The invention discloses a gas-liquid distributor, which comprises a cover plate and a central tube. The central tube is arranged vertically, the cover plate is horizontally disposed above the central tube, the central tube comprises an inlet part and a liquid drop part, the liquid drop part is below the inlet part, the lower end of the central tube is a central tube outlet, inclined cutting is conducted on the central tube top, a space formed between an inclined incision generated by inclined cutting of the central tube top and the cover plate is the inlet part, multiple rows of metal strip-type screens are distributed along the axial direction of the central tube on the liquid drop part, and a jet mixing device is disposed below the central tube outlet. The gas-liquid distributor provided by the invention is mainly used for a fixed-bed hydrogenation reactor in petroleum refining and chemical industry. The gas-liquid distributor provided by the invention can distribute gas-liquid raw materials evenly on a catalyst bed in the fixed-bed hydrogenation reactor to make the raw materials in full contact with a catalyst so as to lower the temperature difference with a cross section of the catalyst bed, thereby enhancing the oil product quality and lowering the production cost.
