This utility model relates to an anti-clogging reactor for the resource recovery and preparation of ammonium sulfate from high-concentration ammonia-containing waste gas. The reactor body includes an absorption zone and a crystallization zone from top to bottom, with the crystallization zone and the absorption zone connected. The absorption zone is located above the liquid surface, and the crystallization zone is located below the liquid surface. The top of the absorption zone has a tail gas outlet, and the bottom of the crystallization zone has a crystal slurry outlet. An external Venturi reaction zone is located below the absorption zone of the reactor body, connected to the reactor body. The Venturi reaction zone has an inlet for the ammonia-containing waste gas and an inlet for the circulating absorbent liquid. The external Venturi reaction zone forms a primary absorption, reducing the intensity of the absorption reaction within the reactor and significantly improving the anti-clogging capability.
