This invention provides an airlift loop reactor without the need for external gases, which comprises main reactor (1), gas circulation line (2), gas pump (3), jacket (4), gas inlet (5), gas outlet (6), flow guider (7), gas flowmeter (8), feed inlet (9) and discharge opening (10). It is characterized by: connecting the gas outlet (6) on top of the airlift loop reactor to the gas inlet (5) at the bottom of the reactor, and installing the gas pump (3) in gas circulation line (2), hence directly using the internal gases as the circulation impetus, so that gases are directed by the gas circulation line (2) back to the bottom of the reactor after flowing out from the top of the reactor and then re-ejected into the reactor by the gas pump (3) and used as circulation impetus again. Compared to common airlift loop reactors which use external gases as the impetus; the airlift loop reactor of the present invention effectively reduces the cost of using external gases and hence diminishes production costs. Therefore, it has very good prospects for industrial application.

Réacteur à agitation par circulation d'air n'exigeant pas source d'air externe comportant un corps principal de réacteur (1), une conduite de circulation tournante d'air (2), une pompe à air (3), une chemise prise en sandwich (4), une entrée d'air (5), une sortie d'air (6), un tube de guidage (7), un débitmètre d'air (8), un orifice d'alimentation de matériau (9), et un orifice de refoulement (10). Le réacteur ci-décrit se caractérise en ce que la sortie d'air (6) au sommet du réacteur à agitation par circulation d'air est raccordée directement à l'entrée d'air (5) dans le fond du réacteur, et que la pompe à air (3) est installée à l'intérieur de la conduite de circulation tournante d'air (2) pour que l'air du système de réaction soit utilisé comme énergie de circulation tournante directement par la pompe à air (3).
