[0043] Working principle: When the extraction tower body 1 is used to extract aromatic hydrocarbons in heavy oil, the external raw material heavy oil is first introduced into the interior of the extraction tower body 1 through the feed pipe 6. After the introduction is completed, the first control valve on the feed pipe 6 is closed, and the first motor 5 is started. The first motor 5 drives the first transmission shaft 9 to rotate, and the first transmission shaft 9 drives multiple turntables 14 to rotate.
