Problems solved by technology

The device described in said application is completely satisfactory both in terms of charging speed and filling quality, but it has the disadvantage of having a number of problems such as excessive volume
In fact, the curved or helical shape of the device and the relatively rigid material of the tube make its transport, installation and disassembly through the reactor manhole difficult

Embodiment Construction

[0048] [48] ​​FIG. 1 shows a section of a device according to the invention with a helical ramp 2 fixed on and coiled around a central axis 3, so that The central axis is here a solid rod. The spiral chute can be glued or welded to the center post through its bottom. The helical structure is surrounded by a flexible tube 1 . The diameter of the flexible tube is such that the distance between the outer edge 4 of the helical chute and the tube is smaller than the size of the particles to be loaded. The outer edge 4 of the chute 2 may be in frictional contact with the inner surface of the flexible tube.

[0049] [49] FIG. 2 schematically shows the connection between two shaft elements 6 which each support a helical ramp 2 and are separated by an intermediate element 5 . The intermediate element 5 is connected to the shaft element 6 by means of a hinge 8, for example a ring-hook system, which facilitates and speeds up the installation and / or removal of the device. In the area ...

Abstract

The invention relates to a device for introducing solid particles into a vessel, in particular into a chemical reactor which comprises a pipe, preferably flexible and cylindrical, through which said particles flow from the top downward and is characterised in that it also comprises at least one helicoidal ramp (2) which is placed inside the pipe, wound around a central axis (2) and whose width issuch that a distance between the external edge (4) of the ramp (2) and the pipe (1) is less than the size of introducible solid particles. A method using the inventive device is also disclosed.

Description

technical field [0001] [01] The present invention relates to a device and method for loading solid particles into cavities, especially large-sized cavities up to tens of meters in height, and the solid particles must maintain their physical integrity ( intégritéphysique). [0002] [02] The apparatus and method according to the invention are used in particular for loading solid particles into a fixed-bed reactor of the chemical or electrochemical, petroleum or petrochemical type, wherein the solid particles It may be in the form of beads, granules, cylinders, flakes, rods or any other form, but smaller in size. The solid particles are particularly fragile solid particles, which are difficult to withstand free fall from a height of several meters. [0003] [03] The present invention will be described below with respect to an inertial ball (bille inerte), generally made of ceramic material, loaded on a chemical reactor of the fixed catalyst bed type. However, the Applicant int...
