Sleeve type flushing reduction flow equalization disc

Abstract

The invention discloses a sleeve type flushing reduction flow equalization disc which comprises a tower disc and a plurality of chimney distributors, wherein the chimney distributors are arranged on the tower disc; the chimney distributors comprise downcomers and flushing reduction cylinders arranged at the upper ends of the downcomers; both the flushing cylinders and the downcomers are of cylindrical structures of which two ends are opened; the flushing reduction cylinders and the downcomers are arranged up and down; and the diameters of the flushing reduction cylinders are greater than thoseof the downcomers. The flushing reduction flow equalization disc disclosed by the invention is a new internal component and is arranged inside an idle space inside an upper sealing head of a hydrogenation reactor or at the upper end of the cylinder of the hydrogenation reactor. By adopting the flushing reduction flow equalization disc disclosed by the invention, intense impact of residual kineticenergy of a fluid entering the reactor can be reduced, and the phenomenon of 'push waves'caused by inclined flowing lines to the liquid layer of a distribution disc when the fluid enters a central point can be eliminated. The sleeve type flushing reduction flow equalization disc disclosed by the invention is applicable to all hydrogenation reactors and particularly applicable to hydrogenation reactors which are relatively large in liquid-gas ratio and relatively large in scale.

Description

technical field [0001] The invention relates to a sleeve type shock reducing and equalizing plate, which belongs to the field of chemical equipment. The sleeve-type shock-reducing flow equalizer of the present invention is a new internal component for the reactor. The sleeve-type impact reducing and equalizing plate of the present invention is suitable for various hydrogenation reactors, especially suitable for large-scale hydrogenation reactors with relatively large liquid and gas. 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 indus...

AI Technical Summary

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
