Embodiment 1
[0092] The fuel oil is pumped to be mixed with the air provided by the main supply fan and preheated to 850°C by the air preheater, and then combusted in the combustion section to generate a high-temperature combustion airflow of about 1900°C; the raw oil is preheated to a certain temperature by the preheater After that, it is sprayed into the throat section of the reaction furnace, mixed with the high-temperature combustion airflow, and rapidly cracked to produce carbon black flue gas; then, it is sprayed with quenching water to reduce the temperature of the flue gas to terminate the reaction, and the separated carbon black is sent to the In the process of wet mixing rubber, the carbon dioxide separated from the exhaust gas after combustion is used in the production process of white carbon black, and nitrogen is used in the wet mixing process, and a large amount of heat generated is used in the production process of white carbon black and wet mixing. used in the process.

Embodiment 2
[0101] The fuel oil is pumped to be mixed with the air provided by the main supply fan and preheated to 850°C by the air preheater, and then combusted in the combustion section to generate a high-temperature combustion airflow of about 1900°C; the raw material oil is preheated to a certain temperature by the preheater After that, it is sprayed into the throat section of the reaction furnace, mixed with the high-temperature combustion airflow, and rapidly cracked to produce carbon black flue gas; then, it is sprayed with quenched water to reduce the temperature of the flue gas to terminate the reaction, and the separated carbon black is used after passing through the bag filter. In the process of wet mixing rubber, the carbon dioxide produced by the combustion of tail gas in the tail gas boiler is used in the production process of white carbon black, and the heat generated is used in the process of white carbon black and wet mixing.
