Embodiment Construction

[0022] Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but should not be used to limit the scope of the present invention.

[0023] Such as Figure 1-3 As shown, the waxy crude oil transportation pipeline in this embodiment includes: a metal pipeline 1 and a magnetic impeller 2 disposed inside the metal pipeline 1 .

[0024] The metal pipe 1 in this embodiment is preferably a steel pipe. Of course, other occasions can also use metal pipes of other materials, as long as they can generate induced eddy currents under the action of the alternating magnetic field of the magnetic impeller 2 .

[0025] The magnetic impeller 2 is made of magnetic materials such as magnets, and its blades are distributed at intervals between N and S poles (such as figure 1 shown in ), that is, the polarity of adjacent blades is opposite; the b...

Abstract

The invention relates to the technical field of oil delivery, and particularly discloses a wax-bearing crude conveying pipeline. The wax-bearing crude conveying pipeline comprises a metal pipeline and a magnetic impeller arranged in the metal pipeline. The magnetic impeller can freely rotate around the axis of the metal pipeline. Blades of the magnetic impeller are distributed in an N pole and S pole alternate mode. According to the wax-bearing crude conveying pipeline, the magnetic impeller is arranged in the metal pipeline, crude oil inside the metal pipeline flows to push the magnetic impeller to rotate at a high speed, the magnetic field of the pipe wall of the metal pipeline is periodically changed through the magnetic impeller, the pipe wall of the metal pipeline generates induction eddy current under the effect of the alternating magnetic field of the magnetic impeller so as to generate heat, and therefore the crude oil in the metal pipeline can be heated, the pressure energy of the crude oil is partly converted into the heat energy of the pipe wall according to the electromagnetic induction principle, and the whole-line uniform heating or whole-line constant-temperature conveying can be conducted on the wax-bearing crude oil in the metal pipeline.

Description

technical field [0001] The invention relates to the technical field of petroleum transportation, in particular to a heating-free waxy crude oil transportation pipeline. Background technique [0002] With the increasing consumption of petroleum resources and the continuous improvement of oil extraction technology, a large amount of waxy crude oil has been exploited and utilized internationally. The crude oil produced in my country is famous for its high wax content, high viscosity and high freezing point. [0003] Waxy crude oil is often transported through pipelines by means of furnace heating. In the upstream of the pipeline, the temperature of the crude oil is high, which results in a large amount of heat loss due to heat exchange with the environment. In the middle and downstream of the pipeline, due to the sharp drop in the temperature of the oil product, solid wax crystals are continuously precipitated and deposited on the pipe wall, so it is necessary to periodically ...
