Gas-liquid distribution device

Abstract

The invention discloses a gas-liquid distribution device, which comprises an umbrella cap, an overflow pipe and a distribution disc which are arranged from top to bottom; the umbrella cap is conical and umbrella-shaped and is arranged at the upper end of the overflow pipe; the overflow pipe is a circular pipe with two open ends; the lower end is fixed on a mounting hole of the distribution plate;a gas-phase channel is arranged at the joint of the overflow pipe and the umbrella cap, one or two or more layers of overflow holes are evenly formed in the pipe wall in the circumferential directionto serve as liquid-phase channels, a liquid collecting disc is arranged below each layer of overflow holes in the overflow pipe, the liquid collecting discs are concave flat-bottom discs and fixedly connected with the pipe wall of the overflow pipe through convex concave edges, and distribution holes are evenly distributed in the bottoms of the liquid collecting discs for gas-liquid two-phase passing. According to the invention, gas-liquid two-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 device. 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. The...
