to the obvious changes or variations that the utility model spirit is drawn and still located Among the scope of protection of the utility model.
As shown in Fig. 2 the utility model is a kind of bale packing catalyst 2 of methanol oxidation, it includes stainless steel corrugation Net 4, active catalyst 3, flat screen 1, described active catalyst 3 is evenly distributed on described flat screen 1, described Stainless steel ripple silk net 4 is tiled with it after active catalyst 3 for being superimposed and stating in clad residence, by border seal, using one end as axle center Roll into bale packing catalyst 2;Described active catalyst 3 is graininess, its diameter or peripheral minimum dimension be more than it is described not The mesh diameter of rust steel ripple silk net 4 and flat screen 1, to prevent spilling;Described active catalyst 3 be spherical, bar shaped, cube The bodily form or cylindrical particle multiple choices;The bale packing catalyst 2 is shown in Fig. 2 to be rolled into solid cylindrical shape, its is a diameter of >= 50 ㎜, it is highly >=100 ㎜;It is preferred that diameter >=80 ㎜, the ㎜ of height >=200;The further preferably ㎜ of diameter >=100, the ㎜ of height >=300; 3 doses of active catalytic on bale packing catalyst 2 cross section is uniformly distributed;The percentage by weight composition of the active catalyst 3 For: MOO3:60-78%, Fe2O3:20-39%, remaining composition are such as one of IIIA, IV A and VIII in the periodic table of elements Kind or two oxides:0.1-2.0%;The proportioning of described two oxides is 0.1-1:1, preferably Al2O3
