Abstract: The present invention discloses an airlift reactor assembly with a helical sieve plate, comprising a reaction tank, wherein a draft tube and a gas sparger are assembled in the reaction tank, the gas sparger is arranged just below an riser section of the draft tube, a helical sieve plate is arranged in the riser section of the draft tube, and a body of the helical sieve plate is helical upwards to guide a part of two/three-phase flow in the riser section, and the body of the helical sieve plate is provided with a plurality of sieve meshes to guide the remaining two/three-phase go through the helical sieve plate in the riser section and to break bubbles. The present invention gives consideration to both macroscopic mixing and microscopic mixing processes. In addition to driving liquid to circularly flow by using ejected gas, the helical sieve plate can be used for breaking large bubbles into small bubbles thereby effectively preventing the bubbles from coalescing, increasing gas holdup and increasing a volumetric oxygen transfer coefficient.
