Abstract:
Provided is an electric desalting and dehydration apparatus, including an oil inlet distributor of an upper electric field, wherein the oil inlet distributor includes an oil inlet distributing pipe and an oil inlet branch pipe. The oil inlet distributing pipe is arranged in a water tray of an electric desalter, and below a ground electrode of the electric desalter. The oil inlet branch pipe is connected to the oil inlet distributing pipe to supply crude oil into the oil inlet distributing pipe. The oil inlet distributing pipe is provided with oil outlets on both sides thereof in a horizontal direction. The distributor can uniformly distribute crude oil in a water tray, thus all of the crude oil is kept in an electric field for an equal time.

Claim (Index 3):
The electric desalting and dehydration apparatus according to  claim 1 , further comprising a bottom automatic sand flushing device, wherein the bottom automatic sand flushing device is provided at the bottom of the electric desalter, and comprises an automatic sand removal plate, a backwash pipe group, a backwash inlet pipe, an on/off valve, sprayers, an ultrasonic sludge interface instrument, and an automatic control system; the automatic sand removal plate is fixedly provided at the bottom of an inner wall of the electric desalter; the backwash pipe group is provided inside the electric desalter and above the automatic sand removal plate, and comprises several backwash pipes; the sprayers are evenly provided on each of the backwash pipes; the backwash inlet pipe is connected to the backwash pipes; the on/off valve is provided in the backwash inlet pipe; the ultrasonic sludge interface instrument is provided at the bottom of the electric desalter, and is used for detecting the thickness of silt that settles in the electric desalter; the ultrasonic sludge interface instrument and the on/off valve are both in signal connection with the automatic control system; and when the ultrasonic sludge interface instrument detects that the thickness of the silt that settles at the bottom of the electric desalter exceeds a threshold, the automatic control system switches on the on/off valve, to flush the silt at the bottom of the electric desalter.
