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
[0011] Aiming at the technical problems that the traditional gas-liquid distributor has weak anti-tray tilting ability and the uneven depth of the liquid layer on the distribution plate has a great influence, it is necessary to develop a new type of internal component technology with good distribution effect and low installation accuracy requirements for Reduce the strong impact force formed by the residual kinetic energy of the fluid entering the reactor, which is used to eliminate the "wave pushing" phenomenon of the liquid in the inclined flow state on the liquid layer on the distribution plate, and realize the uniform distribution of the fluid

Embodiment 1

[0042] Compared with Comparative Example 1, in Example 1 of the present invention, the ring-plate type shock-reducing flow equalizing plate of the present invention is arranged in the upper head of the hydrogenation reactor, and such as figure 1 The ring-plate type shock-reducing flow divider shown is used in combination with a common ERI type bubble-cap type gas-liquid distributor. The parameters of the ring-plate-type flush-reducing flow-distributor are: the ring-plate-type flush-reducing flow-distributor includes a tray and a distributor, and the distributor is arranged on the tray in the form of concentric circles by 8 layers of flush-reducing ring plates, A drop pipe 2 for collecting and discharging materials is arranged between two adjacent layers of impact-reducing ring plates. The height of the impact-reducing ring plate is 80mm; the lower edge of the impact-reducing ring plate is provided with a semicircular hole as a liquid phase channel, and the total cross-sectiona...

Embodiment 2

[0044] The same as Example 1, the difference is that the conventional ERI gas-liquid distributor in the field in the original hydrogenation reactor is canceled, and only the ring plate type flush reduction and equalizer plate provided in the present invention is retained, and the bed layer is radially The temperature and temperature difference are shown in Table 1.

Abstract

The invention discloses an annular plate type impact reducing and flow equalizing tray and belongs to the field of chemical equipment. The annular plate type impact reducing and flow equalizing tray comprises a column tray and distributors arranged on the column tray, wherein the distributors are arranged on the column tray in a concentric circle form by a plurality of layers of impact reducing annular plates, and multiple dropping pipes for collecting and discharging materials are arranged between every two adjacent impact reducing annular plate. The annular plate type impact reducing and flow equalizing tray has the characteristics of impact reducing and flow equalizing functions, good distribution effect, small size, low installation precision requirement and the like.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a reactor internal component. 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. Whether the hydrogenation reaction can be operated stably, whether the hydrogenation catalyst can fully play its role, and whether the product quality can achieve high quality largely depend on the uniformity of the distribution of gas-liquid materials in the catalyst bed in the hydrogenation reactor. . The uniform distribution of gas and...
