The utility model relates to the technical field of electric dehydrators and discloses a super-heavy oil high-temperature crude oil electric dehydrator. The super-heavy oil high-temperature crude oil electric dehydrator comprises a tank body, a feeding pipe, a material inlet and liquid distribution pipe manifold, a water outlet pipe, a vertical hanging electrode group, an oil collection device, an oil baffle plate, an emulsified oil outlet device and a sand washing device, wherein a partition plate is fixedly mounted in the left part of the tank body, and an inner cavity of the tank body is divided into a buffer cavity on the left side and an electric dehydration cavity on the right side; the feeding pipe is fixedly mounted on the tank body at the upper part of the buffer cavity; at least one material inlet and liquid distribution pipe manifold communicated with the buffer cavity is fixedly mounted at the lower part of the electric dehydration cavity. The super-heavy oil high-temperature crude oil electric dehydrator disclosed by the utility model has the advantages of reasonable and compact structure and convenience in use; preliminary settlement is performed through the buffer cavity, so that the water content in produced liquid is reduced, the stability in operation of the vertical hanging electrode group is ensured, and the oil-water separation effect of the produced liquid is simultaneously improved; simultaneously, the material inlet and liquid distribution pipe manifold can enable the produced liquid entering the electric dehydration cavity to realize uniform liquid distribution and diversion, thereby shortening the settlement time, accelerating the dehydration speed, improving the quality of produced oil and effectively reducing the energy consumption.
