Title
(EN) SEPARATION PUMP
(FR) POMPE DE SÉPARATION
Abstract
(EN)
The invention relates to a separation pump (1) for pumping a fluid mixture (2) of gas (3) and liquid or suspension (4) and for separating gas (3) and liquid or suspension (4) from each other. The separation pump (1) comprising a rotatable drum means (10) for rotating fluid mixture (2). The rotatable drum means (10) having an inner wall (11) and an inner space (12). The rotatable drum means (10) being rotatable for causing liquid or suspension (4) of fluid mixture (2) to form a layer of liquid or suspension (4) on the inner wall (11) and for causing gas (3) of the fluid mixture (2) to migrate towards the axis of rotation (13). The separation pump comprises foam discharging means (15) for discharging foam (16) from the inner space (12) of the rotatable drum means (10). The foam discharging means (15) comprises a second outlet (17).
(FR)
L'invention porte sur une pompe de séparation (1) permettant de pomper un mélange fluidique (2) de gaz (3) et de liquide ou suspension (4) et de séparer le gaz (3) du liquide ou suspension (4). La pompe de séparation (1) comporte un moyen de tambour tournant (10) servant à faire tourner le mélange fluide (2). Le moyen de tambour tournant (4) est muni d'une paroi interne (11) et d'un espace interne (12) ; est apte à tourner pour amener le liquide ou suspension (4) du mélange fluide (2) à former une couche de liquide ou suspension (4) sur la paroi interne (11) et pour amener le gaz (3) du mélange fluide (2) à migrer vers l'axe de rotation (13). La pompe de séparation est pourvue d'un moyen (15) de décharge de mousse pour décharger la mousse (16) de l'espace interne (12) du moyen de tambour tournant (10) ainsi que d'une seconde sortie (17).
