| 摘要 |
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 is such 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.
