Abstract
The invention belongs to the technical field of extraction and purification processing equipment in the field of uranium purification and production, and particularly relates to a method for fixing sieve plates of a pulse sieve plate column. According to the method for fixing the sieve plates of the pulse sieve plate columns, transverse fixing of the sieve plates is achieved through a central rod, pull rods and the like so that a gap between a column body and a plate string can be reduced, and mass transfer is sufficiently achieved. Radial fixing of the sieve plates is achieved through the pull rods and pull rod pipe spacers so that it can be guaranteed that the sieve plates are not prone to deformation, and mixed mass transfer is stable. Longitudinal fixing of the sieve plates is achieved through central pipe spacers, so that it is guaranteed that the distances between the sieve plates are equal, and mixed mass transfer is stable.
