摘要 |
<p>The invention concerns a reactor for producing biogas, comprising a reactor vessel (3), a feed pipe (1) for introducing organic material to be putrified and a biogas output pipe (4), and within said reactor vessel (3) mixing means for mixing the organic material to be putrified. The reactor for producing biogas comprises a rotatable gas floatation section (8b) which has been disposed in the lower part of the vertical reactor vessel (3) above the entrance port (1a) of the waste material supply pipe (1). The reactor vessel comprises at least three ports for removal of fractions of the organic material being putrified or of particles entrained therewith, gravitation separation being arranged to take place below the floatation section (8b), advantageously with structural components (8d) moving in said below-located part promoting the separation.</p> |
