High-frequency intelligent response electro-desalting complete equipment

Abstract

The invention discloses high-frequency intelligent response electro-desalting complete equipment, which comprises a horizontal electro-desalting tank body, wherein a transformer is arranged on the outer side of the top of the tank body, an outlet oil collecting pipe which is axially parallel to the tank body is arranged on the inner upper part of the tank body; an inlet oil distribution pipe axially parallel to the tank body is arranged on the lower part of the tank body; a suspended netty electrode plate is arranged in the tank body; a transformer explosion-proof control system is arranged on the side face of the outside of the tank body; the explosion-proof control system can monitor a current at one time of operation and at the same time intelligently regulate an output voltage according to current; and a frequency regulating button is arranged on the transformer explosion-proof control system.

Description

technical field [0001] The invention relates to a complete set of electric desalination equipment for crude oil, which belongs to the technical field of electric desalination in the crude oil pretreatment process, and in particular to a complete set of electric desalination equipment with adjustable input frequency and automatic response adjustment of primary input voltage according to secondary current changes. Background technique [0002] In recent years, the instability of the crude oil supply market and the irregular fluctuation of crude oil prices have greatly increased the cost of crude oil refining. In order to adapt to changes in the crude oil market and reduce crude oil processing costs, some low-quality crude oil is often purchased or blended, and even some refineries have completed the transformation from processing light high-quality crude oil to processing heavy low-quality crude oil. Although these low-quality crude oils reduce the purchase cost, they make the...

AI Technical Summary

Problems solved by technology

However, there are three problems in this electric desalination dehydrator. One is that the high-voltage input is only pulsed, which cannot achieve a good demulsification effect; the other is that the first electrode is grounded, and the second electrode is charged, and the charged electrode pair is grounded during work. The electrodes are directly discharged to form a circuit and form a high-voltage electric field, and the power consumption is relatively high; the third is to ensure a horizontal oil flow, the electrodes are a grid structure, which is relatively sparse, and the formed high-voltage electric field is not dense
