The invention discloses a suction type rotational flow mixing distributor which mainly comprises a rotational flow mixing cavity, a downcomer and a rotational flow distribution cavity and is integrally in a vertical dumbbell shape, the rotational flow mixing cavity located on the upper portion is communicated with the rotational flow distribution cavity located on the lower portion through the downcomer in the middle, and a spiral mixing channel is formed in the rotational flow mixing cavity. A radial distribution channel is arranged in the rotational flow distribution cavity; a bubble cap, a conical barrel or a spiral blade and other reinforced mixing elements are arranged in the downcomer; the suction type rotational flow mixing distributor can strengthen the mass transfer process and improve the heat transfer efficiency, and is suitable for being used between catalyst bed layers of a large-diameter down-flow reactor. Meanwhile, the invention further discloses gas-liquid mixing and distributing equipment. 本
