Gas-liquid distributor having hanging structure

Abstract

The invention relates to a gas-liquid distributor having a hanging structure. The distributor is composed of an outer tube and an inner tube, the outer tube is connected with the inner tube through a support plate, the top of the outer tube is sealed through a cover plate, the wall of the outer tube is provided with a tunnel as a gas-liquid fluid inlet, the outer tube is a support tube and is arranged on the tower disc of the distributor, the inner tube has a hanging structure, the lower portion of the inner tube has a distance of 30-50mm to the tower disc, and the inner tube is arranged on the outer tube through the support plate; and the support plate is an annular plate between the inner tube and the outer tube and fixes the inner tube to make the inner tube have the hanging structure and prevent a flow from downward flowing along an annular gap between the inner tube and the outer tube, and the outlet end of the outer tube has a flaring structure, has a diameter 1.2 times the diameter of a straight tube segment and has a height 0.2 times the diameter of the straight tube segment. The above structure reserves the advantages of suction flow, effectively solves a non-uniform liquid distribution problem caused by the inclination of a tower plate, and allows the pressure drop of the distributor to be 2-3kPa, so the gas-liquid distributor is a low-pressure-drop distributor.

Description

technical field [0001] The invention relates to a gas-liquid distributor with a suspended structure which uniformly disperses the inlet liquid in the space below it under the condition of gas-liquid two-phase flow. technical background [0002] The gas-liquid distributor is an important internal component in the hydrogenation reactor. The gas-liquid two-phase passes through the distributor and is evenly distributed to the catalyst bed. Its performance is mainly measured from the following three aspects: pressure drop, distribution performance and operating elasticity. The distribution performance is measured from two aspects: the liquid distribution spray surface and the peak value of the liquid distribution along the radial direction. The smaller the peak of the distribution, the better the distribution performance of the distributor. [0003] With the continuous research on the principle of the gas-liquid distributor, the pure overflow distributor is no longer used, and t...

Problems solved by technology

[0011] The purpose of the present invention is to provide a distributor structure with a gas-liquid flow mode, which overcomes the shortcomings of the current gas-liquid distributors that the liquid flows along the wall of the distribution pipe in a film shape and the size of the liquid mass in the pipe is too large to cause the liquid to be difficult to disperse.
