The invention relates to the technical field of carbon black oil production, and discloses carbon black oil, a preparation method of the carbon black oil and a vacuum suction filtration dewaxing device.The preparation method of the carbon black oil comprises the following steps that after furfural extract oil is treated with a butanone solvent, suction filtration dewaxing treatment is conducted, and dewaxed furfural extract oil is obtained; the preparation method comprises the following steps: modifying petroleum asphalt by using terephthalyl alcohol, a polymer, dewaxed furfural extract oil, p-toluenesulfonic acid and sulfur powder to obtain a modified petroleum asphalt mixture; and mixing the modified petroleum asphalt mixture with anthracene oil to prepare the carbon black oil. The modified petroleum asphalt mixture prepared by the invention has low carcinogenicity, high-temperature stability and low-temperature flexibility, so that the carbon black oil prepared from the modified petroleum asphalt mixture a
