Gas-liquid distribution equipment

Abstract

The invention discloses gas-liquid distribution equipment. The gas-liquid distribution equipment comprises a blocking cap, a mixing pipe and a distribution disc which are arranged from top to bottom;the blocking cap is in a circular flat plate or conical umbrella shape and is arranged at the upper end of the mixing pipe, and a gap between the blocking cap and the upper end of the mixing pipe serves as a gas-phase channel; the mixing pipe is an inverted conical pipe with two open ends, wherein the upper end is a large end serving as a mixing pipe inlet, and the lower end is a small end servingas a mixing pipe outlet; the lower end of the mixing pipe is fixed on a mounting hole of the distribution disc; overflow holes are formed in the pipe wall of the mixing pipe as liquid phase channels;the inner wall of the mixing pipe is provided with a rotary guide vane; the tail end of the rotary guide vane and the inner wall of the mixing pipe in front of an outlet of the mixing pipe are provided with one or two or more layers of liquid collecting discs; the liquid collecting discs are concave flat-bottom discs and are fixedly connected with the wall of the mixing pipe through convex concave edges; and distribution holes are uniformly distributed in the bottoms of the liquid collecting discs to allow a gas phase and a liquid phase to pass through. According to the invention, gas-liquidtwo-phase contact can be enhanced, the gas-liquid two-phase atomization effect is promoted, and the wall flow phenomenon in the overflow pipe is reduced.

Description

technical field [0001] The invention belongs to the field of petroleum refining and chemical equipment, and relates to a reactor internal component, in particular to a gas-liquid distribution equipment. Background technique [0002] In recent years, with the gradual upgrading of petrochemical product quality standards and increasingly stringent environmental protection regulations, hydrogenation technology has played an increasingly important role in the oil refining industry. In order to improve economic efficiency and meet the requirements of environmental protection, oil refining enterprises have rapidly expanded the hydrotreating capacity of various oil products. [0003] The key core equipment for hydroprocessing is the hydrogenation reactor. Inside the hydrogenation reactor, a mixture of a certain proportion of hydrogen (gas phase) and raw oil (liquid phase) is used at a certain temperature and pressure to complete various hydrogenation processes. hydrogen reaction. ...
