A baffle disc type shock reduction and equalization disc

Abstract

The invention discloses a baffle disc type impact-reducing flow equalizing disc which comprises a tower disc and a plurality of downcormer distributors vertically arranged on the tower disc, wherein each of the chimney distributors comprises a downcomer and an impact-reducing plate fixedly connected to the upper end of the downcomer; the impact-reducing plate comprises a bottom plate and a plurality of parallelly arranged baffle plates fixed to the upper surface of the bottom plate; the upper part of the downcomer is an oblique line cut and the lower end is opened; the plurality of baffle plates are parallel to the axis of a reactor or are located on the same plane with the axis of the reactor. The impact-reducing flow equalizing disc is a member which is newly arranged in a hydrogenationreactor, is arranged in a head idle space of the reactor or at the upper end of a barrel of the reactor, so that powerful impact of a fluid entering the reactor formed by residual kinetic energy can be subducted, and a wave-pushing phenomenon of an inclined flow line to a liquid layer of a distributing disc when the fluid enters at the center point is eliminated. The impact-reducing flow equalizing disc is suitable for all hydrogenation reactors, in particular hydrogenation reactors which are relatively large in scale, and can achieve initial distribution of materials.

Description

technical field [0001] The invention relates to a baffle plate-type shock-reducing and flow-distributing plate, which belongs to the field of chemical equipment. Background technique [0002] In recent years, with the rapid development of my country's national economy and the enhancement of environmental protection awareness, the quality and environmental protection requirements of petrochemical products are getting higher and higher. In order to meet the needs of processing sour crude oil, meet the ever-increasing demand for chemical raw materials, and improve product quality, the importance and role of hydrogenation technology in the oil refining industry is increasing. In the hydrogenation unit, the hydrogenation reactor, which is the key equipment, completes the refining and cracking reactions of the feedstock oil mixed with hydrogen in a certain proportion by the action of the hydrogenation catalyst. Whether the hydrogenation reaction in the hydrogenation reactor can o...

Problems solved by technology

The bubble cap distributor based on the suction principle is easily covered or partially covered, resulting in uneven material distribution, and when the inlet liquid is unevenly distributed, it will seriously affect the effect of the top distributor of the hydrogenation reactor

[0021] In view of the technical problems that the traditional gas-liquid distributor has weak anti-tray tilting ability and the influence of the uneven depth of the liquid layer on the distribution plate, it is necessary to develop a gas-liquid distributor with the function of reducing the impact and equalizing the flow, with small volume, good distribution effect and low installation accuracy. The new internal component technology is used to reduce the strong impact force formed by the residual kinetic energy of the fluid entering the reactor, and is used to eliminate the "wave pushing" phenomenon of the liquid in the inclined flow state on the liquid layer on the distribution plate, so as to realize the uniform distribution of the fluid
