Problems solved by technology

[0003] During the electrolytic desalination of crude oil, due to the need to keep stirring the crude oil, when the demulsifier is added, the demulsifier will be broken up by the high-speed rotating stirring rod, and part of the broken up demulsifier will easily fly to and adhere to the On the electrode plate, the electrode plate is corroded by the demulsifier, which affects the service life of the electrode plate. In addition, due to the large space in the electrolysis chamber, the proportion of the demulsifier and the water sprayed into the crude oil is very small. The distribution of emulsion and clear water is scattered, and they will not be able to effectively cooperate with each other to dilute impurities, so that the desalination efficiency of crude oil cannot be further improved
[0004] After the electrolytic desalination of crude oil is completed, after standing for a period of time, some impurities will enter the wastewater layer from the crude oil layer and deposit on the bottom of the water, and then open the drain valve to allow the wastewater to drive the impurities to flow out from the bilge and collect them. The remaining crude oil is collected. However, when the waste water is drained, in order to ensure that the suspended impurities in the clear water can be completely removed, the draining time of the clear water will be extended, especially when the clear water is discharged to the end, due to liquid flow. The vortex will cause a large amount of crude oil to be removed from the middle along with the wastewater, so that the discharged wastewater contains a large amount of crude oil, which will make the cleaning steps of the wastewater in the later stage heavy.

Abstract

The invention relates to the technical field of oil treatment, in particular to crude oil treatment equipment for oil exploitation environment protection. The technical problems to be solved are that the demulsifier and clear water are distributed in a scattered mode, the desalting work efficiency of crude oil is affected, and the content of crude oil in waste water discharged in the later period is large due to the fact that impurities are distributed in a scattered mode. According to the technical scheme, the crude oil treatment equipment for oil exploitation environment protection comprises a stirring assembly, a milking and diluting assembly and the like; and a demulsifier nozzle is fixedly connected to a top plate of the electrolysis cabin. In the technical scheme provided by the invention, impurities in crude oil and clear water are intensively demulsified, and clear water is timely supplemented to dilute the impurities, so that the working efficiency of mutual cooperation of the demulsifier and the clear water is greatly improved, and most impurities are concentrated in the central area of the bottom of a cabin; and a large amount of crude oil can be prevented from being mixed in wastewater in later layered drainage work.

Description

technical field [0001] The invention relates to the technical field of petroleum processing, in particular to crude oil processing equipment for environmental protection of petroleum exploitation. Background technique [0002] The crude oil obtained after oil extraction needs to be desalted and dehydrated first, and then dewaxed and reformed to facilitate long-distance transportation. The desalted and dehydrated crude oil is usually treated by electrolysis, which means that the crude oil is introduced into the electrolysis chamber and a demulsifier is added. The desalted crude oil and water are separated and collected separately after electrolysis. [0003] During the electrolytic desalination of crude oil, due to the need to keep stirring the crude oil, when the demulsifier is added, the demulsifier will be broken up by the high-speed rotating stirring rod, and part of the broken up demulsifier will easily fly to and adhere to the On the electrode plate, the electrode plat...
