closed circulation airlift reactor without external gases

摘要

CIRCULATION AIRLIFT TYPE REACTOR CLOSED WITHOUT EXTERNAL GAS REQUIREMENT. The present invention relates to a closed circulation airlift type reactor without the need for external gases comprising main reactor (1), gas circulation line (2), gas pump (3), jacket (4), inlet (5), gas outlet (6), flow guide (7), gas flow meter (8), power inlet (9), and discharge opening (10). It is characterized by: connecting the gas outlet (6) at the top of the closed circulation airlift reactor to the gas inlet (5) at the bottom of the reactor, and installing the gas pump (3) in the circulation line (2 ), therefore directly using the internal gases as the circulation pulse so that the gases are directed by the gas circulation line (2) back to the bottom of the reactor after flowing from the top of the reactor and then ejected into the interior of the reactor. reactor by the gas pump (3) and used again as a circulation pulse. Compared to common closed-loop airlift reactors using gases such as thrust, the closed-loop airlift reactor of the present invention effectively reduces the costs of using external gases and thus decreases production costs. Therefore, it has very good probabilities of industrial application.
