Electromagnetic heating heavy oil conveying pipe integrating electromagnetic heating and oil conveying and using method of electromagnetic heating heavy oil conveying pipe

Abstract

The invention provides an electromagnetic heating heavy oil conveying pipe integrating electromagnetic heating and oil conveying and a using method of the electromagnetic heating heavy oil conveying pipe. The electromagnetic heating heavy oil conveying pipe comprises a steel inner pipe, wherein a steel tubular shell sleeves outside the steel inner pipe, a high-temperature-resistant waterproof insulating electric coil is wound around the outer wall of the steel inner pipe, and the top end of the steel inner pipe extends upwards and is fixedly provided with a first flange; a second flange is fixedly installed at the top end of the steel tubular shell, and the bottom of the steel inner pipe and the bottom of the steel tubular shell are sealed through sealing rubber mats and fixed into a wholethrough bolts; and the wiring end of the high-temperature-resistant waterproof insulating electric coil is connected with an electromagnetic generator. According to the electromagnetic heating heavyoil conveying pipe, a traditional heating mode is changed, the electromagnetic heating pipe is matched, and secondary heating is conducted during oil pumping of softened heavy oil, so that the operation efficiency of the heavy oil recycling and heating link is improved. According to the electromagnetic heating heavy oil conveying pipe, the size is small, the weight is light, the underwater installation operation of divers is facilitated, the electromagnetic heating heavy oil conveying pipe is convenient to carry by the divers in cabins, and the underwater mounting and operating efficiency is improved compared with that of the traditional steam heating mode.

Description

technical field [0001] The invention relates to the technical field of shipwreck salvage engineering, in particular to an electromagnetically heated heavy oil delivery pipe integrating electromagnetic heating and oil delivery. Background technique [0002] The principle of electromagnetic induction heating is that the alternating current generated by the induction heating power supply generates an alternating magnetic field through an inductor (that is, a coil), and a magnetically permeable object is placed in it to cut the alternating magnetic force line, thereby generating an alternating current (that is, an eddy current) inside the object. , The eddy current makes the atoms inside the object move at high speed and irregularly, and the atoms collide and rub against each other to generate heat energy, thus heating the object. It is a heating method that converts electrical energy into magnetic energy, so that the heated steel body induces magnetic energy and generates heat....

AI Technical Summary

Problems solved by technology

Although the existing technology can heat and soften non-fluid heavy oil in special environments, the steam boiler has a large volume, heavy weight, and high maintenance costs. The heating pipeline is limited by the water depth, and the heat loss is large. Difficult tube operation, low heating efficiency, etc.
