A quick distillation device for petroleum crude oil

Abstract

The invention relates to the field of chemical equipment, and in particular, relates to a rapid distillation device for petroleum crude oil, wherein the rapid distillation device comprises an outer shell, a preheating structure, a waste heat utilization structure, a pressurization structure, a drain valve, a liquification structure, a storage structure, a separation plate and a vaporization structure. The interior of the outer shell is provided with the vaporization structure for vaporizing the petroleum crude oil and the storage structure for storing liquefied products; the top end of the storage structure is provided with the liquification structure for liquefying petroleum vaporized products; the side wall of the outer shell is provided with the pressurization structure connected with the storage structure; the pressurization structure is connected with the liquification structure; the top end of the outer shell is provided with the waste heat utilization structure, and the liquification structure is connected with the waste heat utilization structure; the interior of the waste heat utilization structure is provided with the preheating structure for preheating the petroleum crude oil. The liquification structure is connected with the waste heat utilization structure, and the waste heat utilization structure cooperates with the use of the preheating structure to facilitate the replacement of the liquefied heat into the heat of the petroleum crude oil, so the vaporization efficiency and quality of the petroleum crude oil are higher.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a quick distillation device for petroleum crude oil. Background technique [0002] Distillation is a thermodynamic separation process. It utilizes the different boiling points of the components in the mixed liquid or liquid-solid system to evaporate the low-boiling components and then condense them to separate the entire components. There are two types of evaporation and condensation. The combination of unit operations, compared with other separation methods, such as extraction, adsorption, etc., has the advantage that it does not need to use other solvents other than system components, so as to ensure that no new impurities will be introduced. Distillation devices are widely used in petroleum In the separation and extraction of crude oil. [0003] However, the traditional petroleum crude oil fast distillation device and petroleum crude oil have small heating area, poor vaporiz...
