The invention relates to a
crude oil dehydrating device
combing an
electric field and a
centrifugal field, which consists of a shell, an
electric field and
centrifugal field integral structure, a motor, a
pulley, a triangle
leather belt, a dehydrating power supply device, an
oil tank and a
sewage tank. A
centrifugal field structure consists of a hollow shaft, a liquid inlet
pipe, a water outlet
pipe, an oil outlet
pipe, a sealed taper centrifugal cavity, an oil collector, a liquid
distributor, a water collector, and sealing joints of the water outlet pipe, the oil outlet pipe and the liquid inlet pipe, wherein the hollow shaft is arranged in the vertical center of the shell; the liquid inlet pipe, the water outlet pipe and the oil outlet pipe are arranged in the hollow shaft; the sealed taper centrifugal cavity is arranged in the middle of the hollow shaft; the oil collector is arranged on the upper part in the hollow shaft; the liquid
distributor is arranged in the middle of the hollow shaft; the water collector is arranged on the lower part of the hollow shaft; and the sealing joints are arranged on the upper part of the hollow shaft and do not rotate. An
electric field structure consists of a disk-shaped
electrode plate, the other disk-shaped
electrode plate, moving electrodes and fixed electrodes, wherein the disk-shaped
electrode plate is arranged between the oil collector and the liquid
distributor; the other disk-shaped electrode plate is arranged on the centrifugal cavity and staggered with the electrode plate of the hollow shaft; the moving electrodes are arranged at both ends of the hollow shaft; and the fixed electrodes are arranged at the upper end and the lower end of the shell and correspondingly and movably contact the moving electrodes. The upper fixed electrode and the lower fixed electrode are connected with the dehydrating power supply device; and a motor
pulley is connected with the
pulley on the lower part of the hollow shaft through the.
