Abstract

The invention provides a gas-liquid distribution disk for a hydrogenation reactor. The gas-liquid distribution disk comprises a disk plate, wherein the disk plate is provided with multiple distributors; the distributors are provided with cylindrical bubble caps; the centers of the tops of the bubble caps are provided with round holes, the bottoms of the side surfaces of the bubble caps are provided with tooth seams; the bubble caps are internally provided with central pipes coaxial with the bubble caps; bubble cap supports are welded at the tops of the central pipes, bubble cap auxiliary positioning plates are welded at the middles of the central pipes and the bottoms of the central pipes are covered by clamp plates; the tops of the clamp plates are provided with fixed pull rods, the side surfaces of the clamp plates are provided with bumps, and the bottoms of the clamp plates are provided with stream breakers; the bubble caps and the central pipes are connected by virtue of the clamp plates and the fixed pull rods and fixed to the disk plate. The gas-liquid distribution disk has the characteristics of reliable structure, reasonable design and uniform material distribution; by use of spiral tooth seams, the gas carrying capability can be improved, and a rotation effect can be generated by a medium; the structure of the distributor is simplified by virtue of the design of the fixed pull rods, and the central pipes and the bubble caps are fixed to the disk plate by only locking fixed nuts at the tops of the pull rods.

Description

technical field [0001] The invention relates to a hydrogenation reactor, in particular to a gas-liquid distribution plate for the hydrogenation reactor. Background technique [0002] In recent years, due to the increasing demand for high-quality distillate oil in the domestic market, increasingly stringent environmental protection requirements, and the heavy and inferior quality of crude oil, refineries urgently need to expand the production capacity of hydrogenation units, and hydrocracking is currently the only one that can A process for producing high-quality light distillates from low-quality distillates. The reactor is the core equipment of the hydrocracking process. Due to the exothermic heat of gas, liquid and solid in the hydrogenation reaction, in order to make the reaction feed fully, uniformly and effectively contact the catalyst, there are generally more than two catalyst beds in the reactor, and the top of each bed is A gas-liquid distribution plate is provide...
