Crude oil anti-corrosion treatment equipment based on electronic control

Abstract

The invention discloses crude oil anti-corrosion treatment equipment based on electronic control. The crude oil anti-corrosion treatment equipment comprises a desalting tank, wherein two high-voltage electric field mechanisms are arranged in the desalting tank; the two high-voltage electric field mechanisms are symmetrical relative to the central line of the desalting tank; a centrifugal mixing device is further arranged between the two high-voltage electric field mechanisms; the central axis of the centrifugal mixing device is overlapped with the central line of the desalting tank; two sewage outlets are formed in the bottom of the desalting tank; the sewage outlets correspond to the high-voltage electric field mechanisms one by one and are located just below the high-voltage electric field mechanisms; each high-voltage electric field mechanism comprises a plurality of positive electrode plates and negative electrode plates; the positive electrode plates and the negative electrode plates are alternately arrayed in parallel along the axial direction of the desalting tank and form a plurality of water removal channels at equal intervals; the water removal channels communicate with the sewage outlets; and the positive electrode plates and the negative electrode plates are further provided with a plurality of water suction holes and the water suction holes are uniformly distributed on the positive electrode plates and the negative electrode plates. By adopting the crude oil anti-corrosion treatment equipment based on the electronic control, the problem that the desalting effect of the single desalting tank is relatively poor is solved.

Description

technical field [0001] The invention relates to the technical field of crude oil treatment, in particular to electronically controlled crude oil anticorrosion treatment equipment. Background technique [0002] Atmospheric distillation and vacuum distillation are commonly referred to as atmospheric and vacuum distillation, and atmospheric and vacuum distillation is basically a physical process. The raw oil is divided into oil products (called fractions) with different boiling point ranges according to the evaporation capacity in the distillation tower. Some of these oils are blended and added with additives before leaving the factory in the form of products, and a considerable part is the raw material for subsequent processing devices. Therefore, , Atmospheric and vacuum distillation is also known as primary processing of crude oil. It includes three processes: crude oil desalination, dehydration, atmospheric distillation, and vacuum distillation. [0003] The crude oil sen...
