REACTION DEVICE WITH AIR-LIFT TYPE INTERNAL CIRCULATION AND FERMENTATION PROCESS USING SAID DEVICE

The present invention relates to a reaction device with air-lift type internal circulation which includes: a vertical cylindrical volume; a vertical element positioned within said volume in such a wayas to form an interspace with the walls of said volume, having a cross-section which is circular and orthogonal to the vertical axis of the element and with a variable internal diameter along said axis, said element being denoted "draft tube"; at least one gas distributor positioned on the bottom of said device; said device being characterized in that: the ratio between the diameter of the internal vertical element and the internal diameter of the cylindrical volume ranges from 0.05 to 0.5, and the ratio between the height of the vertical element and the height of the cylindrical volume is less than 0.5. 本发明涉及种具有气升型内部循环的反应装置，其包括：竖直的圆柱形容积部；竖直元件，其以与所述容积部的壁形成内部空间的这样的方式定位在所述容积部内，所述竖直元件具有圆形的且正交于所述元件的竖直轴线的横截面，并且沿所述轴线具有可变的内径，所述元件被表示为"引流管"；至少个气体分配器，其定位在所述装置的底部上；所述装置的特征在于：所述内部竖直元件的直径和所述圆柱形容积部的内径之间的比率在0.05至0.5的范围内，并且竖直元件的高
