Description

Solid catalyst filling assembly and filling method

Technical Field

The invention relates to the field of reforming reactors, in particular to a solid catalyst filling assembly and a filling method.

Background

In a 30kW high-power reforming reactor, the height of a catalyst filling cavity is about 1.2m, which far exceeds the depth that a human arm can extend into, while the shape of a solid catalyst is generally cylindrical, the outer diameter of the solid catalyst is tightly matched with the inner diameter of the filling cavity, and the catalyst cannot fall to the bottom due to the influence of friction factors and the like during filling.

Disclosure of Invention

The invention aims to provide a solid catalyst filling assembly and a filling method, which utilize a filling hammer to knock a catalyst to move downwards and judge whether the catalyst is filled in place or not according to scales on the filling hammer rod, thereby ensuring the tight filling of the catalyst and improving the filling efficiency of the catalyst.

The purpose of the invention is realized by the following technical scheme:

the utility model provides a solid catalyst loads subassembly, is including loading mallet and quartz cloth, and wherein the catalyst passes through quartz cloth parcel and drops into reactor and loads in the cavity, and the catalyst in reactor loading cavity is beaten through load mallet and is moved down, load mallet and be equipped with the mallet pole, and be equipped with the scale of judging whether the catalyst targets in place on the mallet pole.

Load the mallet and include mallet pole and mallet board, and mallet board level locates mallet pole front end, and the catalyst passes through mallet board strikes.

The bottom of the filling cavity of the reactor is provided with a catalyst supporting net.

A packing method according to the solid catalyst packing assembly, comprising the steps of:

the method comprises the following steps: measuring and weighing the catalyst;

step two: wrapping the catalyst with quartz cloth along the circumferential direction;

step three: catalyst is put into the reactor filling cavity and is knocked down by a filling hammer:

step four: judging whether the catalyst is filled in place or not according to the scales on the filling hammer rod, if so, drawing out the filling hammer, and putting the next catalyst wrapped with quartz cloth into the filling cavity of the reactor until the filling cavity is filled with the catalyst;

step five: and (5) packaging the reactor filling cavity.

The invention has the advantages and positive effects that:

1. the invention uses the filling hammer to knock the catalyst to move downwards, and can judge whether the catalyst is filled in place according to the scale on the filling hammer rod, thereby not only ensuring the tight filling of the catalyst, but also improving the filling efficiency of the catalyst.

2. According to the invention, the catalyst is wrapped by the quartz cloth which is high temperature resistant, corrosion resistant and soft in texture to fill the gap between the catalyst and the inner wall of the reactor filling cavity, so that the reactant is prevented from passing through the gap part to reduce the reaction efficiency.

3. According to the invention, the catalyst supporting net is arranged at the bottom of the filling cavity 1 of the reactor and is used for supporting the catalyst, so that the falling and collision of the catalyst are avoided.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

As shown in FIGS. 1-2, the invention comprises a filling hammer 2 and a quartz cloth 4, wherein a catalyst 3 is wrapped by the quartz cloth 4 and is put into a reactor filling cavity 1, because the catalyst 3 and the inner wall of the reactor filling cavity 1 are both hard solids and have a gap therebetween, a reactant passes through the gap to reduce the reaction efficiency, the invention adopts the quartz cloth which is high temperature resistant, corrosion resistant and soft in texture to wrap the gap between the catalyst 3 and the inner wall of the reactor filling cavity 1, and the catalyst 3 in the reactor filling cavity 1 is knocked to move downwards by the filling hammer 2 to fall on the bottom of the reactor filling cavity 1 or on the catalyst 3 adjacent to the lower side.

As shown in fig. 1, the loading hammer 2 includes a hammer rod and a hammer plate, wherein the hammer plate is horizontally arranged at the front end of the hammer rod for knocking the catalyst 3, and the hammer rod is provided with scales for assisting in judging whether the catalyst 3 is in place, in this embodiment, the effective length in the reactor loading cavity 1 is 1 meter, and the length of the monolithic catalyst is 0.1 m.

As shown in fig. 1, a catalyst support net 5 is provided at the bottom of the reactor filling chamber 1 for supporting the catalyst 3 to prevent the catalyst 3 from falling and colliding.

The working principle of the invention is as follows:

the filling method of the invention comprises the following steps:

the method comprises the following steps: the catalyst 3 is measured and weighed;

step two: wrapping the catalyst 3 by quartz cloth 4 along the circumferential direction, wherein the thickness of the quartz cloth 4 depends on the size of a gap between the catalyst 3 and the inner wall of the reactor filling cavity 1;

step three: catalyst 3 was charged into the reactor loading chamber 1, and catalyst 3 was knocked down by reciprocating the catalyst 3 with a loading hammer 2:

step four: judging whether the catalyst is filled in place or not according to the scale on the hammer rod of the filling hammer 2, if so, extracting the filling hammer 2, and putting the next catalyst 3 coated with quartz cloth 4 into the filling cavity 1 of the reactor until the catalyst 3 is filled in the filling cavity as shown in figure 2;

step five: the reactor filling chamber 1 is enclosed.
