1. A regeneration device for activating a catalyst to prepare low-carbon olefins from an oxygen-containing compound, wherein the regeneration device comprises a first regenerator and a second regenerator;
the first regenerator comprises a second activation zone, a first activation zone, and a gas-solid separation zone from bottom to top;
the second activation zone axially communicates with the gas-solid separation zone;
the first activation zone is arranged on a periphery of a junction between the second activation zone and the gas-solid separation zone, and the first activation zone communicates with the second activation zone;
the first activation zone is an annular cavity;
n baffles are radially arranged in the first activation zone, and the n baffles divide the first activation zone into n first activation zone subzones;
a catalyst circulation hole is formed in each of n−1 of the n baffles, such that a catalyst entering the first activation zone flows circularly;
the first activation zone of the first regenerator is connected to the second regenerator through a first pipeline, such that the catalyst in the first activation zone is configured to be delivered to the second regenerator; and
the second regenerator is connected to the gas-solid separation zone of the first regenerator through a second pipeline, such that the catalyst in the second regenerator is configured to be delivered to the gas-solid separation zone.
