Abstract

Nouveau procédé de régulation automatique de transport pneumatique de matière pulvérulente comportant une colonne d'alimentation au pied de laquelle se forme un talus d'éboulement, une enceinte d'expédition munie d'une paroi poreuse de fluidisation, de conduites de fluidisation et d'alimentation de gaz surpressé équipée d'un injecteur, de conduites destinées au transport, qui se caractérise par le fait que, pour provoquer une diminution de l'angle du talus d'éboulement, on fluidifie le matériau, on choisit pour un débit de matière voulu dans la canalisation d'expéditon, une pression de consigne Pf au-dessous de la paroi poreuse, en ce que s'établit au-dessus de ladite paroi une pression Pc - Pf dans l'enceinte d'expédition de sorte qu'à tout accroissement de Pc au-delà de Pf correspond une diminution de la circulation gazeuse à la pression Pf à travers la paroi poreuse, tandis qu à toute réduction de Pc en deçà de Pf correspond une augmentation de ladite circulation gazeuse.
