Abstract

The invention provides a petroleum distillation device for petroleum refining, which comprises a distillation retort and a sealing device, one side of the distillation retort is provided with a gas pipe and a feeding pipeline at an interval, the lower part of the distillation retort is provided with a discharge port, the upper part of the distillation retort is provided with a pressure relief port, and the pressure relief port is provided with the sealing device for exhausting. The distillation retort can be sealed into a decompression retort or a normal-pressure retort through the sealing device according to needs, so the function of flexibly switching the heavy distillation retort in the actual production process is realized, the distillation modes can be freely switched in the normal-pressure distillation process and the reduced-pressure distillation process, and the distillation mechanism can be adjusted at any time for distillation according to needs in the petroleum distillation process, so that the purpose of improving the distillation efficiency is achieved.

Description

technical field [0001] The invention relates to the technical field of petroleum distillation, in particular to a petroleum distillation device for petroleum refining. Background technique [0002] Distillation is the first process of crude oil processing. Through distillation, crude oil can be divided into various fractions such as gasoline, kerosene, diesel oil, lubricating oil, and raw materials for secondary processing. Crude oil distillation units occupy an important position in refining and chemical enterprises, and are known as the "leader" of refining and chemical enterprises. Distillation plays a very important role in petroleum refining and is usually an important indicator to measure the production capacity of a refinery. [0003] Crude oil distillation usually includes two parts: atmospheric distillation and vacuum distillation. The so-called atmospheric distillation refers to the distillation of crude oil at atmospheric pressure or slightly higher than atmosph...
