摘要： The present invention discloses an external loop slurry reactor, comprising a gas-liquid integrated distributor, a riser, a degassing zone, a solid-liquid separation circulation unit, and a storage tank. When the reactor works, reactants are injected into the riser through the gas-liquid integrated distributor; the slurry mixes and flows upwards to the degassing zone at the top for gas removal, and a large number of bubbles are removed. The slurry with catalyst particles then enters a downcomer and flows downwards. The slurry flows into a first-stage hydrocyclone and a multi-stage hydrocyclone in sequence for solid-liquid separation. The diameter of the first-stage hydrocyclone is larger than that of the multi-stage hydrocyclone. The separated solid particles flow back into the riser to continue to participate in the reaction.
