Zusammenfassung:The invention discloses a device for improving comprehensive utilization efficiency of waste heat of carbon black oil, which comprises a fraction tower, a carbon black oil tank, a carbon black oil primary cooling water tank and a tar tank, the carbon black oil primary cooling water tank is connected with the fraction tower and is used for primarily cooling the carbon black oil produced from the fraction tower, and the device also comprises a heat exchanger, the heat exchanger is connected with the carbon black oil primary cooling water tank, the carbon black oil tank and the tar tank, the carbon black oil which is primarily cooled by the carbon black oil primary cooling water tank and still has higher temperature flows into the heat exchanger and exchanges heat with low-temperature tar flowing into the heat exchanger in the tar tank, and the carbon black oil after heat exchange flows into the carbon black oil tank. According to the invention, the temperature of the raw material tar is increased by using the w
