Graphene heater for oil tank of oil field

Abstract

Disclosed is a graphene heater for an oil tank of an oil field. A heating layer of the heater is a graphene layer (); a high-temperature-resistant insulating layer (), an intermediate layer composed of the graphene layer () and electrode layers (), and a high-temperature-resistant insulating layer () are tightly attached together in sequence and then attached to an inner wall of a housing (); the housing () is columnar; one end of the housing () mounted in the oil tank is closed; the other end of the housing is fixed on a surface of the oil tank by means of a flange plate (); the flange plate () of the housing () is partially connected to a junction box (); and when the electrode layers () at two ends of the graphene layer () are powered on, under the action of an electric field, heat energy generated by severe friction and impact between carbon atoms of graphene is radiated by means of far infrared ray with a wavelength of 5 to 14 microns, so that heat is effectively provided, so as to realize heating, heat preservation and freezing prevention of the oil tank of the oil field.
