Abstract
The invention relates to a catalyst random packing. The catalyst random packing comprises a packing shell and a catalyst packet placed inside the packing shell. The packing shell is provided with a cylinder. One end of the cylinder is provided with a block end cover. The cylinder wall of the cylinder is provided with at least a circle of inner oblique tongue pieces, wherein the inner oblique tongue pieces are uniformly arranged along the circumference of the cylinder wall. The inner oblique tongue pieces extend to the cylinder, and the tongue tips are toward the direction of the block end cover. According to the present invention, one end of the catalyst packet is blocked by the block end cover, and the other end of the catalyst packet is hooked by the barbs formed by the inner oblique tongue pieces, such that the catalyst packet is suspended and fixed in the packing shell, and can not prolapse due to the gas surging and the liquid surging, the problems of suspension and fixation of the catalyst and the packing shell are solved; due to the random characteristic of the packing of the present invention, the gas short circuit phenomenon of the whole bundle of the catalyst filler packet can be overcome, the specific surface area of the gas-liquid contact can be increased, the effect of the catalytic reaction can be improved, and the reactive rectification process is achieved well.
Description
Technical field
The present invention relates to a kind of chemical catalyst filler, especially a kind of catalyst random packing is mainly used in chemical industry catalytic distillation process.
Background technology
In prior art; The used catalyst of chemical industry catalytic distillation process mostly is that the form with structured packing is arranged in the rectifying column; The most frequently used is the structured packing of a kind of catalyst silk screen, is commonly called as the bale packing catalyst, and it is that catalyst is packed appendix between two-layer silk screen; Be rolled into volume then, form a cylinder.When being used for catalytic distillation, filler is erect and is piled up on the filler supportive grid, forms beds.The shortcoming that this structured packing exists is: depositing than large space between the volume of filler and the volume, gas straight-through and formation gas short circuit from this space is found in experiment, does not have good gas-liquid to contact, so good mass transfer.For this reason, have the people also to want to overcome this shortcoming of structured packing with random packing, but because of catalyst and filler shell be difficult to suspend fixing, cause making complicated, cost is higher, all fail to realize.
Summary of the invention
The objective of the invention is to the problem in the prior art; A kind of catalyst random packing is provided; It has solved the suspension fixation problem of catalyst and filler body preferably, makes the random packing of this catalyst can replace structured packing, eliminates the gas short circuit in the structured packing; Increase the touch opportunity and the time of gas, liquid and liquid and catalyst, improve gas-liquid mass transfer efficient and catalytic reaction conversion ratio.
To achieve these goals, technical scheme of the present invention is following:
It has a filler shell and a catalyst bag that is placed in this filler shell; Described filler shell has a cylindrical shell; End at this cylindrical shell is provided with a lattice shelves end cap; On the barrel of said cylindrical shell, be provided with the interior oblique tongue piece that a circle is circumferentially evenly arranged along barrel at least, described interior tiltedly tongue piece stretches out in cylindrical shell, and the tip of the tongue is towards the direction of lattice shelves end cap.
The further technical scheme of the present invention is following:
Described interior oblique tongue piece is axially arranged with two circles or many circles along barrel, and the interior oblique tongue piece mutual dislocation between enclosing and enclosing is arranged.
Described lattice shelves end cap at least by two or more along barrel circumferentially evenly arrange and from the barrel radially the inside curved arc ring in footpath of convex constitute.
Described lattice shelves end cap is circumferentially evenly arranged and is constituted from the radially tongue piece that barrel stretches to the center along barrel by a plurality of.
Characteristics of the present invention are following:
One, the present invention better fills out catalyst packing in the filler shell; One end is by the block of lattice shelves end cap; The hangnail that is formed by interior oblique tongue piece simultaneously tangles; The catalyst bag is suspended be fixed in the filler shell, can not solve the suspension fixation problem of catalyst and filler shell preferably because of gas, liquid spring up.Not only can react well, and realize the mass transfer function of random packing.
Two, because this filler is a kind of catalyst random packing; When it looses when piling up the catalytic rectifying tower section of rectifying column; Can not only overcome the gas short circuit phenomenon of structured packing, increase the touch opportunity and the time of gas, liquid and liquid and catalyst, but also can in catalytic reaction, carry out rectifying; Reach while the purpose of reacting, separating, gas-liquid mass transfer efficient and catalytic reaction conversion ratio are effectively improved.
Three, filler shell one end of this filler is with the block of lattice shelves end cap, the hangnail satchel that the other end forms with interior oblique tongue piece, and the filling that makes the catalyst bag is without capping, loads simple to operately, reduced the cost of manufacture of filler.

The specific embodiment
Referring to Fig. 1～3; It has a filler shell and a catalyst bag (the catalyst bag does not draw among the figure) that is placed in this filler shell, and described filler shell has a cylindrical shell 1, is provided with a lattice shelves end cap at an end of this cylindrical shell; On the barrel of said cylindrical shell, be provided with the interior oblique tongue piece 2 that a circle is circumferentially evenly arranged along barrel at least; In described tiltedly tongue piece 2 in cylindrical shell, stretch out, and its tip of the tongue is towards the direction of lattice shelves end cap, thereby forms the satchel hangnail; In said tiltedly the axle of tongue piece with barrel an angle is arranged, this angle can greater than 0 ° and less than 90 ° between adjustment, tongue piece has elasticity preferably thereby make in this tiltedly.In order to make this filler carry out gas-liquid contact better, described in tiltedly tongue piece 2 be axially arranged with two circles or many circles along barrel, this example provides the structure of two circles, and the interior oblique tongue piece dislocation arrangement between circle and the circle.Described cylindrical shell 1 can be curled by a sheet metal and constitute, and the interior oblique tongue piece 2 on its barrel can cut on this sheet metal, the mould punching press constitutes, and curling to axially dislocation butt joint of edge fit 4, with the tiltedly dislocation of tongue piece 2 arrangement in the position that achieves a butt joint; Described lattice shelves end cap can be an independent cover member, and then connects firmly together with described cylindrical shell 1; It also can be the disjunctor end cap that on cylindrical shell, directly forms; This example adopts the disjunctor end cap, it at least by two or more along barrel circumferentially evenly arrange and from the barrel radially the radially curved arc ring 3 of convex constitute.Such disjunctor end cap can directly cut on the sheet material of cylindrical shell that curls, the mould punch forming, so have the simple advantage of making.
Referring to Fig. 4, described catalyst bag is made the shape that matches with the volume of cylindrical shell 1, can do a net as shown in Figure 5 earlier; Pack into behind the catalyst, two ends tie or are stitched together, form a cylinder shape catalyst bag; Pack into then in the filler shell 1, finally form a catalyst random packing.
This example is on the architecture basics of embodiment 1, and its lattice shelves end cap adopts the disjunctor end cap of another kind of version, and it is circumferentially evenly arranged and constitute from the radially tongue piece 5 that barrel stretches to the center along barrel by a plurality of.This lattice shelves end cap also be suitable for being employed in curl directly cut on the sheet material of cylindrical shell, the mould punch forming, have the simple advantage of making equally.Other structure of this example is identical with embodiment 1.
