The invention discloses a low-voltage transparent electrothermal film which comprises a transparent base material, a transparent conductive layer and electrodes. The transparent conductive layer is formed on at least one side of the transparent base material; the electrodes are formed by bus bars and a plurality of inner electrodes, wherein the inner electrodes extend oppositely from the bus bars to form interdigital electrodes; and the electrodes are arranged on the transparent conductive layer and are in electrical contact with the transparent conductive layer. Through the arrangement of the bus bars and the inner electrodes, distance between two electrodes is reduced and resistance of the transparent conductive layer between the two electrodes is reduced, so that low-voltage power supply can be used, and the voltage of a daily lithium battery can be used normally, and a temperature of 90-180 DEG C can be reached quickly by heating. The two surfaces of graphene can be provided with two sets of electrodes respectively, and the inner electrodes of the two sets of electrodes are staggered for a certain distance, so that heating uniformity can be further ensured. The heating temperature is improved under the same low voltage.

The high-efficiency electric dehydrator is characterized by comprising an electric dehydrator shell (1), and an oil inlet pipe (2), a water outlet pipe (3) and an oil outlet pipe (6) which are arranged in the electric dehydrator shell (1), wherein the oil inlet pipe (2) and the water outlet pipe (3) are arranged on the lower part of the electric dehydrator shell (1); the oil outlet pipe (6) is arranged on the upper part of the electric dehydrator shell (1); theinlet of the oil inlet pipe (2) extends out of the outer part of the electric dehydrator shell (1) and is connected with a reciprocating piston pump (9); an electrode and a suspension needle grounding electrode (5) are arranged in the electric dehydrator shell (1); the suspension needle grounding electrode (5) vertically penetrates through a runner inside the electrode; and one side on the lowerpart of the electric dehydrator shell (1) is grounded. With the adoption of the structure that the suspension needle grounding electrode vertically penetrates through the runner inside the electrode,the electrode spacing is greatly narrowed, so that the electric field of the same intensity can be generated at a lower voltage, and the coalescence rate of water drops can be effectively improved. Therefore, the dehydration efficiency is improved, and the treatment capacity is increased.
