A process for preparing a reactor (), said reactor defining an opening () for the passage of a device for dispensing solid particles () suitable for charging the reactor with solid particles, the process comprising:&#x2014;providing a sensor support device () to which a sensor is attached, said sensor being intended for collecting information on the charging of the reactor,&#x2014;attaching the sensor support to a component of the reactor () different from the device for dispensing solid particles.

Sensor support for a reactor undergoing charging

The invention relates to a light-weight device for loading solid particles into an enclosure including at least one pipe () for the circulation of said solid particles and at least one movable element for controlling the fall velocity of the particles, which is designed to be slidably moved inside of said pipe (). The device further includes a plurality of identical guide plates () connected to each other by attachment means. Said at least one pipe () is made of a flexible material and each guide plate () has at least one through opening for receiving and guiding said at least one pipe () in a position in which the longitudinal axis of the pipe extends substantially perpendicular to the plane of each guide plate.

Light-weight device for loading solid particles

The invention relates to a device for loading solid particles into a vessel comprising: and also to a process and uses implementing the device.

Device and method for loading solid particles into a chamber

The invention relates to a device for loading solid particles into an enclosure, including: a means for supplying solid particles to be dispensed, which can be arranged on the top part of the enclosure to be loaded and which pours the solid particles in a substantially vertical manner into a feeding pipe (); a mobile device () disposed entirely or partially inside the enclosure and under the feeding pipe, including a central shaft () rotatably driven by a motor means () about a substantially vertical axis and deflector elements () having a substantially identical shape and being rotatably secured to the shaft (), preferably arranged in line with one another at different heights about the shaft () and pivotably connected thereto so that they can be raised, for example by centrifugal force; and a feeding pipe () at least partially surrounding said central shaft () and comprising at least one opening () for discharging the solid particles, which opening is provided on the horizontal or side wall thereof. The invention is characterized in that the device includes at least one deflector element () disposed on the rotatably driven shaft (), the width of said deflector element () close to the shaft () being less than that of the other deflector elements (), in particular the width of the element close to the shaft is smaller than that of the other deflector elements. The invention also relates to a use of said device and to a loading method involving said device.

Device for loading solid particles into an enclosure

The invention relates to a device for loading solid particles into a vessel, comprising:

Device for loading solid particles into a chamber

The invention relates to a device for reducing fouling in a tube () through which a fluid passes. The inventive device comprises a mobile rotary element () and a fixed bearing-forming element () which can be solidly connected to the upstream end of the tube (). In addition, the mobile element (), which is connected to the fixed element (), comprises an upstream trunnion-forming part () and a downstream turbulence-generating part () which is shaped such as to be rotated by the flow of the fluid in the tube (). The aforementioned upstream () and downstream () parts are connected to one another by means of an elongated flexible connector () that is deformable along the entire length thereof.

Device for reducing fouling in a tubular heat exchanger

The invention relates to a device for filling a chamber with a divided solid comprising a divided solid feeder hopper (), an exhaust chimney () fixed to said hopper or connected thereto by a supply conduit (), a motor unit () rotatably driving a shaft () which is substantially disposed in the direction of the exhaust chimney and at least one deflector member () which is mounted downstream of the output orifice(s) () of the exhaust chimney and is pivotable about sail shaft () in such a way that it angularly moves away therefrom due to a centrifugal force when said shaft () rotates. The shaft () is embodied in such a way that it is hollow and shaped in the form of a tube whose internal diameter is sufficient for passing a functional device () therethrough.

Device and method for loading a chamber with a divided solid

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 () which is placed inside the pipe, wound around a central axis () and whose width is such that a distance between the external edge () of the ramp () and the pipe () is less than the size of introducible solid particles. A method using the inventive device is also disclosed.
