Description

Technical Field

[0001] The utility model relates to the technical field of oil refining, in particular to an inlet distributor for refining equipment. Background Technique

[0002] As is well known, the crude oil extracted from the ground needs to be refined to become various usable oil components. Among them, oil refining is a process of distilling crude oil or other oils without changing the molecular structure. Since, in the process of petroleum refining, crude oil must go through a series of process steps to obtain various useful petroleum products. Generally speaking, it refers to petroleum refining, that is, cracking crude oil and the like into fuels such as kerosene, gasoline, diesel, and heavy oil that meet the requirements of internal combustion engines, and producing chemical raw materials such as olefins and aromatics. Nowadays, general refineries are oil-chemical integrated refineries. During the process of crude oil entering the refining equipment for refining, various distributors need to be added to achieve sufficient cracking and decomposition of crude oil inside the refining equipment. However, the existing inlet distributors cannot solve this problem well.

[0003] For example, an inlet distributor for refining equipment (Publication No.: CN207646138U), the device includes an inlet distributor cylinder body and a bottom plate fixed at the lower end of the inlet distributor cylinder body. Among them, since long strip-shaped distribution holes are evenly arranged in the circumferential direction of the inlet distributor cylinder body, and circular through holes are evenly arranged on the bottom plate, the catalyst enters the refining equipment through the inlet distributor of this device. Through the long strip-shaped distribution holes and the circular through holes, the catalyst can be fully dispersed and diffused during the process of entering the refining equipment, improving the full contact between the crude oil and the catalyst, ensuring the full cracking and decomposition of the crude oil inside the refining equipment, and at the same time, it can also improve the effective utilization rate of the catalyst, reduce the refining cost of the crude oil, and improve the refining efficiency of the crude oil.

[0004] When this device is in use, it can only passively improve the decomposition and diffusion of the catalyst, so the efficiency of catalyst decomposition and diffusion is not high enough. Therefore, we need to propose an inlet distributor for refining equipment. Content of the Utility Model
