Bioreactor comprising a mixing chamber

摘要

The invention relates to a bioreactor (1) comprising a reactor vessel (41) having a mixing chamber (3) separated by a partition (44) from a reaction chamber (2) located generally above the mixing chamber (3), the mixing chamber (3) having an inlet system (4) for influent or a mixture of influent and recycled material, wherein the inlet system (4) has an outlet opening (60-64) in the mixing chamber (3). In an embodiment the partition (44) has an opening (66) forming a connection between the mixing chamber (3) and the reaction chamber (2), wherein the outlet opening (60-64) of the inlet system (4) is directed at the opening in the partition. In an embodiment the mixing chamber (3) has a skeleton for reinforcing the mixing chamber.

1. A bioreactor comprising:
a reactor vessel having a mixing chamber separated by a partition from a reaction chamber located generally above the mixing chamber, the mixing chamber having an inlet system for influent or a mixture of influent and recycled material; wherein the inlet system has an outlet opening in the mixing chamber, the partition having an opening forming a connection between the mixing chamber and the reaction chamber; wherein the outlet opening of the inlet system is directed at the opening in the partition; and wherein the inlet system comprises a downer connected to the mixing chamber for bringing recycled material from the higher regions of the reaction chamber back into the mixing chamber, wherein the partition forms a side wall of the mixing chamber, said side wall is placed on a floor of the reactor vessel, wherein the opening is arranged in the side wall, and wherein said side wall is tilted with respect to the floor of the reactor vessel at an angle between 45 degrees and 85 degrees, wherein the side wall extends diagonally upward so that a bottom surface of the mixing chamber is larger than a top surface of the mixing chamber, and wherein the mixing chamber occupies a small surface area, less than 50%, of the total surface area of a floor of the reactor.
