Abstract

The invention discloses a spiral-flow type electric dehydrator for crude oil. The spiral-flow type electric dehydrator is characterized by comprising an air collection chamber, an oil collection chamber, an oil inlet pipe, a cylindrical section, plate electrodes, an overflow pipe, a conical section, a dehydrated water discharging pipe, an exhaust pipe, a dehydrated oil discharging pipe, wherein the plate electrodes are arranged in a spiral mode along the periphery of the overflow pipe, and every two adjacent plate electrodes are installed in a staggered mode. According to the spiral-flow type electric dehydrator for crude oil, the hydraulic cyclone technique is adopted, crude oil dehydrating efficiency is improved, the size of the dehydrator is reduced, and crude oil dehydrating time is shortened.

Description

Technical field [0001] The invention relates to a crude oil emulsion dehydration method, in particular to a crude oil dehydration device combining cyclone separation and electric dehydration technology. Background technique [0002] Crude oil extracted from oil fields contains a lot of water. In order to meet the water content requirements of exported crude oil, the crude oil produced in oil fields needs to be dehydrated. The free water in crude oil is easily separated from the oil by sedimentation; while the emulsified water in it forms a water-in-oil emulsion with oil, it is difficult to separate by sedimentation, and special dehydration measures must be adopted. The dehydration of crude oil emulsion usually adopts electric dehydrator. [0003] At present, the crude oil electric dehydrator consists of a tank body and electrode plates suspended inside the tank body. The electrode plate generates a high-voltage electric field, and the water droplets in the crude oil emulsi...
