Device for desalting polluted crude oil

Abstract

The utility model relates to the field of polluted crude oil treatment, in particular to a device for desalting polluted crude oil, which comprises a first prying body, a second prying body, a first oil pool conveying system, a polluted crude oil pretreatment system, a polluted crude oil electric desalting system and a control system. According to the utility model, the electromagnetic induction heating device is adopted to heat the polluted crude oil, and the electromagnetic coil of the heating element is not directly contacted with the polluted crude oil to be heated, so that the corrosion of high-concentration chloride ions in the polluted crude oil to the heating element is fundamentally avoided; the electromagnetic induction heating device is adopted to heat the polluted crude oil, stepless adjustment of heating power can be achieved by changing the current magnitude and frequency of the electromagnetic coil, and the stability of the follow-up electro-desalting treatment process is improved. Meanwhile, a heat exchange pipe is arranged at the inlet end of the first crude oil pump, waste heat utilization of waste process water can be achieved, and the problems that in cold weather, crude oil viscosity is greatly increased, the crude oil pump flow is reduced, and the pump damage frequency is increased are solved.
