<p>The device comprises a support (20) and at least one basket (22A to 22E) carried by said support (20). The basket (22A to 22E) comprises an upstream apertured wall (60) and a downstream apertured wall (62) together defining an intermediate space (70) for receiving the solid product (24). The upstream apertured wall (60) defines, opposite the intermediate space (70), a feed passage (90) for the upstream flow, and the downstream apertured wall (62) defines, opposite the intermediate space (70), a discharge passage (92) for a treated flow. The upstream apertured wall (60) and the downstream apertured wall (62) are mounted in such a way that said apertured walls can be moved freely in relation to one another and in relation to the support (20), on a given expansion path.</p> |
