Oil pipeline heating device

Abstract

The invention relates to the technical field of oil heating devices and provides an oil pipeline heating device. The oil pipeline heating device is high in thermal energy utilizing rate and comprises a metal inner tube (1), a thermal insulation layer (2), a wire wrapping layer (4) and an outer insulating layer (5). A socket (6) capable of leading a wrapping wire of the wire wrapping layer (4) out is arranged on the outer insulating layer, a protrusion (3) is arranged on the thermal insulation layer (2), the protrusion (3) is in contact with the metal inner tube (1), and the thermal insulation layer (2) can form a cavity with the metal inner tube (1) through the protrusion (1) on the thermal insulation layer (2).

Description

technical field [0001] The invention relates to the technical field of petroleum heating devices, and provides an oil pipeline heating device. Background technique [0002] In the process of oil extraction, due to the high wax content of oil and the high oil concentration, it often causes difficulties in oil transportation in oil pipelines. Especially in cold seasons, it is necessary to heat oil pipelines to solve the problem of difficult oil transportation. The existing Petroleum pipeline heating devices mostly use steam or water heating. Regardless of steam heating or circulating water heating, the energy loss is relatively large, and there is an energy loss of more than 50%. In order to improve energy utilization, the existing technology uses electric heating. To heat oil pipelines, the electric heating method has a fast heating response and high energy utilization rate. However, most of the existing electric heating methods use metal oil pipelines to be wound with multi-...

[0002] In the process of oil extraction, due to the high wax content of oil and the high oil concentration, it often causes difficulties in oil transportation in oil pipelines. Especially in cold seasons, it is necessary to heat oil pipelines to solve the problem of difficult oil transportation. The existing Petroleum pipeline heating devices mostly use steam or water heating. Regardless of steam heating or circulating water heating, the energy loss is relatively large, and there is an energy loss of more than 50%. In order to improve energy utilization, the existing technology uses electric heating. To heat oil pipelines, the electric heating method has a fast heating response and high energy utilization rate. However, most of the existing electric heating methods use metal oil pipelines to be wound with multi-turn induction coils, and the metal oil pipelines are heated by electromagnetic induction. However, this kind of heating The way metal oil pipelines are exposed to the air, there is a certain amount of heat loss, which also causes a certain amount of energy waste

And the heated metal oil pipeline is exposed to easily burn the staff
