METHOD AND DEVICE FOR LOADING SOLID PARTICLES INTO A VERTICAL PIPE

摘要

A method is described in which an elastic fluid is brought into contact with a substance in the form of solid particles. This involves creating a substantially vertical elongated tubular closed zone (1) containing a charge of matter in the form of solid particles (5), while the volume of the closed zone is greater than the established charge volume of the solid particles (5). The upper restraining means (3) is installed at the upper end of the closed zone (1), while the upper restraining means (3) is permeable to the fluid, but adapted to restrain solid particles (5) in the closed zone (1). The follower means (4) is mounted for movement in a closed zone (1) under a charge of solid particles (5) to move upward from the lower end of the closed zone (1) in an upward flow of elastic fluid through the closed zone (1) at a speed above the threshold speed. In the method, the flow of the elastic fluid is directed upward through the closed zone (1) at a speed that is sufficient to lift the solid particles (5) upward towards the upper end of the closed zone and form a solid particle pillow (5) on the lower side of the upper restraining means ( 3). This speed exceeds the threshold speed for moving the follower (4) upward until it hits the lower side of the solid particle cushion (5). The invention also provides a device suitable for the implementation of this process, and a method for loading a substance in the form of solid particles, essentially into a vertical pipe. The international application was published together with an international search report.
