The present invention discloses a gas-liquid distributor, which comprises a cover plate, a center pipe and a flow breaking plate, wherein the center pipe is arranged vertically, the cover plate is arranged horizontally above the center pipe, the center pipe comprises an inlet part and a liquid descending part, the liquid descending part is arranged below the inlet part, plural rows of opening holes are distributed on the liquid descending part along the axial direction of the center pipe, the lower end of the center pipe is a center pipe outlet, the flow breaking plate is arranged horizontally below the center pipe outlet, the top portion of the center pipe is subjected to oblique cutting, the space formed by the oblique cutting port formed from the oblique cutting of the top portion of the center pipe and the cover plate is the inlet part, and a flow disturbance device is arranged inside the center pipe. According to the present invention, the gas-liquid distributor is mainly used for the fixed bed hydrogenation reactor in petroleum refining and chemical industry; and with the gas-liquid distributor, the gas-liquid phase raw material can be uniformly distributed on the catalyst bed layer inside the fixed bed hydrogenation reactor and completely contacts the catalyst, such that the temperature difference inside the catalyst bed layer cross section is reduced so as to improve the oil product quality and reduce the production cost.
