Catalyst random packing

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 [0001] The invention relates to a chemical catalyst packing, in particular to a catalyst random packing, which is mainly used in the catalytic rectification process of the chemical industry. Background technique [0002] In the prior art, most of the catalysts used in the chemical catalytic rectification process are arranged in the rectification tower in the form of structured packing. The bag is loaded between two layers of wire mesh and then rolled into a roll to form a cylinder. When used for catalytic rectification, the filler is vertically stacked on the filler support grid to form a catalyst bed. The disadvantage of this kind of structured packing is: there is a large space between the packing rolls, and the experiment found that the gas passes through this space to form a gas short circuit, and there is no good gas-liquid contact, so it cannot transfer mass well. . For this reason, some people also want to use random packing to overcome this shortco...

Problems solved by technology

The disadvantage of this kind of structured packing is: there is a large space between the packing rolls, and the experiment found that the gas passes through this space to form a gas short circuit, and there is no good gas-liquid contact, so it cannot transfer mass well.

For this reason, some people also want to use random packing to overcome this shortcoming of structured packing, but because the catalyst and packing shell are difficult to suspend and fix, resulting in complicated production and high cost, they have not been realized.
