The invention belongs to the technical field of needle coke, and particularly relates to a method and a device for evaluating foamability of raw material oil slurry for needle coke production. The method comprises the following steps: adding 80-120ml of raw material oil slurry into a flask for distillation, sensing pressure through a gas measuring cylinder, measuring the foaming height, and evaluating the foaming performance of the raw material oil slurry; the device comprises a shell, a distillation chamber is arranged in the shell, an electric furnace is arranged at the bottom of the distillation chamber, a flask is arranged on the electric furnace, a thermometer is inserted into the upper end of the flask, a condenser is obliquely arranged on one side of the flask, the lower end of the condenser is connected with a gas measuring cylinder, and a light capture plate is arranged on one side of the gas measuring cylinder. The gas measuring cylinder is transparent, a sliding groove is formed in the side wall of the gas measuring cylinder, a sliding block matched with the sliding groove is arranged in the sliding groove, the lower end of the sliding block is connected with a hydraulic rod, the hydraulic rod is connected with a hydraulic cylinder, and a detection lamp holder is arranged on the sliding block. By distilling the raw material oil slurry, the foaming height of the raw material oil slurry is accurately measured, and then the foaming performance of the oil slurry is evaluated.
Description
technical field [0001] The invention belongs to the technical field of needle coke, and in particular relates to a method and a device for evaluating the foamability of a needle coke production raw material oil slurry. Background technique [0002] Needle coke is a high-quality carbon raw material developed in recent years. According to the source of raw materials, it is divided into coal-based needle coke and oil-based needle coke. The carbon products of needle coke have high crystallinity, low ablation, low The thermal expansion coefficient and other characteristics have a wide range of high-value applications in the fields of industry, medical treatment, aerospace, national defense, and atomic energy. The graphite electrodes made of it have the characteristics of good heat resistance, high mechanical strength, and good oxidation resistance. Economic value extremely high. [0003] The preparation of needle coke is inseparable from raw material oil. The properties of raw m...
